Embodiment 1

[0038] Embodiment one of the present invention is a kind of folding desk and chair, as figure 1 -shown in 4, comprise desk 10 and school chair 20, desk 10 comprises desktop 11, desk cabinet 12, table base 13 and desktop support member 14, desk cabinet 12 and desk base 13 are fixedly connected, and desktop is flat plate shape, uses Made of wood or plastic or metal plate, the desk cabinet is a vertical cabinet structure, located on the left or right side of the desk, with a locker 121 inside the cabinet for storing books and bedding, the inside of the desk cabinet 12 A lifting connecting plate 122 is fixed with screws above, and the lifting connecting plate is provided with a plurality of screw holes arranged vertically, and the height of the lifting connecting plate can be adjusted by screws passing through different screw holes, so as to adapt to the needs of students of different heights. Desktop 11 is connected with desk cabinet 12 with desktop hinge 111, and desktop hinge i...

Embodiment 2

[0049] Embodiment two of the present invention is also a kind of folding desk and chair, comprises desk 10 and school chair 20, and school chair is exactly the same as embodiment one, see appendix figure 1 , 2 , the desk 10 is basically the same as the first embodiment, the only difference is that the structural form of the desktop support 14 is a support frame 14 b, such as Figure 5 , 6 As shown, it is hinged with the end of the desktop 11, the support frame is a rectangular structure, and its lower end is provided with a positioning foot 14b1, and the table base 13 is provided with a positioning nest 131 or a positioning groove. When the desktop is in a horizontal position, the positioning foot 14b1 is inserted into the positioning In the nest 131; when the desktop turns to a vertical position around the desktop hinge 111, the support frame 14b turns around the hinge to a position parallel to the desktop, so as to fit the desktop; the support frame is provided with a heigh...

Embodiment 3

[0051] In this embodiment, on the basis of the second embodiment, a crank-link control mechanism is added to control the adjustment of the support frame 14b, so that the operation is more convenient. The crank-link control mechanism includes a control link 14b2 and a control crank 14b3 that are hinged to each other. , the free end of the control link 14b2 is hinged on the support frame, and the free end of the control crank 14b3 is hinged on the table cabinet 12. When the intersection angle between the control link 14b2 and the control crank 14b3 is 180 degrees, the support frame 14b is perpendicular to the desktop, and the desktop is in a horizontal position , when the intersecting angle between the control link 14b2 and the control crank 14b3 is close to 0 degrees, the intersecting angle between the support frame 14b and the table top is also close to 0 degrees, and it fits together with the table top and sags to a vertical position under its own weight, such as Figure 8 , ...

Abstract

The invention discloses a foldable desk and chair. The foldable desk and chair is used for classroom teaching and a siesta, and comprises a desk body and a chair body; the desk body comprises a desktop, a desk cabinet, a desk base and a desktop supporting piece, the desk cabinet is fixedly connected with the desk base, the desk cabinet is arranged on the left side or the right side of the desk body, the desktop is connected with the desk cabinet through a desktop hinge, and the desktop can rotate around the desktop hinge; the chair body comprises a chair frame, a backboard, a seat board, a positioning connecting rod and a pillow or supporting board, and the a chair frame, the backboard, the seat board, the positioning connecting rod and the pillow or supporting board are mutually movably connected. During teaching, the desktop rotates to the horizontal position around the desktop hinge, and the seat board rotates to the horizontal position around a hinge; during the siesta, the desktoprotates to a similar horizontal position around the desktop hinge, the backboard and the seat board or the backboard and the supporting board rotate around the hinge to form the intersection angle ofan obtuse angle for human body lying. According to the foldable desk and chair, on the premise that the occupied space of the desk and chair is not increased, the function that the desk body is usedfor lying is achieved, a comfortable and healthy siesta facility is provided for primary and secondary school students, and the difficult-student-siesta-taking problem that schools and patriarchs aretroubled for a long time is solved.
