[0021] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0022] Eye examinations are important in many ways. Slit lamp examinations can observe lesions in the eyelids, conjunctiva, cornea, lens and other parts. Fundus examinations can detect abnormalities in the retina, optic nerve and other parts. Eye examinations can detect potential problems before the disease has obvious symptoms, so that early intervention and treatment can be carried out to avoid further deterioration of the disease. Regular eye examinations help to establish eye health records for individuals and record eye examination data at different stages. By analyzing and comparing these data, we can understand the changing trends of eye health and provide a basis for personalized eye care and disease prevention.

When conducting an inspection, the front end of the rubber stretching piece 7 contacts the eye socket and the inclined surface of the rubber stretching piece 7 is used to stretch the eyelid outward. At the same time, after the inspection is completed, a new rubber stretching piece 7 is replaced to effectively reduce the disinfection time, and solve the problem that the stretching piece needs to be repeatedly disinfected during the inspection process, resulting in low inspection efficiency. An inspection mechanism is provided in the inspection shell 1, hinged tightening mechanisms are provided on both sides of the inspection shell 1, and a ventilation mechanism is provided above the inspection shell 1.

[0024] The inspection mechanism includes an inspection hole 9, an inspection camera 10, an arc-shaped rubber pad 11 and a rubber nose pad 12. The inspection holes 9 are symmetrically opened on the arc-shaped plate 2, and the inspection holes 9 correspond to the rubber stretching piece 7. The inspection camera 10 is symmetrically fixed on the rear side of the inspection shell 1. The front side of the inspection shell 1 is open and surrounded by an arc-shaped rubber pad 11. A rubber nose pad 12 is fixed on the upper middle of the front side of the inspection shell 1. When conducting an inspection, the inspection shell 1 is worn in front of the eyes, and the arc-shaped rubber pad 11 fits and supports the face, and the rubber nose pad 12 fits and supports the patient's nose bridge. When conducting an inspection, the inspection camera 10 takes a picture of the eyes through the inspection hole 9.

[0025] The articulated locking mechanism comprises an articulated seat 13, a tightening belt 14, a rear fixing belt 15, a tightening bin 16, a tightening disk 17, a tightening groove 18 and a locking mechanism. The articulated seats 13 are symmetrically fixed on both sides of the inspection housing 1. A tightening belt 14 is hingedly connected on the articulated seat 13. A rear fixing belt 15 is sleeved in the middle of the tightening belt 14. A tightening bin 16 is fixed on the middle front side of the rear fixing belt 15. A tightening disk 17 is rotatably arranged in the tightening bin 16. A tightening groove 18 is opened around the edge of the tightening disk 17. A locking mechanism is arranged on the tightening disk 17. An opening is passed horizontally through the middle of the tightening disk 17, and the tightening belt 14 passes through the middle of the tightening disk 17. When the inspection shell 1 is worn on the user's head, the rear fixing belt 15 is put on the rear part of the user's head, and the tightening disk 17 is rotated according to the size of the user's head to pull the tightening belt 14 along the tightening groove 18 to wrap around the tightening disk 17 for tightening.

[0026] The locking mechanism includes a locking hole 19, a locking pin 20 and a limiting ring 21. The locking holes 19 are symmetrically opened on the tightening disk 17, and the locking pins 20 are symmetrically inserted on the tightening bin 16. The locking holes 19 correspond to the positions of the locking pins 20. A limiting ring 21 is fixed in the middle of the locking pin 20. When the tightening disk 17 is adjusted to be tightened to an appropriate degree, the end of the locking pin 20 is pushed into the locking hole 19 for locking. At the same time, the limiting ring 21 effectively prevents the locking pin 20 from slipping out of the tightening bin 16.

[0027] The ventilation mechanism includes a ventilation bin 22, a rotating cover 23, a first ventilation hole 24 and a second ventilation hole 25. The ventilation bin 22 is symmetrically fixed above the inspection shell 1, and a rotating cover 23 is rotatably provided above the ventilation bin 22. The first ventilation hole 24 is symmetrically opened on the top of the ventilation bin 22, and the second ventilation hole 25 is symmetrically opened on the front and back of the rotating cover 23. The rotating cover 23 is sleeved on the outside of the ventilation bin 22 and rotates. The positions of the first ventilation hole 24 and the second ventilation hole 25 correspond to each other. When the inspection shell 1 is used for a long time and water vapor may be generated in the inspection shell 1 to affect the inspection effect, the rotating cover 23 is rotated to adjust the size of the staggered gap between the first ventilation hole 24 and the second ventilation hole 25 for ventilation.

[0028] When the multi-purpose ophthalmic examination device is used for examination, the examination shell is covered on the user's face, and the rear fixing belt is put on the back of the user's head. The tightening disk is rotated according to the size of the user's head and the tightening belt is pulled for adjustment, and the examination shell is tightened and fixed on the head, and the locking pin is pushed to be inserted into the locking hole for locking. The rubber expansion piece contacts and expands the area around the user's eyes for convenient inspection. When the inspection is carried out, the inspection camera shoots the eyeball through the inspection hole for inspection. After the inspection is completed, the tightening disk is loosened and the inspection shell is removed. The rubber expansion piece is pulled to release the limit between the arc limit strip and the limit groove, and the shell is removed for replacement. The clean rubber expansion piece and the replacement piece are stuck in the groove for convenient and quick replacement. When ventilation is needed, the rotating cover is twisted to adjust the gap between the first air hole and the second air hole for ventilation to prevent water vapor from affecting the inspection.
