The quick locking device of anti-error lock resilient key tongue

Technical field the utility model relates to a kind of locking device, the quick locking device of especially a kind of anti-error lock resilient key tongue.

Background technology is used for the locking device of vehicle anti-theft at present, really is rich and varied multifarious, and for example: with the bicycle is the various wheel lock of the bicycle of representative; With the motorcycle electric door lock, head lock, wheel lock of the handle type motor vehicle of representative etc.; With the car electric door lock, handle lock, gear lever lock of the steering-wheel type motor vehicle of representative etc.; Especially practical and general in the middle of all these locking devices with the wheel lock, and with electric door lock for unique and strange, because they are promptly practical and universal, but theftproof performance is the poorest, and new-type motor vehicle steering wheel lock, protection defending lock be owing to be split type, and some is not only big but also heavy even, though so theftproof pretty good, but practicality is had a greatly reduced quality, to such an extent as to so and the mistake car of generation is the most general.The patent No. of Patent Office of State Intellectual Property Office bulletin in 26 days September calendar year 2001 is the anti-theft device for vehicle of ZL00261020.5, a kind of theftproof lock that is used for various vehicle steering shafts is proposed, this device realizes hindering moving of vehicle by the way of direct control steering spindle, thereby realize antitheft purpose, but because technology is immature, thereby its practicality is not good enough, the most direct result market of not opening exactly.

The summary of the invention the purpose of this utility model provide a kind of simple in structure, cost is lower, theftproof good, practical, operation anti-error easily lock resilient key tongue quick locking device

For achieving the above object, the utility model has adopted the innovation structure that pushes away handle based on resilient key tongue, anti-error lock, and is subsidiary again simultaneously with destination apparatus, as the technical targetedly processing of steering spindle.

As a kind of locking device, the utility model mainly partly is made up of three of latch, the lock core of control latch, the inner layer sleeve that wraps up latch and outer layer sleeves etc.

Wherein latch pushes away handle by anti-error lock again, the resilient key tongue has reached the spring first of interconnect function and has formed, anti-error lock pushes away handle except that anti-error locking device is housed, there is circular groove at its front end center, groove can make the spring first that connects itself and pin tongue that sufficient extendable room is arranged, the sidewall that anti-error lock pushes away handle has rectangular recess, can settle the V-arrangement reed in the groove or supply the dead bolt of built-in lock core to rotate, also be latch and external lock core, the important events of relevant contact take place in the latch inner layer sleeve, the main effect of spring first is to make the pin tongue promptly have toughness to have elasticity again, specifically, the one, push away the handle At time of eject with anti-error lock and will sell tongue and from the lockhole of locking target, take out of, the 2nd, when anti-error lock pushes away that handle advances the back and resilient key tongue still during the lockhole of misalignment locking target, this moment, the spring first was compressed, once the locking target is rotated or when mobile, the spring first can spring into the pin tongue in the lockhole of locking target at any time.

Lock core is divided into external and built-in two kinds again, the external lock core is installed on the latch inner layer sleeve wall, it controls latch by stretching of dead bolt, and built-in lock core is installed in the push handle of bolt, controls latch by the deflection of single blade-rotating shape dead bolt, no matter be external or built-in, after lock core was opened, key all can't be extracted, and can avoid forgetting like this with the lock core locking as far as possible, and having only just can the locking latch behind the locking lock core.

The ectonexine sleeve pipe of latch is except fixing and protection latch, and there is a little card article in the place that the latch inner layer sleeve is corresponding with the push handle of bolt rectangular recess, and little card article can limit going out of push handle of bolt, during as built-in lock pin, the V-arrangement reed is installed also herein; In order further to improve the performance of latch; also has the pad pipe in the latch sleeve pipe; the purpose of this pad pipe is to limit the degree of depth that push handle of bolt advances; with the dead bolt on the protection lock core, also have gasket ring, the critical function of this gasket ring in the latch sleeve pipe; its center drilling promptly is the path of pin tongue; again the pin tongue is shielded, a spring second is arranged between gasket ring and the push handle of bolt, spring second can will push away handle and outwards eject when lock core is opened.

