Abstract

The utility model belongs to the welding protective appliance. In the case of welding with strong light, a welding mask is indispensable; however the welding mask is used by a hand when being in use, thus bring extreme inconvenience to the welding operator. The utility model discloses a welding helmet with the eyeglasses thereof can be opened or closed at will. Though a steel wire, a connecting rod, a push rod, a cross shaft and an upright post, a movable handle is connected with a movable window with the deep color eyeglasses inlaid; in this way, the welding operator can operate the movable handle to control opening or closing of the deep color eyeglasses, just by the hand of holding the welding gun or by foot, thereby one hand could be released, and the hand can then conduct such jobs as adding solders and holding weldments, to increase both the welding efficiency and welding quality.

Description

The random folding welding of eyeglass head protector

This utility model relates to the random folding welding of a kind of eyeglass head protector, as a kind of welding protective equipment, can be widely used in welding fields such as arc welding, argon arc welding.

As everyone knows, welding is the most frequently used a kind of method for metal working, but because a lot of welding processes can produce discomfort glare, so welding personnel must use the welding mask that has deep-color lens, to protect facial and eyes are without prejudice.Solder side commonly used at present is covered with two kinds: a kind of is holding type, claims the shield formula again; Another kind is a wear-type, claims the helmet formula again.The former has taken a hands because work the time is to hold with hands.Though the latter is worn on the head; but in welding process; also must go to open (, or changing welding rod) through hands commonly used or when welding (so that the protection eyes) deep-color lens that closes, that is to say that these two kinds of welding masks all need a hands and operate on it so that see clearly and put weldment.Because the another hands of welding personnel will be taken welding gun (this paper is referred to as welding gun with soldering turret, welding torch, cutting torch etc.), therefore in welding process, go to carry out such as dosing some other operations such as scolder, assurance welding work pieces with regard to unrenewable hands, not only caused inconvenience, and influenced welding quality to welding job.

The purpose of this utility model is to overcome the deficiency of above-mentioned existing welding mask, and the random folding welding of a kind of eyeglass head protector is provided.

The purpose of this utility model has been achieved in that the deep-color lens of protection eyes effect is installed on the movable window, and movable window is connected with head protector by hinge.Fixed two root posts in addition on movable window, a transverse axis is arranged on the column, transverse axis and push rod are hinged, and push rod has a spring by active pin shaft and rod hinge connection between active pin shaft and spring catch.Its structural feature also comprises: a conduit is arranged, and an end of conduit is fixed on the supporting plate, and supporting plate is fixed on the head protector, and the other end of conduit is fixed on the fixed mount.There is a steel wire conduit the inside, and of steel wire is fixed together with connecting rod, and other end and movable handle are fixed together.Movable handle is hinged by fixed pin shaft and fixed mount, and fixed mount is fixed on torch handle or other positions of being convenient to operate.

The purpose of this utility model can also reach by following technical measures: fix an elasticity lock hook on torch handle, when when holding tight movable handle, the position of movable handle is just locked by the elasticity lock hook.If movable handle is used some power slightly to the side, movable handle can break away from the restriction of elasticity lock hook, gets back to original free state position again.

Compare with existing welding mask, the utlity model has following advantage:

If 1 is installed in fixed mount and elasticity lock hook on the torch handle,, so just liberated an other hands of welding personnel just take the opening of hands may command deep-color lens of welding gun with closed.

If 2 are installed in fixed mount and elasticity lock hook on the ground, the mode of tramping with one's feet is opening with closed of may command deep-color lens, has not only liberated a hands of welding personnel, and the operation of being more convenient for.

3, because idle hands, so this hands can carry out a lot of back works, as doses scolder, holds welding work pieces etc., helps improving welding efficiency and welding quality.

The explanation of accompanying drawing drawing:

Fig. 1 is this utility model head protector and drive mechanism sketch map.

Movable handle position view when Fig. 2 opens for this utility model deep-color lens.

Movable handle position view when Fig. 3 is this utility model deep-color lens closure.

Below in conjunction with accompanying drawing 1, accompanying drawing 2, accompanying drawing 3 in detail this utility model is described in detail.

This utility model is by head protector (1), observation window (2), transparent glasses lens (3), movable window (4), deep-color lens (5), column (6), hinge (7), hinge screw (8), transverse axis (9), push rod (10), active pin shaft (11), spring (12), spring catch (13), steel wire (14), conduit (15), conduit nut (16), supporting plate (17), supporting plate screw (18), limit screw (19), central pin shaft (20), connecting rod (21), fixed pin shaft (22), fixed mount (23), jam nut (24), bolt (25), torch handle (26), movable handle (27), lock hook bolt (28), elasticity lock hook (29) is formed.

Work process of the present utility model is: with holding tight or the movable handle (27) that tramps with one's feet down, movable handle (27) spurs steel wire (14), and steel wire (14) pulling connecting rod (21) right-hand member moves up.Because a central pin shaft (20) is arranged on the connecting rod (21),,, force push rod (10) to move down by active pin shaft (11) so the left end of connecting rod (21) moves down.Again because push rod (10) and transverse axis (9) are hinged, transverse axis (9) and column (6) are fixed together, column (6) and movable window (4) are fixed together, therefore movable window (4) just along hinge (7) to following upset, cover fully so have the observation window (2) that the movable window (4) of deep-color lens (5) will have transparent glasses lens (3).Because elasticity lock hook (29) makes movable window (4) be kept closed to the position-limiting action of movable handle (27) always.If want to open movable window (4), need only use some power slightly to the side to movable handle (27), movable handle (27) just can break away from the restriction of elasticity lock hook (29), under the pulling force effect of spring (12), movable window (4) is opened, and meanwhile, movable handle (27) is also got back to original free state position.
