Description

A kind of single tongue pellet shot from a slingshot double hook theftproof lock

The utility model relates to a kind of improvement of locking device, and it is applicable to the cylinder lock of single tongue.

Lock is one of necessary tool in people's daily life, how to make it accomplish safety, reliable, really play antitheft effect, one is made us problem deeply concerned really, and the improvement of many technical scheme propositions to it arranged for this reason, for example Chinese patent CN94211863.4 number about mentioning the totally enclosed door lock of a kind of integral body in " duplex is prevented safety door latch ", it have anti-pound, anti-saw, tamper-resistant function, but the structure more complicated, need two key operated, use trouble, and the manufacturing cost height.

Task of the present utility model provides a kind of single tongue cylinder lock of new structure, it rational in infrastructure, and pick-proof, anti-saw ability strengthen, and make simple, easy to use, safe and reliable.

Task of the present utility model is finished in such a way, it is that movable hook is housed in the dead bolt both sides of single tongue cylinder lock, these two hooks and activity template are riveted together, and hook can be around the movable eye rotation of this junction, when movable control strip and dead bolt advanced, two hooks are subjected to lock housing to be stopped and hooks the lock housing external surface firmly.Use the ability of the anti-saw of this lock, pick-proof to strengthen significantly.

Below in conjunction with accompanying drawing the utility model is further elaborated.

Fig. 1 is a lock front view of the present utility model.

Fig. 2 is a double hook device schematic diagram of the present utility model.

Fig. 3 is a movable safety plate exploded view of the present utility model.

Fig. 4 is a lock housing stator exploded view of the present utility model.

Fig. 5 is lock housing inside structure figure of the present utility model.

Can see from Fig. 1, two hooks (2) are equipped with in the dead bolt of this single tongue cylinder lock (1) both sides, these two hooks (2) and dead bolt (1) all can extend to the outside of lock housing (4) from the inside of lock body (3), hook (2) is hooked on the external surface of lock housing tightly, and the locking ability of dead bolt (1) is strengthened.

Fig. 2 then is two hooks (2) schematic representation of apparatus, these two hooks (2) are to be riveted together with activity template (5), hook (2) can be around movable eye (6) rotation of junction, and activity template (5) is to hold together with movable control strip (7), and dead bolt (1) is to be inlaid on the movable control strip (7).When dead bolt (1) when moving forward, movable control strip (7) also drives hook (2) and moves forward, make the crotch up and down (8) of two hooks (2) run into lock housing (4) like this, hook (2) will be around (6) deflection of movable eye, thereby it is hooked on the shell surface of lock housing firmly.

Fig. 3 and Fig. 4 are contained in the movable safety plate (9) of lock housing (4) internal layer and the exploded view of lock housing stator (10), and Fig. 5 is the structure chart after their assemblings.Know by these map analysis, the public space (11) of movable safety plate (9) and lock housing stator (10) is suitable with dead bolt (1), an end of hook (2) can pass from this space (11) on the dead bolt (1) and two, the crotch of its other end (8) is then outside the scope of space (11), so when dead bolt (1) and hook after (2) pass space (11), crotch (8) then can be subjected to stopping of lock housing (4), makes hook (2) produce yaw motion, and two hooks hang on the lock housing firmly.In addition, the combination of activity template (9) and lock housing stator (10) can also be as trigger unit of warning device.

Claims (2)

1, a kind of single tongue pellet shot from a slingshot double hook theftproof lock of being formed by dead bolt (1), lock housing (4), it is characterized in that: hook (2) is housed in dead bolt (1) both sides, these two hooks (2) are to be riveted together with activity template (5), hook (2) can be around its movable eye (6) rotation, activity template (5) then is linked to be as a wholely with movable control strip (7), and dead bolt (1) is to be inlaid on the movable control strip (7).

2, press single tongue pellet shot from a slingshot double hook theftproof lock of claim 1 defined, it is characterized in that: public space of forming between movable safety plate (9) and the lock housing stator (10) (11) and dead bolt (1) sizableness, one end of hook (2) also can pass from space (11), and the crotch of its other end (8) is outside the scope of space (11).
