The buffer mechanism includes a support base, a buffer pad, and a contact plate. The bottom of the box body has a support base, and the inner end of the support base has at least two sets of buffer pads at equal intervals. The top of each buffer pad is connected to the bottom surface of a contact plate.

[0007] Preferably, the components of the two sets of cover plates are the same. Each cover plate has an inner plate at its inner end and a connecting cylinder at its bottom surface. The bottom end of the connecting cylinder is connected to a pressure plate, and the inner end of the connecting cylinder is provided with a buffer block. The inner end of the buffer block is provided with no less than two cavities. Each cavity is provided with a spring, and the upper and lower ends of the spring are respectively connected to the bottom surface of the cover plate and the top surface of the pressure plate.

[0008] Preferably, the buffer block has a gap.

[0009] Preferably, the outer side of the connecting cylinder is provided with corrugated pleats.

[0010] Preferably, the friction plate is arc-shaped and has a cover at its top.

[0011] Preferably, the outer edge of the contact plate is provided with a groove corresponding to the friction plate.

[0012] Preferably, the support base is grid-shaped, and the buffer pad is disposed in the grid.

[0013] Preferably, the top of the cushioning pad can extend to the top of the support base.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The box is equipped with a cover plate connected to both the left and right ends of the top surface. The inner side of the box is equipped with a friction plate, and the bottom end is connected to a buffer mechanism. The buffer mechanism includes a support base, a buffer pad, and a contact plate. The buffer pad and the support base work together to support and buffer the contact plate, thus providing cushioning protection for items placed on top of the contact plate. This prevents damage to goods due to vibration or other factors during transportation and handling, effectively improving the protection of items. It is adaptable to different usage environments, meets people's usage needs, and has strong practicality. Attached Figure Description

[0022] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0023] Please see Figure 1-4 This utility model provides a corrugated cardboard box with a built-in buffer structure, including a box body 1. A set of cover plates 2 are provided on the left and right ends of the top surface of the box body 1. After the two sets of cover plates 2 are flipped, they can cover the top opening of the box body 1. At least two sets of friction plates 11 are provided at equal intervals on the four ends inside the box body 1. The friction plates 11 are arc-shaped and fit against the inner side of the box body 1. They can clamp and limit the items placed in the box body 1. The top of the friction plate 11 is provided with an arc-shaped cover, which is conducive to the placement of items.

[0024] A set of buffer mechanisms 12 is provided at the bottom of the inner box 1. The buffer mechanism 12 includes a support base 121, a buffer pad 122, and a contact plate 123. The support base 121 is grid-shaped. At least two sets of buffer pads 122 are evenly spaced at the inner end of the support base 121. The buffer pads 122 are located in the grid. The top of each buffer pad 122 is connected to the bottom surface of a set of contact plates 123. The outer edge of the contact plate 123 is provided with a groove corresponding to the friction plate 11 to facilitate the up and down movement of the contact plate 123. The top of the buffer pad 122 can extend to the top of the support base 121. The buffer pad 122 is made of rubber and can shock absorb and buffer items on the contact plate 123 to improve the protection effect.

[0025] Please see Figure 2-5 This utility model provides a corrugated cardboard box with a built-in cushioning structure. The components of the two sets of cover plates 2 are the same. Each cover plate 2 has an inner plate 21 at its inner end, which can improve the strength of the cover plate 2. The bottom surface of the cover plate 2 has a set of connecting cylinders 22. The outer side of the connecting cylinders 22 has corrugated pleats, which can be folded. The bottom end of the connecting cylinders 22 is connected to a set of pressure plates 23, and the inner end of the connecting cylinders 22 has a buffer block 24. The buffer block 24 has a gap and is made of sponge, which can be squeezed. The inner end of the buffer block 24 has no less than two sets of cavities 25. Each cavity 25 has a spring 26. The upper and lower ends of the spring 26 are connected to the bottom surface of the cover plate 2 and the top surface of the pressure plate 23, respectively. When the two sets of cover plates 2 are closed, the pressure plate 23 can contact the top of the item and squeeze the spring 26 and the buffer block 24. The rebound force presses down on the item and fixes it to prevent it from being damaged by vibration.

[0026] The working principle is as follows:

[0027] In use, the two sets of cover plates 2 can be unfolded, and the items can be placed inside the box 1. The bottom of the items contacts and presses down on the contact plate 123. The items are cushioned and supported by the buffer pad 122 and the support base 121, and limited by the friction plate 11 on the inside of the box 1. Then the two sets of cover plates 2 are closed, and the pressure plate 23 can contact the top of the items and squeeze the spring 26 and the buffer block 24. The rebound force presses down on the items to fix them and prevents the items from being damaged by vibration during transportation and handling.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
