[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] Example 1

[0027] As attached Figure 5 As shown, a packaging carton with an anti-deformation function includes a box body 1 and a box cover 2. The box body 1 and the box cover 2 are both made of multi-layer corrugated cardboard with a thickness of 8 to 15 mm. The multi-layer corrugated cardboard box body 1 and the box cover 2 themselves have good supporting hardness;

[0028] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 As shown, arc-shaped support frames 3 are respectively installed at the four corners of the inner wall of the box body 1, and connecting pipes 4 are inserted between the arc-shaped support frames 3 and the inner corners of the box body 1. Multiple groups of protective pipes 5 are inserted and connected between the multiple groups of connecting pipes 4. The side walls of the connecting pipes 4 are provided with multiple groups of jacks 6 for inserting the protective pipes 5, and the side walls of the arc-shaped support frames 3 are provided with through holes 7 for the protective pipes 5 to pass through. The connecting pipes 4 and the protective pipes 5 are both made of PE material, which is light and has good corrosion resistance.

[0029] Through the above structure, the arc-shaped support frame 3 is installed at the four corners of the inner wall of the box body 1, the connecting pipe 4 is inserted between the arc-shaped support frame 3 and the inner corner of the box body 1, the connecting pipe 4 is rotated, the socket 6 is aligned with the through hole 7, and the two ends of the tough protective tube 5 are respectively passed through the through hole 7 and inserted into the socket 6, and multiple groups of protective tubes 5 are installed. When the side wall of the box body 1 is squeezed, the side wall of the box body 1 is supported by the multiple groups of protective tubes 5 to prevent the side wall of the box body 1 from being squeezed and deformed. The four corners of the box body 1 are supported by the connecting pipe 4 to improve the support of the box body 1 for the heavy objects on the upper side.

[0030] Combined with attachment Figure 4 As shown, both sides of the arc-shaped support frame 3 are integrally formed with folding edges 8 connected to the box body 1, and the folding edges 8 are connected to the box body 1 with glue or staples.

[0031] Through the above structure, the folded edge 8 is connected to the box body 1 by means of glue or staples, so that the arc-shaped support frame 3 is fixedly installed on the inner sides of the four corners of the box body 1.

[0032] Example 2

[0033] Based on the first embodiment, please refer to the attached Figure 5 and attached Figure 6 The box cover 2 is sleeved on the outside of the top of the box body 1, and multiple groups of reinforcing rods 9 are installed on the inner wall of the top. The reinforcing rods 9 are made of PE material and are bonded to the inner wall of the top of the box cover 2. Multiple groups of grooves 10 for matching the reinforcing rods 9 are respectively provided on the upper edges of the two side walls of the box body 1.

[0034] Through the above structure of Example 2, the reinforcing rod 9 is supported in the groove 10 on the upper side of the two side walls of the box body 1, so that the two ends of the reinforcing rod 9 have good support, thereby improving the support of the reinforcing rod 9 on the box cover 2, and also allowing the top inner wall of the box cover 2 to contact the upper side of the side wall of the box body 1, preventing the items inside the packaging carton from falling out.
