DETAILED DESCRIPTION
[0014] Refer to Figs. 1 to 4 Further illustrate the utility model embodiment.
[0015] A lock with self-locking function, comprising a handle driving part 1, a latch assembly 2 and a reverse lock assembly 3, the reverse lock assembly 3 comprises a lock seat 30, a retractable reverse lock tongue 31 is arranged in the lock seat 30, and a rotationally matched unlocking assembly 4, by rotating the unlocking assembly 4 clockwise, the reverse lock tongue 31 is pushed to retract in the lock seat 30 to realize unlocking, and a retractable locking assembly 5 is further arranged, the locking assembly 5 is located at the middle position of the clockwise movement path of the unlocking assembly 4, the locking assembly 5 slides back and forth between the inside of the lock seat 30 and the outside of the lock seat 30, when the locking assembly 5 does not move towards the outside of the lock seat 30, the unlocking assembly 4 is in contact with the locking assembly 5 when rotating clockwise, so that it cannot move to the reverse lock tongue 31, the unlocking assembly 4 comprises a rotating seat 40 fixed in the lock seat 30, a rotating shaft 41 rotationally matched with the rotating seat 40, one end of the rotating shaft 41 close to the rotating seat 40 is provided with a push piece 42, and the other end is provided with an inner rotating head 43, an outer rotating head 44 is arranged on the outer cover of the inner rotating head 43, a plurality of limiting grooves 45 are distributed on the outer wall of the inner rotating head 43 at equal intervals in the circumferential direction, a plurality of clamping strips 46 are arranged on the inner wall of the outer rotating head 44 in the circumferential direction, a spring is arranged between the inner rotating head 43 and the outer rotating head 44, when the spring is in a relaxed state, the clamping strips 46 on the outer rotating head 44 are located above the limiting grooves 45 of the inner rotating head 43.
[0016] Two tripping grooves 47 are arranged on the push piece 42, the locking assembly 5 comprises a lock plate 50 and a pull block 51, wherein the pull block 51 is located outside the lock seat 30 and is provided with a compression spring 52 between the outer wall of the lock seat 30, the lock plate 50 is located in the lock seat 30, and the first end of the lock plate 50 is provided with a locking block 53 matched with the tripping groove 47. The reverse lock tongue 31 comprises a lock tongue block 310, a driving block 311 and a driving spring, the driving block 311 and the lock tongue block 310 are arranged perpendicular to each other, one end of the driving spring is in contact with the inner wall of the lock seat 30, and the other end is in contact with the driving block 311, so as to drive the end of the lock tongue block 310 to displace to the outside of the lock seat 30.
