Description

Technical Field

[0001] The utility model relates to the technical field of retinoscopes, in particular to a retinoscope capable of being viewed by multiple persons. Background Art

[0002] The retinoscope uses its lighting system to illuminate the inside of the eyeball. The light is reflected from the retina and changes after passing through the refractive component of the eyeball. The refractive state of the eyeball can be determined by examining the changes in the reflected light. The light source of the retinoscope is usually a small electric bead that emits light, which can be point-shaped or strip-shaped. The light emitted by the light source is converged by a condenser to form parallel light or point-shaped light when projected. The propagation direction of the light is changed by a reflector so that the light can be projected from a specific peephole of the retinoscope. The light converged by the condenser is refracted 90 degrees by a projection mirror so that it can be projected to the eye being examined.

The camera 5 is a prior art, which has a Bluetooth transmission function and can transmit the captured image to the display screen via Bluetooth. No further elaboration is made here. Through the setting of the conical eyepiece 4, the examiner can conveniently place the glasses near the eyepiece 4 for inspection, and the camera 5 can also be positioned.

[0021] In this embodiment, the splicing component includes a socket 8, a rod 9, a sliding rod 7 and a sliding component. The two sockets 8 are respectively opened on the front and rear sides of the handle 1. The two rods 9 are respectively detachably inserted in the inner cavities of the two sockets 8. The two sliding rods 7 are respectively fixedly connected to the ends of the two rods 9 that are away from each other. The sliding component is arranged in the inner cavity of the casing 6. The front and rear sides of the bottom end of the sliding component respectively extend to the front and rear sides of the bottom end of the casing 6 and are respectively fixedly connected to the top ends of the two sliding rods 7. The two sliding rods 7 and the two rods 9 are inserted into the inner cavity of the socket 8 through the sliding component, and the camera 5 is fixed under the joint action of the rod 9 and the socket 8.

[0022] In this embodiment, the sliding assembly includes a screw rod 10, a slider 11, a slideway 12, a moving rod 13, a limit assembly and a positioning assembly. One end of the screw rod 10 is rotatably connected to the rear side of the inner cavity of the casing 6 through a bearing, and the other end of the screw rod 10 extends to the front end of the casing 6 and is connected to the positioning assembly. The two sliders 11 are respectively screwed to the front and rear sides of the outer wall of the screw rod 10. The slideway 12 is opened at the bottom end of the casing 6. The two moving rods 13 can be slidably embedded in the inner cavity of the slideway 12. One end of the two moving rods 13 is respectively fixedly connected to the top of the two sliding rods 7, and the other end of the two moving rods 13 is respectively fixedly connected to the bottom ends of the two sliders 11. The positioning assembly is arranged at the top of the inner cavity of the casing 6, and the rotating cylinder 16 is rotated so that the rotating cylinder 16 drives the screw rod 10 to rotate under the limiting action of the connecting groove 19 and the connecting block 20. Since the threads on the front and rear sides of the outer wall of the screw rod 10 are relatively arranged, when the screw rod 10 rotates, the two sliders 11 can slide toward the middle of the screw rod 10 at the same time under the limiting action of the limiting groove 14 and the limiting block 15, so that the two moving rods 13 respectively drive the two sliding rods 7 and the two plug rods 9 to slide toward the middle of the bottom end of the casing 6 at the same time, so that the two plug rods 9 are respectively inserted into the inner cavities of the two plug holes 8, and the camera 5 is fixed under the joint action of the plug rods 9 and the plug hole 8.

[0023] In this embodiment, the threads on the front and rear sides of the outer wall of the screw rod 10 are arranged relative to each other, so that when the screw rod 10 rotates, the front and rear sides of its outer wall generate relative thread rotation forces, so that the two sliders 11 slide relatively at the same time under the limiting action of the limiting groove 14 and the limiting block 15.

[0024] In this embodiment, the limit assembly includes a limit groove 14 and a limit block 15. The limit groove 14 is opened at the top of the inner cavity of the casing 6. The two limit blocks 15 can be slidably embedded in the inner cavity of the limit groove 14 and fixedly connected to the outer walls of the two sliders 11. The joint action between the limit groove 14 and the limit block 15 can prevent the slider 11 from rotating with the screw rod 10 when the screw rod 10 rotates, thereby improving the stability of the sliding assembly when in use.

