Abstract

The utility model relates to static electricity discharging shoes; the top surface of a shoe sole is fixedly provided with a cushion layer, and the shoe sole is added with guide electrostatic agent in the raw material of plastic material. The shoe sole has static conductivity after shaping, and the top of the shoe sole is convexly provided with a conducting part with certain area and height. The symmetrical position of the cushion layer is provided with a hole, and the conducting part passes through the hole. The top of the conducting part is aligned to the top surface of the cushion layer. When the foot sole of human body contacts with the top of sole, the conducting part can be connected with ground for conduction. The static electricity can be removed. The utility model can reduce the injury of the human body and instrument and have the advantages of safe work, simple structure and less cost.

Description

Static electricity discharging shoes

The utility model relates to a kind of Static electricity discharging shoes, particularly relates to a kind of simple structure and can arrange the Static electricity discharging shoes of static.

The general PVC plastic shoes that uses the workplace, when dress or motion, produce friction and can produce static, and general PVC material is the good insulation performance body, so can't discharge too much static, and the static that human body itself and clothing friction are produced, whole being accumulated in the human body of meeting causes stress and muscle to relax, especially in high-volatile workplace, as gas station, solvent factory, because of the individual with the static value excess load, and form spark, be easy to cause danger.General e-factory if operating personnel institute static electrification is too much, also can cause damage to product.

As shown in Figure 1, 2, but be a kind of slippers of antistatic, set firmly a conducting element 1 in the sole outside, one end upwards bending extends a conduction junctor 2 to the sole end face, and picks out a lead 3 by this conduction junctor 2, and these conductor 3 other ends set firmly a setting element 4, utilize this setting element 4 to contact with the human foot, form grounded circuit, can get rid of static whenever and wherever possible, avoid human body or instrument to come to harm.

Though, but the slippers of above-mentioned antistatic can reach the purpose of getting rid of static, and member complexity and quantity are many, and this lead 3 has suitable length, can stretch out in beyond the human foot, be easy to by the foreign object hook, and tool are tripped danger.

The purpose of this utility model is to provide a kind of Static electricity discharging shoes, utilizes simple structure to reach to get rid of the purpose of static, and is not only easy to manufacture, and can not hindered by foreign object when wearing.

According to Static electricity discharging shoes of the present utility model, it it comprise a plastic material sole, a bed course and a vamp, be installed with bed course at this sole end face, form this vamp on every side, it is characterized in that: this sole increases static conducting agent in plastic material, the convex conducting portion that is provided with of this sole end face, and this bed course is provided with the hole with this conducting portion similar number, this hole is set in the outside of conducting portion, and the top end face of this conducting portion flushes with this bed course end face.

In Static electricity discharging shoes of the present utility model, the position of this conducting portion is at close this shoes tip of this sole.

Static electricity discharging shoes of the present utility model sets firmly a bed course at the sole end face, this sole increases static conducting agent in plastic material, has electrostatic conductiveness after making this Sole moulding, this sole end face upwards is convexly equipped with the conducting portion of a certain area of tool and height, the symmetric position place of this bed course then is provided with a hole, this conducting portion is located in this hole, the top end face of this conducting portion flushes with this conducting portion, when the human body sole contacts with the sole end face, utilize this conducting portion just can earth-continuity, and will be on one's body with static get rid of, not only can reduce human body, the injury of instrument and raising work safety, and simple structure can reduce cost.

Below by most preferred embodiment and accompanying drawing Static electricity discharging shoes of the present utility model is elaborated, in the accompanying drawing:

Fig. 1 is a kind of in the past schematic perspective view of antistatic slippers.

Fig. 2 is the profile of being done along the II-II line of Fig. 1.

Fig. 3 is the schematic perspective view of the utility model preferred embodiment.

Fig. 4 is the profile of being done along the IV-IV line of Fig. 3.

Shown in Fig. 3,4, the Static electricity discharging shoes of the utility model embodiment comprises a sole 10, a bed course 20 and a vamp 30, sets firmly bed course 20 at these sole 10 end faces, and forms this vamp 30 on every side.

This sole 10 is with the polyvinyl chloride powder (PVC) of the degree of polymerization 1000 units, plasticizer several materials such as dioctyl phthalate dioctyl ester (being called for short DOP), blowing agent, epoxy plasticizer, electrostatic agent, interior lubrication prescription, outer lubrication prescription, calcium carbonate how; allocate according to standard number; after moulding grain mechanism grain; again in mould is injected in the make-up machine melting and moulding; utilize the effect of electrostatic agent; and have electrostatic conductiveness, and the antistatic resistance (R) of this sole 10 is reduced to 1.0*10 after test ⁹Ω/CM.Near shoes tip, upwards be convexly equipped with a tool suitably height and rounded conducting portion 11 at this sole 10.

These bed course 20 thickness are identical with the height of this conducting portion 11, when these sole 10 moulding, directly be installed in this sole 10 end faces, and this conducting portion 11 of symmetry also is provided with a hole 21 that is circular hole, this hole 21 can be set in the outside of this conducting portion 11, and the top end face of this conducting portion 11 flushes with these bed course 20 end faces.

This vamp 30 is when these sole 10 castings with member was identical in the past, and these vamp 30 bottom peripheral edge are cemented on this sole 10, the human foot is worn and locatees.

Above-mentioned structure, change the footwear sole construction composition made from polyvinyl chloride (PVC) material originally, and when the human body sole pastes when touching on this conducting portion 11, can with on one's body with unnecessary static import immediately underground, make on one's body with static value can maintain in the safe range.

The position that this conducting portion 11 is provided with is near shoes tip at this sole 1, no matter can make the human body sole anterior under which kind of wears state because be arranged on this position, all contact with this conducting portion 11, when for example static, human body is stepped on crouching appearance or walking, and present embodiment is made about 13-15mm with this conducting portion 11, can not influence this bed course 20 provides the human foot anti-slip effect, and the number of this conducting portion 11 also can be set up into two (present embodiment only is provided with one).

In sum, when wearing Static electricity discharging shoes of the present utility model, identical with general footwear, not needing to do any electrostatic operation of leading moves again, and can be at any time on one's body with static get rid of, reduce the injury of human body, instrument and improve work safety, and the simple structure of this Static electricity discharging shoes, quite easy in the manufacturing assembly, can reach the purpose that reduces cost.
