Description

A mouth-held welding mask

technical field

The utility model relates to the field of welding appliances, in particular to a mouth-held welding mask.

Background technique

A welding mask is a tool used to protect the safety of workers during welding and cutting operations. It is a high-tech product integrating optics, electronics, human body, materials and other disciplines. High-quality LCD and glass-coated combination are used as shading lenses. The light sensing system on the lens can instantly detect the generation and disappearance of arc light during electric welding, and quickly drive the liquid crystal to shading and change color to achieve safe and effective filtering of harmful light, thereby protecting welders. Eyes, face to avoid arc radiation damage.

The welding mask is composed of observation window, optical filter, protective sheet and mask. It is generally divided into four types: hand-held mask, headband mask, helmet mask and helmet front-hanging glasses mask. The hand-held mask needs to occupy one hand of the user, thereby reducing the welding accuracy and welding efficiency; the head-mounted mask Because it is often necessary to lower the head when working, it is easy to slip off; because the center of gravity of the helmet is forward, it is also very easy to slip off when the user bows the head to perform welding work, which poses a safety hazard; Most of the face is directly exposed, which poses safety hazards during welding operations. To sum up, a welding mask that can not only ensure the safety of the user, but also free hands and improve working efficiency is needed.

As a further improvement of the utility model, the mouth holding part is a sphere, which is fixedly connected with the welding mask body through a fixing column, and the radius of the sphere is less than 1 cm.

3. Beneficial effect

Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

(1) A mouth-held welding mask of the present invention comprises a welding mask body and a mouth-holding part. The mouth-holding part is located below the observation window of the welding mask body, and can be used to hold the mouth when performing welding operations. The holding part fully solves the problem of hands, which not only ensures the accuracy of welding, but also improves the work efficiency of welding operators.

(2) A mouth-held welding mask of the present utility model has a protrusion matching the shape of the nose between the mouth holding part and the observation window, and the protrusion direction of the protrusion is outward. This structural design enables the welding mask to fully It perfectly fits the human face, does not affect the normal breathing of the user, and is safe and efficient.

(3) A mouth-holding type welding mask of the present utility model, the mouth-holding part is a horizontal type II, and the longitudinal distance is less than 2cm. , The body of the welding mask is not easy to skew, which ensures the stability during use. By adjusting the front and rear positions of the upper and lower rows of teeth, the inclination of the welding mask body is adjusted. The adjustment accuracy is high, and it is suitable for various use environments.

(4) A mouth-held welding mask of the present utility model, the mouth-holding part is a sphere, which is fixedly connected with the welding mask body through a fixing column, and the radius of the sphere is less than 1 cm. Such a structural design fully adapts to the normal opening and closing of the mouth, The mouth holding part can be contained in the mouth, and the mouth can be closed normally, and the inclination of the welding mask body can be adjusted by adjusting the front and rear positions of the upper and lower rows of teeth. The adjustment accuracy is high, and it is suitable for various use environments.

(5) A mouth-held welding mask of the present utility model has reasonable structural design, simple principle, and is convenient for popularization and use.
