Through the arrangement of the transmission block 3, when the transmission block 3 rotates, the transmission block 3 can drive the driven rod 4 and the locking plate 16 to rotate simultaneously, so that the locking plate 16 can move to the outside of the locking hole 2 to achieve unlocking. When the restriction on the transmission block 3 is released, the resilience of the torsion spring 17 can drive the locking plate 16 to reset. When the driven rod 4 rotates, the driven rod 4 can also drive the locking plate 16 to rotate through the transmission block 3.

[0023] In some embodiments of the present application, the locking plate 16 is connected to the shell 1 via a spring, one end of the spring is movably connected to the shell 1, and the other end of the spring is movably connected to the locking plate 16, and the resilience of the spring is used to reset the locking plate 16.

[0024] One end of the driven rod 4 extends to the upper side of the horizontal end of the housing 1 , and one end of the driven rod 4 is fixedly connected to an outwardly opened torsion plate 5 . When the driven rod 4 rotates, the driven rod 4 can drive the outwardly opened torsion plate 5 to rotate.

The other end of the rotating block 11 is located outside the shell 1. The other end of the rotating block 11 is connected to an inner opening wiring block 12. When the lock body is in use, a pull wire is connected to the inner opening wiring block 12. When the pull wire is pulled, the rotating block 11 can be driven to rotate through the inner opening wiring block 12. When the rotating block 11 rotates, it drives the transmission block 3 to rotate.

[0026] It can be known from the above description that when the lock body is in use, the rotation block 11 is driven by the pull wire to rotate, so that the lock body can be opened inwardly, and the rotation of the driven rod 4 can be driven to open outwardly.

Through the setting of the elliptical leaf spring 15, the anti-locking paddle 6 can rotate under the action of external force, and when the restriction on the anti-locking paddle 6 is released, the position of the anti-locking paddle 6 remains unchanged.

[0028] The vertical end of the anti-locking paddle 6 is located on the side of its horizontal end close to the outward twist plate 5, and when the vertical end of the anti-locking paddle 6 moves to the bottom of the outward twist plate 5, the anti-locking paddle 6 can limit the outward twist plate 5 to prevent the outward twist plate 5 from rotating, so that the lock body remains in a locked state.

[0029] A rotating groove is provided on the side of the top of the inner cavity at the horizontal end of the shell 1 away from the outer twist plate 5, and a card column 13 is movably connected in the inner cavity of the rotating groove. The bottom of the card column 13 is fixedly connected to the top of the rotating block 11, and a claw adapted to the card column 13 is provided on the horizontal end of the anti-locking paddle 6. When the vertical end of the anti-locking paddle 6 limits the outer twist plate 5, the claw limits the card column 13, thereby improving the locking reliability of the lock body. When the vertical end of the anti-locking paddle 6 is away from the outer twist plate 5, the claw is away from the card column 13, thereby releasing the restriction on the card column 13.

Through the setting of the locking wiring block 8 and the unlocking wiring hole 7, the locking wiring block 8 can be driven to move by the central control locking device connecting rod 20, and the locking connection block 8 can drive the anti-locking paddle 6 to rotate, so as to realize automatic locking of the lock body. The user can drive the unlocking wiring hole 7 to move by pulling the wire, and the unlocking wiring hole 7 can drive the anti-locking paddle 6 to rotate in the opposite direction, thereby realizing manual unlocking of the lock body, and the anti-locking paddle 6 can be rotated manually or by central control, thereby improving the adaptability of the lock body.

[0032] A wire drawing bracket 1 9 and a wire drawing bracket 2 10 are provided on the side of the shell 1 away from the outward twisting plate 5. The wire drawing bracket 1 9 and the wire drawing bracket 2 10 can be used to limit the position of the wire, so as to facilitate the movement of the wire.

[0033] To sum up: when the anti-locking mechanism of the car lock is used, if the lock body realizes the rotation of the anti-locking paddle 6 by manual mode, the other end of the central control locking device connecting rod 20 is connected to the central control connection point of the car, and the central control of the car realizes the pulling of the central control locking device connecting rod 20, a pull wire is connected to the anti-locking paddle 6 through the unlocking wiring hole 7, and another pull wire is selected to be fixed to the inner opening wiring block 12. When the central control of the car drives the locking wiring block 8 to rotate through the central control locking device connecting rod 20, the locking wiring block 8 can drive the anti-locking paddle 6 to rotate until the vertical end of the anti-locking paddle 6 is located below the outer opening twist plate 5. The lock body is in a locked state, and the other pull wire cannot drive the rotating block 11 to rotate. The lock body is in a locked state. The lock is in a locked state and cannot be opened. When the user manually drives the unlocking wiring hole 7 to rotate through the pull wire, the unlocking wiring hole 7 drives the anti-locking paddle 6 to rotate in the opposite direction, so that the vertical end of the anti-locking paddle 6 moves to the side of the outward opening twist plate 5. The lock body is unlocked. The user can drive the rotating block 11 to rotate through another pull wire, and the rotating block 11 drives the locking plate 16 to rotate through the transmission block 3. The lock body realizes the function of inward opening. The user can also drive the driven rod 4 to rotate from the outside of the car door, and the driven rod 4 can drive the locking plate 16 to rotate through the transmission block 3. The lock body realizes the function of outward opening. When the restriction on the transmission block 3 is released, the locking plate 16 can be reset under the action of the rebound force of the torsion spring 17. The other ends of the two pull wires can be set on the car door, which is convenient for the user to manually pull the two pull wires.
