Abstract

Multifunction health desks and chairs for middle and primary school pupils are all provided with a lifting mechanism which can adjust the height of the desks and chairs to meet the needs of pupils of different heights. The adjustment is achieved through the upward and downward movements of a U-shaped frame arranged on a bracket or a chair frame. The plates of a tabletop and a chair seat are fixed on the U-shaped frame. The front of the plate of the tabletop is provided with a stadia distance governor mechanism consisting of a limit frame and a limit bar to correct sitting position and keep stadia distance; therefore, the spinal columns of the pupils are in a natural bending state to prevent humpback. The rear of the plate of the tabletop is provided with a bookshelf; therefore, when reading, pupils can keep a consistent visual angle to prevent myopia. The utility model has a plurality of functions and adopts a square tube steel structure and bolt connection; therefore, the utility model is stable and reliable, and has a wide application range and is convenient to manufacture, assemble and transport.

Description

Primary and secondary students use the multi-function health-care desk and chair

Technical field:

The utility model relates to a kind of teaching equipment, exactly is that a kind of primary and secondary students use the multi-function health-care desk and chair.

Background technology:

The desk and chair that China primary and secondary students use for a long time, remains in the traditional habit always.As: the tables and chairs height can not be adjusted, and student's sighting distance is under no restraint and limits, and sitting posture is improper etc.Go down like this in addition child from the kindergarten to the primary school, or grow in the golden period to the growth in junior middle school by primary school, do not obtain any correction.In the course of time, bad physiological phenomenons such as myopia, hunchback happen occasionally.Show according to interrelated data: phenomenons such as present China primary and secondary students myopia, hunchback are ascendant trend year by year.Therefore, designing a kind of adaptation primary and secondary students and use " multi-function health-care lifting desk chair " product as an alternative, is very urgent.

Chinese patent CN2346293Y discloses a kind of " the supporting tables and chairs of single-leg type myopia-preventing ".Its architectural feature is: its desk is to add the location latch by the lifting of single leg fit to be connected with the underframe of supporting seat.Though this structure is simple, can play lift action.But, can't eliminate because fit and bolt mechanism exist certain interval.And single leg supports less stable.It is to rising highly more, and tables and chairs rock just big more.Single leg fit lifting desk chair is not suitable for minority student and uses, and grows golden period because they are in to grow up.Myopia-preventing frame in " the supporting tables and chairs of single-leg type myopia-preventing " in addition, its limiting plate is microscler flat-square shaped, corner angle are more, cause injury accident such as collide with easily.

Summary of the invention:

Desk and chair provided by the utility model is intended to primary and secondary students are played many-sided health-care effect, structurally can lifting, control sighting distance and visual angle etc.The technical scheme of multi-function health-care desk comprises elevating mechanism, sighting distance governor motion and bookshelf.Elevating mechanism is regulate desk high and low, to adapt to different height students' needs, concrete structure is as follows: desktop is fixed on the U type frame of two symmetries, U type frame has been installed on the support of table leg supporting role, and can upper and lower displacement on support (lifting) to regulate the high and low of desk, it is fixing by the through hole bolting on the corresponding support of the round on the U type frame.The sighting distance governor motion force the student reading, when writing with the suitable distance of desktop maintenance, concrete structure is as follows: desktop near student shirtfront one side (front portion of desktop) fix one straight up position-limited rack, horizontal limit stick be installed in this go up and can upper and lower displacement to regulate the height of limit stick and desktop, it is fixing by the through hole bolting on the correspondence of the round on the vertical spacing chi position-limited rack.This mechanism can rectify sitting posture, prevents to lie prostrate, and makes backbone keep the natural torsion state, and prevention is bow-backed.Can also be on position-limited rack and spacing chi calibrate, all ages and classes, height student's sighting distance is provided total, manipulating like this can be more convenient.In addition, limit stick two ends hemispherical, intermediate cylindrical, no corner angle, chin that can the gouge student, safe and reliable.Bookshelf is fixed on the rear portion of desktop, allows books lean on the shelf, and the both sides of spreading out are fixed with iron clamp.The student ad initio walks to the visual angle that footline all can keep basically identical when reading like this, pre-myopia prevention.The box of the bent formation one groove shape in the following front portion of bookshelf waits study stationery for putting pen, makes that desktop is clean and tidy, standard.

When using, lighting can also be set to the darker classroom of minority light or in family.

Nursing chair is configured to by seat plate, backrest and passive chair, supporting multi-function health-care desk uses, have and regulate high and low elevating mechanism, its structure is that the seat plate that has backrest is fixed on the U type frame of two symmetries, U type frame is installed on the chair frame, and can be on the chair frame upper and lower displacement high and low to regulate, it is fixing by the through hole bolting on the corresponding chair frame of the round on the U type frame.

The utility model is several health cares of collection and renewal product all over the body.That is: (one) different heights, lifting arbitrarily; (2) limit control sighting distance, pre-myopia prevention; (3) inclination bookshelf, optimal viewing angle; (4) adjustable lamp light, good illumination; (5) rectify sitting posture, prevent hunchback.In addition, because desk and chair adopts square tube steelframe U-shaped structure, all connect with holding screw, so structure is firm, applicability is strong have, and characteristics such as manufactures, installation and removal, packing and transportation very make things convenient for.
