Description

Join the hat type electric welder's helmet

Technical field

The protection apparatus that uses when this utility model relates to welding operation, specifically a kind of welding mask.

Background technology

The protective mast that uses during welding at present is usually by following three kinds: 1, hand-held, 2, wear-type, 3, join hat type.The appearance of joining the hat type protective mast has solved to wear a safety helmet does not just wear the difficult situation of protective mast, general large-scale shipyard, and machinery plant, that uses on the engineering is many.

The existing hat type protective mast of joining normally is hinged on the air vent of safety helmet both sides, and face shield can upwards be raised on safety helmet or put down downwards.In welding operation, the frequency that face shield is raised or put down is higher as required, existingly join the deficiency that the hat type protective mast exists and be: 1, between face shield and safety helmet during hinged tension, can be with when lifting face shield up and down safety helmet one starting even or safety helmet is come off, when hinged mistake is loose between face shield and safety helmet, the face shield raised can be uncontrolled and oneself falls down, and then influence work efficiency; 2, the installation on safety helmet and dismounting are inconvenient, and the safety helmet both sides that have do not have air vent, for equipped protective mast, need be at safety helmet two side perforatings, and this can reduce the safety of safety helmet; 3, structure is complicated, weight is bigger, wears more uncomfortable for a long time.

The utility model content

The purpose of this utility model is to provide a kind of hat type electric welder's helmet of joining, and this electric welder's helmet can conveniently be installed and removed at safety helmet, and can conveniently on safety helmet raise or put down as required.

For achieving the above object, this utility model adopts following scheme: be fitted to the electric welder's helmet on the safety helmet, it has a face shield, the middle part of face shield has observation window, the top of face shield is connected with deck, has chute on the deck, has passed fixing band in the chute, deck and fixing band are provided with the locking mechanism that both are interfixed, and that the bending of the front end of fixing band is is hook-shaped, the rear end is connected with elasticity and articulates member.

By such scheme as seen, the front end of fixing band is caught on the brim of a hat of safety helmet front portion, the edge, rear portion that elasticity is articulated member rear end and safety helmet articulates, and this electric welder's helmet can be installed on the safety helmet.When the mobile face shield of needs, open the locking mechanism between deck and fixing band, face shield can be moved along fixing band together with deck, and then realize raising or putting down of face shield; With the front end of fixing band and articulate the member rear end and separate with safety helmet, can pull down this electric welder's helmet easily.

This utility model is rational in infrastructure, easy to use, and it can be installed and removed at safety helmet quickly and easily, and face shield conveniently moving, flexibly in use, is a kind of desirable electric welder's helmet that can be equipped with safety helmet.

Description of drawings

The structural representation of Fig. 1 this utility model one embodiment;

The A-A cutaway view of Fig. 2 Fig. 1;

The B portion enlarged drawing of Fig. 3 Fig. 2;

Fig. 4 user mode sketch map of the present utility model.

The specific embodiment

Further specify this utility model below in conjunction with embodiment and accompanying drawing.

Referring to Fig. 1, Fig. 2

The middle part of the face shield 6 that the electric welder's helmet that this utility model provides has has observation window 8, and the top of face shield 6 is connected with deck 5, has chute 5c on the deck 5, has passed fixing band 3 among the chute 5c, and the front end bending of fixing band 3 is hook-shaped.The elasticity that the rear end of fixing band 3 is connected with articulates member and has spring 2 and hook 1, and the two ends of spring 2 are connected with fixing band 3 with hook 1 respectively, and it is a pair of that elasticity articulates member.

In the present embodiment, deck 5 is connected as a single entity by bearing 5b and a pair of slide block 5a and constitutes, and bearing 5b connects with the top of face shield 6, and the inboard of two slide block 5a has chute 5c, and fixing band 3 passes the chute 5c on the two slide block 5a.Be hinged with movable window 7 in the outside of observation window 8.Colour of lens on the movable window 7 is dark, and colour of lens is light color on the observation window 8, when welding operation, movable window 7 is put down, and when welding intermittently maybe need be observed the welding situation, movable window 7 can be started.In addition, if the eyeglass on the observation window 8 adopts the automatic beam change eyeglass, then movable window 7 can be removed.

Referring to Fig. 1, Fig. 2, Fig. 3

Deck and fixing band are provided with the locking mechanism that both are interfixed and are made of with the some double wedge 3b that are distributed on fixing band 3 upper sides a claw 4, claw 4 is 5a between two slide blocks, the part of claw 4 both sides is connected as a single entity with a slide block 5a respectively, the front end of claw 4 has the hook 4a of bending, and hook 4a is meshed with double wedge 3b.

Referring to Fig. 2, Fig. 4

At the downside of fixing band 3 back-up block 3a more than two is arranged fixedly.After fixing band 3 is installed on the safety helmet 9, back-up block 3a and safety helmet 9 against, make 9 of fixing band 3 and safety helmets maintain the space, be not obstructed when fixing band slides to guarantee two slide block 5a.

In conjunction with Fig. 1, Fig. 2, Fig. 3 and Fig. 4 as seen, the front end of fixing band 3 is caught on the brim of a hat of safety helmet 9 front portions, the edge, rear portion of hook 1 with safety helmet 9 articulated, this electric welder's helmet can be installed on the safety helmet 9.When the mobile face shield 6 of needs, pin claw 4, after claw 4 was given birth to strains, the hook 4a of its front end separated with double wedge 3b on the fixing band, face shield 6 can be slided along fixing band 3 together with deck 5, and then realize raising or putting down of face shield 6; Unclamp claw 4, after its distortion recovers, hook 4a and fixing band upper raised teeth 3b engagement, face shield 6 can be fixed.With the front end of fixing band 3 and link up with 1 and separate with safety helmet, can pull down this electric welder's helmet easily.

In addition as seen from Figure 4, since fixing band 3 be in safety helmet 9 directly over, increased the safety of safety helmet virtually again, in face of the workman slides onto face shield 6 when welding operation, many fixing bands 3 directly over the safety helmet 9, if the top object then touches fixing band earlier when falling to safety helmet, safety helmet has been played a cushioning effect; If in welding operation intermittently, face shield 6 is slid onto just going up of safety helmet 9, then there is two buffer layer the top of safety helmet.
