Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, an antistatic shoe, including sole 1 and upper of a shoe 3, a serial communication port, the bottom fixed connection of upper of a shoe 3 is on the top surface of sole 1, shock attenuation chamber 2 has been seted up on sole 1, it has a plurality of supporting box 4 that the equidistance set up to bond on the interior diapire of shock attenuation chamber 2, the activity hole has been seted up on the roof of supporting box 4, shock attenuation post 8 of perpendicular setting has been cup jointed in the activity hole, the bottom of shock attenuation post 8 extends to the inside of supporting box 4 and the limiting plate 7 that fixed connection has the level to set up, limiting plate 7 activity is cup jointed on the inside wall of supporting box 4, the diapire of limiting plate 7 is connected with spring 6 with the interior diapire of supporting box 4, the top of shock attenuation post 8 extends to the top of supporting box 4 and fixedly connected with backup pad 9, backup pad 9 bonds on the interior.

In this embodiment, upper of a shoe 3 includes cloth layer 10 and antistatic backing 11, the bottom bonding of cloth layer 10 is on the top surface of sole 1, antistatic backing 11 bonds at cloth layer 10's internal surface, antistatic backing 11 bonds on sole 1's top surface, sole 1 and antistatic backing 11 are made by PU expanded material, the size of the 8 outer lanes of shock attenuation post and the size looks adaptation of the movable orifice on the supporting box 4, the size of limiting plate 7 and the size looks adaptation of the inside wall of supporting box 4, be provided with a plurality of bumps 5 on sole 1's the bottom surface, bump 5 is made by PU expanded material.
