Description

Multi-functional rod formula automobile anti-theft lock

The utility model relates to a kind of automobile anti-theft lock, the particularly relevant anti-theft column lock that is contained on the vehicle steering.

Up to the present, the multiple rod formula lock that is attached on the vehicle steering has appearred, for example: contain the mechanical structure form that prolongs holding device that pipe or rod, lock core assembly, big hinge and little hinge form or similar holding device etc.; The multifunction structure form that installs electronic alarm device on the physical construction basis additional is also arranged.These locksets all have preferably pick-proof mostly, anti-ly draw, protecting against shock, anti-saw function and warning function, but also there is weak link, be that the lock core assembly of these locksets normally adopts outside the part of soft material makes and be exposed to, be easy to be destroyed at short notice by drilling tool, safety is affected, thereby the comprehensive theft performance of these locksets is not high.

The purpose of this utility model is to provide a kind of multi-functional rod formula automobile anti-theft lock, and its structure has higher anti-drilling ability, thereby improves its comprehensive theft performance.

In order to achieve the above object, multi-functional rod formula automobile anti-theft lock of the present utility model, comprise and prolong pipe, big hinge, little hinge and lock core assembly, in prolonging pipe electronic alarm device is housed, big hinge is captiveed joint with the prolongation pipe, on the big hinge lock core assembly is housed, hinged between big hinge and the little hinge with pivot pin, the lock core assembly has outside anti-drill bushing, in the anti-drill bushing anti-drilling sheet is housed, and anti-drilling sheet is covered with lock core and the anti-drilling sheet center has the through hole that penetrates for key.

The through hole at anti-drilling sheet center can be split into the yi word pattern through hole, but preferably is split into cross through hole.

After adopting said structure, because the lock core assembly has in outside anti-drill bushing and the anti-drill bushing anti-drilling sheet is housed, anti-drilling sheet is covered with lock core, so if will bore inner body such as bad lock core, necessary subdrilling bad or anti-drill bushing of destruction and/or anti-drilling sheet, and anti-drill bushing and anti-drilling sheet have very high hardness, and anti-drilling sheet can also rotate with drilling tool, make drilling tool be difficult to pierce at short notice and destroy parts such as lock core, therefore multi-functional rod formula automobile anti-theft lock of the present utility model has very high anti-drilling ability, and the comprehensive theft performance is improved.In addition, when key inserted the lock core assembly, anti-drilling sheet can rotate with key, lock core etc., opened flexibly, did not hinder.

The utility model is described in further detail below in conjunction with embodiment that accompanying drawing provides.

As shown in Figure 1, 2, 3, a kind of multi-functional rod formula automobile anti-theft lock of the present utility model comprises prolonging manages (1), big hinge (2), little hinge (3) and lock core assembly (4), the electronic circuit board component (not drawing among the figure) of electronic alarm device is housed, lamp assembly (5), indicator lamp (6) and buzzer phone (7) etc. in prolonging pipe (1).Big hinge (2) is captiveed joint with prolongation pipe (1), can be force fit or welding, riveted joint.The battery holder assembly (8) of electronic alarm device is housed in the big hinge (2), in the boss (9) on the big hinge (2) lock core assembly (4) is housed.As shown in Figure 3, the dead bolt (10) of lock core assembly (4) can insert in the lock tongue slot (11) of little hinge (3), plays the little hinge of switch (3), and the notch of lock tongue slot (11) is blocked by jam (111).Hinged between big hinge (2) and the little hinge (3) with pivot pin (12).Shown in Fig. 4,5, lock core assembly (4) contains lock housing (14), spring (15), pellet shot from a slingshot (16), lock core (17) and dead bolt (10), is connected with pin (18) between lock core (17) and the dead bolt (10).Lock core assembly (4) has outside anti-drill bushing (19), in the anti-drill bushing (19) anti-drilling sheet (20) is housed, and anti-drilling sheet (20) is covered with lock core (17).Shown in Fig. 4,6,7, anti-drill bushing (19) is the thin circular cylinder body of an end band reducing, anti-drill bushing (19) is enclosed within on the lock housing (14), one end of anti-drill bushing (19) has reducing and stomidium (21), anti-drilling sheet (20) is located in the below of this reducing and stomidium (21), because the aperture of stomidium (21) is less than the external diameter of anti-drilling sheet (20), thereby anti-drilling sheet (20) is subjected to the restriction of reducing, can not drop out.Shown in Fig. 8,9, anti-drilling sheet (20) is a disk, and the center has the through hole (22) that penetrates for key (13) (seeing Fig. 2, Fig. 3), and the shape of through hole (22) is cross through hole, and purpose is can simultaneous adaptation one letter lock core or cross lock core.Anti-drill bushing (19) and anti-drilling sheet (20) are all through bakingout process, and hardness is very high, within HRC52～62 scopes.

During use, the through hole (22) with key (13) insertion anti-drilling sheet (20) enters lock core (17), and anti-drilling sheet (20) together rotates with key (13), lock core (17), dead bolt (10) etc., without any obstruction.Anti-drilling sheet (20) can rotate with drill bit when running into the drilling tool drilling, and drill bit is difficult to destroy anti-drilling sheet (20).Because anti-drill bushing (19) and anti-drilling sheet (20) have high hardness, thereby can protect whole lock core assembly unlikely destroyed easily.

Certainly, the periphery of anti-drill bushing is not limited to circle, also can be other suitable shapes such as polygon; The through hole at anti-drilling sheet center can also be the yi word pattern through hole, and anti-drilling sheet also can be curve forms such as straw hat shape, and these all are subjected to protection of the present utility model.
