The structure of the lock body 110 is the same as that of the prior art, and not described in detail herein, the lock body 110 is provided with a locking tongue, which can be ejected from the lock body 110 or retracted into the lock body 110, and is used to cooperate with a lock seat mounted on a door frame to open and close a door. The lock body 110 is provided with a second mounting hole 111, and the second mounting hole 111 is engageable with the screw 120 and is used for mounting the key cylinder 10.
During assembly, the screw 120 sequentially stretches into the second mounting hole 111 and the first mounting hole 26 to fix the lock cylinder 10 to the lock body 110, the first pulling member 50 is matched with the lock tongue, and the first pulling member 50 drives the lock tongue to pop out of the lock body 110 or retract into the lock body 110 in the rotation process along with the rotating shaft 40'. Wherein, the matching structure of the first pulling and pulling 50 and the lock tongue is just to refer to the prior art.
The working principle of the lock 100 provided in this embodiment is that when a matched key is inserted into the keyhole 35 of the lock core 10, the lock pin 33 and the lock core pin are reset, the key can drive the lock cylinder 30 to rotate and drive the transmission joint 90 and the rotating shaft main body 40 to rotate, and a plurality of pulling and dragging members fixed on the rotating shaft 40 'rotate along with the rotating shaft 40', and in the pulling and dragging rotation process, the lock tongue is pushed to pop up or retract from the lock body 110 to realize unlocking or locking.
The lock 100 provided in this embodiment can be applied to various doors with different thicknesses, and according to the thickness of the door, the first pull 50 and/or the second pull 60 can be selectively used to cooperate with the lock tongue, and the lock 100 can be manufactured in a large scale and is adapted to various doors in the market, so that the production cost is reduced.
The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the same, but rather, various modifications and variations may be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
