Abstract

The invention discloses an eyeball refractive change demonstrator. The demonstrator comprises a supporting seat, wherein a horizontally arranged groove strip is fixed to the outer wall of one side ofthe top end of the supporting seat through a bolt; a first sliding block and a second sliding block sleeve the outer wall of the groove strip; a vertically arranged telescopic adjusting rod is fixed to the middle position of the outer wall of the top end of the first sliding block through a bolt; an arc-shaped supporting block is fixed to the top end of the telescopic adjusting rod through a bolt;a cornea simulation block is clamped with the inner wall of the arc-shaped supporting block; a vertically arranged aqueous humor simulation plate is clamped with the top end of the second sliding block; and a first arc-shaped supporting piece is fixed to the outer wall, close to the groove strip, of the top end of the supporting seat. The demonstrator has the advantages that adjustment is convenient, operation is simple, the demonstrator can be finely adjusted, a better demonstration effect can be achieved, the demonstrator can be adjusted according to the condition of a demonstration desktop, the horizontal arrangement of the device is ensured, the speed is fast, the precision is high, the control is easy, and the smooth completion of the demonstration operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of eyeball demonstrators, in particular to an eyeball diopter change demonstrator. Background technique [0002] There are many reasons for myopia and presbyopia in the human eye. One of the important reasons is that the adjustment function of the lens is not normal. A sharp image is formed on the retina. However, the eyes are hidden in the head, and its adjustment to light can hardly be seen intuitively. It is difficult to introduce it when teaching or explaining the refractive state of the human eye. Currently on the market, there are model eyes that use liquid extrusion to simulate the change of the lens to explain the refractive state, but this lens change is realized by squeezing the liquid in the needle tube, which is slow and difficult to control. [0003] After retrieval, the Chinese patent authorization number is the patent of CN206312483U, which discloses a teaching aid for simulating eyeball ima...
