[0013] Preferably, the box body is integrally formed by folding cardboard, which is convenient for processing and production. There is no need to use glue or other adhesives, which is both environmentally friendly and saves materials.

[0014] Compared with the related technology, the present utility model has the following beneficial effects:

[0015] 1. The packaging box is integrally formed by folding cardboard, without using glue or other adhesives, which reduces the emission of harmful substances from the source and meets the requirements of modern environmental protection. At the same time, its reduction design effectively reduces material consumption, reduces the burden of treating packaging waste, and has a positive significance for environmental protection.

[0016] 2. Since the packaging box adopts a simple folding structure and an insertion locking mechanism, the production process of the packaging box is relatively simple, which reduces the production cost. In addition, its reduction design also reduces the material usage, further reducing the overall cost, making the packaging box more competitive in price in the market.

[0017] 3. The left and right sides adopt a double-layer structure to enhance the compressive strength of the paper box.

Detailed implementation mode

[0022] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] The glue-free weight-reduced part packaging box has a box body;

[0024] As Figures 1 to 3 shown, the box body includes a box bottom 1, a front end face 2 connected to the lower edge of the box bottom 1, a rear end face 3 connected to the upper edge of the box bottom 1, a box cover 4 connected to the upper edge of the rear end face 3, outer side walls 6 are connected to both sides of the front end face 2, insertion pieces 7 are provided at the edges of the outer side walls 6, inner side walls 5 are connected to both sides of the rear end face 3, slots 8 are provided at the connection between the inner side walls 5 and the rear end face 3, and the insertion pieces 7 can be inserted into the corresponding slots 8 inside after folding, a insertion tongue 12 is provided at the lower edge of the front end face 2, a dust-proof wing 10 is connected to the upper edge of the box cover 4, a jack 11 is provided at the connection between the dust-proof wing 10 and the box cover 4, and the insertion tongue 12 can be inserted into the jack 11 after folding.

[0025] During the folding process, the box bottom 1 serves as the bottom support, the front end face 2 is located in the front, the rear end face 3 is located in the rear, the inner side walls 5 are located on both sides inside the box body, and the outer side walls 6 are located on both sides outside the box body. Through precise folding design, each component is tightly connected to form a stable box body structure;

[0026] When the packaging box is in the unfolded state, the insertion pieces 7 at the edges of the outer side walls 6 can be inserted into the slots 8 on the inner side walls 5 on both sides of the rear end face 3 through bending to achieve stable connection of the side walls. At the same time, the insertion tongue 12 at the lower edge of the front end face 2 can be inserted into the jack 11 of the dust-proof wing 10 at the upper edge of the box cover 4 after folding, further enhancing the connection stability between the box body and the box cover 4;

[0027] The box cover 4 is tightly connected to the box body through the dust-proof wings 10 at its edges. The dust-proof wings 10 not only play a dust-proof role, but also realize the preliminary locking of the box cover 4 through the cooperation of the jack 11 and the insertion tongue 12.

[0028] As Figures 1 to 3 shown, an inner tongue plate 14 that can be bent is provided at the connection between the box cover 4 and the dust-proof wing 10, a strip hole 13 is provided at the connection between the insertion tongue 12 and the front end face 2, and the inner tongue plate 14 can be inserted into the strip hole 13 after folding;

[0029] There is a bendable inner tongue plate 14 at the connection between the box cover 4 and the dust-proof wing 10. When the box cover 4 is closed, the inner tongue plate 14 can be inserted into the strip hole 13 on the front end face 2 to lock the box cover 4 again, ensuring the sealing and stability of the packaging box.

[0030] As Figures 1 to 3 shown, sector-shaped pieces 9 are connected to both sides of the box cover 4. The sector-shaped pieces 9 connected to both sides of the box cover 4 play an important role during the use of the packaging box. When the box cover 4 is closed, the sector-shaped pieces 9 are bent and embedded inside the box body along with the box cover 4, without occupying extra space. When the box cover 4 needs to be opened, the sector-shaped pieces 9 can serve as a guide to make the opening of the box cover 4 smoother.

[0031] As Figures 1 to 3 shown, the length of the rear end face 3 is the same as that of the box bottom 1, the length of the box cover 4 is less than that of the box bottom 1, and the length of the front end face 2 is greater than that of the box bottom 1, so that the outer side wall 6 of the bent front end face 2 can be located outside the inner side wall 5.

[0032] As Figures 1 to 3 shown, a small part of the insertion piece 7 close to the outer side wall 6 has a width that gradually decreases along the direction close to the outer side wall 6, reducing the resistance during insertion. At the same time, this design also helps to improve the connection strength between the insertion piece 7 and the slot 8, preventing it from falling off due to external forces during transportation or use.

[0033] As Figures 1 to 3 shown, a protrusion extends outward from a corner of the sector-shaped piece 9. The protrusion causes the sector-shaped piece 9 to have a squeezing contact with the inner wall of the box body during the opening process of the box cover 4, thereby helping the box cover 4 to stay at the angle desired by the user, facilitating the taking and placing of parts or performing other operations.

[0034] As Figures 1 to 3 shown, the box body is integrally formed by folding cardboard, without the use of glue or other adhesives, which is both environmentally friendly and material-saving.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
