[0019] 13. Limit plate Detailed Implementation

[0020] like Figure 1 , 2 As shown, the technical solution of this utility model is a dining chair that can be quickly disassembled and assembled, including a backrest 1 and a seat 2. The lower end of the backrest 1 is provided on the upper rear side of the seat 2 through two rotating parts. The rotating parts include a support platform 3, a rotating shaft 4, and a limiting rod 5. The support platform 3 is fixed on the seat 2. The support platform 3 is provided with a hole with a bearing for the rotating shaft 4 to rotate. The inner end of the rotating shaft 4 is rotatably provided in the hole with the bearing, and its outer end is connected to the lower end of the backrest 1 through a connecting short plate 6. A limiting rod 5 is provided on the outer rear side of the connecting short plate 6 of each rotating part.

[0021] The chair surface 2 has a groove and a limiting post on its left outer side, and a long strip protrusion 7 and a limiting groove 8 that cooperate with the groove and the limiting post on its right outer side. By cooperating with the groove and the long strip protrusion 7 and the limiting post and the limiting groove 8, it is easy to splice multiple dining chairs into a long bench and improve its stability.

[0022] The lower surface of the chair seat 2 is mounted on the base 9 via four adjustable bodies. Each adjustable body includes a lower adjusting sleeve 10, an upper adjusting rod 11, a screw 12, and a limiting plate 13. The lower end of the lower adjusting sleeve 10 is fixed to the base 9, and the upper end of the lower adjusting sleeve 10 is open. Slide grooves that mate with the limiting plate 13 are provided on both the front and rear sides of the lower adjusting sleeve 10. The lower end of the upper adjusting rod 11 enters through the upper opening of the lower adjusting sleeve 10 and connects to the limiting plate 13. The front and rear ends of the limiting plate 13 slide within the corresponding slide grooves. The lower end of the upper adjusting rod 11 has a threaded hole. The lower adjusting sleeve 10 has multiple through-holes (front and rear). The screw 12 passes through the front adjusting hole, the threaded hole, and the rear adjusting hole and is fixed by a nut. The height of the chair seat 2 can be changed by adjusting the distance between it and the base 9 according to usage; it can also be adjusted during storage to reduce space occupation.

[0023] The lower surface of the base 9 is provided with four anti-tilt components, each including an inclined plate 14 and a mounting sleeve 15. The upper inner end of the inclined plate 14 is provided with the mounting sleeve 15, which is fitted over the fixed platform 16. A magnet is provided between the mounting sleeve 15 and the fixed platform 16. The fixed platform 15 is located on the lower surface of the base 9. The anti-tilt components effectively prevent the dining chair from tilting or veering, improving safety and stability (the positional relationship in the figure is described relative to the user sitting on the dining chair).

[0024] In this embodiment, the upper end of the limiting rod 5 is provided with an inclined surface that cooperates with the connecting short plate 6.

[0025] In this embodiment, each of the aforementioned anti-tilt components is arranged vertically and vertically corresponding to the adjustable body.

[0026] In this embodiment, breathable pads are provided on the front of the chair back 1 and on the seat surface 2.

[0027] In this embodiment, the lower end of the inclined plate 14 is provided with an anti-slip pad.

[0028] The working process and principle of this example: When in use, open and support the backrest 1, and adjust it to the required height using the adjustable parts; when it needs to be assembled into a long bench, the grooves and long protrusions 7 on the outer side of multiple seat surfaces 2, as well as the limiting posts and limiting slots 8, can be spliced ​​together to meet the needs of long benches. When not spliced, light items can be hung on the limiting posts; when it needs to be stored, fold the backrest 1 close to the seat surface 2, and retract the adjustable parts to place the seat surface 2 and the base 9 close together.

[0029] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
