Abstract
The utility model relates to a louver window type automatic protective electric welding mirror which is composed of a louver window type electric welding protective mirror and an automatic control device, wherein the louver window type electric welding protective mirror is formed into a movable vane by a plurality of filters for electric welding, and a piece of transparent glass is used as a casing; the automatic control device is formed and directly connected into an electric loop by a current mutual inductor, connecting conducting wires and an electromagnetic power mechanism. The electromagnetic power mechanism is arranged at the side of the glass casing, and the electromagnetic power mechanism and the louver window type electric welding protective mirror are combined into a whole to drive the filters of the electric welding protective mirror to rotate. When the electric welding is stopped, the filters are parallel to the line of sight and an operator can clearly see a target through the transparent glass. When the electric welding starts, the current mutual inductor which is sheathed on an electric welding handle wire inducts electric welding current which passes through an electric welding handle, induced current is generated directly to provide power source to the electromagnetic power mechanism and the filters are driven to vertical to the line of the sight. Electric welding strong light is weakened by the filters, and the eyes of the operator can be protected quickly and reliably.
Description
Affiliated technical field:
This utility model relates to a kind of automatic protection electric welding mirror, especially fast, reliable, cost is low.
Background technology:
Tradition electric welding mirror, inconvenience is used in the moving protection of armrest, is difficult to grasp, and easily hinders eyes, influences welding quality.Some automatic control electric welding mirrors are also arranged, but have variety of issue, or governing speed is slow, or unreliable, or cost cost height, or use inconvenience or the like, cause to be difficult to carry out and to promote.
Summary of the invention:
This utility model has overcome above-mentioned shortcoming, with simple principle and extremely low cost make the electric welding mirror realized fast, reliably, the purpose of automatic protection.
The technical scheme that its technical problem that solves this utility model adopts is: mainly be made of venetian blind type arc welder's glasses and self-con-tained unit two parts.The venetian blind type arc welder's glasses is made one group of movable blade by several pieces electric welding with optical filter, does shell with clear glass, stops the electric welding state, and optical filter is parallel with sight line, and the operator can see through clear glass and be clear that target; The electric welding state, optical filter is vertical with sight line, and the electric welding high light sees through optical filter and obtains decay, and operator's eyes are protected.
Self-con-tained unit be used for the automaticallying switch two states of above-mentioned arc welder's glasses---stop electric welding state and electric welding state.Self-con-tained unit is made up of current transformer, connection lead and electromagnetic power mechanism.Current transformer is enclosed within on the welding leads near the electric welding handle, current transformer, and by connecting the lead electric loop of formation that links to each other with electromagnetic power mechanism, the be integrated rotation of the optical filter that is used for driving arc welder's glasses of electromagnetic power mechanism and venetian blind type arc welder's glasses.During electric welding, electric current is through the electric welding handle, and current transformer produces electric current and directly drives electromagnetic power mechanism, and arc welder's glasses is switched to the electric welding state, and optical filter is vertical with sight line; When stopping electric welding, current transformer loses drive current, and electromagnetic power mechanism resets by back-moving spring, and arc welder's glasses is resetted to switch to stops the electric welding state, and optical filter is parallel with sight line.So self-con-tained unit can in good time, quickly and reliably be controlled the switching of the two states of arc welder's glasses automatically, thereby reaches the purpose of protection operator eyes.
Use for convenience, current transformer is provided with plug receptacle with the lead that is connected between the electromagnetic power mechanism, and current transformer can be connected or separate easily with electromagnetic power mechanism.
Electromagnetic power mechanism is provided with manual control machine and closes, and when breaking down in order to self-con-tained unit, venetian blind type automatic protection electric welding mirror still has the safeguard function of protection electric welding mirror.
Description of drawings:
Further specify below in conjunction with accompanying drawing this utility model.
Fig. 1 is that this utility model stops the electric welding state, venetian blind type arc welder's glasses front view.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is this utility model electric welding state, venetian blind type arc welder's glasses front view.
Fig. 4 is the B-B cutaway view of Fig. 3.
Among the figure, 1. clear glass outer housing, 2. optical filter.
The specific embodiment:
Optical filter 2, several pieces are installed in parallel in the clear glass outer housing 1, as shutter, constitute the venetian blind type arc welder's glasses, and the venetian blind type arc welder's glasses is installed in and can replaces old-fashioned electric welding mirror with on the electric welder's helmet on operator's head.Several pieces optical filters 2 are connected by gangbar in the venetian blind type arc welder's glasses, can rotate simultaneously.Electromagnetic power mechanism is closed by solenoid, back-moving spring and manual control machine and forms, and is installed in clear glass outer housing 1 side, connects and the drive gangbar, drives optical filter 2 by gangbar and rotates.
During electric welding; the electric welding electric current is through the electric weld handle line, and the current transformer that is enclosed within on the electric weld handle line produces faradic current, passes to electromagnetic power mechanism by connecting lead; power source is provided; solenoid produces power, drives gangbar, and gangbar will drive all optical filters and rotate; make optical filter vertical with sight line; as Fig. 3 and Fig. 4, the electric welding high light sees through optical filter and obtains decay, and operator's eyes are protected.
When stopping electric welding, the electric welding current vanishes, solenoid runs out of steam, electromagnetic power mechanism is reset spring reset to initial condition, gangbar drives all optical filters and rotates, it is parallel with sight line to make optical filter reset to initial condition, and as Fig. 1 and Fig. 2, the operator can see through clear glass and be clear that by the electric welding target.
Manual control machine in the electromagnetic power mechanism closes, can be when self-con-tained unit breaks down, venetian blind type automatic protection electric welding mirror can not be automatic, rotates but still can manually control optical filter, and venetian blind type automatic protection electric welding mirror still has the safeguard function of protection electric welding mirror.
Connect lead and make of scalable helix tube type cable, there is patch plug at two ends, and plug receptacle places electromagnetic power mechanism side summation current transformer side, can be easily separately with current transformer, connection lead, electromagnetic power mechanism, and convenient the use.
