Abstract
The utility model discloses a distance adjustable three-dimensional vision care overlook frame, and relates to a three-dimensional vision care overlook frame. The distance adjustable three-dimensional vision care overlook frame solves the problems that an existing vision care overlook picture only displays three-dimensional pictures of three-dimensional space, and compared with a real three-dimensional picture of the three-dimensional space, the existing vision care overlook picture is poor in vision care effect. According to the distance adjustable three-dimensional vision care overlook frame, a motor is arranged on the side wall of a frame body, a cam shaft is connected with an output end of the motor, a groove is formed in the outer edge of a cam, the cam is installed on the cam shaft in a sleeved mode, a three-dimensional display panel is split along a rectangular gradually contracting line, the three-dimensional display panel is not cut off, the three-dimensional display panel is arranged at the front end of the frame body, a roll ball is fixedly installed at the rear end of the three-dimensional display panel, and the roll ball can be arranged in the groove of the cam in a sliding mode. The distance adjustable three-dimensional vision care overlook frame is applicable to vision care.
Description
Technical field
This utility model relates to a kind of vision care and lookes far into the distance frame, and frame is looked far into the distance in the binocular visual acuity health care that is specifically related to a kind of scalable distance.
Background technology
The human lives from the information of extraneous Organ procurement, has 90% to be completed by eyes by sensory organ in the world of light.Reported according to professor Zheng Yuanyuan of ophthalmology branch of Chinese Medical Association on April 6th, 2012: pupil's rate of myopia is: 16.65%; Junior school student's rate of myopia is: 42.05%; High school student's rate of myopia is: 61.59%; Undergraduate rate of myopia is: 70.00%, occupy the second in the world.The myopia situation is very serious, presents the trend that becomes younger with heighten degree.7-9 year, obvious ascendant trend appearred in child myopia.The student is the future of motherland and the hope of family.Therefore, be concerned about student's vision, guarantee that teenagers healthy growth is the responsibility of the whole society.About 70% myopia all appears at the Juvenile development stage.Cause the principal element of adolescent myopia to have three: the one, inherited genetic factors, the 2nd, environmental factors, the 3rd, trophic factor.Congenital myopia is relevant with heredity; Simple myopia often is accustomed to relevant with environmental factors, use eye.Investigate near-sighted pathogenic factors and have two: the one, " 2 one in length short ", namely learning time long, use is long at the moment, the length of one's sleep is short.The 2nd, " more than two one is few ", namely homework is many, and various examinations are many, and extracurricular activities are few.Modern life eyes burden in addition, the long-time operation computer; Teleview; Play Station games has more accelerated the sickness rate of adolescent myopia.And at present, the protection eyes measure that students in middle and primary schools commonly use only rests on the eye exercises stage, and other effective tool and method is not yet arranged.
Vision care is looked far into the distance figure and is utilized psychology spatial perception principle, makes on the two-dimensional space plane and strongly demonstrates tridimensional solid figure to extension far away.Eyes rooted is looked far into the distance figure a kind of sensation that looks over, thereby can alleviate to a certain extent the asthenopia that causes in long-time close eye situation.At present, all paste vision care in most middle and primary schools classroom and look far into the distance figure, but find in investigation, existing vision care is looked far into the distance figure and is just demonstrated tridimensional solid figure, be not real three dimensional diagram shape, compare the vision care weak effect with real three dimensional diagram shape.
Summary of the invention
The purpose of this utility model is to look far into the distance figure and just demonstrate tridimensional solid figure in order to solve existing vision care, compare the problem of vision care weak effect with real three dimensional diagram shape, and then provide a kind of binocular visual acuity health care of scalable distance to look far into the distance frame.
the technical solution of the utility model is: a kind of binocular visual acuity health care of scalable distance is looked far into the distance frame and is comprised support body, stereo display panel, motor, camshaft, cam and ball, motor is arranged on the sidewall of support body, camshaft is connected with the outfan of motor, the outer of cam is provided with groove, cam is sleeved on camshaft, cut open along rectangle convergent line on described stereo display panel, and stereo display panel does not cut off, stereo display panel is arranged on the front end of support body, the rear end of stereo display panel is fixed with ball, ball slidably is arranged in groove on cam.
Described binocular visual acuity health care is looked far into the distance frame and is also comprised by-pass cock, and by-pass cock is arranged on the lateral wall of support body, and controls the start and stop of motor.
Described binocular visual acuity health care is looked far into the distance frame and is also comprised a plurality of hooks, and a plurality of hooks are arranged on the upper end of support body.
Being pasted with one group of green vision care on described stereo display panel pastes.
This utility model compared with prior art has following effect:
1. this utility model rotates by the driven by motor cam, when ball slides in the groove of cam, ball drives stereo display panel and moves forward and backward, realized the distance adjusting of stereo display panel, and the stereo display panel of scalable distance cuts open along rectangle convergent line, be real three dimensional diagram shape, the vision care effect is looked far into the distance figure higher than two-dimentional vision care.
2. this utility model is simple in structure, is easy to realize, and is with low cost, is convenient to promote the use of in each middle and primary schools.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present utility model; Fig. 2 is the side view of Fig. 1.
The specific embodiment
the specific embodiment one: present embodiment is described in conjunction with Fig. 1 and Fig. 2, present embodiment comprises support body 1, stereo display panel 2, motor 3, camshaft 4, cam 5 and ball 6, motor 3 is arranged on the sidewall of support body 1, camshaft 4 is connected with the outfan of motor 3, the outer of cam 5 is provided with groove 7, cam 5 is sleeved on camshaft 4, cut open along rectangle convergent line on described stereo display panel 2, and stereo display panel 2 does not cut off, stereo display panel 2 is arranged on the front end of support body 1, the rear end of stereo display panel 2 is fixed with ball 6, ball 6 slidably is arranged in groove 7 on cam 5.
