[0017] The utility model is described in detail below in combination with the drawings and examples.

[0018] Buffer type mela sheet, such as Figure 1 、 Figure 2 and Figure 3As shown, it comprises a contact layer 1, the bottom of the contact layer 1 is fixedly connected with a first buffer sponge 2, the bottom of the first buffer sponge 2 is fixedly connected with a fixed layer 3, the bottom of the fixed layer 3 is fixedly connected with a plurality of reinforcing strips 6, the bottom of the fixed layer 3 is also provided with a second buffer sponge 4, the bottom of the second buffer sponge 4 is fixedly connected with a wear-resistant layer 5, a plurality of perforations one 301 are formed on the fixed layer 3, a plurality of perforations two 101 are formed on the contact layer 1, a pulling rope 7 is arranged in the perforations one 301 and the perforations two 101, the pulling rope 7 is in contact with the reinforcing strips 6, the two ends of the pulling rope 7 are fixedly connected with a fixing sheet 8, the end surface of the fixing sheet 8 is provided with an adhesive and a release paper, in the case of a relatively narrow environment, the pulling rope 7 can be pulled upwards, the pulling rope 7 is in contact with the reinforcing strips 6 and applies pressure to them, so that the first buffer sponge 2 is subjected to pressure and becomes flatter, which facilitates the insertion of the Mylar sheet into contact with the product and avoids the need to cut the sponge before installing the Mylar sheet due to the gap between the products.

[0019] As shown in Figure 1 , Figure 2 and Figure 3 , the contact layer 1 and the fixed layer 3 are made of PVC material and are formed by a double-axis stretching machine, the PVC material has good insulation and corrosion resistance, the perforations two 101 on the contact layer 1 and the perforations one 301 on the fixed layer 3 can be formed by a laser perforating machine or a stamping method, the perforations one 301 are close to the edge of the fixed layer 3, the end surface of the fixed layer 3 is fixedly connected with a plurality of reinforcing strips 6, the reinforcing strips 6 are made of PET material, the PET material has the characteristics of high strength and high hardness, when the pulling rope 7 is in contact with the reinforcing strips 6, the first buffer sponge 2 is deformed by the reinforcing strips 6 with high hardness, and the arrangement of a plurality of reinforcing strips 6 can make the deformation of the first buffer sponge 2 more uniform, the reinforcing strips 6 are fixed to the bottom of the fixed layer 3 by gluing.

[0020] As shown in Figure 1 , Figure 2 and Figure 3As shown, the wear-resistant layer 5 is also made of PVC material, and the surface is coated with a wear-resistant coating. The wear-resistant layer 5, as a layer directly contacting with external substances, has excellent wear resistance, which can prolong the service life of the Mylar sheet as a whole and further improve the protection effect of the Mylar sheet on the product. The second buffer sponge 4 is arranged between the wear-resistant layer 5 and the fixed layer 3, and the density of the second buffer sponge 4 is greater than that of the first buffer sponge 2. The first buffer sponge 2 and the second buffer sponge 4 with different densities can cope with different impact forces. That is, under the condition of smaller impact force, the first buffer sponge 2 with lower density deforms greatly to absorb part of the impact force. Under the condition of larger impact force, both the first buffer sponge 2 and the second buffer sponge 4 deform greatly to absorb more impact force, so that the protection effect of the Mylar sheet on the product is better. The first buffer sponge 2 and the second buffer sponge 4 are fixed on the contact layer 1, the fixed layer 3 and the wear-resistant layer 5 by means of glue.

[0021] As shown in Figure 1 , Figure 2 and Figure 3 , the height of the second buffer sponge 4 is greater than the height of the reinforcing strip 6. The second buffer sponge 4 forms a space between the fixed layer 3 and the wear-resistant layer 5 for the movement of the pulling rope 7. It should be noted that the midpoint of the horizontal section of the fixed layer 3, the midpoint of the horizontal section of the first buffer sponge 2 and the midpoint of the horizontal section of the second buffer sponge 4 are on the same vertical line, and the horizontal section shape of the first buffer sponge 2 is consistent with the horizontal section shape of the fixed layer 3. The size of the horizontal section of the first buffer sponge 2 is smaller than the size of the horizontal section of the fixed layer 3. The arrangement of this structure can make the force applied by the reinforcing strip 6 and the fixed layer 3 on the first buffer sponge 2 uniform during the pulling process of the pulling rope 7, ensuring the stability and convenience of the Mylar sheet during installation.

[0022] As shown in Figure 1 , Figure 2 and Figure 3 , the two ends of the pulling rope 7 are provided with fixing pieces 8, and the fixing pieces 8 are provided with adhesive and release paper. After placing the Mylar sheet, the release paper is torn off and the fixing pieces 8 are adhered to the surface of the product or other objects through the adhesive, completing the fixation of the Mylar sheet. At the same time, this method can flexibly control the shape of the first buffer sponge 2, ensuring that the first buffer sponge 2 can stably play a buffering role. Preferably, the pulling rope 7 can be made of nylon rope, which has good wear resistance and structural strength, and can ensure the service life of the pulling rope 7 as a whole.

[0023] The above merely is preferred implementation manner of the present application, the protection scope of the present application is not only limited to the above examples, and belongs to the technical scheme under the idea of the present application all belongs to the protection scope of the present application. It should be pointed out that, for ordinary skilled person in the art, under the premise of not departing from the principle of the present application, some improvements and decorations, these improvements and decorations should also be considered as the protection scope of the present application.
