The box body has a support block inside, and the bottom of the support block has a pressing mechanism. The pressing mechanism includes a bottom plate that abuts against the bottom surface of the box body. The upper surface of the bottom plate has a gear and a limiting member. A first rack is meshed on one side of the gear, and a pressing block is provided at the end of the first rack away from the gear. In this way, the present invention improves the anti-deformation ability of the side of the box body. At the same time, the pressing mechanism does not affect the use of the box body, nor does it cause insufficient space when multiple cardboard boxes are stacked.

[0004] Based on the search of the aforementioned patents and in conjunction with existing corrugated cardboard boxes, it was found that although the aforementioned corrugated cardboard boxes can support the sides of the boxes by moving the extrusion blocks through a transmission structure of multiple gears and racks, their structure is relatively complex, the production and maintenance costs are relatively high, and the weight of the support structure is relatively heavy, making it difficult to handle the corrugated cardboard boxes and thus resulting in insufficient practicality. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a compression-resistant corrugated cardboard box. This solves the problem mentioned in the background art that, although the existing corrugated cardboard boxes can support the sides of the box by moving the compression block through a transmission structure of multiple gears and racks, their structure is relatively complex, the production and maintenance costs are relatively high, and the support structure is relatively heavy, making it difficult to handle the corrugated cardboard box and thus resulting in insufficient practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a compression-resistant corrugated cardboard box, comprising a box body, a support component for protecting the box body, and a stacking component for improving placement stability. The support component includes a fixed frame disposed within the box body, a plurality of sliding grooves evenly arranged around the fixed frame, a sliding rod disposed within the sliding groove, a support plate fixedly connected to one end of the sliding rod, and a first spring sleeved on the outside of the sliding rod. The sliding rod extends into the sliding groove and is slidably connected to the sliding groove. The support plate contacts the inner wall of the box body, and the two ends of the first spring are fixedly connected to the support plate and the fixed frame, respectively.

[0007] Preferably, the stacking component includes a fixing block fixedly connected to the top four sides of the box body, a slot opened on the top of the fixing block, an insert block fixedly connected to the bottom four sides of the box body, a limiting groove opened on both sides of the slot, a limiting plate fixedly connected to both sides of the insert block, and a buffer component for buffering the box body. The insert block is slidably connected to the slot, and the limiting plate is slidably connected to the limiting groove.

[0008] Preferably, the box body has multiple support frames evenly arranged at its four corners, and the support frames are L-shaped.

[0009] Preferably, the buffer component includes a groove formed at the bottom of the insert block, a guide rod connected to the groove, a buffer plate fixedly connected to the bottom of the guide rod, and a second spring fixedly connected to the top of the guide rod, wherein the guide rod is slidably connected to the groove.

[0010] Preferably, a limiting groove is provided on one side of the slide rod, and a limiting block is fixedly connected to the inner wall of the slide groove, and the limiting block is slidably connected to the limiting groove.

[0011] Preferably, the inner wall of the support frame is provided with a reinforcing plate, and the reinforcing plate is fixedly connected to the support frame.

[0012] Preferably, the groove is T-shaped and the guide rod is T-shaped.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By setting up the box body and supporting components, the fixed frame can be placed inside the box body, and the support plate contacts the inner wall of the box body to support it. Utilizing the elasticity of the first spring, the box body's resistance to compression can be improved. The support frame and reinforcing plate can support the box body from the four corners, which can further improve the resistance to compression. The box body can be supported using a relatively simple structure, which can reduce the cost of use and greatly reduce the weight, making it easy to handle and stack, thereby improving its practicality.

