Electric curtain with magnetic tension separating device

Abstract

The invention relates to the technical field of audio-visual playback assist, in particular to an electric curtain with a magnetic tension separating device. The electric curtain comprises a storage box and a curtain body, wherein a roll screen rod is transversely arranged in the storage box; and one side of the storage box is fixedly connected with a small low-speed motor for driving the roll screen rod to rotate. According to the electric curtain with the magnetic tension separating device, a front guide block with a built-in guide groove and a front magnetic suction piece is fixed on the front surface of the curtain body, a rear guide block with a built-in bump and a rear magnetic suction piece is fixed at the corresponding position on the reverse surface, the bump at the rear side is inserted into the guide groove in the corresponding position while the curtain body is driven to roll through the small low-speed motor and the roll screen rod, and the target of separating adjacent curtain layers is achieved through mutual absorption of the front magnetic suction piece and the rear magnetic suction piece, so that close friction of the curtain body in a stored state is avoided, the service life of the whole curtain body is greatly prolonged, and the possibility that the surface is contaminated by stains and dust is reduced.

Description

technical field [0001] The invention relates to the technical field of audio-visual playback assistance, in particular to an electric curtain with a magnetic tensioning partition device. Background technique [0002] Projection screens are used in movies, offices, home theaters, and large conferences. The tool used to display images and video files needs to be used in conjunction with a projector. Projection screens are also called projection screens. They are generally divided into commercial screens, household screens, and engineering screens. The current projection screen mainly adopts the rolling curtain to drive the screen to roll and store the screen. When the coupon is collected, the surface of the screen will stick together. If things go on like this, it will easily cause the surface of the screen to wear and be contaminated with dust, which will affect the display effect and use. life.