The utility model is as being used to control vehicle steering shaft, promptly be called the quick locking device of anti-error lock resilient key tongue vehicle steering shaft, with the bicycle is example, its steering spindle is generally hollow section, form by two parts, the one, the top of connector handle, the one, the lower part of binding front-wheel, two parts interconnect by a deflation screw rod up and down, there is a sleeve pipe their outsides, sleeve pipe fuses they and vehicle body, like this, the quick locking device of anti-error lock resilient key tongue vehicle steering shaft just is installed on the sleeve pipe by wheel part steering spindle, so sleeve pipe just is equivalent to connect the collar of locking device and steering spindle, as long as open an adaptive hole of bore in the sleeve pipe place corresponding with the pin tongue, simultaneously also on steering spindle, open some adaptive holes or groove corresponding to the place of pin tongue, as open three, open on the front-wheel angle parallel for one with vehicle body, open at wheel to become with vehicle body on the angle at 45 degree angles for one, open on the wheel angle vertical for one with vehicle body, like this, when pin tongue locking, the bicycle front-wheel just can with vehicle body or parallel, or it is vertical, or become 45 to spend angles etc., such result appears, bicycle all can't normally be ridden, and especially back two kinds of bicycles as a result the time are normal to be carried out all not all rightly, so just prevents that other people from having stolen bicycle.Adopt the bicycle of such anti-theft lock device relatively to adopt the bicycle of conventional wheel lock, not only unlatching and locking are all very convenient, especially more can finish during locking in moment, easily as turning over the palm, fast like lightning, because anti-error locking device is arranged, the mistake lock does not take place and cause accident in the process of riding with regard to worrying yet, because the latch protective case is arranged, its anti-damage performance is also just as vehicle frame, simultaneously, since between latch protective case and the latch inner layer sleeve by some dowel fixes, once lockset can't normally open the time, is disassembled lockset thereby can look for special repairman with electric drill pin to be bored, and the repeated use of can regenerating, and the robber in the ordinary course of things can not be with electric drill.

Principle according to this, no matter motorcycle, automobile, or other vehicle, can install the quick locking device of anti-error lock resilient key tongue vehicle steering shaft, institute's difference is that bicycle has very adaptive steering spindle sleeve pipe, the steering spindle sleeve pipe of other vehicle is just not necessarily adaptive, this just need proceed from reality, as automobile, here the steering spindle of being said is to refer in particular to the vehicle steering bar, because its upstream device that to be Control of Automobile turn to, if the steering wheel column sleeve position is higher, then can this locking device be installed with sleeve pipe, if sleeve position is lower, then need be at the nearer local collar of installing earlier of distance steering wheel, and the collar is connected or is connected with sleeve pipe with nearest vehicle body position, and then it is just passable that this locking device is installed.As for other vehicle, the method for this locking device is installed, and roughly as above method is described.As everyone knows, a lot of motorcycles, automobile is stolen, be not that the car owner does not dispose extra lock, except some because of the carelessness or forget and enable the extra theftproof lock, most cases is to handle affairs the anxious working of car owner or short time not want to take the trouble and leave things to chance and be disinclined to additionally to lock, also has a kind of special situation, some car owner's vanity is too strong, worries to make two bites at a cherry that it is little to be seen by the people, or is seen little second car of oneself cannot afford by the people, though no small harm is done for vanity, be a kind of objective reality after all, and the face that exists is also very big, and appearance of the present utility model, to make above situation change fully, the convenience of its use can not given any puzzlement of car owner again, and it is easily as turning over the palm, fast lock operation like lightning, it is worried into vanity that people needn't be taken time again, and hope can become loved by all theftproof lock.

The utility model also can be used for the vehicles such as aircraft, steamer except that above purposes.

The utility model under normal unmanned situation antitheft, can also when vehicle taking place be robbed urgent antitheft usefulness of robbing, because this locking device is after unlatching, key can be pulled out, therefore, as when being robbed accident, the car owner can moment with the steering spindle locking, experienced car owner can be hidden in key hidden part in advance, even next the car owner loses resistance, the robber is because of can't steering vehicle, and it is plundered purpose and also just can't realize, as long as robber's main purpose is the misfortune car, rather than other, the misfortune car of believing difficulty like this will inevitably frighten many robbers away, thereby the case incidence of cases of plundering vehicle is from now on reduced greatly, and present anti-theft lock for vehicle still can't finely be accomplished this point.

Because the innovation part of this practicality is that anti-error lock pushes away handle and resilient key tongue; therefore; the adaptive anti-error locking device of other any function that pushes away on the handle all should drop on protection domain of the present utility model; equally; other any functionally similar resilient key tongue also should drop on scope of patent protection of the present utility model.

