Description

Technical Field

[0001] The utility model relates to a welding protection tool, in particular to a welding protection mask. Background Art

[0002] A welding protective mask is a tool that protects workers during welding and cutting operations. The main function of a welding protective mask is to protect the eyes and face, as well as damage to the eyes caused by strong welding light, to prevent the occurrence of photoelectric eye inflammation, and to effectively prevent splashes and harmful substances from causing damage to the face during the operation, thereby reducing the occurrence of skin burns.

[0003] Existing welding protective masks include handheld welding protective masks and head-mounted protective masks. The disadvantage of handheld welding protective masks is that one hand holds the welding pliers and the other hand holds the protective mask, leaving no extra hands to assist in welding operations. The face must be covered and then removed to observe the welding effect repeatedly. The welding light may accidentally flash into the eyes, causing direct damage to the human body and reducing work efficiency. The disadvantage of head-mounted protective masks is that it is hot and humid in all seasons, the glass fogs up in winter, making it difficult to see clearly, the air permeability is poor, and the work efficiency is low.

[0004] Therefore, it is a problem worth studying to provide a welding protective mask that is light and flexible, quick to install and has good protective effect. Summary of the invention

[0005] The utility model aims to provide a welding protective mask which is light, flexible, quick to install and has good protective effect.

[0006] The purpose of the utility model is achieved in this way:

[0007] A welding protective mask comprises a handle, a base located at the top of the handle, and protective glasses detachably connected to the top of the base via a connecting mechanism, wherein the protective glasses are damped to rotate relative to the right end of the connecting mechanism, and the left end of the connecting mechanism is damped to rotate relative to the base, and the connecting mechanism comprises a connecting rod, a first connecting component located at the left end of the connecting rod and connecting the connecting rod to the top of the base, and a second connecting component located at the right end of the connecting rod and connected to the protective glasses.

[0008] The protective mirror is made of a filtering material and includes a circular shape and a polygonal shape.

[0009] The handle and the base adopt an integrated structure.

[0010] The handle and the base adopt a split structure.

[0011] The first connecting component includes a first connecting screw fixedly connected to the top of the base and located in the vertical direction, a first pad mounted on the first connecting screw, a mounting hole located on the upper surface of the first pad and located at the left end of the connecting rod, a second pad located above the mounting hole, and a first locking nut located above the second pad and threadedly connected to the first connecting screw. The first locking nut squeezes the first pad and the second pad into contact with the lower surface and the upper surface of the left side of the connecting rod respectively, so that the left end of the connecting rod can rotate relative to the first pad and the second pad.

[0012] The second connecting assembly includes an adjustment hole located on the right side of the connecting rod, a locking hole located on the protective mirror, a second connecting bolt passing through the adjustment hole and the locking hole, and a second locking nut threadedly connected to the second connecting bolt. The second locking nut and the second connecting bolt enable the right side of the connecting rod and the protective mirror to perform damped rotation.

[0013] A plurality of adjusting holes are provided, and the plurality of adjusting holes are evenly distributed along the length direction of the connecting rod.

[0014] The locking hole is located at a position deviating from the center of the circle.

[0015] The beneficial effects of the utility model are:

[0016] Quick installation: The protective glasses of the utility model are detachably connected to the base through a connecting mechanism, which is quick to install and easy to disassemble;

[0017] Lightweight and flexible: The connecting rod of the utility model can be freely turned 360° in the horizontal direction around the base, and can be positioned and fixed after turning to the set position. The protective glasses can be freely turned and positioned 360° in the horizontal direction around the other end of the connecting rod to achieve blind spot protection; it avoids the phenomenon that the protective cover constantly covers the face and then moves away to observe the welding effect repeatedly;

[0018] Simple operation: The utility model does not require any learning, and the connecting rod and the protective mirror can be rotated manually;

[0019] The utility model has good protective effect. The protective glasses are close to the welding light source, and the welding light protection area is maximized. At the same time, the direct damage to the human body caused by welding sparks and harmful waste smoke is blocked to the maximum extent. Since the protective glasses are arranged in a plane, the four seasons are hot and stuffy, and the glass is fogged in winter, which makes it difficult to see clearly, has poor air permeability, and has low work efficiency.

[0020] The utility model has strong practicability. During the operation, visual operation can be realized through the protective glasses, so the work efficiency is improved, and the direct damage to the human body caused by welding light, welding spark splashing and waste smoke is blocked to the maximum extent, thus truly realizing integrated protection.
