[0002] Under normal circumstances, the human body will generate static electricity due to friction with air or other substances during daily activities. In a specific working environment, such as an electronic equipment production line, if this static electricity is not effectively controlled, it may cause damage to sensitive electronic equipment. Anti-static shoes are a kind of work shoes worn in production workshops and advanced laboratories of microelectronic industries such as electronic semiconductor devices, electronic computers, electronic communications and integrated circuits to reduce or eliminate the hazards of static electricity. The principle of anti-static shoes is achieved through anti-static materials in the sole and upper. The sole includes an outsole and a midsole. In the prior art, anti-static requirements are often achieved by adding anti-static liquid to the rubber outsole. However, when making the midsole, it is difficult to produce an anti-static midsole by adding anti-static liquid. This is because the addition of anti-static liquid to the EVA midsole, PU midsole, TPU midsole, and rubber foam midsole during the production process will affect the material function, making it difficult to master the function and material properties, and the processing cycle is long, which increases the production cost, which brings great trouble to the company.

[0020] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.
[0021] Example 1
[0022] like Figure 1 , Figure 2 and Figure 3As shown, the new anti-static functional structure sole of the utility model includes an anti-static belt 2, a midsole 3 and an outsole 4, one end of the anti-static belt 2 is connected to the upper surface of the midsole 3, and the other end is connected to the lower surface of the midsole 3, the outsole 4 is fixedly connected to the lower surface of the midsole 3 and connected to the anti-static belt 2, and the outsole 4 is made of anti-static material.
[0023] Example 2
[0024] On the basis of Example 1, Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, a strip hole 1 is provided on the midsole 3, and the strip hole 1 is located at the bending part of the forefoot. The anti-static belt 2 is passed through the strip hole 1. Specifically, one end of the anti-static belt 2 is fixedly connected to the upper surface of the midsole 3, and the other end is fixedly connected to the lower surface of the midsole 3 after passing through the strip hole 1, that is, one end of the anti-static belt 2 is located between the outsole 4 and the midsole 3.
[0025] The outsole 4 is made of antistatic rubber material, and the midsole 3 is made of any one of EVA material, PU material, TPU material, and rubber foam material. The outsole 4 and the midsole 3 are fixed together by adhesive, and the adhesive includes latex glue, polyurethane adhesive, etc.
[0026] In this embodiment, the antistatic belt 2 is rectangular and 20 cm long, and the length of the strip hole 1 must be greater than the width of the antistatic belt 2, so as to ensure that the antistatic belt 2 passes through the strip hole 1 smoothly. When used, the size of the antistatic belt 2 and the size of the strip hole 1 can be adjusted according to actual conditions.
[0027] The utility model bonds the antistatic tape 2 between the upper surface of the midsole 3 and the lower surface of the midsole 3, so that the midsole 3 can have an antistatic function without adding antistatic liquid, and the antistatic tape 2 is arranged on the upper surface of the midsole 3 and the lower surface of the midsole 3 for a certain length. In this embodiment, the arrangement length of the antistatic tape 2 on the upper surface and the lower surface of the midsole 3 is 10 cm, which can ensure that the antistatic tape 2 is in full and close contact with the upper surface of the midsole 3 and the lower surface of the midsole 3, so that static electricity can be better transferred, thereby ensuring the antistatic performance of the midsole 3 with the antistatic tape 2.

[0030] The working principle of the utility model is as follows: static electricity of the human body is transferred from the sole to the midsole 3, and then from the midsole 3 to the antistatic belt 2, and the antistatic belt 2 transfers the static electricity to the outsole 4. Since the outsole 4 has antistatic properties, the static electricity will be introduced into the ground through the outsole 4.
