Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to an integrated buffer packaging box. Background Art

[0002] A packaging box is a rigid or semi-rigid container with a regular geometric shape. It can be classified by material or by product name to prevent the product from being damaged or contaminated during transportation, storage and sales. An integrated packaging box is a packaging box that integrates the box body and lining.

[0003] When using a packaging box, the items to be stored need to be placed inside the box. However, the packaging boxes on the market usually have a simple structure and do not have a cushioning effect. When transporting valuable items in a packaging box, fillers are usually inserted into the box to increase the protective effect of the packaging box. However, when heavy and expensive items are placed in the packaging box, a large impact force will be generated between the bottom of the item and the bottom surface of the box, which can easily cause damage to the item. Therefore, in response to the above problem, we propose a new type of integrated cushioning packaging box. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that the packaging box has a single structure and does not have a cushioning effect, and the impact force generated when heavy and expensive items are put in the box easily causes damage to the items, and proposes an integrated cushioning packaging box.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an integrated buffer packaging box, including a packaging box body, the inner bottom of the packaging box body is fixedly connected to a circular shell near the four corners, the top of the circular shell is provided with a slide groove, the inner wall of the circular shell is provided with a piston, the top of the piston is fixedly connected to a pull rod, the outer surface of the pull rod is slidably fitted with the inner wall of the slide groove, and a connecting tube is fixedly connected between the outer surfaces of adjacent circular shells near the bottom.

[0006] Preferably, the outer surface of one of the connecting pipes is fixedly connected to an air inlet pipe, the outer surface of the air inlet pipe slides through the inner wall of the packaging box body and extends to the outside, and a one-way valve is installed between the inner walls of the air inlet pipe.

[0007] Preferably, a pressure gauge is provided on the outer surface of the air intake pipe, and a sealing cover is threadedly connected to the left end of the air intake pipe.

[0008] Preferably, a partition is fixedly connected between the tops of the plurality of pull rods, and an anti-skid plate is fixedly connected to the top of the partition.

[0009] Preferably, a spring is provided between the bottom of the partition and the inner bottom of the packaging box body.

[0010] Preferably, a top cover is provided on the top of the packaging box body.

[0011] Preferably, a clamping block is installed on the outer surface of the pull rod, and the clamping block is located between the inner top of the circular shell and the top of the piston.

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

[0013] 1. In the utility model, when in use, an article is placed on the anti-slip plate inside the packaging box body. Affected by the weight of the article, the partition below the anti-slip plate will move downward and drive the piston to move downward synchronously inside the circular shell through the pull rod, and the extrusion spring will contract. During the downward movement of the piston, the nitrogen inside the circular shell will be affected by the piston and compressed, and during the process, affected by the friction between the piston surface and the inner wall of the circular shell, the piston will move up and down slowly, and generate an upward extrusion force through the rebound of the spring. Therefore, the impact force generated by placing heavy and expensive articles on the top of the anti-slip plate inside the packaging box body will be effectively buffered, thereby avoiding damage to the articles and improving the use effect of the packaging box.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments 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 of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides an integrated buffer packaging box, including a packaging box body 1, wherein the inner bottom of the packaging box body 1 is fixedly connected to a circular shell 3 near the four corners, the top of the circular shell 3 is provided with a slide groove 34, the inner surface wall of the circular shell 3 is provided with a piston 32, the top of the piston 32 is fixedly connected to a pull rod 33, the outer surface of the pull rod 33 is slidably fitted with the inner surface wall of the slide groove 34, and the outer surfaces of adjacent circular shells 3 are fixedly connected to a connecting pipe 4 near the bottom, and the outer surface of one of the connecting pipes 4 is fixedly connected to An air inlet pipe 41 is provided, and the outer surface of the air inlet pipe 41 slides through the inner wall of the packaging box body 1 and extends to the outside, a one-way valve 43 is installed between the inner walls of the air inlet pipe 41, and a pressure gauge 44 is provided on the outer surface of the air inlet pipe 41. A sealing cover 42 is threadedly connected to the left end of the air inlet pipe 41, a partition 2 is fixedly connected between the tops of multiple pull rods 33, an anti-skid plate 21 is fixedly connected to the top of the partition 2, a spring 5 is provided between the bottom of the partition 2 and the inner bottom of the packaging box body 1, and a top cover 11 is provided on the top of the packaging box body 1.

[0024] The effect achieved by the entire embodiment 1 is that, when in use, by placing an article on the anti-slip plate 21 inside the packaging box body 1, under the influence of the weight of the article, the partition 2 below the anti-slip plate 21 will move downward and drive the piston 32 to move downward synchronously inside the circular shell 3 through the pull rod 33, and the extrusion spring 5 will contract. During the downward movement of the piston 32, the nitrogen inside the circular shell 3 will be affected by the piston 32 and compressed. Nitrogen is an inert gas with a stable molecular structure and will not undergo chemical changes when compressed. Therefore, the nitrogen inside the circular shell 3 will return to its original state after being compressed, thereby playing a buffering role. In the process, the piston 32 will be affected by the friction between the surface of the piston 32 and the inner wall of the circular shell 3, and the piston 32 will move slowly when it moves up and down. , and an upward squeezing force is generated by the rebound of the spring 5. Therefore, the impact force generated when heavy and expensive items are placed on the top of the anti-slide plate 21 inside the packaging box body 1 will be effectively buffered, thereby avoiding damage to the items and improving the use effect of the packaging box. The design of the anti-slide plate 21 can prevent the items from sliding freely inside the packaging box body 1 to a certain extent. Under the action of the barometer 44, it is possible to judge whether the nitrogen inside the circular shell 3 is sufficient. When the nitrogen is insufficient, the sealing cover 42 is opened, and the nitrogen can be supplemented to the inside of the circular shell 3 through the cooperation of the air intake pipe 41 and the connecting pipe 4. The operation is simple, and the one-way valve 43 installed inside the air intake pipe 41 only allows the gas inside the air intake pipe 41 to flow in one direction.

[0025] Embodiment 2, as Figure 1-Figure 5 As shown, a clamping block 31 is installed on the outer surface of the pull rod 33 , and the clamping block 31 is located between the inner top of the circular shell 3 and the top of the piston 32 .

[0026] The effect achieved by the entire embodiment 2 is that the block 31 serves to isolate the piston 32 from the inner top of the circular shell 3, thereby preventing the piston 32 from continuously moving up and down and hitting the inner top of the circular shell 3, thereby preventing the piston 32 from being damaged.

[0027] Working principle: When in use, by placing the items on the anti-slip plate 21 inside the packaging box body 1, under the influence of the weight of the items, the partition 2 under the anti-slip plate 21 will move downward and drive the piston 32 to move downward synchronously inside the circular shell 3 through the pull rod 33, and the extrusion spring 5 will shrink. During the downward movement of the piston 32, the nitrogen inside the circular shell 3 will be affected by the piston 32 and compressed, and during the process, under the influence of the friction between the surface of the piston 32 and the inner wall of the circular shell 3, the piston 32 will move up and down slowly, and generate an upward extrusion force through the rebound of the spring 5. Therefore, the impact force generated by placing heavy and expensive items on the top of the anti-slip plate 21 inside the packaging box body 1 will be effectively buffered, thereby avoiding damage to the items and improving the use effect of the packaging box. In addition, the block 31 plays a role in isolating the piston 32 from the inner top of the circular shell 3, preventing the piston 32 from continuously moving up and down and hitting the inner top of the circular shell 3, causing damage to the piston 32.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. 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 and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
