Abstract

The utility model relates to a health care and studying frame for preventing myopia which belongs to the technical field of reading and learning. The learning frame is composed of a splint, a torsion spring, a blocking plate, and a supporting plate. The supporting plate and the splint are connected with a pin shaft through a pin shaft frame on the supporting plate. The torsion spring is wrapped round the pin shaft, and one end is pressed on the supporting plate and the other end is pressed on the splint to form a spring splint. Either the jointed place of the supporting plate or the jointed place of the blocking plate is provided with a pin shaft sleeve. The pins pass through the pin shaft sleeves to form a hinged plate structure. The utility model has the advantages of simple structure, convenient portability and good structure strength. When the utility model is used, the spinal curvature caused by the improper poses of students can be prevented to make the students fall into the habit of good writing and reading poses.

Description

Health studying folder for preventing myopia

The utility model belongs to look at reads study frame technical field, is that a kind of pre-myopia prevention health science is practised frame.

Common many pupils do not note the posture of reading and writing for a long time, the long eyes amblyopia myopia that just causes easily of time.In order to make children keep correct read-write posture, about stipulating student's writing posture, education department to adhere to by " books from eye distance from be that distance is a fist between one chi, chest and table ".Yet occur some pupil reading and writing posture corrector at present on the market and all be difficult to satisfy simultaneously these requirements.

The purpose of this utility model be to provide a kind of can control chest and desktop distance and eyes and books distance, easy to use, be easy to install and remove the pre-myopia prevention health science that carries and practise frame.

The purpose of this utility model realizes with the following methods.This pre-myopia prevention health science is practised frame, comprise clamping plate, torsion spring, baffle plate, support plate, support plate is connected with bearing pin by the bearing pin frame on the support plate with clamping plate, torsion spring is on bearing pin and an end is pressed on the support plate, the other end is pressed in and forms spring clip plate on the clamping plate, all there is pin sleeve support plate and baffle plate joint, and pin passes pin sleeve and forms the hinge plate structure.The utility model will be further described below in conjunction with the embodiment accompanying drawing.

Fig. 1 the utility model front view;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the left side view of Fig. 1;

Fig. 4 is the cutaway view after the utility model folding.

Among the figure: 1-baffle plate, 2-support plate, 3-pin, 4-clamping plate, 5-torsion spring, 6-bearing pin, 7-desk, 8-window, 9-pin sleeve, 10-bearing pin frame.

It is that a fist is wide from spring clip plate upper pin frame (10) apart from S that baffle plate (1) and support plate (2) all can adopt sheet metal such as iron plate or plastic plate, pin (3), for ease of folding, the window (8) greater than clamping plate (4) is arranged on baffle plate (1).Bearing pin frame (10) is that also bending and rectangular two platelets of support plate face on one side under the poison ivy severed at last two places of support plate (2), boring a hole on each platelet for bearing pin (6), torsion spring (5) being installed on bearing pin (6), clamping plate (4) also are hinged on bearing pin (6) and upward form the spring clip plate structure.

During use, spring clip plate is clipped on the desk (7), baffle plate (1) is vertical, because hinge plate structure in baffle plate (1) and support plate (2) upper pin cover (9) and pin (3) formation, make baffle plate (1) be in the position of vertical support panel (2), the user is against on the baffle plate (1) with chest, and like this, chest and desk edge keep the distance of a fist.And the chair height that can tell and to sit, keep books from eye distance from be one chi, when not using, spring clip plate can be broken away from desk (7), and baffle plate (1) is rotated counterclockwise 270 °, like this, just become folding state shown in Figure 4, be convenient to put into school bag and carry or be concealed in the desk.

The utility model is simple in structure, and structural strength is good, and is durable in use, easy to carry, can prevent the spinal curvature that the student causes because of posture is improper, makes the student from forming good writing and reading the posture custom for a short time, for later healthy growth is laid a good foundation.
