Position-adjustable vision testing auxiliary frame for medical treatment

Abstract

The invention discloses a position-adjustable vision testing auxiliary frame for medical treatment. The position-adjustable vision testing auxiliary frame comprises a main base plate. Two ends of the top surface of the main base plate are fixedly provided with vertical supporting plates. Two ends of a transverse screw are hinged to the two vertical supporting plates. An outer side wall of one vertical supporting plate is fixedly provided with an adjusting motor. An output shaft of the adjusting motor is a spline shaft. The spline shaft is inserted and sleeved in a spline hole in one end of the transverse screw. A movable block is screwed in the transverse screw. The top surface of the movable block is fixedly provided with a connecting plate. The middle of the top surface of the connecting plate is fixedly provided with a supporting frame. The bottom of the top plate of the supporting frame is fixedly provided with a lifting motor. An output shaft of the lifting motor passes through the top plate of the supporting frame and is screwed with a vertical threaded sleeve. The top of the vertical threaded sleeve is fixedly provided with a connection transverse bar. An end portion of the connection transverse bar is fixedly provided with an eyeshield baffle plate. The bottom of the movable block is fixedly provided with a self-lubricating block. The position-adjustable vision testing auxiliary frame can be disposed on tables and chairs and fixed by bolts, and can also be automatically lifted to shield eyes without hand holding.

Description

Technical field: [0001] The invention relates to the technical field of medical equipment, in particular to a position-adjustable medical vision detection auxiliary frame. Background technique: [0002] When the existing ophthalmology department conducts manual visual acuity detection, a person generally holds a baffle with one hand to block one eye, and uses the other eye to look at the symbols for detection, but it is very troublesome to hold the baffle with one hand, and when testing , the eyes at the occluded place are often pressed very tightly, so that when detecting the previously occluded eyes, the eyes will have a sense of blur, which will affect the detection effect. Invention content: [0003] The purpose of the present invention is to address the deficiencies of the prior art, and provide a position-adjustable medical vision detection auxiliary frame, which can be placed on tables and chairs and fixed by bolts, which can be automatically lifted to block the eye...
