Abstract

The utility model discloses a safety shield for a welder, which belongs to the field of welding shields, and is particularly suitable to be used under severe welding conditions. The safety shield comprises a head cap which can be worn on the head of the welder, wherein filter lenses are arranged at positions in front of the head cap corresponding to human eyes; air filters are arranged at positions on the head cap corresponding to the positions of the mouth and noses of a person; a micro air conditioner is arranged on the back part of the head cap; and a dust-proof cover for preventing dust from entering which is connected with the head cap is arranged beneath the head cap. Compared with a welding helmet, the safety shield for the welder has the advantages that the welder can be protected from light pollution, pollution of welding gases and filed dust and hurt caused by unexpected attacks.

Description

The welder uses safty shield

Technical field

This utility model relates to a kind of welder and uses safty shield, belongs to welding protective cover field.Be particularly suitable for using under the abominable welding condition of environment.

Background technology

During welder's operation, not only can produce strong ultraviolet and pollute, also produce a large amount of toxic and harmfuls, can have a strong impact on the healthy of Welder.Simultaneously, have no time to attend to other during due to Welder's operation, the strike that often will have an accident, these all make the Welder become high-risk occupation.On general practical protective mast, a transparent position is arranged at present, transparent position is high-performance sunglasses, and purpose is to prevent that the high light that welds from injuring Welder's eyes.Its weak point is the radiation that can not prevent ultraviolet radiation and gas, and the injury that can not prevent from having an accident and cause when hitting.

Summary of the invention

For addressing the above problem, this utility model provides a kind of welder to use safty shield.

This utility model is realized with following technical scheme: a kind of welder uses safty shield, it comprises the head-shield that can be worn over Welder's head, at the corresponding people's in the front of head-shield eyes position, filter lens is arranged, nose and mouth the corresponding people of head-shield are equipped with air filter, mini air conditioner is equipped with at rear portion at head-shield, and the dust cover that dust enters that prevents with its connection is arranged below head-shield.

Filter lens not only can shading but also the ultraviolet that welding produces can be filtered out, and exempts to hinder operator's eyes.After air filter filters, make air become cleaning, totally, safety.Mini air conditioner is regulated the air in safety guard, and air-conditioner effluxes the air in safety guard when causing in cover negative pressure, and the air of outside just replenishes continuously along filter, makes air cleaner in cover, and helps the interior distribute heat of cover.Dust cover does not advance in cover the dust of job site, makes the operating personnel that a good working environment be arranged.

The beneficial effects of the utility model are: compare with existing welders' mask, can make the workman when not being subjected to light pollution, can not be subjected to the pollution of welding gas and on-the-spot dust, can exempt from the unexpected injury that causes of hitting simultaneously.

In figure: 1, head-shield, 2, filter lens, 3, filter, 4, mini air conditioner, 5, dust cover, 6, safe strap.

The specific embodiment

As depicted in figs. 1 and 2, the welder mainly is comprised of head-shield 1, filter lens 2, air filter 3, mini air conditioner 4, dust cover 5 with safty shield.Filter lens 2 is contained in the corresponding people's in front of head-shield 1 eyes position, and air filter 3 is contained in the corresponding people's of head-shield 1 nose and mouth, and mini air conditioner 4 is contained in the rear portion of head-shield 1, and dust cover 5 prevents that dust from entering below connecting head-shield 1.And embodiment head-shield 1 is to make with fiberglass, as shown in Figure 3, in head-shield above, be provided with and prevent the safe strap 6 that has an accident and hit.Safe strap 6 is that the requirement according to safety helmet arranges strap, and when using, the crown and safe crown have the distance of 20-30, and its effect is to be unlikely to cause when preventing from having an accident strike cerebral concussion can also play the effect of human-body radiating.

Filter lens 2 is made by inside and outside two-layer eyeglass, and internal layer is 3 millimeters thick light transmission glass plates, and skin is filter glass.3 millimeters thick light transmission glass plates are fixed on head-shield 1, and the filter glass Telescopic movable is arranged on head-shield 1.Filter glass can filter out the ultraviolet that welding produces, and exempts to hinder operator's eyes.During use, first outer filter lens is opened, do not affected like this operating personnel's vision, when preparing welding, outer filter is put on ultraviolet ray filtering.Hinged between outer optical filtering picture frame and inner layer metal frame, outer filter lens can be easy to open and close.

Air filter 3 is filters of canister respirator, is arranged on the correspondence position of operating personnel's mouth and nose, enters the air in safety guard, after filtering through filter, and the cleaning that just becomes, clean, safety.

The effect of mini air conditioner 4 is air of regulating in safety guard, and air-conditioner effluxes the air in safety guard when causing in cover negative pressure, and the air of outside just replenishes continuously along filter, makes air cleaner in cover, and helps the interior distribute heat of cover.

Dust cover 5 use canvas or Corii Bovis seu Bubali are made, and the dust of job site is not advanced in cover, make the operating personnel that a good working environment be arranged.

Using method is: before welder's operation, be with safty shield, open mini air conditioner, make the protective cover sealing, open filter lens.After operation is ready, be with filter lens before welding, can carry out weld job.

Weld and open filter lens after complete, unload safety guard, close air-conditioning.
