Pulley block capable of adjusting angles of bearing wheels according to arc tracks with different radii
The invention discloses a pulley block capable of adjusting the angles of bearing wheels according to arc tracks with different radii. The pulley block capable of adjusting the angles of the bearing wheels according to the arc tracks with different radii comprises a bearing wheel fixing plate, a plurality of bearing wheel assemblies, a plurality of rotary hinge pins and a plurality of locking screws, wherein each bearing wheel assembly comprises a fixed shaft and the corresponding bearing wheel which can be installed at one end of the fixed shaft in a rotary mode, a first through hole and a first threaded hole are formed in each fixed shaft, a plurality of bearing wheel assembly installation parts are arranged on the bearing wheel fixing plate, second threaded holes and second through holes are formed in the portions, corresponding to the first through holes and the first threaded holes, of the bearing wheel assembly installation parts, the end face of each second through hole is in an arc shape, each rotary hinge pin penetrates through the corresponding first through hole from the space below and then is locked on the corresponding second threaded hole, and each locking screw penetrates through the corresponding second through hole from the space above and then is locked on the corresponding first threaded hole. According to the pulley block capable of adjusting the angles of the bearing wheels according to the arc tracks with different radii, squeezing and friction between the inner side faces of the bearing wheels and the arc tracks are avoided, a door leaf can operate smoothly, and noise generated when the door leaf operates is lowered.
