Abstract
The utility model discloses a protective cover for welding on which a visual hole and a head band are arranged. Screening glasses are hinged on the external cover of the visual hole. The open and close of the glasses are controlled by a linkage mechanism, which is arranged on the internal side of the cover. An elastic clip, which can be put into the mouth, is arranged on the linkage mechanism. The open and close of the elastic clip makes the glasses turn around with the glass pillar. The protective cover can be easily put on head. The open and close of the screening glasses, relevant to the visual hole, is controlled by the linkage mechanism. Thereby the operator does not need to hold the protective cover with hands and can work with two hands, thus improving work efficiency and enabling the operator to observe the components at will without harming the eyes.
Description
Technical field
This utility model relates to a kind of keeping device, is the welding protective cover that the welder uses when work specifically.
Background technology
Existing welding protective cover, generally be divided into hand-held and wear-type, the hand-held welding needs to hold operation with hands with protective cover in use, when weld job, take electrode holder on the other hand, take the welding protective cover on the other hand, trouble very, particularly when two separating objects of welding, both hands can not co-ordination, often need people from next door to help and just can finish welding, this is particularly inconvenience when work high above the ground or narrow and small local work.Though wear-type welding has economized out a hands with protective cover, at the accurate workpiece of welding and need frequently, protective cover need frequently be removed, inefficiency, and may so the burn eyes or the facial skin of burning with observing when examining workpiece.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of operator neither to be needed to hand, and can observe workpiece at any time again, and eyes is difficult for coming to harm, the wear-type welding protective cover of high efficiency.
For solving the problems of the technologies described above, this utility model comprises face shield, be provided with eyesight and head hoop on face shield, its construction features is to be hinged with screening glass on the face shield in the eyesight outside, and screening glass is controlled by the linkage that is located at the face shield inboard with respect to the folding of eyesight.
Described linkage comprises the eyeglass pillar that is supported on the face shield, and described screening glass is provided with picture frame, and the end hinge of picture frame is contained on the eyeglass pillar; On the face shield of two eyesight middle lower portion, be provided with chute, be provided with slide in the chute, on picture frame, be hinged with the vertical connecting rod of stretching down near the pillar outside, the both ends of one arc connecting rod are connected with the vertical connecting rod end respectively, be provided with the backguy of passing slide from the middle part of arc connecting rod, in the backguy between arc connecting rod and the slide, be provided with spring, in the backguy below the slide, be set with guide pin bushing, be provided with the elasticity folder that can put into mouth in the backguy of guide pin bushing lower end, the folding drive screening glass that is pressed from both sides by elasticity rotates around the eyeglass pillar.
The protection picture frame protects picture frame outward and is provided with outer protection glass outside the outside of screening glass is provided with.
Be provided with the face shield bracing frame in the left and right sides of face shield, described head hoop is installed on this face shield bracing frame.
After adopting said structure, this welding can be worn on the head easily with protective cover, because screening glass is controlled by the linkage that is located at the face shield inboard with respect to the folding of eyesight, can be during operation as required by the folding of this linkage control screening glass, the operator neither needs hand-held this protective cover, can carry out work by both hands, increase work efficiency, can observe workpiece at any time again, and eyes are difficult for coming to harm, flexible operation, convenience.Linkage is by the elasticity folder action that can put into mouth, and operation freely.Protection glass outside the protection picture frame reaches outside the outside of screening glass is provided with had both protected screening glass to be difficult for sustaining damage, and can further protect eyes not come to harm again.
