Abstract

Provided is an energy-saving roller shutter which is convenient to mount, comprising a roller shutter body (1) with a reel pipe, wherein a positioning sleeve (41) embedded in the reel pipe (2) and a retractable fixing assembly (4) located in the positioning sleeve (41) are arranged on at least one end of the roller shutter body; the positioning sleeve (41) is fixedly connected to the reel pipe (2); the positioning sleeve (41) and the retractable fixing assembly (4) can rotate in a relative manner; the retractable fixing assembly (4) comprises a self-locking retractable mechanism and a retaining plug assembly for pressurizing a wall surface to increase a friction force; the reel pipe (2) is internally provided with a booster spring (13); and the booster spring (13) comprises a fixed end and a rotary end for rotating along with the reel pipe (2). The energy-saving roller shutter which is convenient to mount has the beneficial effects that the roller shutter is convenient to mount and dismount; the dismounting and mounting time is shortened, the distance between fixed points at two sides of the roller shutter can be adjusted according to the width of a window, the applicable range of the width of the roller shutter is enlarged, and energy and energy sources are saved, etc.

Abstract

An energy-saving roll-up curtain, comprising a roll-up tube (1) with an electric motor (2) arranged in its interior, a drive wheel (4) being provided on the drive shaft (3) of the electric motor (2) and fixedly connected to the roll-up tube (1). The interior of the roll-up tube (1) is provided with an auxiliary spring (5), comprising a fixed end (6) and a rotating end (7) configured to follow the rotation of the roll-up tube (1). A drive wheel (4) is arranged on the drive shaft (3) of the electric motor (2) and is fixed to the roll-up tube (1), and when the electric motor's (2) drive shaft (3) rotates, the drive wheel (4) drives the roll-up tube (1) to rotate. The invention possesses the beneficial effects of being able to save energy, reduced electric motor energy consumption, and reduced electric motor power requirements.
