[0005] According to the utility model, a seismic buffering pearl cotton pad comprises a cotton pad body, which comprises a shock-absorbing layer, a pearl cotton surface layer arranged on the upper surface of the shock-absorbing layer, and a pearl cotton bottom layer arranged on the lower surface of the shock-absorbing layer; the shock-absorbing layer is provided with a first air cavity along the depth direction, a honeycomb structure is formed in the first air cavity, the honeycomb structure has a plurality of openings arranged in a honeycomb, a second air cavity is formed between the openings and the pearl cotton surface layer and the pearl cotton bottom layer, and an airway for airflow is provided between adjacent second air cavities; a placement groove for placing articles is provided on the upper surface of the pearl cotton surface layer, a plurality of first through holes connected to the second air cavity are provided on the pearl cotton surface layer along the periphery of the placement groove, and a plurality of second through holes connected to the first through holes are provided on the pearl cotton bottom layer.

[0006] Compared with the existing technology, the material of the pearl cotton surface layer itself can buffer the impact force to a certain extent, and then cooperate with the shock-absorbing layer to reduce shock, thereby improving the shock-absorbing effect of the cotton pad body. A second air cavity is arranged on the through opening, which can not only form a sufficient air cavity for the shock-absorbing layer to reduce shock, but also support the first air cavity, thereby improving the stability inside the first air cavity.

[0007] Preferably, an air cushion for wrapping the transported items is provided in the placement slot.

[0008] In the utility model, the air cushion is provided to protect the precision instrument placed in the slot again, thereby improving the shock absorption capacity of the cotton pad body.

[0009] Preferably, a plurality of engaging grooves are provided on both sides of the inner wall of the placement groove, and engaging blocks corresponding to the plurality of engaging grooves are provided on both sides of the outer wall of the air cushion, and a glue layer is provided at the engaging positions of the engaging grooves and the engaging blocks.

[0010] In the utility model, the clamping groove and the clamping block are clamped and bonded, so that the stability of the air cushion being fixed on the pearl cotton surface layer is improved.

[0011] Preferably, the cotton pad body further comprises a reinforcing layer arranged between the pearl cotton bottom layer and the shock-absorbing layer, the reinforcing layer is made of composite elastic fibers, and the fibers are distributed in a mesh shape.

[0025] Through the above structure, the object to be protected is placed in the placement groove 111. When the pearl cotton surface layer 110 is subjected to external impact, the pearl cotton surface layer 110 will squeeze the shock-absorbing layer 120, and the second air cavity 230 inside the first air cavity 210 will be compressed. The gas inside the second air cavity 230 flows out from the first through hole 112 on the pearl cotton surface layer 110 and the second through hole 320 on the pearl cotton bottom layer 130 through the air channel 310, thereby shock-absorbing the impact force on the pearl cotton surface layer 110. When the side wall of the pearl cotton surface layer 110 is impacted, When the first through hole 112 is deformed under the impact of external force, the lateral impact force on the cotton pad body 100 is reduced. Compared with the prior art, the material of the pearl cotton surface layer 110 itself can buffer the impact force to a certain extent, and then cooperate with the shock-absorbing layer 120 to reduce shock, thereby improving the shock-absorbing effect of the cotton pad body 100. A second air cavity 230 is arranged on the through hole 220, which can form an air cavity sufficient for the shock-absorbing layer 120 to reduce shock, and can also support the first air cavity 210, thereby improving the stability inside the first air cavity 210.

[0026] Combination Figure 1-2 As shown, in this embodiment, an air cushion 140 for wrapping transported items is provided in the placement groove 111; a plurality of engaging grooves 240 are provided on both sides of the inner wall of the placement groove 111, and engaging blocks 250 corresponding to the plurality of engaging grooves 240 are provided on both sides of the outer wall of the air cushion 140, and a glue layer is provided at the engaging positions of the engaging grooves 240 and the engaging blocks 250.

[0027] Through the above structure, the air cushion 140 can further protect the precision instrument in the placement groove 111, thereby improving the shock absorption ability of the cotton pad body 100; at the same time, the snap-fit ​​groove 240 and the snap-fit ​​block 250 are snap-fitted and adhered to improve the stability of the air cushion 140 fixed on the pearl cotton surface layer 110.

[0028] Combination Figure 1 and Figure 4 As shown, in this embodiment, a buffer layer 410 is provided on the lower surface of the pearl cotton bottom layer 130, the buffer layer 410 is wavy, and a third air cavity 420 is formed between the buffer layer 410 and the pearl cotton bottom layer 130; the second through hole 320 is connected to the third air cavity 420.

[0029] Through the above structure, when the pearl cotton bottom layer 130 is subjected to impact force, the buffer layer 410 contacts and compresses the third air cavity 420, thereby reducing the impact force; at the same time, the second through hole 320 is connected with the third air cavity 420, and the third air cavity 420 will flow into the shock-absorbing layer 120 through the second through hole 320 during the compression process, and then flow out through the first through hole 112, thereby avoiding the vibration caused by the rapid rebound of the shock-absorbing layer 120 after the impact force ends.

[0030] Combination Figure 1 and Figure 3 As shown, in this embodiment, the cotton pad body 100 further includes a reinforcing layer 150 disposed between the pearl cotton bottom layer 130 and the shock-absorbing layer 120. The reinforcing layer 150 is made of composite elastic fibers, and the fibers are distributed in a mesh shape.

[0031] Through the above structure, the shock absorbing ability of the cotton pad body 100 can be improved while the ventilation effect of the second through hole 320 is not affected.

[0032] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on one or several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.
