Description

The anti-myopia gesture-correction seat

Technical field

The utility model belongs to a kind of seat, specifically, is a kind of myopia prevention seat that is used to correct faulty sitting posture.

Background technology

According to up-to-date science statistics, China myopia children have been the development that becomes younger, just account for 30% among 10000 children of preliminary understanding visual problems is arranged, the investigation show except that minority partly be the genetic cause, mostly be because from the little better learning sitting posture of not forming, child is sitting in seat and sees written word, unconsciously will croucs, eyes have only the head of a family by the next door to remind on the side near books always, just raise one's head again, the head of a family is aside the time, and child will be for a long time always near books, the in-plant like this written word of seeing of eyes, eyes to child have very big injury, long-term so artificial hypometropia that causes of understanding.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of myopia prevention seat that corrects faulty sitting posture.

The technical solution of the utility model is as follows: a kind of anti-myopia gesture-correction seat, comprise seat, backrest, chair leg, its key is: both sides, described backrest upper end are equipped with the belt perforation, there are two straps to pass this belt perforation respectively, described belt one end is fixed on described backrest lower side, the other end is fixed on described seat rear end face, and the pin and the described back post of described backrest lower end are hinged, and this backrest can overturn 1～30 ° forward around this hinge.Above child is sitting in, two hands pass belt, this belt entangles two shoulders, when child turned forward unconsciously, backrest can be along with upset forward, and backrest is become angled two straight lines that connect together by straight line, need longer belt to stretch tight behind backrest, belt before the backrest shortens, and makes the belt that is enclosed within on the child be stretched tight very tightly, and the whole backrest of chair firmly touch child's the back of the body, make the people be difficult to be subjected to, remind child just will sit constantly, keep good posture, after child just sits, backrest is upset forward not, belt also fluffs thereupon, even fully imperceptiblely has belt to entangle oneself, and oneself reading and writing is had not a particle of influence.

Described back leg has extended upward contiguous block, this contiguous block upper end recessing, one of an iron block inserts in this groove also hinged with it, this iron bar other end is inserted in the described lazyback foot fixing, described backrest bipod is extended with limited block downwards and fit in the back post upper surface, leave the gap between described limited block and the contiguous block, and limited block is longer than contiguous block.When backrest does not overturn forward do not fit in limited block and described backrest bipod lower surface, do not turn over to backrest is spacing, the limited block side props up the contiguous block head when overturning forward, no longer forward upset, the limited block afterbody props up belt, the Len req of behind the backrest belt of stretching tight when increasing the backrest upset.

Described limited block upper surface is provided with the flexible glue convex closure, and limited block plays certain cushioning effect when spacing to backrest.

Described every strap is linked to each other by the snap lock that is positioned at backrest the place ahead by two parts, and described every strap (4) is provided with the strainer of regulating degree of tightness, makes things convenient for belt to be enclosed within young child and adjusting belt degree of tightness.

Beneficial effect: the utlity model has be skillfully constructed, simple in structure, implement easy, with low cost, etc. characteristics, can remind child to keep sitting posture to rectify constantly, effectively prevent the myopia that the too close books of eyes cause, the while does not have any impact to child's reading and writing again.
