Description

Technical Field

[0001] This utility model relates to the field of pearl cotton technology, and in particular to a shock-absorbing pearl cotton. Background Technology

[0002] Shock-absorbing pearl cotton (EPE pearl cotton) is an environmentally friendly physical foaming material with polyethylene as the base material. It is mainly used for shock protection in packaging, transportation and other scenarios. Shock-absorbing pearl cotton is made of low-density polyethylene resin through physical foaming process, forming a large number of independent bubble structures. It belongs to non-crosslinked closed-cell materials.

[0003] Traditional shock-absorbing pearl cotton is subjected to compression and collision when carrying transported goods. Under the pressure and impact of the transported goods, the shock-absorbing pearl cotton will deform to a certain extent. When reusing the deformed shock-absorbing pearl cotton, it is necessary to first stretch the deformed and bent pearl cotton to straighten it and fix it for a period of time. This has a great drawback in the reuse of shock-absorbing pearl cotton. It is necessary to manually stretch the deformed and bent pearl cotton and fix it for a period of time before it can be reused, which affects the reuse effect of the shock-absorbing pearl cotton. Therefore, in order to solve this problem, a new type of shock-absorbing pearl cotton is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a shock-absorbing pearl cotton.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A shock-absorbing pearl cotton, comprising a shock-absorbing sponge layer, wherein pearl cotton layers are provided on both the upper and lower sides of the shock-absorbing sponge layer;

[0007] Rubber connecting pieces are provided on both sides of the shock-absorbing sponge layer. Several hollow holes are opened in the shock-absorbing sponge layer. Several rubber elastic ropes are arranged between two rubber connecting pieces. The rubber elastic ropes are located in the hollow holes respectively, and the rubber elastic ropes are in a taut state.

[0008] Preferably, the shock-absorbing sponge layer has several cavities, and rubber springs are installed in the cavities.

[0009] Preferably, plastic connecting pieces are installed on both the top wall and the bottom wall of the cavity, and the two ends of the rubber spring are respectively connected to the two plastic connecting pieces.

[0010] Preferably, the rubber connecting piece has several adhesive blocks on the side near the shock-absorbing sponge layer, and the end of the rubber elastic rope is connected to the adhesive blocks.

[0011] Preferably, a shock-absorbing rubber layer is provided on the side of the pearl cotton layer away from the shock-absorbing sponge layer, and the shock-absorbing rubber layer is adhered to the side of the pearl cotton layer away from the shock-absorbing sponge layer.

[0012] Preferably, a flame-retardant layer is bonded to the side of the shock-absorbing rubber layer away from the shock-absorbing sponge layer, and the flame-retardant layer is adhesive flame-retardant cotton.

[0013] Preferably, a waterproof film layer is adhered to the side of the flame-retardant layer away from the shock-absorbing sponge layer, and the waterproof film layer is a polytetrafluoroethylene microporous membrane.

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

[0015] 1. In this utility model, the rubber elastic rope can be used to reset the shock-absorbing sponge layer, pearl cotton layer, and shock-absorbing rubber layer, thereby restoring the bent and deformed shock-absorbing sponge layer, pearl cotton layer, and shock-absorbing rubber layer. There is no need for manual reset of the bent and deformed shock-absorbing sponge layer, pearl cotton layer, and shock-absorbing rubber layer, thus improving the reusability and reuse effect of this device.

[0016] 2: In this utility model, the rubber spring inside the shock-absorbing sponge layer can provide support for the shock-absorbing sponge layer, so as to avoid the shock-absorbing sponge layer being difficult to return to its original position when it is subjected to impact force due to its own softness. The rubber spring can be used to support the shock-absorbing sponge layer to assist in its return to its original position, and prevent the shock-absorbing sponge layer from being crushed by impact force on both sides at the same time.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 A shock-absorbing pearl cotton, comprising a shock-absorbing sponge layer 1, with pearl cotton layers 3 on both the upper and lower sides of the shock-absorbing sponge layer 1.

[0024] Rubber connecting pieces 2 are provided on both sides of the shock-absorbing sponge layer 1. Several hollow holes 7 are opened in the shock-absorbing sponge layer 1. Several rubber elastic ropes 8 are provided between the two rubber connecting pieces 2. The rubber elastic ropes 8 are located in the hollow holes 7 respectively, and the rubber elastic ropes 8 are in a taut state.

[0025] As a technical optimization of this utility model, a plurality of cavities 9 are provided in the shock-absorbing sponge layer 1, and rubber springs 10 are installed in the cavities 9; plastic connecting pieces 11 are installed on the top wall and bottom wall of the cavity 9, and the two ends of the rubber spring 10 are respectively connected to two plastic connecting pieces 11. The cavity 9 can facilitate the installation of the rubber spring 10 in the shock-absorbing sponge layer 1 and can provide an installation position for the rubber spring 10. The plastic connecting pieces 11 can facilitate the connection of the two ends of the rubber spring 10 to the shock-absorbing sponge layer 1.

