Description
This utility model relates to a kind of correcting vision device, especially the myopia rehabilitation mirror of being made up of mirror holder, the movable eyeglass of fixing len.
Myopia sickness rate in vast teenager is very high.It is each patient's eager desire that the treatment myopia is recovered vision.Current, existing bathomorphic various instruments of treatment and device." open happy photopic vision try hard to keep strong mirror holder " of promoting that experiment centre produces as the Shenyang Drymotaenium miyoshianum (Mak.) Mak. juvenile of group company sight protectio instrument; its theory structure is; one fixed mirror and one is set on a box frame flexible mirror of regulating the vision effect is arranged; adopt electromagnetism adhesive mechanism to make flexible mirror folding back and forth, recover the effect of vision to reach the treatment myopia.But, because its volume is big, carry extremely inconveniently, can not resemble the common spectacles with using with wearing, bring certain trouble and inconvenience to therapist, and these device for mechanical drive mechanism vibrations are big, noise is big, influences therapist and treats bathomorphic effect.
Task of the present utility model provides a kind of myopia rehabilitation mirror, and it can resemble the common spectacles and be worn over the patient at the moment to light and flexible, treats continuously whenever and wherever possible, and can reduce noise, reduces mechanical shock.
For solving above-mentioned task, the solution that this utility model adopts is: before the mirror of common spectacles, be provided with one and can reach the flexible mirror that recovers the vision effect, a controller box that is made of miniature relay and control circuit element board is set on a mirror holder lower limb, the mechanical box of being made up of micromachine and drive mechanism thereof is set on another mirror holder lower limb, and by connecting rod connection flexible mirror, power supply is introduced from socket, by wire connection controller and micromachine, the folding of flexible mirror is finished in the forward and reverse rotation of controller control micromachine.
Above-mentioned drive mechanism connects a screw mandrel that is provided with traveling nut by the micromachine rotating shaft, and traveling nut connects connecting rod one termination, and another termination of connecting rod connects flexible mirror.
Certainly, above-mentioned drive mechanism also can be changed system into fan type gear to the traveling nut on the screw mandrel, and screw mandrel is matched with sector gear, connects fan type gear and flexible mirror respectively with the two ends of connecting rod.
After making the flexible mirror folding arranged a suitable time of staying, the folding suo loco can be provided with limit switch, and limit switch is serially connected on the positive-negative power loop of micromachine in the relevant position, two ends of traveling nut or fan type gear stroke.
Owing to adopt micromachine in the above-mentioned solution, miniature relay and when simple basis set in bulk control circuit and external power supply can make rehabilitation mirror compact conformation, volume is small and exquisite, can be worn on the patient's eye very easily and treat whenever and wherever possible, and mechanical shock is little, noise is little in therapeutic process, helps improving therapeutic effect.
Below in conjunction with drawings and Examples this utility model is described in further detail.
Fig. 1 is power supply of the present utility model and controller circuitry schematic diagram.
Fig. 2 is a contour structures sketch map of the present utility model.
Fig. 3 is a controller box cutaway view of the present utility model.
Fig. 4 is a drive mechanism sketch map of the present utility model.
Fig. 5 is the drive mechanism sketch map of another embodiment of the present utility model.
In the circuit theory diagrams shown in Figure 1, the controller circuit element plate 7 that relay J and control circuit thereof constitute, be installed in the controller box 4 of rehabilitation mirror shown in Figure 2, micromachine M and drive mechanism 10,11,15,12 thereof are installed in the mechanical box 5, power supply adopts external power supply, is introduced by the socket on the lead slave controller box 48.
Drive mechanism in the mechanical box shown in Figure 4 is made up of micromachine 9, screw mandrel 10, traveling nut 11, connecting rod 12.Screw mandrel 10 1 ends are socketed on the turning cylinder of micromachine 9, and another termination then leans on the steady pin on the box shell 13, rock to prevent screw mandrel 10.Traveling nut 11 on the screw mandrel 10 can move forward and backward with screw mandrel 10 forward and reverse rotations, and connecting rod 12 1 terminations connect traveling nut 11, and another termination of connecting rod 12 connects flexible mirror 3.Relevant position at traveling nut 11 stroke two ends is provided with limit switch 14, and limit switch 14 is subjected to traveling nut 11 controls.
In the driver composition shown in Figure 5, then the traveling nut on the screw mandrel 10 11 is changed system into sector gear 15, connecting rod 12 two ends connect sector gear 15 and flexible mirror 3 respectively.Sector gear 15 advance to high-order and low level the relevant position, limit switch 14 is set, and controlled by sector gear 15.
Two limit switch K14 are serially connected in the positive-negative power loop of micromachine M.
Circuit theory shown in Figure 1 is described as follows: power circuit provide three groups of low-tension supply 0-3V, 0--V, 0-6V, 0-± two groups of positive-negative powers of 3V use for micromachine M, 0-6V power supply is used for controller, power supply is external additional supply, introduce by stereo socket 8, and connect controller 6,7 and micromachine 9 by lead 16.NE555 in the controller is a time-base integrated circuit, R
