Abstract

The utility model relates to a chin controlled eye protection mask which comprises a helmet type mask. The utility model is characterized in that the front side of the mask is in an interlayer type, and corresponding viewing windows corresponding to the positions of eyes are arranged on two interlayer walls. Flat light glass is arranged on an external viewing window, and a filter glass which can move up and down is arranged in the interlayer corresponding to the internal and the external viewing windows. Both sides of the filter glass are respectively fixed with a guide rod on which a return spring is arranged. Sliding holes which can be inserted with the guide rods are arranged at outer walls above and below both sides of the viewing windows. The guide rod is connected with a linking frame which is extended to the inner lower part of the mask from both sides of the internal viewing window and can support the chin. The chin controlled eye protection mask has the advantages of simple structure, low cost, convenient operation, high work efficiency, safety and reliability.

Description

Chin control safety visor

This utility model relates to the face shield that a kind of electric welding is used, and particularly is applicable to the chin control safety visor that uses when vertical position welding, spot welding, overhead welding etc. are welded.

Welding worker all is a hand steered workpiece when welding; one hand-held soldering turret; have on faceplate on the head; and the filter glass on the at present used faceplate is fixed on the viewing window; so be worn on the head in the time of can only being welding; protect eyes with face shield; short time stops weldering and changes welding rod, strikes slag, checks that face shield is raised or taken off to handy hands, wears during welding when welding condition again; when especially carrying out spot welding; handy hand steered a face shield constantly moves with welding, accidentally will be by welding flash eyes and skin of face; dangerous, inconvenience.

Existing China Patent No. is 93220620.4 " light-operated electric curtain formula light valve protective eye lens ", though it can automatic beam change, and the production cost height, price is expensive, also generally promotes at present.

Task of the present utility model provides a kind of simple in structure, and is with low cost, and control is convenient, chin control safety visor safe in utilization.

Task of the present utility model is finished like this, it includes a helmet-type face mask, it is characterized in that: the front of face shield is interlayer, corresponding eyes place has corresponding viewing window respectively on the two interlayer walls, zero diopter glass is arranged on the outer viewing window, there is a filter glass moving up and down inside and outside viewing window corresponding position in the interlayer, the filter glass both sides are fixed with guide rod, back-moving spring is arranged on the guide rod, the outer wall of viewing window both sides upper and lower is provided with the slide opening that can insert guide rod, be connected with one on the guide rod and extend to the interlock frame that chin can be held in bottom in the face shield from interior viewing window both sides, in order to be convenient to observe than long time stopping the weldering time, below filter glass, be connected with a pull bar that leads to OFP subordinate side, the card ball is arranged on the pull bar, have on the face shield with the card ball to cooperate the dislocation hole clipping that to block the card ball or unclamp the card ball, filter glass can be left behind and be stuck on the bigger aperture position, the face shield and the helmet are connected and fixed with axle and nut, and vertical angle can be regulated with interior at 25 degree by adjusting knob.

This safety visor moves down because of utilizing opening of chin to drive filter glass, makes viewing window go out to expose a light penetrating slit, and sight line can be observed the outside from here easily, and is easy to operate, improves work efficiency, guarantees safety.Be particularly suitable for China's national situation, simple in structure, reliable operation, the suitable popularization.

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is a backsight part section structural representation of the present utility model;

Fig. 2 is a side-looking structural representation of the present utility model;

This utility model utilizes a helmet-type face mask to improve and forms, and the preceding bottom of the helmet 1 connects with axle with face shield 2 tops, and nut is fixed, and can regulate with interior at 25 degree, to adapt to the head dummy of different sizes.The front of face shield is screwed an interlayer, be provided with inside and outside viewing window respectively corresponding to the eyes place, insertable zero diopter glass is housed on the outer viewing window, a filter glass 4 moving up and down is arranged between the inside and outside viewing window, filter glass 4 both sides are fixed with a guide rod 6 respectively, back-moving spring 5 is housed on the

guide rod

6,3 li of the slide openings that are fixed on the outer inwall of face shield are inserted at two up and down of guide rod 6 respectively, are connected with one on the guide rod 6 and extend to the interlock frame 9 that chin can be held in bottoms in the face shield 2 from interior viewing window both sides.In order to observe more convenient than long time stopping the weldering time, be fixedly connected one in filter glass 4 bottoms and lead to the face shield 2 bottoms pull bar 7 outstanding from the inclined-plane of interlayer outer wall, there is the card ball to match on the pull bar 7, filter glass 4 is moved down on the position of viewing window aperture maximum with the dislocation hole clipping at outstanding position, face shield bottom.When interlock frame 9 drive filter glasss 4 were moved up and down in less aperture scope, the card ball on the pull bar 7 can not expose outside the face shield 2, therefore can not influence its operation yet.
