The second support members 32 have a retracted state close to the crossbar 1 and an extended state away from the crossbar 1 .
第一支撑件22靠近第一基座21的一端设有第一齿轮23，相邻的第一齿轮23相互啮合使得多个第一支撑件22共同在收起状态和展开状态之间变化，第二支撑件32靠近第二基座31的一端设有第二齿轮33，相邻的第二齿轮33相互啮合使得多个第二支撑件32共同在收起状态和展开状态之间变化。A first gear 23 is provided at one end of the first support member 22 close to the first base 21, and adjacent first gears 23 are meshed with each other so that multiple first support members 22 can change between the retracted state and the deployed state together. A second gear 33 is provided at one end of the second support member 32 close to the second base 31, and adjacent second gears 33 are meshed with each other so that multiple second support members 32 can change between the retracted state and the deployed state together.
第一支撑组件2还包括第一锁定机构24，第一锁定机构24包括凸设于第一基座21的第一按钮241和收容于第一基座21内的第一卡子242。多个第一支撑件22处于展开状态时，第一卡子242使得多个第一支撑件22维持展开状态；需要收起折叠椅框架时，按压第一按钮241可使得多个第一支撑件22移动到收起状态。第二支撑组件3还包括第二锁定机构34，第二锁定机构34包括凸设于第二基座31的第二按钮341和收容于第二基座31内的第二卡子342，多个第二支撑32件处于展开状态时，第二卡子342使得多个第二支撑件32维持展开状态；需要收起折叠椅框架时，按压第二按钮341可使得多个第二支撑件32移动到收起状态。The first support assembly 2 further includes a first locking mechanism 24, which includes a first button 241 protruding from the first base 21 and a first clip 242 received in the first base 21.

由于多个第一支撑件22可联动，多个第二支撑件32可联动，使用本实用新型提供的折叠椅框架时，简化了收起或展开折叠椅框架的操作。Since the plurality of first supporting members 22 can be linked together and the plurality of second supporting members 32 can be linked together, when the folding chair frame provided by the utility model is used, the operation of folding or unfolding the folding chair frame is simplified.
在本实施例中，第一基座21可旋转地连接第一端11，第二基座31可旋转地连接第二端12。横杆靠1近第一端11的位置设有第一止动件111，横杆1靠近第二端12的位置设有第二止动件121，第一基座21包括部分收容横杆1的第一收容槽210，第一收容槽210的侧壁开设有第一通孔2100，第一止动件121收容于第一通孔2100并可在第一通孔2100内滑动，第二基座31包括部分收容横杆1的第二收容槽310，第二收容槽310的侧壁开设有第二通孔3100，第二止动件121收容于第二通孔3100并可在第二通孔3100内滑动。In this embodiment, the first base 21 is rotatably connected to the first end 11, and the second base 31 is rotatably connected to the second end 12. A first stopper 111 is provided at a position of the cross bar 1 close to the first end 11, and a second stopper 121 is provided at a position of the cross bar 1 close to the second end 12. The first base 21 includes a first receiving groove 210 for partially receiving the cross bar 1, a first through hole 2100 is provided on a side wall of the first receiving groove 210, and the first stopper 121 is received in the first through hole 2100 and can slide in the first through hole 2100. The second base 31 includes a second receiving groove 310 for partially receiving the cross bar 1, a second through hole 3100 is provided on a side wall of the second receiving groove 310, and the second stopper 121 is received in the second through hole 3100 and can slide in the second through hole 3100.
利用第一止动件111在第一通孔2100内的滑动，或利用第二止动件121在第二通孔3100内的滑动，可以使第一基座21相对横杆旋转，或使第二基座31相对横杆旋转，这样也同时带动了第一支撑件22或第二支撑件32旋转，使得第一支撑件22和第二支撑件32错开，让第一支撑件22和第二支撑件32在收起状态下均大致平行于横杆1，能够减小折叠椅框架的体积，便于收纳。可以理解，虽然本实施例中横杆1同时具有第一止动件111和第二止动件121，但只有第一止动件111或只有第二止动件121，仍能实现第一支撑件22和第二支撑件32的错开。By sliding the first stopper 111 in the first through hole 2100, or by sliding the second stopper 121 in the second through hole 3100, the first base 21 can be rotated relative to the crossbar, or the second base 31 can be rotated relative to the crossbar, which also drives the first support member 22 or the second support member 32 to rotate, so that the first support member 22 and the second support member 32 are staggered, so that the first support member 22 and the second support member 32 are roughly parallel to the crossbar 1 in the folded state, which can reduce the volume of the folding chair frame and facilitate storage. It can be understood that although the crossbar 1 in this embodiment has both the first stopper 111 and the second stopper 121, only the first stopper 111 or only the second stopper 121 can still achieve the staggering of the first support member 22 and the second support member 32.
