Pond.The electric welder's helmet of the invention patent can be directly sleeved on head, and thorough liberation both hands improve work efficiency, work and
Carry it is all very convenient, while darkening screen can automatic beam change protect eyes, play the role of labour protection.
But the automatic beam change screen electric welder's helmet of this wear-type is generally more thick and heavy, is engaged in the operator of welding
Long periods of wear can aggravate the burden of cervical vertebra, cause the fatigue of musculi colli group, cause nerve, blood vessel and marrow around cervical vertebra by
, to generate cervical vertebra disease symptoms, there is neck-shoulder pain, upper limb and the numbness of fingers, dizziness, headache, shoulder arm muscular atrophy etc. in pressure
Phenomena such as symptom, serious person leads to neck osteoproliferation, induces the lesions such as intervertebral disc degradation, stenosis of disc space, for long-term
It is engaged in for the worker of electric welding field, threatens health and safety.
Summary of the invention
The purpose of this utility model is in view of the above problems, providing one kind not only can be convenient use, but also can reduce to neck
The wear-type automatic light-changing electric-welding face guard of vertebra compressing.
The technical solution of the utility model is: a kind of wear-type automatic light-changing electric-welding face guard having shoulder support arm, including
Mask body and its attached headband, automatic beam change observation window and spiracle, it is characterized in that: being set respectively at left and right sides of mask body
It is equipped with the shoulder support arm of two shoulders of corresponding left and right.
The shoulder support arm is made of support shank, half-moon-shaped structure and elastic reducing-fixing band, wherein the upper end of support shank
It is connected with mask body using screw thread, support shank lower end is provided with half-moon-shaped structure, is arranged at half-moon-shaped structure both ends flexible
Fixing belt.
The elastic reducing-fixing band is the resilientiy stretchable structure for being suitable for shoulder of different sizes and wearing, and can be pine
Taut band, rubber band are also possible to other flexible scalability materials.
The headband has the slidably rack gear of length adjustable；Sponge or activity are provided on the inside of the spiracle
Charcoal or similar filtering material.
The automatic beam change observation window top is divided into photoreceptor, and lower part is divided into darkening screen, after photoreceptor and darkening screen
Side is provided with control chip, and the photoreceptor and darkening screen include the external protection, liquid crystal layer, purplish red that ecto-entad is bonded to each other
Absorbed layer and inner protective layer composition, the liquid crystal layer includes several liquid crystal light valves, each liquid crystal light valve respectively corresponds company
A light valve drive circuit is connect, several light valve drive circuit serial or parallel connections, and connect respectively with control circuit board, the control
Circuit board processed connects a power supply circuit, and the power supply circuit connects battery.
The utility model takes above technical scheme, has the advantages that.
1, hand shield is not needed when welding, has liberated both hands, operation is very easy, and then improves work efficiency and pacify
Quan Xing especially meets the particular surroundings need of work such as high altitude operation, mine, hillside.
2, since the shoulder support handle being connected with mask acts on shoulder, part mask weight has been shared by trunk, has been subtracted
Light compressing of the electric welder's helmet to cervical vertebra can effectively reduce and wear mask for a long time and generate cervical vertebra class disease, play good labour
Protective effect.
3, when welding operation, light valve drive circuit, which plays a role, controls darkening screen automatic beam change to protect eyes, and welding stops
Only, darkening screen restores transparent, and welding personnel is facilitated to observe, easily and effectively to the protections of eyes.
