[0031] like Figure 1-3 As shown, according to another embodiment of the utility model, the desk for correcting sitting posture, preferably, the cross-sectional structure of the table frame 1 along the horizontal direction is U-shaped, the table board 2 is fixedly installed between two opposite side walls of the table frame 1, and two chair legs 5 of one support member and a plurality of magnetic blocks 9 are fixedly installed on the outer side of the horizontal section side wall of the table frame 1; a plurality of first storage compartments 11 are vertically and continuously provided on the table frame 1, and a plurality of second storage compartments 21 are continuously provided along the length direction of one edge of the upper part of the table board 2; wherein a plurality of first storage compartments 11 are arranged along one of the vertical section side walls of the table frame 1, and a plurality of second storage compartments 21 are arranged along the length direction of the edge of the table board 2 close to the horizontal section of the table frame 1; the storage function of the desk is improved by means of the first storage compartments 11 and the second storage compartments 21.

[0032] like Figure 1-3 as well as Figure 5-6As shown, according to another embodiment of the utility model, the desk for correcting sitting posture, preferably, the side wall of the horizontal section of the table frame 1 is provided with a through hole 12, the through hole 12 is located on the rotation track of the seat surface 4, and the side wall of the horizontal section of the table frame 1 is fixedly installed with a mounting groove 7, the mounting groove 7 is located between the two opposite side walls of the table frame 1 and covers the through hole 12, and a waist support is rotatably installed between the mounting groove 7 and the inner and outer sides of the through hole 12; the waist support includes a stopper 8 rotatably arranged between the mounting groove 7 and the inner and outer sides of the through hole 12, and the stopper 8 is connected to the seat body 1 by two rotating shafts 81. A pair of pairs are connected to the two inner walls of the mounting groove 7 for rotation. Each rotating shaft 81 is sleeved with a torsion spring 82, and the torsion spring 82 is elastically connected between the two side walls of the mounting groove 7 and the stopper 8 facing each other; when the students are in class, the chair surface 4 is opened to disengage the magnetic block 9 on it from the magnetic block 9 on the side wall of the table frame 1, and then the chair legs 5 and the connecting rod 6 are rotated to drive the chair surface 4 to rotate and unfold the seat. At this time, due to the elastic effect of the torsion spring 82, the stopper 8 pops out of the mounting groove 7 and the through hole 12, which can support the student's waist and ensure that the student's spine and waist have a good posture and comfort.

[0033] like Figure 1-4 As shown, according to another embodiment of the utility model, the desk for correcting sitting posture, preferably, also includes a correction component, which includes a connecting end and a correction end, the connecting end is rotatably connected to the side wall of the table top 2 away from the table frame 1, and the connecting end rotates between horizontal and vertical directions, the correction end is vertically fixedly connected to the connecting end, and the correction end is an elastic telescopic structure.

[0034] The connecting end includes a rotating plate 3 which is rotatably connected to the side wall of the table top 2 away from the table frame 1 , and the correcting end is vertically mounted on the side wall of the rotating plate 3 close to the upper part of the table top 2 .

[0035] The correction end includes a connecting plate 31 and a sliding plate 33. One end of the connecting plate 31 is fixedly connected to the side wall of the rotating plate 3 close to the upper part of the table top 2, and the other end is provided with a sliding groove 32. The groove width of the sliding groove 32 is smaller than the groove bottom width. The sliding plate 33 is slidably arranged between the inner and outer sides of the sliding groove 32. A baffle 34 is fixedly installed at one end of the sliding plate 33 located in the sliding groove 32. The baffle 34 is elastically connected to the groove bottom of the sliding groove 32 by a spring 35, so that the total length of the sliding plate 33 and the connecting plate 31 is adjustable.

[0036] When students are in class, they rotate the rotating plate 3 to a horizontal state. At this time, the connecting plate 31 and the sliding plate 33 are arranged vertically. The connecting plate 31 and the sliding plate 33 can effectively prevent students from leaning forward during reading and writing, thereby protecting their eyesight. At the same time, since the sliding plate 33 is slidably arranged between the inner and outer sides of the connecting plate 31, the total length of the sliding plate 33 and the connecting plate 31 is adjustable, which can be used by students of different heights.
