Beneficial effect
The adjustable sight test means of a kind of ophtalmic treatments of the invention, its working principle is that: it is detected when to continue force
When, allow ophthalmic patient that eyes are directed at window from the back side of device, its forehead can encounter rubber pad and carry out to sensor block at this time
Pressing, sensor block move forward, and drive band tooth top bar mobile, drive first by the engaging tooth that its upper surface is equipped with tooth top bar
Gear drives second gear in rotating clockwise in rotating clockwise, by the first driving belt, and second gear can pass through at this time
It drives band tooth slide bar to translate backward with the engaging tooth that tooth slide bar lower surface is equipped with, while l-shaped rod translation being driven to pull motor switch
Button drives the rotation of power spin bar in inclined downward backward, starting motor, and driving third gear by change gear is in up time
Needle rotation, then drive the 4th gear in rotating clockwise by the second driving belt, because the 4th gear is set to folding rotation pipe sleeve
Inside, therefore opening and closing rotation pipe sleeve to hang mobile jib lower end is the center of circle in rotating clockwise, and protective cover is driven to open upwards;Work as protection
Lid turns to when tilting in forward upward, and gag lever post can apply pressure to contact block and be recessed inwards, and contact block pushes mandril rearward
It is mobile, rope is pullled, motor switch button is turned back into original state, closes motor, protective cover can carry out eyesight survey in shape is opened
Examination;After the completion of test, the forehead of ophthalmic patient leaves sensor block, and sensor block loses pressure, returns under the action of the first spring
Bullet will retract original state with tooth top bar, similarly be driven first gear, second gear revolution, the work of second gear is lost with tooth slide bar
Firmly, it moves forward under the action of second spring, l-shaped rod returns to motor switch button front lower place at this time, convenient for being again started up;Most rear defence
Protecting cover rotates around folding and closes under pipe sleeve automatic slowly, cover the adjustable eyesight testing of ophtalmic treatments under self gravitation effect
