Problems solved by technology

It not only affects the construction speed and quality, but also brings greater harm to the operator's eyes
At present, the existing eye protection devices mostly use dark glass to reduce the brightness of the light entering the eyes, but it still cannot solve the problem of local glare

Embodiment Construction

[0020] The present invention will be further described below in conjunction with specific examples.

[0021] see figure 1 , a kind of eye protection device of the present invention, comprises:

[0022] A mask 1, a handle 5 fixed on the bottom of the mask 1 and a lens 3 fixed in an observation port opened on the top of the mask 1, the lens 3 is a polarizer that filters the scattered light in the light beam, and only allows light in a fixed direction to pass through , so that the eyes receive the incident light along the same direction, so that the scene looks soft and not dazzling; the number of three lenses is two, stacked, and are respectively rotatably fixed in the observation port 8 through the bearing 2, and also includes a Through the automatic adjustment unit of the transmission connection between the bearing 2 and the lens 3, the automatic adjustment of the rotation of the two lenses 3 is realized to ensure that the amount of light passing through the two lenses 3 is a...

Abstract

The invention discloses an eye-protecting device which comprises a mask, a handle fixed at the bottom of the mask and lenses which are inside an observation opening and are formed on the upper portion of the mask. The eye-protecting device is characterized in that the lenses are polarized lenses, and the number of the lenses is two. The lenses are placed in a stack mode, and are fixed in the observation opening through bearings in a rotating mode. The eye-protecting device further comprises an automatic adjusting unit connected with the lenses through the bearings in a transmission mode and a power supply supporting power to the automatic adjusting unit. The eye-protecting device ensures that observed images are soft and the brightness of the observed images is uniform. Because angles of the lenses can be automatically adjusted, even a user moves the angles of the lenses or the angles change by welding, visual images can still keep appropriate brightness. The eye-protecting device has the advantages of being fast in adjustment, free of dark space and capable of protecting eyesight.

Description

technical field [0001] The invention relates to a protective gear, especially an eye protection device. Background technique [0002] During the electric welding process, dazzling light will be emitted, which will directly stimulate the eyes, make the eyes feel dazzled, tired, unable to see things for a long time, and damage the eyes. It not only affects the construction speed and quality, but also brings greater harm to the operator's eyes. Existing eye protection device mostly adopts dark glass to reduce the brightness of entering the eye light, but still can not solve the problem of local light dazzle. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, and provide a kind of eye protection device, which realizes a kind of eye protection device that makes the eye image soft and uniform in brightness. Since the lens angle can be automatically adjusted, even when the user moves or electric welding The chang...
