The telescopic guide rail comprises a first guide rail body and a second guide rail body, and a first containing cavity is formed in the second guide rail body; the first guide rail is arranged in the first containing cavity in a penetrating mode, and the first guide rail can stretch out of or retract into the first containing cavity. A first guide groove and a second guide groove are respectively formed in the first guide rail and the second guide rail along the length direction, and the first guide groove and the second guide groove are arranged in parallel; when the first guide rail extends out of the first accommodating cavity, the first guide groove is connected with the second guide groove; the telescopic guide rail further comprises a jacking device, the jacking device is installed at the front end of the second guide rail, and the jacking device is configured to push the first guide rail to ascend when the first guide rail extends out of the first containing cavity, so that the first guide groove and the second guide groove are aligned to pass through a nested structure composed of the first guide rail and the second guide rail. And the folding chair meets the use requirements, is convenient to adjust and use, can be retracted when not in use, reduces the occupied space and is high in portability.
本发明公开了一种伸缩式导轨及其伸缩方法,其中包括:第一导轨和第二导轨,第二导轨上形成有第一容纳腔;第一导轨穿设在第一容纳腔内,且第一导轨能够伸出或收回至第一容纳腔内;第一导轨和第二导轨上沿长度方向分别形成有第一导槽和第二导槽,第一导槽与第二导槽平行设置;第一导轨伸出所述第一容纳腔时,第一导槽与所述第二导槽相衔接;还包括顶升装置,顶升装置安装在第二导轨的前端,顶升装置被配置为当第一导轨伸出所述第一容纳腔时,推动第一导轨上升,使第一导槽与第二导槽相对齐通过第一导轨和第二导轨组成的嵌套式结构,伸缩式导轨在使用时,能够延长,满足使用需求,调节和使用方便,在不使用时,能够收缩,减小占用空间、便携性高。
