[0023] The present invention will now be described in further detail with reference to the accompanying drawings. Example

[0024] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a multifunctional folding auditorium chair, combined with the attached... Figure 1 It includes a seat, which is assembled by multiple movable support rods to achieve the retractability of the seat, and a canvas pad 11 is connected to the top of the seat;

[0025] Combined with appendix Figure 1-2 The seat also includes a slide cylinder 6 located at the center, and four sets of vertically placed telescopic rods in an X-shape. The telescopic rods are distributed around the slide cylinder 6. The top ends of two adjacent sets of telescopic rods are rotatably connected to an upper connecting plate 10, and the bottom ends of two adjacent sets of telescopic rods are rotatably connected to a lower connecting plate 14. The telescopic rod is composed of two support rods 13 that are rotatably connected to each other at their centers. The two ends of the support rods 13 are rotatably connected to the upper connecting plate 10 and the lower connecting plate 14, respectively.

[0026] The X-shaped telescopic rod, with its two support rods 13 rotating relative to each other to change its tilt shape, can exhibit the function of retracting and extending. The four sets of telescopic rods serve as the side support of the seat. When the ends of the telescopic rods move closer to or further away from the center of the seat, the seat can be tightened into a relatively concentrated state or unfolded into a square support structure with a certain load-bearing area. When unfolded, the canvas pad 11 on top is also fully stretched to form the seat cushion, which directly contacts the human buttocks. The cushion is made of coarse canvas, which can effectively support the human body and prevent excessive sinking. On the other hand, the fabric is easy to fold and can accommodate the telescopic changes of the seat frame structure.

[0027] Combined with appendix Figure 2-4 The top of the sliding cylinder 6 is slidably connected to a sliding column 7, and the top of the sliding column 7 and the upper connecting plate 10 are connected together by a support rod 8 and a support rod 9 whose ends are rotatably connected to each other.

[0028] The part consisting of support rod 1 8 and support rod 2 9 connects the telescopic frame and the slide cylinder 6. On the other hand, after the seat is fully extended, in order to prevent the canvas mat 11 from sinking too much under the weight of the human body, support rod 1 8 and support rod 2 9 located not far below the canvas mat 11 are a bottom support measure.

[0029] Combined with appendix Figure 1-2 The upper connecting plate 10 has a buckle groove, and the canvas pad 11 is connected to a snap fastener 12 that can be installed on the upper connecting plate 10 by snapping into the buckle groove;

[0030] The lower connecting plate 14 is equipped with casters 15 to facilitate the movement of one end of the seat during the unfolding process.

[0031] After retracting, the bottom of the concentrated seat rod structure is a certain distance from the ground. If there is no distance between them, the resistance when pulling the seat out will be greater, which may also cause scratches to the auditorium floor.

[0032] One end of the suspended seat is not easy to maintain balance on the ground, so a caster wheel 15 is installed on the lower connecting plate 14 to fill the gap, stabilize the seat, and protect the auditorium floor during the seat's unfolding and retraction. Example

[0033] Combined with appendix Figure 1-3 The seat is rotatably connected to a storage box 1 buried in the ground. The seat rotates within one end of the storage box 1 to achieve the function of being put away and put away on the auditorium floor.

[0034] Combined with appendix Figure 4-5 A support block 5 is connected below the slide cylinder 6. A support shaft 4 is rotatably connected to one end of the storage box 1 on the support block 5. A cover plate 2 is rotatably connected to one side of the top of the storage box 1, which is flush with the floor of the auditorium when closed. A hinge 3 is installed between the storage box 1 and the cover plate 2.

[0035] The centralized seating structure is a relatively compact rod with grooves cut into the ground to install a storage box 1. By rotating, the seats can be folded down and stored underground. When the cover 2 is closed, the seats disappear into the auditorium, and the spacious auditorium can be used for other activities.

[0036] When the seat is taken out, unfolded and used, the cover 2 should be put back on before unfolding the seat, which will not affect the neatness of the ground.

[0037] In practical implementation, when using the seats in the auditorium, lift the cover plate 2, grasp one of the support rods 13, pull out the seat to keep it upright, then close the cover plate 2 again. Next, grasp the two upper connecting plates 10 with both hands and pull them outwards. In this way, the seat will slowly open up to form a square support. As the support is formed, the top canvas mat 11 will also unfold into a piece of cloth. Finally, people can sit directly on the canvas mat 11. If the seats are to be stored away to free up ample space in the auditorium, the above usage process can be reversed.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
