[0002] The main observations on the eyes include whether there are congenital abnormalities of the eyelids, such as eyelid coloboma, narrow palpebral fissure, ptosis, etc. Eyelid skin abnormalities, abnormal eyelid position, abnormal eyelid margins and eyelashes, tear apparatus examination, etc. In order to observe the eyes more clearly, a slit observation lamp is generally required.

[0003] When observing the patient's eyes, not only does the position of the slit lamp need to be adjusted, but sometimes the patient is also required to cooperate with the doctor to move it. However, misunderstandings are easy to occur during communication, resulting in the patient's movement being too large, too small, or in the opposite direction, which requires secondary communication and affects the doctor's examination efficiency.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

The rotating component 1 is used to drive the sliding component 3 to adjust the angle, the driving component 2 is used to drive the sliding component 3 to slide up and down, the sliding component 3 is used to support the head of the examinee, and the observation component 4 is used to observe the eyes of the examinee.

[0030] First, the patient places his head on the sliding component 3 and faces the observation component 4. The doctor observes the patient's eyes through the observation component 4. During the observation process, if the patient's position needs to be adjusted, the doctor can rotate the rotating component 1, and the rotating component 1 drives the sliding component 3 to rotate, thereby changing the angle between the sliding component 3 and the observation component 4. The driving component 2 can drive the sliding component 3 to move up and down, changing the height between the sliding component 3 and the patient's eyes, so that the observation component 4 can more easily examine the patient on the sliding component 3 from different positions.

[0031] The utility model connects the rotating component 1 and the sliding component 3. When the patient needs to adjust the position, the doctor directly rotates the rotating component 1 to drive the sliding component 3 to rotate, and then drives the driving component 2 to drive the sliding component 3 to move up and down to adjust the height, so that the position of the sliding component 3 and the observation component 4 can cooperate with each other to adjust to the angle required by the doctor. The patient on the sliding component 3 only needs to cooperate with the doctor to twist it slightly, and the patient does not need to actively move, thereby avoiding the occurrence of time waste due to communication misunderstandings, which is conducive to improving the efficiency of the examination.

[0032] In one embodiment, for the above-mentioned rotating component 1, the rotating component 1 includes a circular plate 101, the internal rotation of the circular plate 101 is connected to a rotating plate 102, the bottom of the rotating plate 102 is fixedly connected to a rotating shaft 103, the outer surface of the rotating shaft 103 is fixedly connected to a first gear 104, the outer surface of the first gear 104 is meshed with a second gear 105, the second gear 105 is rotationally connected to the inside of the circular plate 101, and the outer surface of the second gear 105 is fixedly connected to a rotating table 106.

[0033] Rotate the rotating plate 102, the rotating plate 102 drives the rotating shaft 103 to rotate, the rotating shaft 103 drives the first gear 104 to rotate and mesh with the second gear 105, at this time the second gear 105 can drive the rotating table 106 to rotate, through the meshing of the first gear 104 and the second gear 105, the number of teeth of the first gear 104 is smaller than that of the second gear 105, the rotation amplitude of the second gear 105 and the rotating table 106 can be smaller, so that it is easier for the doctor to fine-tune the position of the rotating table 106.

[0034] In one embodiment, for the above-mentioned driving assembly 2, the driving assembly 2 includes a rotating handle 201, the end of the rotating handle 201 is fixedly connected to a rotating rod 202, the outer surface of the rotating rod 202 is fixedly connected to a first bevel gear 203, the outer surface of the first bevel gear 203 is meshed with a second bevel gear 204, the outer surface of the second bevel gear 204 is fixedly connected to a screw 205, and the rotating rod 202 is rotatably connected to the circular plate 101.

[0035] The handle 201 is rotated, and the handle 201 drives the rotating rod 202 and the first bevel gear 203 to rotate. The first bevel gear 203 drives the second bevel gear 204 and the screw 205 to rotate. Through the engagement of the first bevel gear 203 and the second bevel gear 204, the second bevel gear 204 and the screw 205 can be driven to rotate by rotating the rotating rod 202 sideways, which is convenient for rotating the rotating rod 202.

[0037] When the rotating table 106 rotates, the rotating table 106 drives the fixed rod 301 and the sliding plate 303 to rotate synchronously, thereby adjusting the angle of the sliding plate 303. When the screw rod 205 rotates, it drives the sliding plate 303 to move. The sliding plate 303 moves up and down along the sliding groove 302 on the fixed rod 301, thereby changing the height position of the sliding plate 303. When the patient puts his head on the sliding plate 303, the sliding plate 303 moves with the doctor's adjustment, so that the patient's position can better meet the doctor's requirements and improve the examination efficiency.

[0041] In one embodiment, for the rotating plate 102 , an anti-slip protrusion 6 is fixedly connected to the outer surface of the rotating plate 102 .

[0042] The bottom plate 5 is used to connect the base 401 and the circular plate 101 so that the two have integrity and are easy to carry and transport. The anti-slip protrusions 6 on the rotating plate 102 can increase the friction between the rotating plate 102 and the doctor's hand to avoid slipping and affecting the adjustment angle.

[0043] Through the above technical solution, 1. Through the connection between the rotating component 1 and the sliding component 3, when the patient needs to adjust the position, the doctor directly rotates the rotating component 1 to drive the sliding component 3 to rotate, and then drives the driving component 2 to drive the sliding component 3 to move up and down to adjust the height, so that the position of the sliding component 3 and the observation component 4 can cooperate with each other to adjust to the angle required by the doctor, and the patient on the sliding component 3 only needs to cooperate with the doctor to slightly twist, and the patient does not need to actively move, thereby avoiding the situation of wasting time due to communication misunderstanding, which is conducive to improving the inspection efficiency. 2. Through the connection between the rotating table 106 and the fixed rod 301, when the rotating plate 102 drives the rotating table 106 to rotate, the fixed rod 301 and the sliding plate 303 on the rotating table 106 rotate synchronously, and the rotating screw 205 can drive the sliding plate 303 to move up and down. After the patient puts his head on the sliding plate 303, when the doctor adjusts the position of the sliding plate 303, the patient only needs to be in a relaxed state and slightly change the position with the doctor's adjustment, thereby avoiding the situation that the patient's position cannot reach the doctor's ideal state due to communication misunderstanding, thereby affecting the inspection efficiency.
