Problems solved by technology

[0002] When a doctor is doing a physical examination for a patient, the vision test for both eyes generally uses a hand-held mask to block one eye and test the vision of the other eye. Although this traditional detection device is simple, it must be manually held in practice. If the support is not standardized, it will affect the detection effect, which is troublesome to use and cannot ensure the accuracy of detection

Abstract

The invention discloses a vision examining device which comprises a support, a gear assembly and a blocking assembly. The blocking assembly comprises a first blocking plate and a second blocking plate. The first blocking plate and the second blocking plate are located on the two sides of the support and installed on two rotating rods of the support respectively. The gear assembly comprises a first gear, a second gear and a third gear. The first gear, the second gear and the third gear are bevel gears. The rotating rods can rotate together with the first blocking plate and the second blocking plate, the first gear is installed at the tail end of the rotating rod connected with the first blocking plate, the second gear is installed at the tail end of the rotating rod connected with the second blocking plate, and the first gear and the second gear are simultaneously meshed with the third gear.

Description

Technical field: [0001] The invention relates to the technical field of medical appliances, and more specifically relates to a vision inspection device. Background technique: [0002] When a doctor is doing a physical examination for a patient, the vision test for both eyes generally uses a hand-held mask to block one eye and test the vision of the other eye. Although this traditional detection device is simple, it must be manually held in practice. If the support is not standardized, it will affect the detection effect, which is troublesome to use and cannot ensure the accuracy of detection. Invention content: [0003] The purpose of the present invention is to provide a vision inspection device for the deficiencies of the prior art, which is convenient to wear and use to cover the single eye to achieve vision detection and ensure the accuracy of the inspection. [0004] To achieve the above object, the technical scheme adopted in the present invention is as follows: ...
