Description

Technical Field

[0001] This utility model relates to the field of fundus camera technology, and in particular to a fundus camera with an adjustable chin rest. Background Technology

[0002] A fundus camera is a medical device used to capture images of the back of the eye. It is of great significance for the diagnosis, monitoring and treatment of eye diseases. The fundus camera emits light into the eye. After passing through refractive media such as the cornea and lens, the light is focused on the retina at the back of the eye. The light reflected from the retina returns along the same path and passes through the camera's optical system, finally forming an image on the image sensor, thus obtaining a clear image of the fundus.

[0003] Currently available fundus cameras have relatively fixed chin rests, which are time-consuming and laborious to adjust, preventing doctors from making quick diagnoses and reducing the efficiency of their medical examinations. This diminishes the usability of the product. To address these issues, we propose a fundus camera with an adjustable chin rest. Utility Model Content

[0004] The purpose of this invention is to provide a fundus camera with an adjustable chin rest to solve the problems mentioned in the background art.

[0025] The working principle of this utility model is as follows:

[0026] When using this device, the operator first uses the mounting plate 18 and mounting holes 19 to fix the base 1 to the desktop and connects the device to an external power source. Then, the operator adjusts the height and front-back position of the chin rest body 13 according to actual needs. When adjusting the height and front-back position, the operator uses the controller to start the electric push rod 12, which drives the chin rest body 13 to move up and down. At the same time, the operator uses the controller to start the forward and reverse motor 6, which drives the threaded rod 8 to rotate. The rotation of the threaded rod 8 causes the threaded block 9 to drive the connecting block 10 and the sliding plate 11 to slide back and forth. Thus, the sliding plate 11 drives the electric push rod 12 and the chin rest body 13 to slide back and forth to adjust their positions. The above is the complete operation process of this device.
