The purpose of this utility model is that a kind of practical, effective standard and control sitting posture will be provided, and money is sat in the study that makes the user can keep correct under automatic situation, the health care piece desk and chair of pre-myopia prevention, control crookback.The combined characteristic of piece desk and chair can be changed, can be deformed into an energy and in a big way, adjust height and backrest slope, the independent seat that can fold, this piece desk and chair has full folder function, and book drawer, bookshelf are complete.

The purpose of this utility model is achieved in that this piece desk and chair is provided with a Posture correction backrest, the backrest bottom is drilled with a plurality of for the adjusting pin-and-hole of adjusting height usefulness, be fixed on the crankle of seat carriage, on this backrest upper end crosspiece the device that links positive appearance band is arranged, there is positive appearance band spacing hole two sides: have two certain elastic force is arranged, adjustable length, the positive appearance band that the termination can link, positive appearance band one end is fixed on the crosspiece of backrest upper end, article two, the both shoulders by the user about positive appearance band divides carry out X type intersection through the oxter behind Posture correction backrest, join before abdomen through spacing hole again, the suitable back two positive appearance bands of length adjustment are linked, user's both shoulders just are controlled on the Posture correction backrest by positive the relative of appearance band nature with the waist abdomen, and positive appearance function is accomplished.

The bottom of Posture correction backrest is taked studless open, when piece desk and chair is out of shape, can move on the coupled axle-pin that is loaded on the seat carriage other end easily, and when adjusting backrest slope, can not be subjected to the obstruction of miscellaneous part, crankle and carriage are that split is manufactured and then carried out fixedly connectedly, useless crankle can be removed when piece desk and chair is out of shape.The interlock pole that piece desk and chair has two sections to link to each other, when the piece desk and chair form, the effect of two sections interlock pole is identical, when distortion the connection of interlock pole upper end with table pole disconnected, interlock pole epimere can effectively be adjusted the gradient of seat back by the position that changes the upper end.Positive appearance band and schoolbag frame are taken off from Posture correction backrest, and the spherical hand rotary nut at Panasonic rotating shaft two ends can be removed book drawer and desktop easily, more than the dismounting and moving of each parts debug wholely, can realize that piece desk and chair is deformed into the purpose of independent seat.

Piece desk and chair is furnished with a book drawer in the middle of being fixed on below the desktop, there is side plate the left and right sides under the book drawer base plate, have the slideway parallel on the biside plate with base plate, desktop can move by before and after slideway is in rotating shaft, adjust the spacing of desktop and Posture correction backrest, the slideway front end has the position to be lower than the longitudinal folding hole of slideway, communicate with slideway, make the rotating shaft two ends enter the lower end in folding hole from slideway, with the distance between this book of increase drawer base plate and the rotating shaft, book drawer base plate obstruction desktop can not withstood in the upper end of leg, and turnover is folded down.

One end of piece desk and chair seat is to use hinged joint to link to each other with carriage, seat can be dug from the rear end, after schoolbag frame taken off, Posture correction backrest just can be turned on the pin of crankle flexibly, because of seat can be dug, can not hinder the flip-flop movement of Posture correction backrest lower end, thereby realize folding of Posture correction backrest and seat, carriage.

Good effect of the present utility model is very tangible: two positive appearance bands can be controlled at user's both shoulders and waist on the Posture correction backrest, its positive appearance effect is visible really, because an end of positive appearance band is manufactured with elastic band, size is shorter, the other end is manufactured with inelastic braces, longer dimension, length can be adjusted.When user's sitting posture is correct, positive appearance band is inoperative, naturally can not bring uncomfortable sensation, because the upper end of positive appearance band is an elastic band, it allows user's short time slight " foul ", this foul can make the elastic band elongation, the user need overcome the pulling force of elastic band retraction, and " foul " time is the president not, and this control has control and not dead advantage, because the elastic band of positive appearance band part is shorter, elastic force is limited, and user's free activity is just limited, can not cause serious " foul ", therefore this control has dynamic but not chaotic advantage, and this positive appearance mode should the person of being to use be taken like a shot, effective, extensively be suitable for.Collapsible schoolbag frame is housed on the adjustment hole of Posture correction backrest, very convenient to student user.
