[0029] In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, the meaning of "multiple" or "several" is two or more, unless otherwise specifically defined.

[0030] Please refer to Figures 1-6 As shown, the purpose of this embodiment is to provide a foam packing box for preventing the lid from shifting, including a lid 1 and a box body 2.

[0031] Furthermore, a magic tape assembly 7 is provided on one side of the top end of the box body 2. The box body 2 is connected to the lid 1 through the magic tape assembly 7. A first card slot 8 is opened at the top end of the lid 1. A first sliding groove 4 is opened in the first card slot 8. A second sliding groove 5 corresponding to the first sliding groove 4 is opened on one side of the box body 2. A second card slot 3 is opened at the bottom end of the box body 2. A fixing rod assembly 6 is detachably arranged in the first sliding groove 4 and the second sliding groove 5. The lid 1 and the box body 2 are detachably connected through the fixing rod assembly 6.

[0032] Furthermore, the fixed rod assembly 6 includes a connecting rod 61. The length of the connecting rod 61 is matched with the distance from the first card slot 8 on the box cover 1 to the second card slot 3 at the bottom end of the box body 2. A lower stop rod 62 is fixedly connected to the bottom end of the connecting rod 61, and an upper stop rod 63 is fixedly connected to the top end of the connecting rod 61. An installation groove 64 is also formed at the top end of the connecting rod 61. A lifting block 65 is threadedly connected in the installation groove 64, and the lifting block 65 is detachably connected to the installation groove 64. When the lower stop rod 62 reaches into the second card slot 3, align the lifting block 65 with the installation groove 64 for installation. It should be noted that the installation direction of the lifting block 65 and the installation groove 64 is opposite to the counterclockwise fixing direction of the upper stop rod 63. Then rotate the lifting block 65 so that the upper stop rod 63 and the lower stop rod 62 are turned to the middle position between the first card slot 8 and the second card slot 3, which can better fix the box cover 1 and the box body 2. Moreover, the length of the lower stop rod 62 should be at least half of the width of the box body 2. The main function of the lifting block 65 is to facilitate pulling out the fixed rod assembly 6 from the first sliding groove 4 and the second sliding groove 5. It is also possible to manually rotate the upper stop rod 63 and the lower stop rod 62.

[0033] Specifically, the magic tape assembly 7 includes a fixed tape 71, which is fixedly connected to the outer wall of one side of the box body 2. A lower magic tape 72 is arranged at the top end of the box body 2 on the same side as the fixed tape 71. The top end of the lower magic tape 72 is a hairy surface, and the bottom end is a smooth surface. An upper magic tape 73 is fixedly connected to the bottom end of the box cover 1 on the same side as the lower magic tape 72. The bottom end of the upper magic tape 73 is a hook surface, and the top end is fixedly connected to the box cover 1. One side of the lower magic tape 72 is fixedly connected to the fixed tape 71. In this way, the bottom end of the lower magic tape 72 is movably connected to the box body 2, and it is only fixedly connected to the fixed tape 71 on one side. However, the lower magic tape 72 is initially attached to the top end of the box body 2, so that the hairy surface at its top end can be adhered to the hook surface at the bottom end of the upper magic tape 73, which can not only connect the box cover 1 and the box body 2, but also be disassembled. And by setting the low-cost magic tape like this, it is realized that the box cover 1 and the box body 2 are rotatably connected on the same side.

[0034] Further, both the first card slot 8 and the second card slot 3 are fan-shaped structures, and the radius of the first card slot 8 is matched with the length of the lower stop rod 62, and the radius of the second card slot 3 is matched with the radius of the upper stop rod 63.

[0035] In addition, the lengths of the first sliding groove 4 and the second sliding groove 5 are both matched with the length of the lower stop rod 62.

[0036] In addition, a placement groove 9 is also formed in the first card slot 8 for placing the lifting block 65. After the lifting block 65 is placed in the placement groove 9, its height does not exceed the upper surface of the box cover 1.

[0037] The specific working principle is as follows:

[0038] During specific operation, align and cover the box cover 1 with the box body 2 so that the upper magic tape 73 fits with the lower magic tape 72 on the box body 2. Then, align the lower stop bar 62 in the fixing rod assembly 6 and press it against the first chute 4. The fixing rod assembly 6 reaches the second card slot 3 after passing through the first chute 4 and the second chute 5. At this time, the upper stop bar 63 reaches the first card slot 8. Then rotate the upper stop bar 63 so that the upper stop bar 63 and the lower stop bar 62 respectively rotate to the middle positions in the first card slot 8 and the second card slot 3, which is convenient for fixing the box cover 1 and the box body 2. Then, place the lifting block 65 into the placement groove 9. In this way, when it is necessary to open the box cover 1, take out the lifting block 65 and install it into the installation groove 64 at the top of the connecting rod 61. Then rotate the upper stop bar 63 to make it flush with the first chute 4. In this way, the lower stop bar 62 is also aligned with the second chute 5. Then, the entire fixing rod assembly 6 can be lifted by the lifting block 65. After removing the fixing rod assembly 6, the box cover 1 can be opened. At this time, the magic tape assembly 7 acts as a hinge between the box cover 1 and the box body 2; thus effectively solving the problem that the box cover of the existing foam packaging box is prone to offset during transportation.
