[0001] The utility model relates to the technical field of packaging boxes, in particular to a pressure-resistant packaging box. Background Art

[0002] The design and application of packaging boxes has become an indispensable part of modern logistics and transportation. Packaging boxes are not only an important means of protecting products, but also a fundamental unit that plays a key role in supply chain management. Their main functions include protecting goods, facilitating handling and storage, conveying information, and enhancing product image.

[0003] In the prior art, when using packaging boxes to package and transport items, since traditional packaging boxes have a single structure and lack a good pressure-resistant structure, when the packaging boxes are stacked and transported, the bottom packaging boxes will be damaged due to excessive pressure on the bottom packaging boxes and bumpy roads, causing damage to the items inside and increasing costs. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that when the above equipment is in use, the packaging box cannot withstand a large pressure, resulting in damage to the packaging box when the packaging box is stacked for transportation, thereby proposing a pressure-resistant packaging box.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a pressure-resistant packaging box, comprising a bottom plate, four support columns are fixedly installed on the top of the bottom plate, a mounting plate is fixedly installed between the outer walls of two of the four support columns, two movable grooves are provided on the tops of the two mounting plates, movable blocks are movably embedded in the inner walls of the four movable grooves, buffer springs are provided on the inner walls of the four movable grooves, and one side of the outer wall of the buffer spring is fixedly connected to one side of the outer wall of the movable block, dampers are provided on the inner walls of the four buffer springs, connecting rods are movably sleeved on the outer walls of the four connecting rods, fixed blocks are movably inserted on the inner walls of the four connecting rods, a fixing plate is fixedly installed between the tops of every two of the four fixed blocks, and a top plate is fixedly installed between the tops of the two fixed plates by bolts.

[0006] Preferably, four limiting columns are fixedly installed on the bottom of the top plate, and the outer walls of the four limiting columns are all provided with guide grooves.

[0007] Preferably, the outer walls of the four limiting columns are movably inserted into the interior of the supporting column, and a mounting box is fixedly mounted on one side of the outer walls of the four supporting columns.

[0008] Preferably, the inner walls of the four installation boxes are all provided with limiting springs.

[0009] Preferably, a limiting rod is movably embedded in the inner surface wall of each of the four installation boxes, and one side of the outer wall of the limiting rod is fixedly connected to one side of the outer wall of the limiting spring.

[0010] Preferably, the outer walls of the four limiting rods are movably inserted into the guide groove, and a support frame is fixedly installed between the outer walls of two of the four support columns.

[0011] Preferably, a box body is provided on the top of the base plate, and four supporting legs are fixedly installed on the bottom of the base plate.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] During use, the utility model can support the top plate after the packing boxes are stacked up by means of the action of the buffer springs, dampers, movable blocks, limit rods and other structures, so as to avoid the pressure generated by the upper packing boxes directly acting on the lower packing boxes, thereby protecting the lower packing boxes. When bumps occur during transportation, the upper packing boxes will vibrate and act on the top plate. At this time, the vibrations generated by the upper packing boxes can be buffered and absorbed by means of the cooperation of the buffer springs, dampers, movable blocks, link rods and other structures, so as to avoid the impact force acting on the lower packing boxes, thereby protecting the packing boxes and the items inside the packing boxes, and avoiding the damage to the lower packing boxes and the items inside the packing boxes caused by excessive pressure from the upper packing boxes, thereby greatly reducing cost consumption.

[0014] When the utility model is in use, when it is necessary to place an article into the packaging box, the staff can press the limit rod to remove it from the guide groove, thereby disassembling the top plate, making it more convenient to place the article into the packaging box. After the article is packed, the top cover is limited by the limit rod, limit spring and other structures, and the packaging box is protected with the cooperation of other structures. Under the action of the support frame, the strength of the support column can be increased to improve the protection effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: Figure 1-Figure 4 As shown, the utility model provides a pressure-resistant packaging box, including a bottom plate 1, four support columns 3 are fixedly installed on the top of the bottom plate 1, and a mounting plate 4 is fixedly installed between the outer walls of two of the four support columns 3, and two movable grooves 5 are provided on the tops of the two mounting plates 4, and movable blocks 6 are movably embedded in the inner walls of the four movable grooves 5, and buffer springs 7 are provided on the inner walls of the four movable grooves 5, and one side of the outer wall of the buffer spring 7 is fixedly connected to one side of the outer wall of the movable block 6, and dampers 8 are provided on the inner walls of the four buffer springs 7, and connecting rods 9 are movably sleeved on the outer walls of the four connecting rods 9, and fixed blocks 10 are movably inserted into the inner walls of the four fixing blocks 10, and a fixing plate 11 is fixedly installed between the tops of every two of the four fixing blocks 10, and a top plate 12 is fixedly installed between the tops of the two fixing plates 11 by bolts.

