A telescopic curtain guide rail includes an inner rail, an outer rail and a transmission unit. The inner rail is embedded in the outer rail, the transmission unit includes a driving wheel connected with a motor, a driven wheel, two fixed pulleys and a conveyor belt. The driving wheel and the driven wheel are located at two ends of the curtain guide rail, the two fixed pulleys are respectively located at other ends of the inner rail and outer rail. The driving wheel and one fixed pulley are located at two ends of the inner rail or outer rail, the conveyor belt is wound on the driving wheel, the driven wheel and the two fixed pulleys. A telescopic operation of the curtain guide rail can change positions of the two fixed pulleys simultaneously, and the curtain guide rail is simple to use and has a small occupied area.

A rolling curtain mounting housing and an electric rolling curtain are provided. The rolling curtain mounting housing includes a housing body, the housing body is disposed with an accumulator compartment, the accumulator compartment is disposed with an accumulator placement opening. The rolling curtain mounting housing is further disposed with a cover plate, the cover plate is configured to close the accumulator placement opening. The housing body includes an accumulator installation part and a housing extension part connected with each other, the housing extension extends outwards relative to the accumulator installation part, the accumulator installation part is disposed with the accumulator compartment. The cover plate further covers a side surface of the housing extension part on a same side as the accumulator placement opening when the cover plate closes the accumulator placement opening. The provided electric rolling curtain is more convenient to replace the accumulator.

Rolling curtain mounting housing and electric rolling curtain

Provided is an extendable rail, comprising a main rail and an auxiliary rail arranged in parallel with the main rail, the main rail is shifted in longitudinal direction relative to the auxiliary rail, wherein the main rail is configured with a driving wheel and a first reverse wheel; the auxiliary rail is configured with a second reverse wheel, a first guiding wheel and a second guiding wheel arranged inside; a belt loop with fixed length wraps around the driving wheel, the first reverse wheel, the first guiding wheel, the second reverse wheel, the second guiding wheel, and the driving wheel in turn. The total length of the extendable rail can be adjusted according to the practical needs of consumers by adjusting the length of the overlapped area of the main rail and the auxiliary rail, which provides easy adjustment, high universal applicability and operation performance without size customization.

Extendable rail

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.
