Description

Technical Field

[0001] This utility model specifically relates to the field of packaging box technology, and more specifically to a packaging box with cushioning function. Background Technology

[0002] In logistics transportation and cargo storage scenarios, traditional packaging boxes are insufficient in their cushioning and protection capabilities, making it difficult to cope with the impact of complex environments, resulting in a high rate of damage to goods such as precision instruments and fragile items.

[0003] Traditional packaging boxes often use single corrugated cardboard or simple foam filling. The four corners of the box are stress concentration areas, and they are easily damaged by rigid impact when dropped or collided, resulting in the exposure and damage of the internal goods. This problem occurs frequently, especially in the manual loading and unloading scenarios of "last mile" delivery. Simple filling materials such as foam and bubble wrap cannot be adapted to fit and protect goods of different shapes. They are easily lost due to goods shifting or deformation of the cushioning layer. They are even less able to meet the requirements for protecting precision instruments from subtle vibrations. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A packaging box with cushioning function, including

[0007] The packaging box has corner cushioning mechanisms installed at the top and bottom ends and four corners; an internal cushioning mechanism is installed inside the packaging box.

[0008] The internal cushioning mechanism includes a cushioning support frame with a semi-enclosed design. All five sides of the cushioning support frame are connected to the honeycomb EPE pearl cotton layer. The lower end of the cushioning support frame and the upper surface of the honeycomb EPE pearl cotton layer are provided with an air column film layer.

[0009] As a further technical solution of this utility model, the buffer support frame is provided with fixed columns on the left and right sides in a symmetrical manner. The fixed columns are slidably connected to the fixed holes, and the outside of each fixed column is wrapped with a buffer spring.

[0010] As a further technical solution of this utility model, one end of the buffer spring is connected to the outside of the buffer support frame, and the other end is connected to the inside of the outer box; the fixing holes are symmetrically arranged on both sides of the box.

[0011] As a further technical solution of this utility model, an internal buffer mechanism is installed at each of the four corners of the upper and lower ends of the box body; the lower surface of one corner of the lower end of the box body is fixedly connected to the upper end of the buffer support, and the lower surface of the buffer support is symmetrically provided with a buffer spring, the lower end of the buffer spring being fixedly connected to the upper surface of the buffer plate.

[0012] As a further technical solution of this utility model, one end of the buffer plate is provided with a connecting shaft, which is rotatably connected to a rotating hole provided on the inner side of one end of the buffer plate. One side of the buffer plate is fixedly connected to the buffer spring, which is symmetrically arranged on one side of the buffer support.

[0029] 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.

[0030] Please see Figure 1-8 In this embodiment of the present invention, a packaging box with a cushioning function includes a packaging box body 1, and corner cushioning mechanisms 2 are installed at the four corners of the upper and lower ends of the packaging box body 1; an internal cushioning mechanism 3 is installed on the inner side of the packaging box body 1.

[0031] The internal buffer mechanism 3 includes a buffer support frame 31, which is a semi-enclosed design, and all five sides of the buffer support frame 31 are connected to the honeycomb EPE pearl cotton layer 32. The lower end of the buffer support frame 31 and the upper surface of the honeycomb EPE pearl cotton layer 32 are provided with an air column film layer 35.

[0032] The buffer support frame 31 is symmetrically provided with fixed columns 33 on the left and right sides. The fixed columns 33 are slidably connected to the fixed holes 12, and the outside of the fixed columns 33 is wrapped with buffer springs 34.

[0033] One end of the buffer spring 34 is connected to the outside of the buffer support frame 31, and the other end is connected to the inside of the outer box 11; the fixing holes 12 are symmetrically arranged on both sides of the box 11.

[0034] By adopting the above technical solution, the sliding connection between the fixing column 33 and the fixing hole 12 and the setting of the buffer spring 34 enable the internal buffer mechanism 3 to be stably installed in the packaging box 1, maintaining the stability of the structure during the buffering process; the honeycomb EPE pearl cotton layer 32 has good flexibility and elasticity, which can effectively absorb and disperse the impact force; the air column film layer 35 has high elasticity and pressure resistance, which can further enhance the buffering effect.

