Problems solved by technology
[0007] In order to solve the above technical problems, the present invention provides a horizontally deployable motorized curtain system to solve the existing problem that the existing device is prone to be contaminated with more dust on the curtain after a period of use, and the dust needs to be cleaned manually , It takes a lot of time and effort, and it is impossible to automatically realize the linkage cleaning of the dust on the curtain during the process of rolling and unfolding the curtain through structural improvement; moreover, when the existing device is fixed on the wall, due to the expansion bolts being distorted Afterwards, it will not be able to achieve fixation, and the adjustment of the position of the fixing seat cannot be realized through structural improvement to avoid the above problems, and the problem of elastic anti-loosening of the fastening bolts at the fixing seat cannot be realized.

The invention provides an electric curtain system capable of being horizontally unfolded, relates to the technical field of projection equipment, and solves the problem that linkage cleaning of dust on a curtain cannot be automatically realized in the curtain rolling and unfolding process through structural improvement, the position of a fixing base cannot be adjusted through structural improvement to avoid the problems, and elastic looseness prevention of a fastening bolt at the position of the fixing base cannot be achieved. The electric curtain system capable of being horizontally unfoldedcomprises a frame body, wherein four fixing structures are installed on the frame body, and a curtain is installed on the frame body. Due to the fact that a multi-tooth cam makes elastic contact withthe rear end face of the unfolded curtain, the multi-tooth cam forms a continuous stirring structure of the curtain, and dust on the curtain can be cleaned through continuous stirring of the multi-tooth cam when the curtain is rolled up and unfolded.
Description
technical field [0001] The invention belongs to the technical field of projection equipment, and more specifically relates to a horizontally expandable electric screen system. Background technique [0002] Projection screens are used in movies, offices, home theaters, and large conferences. The tools used to display images and video files need to be used in conjunction with a projector; projection screens are also called projection screens, which are generally divided into commercial screens, household screens, and engineering screens. There are many types of screens, which are divided into high, medium, and low. It depends on the occasion. [0003] For example, the application number: the present invention relates to the technical field of projection equipment, especially an electric screen, which includes an electric screen body and an external power supply line. In the electric screen of the present invention, an LED panel light for lighting is installed at the bottom o...
