Medical optometry mirror with clamping mechanism

Abstract

The invention provides a medical optometry mirror with a clamping mechanism. The mechanism is connected to the rear end part of an optometry mirror leg through a rotary shaft I; the mechanism comprises an arc-shaped bent part connected with the optometry mirror leg; the front end of the arc-shaped bent part is connected with the optometry mirror leg through the rotary shaft I, and the rear end of the arc-shaped bent part is connected with a hook-shaped clamping part through a rotary shaft II; grooves are uniformly formed in the periphery of the rotary shaft II; a V-shaped buckling part with a bulge at the bottom is arranged above the grooves; one end of the V-shaped buckling part is connected onto the arc-shaped bent part and a pawl is arranged at the other end of the V-shaped buckling part; and the pawl extends upwards to form a pushing part. The clamping mechanism is connected to the rear end part of the optometry mirror leg through the rotary shaft, and the clamping mechanism is clamped with ears through adjusting the fitness and tightness with the ears; a condition that the optometry mirror cannot be adapted to the ears of children, caused by the fact the size of the optometry mirror is large, is not caused; and meanwhile, the optometry mirror does not fall off when the children move without permission, a good optometry foundation is provided for accurately determining optometry degrees, and the mechanism has a simple structure and is convenient to adjust.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a medical spectacles with a clamping mechanism. Background technique [0002] There are more and more myopic patients, especially children. This group of glasses is still in the developmental stage. In addition to watching computers or mobile phones and other electrical appliances, their self-control is poor, and they cannot rest their eyes well or take other protection. Measures, after waiting for the vision loss, you need to go to the hospital for examination work. During this process, medical staff need to perform optometry on them, and find a reasonable degree by trying on the optometrist, but the general-purpose eyeglasses are too large to be suitable for children. According to the patient's request, after they put on this kind of prescription glasses, it is easy to fall off. Coupled with the disorder of children, it is difficult for medical staff to judge the reasonable deg...

Problems solved by technology

[0002] Now there are more and more myopia patients, especially children. The glasses of this group are still in the development stage. In addition, they have poor self-control when watching computers or mobile phones and other electrical appliances. They cannot rest their eyes well or take other protection. The measure is to go to the hospital for examination after the eyesight declines. During this process, the medical staff need to refract them and find a reasonable degree by trying on refraction glasses. However, the general spectacle glasses are too large to adapt to children. According to the patient's request, after they put on this kind of prescription glasses, they are easy to fall off. Coupled with the children's disorderly movement, it is difficult for medical staff to judge the reasonable prescription, which brings a lot of trouble to the subsequent configuration of glasses.
