Abstract
The utility model provides a brake type shading and protecting device for electric welding, and the utility model is used for protecting the eyes and faces of electric welders. The utility model comprises a face mask provided with a piece of transparent sheet glass and a piece of dark shading glass which can be moved upwards and downwards and a pair of electrode holders which is used by matching with the face mask. The utility model is characterized in that a glass lifting mechanism comprising a connecting rod arm, a spring and a brake controlling wire which are connected by a steel wire is arranged under the window frame of the inner side of the face mask. The brake controlling wire is connected with the manual brake of the electrode holders or an electromagnet device, and the assembly and disassembly are convenient. When the utility model is used, the manual brake is pressed by a thumb, and the dark shading glass is pulled down by the function of the glass lifting mechanism to achieve the purpose of advanced shading. The utility model has the advantages of stable and reliable working and low cost.
Description
A kind of welding worker protection eyes and facial lock formula electric welding sunscreen protection device of being used for belongs to labor protection utensil technical field.
The electric welder's helmet of electric welder's use at present, mostly be hand-held, also wear open-close type, common defects is: it is to be fixed on the face shield that the deep-color lens that order uses is protected in shading, in case stop welding in the time of need watching the welding situation, will remove face shield, influence work efficiency, also make eyes be subjected to the infringement of arclight easily, it is healthy to influence the workman.
I am in the light-operated sunscreen protection device of electric welding of last Apr application.Also not ideal enough, can't shift to an earlier date shading, eyes are also vulnerable.
The purpose of this invention is to provide one and realize control with the operator, can the novel lock formula of light blocking electric welding sunscreen protection device in last second occur than arclight, eyes at all can not be subjected to the irradiation of arclight.
The technical solution of the utility model is: include clear glass eyeglass (3), can move up and down the face shield (1) and the matching used with it electrode holders (10) of dark shading eyeglass (2).Characteristics are that the eyeglass elevating mechanism that pitman arm (5), spring (6), lock control line (7) with steel wire (4) connection are formed is housed under the face shield inside window frame, and lock control line (7) is connected conveniently detachable with the manual lock (11) (or electromagnet apparatus) of electrode holders (10).Face shield (1) can be hand-held or wear-type.The wear-type face shield is connected by movable button with headband, can the quick adjustment degree of tightness, and face shield can upwards turn over and put.
Fig. 1 is the backsight structural representation of lock formula electric welding sunscreen protection device face shield.
Fig. 2 is the electrode holders perspective view.
Further specify structure of the present utility model and operation principle below in conjunction with Fig. 1～2.
Sequence number among the figure (8) is a fixed leg, and (9) are movable pulley.When not electric welding did not have arc light, the manual lock (11) (or electromagnet apparatus) in the electrode holders (10) was in off position.Spring (6) is housed steel wire (4) pushing tow upwards under face shield (1) inside window frame, it is upper to make dark shading eyeglass (2) withstand on the window frame groove.When operating welding, when welding rod is aimed at solder joint, press manual lock (11) on the electrode holders (10) with thumb, pulling lock control line (7), under the effect of pitman arm (5), by steel wire (4) the dark shading eyeglass (2) of face shield window frame inboard is left behind, reach the preceding shading purpose of weldering prerequisite.Need not manual lock, press the microswitch (omitting among the figure) in the electrode holders (10), make work of electromagnet (power supply is taken from electric welding machine), also can leave behind deep-color lens by lock control line (7), pitman arm (5), steel wire (4), reach the shading purpose.But cost is than manual lock height, and structure is more complicated.After electric welding finishes, and manual lock (or microswitch) resets, under the effect of cover spring (6), dark shading eyeglass jack-up, eyes can be observed the welding situation by clear glass.
This utility model uses through reality, and working stability is reliable, and cost is low, easily promotes.