[0025] In this embodiment, the positioning assembly includes a rotating cylinder 16, a limit plate 17, a spring 18, a connecting assembly, a fixing hole 21 and a fixing rod 22. The rotating cylinder 16 is sleeved on the outer wall of the screw rod 10, the limit plate 17 is slidably embedded in the inner cavity of the rotating cylinder 16 and is fixedly connected to the front end of the screw rod 10, the spring 18 is sleeved on the outer wall of the screw rod 10, and the two connecting assemblies are respectively arranged on the upper and lower sides of the inner wall of the rotating cylinder 16 and are fixedly connected to the outer wall circumference of the limit plate 17. A plurality of fixing holes 21 are equidistantly opened along the axle box at the front end of the housing 6, and the fixing rod 22 is detachably inserted into the inner cavity of one of the fixing holes 21 and is fixedly connected to the rear end of the rotating cylinder 16. The ends are fixedly connected, the inner cavity of the fixing hole 21 is matched with the outer wall of the fixing rod 22 and both are tapered, and the rotating cylinder 16 is pulled forward so that the rotating cylinder 16 and the limiting plate 17 cooperate to squeeze the spring 18, thereby causing the spring 18 to produce corresponding elastic deformation and generate corresponding elastic force, so that the fixing rod 22 is separated from the inner cavity of the fixing hole 21. After the insertion rod 9 is inserted into the inner cavity of the insertion hole 8, the rotating cylinder 16 is released. Under the action of the elastic force of the spring 18, the fixing rod 22 on the rear side of the rotating cylinder 16 can be inserted into the inner cavity of the corresponding fixing hole 21, thereby fixing the angle of the screw rod 10 to prevent the screw rod 10 from rotating and causing the insertion rod 9 to be separated from the insertion hole 8.

[0026] In this embodiment, the connecting assembly includes a connecting groove 19 and a connecting block 20. The connecting groove 19 is opened on the inner wall of the rotating cylinder 16. The connecting block 20 can be slidably embedded in the inner cavity of the connecting groove 19 and fixedly connected to the outer wall circumference of the limiting plate 17. Through the setting of the connecting block 20 and the connecting groove 19, the screw rod 10 can be driven to rotate when the rotating cylinder 16 rotates.

[0027] The use method and advantages of the utility model: When in use, the working process is as follows:

[0028] When installing the camera 5, the input end of the camera 5 is inserted into the inner cavity of the eyepiece 4. At this time, the insertion rod 9 can be aligned with the insertion hole 8, and the rotating cylinder 16 can be pulled forward so that the rotating cylinder 16 and the limiting plate 17 cooperate to squeeze the spring 18, thereby causing the spring 18 to produce corresponding elastic deformation and generate corresponding elastic force, so that the fixing rod 22 is separated from the inner cavity of the fixing hole 21. At this time, the rotating cylinder 16 is rotated so that the rotating cylinder 16 drives the screw rod 10 to rotate under the limiting action of the connecting groove 19 and the connecting block 20. Since the threads on the front and rear sides of the outer wall of the screw rod 10 are relatively arranged, when the screw rod 10 rotates, the two sliders 11 can slide toward the middle of the screw rod 10 at the same time under the limiting action of the limiting groove 14 and the limiting block 15, so that the two moving rods 13 respectively drive the two sliding rods 7 and the two insertion rods 9 to slide toward the middle of the bottom end of the casing 6 at the same time. The two plug rods 9 are moved so that the two plug rods 9 are respectively inserted into the inner cavities of the two sockets 8, and the camera 5 is fixed under the joint action of the plug rod 9 and the socket 8. At this time, the rotating cylinder 16 is loosened, and the fixing rod 22 on the rear side of the rotating cylinder 16 can be inserted into the inner cavity of the corresponding fixing hole 21 under the elastic force of the spring 18, so that the angle of the screw rod 10 can be fixed to prevent the screw rod 10 from rotating and causing the plug rod 9 to disengage from the socket 8. The image in the eyepiece 4 can be recorded by the camera 5 and the image can be transmitted to the display screen through its own Bluetooth device for display on the display screen, so that multiple people can view it at the same time, which solves the problem that the retinoscope in the prior art can only be viewed by one doctor during actual use, and when multiple people need to view it, the doctor needs to be changed multiple times to use the retinoscope to complete it, and the operation is very cumbersome and complicated.
