[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will combine the accompanying drawings of the embodiments of the present utility model Figures 1-6 to clearly and completely describe the technical solutions of the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by the present utility model.

[0032] As Figures 1-6 shown: This embodiment provides a stackable plastic packing box, including a box body 100 and a box cover 200, and the box body 100 and the box cover 200 are connected together through a connection structure;

[0033] The box body 100 includes a bottom plate 101, the cross-section of the bottom plate 101 is a square structure, and a support frame 102 is fixedly provided on the bottom plate 101, and a plastic mesh plate is arranged on the support frame 102;

[0034] The support frame 102 includes four support plates 103, the four support plates 103 are connected end to end and are fixedly arranged on the bottom plate 101 in a rectangular structure, the cross-section of the support plate 103 is a rectangular frame structure, and the plastic mesh plate is arranged inside the rectangular frame, that is, the support plate 103 with a rectangular frame cross-section can save support materials;

[0035] And four strengthening blocks 105 are also arranged inside the support plate 103, the four strengthening blocks 105 are respectively located at the four corner positions of the support plate 103, and the strengthening blocks 105 can strengthen the structural rigidity at the corners of the support plate 103, thereby indirectly increasing the structural strength of the support frame 102.

[0036] The bottom of the bottom plate 101 is also provided with four positioning grooves 104. The four positioning grooves 104 are all strip-shaped structures and are located at the midline positions of the four sides of the bottom plate 101;

[0037] The cross-section of the box cover 200 is the same as that of the bottom plate 101, and two positioning plates 201 corresponding to the positioning grooves 104 are further provided on the upper surface of the box cover 200. The two positioning plates 201 are symmetrically arranged on both sides of the box cover 200;

[0038] The positioning plate 201 can be inserted into the positioning groove 104 on the bottom plate 101, so that multiple plastic packaging boxes can be stacked vertically together. The cooperation between the positioning groove 104 and the positioning plate 201 can prevent the plastic packaging boxes from falling easily, thereby reducing the probability of damage to the packaging boxes during transportation.

[0039] The connection structure is as Figure 1 、 2 、4, 5, 6 shown,

[0040] The connection structure includes four through holes 300 vertically arranged at the top of the support frame 102. The four through holes 300 are respectively located at the four corner positions of the top of the support frame 102. Corresponding to the through holes 300, movable holes 301 are provided on the support frame 102. The movable holes 301 are communicated with the through holes 300, and the cross-sectional area of the movable holes 301 is larger than the cross-sectional area of the through holes 300;

[0041] The connection structure further includes a rotating rod 302 vertically arranged on the box cover 200 through a bearing. The rotating rod 302 is located above the through hole 300, and the rotating rod 302 can be inserted into the through hole 300. A movable block 303 is provided at the bottom end of the rotating rod 302 corresponding to the movable hole 301, and the movable block 303 can also be inserted into the through hole 300; The cross-sections of the through hole 300 and the movable block 303 are both rectangular structures; that is, the cross-sections of the through hole 300 and the movable block 303 are the same and the cross-sectional area of the movable block 303 is smaller than the cross-sectional area of the through hole 300;

[0042] The cross-section of the movable hole is a circular structure, and the diameter of the movable hole is longer than the side length of the longest side of the through hole. Thus, the movable block can rotate after entering the movable hole.

[0043] When fixing the box cover 200, the box cover 200 is placed above the box body 100 and then placed downward. The box cover 200 moves downward, so that the movable block 303 can pass through the through-hole 300 and enter the movable hole 301. Then, the rotating rod 302 is slightly rotated, and the rotating rod 302 can rotate with the movable block 303. After the movable block 303 rotates, the position is offset, and the through-hole 300 can limit the movable block 303, so that the box cover 200 cannot be removed from the box body 100. When the box cover 200 needs to be removed, the rotating rod 302 is rotated to indirectly make the movable block 303 pass through the through-hole 300, so that the box cover 200 can be removed from the box body 100.

[0044] Chuck 304 Figure 5 As shown,

[0045] A storage slot 202 is provided on the box cover 200 corresponding to the rotating rod 302, and a chuck 304 is provided on the end of the rotating rod 302 away from the movable block 303, and a clamping strip 305 is provided on the upper surface of the chuck 304, that is, by toggling the clamping strip 305, the rotating rod 302 and the movable block 303 can be indirectly rotated, and the storage slot 202 can accommodate the chuck 304 and the clamping strip 305, so that the chuck 304 and the clamping strip 305 will not affect the stacking between multiple plastic packaging boxes.

[0046] Force hole 203 Figure 4 As shown,

[0047] The positioning plate 201 is provided with a force hole 203 ; that is, the force hole 203 facilitates the application of force to the positioning plate 201 , and the arrangement of the force hole 203 on the positioning plate 201 does not affect the stacking of multiple plastic packaging boxes and can also save materials.

[0048] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
