Description

A kind of novel idle running anti-prizing type lock

[technical field]

The utility model relates to the tapered end of lockset kind, especially a kind of novel idle running anti-prizing type lock.

[background technology]

The tapered end of traditional lockset only need use some simple tools just can open, poor stability, in order to strengthen the pick-proof of lockset, thief-proof function, some locksets manufacture and design company and develop lock core and can dally with respect to left 360 degree of lock body by lock core when non-lock key or other instruments insert, the tapered end that dead bolt does not link with lock core, as depicted in figs. 1 and 2, this lock head structure complexity, manufacture craft is loaded down with trivial details, the top of hoodle and the crimping of hoodle spring force, frequently unblank to cause easily the spring of hoodle to take the least important seat at a square table, influence tapered end application life, the lower surface of hoodle central slot is the inclined-plane, though the plug of Key, but cause tapered end mutual opening rate height, reduced the anti-theft security performance of lockset, do not have the safeguard function of lockset.

[utility model content]

The utility model has the advantages that provides a kind of simple in structure, easy to use, and manufacture craft is easy, and key is walked crosswise locking, and the tapered end mutual opening rate is low, and hoodle is provided with the take the least important seat at a square table novel idle running anti-prizing type lock of structure of anti-spring.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of novel idle running anti-prizing type lock, comprise lock gall, the courage cover, hoodle, the hoodle spring, locking plate and connector, locking plate horizontally slips in lock gall, the clamping block on the balanced no inclined plane that is provided with the locking hoodle at interval on the locking plate, the close connector side of hoodle are provided with the square groove that matches with clamping block on the locking plate, are provided with lock slots in the described connector, be provided with the lock gall fixture block that horizontally slips in the lock slots, the left side of lock slots is provided with and promotes the spring that the lock gall fixture block moves to right, and is provided with the lock gall draw-in groove that cooperates with the lock gall fixture block in the lock gall end, is provided with the button that the control lock stator moves to left in the lock gall outer end.

The upper and lower side of the clamping block on the described locking plate is the plane.

The upper and lower medial surface of described hoodle square groove is the plane.

Described hoodle top is provided with the projection that prevents that the hoodle spring from taking the least important seat at a square table.

Described lock gall is provided with at least one row's hoodle, and each hoodle upper end is connected with the hoodle spring.

Lock slots in the described connector is an eccentric grove.

Described connector and lock gall inner for half cycle to chute be connected.

The beneficial effects of the utility model are:

Hoodle top in the utility model lock gall is provided with the projection that prevents that the hoodle spring from taking the least important seat at a square table, the process of plug key can effectively avoid hoodle spring and hoodle to break away from, influence the normal use of tapered end, in addition, after outside key is extracted lock gall, hoodle all withstands on the inwall side of courage cover, make clamping block on the locking plate in the outside of hoodle square groove, locking plate ejects the lock gall fixture block lock gall draw-in groove of lock gall simultaneously, when rotating lock gall when the key that does not match or by other external force, lock gall idle running, link head can not rotate, reach the locking idling conditions, effectively reach the idle running tamper-resistant function of lockset.

[specific embodiment]

A kind of novel idle running anti-prizing type lock, as shown in Figure 1, comprise lock gall 1, courage cover 2, hoodle 3, hoodle spring 4, locking plate 5 and connector 6, locking plate 5 horizontally slips in lock gall 1, the clamping block 50 on the balanced no inclined plane that is provided with the locking hoodle at interval on the locking plate 5, close connector 6 sides of hoodle 3 are provided with the square groove 30 that matches with clamping block 50 on the locking plate 5, and connector 6 is connected to chute 10 with the half cycle of lock gall 1 the inner, in connector, be provided with eccentric lock slots 60, be provided with the lock gall fixture block 61 that horizontally slips in the lock slots 60, the left side of lock slots 60 is provided with and promotes the spring 62 that lock gall fixture block 61 moves to right, and lock gall fixture block 61 right sides slide into the lock gall draw-in groove of establishing in lock gall 1 end 63, and the locking plate 5 that promotes in the lock gall 1 moves to right, and is provided with the button 7 that control lock stator 5 moves to left in lock gall 1 outer end.When key 8 inserts lock gall 1, hoodle 3 is under the elastic force effect of hoodle spring 4, hoodle 3 is corresponding with the tartar of key 8, after making the square groove 30 of hoodle 3 be on the same horizontal level, lock gall fixture block 61 in connector 6 lock slots 60 is under spring 62 active forces, promoting locking plate 5 enters in the square groove 30 of hoodle 3, when key 8 rotates, the lock gall 1 of interlock drives lock gall fixture block 61 and rotates, because the lock slots 60 in the link head 6 is eccentric, so drive link head 6 rotation shift forks with the lock gall fixture block 61 that lock gall 1 is connected with connector 6, reach door lock is opened, when promoting button 7 with female sensing lock gall 1 internal direction then, button 7 promotes locking plate 5 and is moved to the left, locking plate 5 promotes lock gall fixture block 61 and is moved to the left, like this, the lock gall 1 that lock gall fixture block 61 connects separates with connector 6, and the clamping block 50 on the locking plate 5 also separates with the square groove 30 of all hoodles 3 simultaneously, make the hoodle 3 can the easy on and off activity, at this moment the key 8 on the lock gall 1 can be extracted outside the lock gall 1 smoothly.

To shown in Figure 5, hoodle 3 tops in the utility model lock gall 1 are provided with the projection 31 that prevents that hoodle spring 4 from taking the least important seat at a square table as Fig. 3, and the process of plug key 8 can effectively avoid hoodle spring 4 and hoodle 3 to break away from, and influences the normal use of tapered end; In addition, as shown in Figure 5, after outside key 8 is extracted lock gall 1, hoodle 3 all withstands on the inwall side of courage cover 2, makes clamping block 50 on the locking plate 5 in the outside of the square groove 30 of hoodle 3, locking plate 5 ejects lock gall fixture block 61 the lock gall draw-in groove 63 of lock gall 1 simultaneously, when rotating lock gall 1 when the key that does not match or by other external force, lock gall 1 idle running, link head 6 can not rotate, reach the locking idling conditions, effectively reach the idle running tamper-resistant function of lockset.

The above embodiment for preferred embodiment of the present utility model, is not to limit practical range of the present utility model with this just, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
