Description
Technical field
The utility model relates to chair and desk for pupils field, specifically belongs to tilting-type myopia prevention active desktop.
Background technology
Myopia and hunchback are the ubiquitous problems of students in middle and primary schools, and body development and the health of youngsters and children in serious harm.Scientific research result shows recently: causing myopia and bow-backed main cause is owing to having adopted bad sitting posture to cause.Sitting correction set is pre-myopia prevention and bow-backed key point.But how allowing children in long learning process, consciously keep consistently good sitting position, is but a global problem, does not still find so far really effectively solution.
The defect of conventional chair is: a lot of father and mother think that children's incorrect sitting-pose is because tired institute causes, but it is because the unreasonable structure of chair causes in fact that few people know bad sitting posture, the structure of conventional chair is " h " type (facing perpendicular type directly) substantially, while taking a seat, the weight of human body mainly contains buttocks and thigh root bears, in the time of study, work, angle between upper body and thigh is generally less than 90 degree, upper body becomes " c " type, this sitting posture can make people's spinal curvature naturally, shank, waist, hall portion burden, sitting is had a pain in the back.For the children of long-time seat study every day, be to can't bear to stand really, unconsciously just bend over to have lain prone on desktop, if things go on like this, child's back just easily forms " c " type.Can say, this structural critical defect of conventional chair is to cause child myopia and bow-backed real arch-criminal.
Utility model content
The purpose of this utility model is to provide a kind of tilting-type myopia prevention active desktop, dismounting is easy to carry flexibly, can be installed on arbitrarily above the desk in classroom, in the study table of family, the angle of inclination of drop table panel is adjustable arbitrarily, has ensured reading and the sight angle that writes, health need not lean forward, need not bow, thereby prevent myopia and bow-backed, improve the comfort level of study.
The technical solution of the utility model is as follows:
Tilting-type myopia prevention active desktop, include drop table panel, left chute, right rail, left chute is fixedly connected with integral with right rail by connecting rod, left chute, right rail front end is with fixing buckle, rear end is slidably fitted with adjustable plate, the rear end of adjustable plate is fixed with movable buckle, fixing buckle and movable buckle be engaged with desktop before, rear end, the front end of drop table panel is articulated with left chute, on right rail, left chute, the groove bottom at right rail rear portion is provided with jagged draw-in groove, drop table panel is hinged with support bar on bottom surface, support bar end has the convex tendon matching with draw-in groove, on the cell wall of jagged draw-in groove side top, have gathering sill, support bar end is provided with the guide finger matching with gathering sill, there is arc-shaped transition groove below, gathering sill rear end, there is square groove gathering sill front end below.
Described gathering sill below cell wall is provided with baffle plate, and baffle plate can keep off and be placed in described guide finger.
On drop table panel of the present utility model, be hinged with support bar, the convex tendon of support bar lower end matches with left chute and the jagged draw-in groove of right rail, realize the location, angle of inclination of drop table panel, in the time that the guide finger of support bar lower end enters gathering sill through arc-shaped transition groove, drop table panel is set level gradually, final guide finger enters square groove, and drop table panel is the level of state.
The utility model can be installed on arbitrarily in classroom desktop, and the angle of inclination of drop table panel is adjustable arbitrarily, has ensured reading and the sight angle that writes, and health need not lean forward, and need not bow, thereby prevent myopia and bow-backed, has improved the comfort level of study.
