Abstract
Provided is a telescopic rail, comprising a first rail and a second rail slidably arranged relative to each other, two rotating wheels, a belt, a first and a second traction block. When the rail is put into use, loosen the first and the second fixing device to release the belt from the first and the second traction block, then slide the first and the second rail relative to each other till the total length of the rails is qualified for the installation requirement, then tighten the first and the second fixing device to grip the belt by the first and the second traction block, after that cut off the surplus of belt, thus the length of the telescopic rail could be adjusted on-site without preparatory measurements and customizations, which decreases the workload for measurements and improves the efficiency for installation.
