Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a foam packaging box with an anti-extrusion structure. Background Art

[0002] Foam packaging is a box-like packaging container made from a plastic-based polymer material containing numerous air bubbles. Its numerous tiny pores make it lightweight, heat-insulating, sound-insulating, and shock-resistant. Foam packaging is commonly used for transporting and packaging fruits, vegetables, and fresh food, and is also widely used in industry, agriculture, construction, and transportation. Foam packaging comes in a variety of types, including polyurethane, polystyrene, polyvinyl chloride, polyethylene, and phenolic resin. Its production process is simple, requiring no special processing or chemical additives, and it is recyclable after use, meeting environmental protection requirements.

[0003] According to the Chinese patent publication number CN216762747U, a new EPS foam packaging box includes a container body, the lower end of which is provided with a handheld assembly. The handheld assembly includes a support body, which is respectively connected to the four end corners of the bottom of the container body. The tops of the four support bodies are fixedly connected to load-bearing rods, and the sides of the support bodies are connected to reinforcing ribs. The reinforcing ribs and the top of the container body form a handheld area. The surface of the round rod is detachably connected to a clamp ring, and the interior of the clamp ring is provided with a bayonet, and the interior of the bayonet is provided with an adjustment cover. The support body is a cylindrical rod with a domed bottom, and the height of the support body is at least five centimeters. The reinforcing rib is an X-shaped rod-shaped component, and the top of the reinforcing rib is in contact with the bottom of the container body.

[0004] In the above solution, ventilation holes are used to ventilate the interior of the container body, but it still has the following disadvantages: due to the presence of the ventilation holes, a cavity exists on the inner wall of the foam box. When the cavity part of the foam box is subjected to squeezing force, the foam packaging box may be damaged due to insufficient bearing capacity. Utility Model Content

[0005] The purpose of the utility model is to provide a foam packaging box with an anti-extrusion structure to solve the problem that when the cavity portion of the foam box is subjected to an extrusion force, the foam packaging box may be damaged due to insufficient bearing capacity.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical solutions: a foam packaging box with an anti-extrusion structure, comprising a packaging box shell, a fixing frame is fixed on the top surface of the packaging box shell, a cover is detachably provided on the top surface of the fixing frame, a plurality of mounting grooves are opened on the top surface of the packaging box shell, a reinforcing bent plate is fixed inside the mounting groove, a bottom plate is fixed on the inner bottom surface of the packaging box shell, a main binding belt is fixed on the top surface of the bottom plate, and a secondary binding belt is fixed on the top surface of the bottom plate.

[0007] Preferably, a Velcro hook surface is fixed to the bottom surface of the primary binding belt, and a Velcro fleece surface is fixed to the top surface of the secondary binding belt.

[0008] Preferably, a wrapping belt is wrapped around the surface of the packaging box shell, mounting plates are fixed on both sides of the wrapping belt, a limiting belt is rotatably provided on the mounting plate, rotating columns are fixed on both sides of the mounting plate, rotating holes are provided at both ends of the limiting belt, the rotating columns are rotatably inserted into the rotating holes, and limiting columns are fixed on both sides of the cover plate.

[0009] Preferably, two limiting bars are fixed to the four sides of the packaging box shell respectively, the winding belt is located between the two limiting bars, and a blocking disk is fixed to one end of the rotating column.

[0010] Preferably, a limiting groove is provided on the top surface of the fixing frame, a sealing frame is fixed on the bottom surface of the cover plate, and the sealing frame is interference-fitted with the limiting groove.

[0011] Preferably, two partition plates are fixed to the top surface of the bottom plate, and two sides of the two partition plates that are away from each other are respectively fixed to two sides of the inner portion of the packaging box shell.

[0012] Compared with the prior art, the foam packaging box with an anti-extrusion structure using the above technical solution has the following beneficial effects:

[0013] 1. When the packaging box shell is loaded with items, the items are placed between the primary and secondary binding belts. The primary and secondary binding belts are overlapped, and the hook surface of the Velcro is fitted with the fleece surface. By changing the position of the hook surface on the fleece surface, objects of different sizes can be fixed. When the packaging box shell is subjected to downward extrusion force, the reinforcing bent plate made of corrugated paper is fixed in the installation groove inside the packaging box shell. The reinforcing bent plate is S-shaped and fixed inside the installation groove, which can increase the size of the extrusion force that the packaging box shell can withstand.

[0014] Second, when the user buckles the cover plate onto the top surface of the fixing frame, the limiting belt will be sheathed on the surface of the limiting post, thus fixing the cover plate to the top surface of the fixing frame. At the same time, since the winding belt wraps around the packaging box shell and is located between the two limiting strips, it prevents the winding belt from slipping off the surface of the packaging box shell, thereby increasing the safety of the items stored inside the packaging box shell.

[0015] 3. When the user stores items inside the packaging box shell, the internal space of the packaging box shell will be roughly divided into two spaces by the two partitions, which is convenient for the user to store different items in an orderly manner. When the cover is buckled on the top surface of the fixed frame, the sealing frame made of foam will interference fit into the inside of the limit groove, increasing the sealing between the fixed frame and the cover, and preventing the items stored inside the packaging box shell from being contaminated by dust and other impurities in the external environment.
