The purpose of this utility model provides a kind of stable drive, vision correction instrument easy to use.

Another purpose of the present utility model provides a kind of vision correction instrument that can massage the eye acupuncture point.

In order to realize above-mentioned the purpose of this utility model, a kind of vision correction instrument of the present utility model, it comprises that a casing, is arranged on the mechanical transmission mechanism of supply unit, an optical imaging system, a piece of scenery device and a transmission piece of scenery device in the described casing; Described casing is made up of a base, a cover plate, a light-passing board and a backboard; Described optical imaging system is installed in the low range convex lens that the eyepiece stalk and two on the described backboard is separately positioned in the described eyepiece stalk by two and forms; Described piece of scenery device is arranged on the three-dimensional piece of scenery that the slide-and-guide plate, on the described base places the piece of scenery frame and on the described slide-and-guide plate to be arranged on the described piece of scenery frame by one and forms; Described mechanical transmission mechanism comprises that one is fixed on drive motor, on the described base and is installed in worm screw, gear reduction parts, a fluted disc and its two ends on the output shaft of described motor and is hinged on connecting rod on described fluted disc edge and the described piece of scenery frame respectively, and described deceleration component is meshed with described worm screw and described fluted disc respectively.

Vision correction instrument of the present utility model, it also comprises a massage machine, and elastic massage piece, on the described backboard lateral surface, that match with the eye circular arc basically is arranged on the vibrating motor on the described backboard medial surface to described massage machine and the vibrating mass that is installed on the output shaft of described vibrating motor is formed by being arranged on.

The utility model has the advantages that owing to be used in electronic machine driving, therefore can guarantee effectively that a piece of scenery in the machine is slowly and reposefully parallel mobile in the speed with round about four times of per minute between distant view point 70mm and the close shot point 30mm, improve therapeutic effect thus; Owing to set up massage machine, myopia preventing and treating and eye health massage two big functions are organically combined, thereby improved the effect of myopia greatly, and enlarged the range of application of instrument.

Below in conjunction with accompanying drawing most preferred embodiment of the present utility model is described in detail, therefrom can see the more advantage of this utility model.

Fig. 1 is the front view of vision correction instrument of the present utility model;

Fig. 2 is the vertical view that has partial cutaway of Fig. 1;

Fig. 3 is along the cutaway view of " A-A " line among Fig. 2.

Now referring to Fig. 1,2 and 3, vision correction instrument of the present utility model comprises casing, is arranged on supply unit, optical imaging system, piece of scenery device, mechanical transmission mechanism and massage machine in the casing.Casing is made up of base 1, cover plate 2, light-passing board 3 and backboard 4; Optical imaging system is installed in the low range convex lens 6 that the eyepiece stalk 5 and two on the backboard 4 is separately positioned in the eyepiece stalk 5 by two and forms; Piece of scenery device is by being arranged on slide-and-guide plate 7 in the base 1, placing the piece of scenery frame 8 on the slide-and-guide plate 7 and the three-dimensional piece of scenery 9 that is arranged on the piece of scenery frame 8 is formed.Described casing, optical imaging system and piece of scenery device basically with commonly used vision correction instrument in identical, therefore just do not given unnecessary details at this.Different is mechanical transmission mechanism, and it comprises drive motor 10, worm screw 11, gear reduction parts, fluted disc 12 and connecting rod 13.Drive motor 10 is installed in the base 1 that adjoins backboard 4, and worm screw 11 is installed on the output shaft of motor 10.The gear reduction parts are made up of three pairs of gears 14,15 and 16, wherein the worm gear in the first pair of gear 14 is meshed with worm screw 11, second, third is meshed to the pinion in the gear 14,15 with first, second respectively to the gear wheel in the gear 15,16, and the pinion in the 3rd pair of gear 16 is meshed with fluted disc 12.Certainly, worm screw 11, the three pairs of gears 14,15 and 16 and fluted disc 12 also can replace with drive mechanisms commonly used such as belt pulleys.Two ends of connecting rod 13 are hinged with the middle part of the circumferential edges of fluted disc 12 and piece of scenery frame 8 respectively.

Massage machine is made up of vibrating motor 20 and two vibrating mass 21 that the

elastic massage piece

17,18 and 19, that is arranged on backboard 4 lateral surface is arranged on backboard 4 medial surface.Elastic massage piece 17 is along the top edge and the lateral edges setting of backboard 4, and elastic massage piece 18 is made up of two substantially parallel massage blocks and is arranged on the optical imaging system below, and elastic massage piece 17 and 18 matches with the eye circular arc basically like this.Elastic massage piece 19 is arranged between two eyepiece stalks 6 and in the middle of it and inwardly concaves, and can prop up bridge of the nose both sides.Motor respectively has an output shaft for 20 liang, and two vibrating mass 21 are installed on the output shaft respectively and make the both sides of the center of gravity of two vibrating mass 21 at output shaft.
