Because it was originally an open space and there were many participants, this required the primary school students who came to participate in the assembly to bring their own activity chairs, or the activity staff to arrange a sufficient number of chairs to deal with it. Therefore, such chairs must be lightweight and should not take up storage space. Traditional chairs cannot do this perfectly, and there are problems such as heavy weight, difficult to carry after folding, and unreasonable structure and difficulty in taking out.

[0027] The utility model provides a foldable, flat, lightweight and easy-to-store student activity chair, which solves the problems that the existing foldable chairs are relatively heavy and inconvenient to use in schools, and is more lightweight and flatter after being folded, so that it is easy to store and take out for use.
[0028] See also Figure 1 A foldable, flat, lightweight and easy-to-store student activity chair according to one embodiment of the utility model comprises a seat 1, and an axially variable foot 2 and a fixed axial foot 3 are rotatably connected below the left and right ends of the seat 1. The seat 1 is provided with a handle 4 at one end connected to the axially variable foot 2. The handle 4 is, for example, a strip hole opened at the edge of the seat 1, which is integrated with the seat 1 and has a simple and durable structure. A hollow portion 5 is provided in the middle and upper part of the fixed axial foot 3. The hollow portion 5 is, for example, a groove-shaped opening facing upward, which is used to accommodate the axially variable foot 2. The axially variable foot 2 is located in the hollow portion 5. A first limit connector is provided on the axially variable foot 2, and a second limit connector is provided on the fixed axial foot 3. The first limit connector is movably connected to the second limit connector.
[0029] See also Figure 2For example, the first limiting connection member is a variable axis sliding groove 6, which is located on the side of the lower middle part of the axis variable chair foot 2. The second limiting connection member is a limiting shaft 7, such as a cylindrical rotating shaft; the limiting shaft 7 is located inside the hollow part 5, for example, the two ends of the limiting shaft 7 are embedded in the holes on both sides of the groove-shaped hollow part 5 of the fixed axis chair foot 3; and the limiting shaft 7 is matched to penetrate the variable axis sliding groove 6, thereby forming a sliding connection.
[0030] Please also see Figure 3 , Figure 4 When the foldable, flat, lightweight and easy-to-store student activity chair is unfolded, the limit shaft 7 (the second limit connecting member) is exactly located at the upper end of the variable axis sliding groove 6, and the limit is realized by contacting each other. When folding, the limit shaft 7 can slide in the variable axis sliding groove 6. This limiting method allows folding / unfolding to be performed only in this way (the way the limit shaft 7 moves in the variable axis sliding groove 6), and after moving / putting on the ground, it can be automatically locked through the structural design, without manual positioning / installation, and primary school students can also use it easily without any doubts about the folding / unfolding method.
[0031] It is understandable that the first and second limit connecting members are not limited to this. For example, the variable axial sliding groove 6 can also be matched with a limit protrusion (equivalent to only the parts at both ends of the limit axis 7); for example, the axial variable chair foot 2 and the fixed axial chair foot 3 can also optionally adopt a detachable installation connection, plug-in, snap-on connection, stop / lock limit, etc.
[0032] See also Figure 3 Preferably, when the foldable, flat, lightweight and easy-to-store student activity chair is unfolded, the seat 1 is horizontal, and the axis variable chair leg 2 and the fixed axis chair leg 3 cross to form an X shape. The ends of the axis variable chair leg 2 and the fixed axis chair leg 3 both have an inclined surface structure, so that in the unfolded state, the lower end surfaces of the axis variable chair leg 2 and the fixed axis chair leg 3 are horizontal.
[0033] See also Figure 5 , Figure 6 , Figure 7 When the flat, lightweight and easy-to-store student activity chair is in the folded state, the hollow portion 5 accommodates the lower end of the axial variable chair foot 2, and the axial variable chair foot 2 and the fixed axial chair foot 3 are located in the same plane, and the seat 1 is parallel to the axial variable chair foot 2 and the fixed axial chair foot 3, forming a flat structure as a whole.
[0034] Preferably, the upper part of the axis variable chair foot 2 is provided with a first avoidance groove 8, and the upper part of the fixed axis chair foot 3 is provided with a second avoidance groove 9; when the foldable flat, lightweight, and easy-to-store student activity chair is folded, the first avoidance groove 8 and the second avoidance groove 9 are in an L-shaped shape that is flush with each other, and the end of the seat 1 away from the handle 4 is accommodated in the first avoidance groove 8 and the second avoidance groove 9. Furthermore, the thickness design of each component makes it possible that when the foldable flat, lightweight, and easy-to-store student activity chair is folded, the surface of the seat 1 is flush with the surface of the axis variable chair foot 2 and the fixed axis chair foot 3, so that it is closer to a flat plate in the folded state, and is easy to be placed in a narrow space or stacked flat; especially for stacking, it can ensure stability. The existing folding chairs are not flat, but have large bumps or slopes as a whole. If they are stacked up and down, they are easy to collapse. When they are stacked closely horizontally, the adjacent folding chair structures are easy to cross and difficult to separate.
[0035] Preferably, the seat 1, the variable axis foot 2 and the fixed axis foot 3 are all in the shape of a rectangular plate, and more preferably, the edges of the rectangular plate have smooth chamfers. This structure is easy to produce and process, and is thicker and more durable, and is not easy to hurt the human body, so it is particularly suitable for use in scenes such as primary schools.
[0036] See also Figure 8 , Fig. 9 The seat 1 is pivotally connected to the upper end of the axial variable chair foot 2, and the seat 1 is pivotally connected to the upper end of the fixed axial chair foot 3. The connecting shaft seat of the pivot connection is set according to the corresponding structure, and the rotating shaft is passed through the connecting shaft seat, so that the position of the rotating shaft is fixed. Compared with the hinge, the overall structure is stronger and more stable.
[0037] In summary, the foldable, flat, lightweight and easy-to-store student activity chair of the utility model consists of three main components, namely a seat 1 with a portable handle, an axially variable leg 2, and a fixed-axial leg 3; the structural principle of cross-leg folding is utilized; the axis of the top of the axially variable leg 2 and the fixed-axial leg 3 are connected to the seat 1 by a fixed rotating shaft; the structure is stable when unfolded and used, and the axially variable leg and the fixed-axial leg are movably coordinated; during the folding and folding process, the rotating shaft of the middle axis of the fixed-axial leg 3 moves and slides relative to each other along the variable axis sliding groove of the axially variable leg 2, so that the axially variable leg 2 and the fixed-axial leg 3 can be folded and flattened; primary school students can walk while holding the handle on the seat 1; because of the perfect staggered structure of the three components, a completely flat space can be achieved after folding, so when stacking, it is just like stacking storage tablets, which saves space easily and freely.
