Description

Technical Field

[0001] The utility model relates to a binocular rotating mirror mechanism, belonging to the technical field of optometry instruments. Background Art

[0002] In the prior art, for example, the utility model application No. 201820372678.6 discloses a test disc and a comprehensive ophthalmometer. To address the problem of difficulty in reading the scale during test in a dark room with relatively dim lighting, which significantly affects the accuracy of the test, the side of the test disc facing the operator is an operating surface, and a light-emitting device is provided on the operating surface to provide a light source for illumination. When using the test disc provided by the utility model for test in a dark room with relatively dim lighting, the operator can turn on the light-emitting device to provide appropriate lighting conditions, making it easier for the operator to clearly read the scale on the test disc, thereby improving the accuracy of the test.

[0003] Similar to the above application, there are still some deficiencies:

[0004] During the optometry operation, the position of the lens disc needs to be adjusted and rotated manually, which is inconvenient and affects the optometry speed. In addition, when adjusting the distance between the lens discs, the distance is adjusted by using a screw to control the sliding of a slider. There will be a certain amount of wear between the screw and the slider, which will affect the adjustment accuracy after long-term use.

[0005] Therefore, a binocular rotating mirror mechanism is designed to optimize the above problems. Utility Model Content

[0024] Overall working principle: During the eye examination process, the distance adjustment component 3 is used to control the two groups of sliding seats 2 to slide along the length direction of the pupil distance guide rail 1, and then the distance between the two groups of lens disks 6 is adjusted according to the pupil distance. During the inspection, the stepper motor 4 is started to rotate the rotating disk 5 to rotate and adjust the position of the lens disk 6. No manual operation is required, which is practical and convenient, and improves the speed of eye examination.

[0025] In this embodiment, a transfer block is fixed at the middle position of the back side of the rotating disk 5 , the transfer block is sleeved on the output shaft of the stepping motor 4 , and the outer side of the transfer block is fixedly connected to the output shaft by screws.

[0026] Partial working principle: The output end of the stepper motor 4 is fixedly connected to the rotating disk 5 through the adapter block, ensuring that the stepper motor 4 drives the rotating disk 5 to rotate stably.

[0027] In this embodiment, the sliding seat 2 includes a support plate 12, a shaft 13, a roller 14 and a sliding lining 15. The support plate 12 is attached to the outer side of the pupillary distance guide rail 1. The back of the support plate 12 and the top and bottom of the pupillary distance guide rail 1 are fixed with a shaft 13. The middle position of the shaft 13 is rotatably installed with a roller 14. The roller 14 rolls on the outer side of the pupillary distance guide rail 1. The sliding lining 15 that is attached to the back of the pupillary distance guide rail 1 is fixed between the ends of the shaft 13, and the stepper motor 4 is fixed to the top of the support plate 12.

[0028] Local working principle: When the sliding seat 2 moves on the interpupillary distance guide rail 1, the support plate 12 is attached to the outer surface of the interpupillary distance guide rail 1, and the sliding lining 15 is attached to the back of the interpupillary distance guide rail 1. In addition, the roller 14 is located at the top and bottom of the interpupillary distance guide rail 1 to ensure that it is stably clamped on the interpupillary distance guide rail 1, thereby ensuring stable movement of the sliding seat 2.

[0029] In this embodiment, the spacing adjustment assembly 3 includes a connecting plate 7, a fixed plate 8, a movable motor 9, a gear 10 and a rack 11. The connecting plate 7 is fixed at the top and bottom of the interpupillary distance guide rail 1. A fixed plate 8 is fixed between the two sets of connecting plates 7.

The rack 11 slides along the length direction of the interpupillary distance guide rail 1, and the ends of the two sets of racks 11 away from the gear 10 are respectively fixedly connected to the sliding lining 15.

[0030] Local working principle: When controlling the movement of the sliding seat 2, start the moving motor 9 to drive the gear 10 to rotate. The rotation of the gear 10 simultaneously drives the two racks 11 to move laterally, pulling the sliding seat 2, and controlling the two groups of sliding seats 2 to move simultaneously on the pupil distance guide rail 1.

[0031] In this embodiment, a stopper for limiting the moving distance of the sliding lining 15 is fixed to one end of the back of the interpupillary distance guide rail 1 by means of bolts.

[0032] Partial working principle: During the movement of the sliding seat 2, the setting of the block can limit the moving distance of the sliding seat 2 to avoid separation between the sliding seat 2 and the pupil distance guide rail 1.

[0033] In this embodiment, copper pillars are vertically fixed at the four corners of the outer side of the fixing plate 8 , and circuit linings are fixed to the ends of the copper pillars, and the circuit linings and the fixing plate 8 are parallel to each other.
