Abstract
The utility model discloses a myopia treatment instrument which comprises two convex lens and a therapeutic instrument shell; wherein, the therapeutic instrument shell is symmetrically provided with a plurality of light emitting diodes in even rows which are arranged in a way of wide in front and narrow in back and are controlled by a controlling device which controls one pair of symmetric light emitting diodes to give off light according to sight distance successively; a baffle plate is arranged between two groups of symmetric light emitting diodes, by which the light emitting diodes give off light successively instead of a longitudinal slide rail of liquid crystal screen to realize the far and close regulation of visual line of the short-sighted. Beside, the utility model has the advantages of greatly simplifying the mechanical structure, being light in weight, low in cost, being beneficial to popularize the product, and greatly raising the working life simultaneously.
Description
Technical field
This utility model relates to a kind of visual rehabilitation equipment, relates to a kind of therapeutic instrument for shortsightedness particularly.
Background technology
Existing therapeutic instrument for shortsightedness, comprise two lens, two liquid crystal display screens and beloid fixed rack, move two liquid crystal display screens front and back on fixed rack, the ultimate range of two liquid crystal display screens and minimum range all are fixed, and the sight line of each user distance is different, in use sight line distance and sighting target be not apart from being inconsistent, and asthenopia and discomfort can appear in life-time service.
And in inventor's a utility model patent, except beloid vertical slide rail is set, also be provided with the horizontal slide rail that vertically moves with sighting target, laterally slide rail can be regulated the sighting target distance, two liquid crystal display screens vertical slide rail and laterally the compound motion track on the slide rail better adapted to the people and see far, see near physiological process, solved life-time service and can produce visual fatigue and problem discomfort.
But above-mentioned therapeutic instrument for shortsightedness all needs to be provided with vertical slide rail and corresponding driving device, complicated in mechanical structure, and production cost is higher, gives to popularize to use and has brought adverse effect.
The utility model content
The purpose of this utility model is at the problems referred to above, provides a kind of frame for movement simple, low, the lightweight therapeutic instrument for shortsightedness of cost.
For achieving the above object, this utility model adopts following technical scheme: a kind of therapeutic instrument for shortsightedness, comprise two lens and therapeutic instrument housing, in described therapeutic instrument housing, be symmetrical arranged the even column light emitting diode, the light emitting diode of each symmetric arrays is front wide and rear narrow layout and luminous by control device control, this control device is luminous successively apart from the wherein a pair of symmetric light emitting diode of control according to sight line, and a dividing plate is set in the middle of the light emitting diode of two groups of symmetric arrays.
Because this utility model has adopted symmetrically arranged light emitting diode, realize the distance adjusting of patient's sight line by vertical slide rail of the luminous successively replacement liquid crystal display screen of light emitting diode, its frame for movement is simplified greatly, in light weight and cost is low, help popularizing of product, also improve greatly its service life simultaneously, it is opposed solely that the dividing plate that is provided with in the middle of light emitting diode can make two branch look visual space, avoids the both sides light emitting diode simultaneously binocular to be produced and interfere.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please read Fig. 1, therapeutic instrument for shortsightedness of the present utility model, comprise two lens 1 and therapeutic instrument housing 2, in described therapeutic instrument housing 2, be symmetrical arranged even column light emitting diode 3, the light emitting diode 3 of each symmetric arrays is front wide and rear narrow layout and luminous by control device control, this control device is luminous successively apart from the wherein a pair of symmetric light emitting diode of control according to sight line, in the middle of the light emitting diode 3 of two groups of symmetric arrays a dividing plate 8 is set.Described control device can be a control circuit.Be provided with two liquid crystal display screens 4 in described light emitting diode 3 fronts, between two liquid crystal display screens 4, be provided with lateral adjustment, this lateral adjustment is by being installed in the opposite screw 5 of each liquid crystal display screen 4 times and rotation direction, constituting with the screw mandrel 6 of screw 5 engagement and the motor 7 that drives screw mandrel 6, and described control circuit is luminous according to the symmetrically arranged light emitting diode of corresponding two row of described motor 7 Stroke Control 3.In described two liquid crystal display screens 4, can import synchronous video signal, produce the plane visual effect; Also can import and show and have the video signal that necessarily differs, thereby realize three-dimensional stereoscopic visual.Described light emitting diode 3 is arranged on described housing 2 bottoms, and it installs simple.
Consult Fig. 2, described control circuit is according to the pulse signal of the drive stepping motor 7 that detects, and can calculate the spacing between liquid crystal display screen 4 strokes and two liquid crystal display screens, thereby control is luminous successively with the symmetrically arranged light emitting diode 3 of corresponding two row of this spacing.Therefore the patient can by regulate two spacings between the liquid crystal display screen make it with sight line apart from adapting, control corresponding lumination of light emitting diode, the led lighting order can be from as far as closely, promptly from the liquid crystal display screen to lens, otherwise also can.
With way of example this utility model is illustrated above, but this utility model is not limited to above-mentioned specific embodiment the protection domain that all any improvement done based on this utility model or modification all belong to this utility model claim.
Claims (5)