[0026] As a technical optimization of this utility model, a plurality of adhesive blocks 12 are provided on the side of the rubber connecting piece 2 near the shock-absorbing sponge layer 1, and the end of the rubber elastic rope 8 is connected to the adhesive block 12; a shock-absorbing rubber layer 4 is provided on the side of the pearl cotton layer 3 away from the shock-absorbing sponge layer 1, and the shock-absorbing rubber layer 4 is adhered to the side of the pearl cotton layer 3 away from the shock-absorbing sponge layer 1; a flame-retardant layer 5 is adhered to the side of the shock-absorbing rubber layer 4 away from the shock-absorbing sponge layer 1, and the flame-retardant layer 5 is adhesive flame-retardant cotton; a waterproof film layer 6 is adhered to the side of the flame-retardant layer 5 away from the shock-absorbing sponge layer 1, and the waterproof film layer 6 is a polytetrafluoroethylene microporous membrane; the adhesive blocks 12 facilitate the connection between the rubber elastic rope 8 and the rubber connecting piece 2, and the waterproof film layer 6 provides waterproof function for this device, preventing the device from absorbing water and getting damp when it comes into contact with water, while ensuring the dryness of the device and preventing the device from getting damp and moldy.

[0027] When this utility model is in use, if it is necessary to support the transported goods, the device is placed below or to the side of the transported goods to be supported, and the device can provide shock absorption and protection for the transported goods.

[0028] The shock-absorbing sponge layer 1, pearl cotton layer 3, and shock-absorbing rubber layer 4 provide cushioning for the transported goods, thereby improving the shock absorption effect, reducing the collision force generated during transportation, and enhancing the protection of the transported goods.

[0029] By utilizing the flame-retardant properties of the flame-retardant layer 5, the device can be prevented from being ignited by external fires. The flame-retardant layer 5 can also provide flame-retardant effects to the shock-absorbing sponge layer 1, pearl cotton layer 3, and shock-absorbing rubber layer 4, preventing them from being ignited by external fire sources and causing a larger fire. At the same time, it also prevents external fire sources from igniting the transported goods protected by the device and causing them to catch fire, thereby improving the protection of the transported goods protected by the device.

[0030] When this device is subjected to compression or impact from the transported object, the impact force is transmitted to the shock-absorbing sponge layer 1, pearl cotton layer 3, and shock-absorbing rubber layer 4. The shock-absorbing sponge layer 1, pearl cotton layer 3, and shock-absorbing rubber layer 4 buffer and weaken the impact force, reducing the deformation of the device. When the residual impact force deforms the shock-absorbing sponge layer 1, pearl cotton layer 3, and shock-absorbing rubber layer 4, the deformed shock-absorbing sponge layer 1, pearl cotton layer 3, and shock-absorbing rubber layer 4 can cause the taut rubber elastic rope 8 to deform as well. Since the rubber elastic rope 8 is taut, after it deforms along with the shock-absorbing sponge layer 1, pearl cotton layer 3, and shock-absorbing rubber layer 4, the impact force of the transported object on the shock-absorbing sponge layer 1, pearl cotton layer 3, and shock-absorbing rubber layer 4 disappears. The bent rubber elastic rope 8 then begins to return to its original position under its own elastic restoring force. And after several rubber elastic ropes 8... During the reset process, the deformed shock-absorbing sponge layer 1, pearl cotton layer 3, and shock-absorbing rubber layer 4 are reset together, thereby passively resetting the bent and deformed shock-absorbing sponge layer 1, pearl cotton layer 3, and shock-absorbing rubber layer 4. This resets the shock-absorbing sponge layer 1, pearl cotton layer 3, and shock-absorbing rubber layer 4 that have been deformed and bent by the impact of the transported object. It eliminates the need for manual straightening and shaping of the shock-absorbing sponge layer 1, pearl cotton layer 3, and shock-absorbing rubber layer 4. The rubber elastic rope 8 can reset the shock-absorbing sponge layer 1, pearl cotton layer 3, and shock-absorbing rubber layer 4, thus improving the reusability and reuse effect of the device.

[0031] Furthermore, when the transported object impacts the shock-absorbing sponge layer 1, pearl cotton layer 3, and shock-absorbing rubber layer 4, the rubber spring 10 inside the shock-absorbing sponge layer 1 can also provide a buffering effect for the shock-absorbing sponge layer 1, pearl cotton layer 3, and shock-absorbing rubber layer 4, reducing the impact force on them. At the same time, utilizing the elastic restoring force of the rubber spring 10 itself, the shock-absorbing sponge layer 1, pearl cotton layer 3, and shock-absorbing rubber layer 4, which have been deformed by the impact force, can also follow the rubber spring 10 to perform a restoring movement under the action of the rubber spring 10, assisting the deformed and bent shock-absorbing sponge layer 1, pearl cotton layer 3, and shock-absorbing rubber layer 4 to restore their original position. In addition, the rubber spring 10 inside the shock-absorbing sponge layer 1 can provide support for the shock-absorbing sponge layer 1, preventing the shock-absorbing sponge layer 1 from being difficult to restore its original position due to its softness. The support of the rubber spring 10 for the shock-absorbing sponge layer 1 can assist in the restoration of the shock-absorbing sponge layer 1, preventing the shock-absorbing sponge layer 1 from being crushed by the impact force on both sides at the same time.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