[0035] In this embodiment, an internal buffer mechanism 3 is installed at each of the four corners of the upper and lower ends of the box 11; the lower surface of one corner of the box 11 is fixedly connected to the upper end of the buffer support 21, and the lower surface of the buffer support 21 is symmetrically provided with buffer springs 22, and the lower end of the buffer springs 22 is fixedly connected to the upper surface of the buffer plate 23.

[0036] One end of the buffer plate 23 is provided with a connecting shaft 24, which is rotatably connected to a rotating hole provided on the inner side of one end of the buffer plate 25. One side of the buffer plate 25 is fixedly connected to the buffer spring 26. The buffer spring 26 is symmetrically arranged on one side of the buffer support 27. The other side of the buffer support 27 is fixedly connected to one side of the lower corner of the outer casing 11.

[0037] By adopting the above technical solution, the first buffer plate 23 and the second buffer plate 25 in the corner buffer mechanism 2 at the four corners of the upper and lower ends of the packaging box 1 are connected by the rotating shaft 24 and, together with the second buffer spring 26, can flexibly adjust the buffer angle when subjected to impact forces from different directions, ensuring the buffering effect while guaranteeing the reliability of the structure.

[0038] Buffer spring 1 22, buffer spring 26 and buffer spring 3 34 can convert impact force into elastic potential energy. Through the compression and extension process of the spring, the impact force is effectively buffered and absorbed. Compared with traditional packaging boxes, the buffering performance of this packaging box is significantly improved.

[0039] The working principle of this utility model is as follows: When the packaging box 1 is subjected to an external impact force, the corner buffer mechanism 2 installed at the four corners of the upper and lower ends of the packaging box 1 provides initial buffering. Taking the corner where the buffer support 21 is located as an example, the impact force acts on the buffer support 21, causing the buffer spring 22 to compress and convert the impact force into the elastic potential energy of the spring. The buffer plate 23 moves downward under the action of the spring, achieving an initial buffering effect. At the same time, the buffer plate 23 is rotated to the buffer plate 25 through the connecting shaft 24, dispersing part of the impact force to the buffer spring 26. The buffer spring 26 is compressed to further absorb the impact force, thereby effectively buffering the impact force from the corner.

[0040] The internal buffer mechanism 3 is responsible for dealing with the displacement and collision of items inside the packaging box caused by vibration and impact. When the items inside the box move due to external force, the semi-enclosed buffer support frame 31 and the honeycomb EPE pearl cotton layer 32 connected to the five sides first play a flexible buffering role. At the same time, the fixing column 33 slides in the fixing hole 12, and the buffer spring 34 undergoes elastic deformation when compressed, converting the impact force of the items into the elastic potential energy of the spring, thereby limiting the excessive movement of the items and preventing the items from violently colliding with the inner wall of the packaging box. The air column film layer 35 on the upper surface of the honeycomb EPE pearl cotton layer 32 at the lower end can further absorb the impact force from below, providing more comprehensive buffer protection for the items inside the box.

[0041] The sliding connection between the fixing post 33 and the fixing hole 12, as well as the setting of the buffer spring 34, enable the internal buffer mechanism 3 to be stably installed inside the packaging box 1, maintaining the stability of the structure during the buffering process; the honeycomb EPE pearl cotton layer 32 has good flexibility and elasticity, which can effectively absorb and disperse the impact force; the air column film layer 35 has high elasticity and pressure resistance, which can further enhance the buffering effect.

[0042] The corner buffer mechanism 2 at the four corners of the upper and lower ends of the packaging box 1 has a buffer plate 23 and a buffer plate 25 connected by a rotating shaft 24. Together with a buffer spring 26, it can flexibly adjust the buffer angle when subjected to impact forces from different directions, ensuring the buffering effect while guaranteeing the reliability of the structure.

[0043] Buffer spring 1 22, buffer spring 26 and buffer spring 3 34 can convert impact force into elastic potential energy. Through the compression and extension process of the spring, the impact force is effectively buffered and absorbed. Compared with traditional packaging boxes, the buffering performance of this packaging box is significantly improved.
