In specific application, in order to facilitate installation and use of the lock, the connecting portion 101 of the lock body 10 is provided with a plurality of mounting holes 102, and the mounting holes 102 can be respectively located on two sides and a lower end face of the connecting portion 101, so that when the lock is installed, an installation mode can be selected according to actual conditions. After the lock is installed, the unused installation hole 102 can be sealed by using a sealing plug 103, so that dust is prevented from entering the lock body 10. Also, for the convenience of assembly, a mounting hole 102 may be provided on the front side of the connecting portion 101, the mounting hole may be used for assembling the locking member 3, and the mounting hole 102 may be blocked by a sealing plug 103.
Further, as an optional implementation manner of this embodiment, the lock pin rotating shaft 20 is further provided with a positioning groove 204, the positioning groove 204 may be disposed on an outer side surface of the lock pin rotating shaft 20, a depth of the positioning groove 204 is shallow, and a side wall thereof may be an arc surface. When the lock body 10 is unlocked and rotated to the position of the positioning slot 204, the front end of the locking member 30 can extend into the positioning slot 204, so that the lock body 10 is prevented from rotating randomly, and when the lock body is locked, the front end of the locking member 30 can be separated from the positioning slot 204 by applying a certain external force due to the shallow depth of the positioning slot 204 and the arc-shaped side wall.
The embodiment of the utility model provides a lock with an operation hole, which locks the lock body 10 by matching the locking piece 30 with the locking groove 201 of the locking pin rotating shaft 20; during the unblock, utilize the lock to turn round 60, unblock piece 40 and the cooperation of dialling round pin 41 and stir latch 30 and realize the unblock to when the unblock, through the lower of the baffle 50 that resets remove block the reset of unblock piece 40, make the key turn round 60 the back and can extract at the rotation lock, and lock body 10 can make the baffle 50 that resets move up and reset when rotating the unblock, has improved the practicality of tool to lock, and the utility model discloses a tool to lock, its compact structure, it is reliable to separate the shutting.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the present invention.
