[0018] The following further describes the technical solution of the present utility model in detail with reference to the preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figure 1-3, the present utility model provides a technical solution: a folding box with a locking function, including a support plate 1. The top of the support plate 1 is connected to a first folding plate 2 through a hinge. The top of the first folding plate 2 is connected to a second folding plate 3 through a hinge. The top of the second folding plate 3 is connected to a frame 4 through a hinge. Both ends of the frame 4 are connected to side plates 5 through hinges. The inner wall of the frame 4 is connected to two cover plates 6 through hinges. Fixed shafts 7 and positioning blocks 8 are respectively fixedly connected to the outer walls of the two cover plates 6. A limiting block 9 is fixedly connected to the top of the fixed shaft 7. A volute spring 10 is fixedly connected to the outer wall of the fixed shaft 7. A movable block 11 is fixedly connected to the outer wall of the volute spring 10. A dial block 12 is fixedly connected to one side of the movable block 11. A hook 13 is fixedly connected to the other side of the movable block 11. By providing the support plate 1, the first folding plate 2, the second folding plate 3, the frame 4, the side plates 5, the cover plates 6, the fixed shafts 7, the positioning blocks 8, the limiting blocks 9, the volute springs 10, the movable blocks 11, the dial blocks 12 and the hooks 13, the functions of quick locking and quick unlocking are realized, thereby improving the convenience of operation, solving the time-consuming and laborious problem caused by cumbersome operation, meeting the work needs of people, and being worthy of popularization and use.

[0020] Furthermore, the fixed shaft 7 and the limiting block 9 are distributed in a "T" shape, and the diameter of the limiting block 9 is larger than that of the movable block 11, which facilitates the limitation of the movable block 11.

[0021] Furthermore, the movable block 11 is in an annular structure, and the movable block 11 and the fixed shaft 7 form a rotating structure through the volute spring 10, which facilitates the reset rotation of the movable block 11.

[0022] Furthermore, the dial block 12 is in a hook shape, and the dial block 12 and the movable block 11 are integrally arranged, which facilitates the rotation of the movable block 11 by拨动 the dial block 12.

[0023] Furthermore, the hook 13 is in a hook shape, and the orientation of the hook 13 is opposite to that of the dial block 12, which facilitates the positioning work through the hook 13.

[0024] Furthermore, the hook 13 and the positioning block 8 are engaged with each other, and the positioning block 8 is in a "soil" shape structure, which facilitates the positioning of the hook 13.

[0025] When in use, first, the shift block 12 is rotated, so that the shift block 12 drives the hook 13 to rotate through the movable block 11, and then the hook 13 is separated from the positioning block 8, and then the two cover plates 6 are unlocked, thereby facilitating the two cover plates 6 to be rotated and opened through the hinges. When the movable block 11 rotates, the spiral spring 10 is deformed. Later, when the two cover plates 6 are merged, the movable block 11 is driven to reset and rotate through the elasticity of the spiral spring 10, so that the movable block 11 drives the hook 13 to reset and rotate and then engage with the positioning block 8, thereby realizing the function of automatic locking, improving the convenience of operation, and solving the problem of easy loosening.
