Abstract

The invention belongs to the technical field of door and window hardware fittings, and discloses a pulley assembly which comprises a shell and at least two pulleys. A cavity is formed in the shell, anopening is formed in at least the bottom of the shell, each pulley comprise a wheel body and a wheel axle connected with the wheel body, the pulleys are movably arranged in the cavity, adjusting wheels for adjusting the positions of the pulleys are further arranged in the cavity, and the periphery of each adjusting wheel is circular; the two sides each wheel axle are each correspondingly providedwith one adjusting wheel, the adjusting wheels on the two sides of the wheel axles are in tangential contact with the wheel axles, and the shell is connected with a distance adjusting device for adjusting the distance between the adjusting wheels through extrusion so as to change the positions of the pulleys. The pulley assembly is good in structural reliability, simple in overall product structure, small in number of spare parts and easy to produce and machine.

Description
