Abstract

The utility model relates to a prevention device to myopia and vertebration deformation for students. One of the main components is an arc spacing stop lever and a spacing frame matching with the stop lever, both ends at the bottom of a furcation part of the spacing frame are transversely and correspondingly provided with a pair of ratchet end faces, the centre is provided with a bolt hole, and the other of the main components is a clamping device which clamps the spacing frame on a desk and is integrally formed, and the clamping device is composed of a clamping plate, a clamping arm, and a bolt sleeve tube. Two end faces of the bolt sleeve tube are also provided with ratchet end faces matching with the ratchet end faces on the spacing frame, a bolt penetrates through the ratchet end faces and the bolt sleeve tube and is firmly screwed by a nut, and the spacing stop lever can be inserted and pulled up and down in the spacing frame and is fixed at any position. The utility model has the advantages that the angle, the height, and the distance to a desk face of the spacing stop lever can be adjusted.

Description

Myopia of student deformity of spinal column prevention device

A kind of myopia of student deformity of spinal column prevention of the utility model device belongs to health treatment or school supply and stationery technical field.

Current primary and secondary students read a book, write all is to lie prone on desk, or cushion chin with head arm against with hand, can cause spinal curvature like this, form the deformity of spinal column, what have also can cause inclined to one side shoulder, bend neck, thereby influence the healthy development of health and the formation of vigorous and graceful figure, and can cause hypometropia, and the true and false rate of myopia of pupil reaches 21% at present, and the junior middle school reaches 63%, senior middle school reaches more than 88%, this all because incorrect reading, write, sitting posture causes.

The purpose of this utility model is to take good care of children and the teenager is healthy and the angle of social responsibility considered from care, a kind of myopia of student deformity of spinal column prevention device is provided, it can not only make the student form good body gesture, the prevention deformity of spinal column, the more important thing is myopia prevention in advance, to reach " 31 theory " requirement that State Education Commission proposes, i.e. " chest is from about desk one fist; eyes are from about books one chi, and finger holds a pen from about the books one-inch "

For achieving the above object, the utility model takes following technical proposals to realize, referring to Fig. 1-2.

One of important component of the present utility model is the spacing pin of arc (1) and the position-limited rack (2) that can cooperate with it, and there is horizontal relative ratchet end face (2c) at the two ends of fork portion (2b) bottom of position-limited rack (2), and there is bolt (6) hole in end face central authorities; Another important component is the clamping device of clamping position-limited rack (2) on desk, constitute by integrated clamping plate (3), jig arm (5), bolt sleeve (3a), respectively there is ratchet end face (3b) at bolt sleeve (3a) two ends, there is tightening screw rod (4) on jig arm (5) top, bolt (6) passes two ratchet end faces (2c) and bolt sleeve (3a), and by nut (6a) tightening, two bars of spacing pin inject downwards in two pipes of limiting frame (2), can upper and lowerly plug, fixing with lock-screw (2a).To regulate the height of spacing pin, regulate the angle of spacing pin (1), also can come adjustable clamp to be held in position on the desk by tightening screw rod (4).

Advantage of the present utility model is can be according to student's height, table stool size free adjustment to reach the degree of the most comfortable, realizes what State Education Commission proposed, chest from about desk one fist, eyes from about books one chi, finger hold a pen " 31 theoretical require " from about the books one-inch.The student is picked up good habits of study, with the pre-myopia prevention and the deformity of spinal column.

Description of drawings:

Fig. 1 is the schematic perspective view of myopia of student deformity of spinal column prevention device;

Fig. 2 is the side view of myopia of student deformity of spinal column prevention device.

Embodiment:

Fig. 1-2 is embodiment figure of the present utility model, and spacing pin (1) available metal is made position-limited rack (2), clamping plate (3), jig arm (5), bolt sleeve (3a), available metal or engineering plastics moulding.The spacing pin of arc (1) has Hose Jacket (1a), and nut (6a) is wing nut, is lined with elastic washer (6a).
