In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] A type of antistatic safety shoe, such as Figures 1-3 As shown, the shoe includes a sole 1, which comprises, from bottom to top, an abrasion-resistant layer 2, a cushioning layer 3, and a conductive layer 4. The layers are tightly connected by adhesive. The abrasion-resistant layer 2 is made of highly abrasion-resistant rubber and contains several abrasion-resistant particles. These particles are evenly distributed within the abrasion-resistant layer 2, enhancing its overall abrasion resistance and making the safety shoe more durable. The cushioning layer 3 is made of polyurethane foam, which is elastic and easy to mold, giving the sole 1 good cushioning function. The conductive layer 4 is made of conductive rubber, which contains conductive fibers that interweave to form a conductive network, ensuring both conductivity and a certain degree of toughness to maintain structural stability.

[0021] Specifically, the conductive layer 4 has an installation groove 41, and a metal conductive sheet 5 is installed in the installation groove 41. The wear-resistant layer 2 has a grounding device 8 embedded in the center of the sole 1. The metal conductive sheet 5 is electrically connected to the conductive layer 4 and the grounding device 8 through conductive wires 6. The buffer layer 3 has several buffer grooves 31 evenly distributed. The metal conductive sheet 5 is fixedly installed with a column facing the several buffer grooves 31. The buffer layer 3 has buffer components installed in the several buffer grooves 31.

[0022] Practical effect: The metal conductive sheet 5 and conductive wire 6 of the sole 1 form a continuous conductive network, and together with the grounding device 8, the static electricity of the human body is quickly conducted to the ground, which effectively avoids the risk of motor or spark caused by static electricity accumulation. In addition, the conductive layer 4 is separated from the wear-resistant layer 2 by the buffer layer 3 to prevent damage to the metal conductive sheet 5 in the conductive layer 4, thereby affecting the conductivity.

[0023] like Figures 1-3 As shown, the cushioning component includes a spring 7, with both ends of the spring 7 abutting against the bottom of the cushioning groove 31 and the bottom of the metal conductive sheet 5, respectively. The spring 7 provides good cushioning performance when the safety shoe is worn, as the wearer walks. Through the synergistic effect of the metal conductive sheet 5, the upright, and the spring 7, the structural stability is enhanced, and the deformation of the metal conductive sheet 5 is prevented.

[0024] like Figures 1-3 As shown, the grounding device 8 includes a grounding post 81 and a grounding wire 82. The grounding post 81 is embedded in the wear-resistant layer 2. The top of the grounding post 81 is connected to the conductive wire 6. The grounding wire 82 is fixedly connected to the grounding post 81 and extends to the heel of the shoe while adhering to the wear-resistant layer 2, ensuring that static electricity from the human body can be quickly conducted to the ground.

[0025] like Figures 1-3 As shown, it also includes an upper 9, which is sewn to the conductive layer 4 with stitching thread. A metal toe cap 91 is embedded in the upper 9, and a flexible conductive strip 10 is provided between the metal toe cap 91 and the metal conductive sheet 5. The metal toe cap 91 is electrically connected to the metal conductive sheet 5 through the flexible conductive strip 10. The metal toe cap 91 embedded in the upper 9 and the flexible conductive strip 10 added between the metal toe cap 91 and the metal conductive sheet 5 not only protects the wearer's feet but also further enhances the conductivity between the human body and the ground, ensuring the overall electrostatic protection effect of the safety shoe. Specifically, the stitching thread is made of conductive fiber twisting, which further enhances the connection between the upper 9 and the conductive layer 4 and reduces the generation of static electricity.

[0026] Manufacturing process: The wear-resistant layer 2 and the conductive layer 4 are mixed and formed by an open mill and molded. The cushioning layer 3 is foamed by a foaming agent. Then, glue is applied to the bonding area. After curing, the shoe upper 9 is sewn onto the conductive layer 4 using sewing thread. Finally, the safety shoe is tested to ensure the stability and conductivity of the connection of each component.
