Abstract

The utility model relates to a protective cover for electric welding, which is an elastic and compressible cylindrical protective cover with a horn shape and is contacted and connected with a handle of an electric welding device. A piece of dark eye protecting eyeglass is embedded in one side of the protective cover, and the lower end of the protective cover is provided with two truncated cones which are overlapped in a partial hanging mode. An opening is arranged on the middle upper part of one side of the protective cover, and the opening is connected with a smoke discharging hose. When used, the protective cover is covered on a welding point, so welding arc and welding slag are enclosed in the protective cover, and an electric welder does not need to wear a protective mask. The electric welder observes welding conditions in the protective cover through the dark eye protecting eyeglass of the protective cover. Smoke gas and hot gas generated by welding process are discharged by the smoke discharging hose, fresh air enters the protective cover from a gap between the two cones on the lower part of the protective cover, and the two cones are hung and overlapped.

Description

Protective cover for welding
This utility model relates to a kind of metal arc welding and takes over control protection unit.
At present, in the metal solder operation, for preventing electro-welding arc and the welding slag that splashes, the electric welder's that burns eyes and skin need be worn the thick matter working clothing of long sleeves, wear protective mast or hands and lift protective cover.Concerning the electric welder, both sultry, inconvenient again.
The purpose of this utility model provides a kind of protective cover, and it no longer is to go protection again after waiting arclight scattering and welding slag to splash, but just in the welding trigger point it is covered, do not allow its scattering everywhere, endanger electric welder and near personnel's eyes, skin.Therefore the staff also can remove from and wears protective garment, wears protective mast, and perhaps hands is lifted the tired of protective mast.
The purpose of this utility model is achieved in that at electric weld handle and connects a trumpet type tubular protective cover on hand.The lower end edge periphery of cover is equipped with Magnet, by Magnet protective cover is adsorbed on the metal weldment gently.The cover lower end is two truncateds cone, partly built on stilts overlapping forming.Like this, arc light misfires in the cover, and the cover outer air can enter in the cover.Open on protective cover one lateral deviation flatly,,, protect welding worker health so that electric welding flue gas, steam detach at a distance at thermal head effect lower edge flexible pipe in will cover with one hose connection.Protective cover one side studs with a dark screening glass, and the electric welder can see electric welding situation in the cover by this eyeglass.The protective cover upper end simply contacts crimping with the electric welding handle or connects with weak magnetic is attached, and cover body top is flexible, compressible, allows handle along with progress, the welding rod of electric welding are shorter and shorter, and handle can be indiscriminately ad. as one wishes near welding work pieces.
Because adopt above-mentioned electric welding protective cover, arc light is closed in the cover, welding slag also splashes no longer everywhere, and the flue gas that produces in the welding process, steam are also discharged along pipeline.Therefore the electric welder no longer needs to wear protective mast or hands act face shield, and the health of also needn't worrying can be subjected to burning of arc light or welding slag, also no longer is subjected to welding fire-cureing of flue gas, steam.Equally, the other staff in the welding building site also no longer need deliberately to turn aside, avoid arc light.Also can avoid causing fire because of welding slag splashes.Because the improvement of labor condition, welding quality and work efficiency also will improve.
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is the sketch map of an embodiment of the present utility model.Among the figure: 1, welding work pieces 2, weld seam 3, protective cover 4, Magnet 5, dark screening glass 6, smoke evacuation flexible pipe 7, welding rod 8, electric welding handle 9, power supply wiring.
In the present embodiment, before the welding, the protective cover cover to weld, by the Magnet of protective cover periphery, is adsorbed on the workpiece 1 gently.The handle 8 that will clip welding rod 7 is then pressed to protective cover upper end open place, and contact is connected airtight together.This moment, welding rod pointed to the commissure, sent arc light, and the electric welder observes the interior welding situation of cover by the dark screening glass that is set on the cover.The steam that produces in the welding, flue gas under the thermal head effect, enter the smoke evacuation flexible pipe and discharge, and meanwhile, under the suction function, extraneous fresh air is inhaled in the cover by the gap between the double-deck horn mouth of protective cover bottom, has strengthened smoke discharging effect in cover.After a root bead bar uses up, mention handle, also upspring in protective cover top thereupon, and handle is raised again, just can throw off with cover body, and handle is replaceable welding rod, repeats above-mentioned operation again, proceeds welding.
In another embodiment, certain some of cover is made able to turn on or off, so that the window that can pass through to open before the electric welding is observed the situation of welding rod aligning weld seam etc.Then, close window, begin welding.
In the 3rd embodiment, protective cover bottom connects a circle and makes with asbestos one class material, can prevent fires, has the skirt cover of flexibility, its shirt rim carry magnet.Such electric welding protective cover is applicable to workpiece such as welded reinforcement, and protective cover shirt rim pine loose ground wraps weld during welding, prevents that welding slag from splashing everywhere.
