Abstract

The invention discloses a torsion-reeled differential type awning curtain or rolling curtain which comprises an outer pipe, a piece of curtain cloth and a traction rod, wherein the outer pipe is reeled on the outer pipe and spread from the outer pipe, and the traction rod is connected with the lower edge of the curtain cloth, wherein each of the two ends of the outer pipe is provided with a retractor; a guiding device is arranged below each retractor; an inner pipe which can rotate freely in the outer pipe is arranged inside the outer pipe; a tubular motor capable of driving the inner pipe to rotate is arranged inside the inner pipe; the outer wall of the inner pipe is provided with at least one tubular spring for tightening the part between the outer pipe and the curtain cloth; and the tubular spring is indirectly or directly connected with the inner wall of the outer pipe. According to the torsion-reeled differential type awning curtain or rolling curtain, the tubular spring is arranged after being pre-tightened, therefore, when reeling or unreeling is carried out, the tubular spring is in a work state and outputs certain torsion to tighten the part between the outer pipe and the curtain cloth, and the curtain cloth can be conveniently reeled or unreeled smoothly. Therefore, the torsion-reeled differential type awning curtain or rolling curtain can be applied widely as the awning curtain or the rolling curtain.

Description

technical field

[0001] The invention relates to the field of sunshade equipment, in particular to torsion coiling differential speed canopy curtain sunshade equipment and torsion coiling differential speed roller blind sunshade equipment. Background technique

[0002] There are many types of canopy blinds on the market:

[0003] Electric Tension Type Canopy Shade (FTS for short): The motor has a separate brake coil, which can be controlled separately to achieve series operation. The "Puzhu" motor acts as a brake during the series operation. The electronic control box outputs an adjustable voltage and short-circuits the two coils of the motor. The voltage range is 40V~130VAC, which can be controlled by an adjustable potentiometer. Running, the series moves forward. At this time, the auxiliary motor brake is released, but a reverse pulling force is generated to balance the series. After the stop command is used or the running reaches the limit, the system stops, and the final...
