Description

Eyesight recovery training instrument for multiple people

Technical Field

The utility model relates to a vision recovery training instrument, in particular to a vision recovery training instrument for a plurality of people.

Background

At present, have multiple vision to amblyopia treatment and postoperative vision recovery training appearance on the market, but the lens cone of these training appearance often can't be adjusted, can't finely tune to different interpupillary distances, and training appearance on the market simultaneously divide into monocular and binocular formula, if there is vision change in the user later stage (if certain eye recovers in advance behind the binocular amblyopia), then need purchase again, makes use cost greatly increased.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

An object of the utility model is to provide a vision recovery training appearance that many people crowd used, applicable in the crowd of different interpupillary distances to do not confine to monocular or both eyes. In order to achieve the above purpose, the utility model adopts the following technical scheme:

(II) technical scheme

The utility model provides a many people crowd's eyesight resumes training appearance, includes base, body, two lens tubes, pivot and optical brush, the body is fixed on the base, the optical brush is inserted by the side in the body, the pivot is fixed in the body, two lens tubes all with pivot rotatable formula is connected, the lens tube is extending structure.

Further, the lens cone comprises an extension tube and a window sleeve, and the window sleeve is connected with the extension tube through threads.

Further, the lens cone is of an elastic telescopic structure.

Further, the lens barrel is of a telescopic multi-layer sleeve structure.

Further, the two lens barrels rotate around the rotating shaft in a synchronous and reverse direction.

Preferably, the rotating shafts are two parallel shafts, the two lens barrels are respectively connected with the rotating shaft on the same side through a connecting piece, and the two connecting pieces are meshed through a gear.

(III) advantageous effects

Compared with the prior art, the utility model has obvious advantages and beneficial effects, particularly, the lens cone is arranged to be adjustable in distance, and is suitable for people with different interpupillary distances; and the telescopic lens cone design can be used no matter whether single-eye or double-eye needs to be used for vision recovery training, so that the purchase cost of a user is reduced.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The present invention will be further described with reference to the accompanying drawings and the detailed description.

Referring to fig. 1 and 2, an eyesight recovery training instrument for multiple people comprises a base 1, a body 2, two lens barrels 3, a rotating shaft 4 and an optical brush 5, wherein:

the body 2 is fixed on the base 1, the optical brush 5 is inserted into the body 2 from the side, and the rotating shaft 4 is fixed in the body 2; in view of the fact that the interpupillary distance of each person is different, especially the interpupillary distance of adults and children, and people who need to perform vision recovery training are not limited by age, in order to adapt to different people, the two lens barrels 3 are rotatably connected with the rotating shaft 4, and a user can adjust the distance between the two lens barrels 3 according to the interpupillary distance of the user; furthermore, the person needing to do the vision training is not limited to a single eye or two eyes, so the lens barrel 3 is of a telescopic structure, and the lens barrel can be folded up during the single-eye training without closing the eyes by self so that the lens barrel 3 can press the eyes.

The top of the lens barrel 3 is often contacted with eyes, and cleaning and disinfection are often needed, so that the lens barrel 3 consists of an extension tube 31 and a window sleeve 32, the window sleeve 32 is connected with the extension tube 31 through threads, and the window sleeve 32 is directly screwed down when cleaning is needed.

In order to facilitate the extension and retraction of the lens barrel 3, the lens barrel 3 is of an elastic telescopic structure or a telescopic multi-layer sleeve structure.

Because the human eyes are symmetrically distributed, the two lens cones 3 are required to be synchronously adjusted when the distance between the lens cones 3 is adjusted, and specifically, the two lens cones 3 rotate around the rotating shaft 4 in a synchronous reverse rotation manner; more specifically, as a preferred embodiment, the rotating shafts 4 are two parallel shafts, the two lens barrels 3 are respectively connected with the rotating shaft 4 on the same side through a connecting piece 6, the two connecting pieces 6 are engaged through a gear 61, when one of the lens barrels rotates, the other lens barrel can be synchronously adjusted along with the rotation of the other lens barrel, and the two lens barrels 3 are symmetrically distributed.

The utility model discloses a design point lies in setting the lens cone to the crowd that is applicable to different interpupillary distances of distance adjustable and retractable to no matter monocular or eyes need carry out the vision recovery training, all can use, reduce user's purchase cost.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
