Intelligent vision testing system

Abstract

The invention discloses an intelligent vision testing system in the technical field of vision testing, and the system comprises a seat; a support frame is fixedly connected to a right handle of the seat, a motor is fixedly connected to the top of the support frame, and a first base is fixedly connected to the top of the support frame; the first base is rotatably connected with a lead screw fixedly connected with an output shaft of the motor, the top of the supporting frame is slidably connected with a first moving seat and a second moving seat, a table is placed right in front of the seat, and a liquid crystal visual chart used for detecting vision is placed at the top of the table; brushes are arranged, along with leftward movement of a first moving seat, a second gear is matched with a conveying belt to drive a second rotating shaft and a third rotating shaft to synchronously rotate, and the second rotating shaft and the third rotating shaft drive respective brushes to rotate, so the two surfaces, making contact with customers, of the shielding plate are cleaned, the cleanliness of the shielding plate is ensured, and the cross infection is avoided.

Description

technical field [0001] The invention relates to the technical field of vision testing, in particular to an intelligent vision testing system. Background technique [0002] Visual acuity is generally divided into two categories: distance vision and near vision. In my country, the standard logarithmic vision chart is mainly used. First, cover one eye, and identify the direction of the "E" gap from top to bottom with one eye until it cannot be recognized, and record it. Can. [0003] The prior art discloses an invention patent about an intelligent vision testing system. The Chinese patent application number of the invention patent is 200680031677.5, which discloses that the automatic vision tester includes: a pair of left and right lens accommodation units each with a test window, the first a lens disk equipped with a viewing hole and a plurality of optical elements and placed in each lens accommodating unit at a position closer to the subject's eyes, and a second lens disk equ...

Problems solved by technology

[0006] The purpose of the present invention is to provide a kind of intelligent eyesight testing system, to solve the problem in the background technology mentioned above, when carrying out the vision test, it is necessary to cover one eye with a board to perform the vision test, and the boards used to cover the eyes are being used by many people. After people use it repeatedly, it will cause a lot of bacteria and stains on the board. If you continue to use it, it will easily cause cross-infection and the risk of spreading pink eye disease.