在本实施例中，第一支撑件22包括两个第一支撑臂221和两个第一支撑腿222，第二支撑件32包括两个第二支撑臂321和两个第二支撑腿322，第一支撑臂221和第二支撑臂321可伸缩。优选地，收缩状态的第一支撑臂221的长度等于第一支撑腿222的长度，收缩状态的第二支撑臂321的长度等于第二支撑腿322的长度。在伸长状态下，两个第一支撑臂221中的一个的长度大于另一个的长度，两个第二支撑臂321中的一个的长度大于另一个的长度。可以理解，支撑腿用于设置在地面等支撑面以使折叠椅框架稳定，支撑臂用于撑起座椅布以形成折叠椅的座椅部分供人乘坐，较长的支撑臂可作为座椅的靠背部分的支撑。为了使得使用者乘坐时感觉舒适，四个第一支撑件22在垂直于横杆1的平面上的夹角并不时90°，因此本实施例中，在两个第一齿轮23之间还增加了辅助齿轮以确保多个第一齿轮23协同运动。In this embodiment, the first support member 22 includes two first support arms 221 and two first support legs 222, and the second support member 32 includes two second support arms 321 and two second support legs 322. The first support arm 221 and the second support arm 321 are retractable. Preferably, the length of the first support arm 221 in the retracted state is equal to the length of the first support leg 222, and the length of the second support arm 321 in the retracted state is equal to the length of the second support leg 322. In the extended state, the length of one of the two first support arms 221 is greater than the length of the other, and the length of one of the two second support arms 321 is greater than the length of the other. It can be understood that the support legs are used to be set on a support surface such as the ground to stabilize the folding chair frame, the support arms are used to prop up the seat cloth to form the seat part of the folding chair for people to sit on, and the longer support arms can be used as a support for the backrest part of the seat. In order to make the user feel comfortable when sitting, the angle between the four first support members 22 on the plane perpendicular to the crossbar 1 is not always 90°, so in this embodiment, an auxiliary gear is also added between the two first gears 23 to ensure the coordinated movement of multiple first gears 23.
本实用新型提供的折叠椅框架包括：横杆，其包括第一端和第二端；设置于第一端的第一支撑组件，其包括连接第一端的第一基座和多个枢接于第一基座的第一支撑件，第一支撑件具有靠近横杆的收起状态和远离横杆的展开状态；和设置于第二端的第二支撑组件，其包括连接第二端的第二基座和多个枢接于第二基座的第二支撑件，第二支撑件具有靠近横杆的收起状态和远离横杆的展开状态，第一支撑件靠近第一基座的一端设有第一齿轮，相邻的第一齿轮相互啮合使得多个第一支撑件共同在收起状态和展开状态之间变化，第二支撑件靠近第二基座的一端设有第二齿轮，相邻的第二齿轮相互啮合使得多个第二支撑件共同在收起状态和展开状态之间变化。由于多个第一支撑件和多个第二支撑件可分别联动，简化了收起或展开折叠椅框架的操作。The folding chair frame provided by the utility model comprises: a crossbar, which comprises a first end and a second end; a first support assembly arranged at the first end, which comprises a first base connected to the first end and a plurality of first support members pivoted to the first base, the first support member having a stowed state close to the crossbar and an unfolded state away from the crossbar; and a second support assembly arranged at the second end, which comprises a second base connected to the second end and a plurality of second support members pivoted to the second base, the second support member having a stowed state close to the crossbar and an unfolded state away from the crossbar, a first gear is provided at one end of the first support member close to the first base, adjacent first gears mesh with each other so that the plurality of first support members change between the stowed state and the unfolded state together, and a second gear is provided at one end of the second support member close to the second base, adjacent second gears mesh with each other so that the plurality of second support members change between the stowed state and the unfolded state together. Since the plurality of first support members and the plurality of second support members can be linked respectively, the operation of stowing or unfolding the folding chair frame is simplified.
