Abstract

The utility model relates to a sitting posture corrector, which is used for studying desks of children. The utility model is composed of a base (1), a vertical rod (2), a middle rod (3), a transversal rod (4), a cushion ring (5) and a fixed pin (6). The vertical rod (2), the middle rod (3) and the transversal rod (4) are made of organic glass plate materials. Height adjustment holes (7) with equal distance are arranged on the vertical rod (2); a long bar-shaped hole (8) and a semicircular hole (10) are arranged on the middle rod (3), and the middle rod (3) can move up and down along the long bar-shaped hole (8) to adjust the height; the transversal rod (4) can rotate along a hinged center to be folded with the middle rod (3). The height is convenient to adjust by using the utility model; simultaneously, the utility model can be folded when not used, and the area of the whole corrector can be reduced to cause the utility model to be carried conveniently.

Description

Seating posture corrector for child when studying by desk

The utility model relates to the children that use on a kind of desk and learns the correcting sitting posture device.

At present, children generally do not make children keep the device of correct sitting posture on the desk that school study is used.Because, when children learn, be difficult for keeping correct sitting posture, if things go on like this, certainly will influence the normal development of children's vertebra and children's eyesight is descended.When being learnt, children keep good sitting posture; people have designed many protective devices; patent documentation CN 2054997U discloses the correcting posture device of using on a kind of desk; this device is made up of base, support and T font support bar; though structure is simpler, support bar is that sleeve pipe is connected with support, and the montant of T font support bar and cross bar are dead for weldering; this obviously makes the area of whole device bigger, so not portable.

The purpose of this utility model is a kind of can folding of design, can conveniently regulate height again; And it is little to account for area, learns the correcting sitting posture device with children on the portable again desk.

The utility model is achieved like this: it is made up of base, montant, intermediate bar, cross bar, steady pin and packing ring etc.Montant is vertical with base, the employing rivet is affixed, montant and intermediate bar are hinged by rivet, the two can move mutually, when making the two fixedly, can insert steady pin at its adjustment hole, cross bar, packing ring and intermediate bar are hinged by rivet, cross bar and intermediate bar in vertical state, whole correcting sitting posture device by base directly be fixed on desk the table along last.Cross bar, montant and intermediate bar are that methacrylate sheet is made, and base, packing ring and steady pin are carbon steel material.The adjustment hole that some equidistant equal apertures are arranged on the montant of this correcting sitting posture device, one strip hole is arranged on the intermediate bar, in order to regulate different height children's correct sitting posture height, have one and the semicircle hole of montant adjustment hole equal aperture in its bottom, to use steady pin, the fixing no longer relative operation of dead montant with intermediate bar.In time spent not, only need whole device is taken off from desk, pull out steady pin, intermediate bar is glided, and with the cross bar half-twist to overlap with montant, intermediate bar, can keep flat on the table, or put into school bag.

After using the utility model, can be according to children's height to adjust the height of correcting sitting posture device, avoided between children's study constantly one long, forward lean makes deformation of spinal column and eyesight variation, and simultaneously, this folding device is convenient, and institute takes up space little, easy to carry.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a front view of the present utility model.

Fig. 2 is a left view of the present utility model.

Fig. 3 is the front view of intermediate bar.

Fig. 4 is the front view of montant.

With reference to diagram, the utility model is made up of base (1), montant (2), intermediate bar (3), cross bar (4), packing ring (5) and steady pin (6).Montant (2), cross bar (4) and intermediate bar (3) are 5 * 30 millimeters methacrylate sheet.The adjustment hole (7) that some equidistant equal apertures are arranged on the montant (2), the end of intermediate bar (3) has the adjustment hole (7) of semicircle hole (10) and montant (2) isometrical, one strip hole (8) is arranged in the middle of it, cross bar (4) can around and the axle center of intermediate bar (3) hinge rotate to 90 ° to be superimposed with each other, take down steady pin (6), intermediate bar (3) moves down along strip hole (8) by rivet, to dwindle its whole spatial area.

Claims

1, the children that use on a kind of desk learn the correcting sitting posture device, form by base, montant, intermediate bar, cross bar, packing ring and steady pin, it is characterized in that: montant (2) and base (1) are affixed by rivet, montant (2) and intermediate bar (3) are hinged, one strip hole (8) is arranged on the intermediate bar, and intermediate bar (3) can move up and down along strip hole (8), intermediate bar (3) and cross bar (4) are hinged, and it is orthogonal, cross bar (4) can go to along hinged center and intermediate bar (3) overlaps, in steady pin (6) patchhole (7) and the semicircle hole (10).

2, correcting sitting posture device according to claim 1, the material of montant (2), intermediate bar (3) and cross bar (4) is a methacrylate sheet.
