Description

Sitting posture correcting unit for child studying

The utility model has related to a kind of child health care utensil, and a kind of specifically infantile study is commonly used the correcting sitting posture device, is specially adapted to children, and student study corrects faulty sitting posture and sighting distance when writing, and makes children's normal development and grows up healthy and sound to ensure to learn.

In order to prevent that children and juvenile student are crooked or to climb volt and on desk, learn to write, existing more existing children's study are write and are used health care device, as " using pupil's reading and writing sighting distance correcting posture device " more, " pupil's myopia prevention locating rack " etc., these health care devices are can both degree different plays correct that children learn sitting posture attached and helps effect, and still, these utensils mostly need to turn screw and regulate fixing, the structure more complicated, it is not quite convenient to use.

The purpose of this utility model be to release a kind of simple in structure, regulate children easy to use and learn the correcting sitting posture device, the incorrect sitting posture problem so that children are corrected in better solution ensures growing up healthy and sound of children.

Task of the present utility model is to be finished by the carriage of an adjustable-height position and the bearing that can be fixed on the desk.Hold-down support is made up of column and base plate, base plate is a square or rectangular flat plate, below base plate, be fixedly connected with a clip, in the base plate front, vertically central authorities are connected with a column, column becomes 70-80 ° of angle with base plate plane, column can be to be fixedly connected on the base plate, also can be by a torsion spring mechanism, be movably connected on the base plate when flexibly connecting column and can move folding on base plate, column is a middle square bar that has square hole, is fixed with the spring pin that a head becomes wedge-like on a side of column, and the head of pin is inserted in the square hole of column by the hole, a garden on the column side; Carriage be generally the Y type or

Type, the shank of carriage can be inserted in the square hole of bracket upright post, equipped portion also can slide up and down in square hole with square hole, carriage shank one side indentation, just be interlock by the pin of column side insertion with the sawtooth of carriage handle side and contact when the carriage handle inserts back in the square hole of column, stop the slip of carriage handle in the column square hole, defined the height and position of carriage.During use, on the bead of desk, rectifier is fixed on the desk clip on the seat board.Positioning pin column is extracted, slided up and down carriage handle bracket, positioning pin column is inserted in the hole of column again, carriage is located in itself and a certain sawtooth interlock to the height and position that needs.

The spring pin can also can be located with springs control with garden post spring control location.

That great advantage of the present utility model is is simple in structure, it is easy to use to regulate, and bigger practical value and promotional value are arranged.

Specific embodiment of the utility model is provided by following accompanying drawing.

Accompanying drawing is the structural representation of the correcting sitting posture device done according to the utility model.

Among the figure, (1) is for fixedly clip, (2) are that base plate, (3) are sawtooth carriage handle on for pin hole, (10) for spring pin, (11) for carriage, (9) for carriage handle, (8) for column, (7) for the square hole of column, (6) for torsion spring, (5) for spring(-supported) mount, (4).

Clip (1), base plate (2) and column (6) have been formed the bearing of rectifier.Carriage (8) is inserted in the square hole (5) of column (6) by its shank (7), make the carriage can only axially moving up and down along column square hole (5), because column (6) becomes 70～80 ° of angles of hypsokinesis with base plate (2), so carriage also becomes 70～80 ° hypsokinesis angle with base plate plane.During use, fixedly clip (1) is clipped on the bead of desk, extract spring pin (10), height and needs according to children move up and down bracket to suitable height and position, the spring pin is inserted in the pin hole (9), make sawtooth (11) interlock of its head and carriage handle, can with the carriage positioning instant.

Claims (2)

1, a kind of by carriage (8), geometrical clamp (1), base plate (2), the infantile study that column (6) and detent mechanism are formed is commonly used the correcting sitting posture device, the column (6) that it is characterized in that this rectifier and the plane of base plate (2) are at 70～80 ° of angles, a side indentation (11) of carriage (8) shank, detent mechanism is a spring pin (10), by the cooperate location of realizing carriage (8) of spring pin (10) with carriage handle serrated face (11), column (6) is to be movably connected by a torsion spring (4) with base plate (2).

2, rectifier as claimed in claim 1, the control retainer spring that it is characterized in that spring pin (10) can be garden post helical springs, also can be sheet springs.
