A kind of labor insurance shoe that prevents subsidence

Abstract

The invention relates to shoes, and specifically discloses safety shoes with a sinking prevention function. Each shoe comprises a shoe sole and a shoe body fixed on the shoe sole, each shoe sole is internally and fixedly provided with a control air cylinder with an opening and at least one slide-out air cylinder, each slide-out air cylinder is internally provided with a slide-out piston capable ofsliding along the inner wall of the slide-out air cylinder, each slide-out piston partitions the corresponding slide-out air cylinder into a slide-out cavity and a retraction cavity and is horizontally and fixedly provided with a sliding board, and the end, away from the corresponding slide-out piston, of each sliding board penetrates through the side wall of the corresponding retraction cavity and the corresponding shoe sole; the opening of the control air cylinder faces downwards, and the control air cylinder is communicated with the slide-out cavities; each shoe body comprises a shoe upper, a vamp and a shoe tip which are fixedly connected, each vamp is internally provided with a cavity, a plurality of air bags capable of automatically restoring an original shape are placed in the cavities, each air bag is provided with a through hole, and the cavities are communicated with the retraction cavities. According to the scheme, the safety shoes can slow down sinking of shoe bodies.

Description

technical field [0001] The invention relates to a shoe, in particular to a labor protection shoe. Background technique [0002] Labor insurance shoes are a kind of shoes that have a safety protection effect on the feet. In order to play a protective role, the surface of the labor insurance shoes will be coated with a special protective coating. In some smelting plants, the distance between different smelting workshops is large, and there is generally no shelter above the open space between the workshops, so when it rains, the rainwater directly falls on the open space. Because the transport vehicles transporting ore and workpieces often pass through the open space, there are often pits pressed out by the transport vehicle on the open space. During the transportation process, the soil attached to the ore will also fall to the ground, and the contact between the soil and rainwater will form mud. Workers It is easy to fall into the mud when passing through the pits. The mud st...

Problems solved by technology

Because the transport vehicles transporting ore and workpieces often pass through the open space, there are often pits pressed out by the transport vehicle on the open space, and during the transportation process, the soil attached to the ore will also fall to the ground, and the soil will form mud when it contacts with rainwater. It is easy to fall into the mud when passing through the pits. The mud sticks to the safety shoes and is difficult to clean after air-drying. It is also easy to damage the special coating on the upper of the safety shoes during cleaning, making the safety shoes lose their protective effect.

Secondly, after the labor insurance shoes sink into the mud, the mud is discharged from the sole under pressure. When the shoes are lifted up, there is an adsorption force between the shoes and the mud at the bottom, which will increase the pulling force required to lift the shoes, and then increase the worker's walking. resistance
