Abstract
The utility model relates to a self-peeping electrical welding mask. A peephole (13) is arranged on the mask (1), a light filtering lens (6) which can rotate around a moving pin (10) is arranged on the mask at the outer side of the peephole, and one end of a return spring (12) is connected to the light filtering lens (6); the other end is connected to the mask, and simultaneously a control switch (9) for controlling the rotation, the opening and the closing is also arranged on the light filtering lens (6). The electrical welding mask can automatically control the opening and the closing of the mask light filtering lens through the opening and the closing of a mouth of a human body and has the advantages of skillful structure and simple operation; the utility model can make a welder vacate a hand to adjust a workpiece, enhances work efficiency and does great good to ensure welding quality without increasing the cost of the mask.
Description
This utility model relates to solder technology, and is particularly a kind of from spying on electric welder's helmet.
Traditional welding mask all has one handle.Welder's left hand is held face shield, and the right hand is held welding gun, and workpiece is welded.When needs are adjusted welded part, must put down welding gun or face shield in the hands, make that so just construction is discontinuous, work efficiency is not high, inconvenience, face or eyes also can be burnt by welding arc sometimes.A kind of wear-type welding mask is arranged,,, when not welding, cannot see workpiece, we can say the also inreal disadvantage that solves aforementioned existing welding mask because sight line is blocked by filter lens though can overcome the defect of aforementioned hand-held face shield.
The purpose of this utility model is: what switching that a kind of opening and closing that utilize the human body mouth control the welding mask filter lens was provided spies on electric welder's helmet certainly, overcomes the deficiency of aforementioned conventional welding mask.
Described electric welder's helmet comprises cover, overskirt, mirror limit, picture frame, each parts of filter lens, it is characterized in that: on the cover (1) of described electric welder's helmet, have a peephole (13), being equipped with one on the outside cover of peephole can be around the filter lens (6) of removable pin (10) rotation, be contained in one of return spring (12) on the removable pin and terminate on the filter lens, the other end then is connected on the cover; The gauge tap (9) of its rotation of one control, folding also is housed on the filter lens (6) simultaneously.
One mirror eyebrow (8) is arranged on the described filter lens (6), and filter lens and mirror eyebrow are " Γ " shape each other; Gauge tap (9) is a control lever, also can be a control rope, and the one end is contained on the mirror eyebrow, and the other end extends to place, human body mouth chin position.
Described removable pin (10) is contained in filter lens (6) and mirror eyebrow (8) intersection, is with key seat (11) on it and return spring (12) is housed.
Through so improving the electric welder's helmet after designing, can control the unlatching and the closure of cover filter lens by the opening and closing of human body mouth automatically, the structure dexterity, easy and simple to handle, can make the welder free hand to adjust workpiece, having improved work efficiency, to guaranteeing that welding quality is of great benefit to and not increasing the face shield cost, therefore is very much practical.
Fig. 1 is this utility model structure principle chart.
Fig. 2 is this utility model structural principle side view.
Fig. 3 uses one of embodiment for this utility model, and the human body mouth closes, view when filter lens is closed.
Fig. 4 uses two of embodiment for this utility model, and the human body mouth opens, view when filter lens is opened.
Among the figure: (1) cover, (2) overskirt, (3) headband, (4) mirror limit, (5) picture frame, (6) filter lens, (7) mirror lining, (8) mirror eyebrow, (9) gauge tap, (10) removable pin, (11) key seat, (12) return spring, (13) peephole.
When the gauge tap that the control filter lens is opened, closed was used the lever transmission control force, lever and fulcrum can be provided with along the face shield inwall, and an end places on the mirror eyebrow, the other end can be enclosed within human body chin position, the small control force that makes the mouth opening and closing is passed on the mirror eyebrow, drives the filter lens open and close.When mouth opens, should make that filter lens opens, expose peephole, make the visible workpiece of welder; When mouth closed, filter lens was taken down, kept off main peephole, can weld.The rope of the also available thickness appropriateness of this gauge tap substitutes, and mechanism is constant.Described electric welder's helmet is as good as with material and traditional face shield, and processing technique is constant, only needs to increase described movable filter lens device and gets final product.The forward and backward two sides of filter lens can respectively be provided with the one side protection and use transmissive mirror, and described face shield is worn on the head, and the end that mouth puts gauge tap can use, and operates very easy.
