Abstract
The utility model belongs to welding guard tools, and relates to a welding protection cover, which comprises a smoke and arc collection cover. A sight glass is arranged in the middle of the smoke and arc collection cover, a handle is arranged on the lower portion of the smoke and arc collection cover, a vacuum cavity or a plurality of vent ducts occupy the whole interior of the smoke and arc collection cover, suction grooves or suction holes communicated with the vacuum cavity or the vent ducts are disposed on one side, facing a welding part, of the smoke and arc collection cover, and the vacuum cavity or the vent ducts are connected with an exhaust device through air pipes. The welding protection cover has the advantages that the cover is simple in structure and convenient to use, eyes and faces can be effectively protected from injury by electric arc and sparks, welding smoke can be sucked, dust removing efficiency is high, workers' operating environment can be kept away from pollution by welding smoke, and the cover is safe and reliable and beneficial to human health.
Description
Technical field
This utility model belongs to the electric welding protector, relates to a kind of electric welding protective cover.
Background technology
The effect of common electric welding protective cover is to prevent arclight and spark injury eyes and face, and is inoperative to the welding fume that prevents to be harmful to health, and therefore needs to improve.
Summary of the invention
This utility model provides a kind of electric welding protective cover simple in structure, esy to use, safe and reliable in order to remedy the deficiency of prior art.
This utility model is realized through following technical scheme:
The electric welding protective cover of this utility model; Its special character is: comprise collection flue dust and arc light cover; There is visor at its middle part, and handle is arranged at its bottom, and its inner body is negative pressure cavity or is provided with some breather lines; Its one side towards weldment is provided with several air-breathing groove or suction holes of communicating with negative pressure cavity or breather line, and negative pressure cavity or breather line connect extractor fan through trachea.
The electric welding protective cover of this utility model, preferred version do, collection flue dust and arc light cover are peviform, and its one side towards weldment is a concave surface, and its one side away from weldment is a convex surface.
The electric welding protective cover of this utility model, preferred version do, the tubular that handle is inner hollow forms exhaust tube, and negative pressure cavity is connected extractor fan through exhaust tube with trachea successively.
The electric welding protective cover of this utility model, the one side away from weldment of collection flue dust and arc light cover is equipped with the face shield of shared same visor with it, face shield and collection flue dust and the opposing setting of arc light cover.
The beneficial effect of this utility model is, and is simple in structure, easy to use; Effectively prevent arclight and spark injury eyes and face, can absorb welding fume, efficiency of dust collection is high; Can keep workman's working environment not receive the pollution of welding fume, safe and reliable, be of value to health.
Description of drawings
Fig. 1 looks sketch map for the master of this utility model.Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
Among the figure, 1 concave surface, 2 convex surfaces, 3 visors, 4 handles, 5 negative pressure cavities, 6 air-breathing groove or suction holes, 7 face shields.
The specific embodiment
Accompanying drawing is a kind of specific embodiment of this utility model.
The electric welding protective cover of this utility model; Comprise collection flue dust and arc light cover; There is visor 3 at its middle part, and handle 4 is arranged at its bottom, and its inner body is negative pressure cavity 5 or is provided with some breather lines; Its one side towards weldment is provided with several air-breathing groove that communicates with negative pressure cavity or breather line or suction holes 6, and negative pressure cavity or breather line connect extractor fan through trachea.The tubular that handle 4 is inner hollow forms exhaust tube, and negative pressure cavity 5 is connected extractor fan through exhaust tube with trachea successively.Collection flue dust and arc light cover are peviform, and its one side towards weldment is a concave surface 1, and its one side away from weldment is a convex surface 2.The one side away from weldment of collection flue dust and arc light cover is equipped with the face shield 7 of shared same visor with it, face shield and collection flue dust and the opposing setting of arc light cover.
This protective cover is in method for using:
The concave surface of collection flue dust and arc light cover with control flue dust and arc light, prevents the diffusion of flue dust and arc light towards the electric welding workpiece when 1, using;
2, be negative pressure cavity between the concave surface of collection flue dust and arc light cover and the convex surface, several breather lines are perhaps arranged between concave surface and the convex surface, when bleed in the outside, gas can unimpededly move about wherein;
3, the inner surface of collection flue dust and arc light cover can be provided with several air-breathing groove or suction holes as required, communicates with negative pressure cavity, when negative pressure cavity produces negative pressure under the effect of extractor fan, absorbs welding fume through air-breathing groove or suction hole;
4, the double exhaust tube of doing of handle is connected with negative pressure cavity, is communicated with outside exhaust equipment through connecting device;
5, but collection flue dust and arc light cover are preferably peviform, go back other shapes such as tabular.Face shield shown in the drawings is not essential.
After exhaust equipment was opened, this novel electric welding protective cover can be brought into play ideal role.