[0015] 2. By incorporating stacking components, insert blocks can be inserted into slots when stacking boxes. Limiting plates enhance the stability of the insert blocks and improve the stability of stacking boxes, preventing upper boxes from slipping off lower boxes. Simultaneously, the elasticity of the second spring acts as a buffer when stacking boxes, preventing direct impact damage and further enhancing practicality. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4This utility model provides a technical solution: a compression-resistant corrugated cardboard box, including a box body 1, a support component for protecting the box body 1, and a stacking component for improving stacking stability. The support component includes a fixed frame 21 disposed inside the box body 1, a plurality of sliding grooves 22 evenly arranged around the fixed frame 21, a sliding rod 23 disposed in the sliding grooves 22, a support plate 24 fixedly connected to one end of the sliding rod 23, and a first spring 25 sleeved on the outside of the sliding rod 23. The sliding rod 23 extends into the sliding groove 22 and is slidably connected to the sliding groove 22. The support plate 24 contacts the inner wall of the box body 1. The two ends of the first spring 25 are fixedly connected to the support plate 24 and the fixed frame 21, respectively. The support plate 24 can contact the inner wall of the box body 1, which can support the inner wall of the box body 1 and prevent the box body 1 from being crushed and damaged. The spring 25 utilizes its elasticity... The inner corners of the box 1 are provided with multiple evenly arranged support frames 41. The support frames 41 are L-shaped and can support the inner corners of the box 1, thereby further improving the anti-compression stability and increasing the strength of the box 1. A limiting groove 61 is provided on one side of the slide rod 23. A limiting block 62 is fixedly connected to the inner wall of the slide groove 22. The limiting block 62 is slidably connected to the limiting groove 61. The limiting block 62 can limit the slide rod 23, prevent the first spring 25 from being over-deformed, and improve the stability of the first spring 25. A reinforcing plate 411 is provided on the inner wall of the support frame 41. The reinforcing plate 411 is fixedly connected to the support frame 41. The reinforcing plate 411 can increase the strength of the support frame 41, thereby further improving the strength of the box 1.

[0025] Please see Figure 1 , Figure 2 , Figure 5 as well as Figure 6The stacking components include fixing blocks 31 fixedly connected to the top four sides of the box 1, slots 32 formed on the top of the fixing blocks 31, insert blocks 33 fixedly connected to the bottom four sides of the box 1, limiting grooves 34 formed on both sides of the slots 32, limiting plates 35 fixedly connected to both sides of the insert blocks 33, and buffer components for cushioning the box 1. The insert blocks 33 are slidably connected to the slots 32, and the limiting plates 35 are slidably connected to the limiting grooves 34. When the boxes 1 are stacked, the insert blocks 33 can be inserted into the slots 32, and the limiting plates 35 can be inserted into the limiting grooves 34. This allows multiple boxes 1 to be stacked, while also improving the stability of the stacking and preventing the upper boxes 1 from falling off the lower ones. The cushioning component, which is slidable on the box 1, includes a groove 51 at the bottom of the insert block 33, a guide rod 52 connected to the groove 51, a buffer plate 53 fixedly connected to the bottom of the guide rod 52, and a second spring 54 fixedly connected to the top of the guide rod 52. The guide rod 52 is slidably connected to the groove 51, and the buffer plate 53 can contact the bottom of the slot 32, thereby driving the guide rod 52 to move and causing the second spring 54 to deform. The elasticity of the second spring 54 can play a cushioning role and prevent the boxes 1 from being damaged by impact when they are stacked. The groove 51 is T-shaped and the guide rod 52 is T-shaped, which can limit the movement distance of the guide rod 52 and prevent the guide rod 52 from falling out of the groove 51.

[0026] Working principle: During operation, the fixed frame 21 is placed into the box 1, pushing the support plate 24 to move. The movement of the support plate 24 drives the slide rod 23 to move, and at the same time, the first spring 25 is compressed and deformed. The force generated by the deformation of the first spring 25 can push the support plate 24 to contact the inner wall of the box 1. The support plate 24 and the first spring 25 can support the box 1, which can improve the strength of the box 1 and improve its resistance to deformation. The reinforcing plate 411 and the support frame 41 can support the four inner corners of the box 1, which can further improve the strength of the box 1 and further improve its resistance to deformation. When it is necessary to stack the boxes... When one box 1 is in use, the insert block 33 and the limiting plate 35 at the bottom of the box 1 are aligned with the slot 32 and the limiting groove 34 at the top of the other box 1, and inserted into the slot 32 and the limiting groove 34. The buffer plate 53 contacts the bottom of the slot 32. The buffer plate 53 moves upward, pushing the guide rod 52 to move. The movement of the guide rod 52 causes the second spring 54 to deform. The second spring 54 can be used for buffering, which can prevent the box 1 from being damaged when stacked. Moreover, after the insert block 33 is inserted into the slot 32, it can prevent the box 1 from shifting and slipping. The above is the working process of the whole device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0027] 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.
