Specifically, the lock body 1 includes a rotating part 11, a support plate 10, a limit block 13 and two side walls 16. The rotating part 11, the support plate 10, the limit block 13 and the two side walls 16 are an integrally formed structure. The rotating part 11 and the limit block 13 are respectively arranged at both ends of the length direction of the lock body 1, and the two side walls 16 are arranged at the width of the lock body 1. On both sides of the direction, the support plate 10 is located inside the lock body 1 and is connected to the rotating part 11 and the two side walls 16, so that the rotating part 11, the support plate 10, the limit block 13 and the two side walls 16 together form a receiving groove 2 structure, the bottom of the receiving groove 2 structure is hollow, and a lock component 3 is arranged in the receiving groove 2. The length of the lock component 3 is smaller than the length of the receiving groove 2, but the overall size is larger than the hollow hole at the bottom of the receiving groove 2, so that the entire lock component 3 can be embedded in the receiving groove 2 without falling off.

[0026] The locking member 3 is provided with a step, which cooperates with the support plate 10 , so that the locking member 3 can slide on the support plate 10 of the accommodating groove 2 .

[0027] like Figure 3 and Figure 3 As shown in the orientation, the step of the lock member 3 is arranged on the left side, and a hook portion 12 is arranged on the right side of the lock member 3. The lower surface of the lock member 3 is flush with the bottom of the support plate 10, and a rack structure 4 is arranged on the upper right side of the lock member 3. A lever 5 structure is also rotatably connected to the two side walls 16 of the lock body 1. Specifically, the lever 5 structure is a plate-shaped structure, and the left end of the lever 5 is a rotating shaft head 9, and a gear structure 6 is arranged on the rotating shaft head 9. When the lever 5 is in the horizontal state shown in the figure, the gear structure 6 is only distributed inside the lock body 1, and the rest of the position of the rotating shaft head 9 is a smooth structure.

[0028] When lever 5 is Figure 3 When rotating counterclockwise as shown, the gear structure 6 on the shaft head 9 will drive the rack structure 4 on the locking member 3 to move to the right, so that the step on the locking member 3 is separated from the support plate 10, and the locking member 3 as a whole moves to the right on the support plate 10 of the accommodating groove 2, so that the position of the hook 12 moves to the right, and the hook 12 will disengage from the lock port 21, thereby completing the unlocking action of the locking member 3.

[0029] like Figure 5As shown, the rotating part 11 of the lock body 1 is provided with a shaft hole 11.1, and the lock body 1 can be fixed on the box as a whole through the shaft hole 11.1. The box includes a box cover 17 and a box body 18. The outside of the box cover 17 is provided with a bayonet 19, and the outside of the box body 18 is provided with a matching piece 20 at a position corresponding to the bayonet 19. The matching piece 20 includes a protrusion 20.1 and a locking plate 20.2. The protrusion 20.1 can cooperate with the bayonet 16 to realize the locking function. A locking hole 21 is formed between the locking plate 20.2 and the box body 18. The locking hole 21 can cooperate with the hook part 12, so that the hook part 12 can fix the protrusion 20.1 and the bayonet 19 together to prevent the protrusion 20.1 and the bayonet 19 from loosening. Specifically, as shown in FIG. Figure 5 In the shown position, when the lever 5 is rotated counterclockwise, the gear structure 6 on the lever 5 drives the rack structure 4 on the lock member 3 to move, so that the lock member 3 moves downward as a whole, the groove on the hook 12 is separated from the lock plate 20.2, the hook 12 is separated from the lock port 21, and then the rotating part 11 can be rotated to rotate the entire lock body 1 counterclockwise, so that the lock member 3 is separated from the box body 18, and the box cover 17 can be opened at this time; on the contrary, when the box cover 17 needs to be closed and locked, it is only necessary to rotate the rotating part 11 in the opposite direction so that the lock member 3 is close to the box body 18, and then the lever 5 is rotated in the opposite direction to make the hook 12 and the lock port 21 match again, and the locking operation is completed.

[0030] It should also be noted that a packaging cover 7 is also provided on the lock body 1. The packaging cover 7 is provided on the receiving groove 2 and is used to package the lock member 3 in the receiving groove 2.

The reset member 14 specifically adopts a spring structure, one end of the spring is fixed to the rotating part 11, and the other end is fixed to the lock member 3. When the lever 5 is moved to drive the lock member 3 to move to the right, the lock will be unlocked, and the spring is also stretched. When the force of the lever 5 disappears, the spring has a retraction force under the action of stretching, and resets the lock member 3, thereby ensuring that the lever 5 can return to the initial position in time, preventing the lever 5 from being pulled out and damaged by the external environment. In addition, the reset member 14 can improve the locking effect of the lock. After long-term use, the rotation damping force of the lever 5 is reduced, and the lever 5 is easy to loosen. The reset member 14 can pull the lock member 3 to the left to ensure that the protrusion 20.1 on the box body 18 and the bayonet 19 are tightly matched.