[0024] The effect achieved by the entire embodiment 1 is that when the items are packaged and the packaging boxes are stacked for transportation, the top plate 12 can be supported by the action of the buffer spring 7, damper 8, movable block 6, connecting rod 9, fixed block 10, and fixed plate 11, so as to prevent the pressure generated by the packaging box above the top plate 12 from directly acting on the packaging box, thereby protecting the packaging box below. In addition, during transportation, when the road is bumpy, the packaging box above the top plate 12 will vibrate, and the force generated by the vibration will act on the top plate 12. At the same time, under the action of the fixed plate 11, fixed block 10 and connecting rod 9, the movable block 6 will be driven to move inside the movable groove 5 and compress the buffer spring 7. When the buffer spring 7 is compressed to a certain extent, a large rebound force will be generated. At this time, the rebound force generated by the buffer spring 7 can be partially absorbed by the action of the damper 8, thereby buffering the vibration generated by the packaging box above, further protecting the packaging box and the items inside the packaging box, and improving the practicality of the packaging box.

[0025] Example 2: Figure 2-Figure 4 As shown, four limit columns 13 are fixedly installed at the bottom of the top plate 12, and the outer walls of the four limit columns 13 are provided with guide grooves 14. The outer walls of the four limit columns 13 are movably inserted into the interior of the support columns 3, and one side of the outer wall of the four support columns 3 is fixedly installed with a mounting box 15. The inner wall of the four mounting boxes 15 is provided with a limit spring 16, and the inner wall of the four mounting boxes 15 is movably embedded with a limit rod 17, and one side of the outer wall of the limit rod 17 is fixedly connected to one side of the outer wall of the limit spring 16, and the outer walls of the four limit rods 17 are movably inserted into the interior of the guide groove 14, and a support frame 18 is fixedly installed between the outer walls of two of the four support columns 3, a box 19 is provided on the top of the bottom plate 1, and four supporting feet 2 are fixedly installed on the bottom of the bottom plate 1.

[0026] The effect achieved by the entire embodiment 2 is that when it is necessary to place an item into the packaging box, the staff can manually press the limit rod 17 to make it move inside the installation box 15 and compress the limit spring 16, so that the limit rod 17 no longer limits the limit column 13, and then the limit column 13 is taken out from the support column 3, thereby completing the disassembly of the top plate 12 and placing the item into the box body 19. When the item is placed, the limit column 13 is inserted into the support column 3, and the limit rod 17 is released. Under the action of the limit spring 16, the limit rod 17 is inserted into the guide groove 14, thereby limiting the limit column 13 and preventing it from falling off during use. In addition, during use, under the action of the support column 3, the limit column 13, the guide groove 14, and the limit rod 17, the top plate 12 can be limited, thereby improving the protection effect of the packaging box. At the same time, under the action of the support frame 18, the strength between the support columns 3 can be improved to avoid damage during use.

[0027] Working principle: When it is necessary to place items inside the packaging box for transportation, first, under manual operation of the staff, press the limit rod 17 to make it move inside the installation box 15 and compress the limit spring 16, so that the limit rod 17 no longer limits the limit column 13, and then remove the limit column 13 from the inside of the support column 3, and at the same time rotate the bolts installed on the outer wall of the fixing plate 11 to complete the disassembly of the top plate 12 and place the items inside the packaging box, and then complete the installation of the top plate 12 by the above method. When the items are packed and the packaging box is stacked for transportation, the top plate 12 can be supported by the buffer spring 7, damper 8, movable block 6, connecting rod 9, fixed block 10, and fixed plate 11 to avoid direct action of the pressure generated by the packaging box above the top plate 12. To the packaging box, thereby protecting the packaging box below, and in the process of transportation, when the road is bumpy, the packaging box above the top plate 12 will vibrate, and the force generated by the vibration will act on the top plate 12. At the same time, under the action of the fixed plate 11, the fixed block 10 and the connecting rod 9, the movable block 6 will be driven to move inside the movable groove 5 and compress the buffer spring 7. When the buffer spring 7 is compressed to a certain extent, a large rebound force will be generated. At this time, under the action of the damper 8, the rebound force generated by the buffer spring 7 can be partially absorbed, thereby buffering the vibration generated by the upper packaging box, avoiding the lower packaging box from being damaged by large pressure, and then improving the pressure resistance of the packaging box to protect the packaging box and the items inside the packaging box.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
