Abstract

The utility model relates to a head welding mask suitable for the occasions of arc guidance, weld, etc., which mainly comprises a mask shell, a head band and a turning cover. The structure is characterized in that a ventilation window frame and a ventilation window are designed. The ventilation window frame is fixed with the mask shell and is connected with the hinge of the turning cover. The ventilation window is arranged on the ventilation window frame. Thus the utility model has the advantages of reasonable structural design, good observing clearness of the weldment, good ventilation performance, simple design, low cost, etc.

Description

Headgear type electric welding mask

This utility model relates to a kind of face shield, particularly a kind of headgear type electric welding mask, and it mainly is applicable to striking, welding occasion.

Electric welder's helmet mostly is hand-held in the prior art, its structure as shown in Figure 1, it mainly by handle 1 ', case 2 ', screening glass 3 ' and protection eyeglass 4 ' form, the electric welder's helmet of this structure remains in actual use in following shortcoming: 1, structural design is reasonable inadequately, need grasp handle during use, convenient inadequately; 2, after the operation, need whole face shield taken down and could observe weldment, otherwise can not the clear view weldment, so, face shield is taken up and down extremely loaded down with trivial details.Although, headgear type electric welding mask is also arranged at present, whole design is comparatively complicated, owing to be provided with interior screening glass more, so, can not clearly observe owing to operator's breathing when observing weldment, simultaneously, the operator also feels unhappy and facial being heated deeply and exaggerates.

The purpose of this utility model is the deficiency that overcomes all existence in the prior art, and a kind of reasonable in design, easy to use and reliable, the high headgear type electric welding mask of operation definition are provided.

The purpose that the utility model proposes can be achieved through the following technical solutions; This electric welder's helmet comprises case, head hoop and renovates, and renovates screening glass and outer screening glass are installed, and its construction features is also to be provided with ventilative window frame and ventilative window, and ventilative window frame is fixed with case, and is connected with renovating, and the window of breathing freely is then opened on the window frame of breathing freely.

The purpose that the utility model proposes can also be come further perfect by the following technical programs: be provided with location-plate in addition, have locating hole on the location-plate, this locating hole is complementary with the alignment pin that is located on the case.

Description of drawings is as follows:

Fig. 1 is the structural representation of electric welder's helmet in the prior art.

Fig. 2 is a structural representation of the present utility model.

Following this utility model will be in conjunction with the accompanying drawings, and be described in further detail by embodiment

Referring to Fig. 2, this utility model mainly by case 1, head hoop 6, ventilative window frame 12, ventilative window 13, renovate 5, outer screening glass 3 and screening glass 4 form, be connected by screw bolt and nut 8 between case 1 and the head hoop 6, and head hoop 6 is provided with conciliation knob 7; Ventilative window frame 12 designs are in the front of case 1, and fixing with case 1, have ventilative window 13 on the ventilative window frame 12, be convenient to renovate 5 and open the ventilative usefulness in back, ventilative simultaneously window frame 12 also with renovate 5 hinges and be connected; Renovate screening glass 4 and outer screening glass 3 are installed on 5, in order to the protection eyes, then in order to protection screening glass 4, outer screening glass 3 is made by outer screening glass 3 usefulness fire proofings when work for screening glass 4, and screening glass 4 useable glass are made.In addition, also design has a location-plate 10, and this location-plate 10 is fixed together with head hoop 6 and case 1, has locating hole 9 on the location-plate 10, and case 1 is provided with alignment pin 11, and alignment pin 11 is complementary with locating hole 9, is used to regulate the last lower angle of case 1.Certainly, adjusting of lower angle also can realize with gear structure on this.

Before the welding, can renovate 5, renovate 5 and just change 90 degree down immediately to pressing down, with ventilative window frame heavy and, just can carry out striking, welding thus; After the welding, upwards push away as long as will renovate 5, change last 90 degree immediately just renovate 5, the operator just can clearly observe weldment by ventilative window frame 12 thus.

The utility model compared with prior art has following advantage: 1. Reasonable in design is because design Ventilative window frame and ventilative window are arranged, make the operator after welding, can more clearly observe weldment, be convenient to simultaneously breathe freely, Avoided the generation of the phenomenon such as unhappy; 2. Simplicity of design, reasonable, cost is low, good economy performance.
