Transmission.The first gear and second gear can be rotated around cylinder, and engaging between first gear and second gear makes
It obtains and is rotated synchronously between two adjusting handles, and realized due to the self-friction power of gear and position self-locking function.
Further, the second frame body side is provided with light source base, and laser light source is arranged inside, and can emit specific wavelength
Laser come out by entire lens barrel and by lens lighting.
Preferably, the light source base include emit laser laser generator, can launch wavelength range in 650-
The laser beam of 680nm and the lens for passing through lens barrel via lens barrel.
A kind of ophthalmic medical equipment, using a kind of any of the above-described interpupillary adjustment mechanism.
The beneficial effects of the utility model are, provide a kind of gear adjusting machine for adjusting spacing between lens barrel
Structure, so that the close of lens barrel or separation are realized in the movement that can do arc between lens barrel, and then the people for adjusting different interpupillary distances makes
Enter the optical path of eyes with adjusting when same equipment to realize optimal therapeutic effect.The utility model structure is simple, and
It can realize that lock-bit without increasing other positioning devices, is simplified by the engaging friction between gear regulating mechanism middle gear
Structure.
