Technical Problem

[0002]折叠椅作为一种常见的便携式座椅，其核心优势在于通过巧妙的铰接结构设计，实现了使用状态的展开与闲置状态的折叠，有效解决了固定式座椅占用空间巨大的问题，因此在家庭、会议室、场馆等场合得到广泛应用，然而，现有的大多数常规折叠椅在设计上仅侧重于实现单个椅子的折叠功能，其折叠后的形态往往结构松散、重心不稳，当大量此类折叠椅被集中收纳时，虽然单个体积减小，但多个独立折叠的椅子之间缺乏有效的互锁或连接机制，导致它们无法稳定地并排放置或堆叠，在存储和运输过程中，这些折叠椅极易相互滑动、挤压甚至倾倒，不仅难以整理整齐、占用空间依然较大，还可能需要额外的捆绑固定，反而增加了收纳的复杂性和管理成本，因此，如何使折叠椅在保持个体折叠优势的基础上，进一步实现规模化后的稳定、紧凑收纳，已成为本领域一个急需改进的实际问题

Benefits of technology

本实用新型通过将折叠椅支架设计为铰接的前椅腿和后椅腿，并在座板下方设置支撑条与固定于支架前端的支撑板上的卡接槽相互嵌合，同时在座板左侧设置圆形转动轴与支架上的圆形转动孔适配，实现了座板的稳定承托和顺畅翻转折叠功能；支撑脚组件与螺纹限位组件的配合进一步增强了折叠状态下的结构稳定性和定位可靠性；尤其值得强调的是，该结构使得多个折叠椅在收纳时能够通过前后座椅的座板与靠背相互插设形成稳定连接，实现紧凑、整齐且稳固的纵向堆叠排放，极大节省了存储和运输空间，特别适用于会场、教室等需大量使用和频繁收纳椅子的场合，显著提高了收纳效率与空间利用率，具有突出的实用性和经济性。

Abstract

The application relates to a folding chair which comprises a folding chair support, the upper end outer surface of the folding chair support is provided with a backrest, the front end outer surface of the folding chair support is provided with a seat plate, the lower end outer surface of the seat plate is provided with a supporting strip, and the front end outer surface of the folding chair support is fixedly connected with a supporting plate. The folding chair support is designed as a hinged front chair leg and a rear chair leg, the supporting strip under the seat plate is embedded in a clamping groove on the supporting plate fixed to the front end of the support, meanwhile, a circular rotating shaft on the left side of the seat plate is matched with a circular rotating hole on the support, so that the stable supporting and smooth overturning and folding functions of the seat plate are realized; the cooperation of the supporting foot assembly and the threaded limiting assembly further enhances the structural stability and positioning reliability in the folding state; especially, the structure enables multiple folding chairs to be stably connected by the seat plates and the backrests of the front and rear seats when being stored.
