[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 4 As shown, the utility model provides a double-layer packaging box, comprising:

[0024] Box body 1;

[0025] The left and right sides of the top of the box body 1 are both plugged with fixing columns 2, the top of the fixing columns 2 is fixedly connected with a cover plate 3, and the left and right sides of the bottom of the inner wall of the box body 1 are both fixedly connected with a connecting mechanism 4;

[0026] The connecting mechanism 4 includes a partition 41, a slider 42, a support plate 43, an iron sheet 44 and a magnet 45. The partition 41 is fixedly connected to the left and right sides of the bottom of the inner wall of the box body 1. The back end of the top of the partition 41 is slidably connected to the slider 42. The top of the slider 42 is fixedly connected to the support plate 43. The front end of the support plate 43 passes through the front end of the box body 1. The back end of the support plate 43 is fixedly connected to the iron sheet 44. A magnet 45 is arranged at the back end of the inner wall of the box body 1 and at the position corresponding to the iron sheet 44. The iron sheet 44 is in contact with the front end of the magnet 45.

[0027] refer to Figure 3 A receiving groove 5 is provided on the surface of the support plate 43 , and the receiving groove 5 is used in conjunction with the support plate 43 .

[0028] As a technical optimization solution of the present invention, the arrangement of the receiving groove 5 can assist the support plate 43 in working, thereby avoiding the situation where the surface of the support plate 43 is too smooth to accommodate goods.

[0029] refer to Figure 1 The front end of the support plate 43 is fixedly connected with a handle 6 , and the handle 6 is used in conjunction with the support plate 43 .

[0030] As a technical optimization solution of the present invention, the handle 6 can assist the support plate 43 in working and play a fixing role at the same time, thereby avoiding the support plate 43 having no force points during operation.

[0031] refer to Figure 2 A slide groove 7 is provided on the top of the partition plate 41 , and the slide groove 7 is used in conjunction with the slider 42 .

[0032] As a technical optimization solution of the present invention, the slide groove 7 can assist the slider 42 in working and play a role of limiting, thereby avoiding the slider 42 from deviating during the movement.

[0033] refer to Figure 4 The bottom of the cover plate 3 is fixedly connected with a heat-insulating layer 8 , and the heat-insulating layer 8 is used in conjunction with the cover plate 3 .

[0034] As a technical optimization solution of the utility model, the setting of the thermal insulation layer 8 can assist the cover plate 3 in working and play a role of thermal insulation, thereby avoiding the problem that the cover plate 3 cannot retain heat and the inside of the box body 1 cannot be thermally insulated.

[0035] refer to Figure 1 The left and right sides of the top of the box body 1 and the positions corresponding to the fixing columns 2 are provided with grooves 9 , and the grooves 9 are used in conjunction with the fixing columns 2 .

[0036] As a technical optimization solution of the utility model, the setting of the groove 9 can assist the fixing column 2 in working and play a limiting role, thereby avoiding the phenomenon that the fixing column 2 is stuck in the groove 9 due to the width of the groove 9 being too narrow.

[0037] The working principle and use process of the utility model are as follows: when in use, hold the support plate 43 to align the slider 42 with the slide groove 7, move backward along the partition 41, and move the support plate 43 backward to make the iron sheet 44 contact the magnet 45. The magnet 45 fixes the position of the support plate 43 due to the adsorption characteristics, and then hold the cover plate 3 to align the fixing column 2 with the groove 9 and insert it. The cover plate 3 covers the surface of the box body 1 to complete the assembly. Similarly, when disassembling, pull the handle 6 forward to force the iron sheet 44 to separate from the magnet 45 and drive the slider 42 to move forward from the inside of the box body 1, and then pull the cover plate 3 vertically upward to make the fixing column 2 separate from the groove 9 and disassemble the whole body to achieve the splicing and assembly function.

[0038] In summary: the double-layer packaging box, through the coordinated use of the box body 1, the fixing column 2, the cover plate 3, the connecting mechanism 4, the partition 41, the slider 42, the support plate 43, the iron sheet 44 and the magnet 45, solves the problem that most of the existing packaging boxes are an integral whole and cannot be assembled, disassembled or combined.
