A crush resistant packaging box

Abstract

This utility model discloses a crush-resistant packaging box, including a box body, a box lid fixedly installed on the top of the box body, a reinforcing plate overlapping inside the box body, a protective pad overlapping on the lower side wall of the box body, and a crush-resistant assembly inside the box body. When the box body is squeezed, the box body will exert pressure on the crush-resistant assembly, and the crush-resistant assembly will buffer and resist the squeezing force of the box body through its own elasticity, thereby increasing the pressure resistance of the box body. Moreover, through the reinforcing plate, the crush-resistant assembly, together with the reinforcing plate, supports the corners of the box body, which can increase the strength of the corners of the box body, making the corners of the box body less prone to deformation. This avoids the packaging box from deforming and being damaged when squeezed, thus preventing the contents inside from being squeezed, and thus better protecting the contents.

Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a compression-resistant packaging box. Background Technology

[0002] Packaging boxes, as the name suggests, are boxes used to package products. They can be classified by material, such as: paper boxes, iron boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, and corrugated packaging boxes. Merchants generally use packaging boxes to package some items, with foam or paper wrapped around the items for protection. The structure is relatively simple, but these types of packaging boxes are generally made of cardboard, especially in the express delivery industry.

[0003] However, cardboard packaging boxes are not very resistant to pressure and most of them do not have additional supporting structures inside. This makes the packaging boxes easy to deform and be damaged when squeezed, which in turn causes the contents inside to be squeezed and makes it difficult to provide good protection for the contents. Based on the above problems, this application proposes a compression-resistant packaging box. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a crush-resistant packaging box to solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A crush-resistant packaging box includes a box body, a box lid fixedly installed on the top of the box body, a reinforcing plate overlapping inside the box body, a protective pad overlapping on the lower side wall of the box body, and a crush-resistant component installed inside the box body.

[0006] Preferably, the anti-pinch component includes a connecting column overlapping inside the housing, with connecting grooves at both ends of the connecting column, a mounting column slidably disposed inside the connecting groove, mounting holes at both ends of the mounting column, elastic blocks overlapping at both ends of the mounting column, connecting holes on the surface of the elastic blocks, fixing bolts overlapping inside the connecting holes, the fixing bolts being threadedly connected to the mounting holes, and a connecting plate being fixedly disposed on the surface of the mounting column.

[0007] Preferably, the connecting posts have an L-shaped structure, and there are eight connecting posts, which are symmetrically distributed.

[0008] Preferably, the connecting hole mainly consists of a mounting hole and a limiting hole, wherein the radius of the mounting hole is larger than the radius of the limiting hole.

[0009] Preferably, the elastic block has a rectangular structure, the elastic block is an elastic rubber block, and the elastic block and the connecting groove are slidably connected.

[0010] Preferably, the protective pad has a rectangular structure and is made of sponge.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When the box body is squeezed, the box body will exert pressure on the anti-squeeze component. The anti-squeeze component, through its own elasticity, buffers and resists the squeezing force of the box body, thereby increasing the box body's pressure resistance. Moreover, through the reinforcing plate, the anti-squeeze component, together with the reinforcing plate, supports the corners of the box body, which can increase the strength of the corners of the box body, making the corners of the box body less prone to deformation. This avoids the packaging box from deforming and being damaged when squeezed, causing the contents inside to be squeezed, thus providing better protection for the contents.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Refer to Figure 1-4A compression-resistant packaging box includes a box body 1, a box cover 2 fixedly mounted on the top of the box body 1, a reinforcing plate 3 overlapping inside the box body 1, a protective pad 12 overlapping on the lower side wall of the box body 1, and a compression-resistant component inside the box body 1. The compression-resistant component includes a connecting post 4 overlapping inside the box body 1, connecting grooves 5 at both ends of the connecting post 4, a mounting post 6 slidably mounted inside the connecting grooves 5, mounting holes 7 at both ends of the mounting post 6, and elastic blocks 8 overlapping at both ends of the mounting post 6. The elastic blocks 8 are rectangular in structure and are elastic rubber blocks. The elastic blocks 8 are slidably connected to the connecting grooves 5. Connecting holes 9 are provided on the surface of the elastic blocks 8, and fixing bolts 10 are overlapping inside the connecting holes 9. The fixing bolts 10 are threadedly connected to the mounting holes 7. A connecting plate 11 is fixedly mounted on the surface of the mounting post 6. When the box body 1 is compressed, the mounting post 6 is pushed by the connecting plate 11 on the compressed surface of the box body 1, causing the mounting post 6 to move the connecting post 4 on the compressed surface, thus compressing the box body 1. The connecting post 4 compresses the elastic block 8 on the uncompressed surface by driving the inner wall of the connecting groove 5, causing the connecting post 4 and the mounting post 6 to move relative to each other. The rebound effect of the mounting post 6 cancels out the compressive force, thus compressing the box 1. The items placed inside the box 1 will not be compressed. When the anti-compression component is not in use, it can be removed from the box 1 for reuse. When the elastic block 8 is damaged, after removing the anti-compression component from the box 1, the connecting post 4 is pulled to move it, separating the connecting post 4 and the mounting post 6, allowing the elastic block 8 to move out of the connecting groove 5. The fixing bolt 10 is then removed, and the elastic block 8 can be taken out. The replacement elastic block 8 is placed at the end of the mounting post 6, and the fixing bolt 10 is inserted into the connecting hole 9. The connecting hole 9 is then rotated to tighten it inside the mounting hole 7, thus fixing the elastic block 8. The elastic block 8 is then reinserted into the connecting groove 5 through the mounting post 6, allowing the anti-compression component to be used normally.

[0016] Specifically, the connecting column 4 has an L-shaped structure, and there are eight connecting columns 4 in total. The eight connecting columns 4 are symmetrically distributed. The L-shaped connecting column 4 can work with the reinforcing plate 3 to support the corner of the box 1, so that the corner of the box 1 can withstand greater pressure, thereby avoiding deformation and damage at the corner of the box 1.

[0017] Specifically, the connecting hole 9 mainly consists of a mounting hole and a limiting hole. The radius of the mounting hole is larger than that of the limiting hole. The mounting hole facilitates the insertion of the top cap of the fixing bolt 10 into the connecting hole 9, while the limiting hole allows the screw of the fixing bolt 10 to pass through and limits the top cap of the fixing bolt 10, thereby facilitating the installation of the elastic block 8 on the mounting post 6.

[0018] Specifically, the protective pad 12 has a rectangular structure and is made of sponge. The sponge-made protective pad 12 can be placed on the bottom of the item to protect it and prevent the bottom of the item from being damaged by vibration.

[0019] In use: When the box 1 is squeezed, the box 1 will be pushed by the connecting plate 11 on the squeezed surface to move the mounting column 6, which in turn drives the connecting column 4 on the squeezed surface to move. This causes the connecting column 4 to drive the inner wall of the connecting groove 5 to compress the elastic block 8 on the unsqueezed surface, causing the connecting column 4 and the mounting column 6 to move relative to each other. The rebound effect of the mounting column 6 cancels out the squeezing force, thus squeezing the box 1, but preventing the items placed inside the box 1 from being squeezed.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
