Swingable pulley structure and sliding door
The invention provides a swingable pulley structure. The swingable pulley structure comprises a pulley base, a front pulley and a rear pulley; the front pulley and the rear pulley are arranged on the pulley base; the pulley base is provided with a front part, a middle part and a rear part; a front connecting shaft is arranged between the front part and the middle part; the front part rotates relative to the middle part; a rear connecting shaft is arranged between the rear part and the middle part; the rear part rotates relative to the middle part; the front pulley is arranged on the front part; and the rear pulley is arranged on the rear part. The pulleys hook a buffer when encountering rail deformation or door closing and opening, so that the door can be kept in a vertical state. The front part and the front pulley return to be horizontal, the rear pulley can rotate relative to the center line of the middle part and the center line of the rear connecting shaft after encountering rail deformation so that the rear pulley can adapt to rail deformation, the swingable pulleys swing through the shafts, and the door is kept in a vertical state and is smooth and light all the time.
本发明提出一种可摆动滑轮结构，包括滑轮座以及设置在滑轮座上的前滑轮和后滑轮，所述滑轮座设置有前部、中部以及后部，该前部和中部之间设置有前连接轴，所述前部相对中部转动，所述后部和中部之间设置有后连接轴，所述后部相对中部转动，所述前滑轮设置在前部上，所述后滑轮设置在后部上，滑轮在，遇到轨道变形或者关门开门时勾到缓冲器，门能保持垂直的状态。前部和前轮恢复水平，后轮遇到轨道变形后部和轮也会相对中部和后连接轴的中心线转动从而使得后轮能够轨道变形，可摆动滑轮通过轴来摆动滑轮，使门始终保持垂直的状态和畅顺轻盈。
