The technical scheme of the scheme is further described through the specific embodiments with reference to the accompanying drawings.

A welding helmet comprising: a mask body 1, a strap structure 2 and a support rod 3;

the binding band structure 2 and the supporting rod 3 are respectively arranged on the mask main body 1;

the strap arrangement 2 comprises: a fixing strap 21 and a locking strap 22;

a first end of the fixing strap 21 is fixed under the mask body 1; a first end of the locking strap 22 is secured to the underside of the mask body 1; a second end of the fixing strap 21 is connected with a second end of the locking strap 22 to form a wrist fixing opening 20; the supporting rod 3 is arranged below the mask main body 1, and the supporting rod 3 is provided with a vertical rod 31; the wrist fixing port 20 is oriented transversely between the upper and lower ends of the vertical rod 31.

This scheme provides a welding protective mask, it is fixed to the wrist through bandage structure 2 to fix the position of mask main part 1 through the wrist when the workman carries out welding work, can avoid the hand to hold backing rod 3 for a long time, solved prior art's welding and need hold backing rod 3 for a long time and can not control the problem of hand auxiliary welding.

Specifically, the first end of the fixing strap 21 and the first end of the locking strap 22 are respectively connected to the mask body 1, and the second end of the fixing strap 21 and the second end of the locking strap 22 may be fixed by a known means to finally combine them to form the wrist fixing port 20 so as to fix the wrist of the worker through the wrist fixing port 20, for example, may be fixed by a jig, snap-fit fixation, elastic fixation, or the like; the wrist securing aperture 20 extends laterally; while wrist securing port 20 is oriented transversely to vertical bar 31 of brace 3; in one embodiment, when a worker needs to weld and only needs to operate with one hand, the vertical rod 31 can be selectively held according to the needs, so that the angle of the mask main body 1 can be conveniently adjusted; this embodiment is most convenient when operated with one hand; in one embodiment, when the worker does not need to weld, the vertical rod 31 can be released, the worker does not need to place the mask body 1 on the ground, the fingers can freely move, and the work of matching the hands can be performed; in one embodiment, when a worker needs to weld and the welding work is performed by matching the left hand with the right hand, the vertical rod 31 can be released, and the wrist angle can be adjusted, so that the mask body 1 can be adjusted to an optimal angle as much as possible, and the left hand and the right hand can be matched and processed simultaneously.

Preferably, the supporting rod 3 comprises: a movable bar 32 and the vertical bar 31;

the vertical rod 31 is connected to the movable rod 32; the movable rod 32 is movably connected to the mask body 1, and drives the vertical rod 31 to move to be aligned with or deviated from the wrist fixing opening 20.

The movable rod 32 is connected to the mask body 1 in a relatively rotatable manner or connected to the mask body 1 in a relatively movable manner; when the movable rod 32 moves, it can drive the vertical rod 31 to deviate from the wrist fixing opening 20, so that the whole supporting rod 3 is far away from the hand of the worker, and the processing is prevented from being hindered. At the same time, the movable rod 32 can be adjusted to move the vertical rod 31 to be aligned with the wrist fixing opening 20, so that the hand-held operation of the worker is facilitated.

Preferably, the movable rod 32 is rotatably connected to the mask body 1 and drives the vertical rod 31 to rotate.

The scheme can set up the pivot on movable rod 32, connects in mask main part 1 through the pivot, and then drives vertical pole 31 through movable rod 32 and revolute the pivot and rotate as the axle center, makes vertical pole 31 rotate to with the part straight line alignment wrist fixed port 20 between the both ends and deviate from in wrist fixed port 20. This operation may be actuated by a finger or by the weight of the movable bar 32.

Preferably, the strap arrangement 2 further comprises: a lock collar 23, a fixed male portion 24 and a fixed female portion 25;

the second end of the fixing strap 21 is fixed with the lock ring 23; the fixing male portion 24 and the fixing female portion 25 are respectively provided to the locking strap 22; after the locking strap 22 passes through the locking collar 23, the fixing male part 24 is fitted to the fixing female part 25.

The locking ring 23 is arranged at the second end of the fixing strap 21, and after the locking strap 22 passes through the locking ring 23, the fixing male part 24 of the locking strap 22 can be matched with the fixing female part 25 so as to form a wrist fixing opening 20 between the fixing strap 21 and the locking strap 22; at the same time, the fixing female part 25 can be arranged in a plurality of ways to be matched with the fixing male part 24 at different positions so as to lock the bandage structure 2 at the position of the wrist, thereby improving the fixing stability of the wrist.

Preferably, the male and female fixing parts 24 and 25 are respectively velcro tapes.

When the male and female fixing portions 24 and 25 are velcro tapes, respectively, they may be distributed along the lengths of the fixing strap 21 and the locking strap 22, so that they may be set larger in length and width; when the male fixing part 24 and the female fixing part 25 are used as magic tapes and are matched with each other, the larger magic tape can further improve the contact area between the two sections of the locking strap 22, so as to improve the fixing force, further enable the strap structure 2 to be tightly attached to the wrist, and avoid the downward rotation of the mask body 1 under the condition of not holding the supporting rod 3.

Preferably, the method further comprises: a spacer 4;

the male fixing portion 24 and the female fixing portion 25 are simultaneously disposed on one surface of the locking strap 22, and the spacer 4 is disposed on the other surface of the locking strap 22.

The spacer 4 is arranged on one surface of the locking belt 22, so that the wrist can be protected when the wrist needs to be protected, the wrist is prevented from being hurt in the welding process, and the protection effect is improved.

Preferably, the spacer 4 is further disposed outside the fixing band 21.

The spacer 4 is disposed on the outer ring side surface of the wrist fixing opening 20, so that the whole wrist can be protected, and accidental injuries such as spark dust, article falling and the like can be reduced. Meanwhile, the welding protective mask can be abutted against the workbench through the spacer 4 so as to increase the friction force between the welding protective mask and the workbench surface and limit the welding protective mask on the workbench surface.

The technical principle of the present solution is described above in connection with the specific embodiments. The description is only intended to explain the principles of the present solution and should not be construed in any way as limiting the scope of the present solution. Based on the explanations herein, other embodiments of the present solution will be apparent to those skilled in the art without undue burden, and such modifications will fall within the scope of the present solution.
