As shown in fig. 1 to 3, the utility model discloses a lock 100 with self-locking function, include: a lock body base 1, install in a lock hook 9 in the lock body base 1, a displacement sensor 2, a auto-lock slider 3, an unblock slider 4, one plays door shaft 5 cup joints a bullet door pressure spring 6 of bullet door shaft 5 cup joints a reset spring 7 of auto-lock slider 3 provides a extension spring 8 that resets of lock iron 10, and is located the outer lock iron 10 of lock body base 1.

In the locking process of the lock 100 with the self-locking function, the unlocking slide block 4 is far away from the self-locking slide block 3 to move, the lock iron 10 is rotationally locked on the lock iron 10 by means of the tension of the reset tension spring 8, and the self-locking slide block 3 stops the lock iron 10 from rotating towards the unlocking direction by means of the elastic displacement of the reset spring 7; in the unlocking process of the lock 100 with the self-locking function, the unlocking slide block 4 pushes the self-locking slide block 3 to displace and separate from the lock iron 10, and simultaneously pushes the lock iron 10 to rotate reversely to complete unlocking. Therefore, the purposes of self-locking during locking and convenience during unlocking are realized, and the device is simple in structure and low in cost.

Specifically, the self-locking slider 3 and the unlocking slider 4 slide in mutually perpendicular directions, the self-locking slider 3 includes a main body portion 31 and a limit guide post 32 formed by extending downward from the main body portion 31, the return spring 7 is sleeved on the limit guide post 32, the main body portion 31 has two self-locking moving guide posts 311, the moving guide posts are installed on the lock body base 1, a first inclined surface 312 and a first straight surface 313 connected with the first inclined surface 312, the unlocking slider 4 includes an installation portion 41 and a pushing portion 42 formed by extending from the installation portion 41, the thickness of the installation portion 41 is greater than that of the pushing portion 42, the installation portion 41 has a first unlocking guide post 411 and a second unlocking guide post 412 which are horizontally arranged, the first unlocking guide post 411 is located at a junction between the installation portion 41 and the pushing portion 42, and when unlocking is performed, the second unlocking guide post 412 pushes the locking hook 9 to be unlocked rotationally, the pushing portion 42 has a second unlocking guide post 421 and a second straight surface 422 connected with the second inclined surface 421, and the unlocking slider 4 abuts against the first inclined surface 421, so that the sliding block the locking hook 3 slides in a vertical direction, and the locking hook 312 is blocked in a vertical direction. In this example, for stability and convenience, the two self-locking moving guide posts 311 are arranged in a vertical direction, during locking, the locking hook 9 rotates in a counterclockwise direction, and during unlocking, the locking hook 9 rotates in a clockwise direction, in other embodiments, as long as the function of the lock with the self-locking function 100 can be realized, the number of the self-locking moving guide posts 311 and the rotation direction of the locking hook 9 may be in other forms, which is not limited herein.

The locking and unlocking processes of the lock 100 with the self-locking function of the utility model are described in detail as follows:

locking process: as shown in fig. 4 and 5, when the locking iron 10 is in the open state, the relationship among the self-locking slider 3, the unlocking slider 4, and the locking hook 9 is as follows: the self-locking slider 3 is limited by the first inclined plane 312 and is in an unlocking state, and the locking hook 9 is limited by the first unlocking guide column 411 and is in an opening state. As shown in fig. 6, an external force F moves the lock iron 10 downward, and a force F1 moves the latch shaft 5 toward the inside of the lock body base 1 against the elastic force of the latch compression spring 6; as shown in fig. 7, when the lock iron 10 reaches the position of completing being closed under the action of the force F, the latch shaft 5 triggers the displacement sensor 2 to generate a locking signal; as shown in fig. 8, after the displacement sensor 2 generates a locking signal, the unlocking slider 4 moves backwards under the action of a driving force Fb, and the locking hook 9 rotates against the potential needle to automatically lock under the action of the return tension spring 8; as shown in fig. 9, the relationship among the locking hook 9, the self-locking slider 3, and the unlocking slider 4 is as follows: the self-locking sliding block 3 is still limited by the second straight surface 422 and is in a non-reset state; the unlocking slider 4 is disengaged from the action on the locking hook 9; as shown in fig. 10, after the locking hook 9 is automatically locked, under the action of the driving force Fb, the unlocking slider 4 continues to move backward until the unlocking slider 3 is disengaged from the action on the self-locking slider 3, and the self-locking slider 3 moves and resets under the action of the return spring 7, so that the first straight surface 313 blocks the locking hook 9 from rotating counterclockwise, thereby realizing self-locking of the locking hook 9.

Unlocking process: as shown in fig. 11, when the lock 100 with the self-locking function receives an unlocking signal, the unlocking slider 4 generates an acting force Fjz to the self-locking slider 3 under the action of the driving force Fk; as shown in fig. 12, the force Fjz can be decomposed into a force Fjz (x) and a force Fjz (Y), and the self-locking slider 3 moves downward under the action of the force Fjz (Y) to achieve self-locking and unlocking of the locking hook 9; as shown in fig. 13, before the self-locking slider 3 is unlocked, a gap is maintained between the first unlocking guiding column 411 and the locking hook 9, and no force is applied to the locking hook 9; as shown in fig. 14, after the self-locking slider 3 is completely unlocked, the unlocking slider 4 continues to move under the action of the driving force Fk, and in the moving process, the first unlocking guide column 411 pushes the locking hook 9 to rotate clockwise, so as to unlock the locking hook 9; as shown in fig. 15, after the latch hook 9 is unlocked, the latch shaft 5 automatically pops the lock iron 10 under the action of the latch compression spring 6, and the position sensor generates a "door opening signal" to complete the whole unlocking process.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
