Abstract
The utility model provides a light controlling and shading shield for a welder to protect the eyes and the face of the welder, comprising a face mask and a safety cap. The light controlling and shading shield for a welder is characterized in that the face mask is provided with a shading eyeglass frame which is composed of an optical control circuit and a lifting mechanism for deep color eyeglass. When arc light irradiates onto a photoresistor above the face mask, a light controlled circuit is put through; the shading eyeglass is lifted quickly by a transmission mechanism to protect the eyes. When welding is stopped, the deep color eyeglass falls quickly and a piece of eyeglass made of transparent glass is exposed, so an operator can observe the situation of a welded object conveniently.
Description
The light-operated sunscreen protection device of electric welding is a kind of welding worker shading protection eyes and facial safety device, belongs to labor protection utensil technical field.
At present the electric welder's helmet that uses of welder mostly is hand-held, and the helmet-type face mask that is used with safety helmet and need not hands is also arranged.But common defects is: shading is protected the deep-color lens that order uses and is fixedly mounted on face shield, in case stop weldering need watch the welding situation time, will remove face shield, influence work efficiency, also causes operation inconvenient.
The purpose of this utility model just provides a kind of need not handing, can make again deep-color lens along with the electric welding operation the automatic sunscreen protection device of lifting.It comprises face shield and safety helmet.
Fig. 1 is the light-operated preventer structural representation of electric welding.
Fig. 2 is the structural representation of framework (4).
Fig. 3 is light-operated circuit figure.
Framework (3), framework (4) are equipped with respectively in the two sides, front and back of face shield (1), framework (3) has socket and inserts clear glass eyeglass (2), framework (4) is equipped with the elevating mechanism of a light-operated circuit and deep-color lens, on the axle of micro motor (6) change-speed gearing (7) is housed in the light-operated circuit (5), gear (8) setting-in screw rod (9), the slip nut (11) that screw rod (9) top suit is connected with sunshade lens inner frame (18); The both sides of framework (4) have chute (12); Sunshade lens (10) just in time overlaps with clear glass eyeglass (2) when the tip position of framework (4); Photo resistance in the light-operated circuit (17) is installed in the top of face shield (1).
Face shield (1) is connected by movable button (16) with safety helmet (15), and face shield can upwards turn over and put.
Be furnished with wind on the safety helmet (15) and transfer machine mouth (13), can to improve working conditions, also be furnished with the lamp jack of working at night (14) with in the outside wind regime access cap, in Power Supplies Condition at one's leisure, external direct current power supply or low-tension supply are used.
K switch B adopts the radio cassette player playback switch in the circuit diagram, and FC52 is the operational amplifier integrated circuit, N
1Be reversible electric machine, KC is supply socket.
Operation principle is like this: when quiet shape does not have the electric arc welding light source, and the adhesive of light-operated circuit relay J, contact 1,2 is connected, and makes light emitting diode D
2Light the miniature reversible motor M
1Do not work.When the arc light irradiation was arranged when electric welding, light-operated circuit relay J releasing contact 3,4 was connected, and made 9 volts of power supplys insert micro machine M by K switch B
1, driven gear (8,9), screw rod (10) rotation drive sliding frame (18) and upwards slide rapidly.After sliding frame put in place, impact switch KB driving lever cut off micro-motor power supply, and micro machine quits work.Dark glass overlaps with clear glass, with the protection eyes.When not electric welding, because the irradiation of no arc light, photoconductive resistance (17) resistance increases, and light-operated circuit repeat circuit J adhesive contact 1,2 is connected, and makes power supply pass through K switch B, oppositely inserts micro machine M
1, the motor counter-rotating, the dark mirror in the drive sliding frame is rapidly to lower slider, and eyes can be observed the welding situation by clear glass.After sliding frame put in place, the driving lever of impact switch KB was got back to original position, cut off motor power and quit work.
This utility model uses through reality, and working stability is reliable, cost is low, easy popularization.
Claims (3)
1, a kind of welding worker shading protection eyes and facial light-operated sunscreen protection device of electric welding of being used for, comprise face shield, safety helmet, it is characterized in that face shield (1) is last except that the framework (3) that clear glass eyeglass (2) have been installed is housed, a shading lens frame (4) of being made up of light-operated circuit and deep-color lens elevating mechanism also is equipped with at its back side; On the axle of micromotor (6) change-speed gearing (7) is housed in the light-operated circuit (5), gear (8) setting-in screw rod (9), the slip nut (11) that screw rod (9) top suit is connected with shading eyeglass (10), the both sides of framework (4) have chute (12); Shading eyeglass (10) just in time overlaps with clear glass eyeglass (2) when the tip position of framework (4); Photoconductive resistance (17) is equipped with on the top of face shield (1).
2, the light-operated sunscreen protection device of electric welding according to claim 1, its feature are that also face shield (1) is connected by movable button (16) with safety helmet (15).
3, the light-operated sunscreen protection device of electric welding according to claim 1, its feature also are to be furnished with on the safety helmet (15) wind and transfer machine mouth (13) lamp jack (14) of working at night.
