For this reason; the purpose of this utility model; be on Granted publication number architecture basics, to improve, a kind of thorough correcting sitting postures of energy of the more convenient practicality of operation and posture correcting health desk and chair for study of vision protection well of using is provided for CN2312615Y " a kind of health care desk and chair for study ".

Solution of the present utility model is as follows.It still includes desk and chair, desk comprises the rectangle desktop that is made of frame and intermediate active flat board, be connected in the table body of rectangle desktop below and the table leg that is connected in the height-adjustable multistage latch structure of employing of a body bottom, chair includes the chair back that adopts height-adjustable multistage latch structure and leans on frame, be connected in the chair seat frame and the chair leg that adopt height-adjustable multistage latch structure with chair seat frame link to each other of the chair back by below, frame bottom, the chair back leans on the vertical portion of frame to be fixed with the chair back and leans on, the chair seat frame top is fixed with seat support, the chair back afterwards adopts bearing pin to live mutually respectively by frame two bottom rear and chair seat frame two and is hinged between the side roof parts, being fixed with one on the seat support bottom face, to be enclosed in the chair back outer and leave the position-limited hoop of movable space by the preceding transverse bar middle part of frame, between desk and chair, be connected with the backguy axle of forming by sheath and inner wire of a similar bicycle brake axis, one end of steel wire passes position-limited hoop and links to each other with the preceding transverse bar of the chair back by frame, the utility model feature part structurally is, the frame of desk desktop is made to get up from middle treadmill Open Side Down recessed segment distance and bottom surface resistance envelope and is with the cross section that holds the dull and stereotyped oscilaltion of intermediate active

The shape of shape, be provided with from the bottom surface of the portion recessed down of this frame with it fuses and stretch to several spacing muscle that top and end face flush with the frame end face, offer on the intermediate active flat board of desk with these several suitable sliding sleeves of spacing muscle and coincide together so that the spacing muscle of the dull and stereotyped oscilaltion of intermediate active by perforate, has being respectively of forward and backward two symmetries in the frame recess of forward and backward both sides below the intermediate active flat board

Shape and

The supporting rod that shape is put, two vertical portion of one same side of two supporting rods are passed the perforate of frame recess side respectively and are positioned at outside the side of frame recess, and the termination of these two vertical portion forms to live by bearing pin and frame recess side respectively and is hinged, and two vertical portion of two another same side of supporting rod are also passed the perforate on the frame recess another side respectively and are positioned at outside this side of frame recess, and the centre position of these two vertical portion forms to live by bearing pin and frame recess side respectively and is hinged, and the termination of these two vertical portion then is interconnected and link to each other with a return spring, and the other end of this return spring then joins with the steel wire other end of the aforementioned backguy axle that passes desk table body.

The utility model with said structure is when concrete the use, desk should and chair between keep suitable spacing, the user is sitting on the chair, need human body just sitting and back nestles up the chair back and leans on, drive the position that the chair back is in its preceding transverse bar by the frame rotation, could make the steel wire of the backguy axle inside that links to each other with preceding transverse bar be in tension, so the other end of steel wire drives two supporting rods by return spring and rotates upward around bearing pin, thereby make two supporting rod horizontal supports live in the intermediate active flat board of square table face, could normally learn.Otherwise, the user is in case bow-backed, the chair back is not by just stressing, the chair back will turn forward by frame and make its preceding transverse bar be in down position, and the steel wire in the backguy axle just is in relaxed state so, then two just rotations downwards under the effect of return spring of supporting rods, thereby make the intermediate active flat board lose the support of supporting rod, in the parallel recess that drops to frame, make the user normally not learn, with the announcement of warning.In case it is normal that user's sitting posture recovers, then the intermediate active flat board can be gone up under the drive of backguy axle again automatically, to guarantee normal study.

The utlity model has following advantage and benefit: 1) can make human body keep back straight and upright, thoroughly correct faulty sitting posture, prevent hunchback, and controlled the distance of eyes and desktop, vision protection effectively is so these tables and chairs have really played the health-care effect to the student.2) the intermediate active flat board of desktop is after landing down because of user's abnormal sitting posture, and when sitting posture returned to the tram again by the time, the intermediate active flat board can rise automatically again and reset, and need not hand-reset, is easy to use and saves trouble.3) owing to the dull and stereotyped landing of intermediate active goes down to be parallel landing, and landing distance is less, thus less to the spacial influence of things such as dress school bag in the desk table body, can not cause the inconvenience in the use.4), need so can be suitable for various human body height because table leg, chair leg and the chair back still adopt adjustable for height multistage latch structure by frame.
