Referring to fig. 1 and fig. 2, fig. 1 and fig. 2 respectively show a perspective view and an exploded view of a lock, the axial locking mechanism includes a lock body 10 and a lock cylinder 40, one end of the lock cylinder 40 can extend into the lock body 10 along an axial direction of the lock body 10, and a limiting groove 403 is disposed on an outer periphery of the lock cylinder 40 (the limiting groove 403 in this embodiment is an annular groove disposed at an end of the lock cylinder 40). The lock body 10 is internally provided with an unlocking rotating shaft component 3, a jaw limit piece 32 and a jaw component 2, wherein the unlocking rotating shaft component 3 can be driven by a key to rotate, and the unlocking rotating shaft component 3 can drive the jaw limit piece 32 connected with the unlocking rotating shaft component to rotate while rotating; the jaw limiting piece 32 is provided with a locking part 324 and an unlocking part 323, and the unlocking part 323 and the locking part 324 rotate along with the jaw limiting piece 32; the pawl member 2 includes a locking pawl 20 and a pawl elastic member 21, the locking pawl 20 is swingably disposed in the lock body 10 and connected to the pawl elastic member 21, the locking pawl 20 has a stopper end 202 and a locking end 201, and the stopper end 202 can be inserted into the stopper groove 403 of the lock cylinder 40. Referring to fig. 3, fig. 3 shows a cross-sectional view of the lock when the lock is locked, when the locking portion 324 of the pawl limiter 32 rotates to face the locking pawl 20, the limiting end 202 of the locking pawl 20 extends into the limiting groove 403 of the lock cylinder 40, and under the action of the pawl elastic member 21, the locking end 201 of the locking pawl 20 abuts against the locking portion 324 to limit the limiting end 202 to exit from the limiting groove 403 of the lock cylinder 40, so that the lock cylinder 40 cannot be drawn out from the lock body 10; referring to fig. 4, fig. 4 shows a cross-sectional view of the lock when the lock is unlocked, in which the unlocking portion 323 of the pawl limiter 32 rotates to face the locking pawl 20, and under the action of the pawl elastic member 21, the locking end 201 of the locking pawl 20 cooperates with the unlocking portion 323 to make the limiting end 202 of the locking pawl 20 exit the limiting groove 403, so as to unlock the lock cylinder 40. In this way, the pawl stopper 32 is rotated by the unlocking rotary shaft assembly 3, so that the locking portion 324 or the unlocking portion 323 of the pawl stopper 32 faces the pawl member 2, thereby locking and unlocking the lock cylinder 40. In specific application, the lock cylinder 40 may be disposed in the cabinet body, the lock body 10 may be disposed in the cabinet door, when the cabinet door is close to the lock body 10, the lock cylinder 40 may extend into the lock body 10 and be locked by the claw member 2, thereby achieving locking of the cabinet door, and in contrast, when unlocking, the unlocking rotating shaft assembly 3 is rotated, the unlocking portion 323 of the claw limiting member 32 faces the claw member 2, so that the claw member 2 unlocks the lock cylinder 40, and at this time, the lock cylinder 40 may be pulled out from the lock body 10, i.e., the cabinet door may be far away from the cabinet body. In addition, when the axial locking mechanism in this embodiment is unlocked and locked, the unlocking rotating shaft assembly 3 and the jaw position limiting piece 32 both axially rotate and do not axially slide, and the relative positions of the unlocking rotating shaft assembly 3, the jaw position limiting piece 32 and the jaw part 2 can be kept fixed, so that the assembly accuracy of the unlocking rotating shaft assembly 3, the jaw position limiting piece 32 and the jaw part 2 can be kept unchanged, and the reliability of the axial locking mechanism in unlocking is ensured.

Specifically, in order to improve the reliability when the position limiting end 202 locks the position limiting groove 403, the position limiting end 202 may extend toward the position limiting groove 403. Further, the locking jaw 20 is provided with a coupling protrusion 204 for coupling the jaw elastic member 21, and in order to secure coupling reliability of the locking jaw 20 and the jaw elastic member 21, the jaw elastic member 21 may be coupled with a knock pin 22, and the jaw elastic member 21 abuts against the coupling protrusion 204 of the locking jaw 20 through the knock pin 22. More specifically, the jaw elastic member 21 may be a spring, one end of the jaw elastic member 21 is connected to the locking jaw 20 through the knock pin 22, and the other end of the jaw elastic member 21 may be connected to the inner wall of the lock body 10, in this embodiment, the jaw elastic member 21 may be located on one side of the locking jaw 20 close to the inner wall of the lock body 10, and during the unlocking and locking of the axial locking mechanism, the jaw elastic member 21 may not contact with other components including the jaw limit piece 32, that is, the jaw elastic member 21 may not interfere with the rotation of the jaw limit piece 32, thereby further improving the reliability of the axial locking mechanism.

Referring to fig. 3 and 4, as an alternative embodiment of the jaw stop 32 in the present embodiment, the locking portion 324 is substantially cylindrical, the locking portion 324 is a sidewall of an outer periphery of the jaw stop 32, the unlocking portion 323 is an unlocking slot 321 disposed on the outer periphery of the jaw stop 32, and the unlocking slot 321 may be disposed along a radial direction of the jaw stop 32 in the present embodiment. Referring to fig. 3, in the locked state, the locking end 201 of the locking pawl 20 abuts against the locking portion 324 of the pawl stop 32 (i.e. the side wall of the pawl stop 32) under the action of the pawl elastic member 21, and the limit end 202 of the locking pawl 20 is located in the limit groove 403 of the lock cylinder 40, so that the lock cylinder 40 cannot be drawn out from the lock body 10 under the limit of the locking portion 324 and the pawl elastic member 21; referring to fig. 4, during unlocking, the unlocking slot 321 of the pawl limiter 32 rotates to face the locking end 201 of the locking pawl 20, the locking end 201 of the locking pawl 20 extends into the unlocking slot 321 under the action of the pawl elastic member 21, and the limiting end 202 of the locking pawl 20 exits from the limiting slot 403 of the lock cylinder 40, so as to release the limitation on the lock cylinder 40, and at this time, the lock cylinder 40 can be pulled out from the lock body 10, and because the limiting end 202 of the locking pawl 20 is located in the unlocking slot 321, the pawl limiter 32 cannot rotate, which has the advantage of avoiding self-locking of the lock body 10, so that no key is needed during locking.

Referring to fig. 5, fig. 5 shows an exploded view of the unlocking rotating shaft assembly 3, specifically, the jaw position limiting member 32 may be cylindrical, an upper end of the jaw position limiting member 32 may be used to connect with the unlocking rotating shaft assembly 3, a lower end of the jaw position limiting member 32 is provided with an unlocking slot 321, and the unlocking slot 321 is connected to a side wall of the jaw position limiting member 32.
