Utility model content
the technical problems to be solved in the utility model is to provide a kind of sighting target apart from adjustable sight training instrument, regulate sighting target apart from (distances between display screen and rib lens) by gear drive, actuating device takes up room little, synchronicity is good, noise is low, can build better visual training environment for user.
To achieve these goals, technical solution adopted in the utility model is: a kind of sighting target is apart from adjustable sight training instrument, comprise that housing, symmetry are arranged on two groups of vision training apparatus and the actuating device on housing, described vision training apparatus comprises the rib lens that are embedded on described housing antetheca and is arranged on the display screen in housing; Described actuating device comprises two chutes being symmetricly set in described housing, be arranged on slide rail in chute, be arranged on the display screen supporting plate on slide rail, the teeth that are arranged on the bar shaped of display screen supporting plate inner side, the follower gear engaging with teeth, driving gear and for driving the clockwise and anticlockwise motor of driving gear, two follower gears are meshed, driving gear is meshed with arbitrary follower gear, is provided with control button on described housing.
As a kind of optimal technical scheme of the present utility model, described slide rail is two bar slide rails, and the angle of two slide rails is 0 ° ~ 45 °, and the upper end distance of two slide rails is less than or equal to lower end distance.
As a kind of optimal technical scheme of the present utility model, described clockwise and anticlockwise motor is coupling with driving gear or is connected by worm screw.
As a kind of optimal technical scheme of the present utility model, in its structure, also comprise and be vertically arranged on the middle dividing plate of enclosure interior.
As a kind of optimal technical scheme of the present utility model, described rib lens tip is provided with rubber ring.
As a kind of optimal technical scheme of the present utility model, in its structure, also comprise speaker.
As a kind of optimal technical scheme of the present utility model, described clockwise and anticlockwise motor is by numerical control device control, and the driving device of described two display screens is connected in parallel to the same video circuit.
The beneficial effect that adopts technique scheme to produce is: this utility model regulates sighting target apart from (distances between display screen and rib lens) by gear drive, actuating device takes up room little, synchronicity is good, and noise is low, can build better visual training environment for user.
brief description of the drawings
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1, housing 2, chute 3, slide rail 4, display screen supporting plate 5, display screen 6, driving device 7, rib lens 8, rubber ring 9, clockwise and anticlockwise motor 10, driving gear 11, follower gear 12, numerical control device 13, dividing plate 14, teeth.
Detailed description of the invention
Referring to accompanying drawing 1, the structure of a detailed description of the invention of this utility model comprises that housing 1, symmetry are arranged on two groups of vision training apparatus and the actuating device on housing 1, and described vision training apparatus comprises the rib lens 7 that are embedded on described housing 1 antetheca and is arranged on the display screen 5 in housing 1; Follower gear 11 that described actuating device comprises two chutes 2 being symmetricly set in described housing 1, be arranged on slide rail 3 in chute 2, be arranged on display screen supporting plate 4 on slide rail 3, be arranged on the teeth 14 of the bar shaped of display screen supporting plate 4 inner sides, engage with teeth 14, driving gear 10 and for driving the clockwise and anticlockwise motor 9 of driving gear 10, two follower gears 11 are meshed, driving gear 10 is meshed with arbitrary follower gear 11, on described housing 1, is provided with control button.
Described slide rail 3 is two bar slide rails, and the angle of two slide rails 3 is 30 °, and the upper end distance of two slide rails 3 is less than lower end distance.In the time that display screen 5 moves up, the distance synchronous between two display screen 5 spacing, display screen 5 and eyes dwindles, otherwise synchronously increases, and meets the physiologic habit of human eye, object from eyes more close to, its sight line angle of radiation is less, otherwise larger.