Anti-mislocking spring tongue quick locking device shown in Figure 1 and error preventing lock resilient key tongue fast lock shown in Figure 2 The lock core (18) of device is placed different, and structure is also slightly different, and the former lock core (18) is placed on the internal layer cover On the pipe (14), dead bolt (17) can be elastic, and V-arrangement reed (16) is positioned at rectangular recess (3) bottom, Push away in handle (1) rear portion and latter's lock core (21) is built in error preventing lock, dead bolt (20) is single blade-rotating shape, can be inclined to one side Turn to, V-arrangement reed (19) is positioned on the inwall of inner layer sleeve (14), in addition, and both other knots Structure is identical, mainly all pushes away handle (1), resilient key tongue (7), inner layer sleeve (14), skin by error preventing lock and protects Several most of compositions such as shell (13), wherein error preventing lock pushes away that handle (1) comprises again mistaken-locking prevention device (2), rectangle is recessed Groove (3), circular groove (4), this mistaken-locking prevention device (2) is made up of groove, spring, T shape card article, ring cowling, Error preventing lock pushes away handle (1) when being in opening, and spring outwards pushes up T shape card article, the part that T shape card article exposes Lean against inner layer sleeve (14) mouthful side of latch, the error preventing lock of this moment pushes away handle (1) and can't directly advance inwards, Only have that T shape card article is pushed down can when wall is equal to pushing away handle (1) with error preventing lock; Inner layer sleeve (14) inwall pair Should there be in the place of circular groove (4) card article (15), innermost end that one pad pipe (8) is arranged, pad pipe (8) distance The maximum length that error preventing lock pushes away handle (1) front end is slightly larger than error preventing lock and pushes away handle (1) and stretch out inner layer sleeve (14) section The length of dividing; Gasket ring (12) is close to pad pipe (8) and inner layer sleeve (14), and the thickness of gasket ring (12) is big Be equivalent to approximately 2/5ths of pin tongue (7) length; The two ends of spring first (5) are separately fixed at circular groove (4) The inner end and pin tongue (7) on, the two ends of spring second (6) are separately fixed at error preventing lock and push away the upper and gasket ring of handle (1) (12) on.

Shown in Figure 1 is lock core (18) locking and anti-mislocking spring tongue quick locking device is in the shape when opening Attitude, wherein error preventing lock pushes away handle (1) and blocks elasticity by spring second (6) ejection and by card article (15) at this moment Pin tongue (7) is subjected to the traction of spring first (5) and pushes away inward indentation of handle (1) with error preventing lock, when the user pins anti-The T shape card article of mistake locking device (2) pushes away handle (1) with error preventing lock and inwardly pushes away, and what run into dead bolt (17) stops V Shape reed (16) be subjected to dead bolt (17) extruding and in close, error preventing lock pushes away handle (1) to be continued to move ahead until be subjected to Stop to move ahead to stopping fully of pad pipe (8), error preventing lock pushes away handle (1) and has entered the internal layer cover fully at this moment Pipe (14), thereafter, V-arrangement reed (16) also launches again because having broken away from dead bolt (17), at this moment, dead bolt (17) stop that again V-arrangement reed (16) is in the opposite direction mobile, also just so that error preventing lock pushes away handle (1) Can not retreat, meanwhile, spring second (6) is compressed, and resilient key tongue (7) is pushing away in spring first (5) also Moving lower outwards stretching, extension, thus realize the locking target. On the contrary, if releasing just need be used key to the locking of target Spoon opening lock master (18) inwardly shrinks dead bolt (17), thereby makes V-arrangement reed (16) break away from dead bolt (17) Stop, spring second (6) so error preventing lock is pushed away outwards bullet of handle (1) because the elastic force of spring second (6) system Number will be much larger than the spring ratio of spring first (5), therefore, no matter whether resilient key tongue (7) can breakaway Lockhole, error preventing lock push away handle (1) and are certain to be ejected, the T shape card article automatic spring of mistaken-locking prevention device (2), Locking lock core (18) again, and key extracted, generally resilient key tongue (7) is to break away from easily order The mark lockhole, in particular cases, the general a little activity target once that only needs can be taken off resilient key tongue (7) From the target lockhole. Locking and the opening process of an anti-mislocking spring tongue quick locking device have so also just been finished.

