Description
Technical field
The present invention relates to a kind of adjusting device, specifically, relate to a kind of welding mask adjusting device.
Background technology
Welding mask refers to the instrument that plays protection operating personnel safety in welding operation.It is made up of observation window, optical filter, screening glass and face shield etc.It is mainly divided into hand shield, wear-type face shield, helmet of head-guard and safety helmet front-hanging lens on glasses face shield Four types.Wear-type face shield is the most popular at present, but owing to there being different size differences between wearer, after welding mask, often need to regulate according to oneself requirement the position between face shield and head hoop wearing, existing wear-type face shield needs first specially unclamp hold-doun nut in the time regulating, and regulates behind position tightening nuts again.Adjustment process is not only loaded down with trivial details, and not easy to operate.Therefore, need a kind of new technical scheme to solve the problems referred to above.
Summary of the invention
The object of this invention is to provide a kind of adjusting device, utilize this adjusting device can regulate easily the position between welding mask and head hoop, welding mask and wearer's face, overcome existing welding mask and use inconvenient defect.
The technical solution used in the present invention is:
A kind of welding mask adjusting device, comprise head hoop, the lateral symmetry of described head hoop is provided with left engaging lug and right engaging lug, a described left side, on right engaging lug, be respectively provided with a hold-down screw, on described hold-down screw, be disposed with stop bit part, regulating part, pressure cap and hold-doun nut, the root of described hold-down screw is square column type structure, the interstitial hole of described pressure cap is the square structure that can match with the root of hold-down screw, on described stop bit part, be provided with and be the fan-shaped tooth I arranging, one side of described regulating part is provided with the tooth II matching with the tooth I on stop bit part, on the another side of described regulating part, be provided with buckle, on described head hoop, be provided with multiple adjustment pins that circular arc is arranged that are, the top of described stop bit part is provided with the adjustment hole matching with described adjustment pin.
Further, be provided with three installation positions on described left and right engaging lug, each installation position all can coordinate with hold-down screw installation.
Further, on described regulating part, be provided with the limited block matching with stop bit part.
Advantage of the present invention is: easy accessibility, regulate simple and practical, to meet each wearer instructions for use.

The specific embodiment
As shown in Figures 1 to 7, a kind of welding mask adjusting device, comprise head hoop 1, be provided with left engaging lug 2 and right engaging lug 3 in the lateral symmetry of head hoop 1, on left and right engaging lug, be respectively provided with a hold-down screw 4, on hold-down screw 4, be disposed with stop bit part 5, regulating part 6, pressure cap 7 and hold-doun nut 8.In order to prevent that pressure cap 7, along with face shield rotates, is designed to square column type structure by the root of hold-down screw 4, and the interstitial hole of pressure cap 7 is also designed to the square structure that can match with the root of hold-down screw 4.On stop bit part 5, be provided with and be the fan-shaped tooth I9 arranging, on a side of regulating part 6, be provided with the tooth II10 matching with the tooth I9 on stop bit part 5, on the another side of regulating part 6, be provided with buckle 11, between regulating part 6 and stop bit part 5, there is like this friction, and face shield 16 is arranged on buckle 11, in the time regulating face shield, be greater than the frictional force between regulating part 6 and stop bit part 5 as long as rotate the power of face shield, face shield is just rotated, easy to adjust quick.In order to guarantee face shield scalable in rational scope, on regulating part 6, be provided with the limited block 15 that can match with stop bit part 5, this limited block 15 rotates regulating part 6 in certain scope.In order to increase the range of accommodation of face shield, on head hoop 1, be provided with multiple adjustment pins 12 that circular arc is arranged that are, be provided with the adjustment hole 13 matching with described adjustment pin 12 at the top of stop bit part 5.In order further to regulate face shield and facial distance, on left and right engaging lug, be provided with three installation positions, each installation position all can coordinate with hold-down screw installation.
The present invention, in the time of assembling, is arranged on face shield 16 on buckle 11, then loads onto pressure cap 7 and hold-doun nut 8, and tightens hold-doun nut.Face shield 16 cooperatively interacts owing to being the fan-shaped tooth II arranging on stop bit part 5 and regulating part 6, so can rest on the angle position of any needs.
In addition, in the time that we need to be by face shield translation-angle position, only need to be just passable to the position needing with pulling face shield, the tooth of arranging because fan-shaped can be fixed on face shield on this position.Because pressure cap 7 matches with the square structure root of hold-down screw 4, so face shield when rotated, pressure cap 7 and hold-doun nut 4 can not rotate.
