In the embodiment of the utility model, the first baffle 2 and the second baffle 3 are respectively clamped at the four corners of the packing box, and cooperate with the first plug plate 4 and the second plug plate 5 to fix the four corners of the packing box through the corner clip. In the embodiment of the utility model, the first plug plate 4 and the second plug plate 5 are respectively plug-in connected with the slots on the cross beam of the packaging box, the first clamping platform 6 and the second clamping platform 7 respectively arranged on the first baffle plate 2 and the second baffle plate 3 are respectively clamped and connected with the lower edge of the cross beam of the packaging box, and the corner clamping surface 1 is fit-connected with the upper surface of the cross beam of the packaging box. This design enables the corner clamps to better fix the four corners of the packaging box, effectively preventing the box from shaking and deforming during transportation, thereby greatly improving the overall stability of the packaging box.

[0025] The first baffle plate 2 and the second baffle plate 3 are respectively provided with a stamping groove 11, and the stamping groove 11 is concave outward. The first clamping platform 6 and the second clamping platform 7 are respectively divided into two groups, and the first clamping platform 6 and the second clamping platform 7 are respectively arranged on both sides of the stamping groove 11. In the embodiment of the utility model, the stamping groove 11 is respectively provided on the first baffle plate 2 and the second baffle plate 3, and the stamping groove 11 can not only enhance the strength of the baffle plate, but also enhance the connection strength between the corner clamp and the packaging box through the connection of the stamping groove 11 and the protrusion structure on the cross beam of the packaging box. In the embodiment of the utility model, the first baffle plate 2 and the second baffle plate 3 are connected by welding, which significantly enhances the rigidity and overall stability of the corner clamp, and can effectively prevent the corner clamp from being deformed or damaged due to external force during transportation and stacking, thereby improving the overall pressure resistance and durability of the packaging box.

[0026] Long holes 12 are respectively provided on both sides of the punching groove 11 , and the long holes 12 correspond to the positions of the first clamping platform 6 and the second clamping platform 7 respectively.

[0027] The first card platform 6 and the second card platform 7 are elastic card plates, one end of the first card platform 6 and the second card platform 7 are connected to the end of the first baffle 2 and the second baffle 3 respectively, and the other end of the first card platform 6 and the second card platform 7 is inclined to extend from the box corner card surface 1. In the embodiment of the utility model, the first card platform 6 and the second card platform 7 are made of elastic card plates, and the ends of the first card platform 6 and the second card platform 7 are connected to the ends of the first baffle 2 and the second baffle 3 respectively, and can be fixedly connected by welding, or can be made by bending and forming with the baffle as a whole. The first card platform 6 and the second card platform 7 extend inwardly in the direction of the corner card surface 1. When the corner card is connected to the four corners of the packaging box, the first card platform 6 and the second card platform 7 are respectively clamped on the lower edge of the cross beam of the packaging box. Since there is a certain angle between the first card platform 6 and the second card platform 7 and the baffle, it can be conveniently clamped with the lower edge of the cross beam of the packaging box. When the corner card needs to be removed, the first card platform 6 or the second card platform 7 is pried to separate from the lower edge of the cross beam of the packaging box, and then the corner card can be removed. Since the first clamping platform 6 and the second clamping platform 7 have a processing thickness, a long hole 12 is set at the relative position of the first clamping platform 6 and the second clamping platform 7. The width and length of the long hole 12 are slightly larger than the size of the clamping platform. Therefore, when installing the corner clamp, the packaging box beam squeezes the clamping platform, and the clamping platform is bent into the long hole 12, and the space of the long hole 12 is utilized without affecting the insertion space between the beam and the corner clamp. In the embodiment of the utility model, the thickness of the first clamping platform 6 and the second clamping platform 7 is not greater than the depth of the long hole 12.

[0028] A plurality of spring plates 13 are disposed on the corner clamping surface 1 , and the positions of the spring plates 13 correspond to the positions of the stamping grooves 11 .

[0029] The first clamping platform 6 and the second clamping platform 7 respectively include a long plate and a boss, and the inner side of the long plate is connected to the boss in an arc transition. In the embodiment of the utility model, the inner side end surfaces of the first clamping platform 6 and the second clamping platform 7 adopt an arc transition to facilitate the clamping and matching connection between the clamping platform and the lower edge of the cross beam of the packaging box.

[0030] An L-plate 16 is provided on one side of each of the first clamping platform 6 and the second clamping platform 7. The L-plate 16 extends into the long hole 12 and is bent toward the end.

[0031] The lengths of the first plug board 4 and the second plug board 5 are 20 mm to 30 mm respectively, the widths of the first plug board 4 and the second plug board 5 are 10 mm to 30 mm respectively, and the ends of the first plug board 4 and the second plug board 5 are provided with chamfers or rounded corners.

[0032] The corner clamping surface 1, the first baffle plate 2 and the second baffle plate 3 are made of tinplate, and the thickness of the corner clamping surface 1, the first baffle plate 2 and the second baffle plate 3 are 0.8 mm to 2 mm respectively.

[0033] Of course, the above embodiments are not intended to limit the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
