Description

Technical Field

[0001] The utility model relates to the technical field of sponges, in particular to an antistatic sponge. Background Art

[0002] Antistatic sponge is a material with special functions, which is widely used in electronic product packaging, precision instrument protection and other fields that require antistatic protection. Its main function is to use the softness and elasticity of the sponge to provide good buffering and shock absorption effects to prevent static electricity from damaging sensitive electronic components and equipment. The porous structure of the sponge can effectively absorb and disperse external impact forces, reduce the direct impact of vibration on internal products, and thus play a protective role.

[0003] However, traditional anti-static sponges also have certain limitations in actual use. The main problem is that the sponge mainly relies on its own physical properties to absorb energy and reduce shock during the buffering process. This method is prone to deformation or damage to the sponge structure when facing a large impact force or long-term use, thereby losing the buffering effect. Especially when dealing with high-value, high-precision electronic products, it is often difficult to completely avoid breakage and damage to the product by simply relying on the characteristics of the sponge for protection. In addition, the sponge has limited compressive strength and recovery ability, and is prone to fatigue and performance degradation after repeated use, further increasing the uncertainty of product protection.

[0004] Therefore, those skilled in the art have just proposed a kind of antistatic sponge. Utility Model Content

[0005] The utility model discloses an antistatic sponge, aiming to solve the technical problems in the background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An antistatic sponge comprises a sponge block, wherein buffer nails are arranged at equal distances on one side of the sponge block, a bonding block is arranged on the side of the sponge block away from the buffer nails, and a rubber strip is arranged on the bonding block;

[0008] The sponge block is composed of a bonding layer, a pore layer, a connecting layer, a shock absorbing layer and a fusion layer;

[0009] The buffer nail is composed of a cushion block, a pressure-bearing layer, a high-elastic layer, a rebound layer and a contact layer.

[0010] In a preferred solution, the bonding layer is made of antistatic polyurethane material, and the thickness of the antistatic polyurethane material is set to five millimeters.

[0011] In a preferred solution, the porous layer is made of antistatic polyurethane material, the thickness of the antistatic polyurethane material is set to eight millimeters, and the pores in the porous layer are larger than the pore size of the bonding layer.

[0012] In a preferred solution, the connection layer is made of silicone material, the connection layer is connected to the bonding block, and the thickness of the silicone is set to three millimeters.

[0013] In a preferred solution, the shock-absorbing layer is made of antistatic EVA material, and the thickness of the antistatic EVA material is set to ten millimeters.

[0014] In a preferred solution, the fusion layer and the cushion block are both made of antistatic thermoplastic polyurethane material, and the thickness of the antistatic thermoplastic polyurethane is set to six millimeters.

[0015] In a preferred solution, the pressure-bearing layer is configured as antistatic high-elastic foam, and the thickness of the antistatic high-elastic foam is configured as four millimeters.

[0016] In a preferred solution, the high elastic layer is configured as an antistatic high-density memory foam, and the thickness of the antistatic high-density memory foam is configured as twelve millimeters.

[0017] In a preferred solution, the resilience layer is set to be antistatic soft PVC, and the thickness of the antistatic soft PVC is set to two millimeters.

[0018] In a preferred solution, the contact layer is configured as high-density rubber and has a thickness of four millimeters.

[0019] The antistatic sponge provided by the utility model has the following advantages:

[0020] The dual protection design of buffer nails and sponge blocks effectively solves the limitation of traditional anti-static sponges that rely on a single physical property during the buffering process. First, the bonding block is connected to the installation position through a rubber strip to ensure the correct installation of the sponge block so that it contacts the product. The sponge block consists of a bonding layer, a pore layer, a connection layer, a shock-absorbing layer and a fusion layer, providing a multi-level protection effect. The buffer nail, as a round nail-shaped structure, contacts the product and plays the role of the first layer of protection. When the buffer nail is compressed, the sponge block provides a second layer of protection to further absorb and disperse the impact force. Through the dual protection design, the impact force of the product when it is hit is significantly reduced, preventing the deformation and performance degradation of traditional sponges due to long-term use or high-intensity impact. At the same time, all protective layers are made of anti-static materials to effectively prevent static electricity accumulation and damage to the product, further improving the safety and durability of the product. This not only improves the buffering effect, but also increases the durability of the overall structure, ensuring that the product is more reliably protected in various usage environments.

The buffer nail 2, as a round nail-shaped structure, is in contact with the product and plays the role of the first layer of protection. When the buffer nail 2 is compressed, the sponge block 1 provides a second layer of protection to further protect the product from impact damage. The advantage of this setting is that the dual protection design of the buffer nail 2 and the sponge block 1 effectively reduces the impact force of the product when it is hit, thereby improving the safety and durability of the product.