The process of the anti-mislocking spring tongue quick locking device of the built-in lock pin that locking and unlatching are shown in Figure 2 and above-mentioned Basic identical, institute's water part is that dead bolt (20) is deflectable rather than flexible, is V-arrangement reed (19) Stop that dead bolt (20) rather than dead bolt (20) stop V-arrangement reed (19).

Shown in Figure 3 is the state of anti-mislocking spring tongue quick locking device practical application on vehicle steering shaft, Steering spindle shown here (10) is hollow pipe, and in the practice, the steering spindle of bicycle namely is so, and automobile Or the steering wheel column of other vehicle then generally is solid, and therefore, the indication steering spindle comprises hollow shaft and reality here Axle, this steering spindle (10) has been overlapped a steering spindle collar (11), and anti-mislocking spring tongue quick locking device is then Be fixed on the steering spindle collar (11), and for bicycle, the steering spindle sleeve pipe just arranged itself, this turns to Also just be equivalent to the steering spindle collar (11) to pipe spreader, the steering spindle collar (11) is upper corresponding to gasket ring (12) There is the identical hole of a bore in the place of centre bore, and three holes are arranged on the steering spindle (10), and they are called steering shaft lock Hole (9), and be groove in fact for solid steering spindle, also be called the steering spindle lockhole, for general vehicle, have Three steering spindle lockholes (9), namely practical, can do special-purpose again, also enough, as by bicycle, First steering spindle lockhole makes front-wheel and vehicle body parallel after lock can being closed, and the 3rd steering spindle lockhole can Making front-wheel vertical with vehicle body after lock is closed, and second steering spindle lockhole, namely in the middle of that, then can with Make front-wheel become 45 degree or arbitrarily angled between zero to 90 degree with vehicle body after lock closes, this is general Nature in the situation during bicycle parking, about the same in 45 degree shown in this figure. When error preventing lock pushes away When handle (1) ecto-entad advances, push resilient key tongue (7) to steering spindle lockhole (9) by spring first (5), When the centre bore of steering spindle lockhole (9) and gasket ring (12) fitted like a glove, resilient key tongue (7) also just straight Insert steering spindle lockhole (9), yet steering spindle lockhole (9) is more or less opened gasket ring (12) partially most the time Centre bore, therefore, when, when resilient key tongue (7) can't enter steering spindle lockhole (9), along with anti-error Lock pushes away the fully propelling of handle (1), and spring first (5) is understood pressurized and compressed, once wait until steering spindle lockhole (9) When roughly coincideing with the centre bore of gasket ring (12), resilient key tongue (7) will be by the elastic force of spring first (5) Insert steering spindle lockhole (9), thereby finish the locking target. No matter owing to vehicle, boats and ships, aircraft etc., they Can not keep motionless fully in the traveling process steering spindle, therefore, because by spring first (5), complete After becoming error preventing lock to push away the propelling of handle (1), no matter whether resilient key tongue (7) inserts steering spindle lockhole (9), its Can give tacit consent to resilient key tongue (7) has inserted steering spindle lockhole (9) in fact, has namely realized the lock to target Therefore close, can say that also the utility model can finish the locking program fast in moment. Simultaneously, owing to had anti-Mistake locking device (2), short of unlatching mistaken-locking prevention device (2) also just can be avoided because of the accident collision error preventing lock Push away handle (1) and cause the false locking target and the relevant traffic accident that causes.

No matter the specific embodiment is the quick locking device of built-in anti-error lock resilient key tongue, or the quick locking device of the anti-error lock resilient key of external tongue, their antitheft principle all is the same with theftproof performance, but, owing to need certain work plane and work range when using key operated locking device, therefore, their compliance and structural advantages have separately also just been determined, the quick locking device of anti-error lock resilient key tongue as external, the miniaturization that just might more become of its latch than the latch volume of the quick locking device of anti-error lock resilient key tongue of external, and the built-in quick locking device of anti-error lock resilient key tongue is because lock core is contained in push handle of bolt inside, therefore, its moulding is also just more succinctly standardized, also comparatively attractive in appearance this.For the quick locking device of the anti-error lock resilient key of vehicle steering bar tongue,,,, then adopt the relatively good of external for the facility of opening such as the back side that can be contained in steering wheel column if will adorn more hiddenly.

