Description

Technical Field

[0001] The present invention relates to the technical field of protective equipment installation, and in particular to a variable light filter installation device. Background Art

[0002] In industrial production, people's faces are often harmed by high-speed particles, molten metal, chemical liquid splashes and harmful light, and various protective helmets must be used for protection.

[0003] The protective helmet is an industrial protective mask used to protect the eyes and face from dust, chemicals, heat, toxic gases, debris and other harmful substances. It is equipped with toothed knobs on the left and right of the elastic head clamp, and a large arc thin curved transparent mask is installed on the toothed knob. The large arc thin curved transparent mask can be rotated on the elastic head clamp with toothed knobs and placed on the face or the top of the head. It can be used in conjunction with a gas mask, a dust mask, and a work cap to achieve the purpose of comprehensive protection.

[0004] With the development of science and technology in today's society, the existing technology has replaced the transparent mask with a dimmer filter for shielding, which can not only block the material but also adjust the light to different light. However, in the installation process of the dimmer filter, since it needs to be connected to an external line, most of them are directly fixed and cannot be disassembled. If the dimmer filter is damaged during long-term use, the entire protective helmet needs to be replaced, which is very inconvenient. Summary of the invention

[0005] The technical problem to be solved by the present invention is that the dimmer filter in the protective helmet in the prior art is not removable. In order to overcome the above defects of the prior art, the present invention provides a dimmer filter installation device.
