Description

The pressing type theftproof lock

The utility model relates to a kind of lockset, specifically a kind of pressing type theftproof lock.

Lockset in the prior art is made up of lock body and key, a lock core is only arranged in the lock body, the relative motion face of lock core and lock body is a cambered surface, utilize the serrated face of key pellet shot from a slingshot jack-up arranged in a straight line to be made lock open, lock core made the pellet shot from a slingshot unbalance stress with the relative cambered surface motion of lock body when its weak point was to unblank, precision is low, poor reliability.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and pressing type theftproof lock that a kind of precision height, good reliability are provided.

To achieve these goals, the utility model provides a kind of new technical solution: this pressing type theftproof lock is made up of lock body and key, lock body is by deciding core, moving core, pad, lock pin, press key, pellet shot from a slingshot is formed, deciding core and moving core pastes mutually and can carry out relative motion, and different pellet shot from a slingshot hole, aperture before and after corresponding being respectively equipped with, the pellet shot from a slingshot hole of two in-core larger apertures is corresponding, nail-shaped pellet shot from a slingshot that matches and pellet shot from a slingshot place respectively in the pellet shot from a slingshot hole of deciding core and moving core, the pellet shot from a slingshot spring of moving in-core is pushed pellet shot from a slingshot to pellet shot from a slingshot respectively, spill is pressed key will decide core and is moved the core hoop in recessed, it forms keyhole corresponding to the space between one side of deciding core and the pellet shot from a slingshot, one side corresponding to moving core is provided with pressure key wheel and presses the key spring, press the key spring to rely on lock body will press key integral body to push decide the core direction to, step-like pressure lock is positioned at moving core and presses between the key wheel, and pad can be done motion in the same way by the moving core of moving core cassette tape, and the top of moving core is provided with lock pin, the lock pin of cranking arm is positioned between moving core and the lock pin, and lock pin can stretch on lock body; Be provided with on the key corresponding to the depth of deciding core different half through hole and through hole.

The utlity model has advantages such as precision height, good reliability, purposes be wider.

Accompanying drawing is embodiment of the present utility model.

Fig. 1 is the utility model structural representation.

Fig. 2 is lock core state diagram before pad is compressed into.

Fig. 3 is that pad is compressed into the rear lock core state diagram.

Below in conjunction with accompanying drawing and concrete embodiment essentiality content of the present utility model is described in further detail.

Among the figure, the 1--lock body, 2--decides core, and 3--moves core, 4--pad, 5--lock pin, 6--lock pin card, the 7--lockpin spring, the 8--keyhole, 9--presses key, and 10--presses key wheel, 11--pellet shot from a slingshot, 12--presses the key spring, and 13--moves core card, 14--key, 15--pellet shot from a slingshot hole, 16--pellet shot from a slingshot spring, 17--pellet shot from a slingshot

As shown in the figure, this pressing type theftproof lock is made up of lock body (1) and key (14), lock body (1) is by deciding core (2), moving core (3), pad (4), lock pin (5), press key (9), pellet shot from a slingshot (11) is formed, deciding core (2) and moving core (3) pastes mutually and can carry out relative motion, and different pellet shot from a slingshot hole (15), aperture before and after corresponding being respectively equipped with, the pellet shot from a slingshot hole (15) of two in-core larger apertures is corresponding, nail-shaped pellet shot from a slingshot (11) that matches and pellet shot from a slingshot (17) place respectively in the pellet shot from a slingshot hole (15) of deciding core (2) and moving core (3), pellet shot from a slingshot spring (16) in the moving core (3) is pushed pellet shot from a slingshot (11) to pellet shot from a slingshot (17) respectively, spill presses key (9) will decide core (2) and moving core (3) binds round in recessed, it forms keyhole (8) corresponding to the space between one side of deciding core (2) and the pellet shot from a slingshot (17), one side corresponding to moving core (3) is provided with pressure key wheel (13) and presses key spring (12), press key spring (12) to rely on lock body (1) will press key (9) integral body to push decide core (2) direction to, step-like pressure lock (4) is positioned at moving core (3) and presses between the key wheel (10), pad (4) can drive moving core (3) by moving core card (13) and do motion in the same way, the top of moving core (3) is provided with lock pin (5), the lock pin card (6) of cranking arm is positioned between moving core (3) and the lock pin (5), and lock pin (5) can be gone up flexible at lock body (1); Have the depth different half through hole and through hole on key (14) face.During use, insert key (14) in keyhole (8), with holes towards pellet shot from a slingshot (17), and this moment, lock core was in state shown in Figure 2.Be pressed into step-like pad (4), press key wheel (10) to oppress key spring (12) with pad (4) movement locus, press key (9) key (14) to be pressed to pellet shot from a slingshot (17) thereupon, be provided with the different pellet shot from a slingshot of length (17) and pellet shot from a slingshot (11) and corresponding pellet shot from a slingshot hole (15) corresponding to key (14).Being pressed into pellet shot from a slingshot (11) in the moving core (3) of pad (4) gets back in the pellet shot from a slingshot (15) in moving core (3) interface, be in state shown in Figure 3, pad (4) drives core (3) to the top motion by moving core card (13) simultaneously in course of action, and pushes lock pin card (6) and compress lockpin spring (7) lock pin (5) is regained in the lock body (1).Aforesaid operations is reversed then extended lock pin (5) and withdraws from key (14).