When application is when being the bicycle of representative with the bicycle: the position of selecting the quick locking device of this anti-error lock resilient key tongue of installation should be on the steering spindle sleeve pipe of the steering spindle of correspondence connection vehicle front-wheel, rather than the rotating shaft of hundle-bar, because the front-wheel steer axle of bicycle and handle rotating shaft are separately independently, just link together between them by fastening screw, at first be on steering spindle, bore one with the more bigger hole of the centre bore of gasket ring, on corresponding to the steering spindle in this hole, bore three equirotal lockholes then, steering spindle herein is hollow steering spindle, for solid steering spindle then is to bore three locked grooves, the depth of locked groove wants to guarantee normally locking steering spindle of resilient key tongue, in general, three lockholes are meant, when wheel is parallel with vehicle body, wheel is vertical with vehicle body to be, steering spindle was corresponding to the determined lockhole in the position in the hole on the steering spindle sleeve pipe when wheel became about 45 to spend angles with vehicle body.It then is the shape of determining the outer protective case of good latch, because the steering spindle sleeve pipe is a tubulose, therefore, the latch protective case has been determined shape with the steering spindle sleeve pipe, follow by general assembly, the requirement that must fit like a glove with the hole on the steering spindle sleeve pipe according to the gasket ring centre bore, the quick locking device of anti-error lock resilient key tongue vertically is placed on the steering spindle sleeve pipe, at last again with the latch protective case and the steering spindle sleeve pipe is firm welds together, so also just finished all installation works, the quick locking device of the anti-error lock resilient key of turning of bicycle axle tongue has just been finished.

For automobile, steamer, aircraft and other vehicle, mainly be that the quick locking device of anti-error lock resilient key tongue is installed on steering wheel, concrete mounting method is the same substantially with bicycle.

Though the quick locking device of the anti-error lock resilient key of the steering spindle of bicycle, automobile, steamer, aircraft or other vehicle tongue, its using method basically identical.

The quick locking device of anti-error lock resilient key tongue that the locking lock core is external: at first, the card article that pushes away the anti-error locking device on the handle with a finger presses no longer blocks the inner layer sleeve of latch up to card article, then, take advantage of a situation and to push away handle with other finger or the centre of the palm and push inward, enter fully in the latch inner layer sleeve up to pushing away handle, in this process, the V-arrangement reed will be locked by the dead bolt on the lock core automatically, anti-thrust handle resilience is gone out, because the pin tongue is a rubber-like, the pin tongue directly just inserts lockhole or the locked groove on the steering spindle, the pin tongue temporarily can't insert, and the spring first that sell on the tongue this moment will be compressed, once, when lockhole on the steering spindle or locked groove corresponded essentially to the pin tongue, the pin tongue was at the lockhole or the locked groove that can insert automatically under the elastic force effect of spring first on the steering spindle.

Open the external quick locking device of anti-error lock resilient key tongue of lock core: make in the dead bolt with key operated lock core and contract, this moment, the V-arrangement reed no longer was subjected to the restriction of dead bolt, push away handle to be subjected to the elastic force effect of spring second and eject the latch inner layer sleeve, because the restriction of card article on the internal surface of sleeve pipe is arranged, pushing away handle can only partly eject, along with pushing away going out of handle, the T shape card article of anti-error locking device ejects again, the pin tongue can leave the steering spindle lockhole under the traction of spring first, even being subjected to the extruding of steering spindle lockhole, the pin tongue temporarily can not leave, because pushing away handle goes out, the spring first can be stretched, once steering spindle is when rotating a little, the pin tongue just can leave the steering spindle lockhole, after ejecting, handle just lock core locking again so just can have been finished whole opening process as long as push away.

Locking or the open operation process and the said method basically identical of the quick locking device of anti-error lock resilient key tongue of built-in lock pin, difference are that dead bolt is deflection rather than flexible, are V-arrangement Reed lock lock tongue and dead bolt locking V-arrangement reed not.

No matter lock core is external or the quick locking device of anti-error lock resilient key tongue of built-in lock pin, from opening the back behind locking, lock core is in locking states all the time, and, lock core key after unlatching can't be extracted, so just can guarantee to greatest extent that lock core only is only unlatching when needs are opened the quick locking device of anti-error lock resilient key tongue, it At All Other Times locking all the time, also just guaranteeing fully at any time can be in the very short time, or even just can finish locking to the quick locking device of anti-error lock resilient key tongue in moment, steal when robbing locking rapidly as being implemented, really play and use rapid and convenient and effective antitheft purpose at vehicle.
