Abstract

The utility model relates to a foldable sitting posture corrector for reading and writing, which is composed of a fixed clamping seat, a telescopic bracket and a limiting device. The limiting device is formed by connecting a left limiting transversal rod, a right limiting transversal rod and horizontal grooves on the upper parts of the support seats of the transversal rods in an inserting sheath mode or a shaft sleeve mode. The support seats of the transversal rods are movably connected with the top end of the telescopic bracket, and the telescopic bracket is composed of a hollow inner framework and a hollow outer framework; the two limiting transversal rods can be inserted into the inner cavity of the inner frame of the telescopic bracket after the two limiting transversal rods are vertically folded. The utility model has the advantages of simple structure, easy manufacture, small volume, etc.; the sitting posture of students can be effectively controlled, the utility model can be folded, and the utility model is convenient to carry by the students in clothes bags and schoolbags.

Description

But folding read-write sitting posture rectifier

The utility model relates to a kind of attached frame device of learning with desk, especially relates to the correcting sitting posture device that a kind of student of making keeps correct read-write posture.

Now the desk that uses of student does not generally have to make the student to keep the attachment device of correct body position, and the student be in reading, often can not keep correct body position when writing, and easily suffers from disease such as myopia, hunchback in the course of time and influences the health normal development.People have studied multiple correcting sitting posture device for this reason, but have complex structure, and volume is big, can not folding, and inconvenience such as carries at shortcoming.

The purpose of this utility model provides a kind of simple in structure, and volume is little, but the gesture rectifier is sat in folding easy to carry read-write.

The purpose of this utility model is achieved in that by Fixing clamp-seat, jack column, but in the folding read-write sitting posture rectifier that stopping means is formed, stopping means by about two spacing cross bars, cross bar bearings constitute, cross bar bearing top is provided with the groove of a level, one end of spacing cross bar is connected in the groove on the cross bar bearing with hosel or axle sleeve mode, the top of cross bar bearing bottom and jack column flexibly connects, jack column is configured to by the inside and outside of hollow, and two spacing cross bars can be inserted in the internal frame inner chamber of jack column after vertically drawing in.

Stopping means of the present utility model and jack column are dismountable flexible connection, after pulling down two spacing cross bars are vertically closed up the internal frame inner chamber that inserts jack column, and internal frame can shrink in the outrigger cavity, and overall volume is little after the folding, is portable " one " font.So compared with prior art, the utlity model has following advantage:

1, simple in structure, be easy to make, easy to use, can effectively control the pupil reading and writing sitting posture, keep eyes and book, this correct distance.

But 2 foldings, volume is little, is convenient to the student and is put in clothes bag, the school bag and carries.

3, jack column adjustable height, the student of can suit all ages and classes, different heights uses.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model one embodiment.

Fig. 2 is the cutaway view after the utility model one embodiment folding.

---Fixing clamp-seat, 2---jack column, 3---spacing cross bar, 4---cross bar bearing, 5---groove in Fig. 1, Fig. 2: 1.

Fig. 1, Fig. 2 can find out: a specific embodiment of the present utility model is: but in the folding read-write sitting posture rectifier of forming by Fixing clamp-seat 1, jack column 2, stopping means, stopping means by about two spacing cross bars 3, cross bar bearing 4 constitutes, cross bar bearing 4 tops are provided with the groove 5 of a level, one end of two spacing cross bars 3 and the groove 5 corresponding sheath holes that are provided with, insert the sheath hole with latch and realize that spacing cross bar 3 is connected with the bolt-type of cross bar bearing 4, when two cross bars 3 get out, be symmetrical horizontal, then be vertically shape side by side after the gathering.Also can adopt the axle of establishing a projection in the end of cross bar 3, in groove 5 correspondences a pivot (hole) is set, realize that cross bar 3 is connected with the axle sleeve mode of bearing 4.Jack column 2 is lumped together by inside and outside slip cap of hollow to be formed, and its position adjustments, fixing tapered thread, nut or the laterally pushed type screw rod of adopting are finished.The bottom of cross bar bearing 4 is a column, can tightly be inserted in the socket type of realizing the two in the inner chamber of jack column 2 and connect, and also can screw thread be set at the two correspondence position and be threaded.Certainly also can adopt other usual manner to flexibly connect, can insert in the internal frame inner chamber of jack column 2 after two spacing cross bars 3 vertically close up.The bottom of jack column 2 is provided with retaining thread, and the last clamp of Fixing clamp-seat (1) is provided with fixing threaded hole, and this fixing threaded hole penetrates clamp on this; Fixing clamp-seat 1 is connected with support 2 with fixing threaded hole by this retaining thread, and support 2 is screwed in Fixing clamp-seat, and (the inside groove appropriate depth tightens Fixing clamp-seat 1 and is fixed on table along last, can not establish fixture in addition and be used for fixing the fixing of deck and table edge.

During use, the utility model installed be fixed on the table, regulate the height of jack column, sitting posture in the time of then can controlling student (especially primary and secondary students) reading effectively, guarantee that eyes and book, this distance are correct, prevent that diseases such as myopia and hunchback from taking place, and ensures the normal development of student's health.Not the time spent, draw jack column in, take off stopping means, vertically close up two spacing cross bars, insert the internal frame inner chamber of jack column, then volume is small and exquisite, is " one " font, can be placed in student's school bag, the clothes bag, is convenient for carrying.

Claims
