A plastic packaging box

Abstract

The invention relates to the technical field of plastic packaging boxes, specifically a plastic packaging box, including a plastic box, a top cover, a collision mechanism, a first pull rod, a second pull rod, a stop rod, a rotating shaft, a telescopic spring, a slide rod, and a fixed shaft , card slot and adjustment mechanism. In the present invention, by pulling the two stop rods, the distance between the second pull rod and the second pull rod is stretched under the action of the slide rod and the telescopic spring, and when it is rotated to a certain position, the slots on one side of the two stop rods are aligned. The corners at both ends of the top of the push rod are removed, and the pulling force is removed, so that the first pull rod and the second pull rod shrink under the action of the telescopic spring, so that the inside of the card slot on one side of the two stop rods is in contact with the top corner of the top cover, so that Two blocking rods lock the top cover to prevent easy opening or falling off. Under the action of two sets of first and second rods, it is beneficial to close and support the plastic box, which plays the role of anti-drop and compression resistance. The function of the regulating mechanism is conducive to regulating the ventilation inside the plastic box.

Description

technical field [0001] The invention relates to the technical field of plastic packaging boxes, in particular to a plastic packaging box. Background technique [0002] Plastic is a high molecular compound polymerized by addition polymerization or polycondensation reaction with monomer as raw material. It has medium resistance to deformation and is between fiber and rubber. The main component of plastic is resin. Resin refers to a polymer compound that has not been mixed with various additives. The term resin was originally named after the lipids secreted by animals and plants, such as rosin, shellac, etc. The basic properties of plastics are mainly determined by the nature of the resin. But additives also play an important role. Some plastics are basically composed of synthetic resins with no or little additives, such as plexiglass and polystyrene.

Problems solved by technology

[0003] Plastic packaging boxes can be seen everywhere in daily life production, which is conducive to placing different items. It is light and beautiful. However, the traditional plastic packaging box directly buckles the top cover and the box body, which is easy to loosen. At the same time, when dealing with fragile and pressure-resistant items, the pressure resistance is low, and it is easy to cause the items to fall when shaking
