Description

The safety helmet electric welder's helmet

Technical field

This utility model relates to electric welder's helmet, specifically a kind of electric welder's helmet be worn on safety helmet.

Background technology

Existing safety helmet electric welder's helmet normally is hinged on the air vent of safety helmet both sides, and face shield can upwards be raised or put down downwards on safety helmet.In welding operation, the frequency of as required face shield being raised or being put down is higher, existingly join the deficiency that the hat type protective mast exists and be: 1, upper turn over to pack up with rear mask on safety helmet, can upwarp, if wind is being arranged or can increase the weight of head weight in walking; 2, structure is more complicated, weight is larger, wears for a long time more uncomfortable.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of safety helmet electric welder's helmet of simple in structure, easy to use, comfortable wearing.

For achieving the above object, this utility model adopts following scheme: the safety helmet electric welder's helmet, it has a face shield, the middle part of face shield has observation window, the face shield both sides are respectively arranged with the first dwang and the second dwang, the front end of the front end of the first dwang and the second dwang is hinged with face shield top one side respectively, and the rear end of the rear end of the first dwang and the second dwang is hinged with an end of framework respectively; Described framework is approximate " U " type, and fluted on the framework medial wall, the trend of groove is consistent with the trend of framework, and the framework two ends are connected with elastic component.

Visible by such scheme, the radian of the identical helmet brim of the radian of U-shaped frame front, agree with the brim of a hat of the groove of framework inboard and safety helmet, and the elastic component that coordinates the framework two ends to connect, can be fixed on safety helmet originally joining the cap-type electric-welding face shield; Because face shield is connected on framework by the first dwang and the second dwang, and between the first dwang and the second dwang front and back end and face shield and framework, be hinged, therefore can guarantee to turn on each face shield and pack up Shi Douhui laminating safety helmet surface, produce and rock above safety helmet to alleviate face shield.

This utility model is simple and reasonable for structure, and it installs and removes convenient on safety helmet, and the sense of discomfort while wearing is lighter.

For clearer explanation technology contents of the present utility model, below by safety cap electric welder's helmet referred to as this electric welder's helmet.

In this electric welder's helmet, the elastic component that the framework two ends connect is spring.

The framework of this electric welder's helmet and the first dwang rear end are hinged by the first bearing pin, framework and the second dwang rear end are hinged by the second bearing pin, face shield top is fixed with support bar, face shield top is fixed with support bar, one end of the front end of the first dwang and support bar is hinged by the 3rd bearing pin, the front end of the second dwang and the other end of support bar are hinged by the 4th bearing pin, on the 3rd bearing pin, on the 4th bearing pin, torsion spring is housed respectively, the two ends of the torsion spring on the 3rd bearing pin respectively with the first dwang and face shield against, the two ends of the torsion spring on the 4th bearing pin respectively with the second dwang and face shield against.After adopting such structure, the convenient face shield rotational angle of controlling.

This electric welder's helmet is hinged with active window in the outside of observation window; After adopting such structure, the colour of lens on active window can be selected dark color, and on observation window, colour of lens can be selected light color, when welding operation, active window is put down, select flexibly the using state of active window, and do not affect normal use, increase the scope of application of this electric welder's helmet.

The specific embodiment

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4

The fluted 1a in the inboard of U-shaped framework 1, the trend of groove 1a is consistent with the trend of framework 1, and the elastic component that framework 1 two ends connect is a spring 2.

Face shield 5 is the arc face shield of approximate human face's profile, the middle part of face shield 5 has observation window 5b, is hinged with active window 5c in the outside of observation window 5b, and the colour of lens on active window 5c is dark, the upper colour of lens of observation window 5b is light color, when welding operation, active window 5c is put down, when welding intermittently maybe needs to observe the welding situation, active window 5c can be started, in addition, if the eyeglass on observation window 5b adopts the automatic beam change eyeglass, active window 5c can be removed.

Framework 1 both ends are hinged with respectively the first dwang 3a and the second dwang 3b, the structure of the first dwang 3a and the second dwang 3b and measure-alike, framework 1 and the first dwang 3a rear end are hinged by the first bearing pin 4a, framework 1 and the second dwang 3b rear end are hinged by the second bearing pin 4b, the centrage of the centrage of the first bearing pin 4a and the second bearing pin 4b, is first axle M point-blank.

Face shield 5 tops are fixed with support bar 5a by screw, and the radian of the degree of crook of support bar 5a and face shield 5 matches; The end of the front end of the first dwang 3a and support bar 5a is hinged by the 3rd bearing pin 4c, the other end of the front end of the second dwang 3b and support bar 5a is hinged by the 4th bearing pin 4d, the 3rd bearing pin 4c is upper, torsion spring 7 is housed respectively on the 4th bearing pin 4d, the two ends of the torsion spring 7 on the 3rd bearing pin 4c respectively with the first dwang 3a and face shield 5 against, the two ends of the torsion spring 7 on the 4th bearing pin 4d respectively with the second dwang 3b and face shield 5 against.The centrage of the centrage of the 3rd bearing pin 4c and the 4th bearing pin 4d, is the second axis N point-blank.

Referring to Fig. 1, Fig. 2, Fig. 5

During use, the groove 1a in framework 1 coordinates with the brim of a hat 6a of safety helmet 6 front portions, and the spring 2 at connecting frame 1 two ends is walked around to safety helmet 6 rear ends, will between this electric welder's helmet and safety helmet 6, fix by self elastic force of spring 2.

When the operator needs weld job, regulate the first dwang 3a and the second dwang 3b along first axle M rotation, make face shield 5 be in safety helmet 6 front sides, then regulate face shield 5 and rotate along the second axis N, and block operator's face fully;

In the intervals of business or special circumstances need to pack up face shield 5 time, regulate the first dwang 3a and the second dwang 3b rotates along first axle M, make face shield 5 be in safety helmet 6 upsides, do not block operator's sight line, regulate face shield 5 again and rotate along the second axis N, guarantee to turn over while packing up face shield 5 safety helmet 6 surfaces of all can fitting on each face shield 5, concora crush gets off and can not upwarp, to alleviate face shield 5, produce and rock above safety helmet 6, make this electric welder's helmet stressed more reasonable on safety helmet 6.

In addition as seen from Figure 3, due to this electric welder's helmet, be in the upside of safety helmet 6, virtually increased again the safety of safety helmet 6, if when the top object falls to safety helmet 6, first touch this electric welder's helmet, safety helmet 6 has been played to a cushioning effect.

Above-described is only a kind of embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from this utility model principle; can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
