Abstract

The utility model discloses a novel electric welding face shield, including a shield casing which is provided with a viewfinder; a liquid crystal eyeglass is mounted in the viewfinder; a handle is connected on the shield casing; the liquid crystal eyeglass is connected with a constantly light/constantly dark mode selection button and a start conversion button through a control module; the controlmodule is connected with a power supply battery; the constantly light/constantly dark mode selection button and the start conversion button are mounted on the handle. The operation of the liquid crystal eyeglass is controlled by the button mounted on the handle, thereby, the operator can set the color to be dark in advance so as to comprehensively protect eyes. There are two modes of constantly light and constantly dark in alternative, thereby the operator can set according to the requirement. The novel electric welding face shield is convenient to use.

Description

Novel electric welder's helmet

Technical field

This utility model relates to a kind of labor protection apparatus, and particularly a kind of electric welding field that is used for carries out the electric welder's helmet of eye protection to the operator.

Background technology

Present hand-held electric welder's helmet generally is that a black lens is installed in form, when operation, the operator in most cases needs to remove face shield with hands earlier, after seeing the position that needs welding clearly, again face shield is retracted and blocked, the shortcoming of its existence is, if the space at place is comparatively narrow, then move operation is very inconvenient, even operate in the place enough in the space, owing in operating process, need to watch and aim at weldering place and constantly remove and retract, trouble not only, and the inaccurate situation of welding position, inefficiency simultaneously appear easily.

In addition; it is on the face shield form liquid crystal lens to be installed that some electric welder's helmets are arranged at present; by sensitization automatic beam change control circuit liquid crystal lens is controlled; after detecting the rays such as ultraviolet that electric arc produces, its light sensor makes the alternating voltage of liquid crystal lens both sides by control circuit; the color of liquid crystal lens becomes dark state by pellucidity; thereby eyes are protected; but; the electric welder's helmet of above-mentioned sensitization control; in any case improve its film speed and control rate; electric arc produces a response time between the liquid crystal lens change color; this response time is always long a lot of to the required time of people's eyes than electric arc light; thereby having light leakage phenomena, the eyes that harm ray still can enter the operator damage it, use reliable inadequately.

Simultaneously, the state of the electric welder's helmet of these band liquid crystal lens all is to become normal black state by normal bright state, without the function imperfection.

Summary of the invention

In order to solve the above problems, the purpose of this utility model be to provide a kind of rational in infrastructure, use reliably, novel electric welder's helmet easily.

The technical scheme that the invention for solving the technical problem adopted is:

Novel electric welder's helmet, comprise case, have form on the case, liquid crystal lens is installed in the form, also be connected with handle on the case, liquid crystal lens is connected with Chang Liang/often black model selection button by control module and conversion starts button, and control module is connected with supplying cell, and Chang Liang/often black model selection button and conversion start button and be installed on the handle.

The beneficial effects of the utility model are: because the work of its liquid crystal lens is controlled by the button that is installed on the handle; the operator can be set to darken in advance; can reach the effect of general protection eyes; need not mobile face shield, swift to operate, flexible, efficient is high, and be provided with Chang Liang and two kinds of transition state patterns of Chang Hei; the operator can set as required; extremely easy to use, effective more a lot of than the protection of automatic beam change, it is simple in structure, durable, economical simultaneously.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the three-dimensional appearance sketch map of this utility model electric welder's helmet;

Fig. 2 is the inside structure sketch map of this utility model electric welder's helmet;

Fig. 3 is the schematic block circuit diagram of this utility model electric welder's helmet.

The specific embodiment

With reference to Fig. 1, Fig. 2 and Fig. 3, novel electric welder's helmet of the present utility model, comprise case 1, have form 2 on the case 1, liquid crystal lens 3 is installed in the form 2, also is connected with handle 4 on the case 1, liquid crystal lens 3 is connected with Chang Liang/often black model selection button 6 by control module 5 and conversion starts button 7, control module 5 is connected with supplying cell 8, and Chang Liang/often black model selection button 6 and conversion start button 7 and be installed on the handle 4.

Wherein, normal bright pattern is under the situation of not pressing conversion startup button 7, the color of its liquid crystal lens 3 is a light color, it is the operator can watch weld from the inboard of face shield by liquid crystal lens 3 situation, start button 7 when pressing conversion, then liquid crystal lens 3 work become dark color, and can start welding gun and weld this moment.

And often black pattern is meant under the situation of not pressing conversion startup button 7, and the color of its liquid crystal lens 3 is dark, and promptly the operator can weld workpiece this moment, when needs are watched weldering place situation, presses conversion and starts button 7, and then liquid crystal lens 3 becomes light color.

The invention is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
