Description of drawings
Fig. 1 is an overall structure sketch map of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: on cover body 15, offer sight vane, on the cover body 15 of sight vane inboard, be set with slide rail 7, slidely connect the eyepiece 22 that cooperates with sight vane in the chute 10 of slide rail 7, the lower end of eyepiece 22 is connected with connecting rod 5, connecting rod 5 sliding plugs are in the pedestal 2 that fixedly installs, on pedestal 2, be hinged with draft link 20 by bearing pin 1, be hinged with upper pendulum bar 16 on the connecting rod 5, described draft link 20 and upper pendulum bar 16 intersect to form " X " shape and the bearing pin 18 by the place, cross point with they hinged one, in cover body 15, be provided with the resilient mounting of eyepiece 22, on cover body 15, also be provided with carried device.
Described carried device is the cross bar 13 that is fixed in directly over the sight vane, is provided with the coupler body 14 that is used for fixing on working cap in cross bar 13 ends, and perhaps according to the difference of working cap shape and structure, this carried device can be done corresponding change.
Be plugged with protection lens 8 in sight vane, the complete covering protection lens 8 of described eyepiece 22 sizes can effectively be protected eyepiece 22, and the high-temperature flue gas that produces in the time of also can preventing electric welding sees through sight vane injury operator facial skin.
Be provided with connection strap 6 in the bottom of eyepiece 22, eyepiece 22 is connected with connecting rod 5 upper ends by described connection strap 6.The resilient mounting of eyepiece 22 comprises the installation cross bar 12 that is fixedly installed on the cover body 15 or on the slide rail 7, is provided with lug 9 is installed on connecting rod 5, is provided with back-moving spring 11 between installation cross bar 12 and installation lug 9.The two ends of the resilient mounting of eyepiece 22 also can be arranged on draft link 20 and the upper pendulum bar 16.
Be provided with bulge loop 4 on connecting rod 5, upper pendulum bar 16 is hinged by bulge loop 4 and connecting rod 5, is provided with catch 3 near bulge loop 4 lower surfaces on the connecting rod below the bulge loop 45, avoids connecting rod 5 too drop-down, makes back-moving spring 11 follow the string too early.
Be provided with handle 21 in cover body 15 bottoms, make this utility model can use as existing common welders' mask when need not with 22 opening and closing of mouth control eyepiece.
During use; earlier coupler body 14 is worn on working cap; mouth will on sting sheet 17 with under sting sheet 19 contain into; firmly sting in the interlock sheet 17 and under sting sheet 19 and make that angle diminishes between draft link 20 and the upper pendulum bar 16; this moment, connecting rod 5 was by drop-down and then eyepiece 22 is drop-down; expose protection lens 8; the operator can by protection lens 8 clear see need weld and with welding rod near this place; when the needs that are about to the contact target workpiece when electrode tip weld everywhere; unclamp mouth; make connecting rod 5 under the effect of back-moving spring 11, upwards draw, and then eyepiece 22 rising covering protection lens 8, can carry out welding operation.And control eyepiece 22 away from and covering protection lens 8 processes in need not with Rhizoma Gymnadeniae with; can weld unfixed target piece so wear such welders' mask; can this workpiece be fixed with a hands during welding, the welders' mask that prior art is mentioned must have the stranger to be helped in welding during this type of workpiece can to realize.So welders' mask of the present utility model has the bigger scope of application.And form " formula nictation " with eyepiece 22 folding conditions with face control protection lens 8.
