Description

Ophthalmic examination glasses based on electrochromic material

Technical Field

The invention belongs to the field of glasses, and particularly relates to an ophthalmic examination glass based on an electrochromic material.

Background

In the existing ophthalmic examination, the vision examination needs to be carried out on a single pair of glasses, generally, an eye chart is adopted, a person stands at a certain distance from the eye chart, then the other eye is shielded by lifting a shielding cover with a hand or a hand, when one eye is shielded by the existing hand, a tester possibly uses the shielded glasses to see the eye chart through a gap of the hand, and the test result is inaccurate. When one eye is shielded by holding the shielding cover with hands, the child feels soreness if the time is too long, and particularly in pediatric examinations, the child does not want to hold the shielding cover and easily cries after the time is too long.

The first air pipes 9 and the second air pipes 14 correspond one to one.

A person stirs the moving frame 10 to enable the moving frame 10 to be far away from the mirror frame 12, the moving frame 10 moves to drive the first air pipe 9 to move along the length direction of the second air pipe 14 until the first air hole 15 is communicated with the second air hole 16, and the moving frame 10 stops being stired. When the first air hole 15 and the second air hole 16 are communicated, the second air hole 16 is communicated with the clip flow passage 13, so that the air bag 8 is communicated with the clip flow passage 13 through the first air pipe 9.

When the air bag 8 is inflated, the moving frame 10 is firstly pulled to make the moving frame 10 far away from the mirror frame 12, and the first air pipe 9 moves along the length direction of the second air pipe 14 until the first air hole 15 and the second air hole 16 are communicated, so that the air bag 8 is communicated with the clip-shaped flow passage 13.

The air tap of the inflator is then inserted into the air port 24 to inflate the air bag 8. The gas enters from the gas port 24 and flows to the second opening 23 along the second channel 21, the gas pushes the valve plate 27 arranged at the first opening 22 and the second opening 23 away, the valve plate 27 rotates to compress the spring 26, after the valve plate 27 is pushed away, the gas flowing out of the second opening 23 flows into the first channel 20 from the first opening 22, then flows into the two return flow channels 13, flows into the first gas pipe 9 through the second gas hole 16 and the first gas hole 15, and finally flows into the airbag 8, so that the airbag 8 is fully inflated and expanded.

After the inflation is finished, the air nozzle of the inflator is pulled out, the spring 26 pushes the valve plate 27 to rotate under the restoring force of the spring 26, the valve plate 27 is inclined again to cover the first opening 22 and the second opening 23, and the valve plate 27 seals the first opening 22 and the second opening 23.

Then the tester wears the glasses for treatment, the moving frame 10 is pressed towards the side of the eyes of the tester, so that the air bag 8 is pressed around the eyes, in the pressing process, the air in the air bag 8 is pressed out of the air bag 8, the amount of the pressed air of different air bags 8 is different due to different shapes around the eyes, the air in the air bag 8 is pressed out of the air bag 8, then flows to the return-type flow channel 13 through the first air hole 15 and the second air hole 16, then flows to the first opening 22 along the first channel 20, the air pushes away the valve plate 27 arranged at the first opening 22 and the second opening 23, the valve plate 27 rotates the compression spring 26, after the valve plate 27 is pushed away, the air flowing out from the first opening 22 flows into the second channel 21 from the second opening 23, and finally flows out to the outside atmosphere from the air port 24.

The spring 26 is used to press the valve plate 27 so that the valve plate 27 cannot rotate without being pushed by the gas flowing out from the first opening 22 or the second opening 23.

After the air bag 8 is pressed around the eyes so that the air bag 8 is attached around the eyes, the mirror frame 12 is pressed towards the movable frame 10 side so that the movable frame 10 and the mirror frame 12 are attached together, the first air hole 15 and the second air hole 16 are not communicated in a staggered mode, and the air in the air bag 8 cannot flow out of the clip-shaped flow passage 13. Through the operation, the amount of gas stored in different air bags 8 is different, so that the swelling sizes of the air bags 8 are different, and the light shield 7 is matched with the shape around the eyes of a tester to achieve a better shielding effect.

To the tester of difference, only need repeat above-mentioned operation, stir to remove frame 10 and make and remove frame 10 and keep away from picture frame 12, then aerify gasbag 8, aerify the back that finishes, will remove frame 10 again and press towards tester eye one side, press the back that finishes, press picture frame 12 again and make and remove frame 10 and picture frame 12 laminating together can.

Further in detail, a limiting block 17 is arranged on the outer side of the first air pipe 9, a limiting groove 18 is formed in the inner side wall of the second air pipe 14, the limiting groove 18 is formed in the length direction of the second air pipe 14, the moving frame 10 moves to drive the first air pipe 9 to move, so that the limiting block 17 moves along the length direction of the limiting groove 18, and the limiting groove 18 is used for being matched with the limiting block 17 to limit the moving distance of the first air pipe 9.

When the first air pipe 9 moves along the length direction of the second air pipe 14, the stopper 17 moves along the length direction of the stopper groove 18, and when the first air hole 15 and the second air hole 16 are aligned, the stopper 17 moves to the end of the stopper groove 18. When the limiting block 17 moves to the position that the end part of the limiting groove 18 is blocked by the side wall of the limiting groove 18, the first air hole 15 is aligned with the second air hole 16, and the arrangement limits the moving distance of the first air pipe 9 so that the first air hole 15 can be aligned with the second air hole 16.
