Description
Technical field
This utility model relates to a kind of welding mask.
Background technology
At enterprise welding scene, eyes and welding slag splash and are easy to generate scald because the high light that welding is sent can be burnt, so the operator must wear the mask of being furnished with sunglasses.Conventional masks operation has two big shortcomings: must hold the handle of mask when 1, welding, and can only be with a hands during operation.2, when not welding, must take away mask, can't see any object because the sunglasses band.
The utility model content
Technical problem to be solved in the utility model provides a kind of welding mask of grasping of not needing, and makes the welder can the bimanualness soldering appliance.
In order to solve the problems of the technologies described above, technical scheme provided by the utility model is: a kind of welding mask comprises cover body, Tou Quan, sunglasses, pin hook mechanism and stay cord; The head circle is fixed in the cover body; The front end of described cover body is provided with window, and the top of described sunglasses both sides is hinged on the window top of cover body; The top of the front end of described pin hook mechanism and sunglasses one side is hinged; One end of described stay cord is connected with the pin hook mechanism, and the other end is fixed in the cover body; The position that described stay cord is installed can catch welder's chin.
A kind of welding mask also comprises snap device; Described snap device comprises buckle, torsion spring and support; Described support is fixed on the outside of cover body; Described buckle keeps hook portion to be installed in the support up all the time by torsion spring; The bottom of described sunglasses one side be provided with can with the bayonet lock that is clasped.
Described pin hook mechanism comprises first connecting rod, second connecting rod and extension spring; The front end of described first connecting rod passes cover body, and hinged with the top of sunglasses one side, and the rear end of first connecting rod and the front end of second connecting rod are hinged, and the second connecting rod rear end is connected with the upper end of extension spring, and the lower end of extension spring is connected with cover body; Middle part and the cover body of described second connecting rod are hinged; One end of described stay cord is connected with second connecting rod, and this junction point is positioned at the place ahead of the pin joint of two connecting rods and cover body.
Described head circle adopts the structure of adjustable size.
One end of described head circle is fixedlyed connected with cover body by a coil support, and it is fixedly connected that the other end is fixed on cover body by adjusting knob.
After having adopted technique scheme, the utlity model has following beneficial effect: the position that (1) stay cord of the present utility model is installed can catch welder's chin, as gauge tap, chin moves down when opening one's mouth with chin, the pulling rope band, by the upset of pin hook mechanism control sunglasses, sunglasses roll up when not welding, and sunglasses are turned down during welding, and the welder can use bimanualness, and just can switch sunglasses by demand without hands, very convenient.
(2) buckle of the present utility model keeps hook portion to be installed in up all the time in the support by torsion spring, and this structure makes mouth of the every opening and closing of welder, and sunglasses just switch between two positions, and do not need to open one's mouth always and shut up and control.
(3) head circle of the present utility model adopts the structure of adjustable size, can be applicable to the welder that head size is different.
(4) end of head circle of the present utility model is fixedlyed connected with cover body by a coil support, and a coil support can avoid head circle and pin hook mechanism to interfere.
