Description

Technical Field

[0001] This utility model relates to the field of ceiling silver, specifically a ceiling silver screen that is easy to assemble. Background Technology

[0002] Projection screens, also known as projection displays, are generally categorized into commercial screens, home screens, and project screens. There are many types of screens, ranging from high-end to low-end, depending on the application. Ceiling screens, which are embedded in the ceiling, are primarily used in home theaters or commercial spaces for concealed installation. When retracted, they blend seamlessly with the ceiling, saving space and offering a discreet appearance. However, existing ceiling screens do not allow for automatic surface cleaning, leading to dust and debris buildup that can affect their continued use.

[0003] To address the aforementioned issues, a ceiling screen that is easy to assemble is proposed here. Utility Model Content

An mounting member is provided on the top between the two threaded rods on the same side, and mounting holes are provided on both sides of the top of the two mounting members. The two mounting holes facilitate the fixed installation of the device.

[0009] Preferably, each of the four threaded rods is threaded with two first fastening nuts at the connection points between it and the two mounting parts, and each of the four threaded rods is threaded with two second fastening nuts at the connection points between it and the two fixing parts. The arrangement of the four first fastening nuts and the four second fastening nuts can serve as a limiting function.

[0010] Preferably, fixing holes are provided at the connection points of the two fixing members and the two threaded rods, and at the connection points of the two mounting members and the two threaded rods on both sides, so that the installation of the four threaded rods can be facilitated by the setting of eight fixing holes.

[0011] Preferably, the air inlet of the micro air pump is fixedly connected to an air inlet pipe, and the end of the air inlet pipe away from the micro air pump is fixedly connected to a filter. The filter facilitates the filtration of the air entering the micro air pump.

[0012] Preferably, a motor is fixedly installed at one end of the mounting base, and the output end of the motor extends into the interior of the mounting base and is fixedly connected to one end of the cleaning soft brush. The motor drives the cleaning soft brush to rotate, and the cleaning soft brush cleans the surface of the curtain.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the two mounting holes facilitate the fixed installation of the device on the ceiling, and the height of the screen can be adjusted by adjusting the position of the eight first fastening nuts. The cleaning soft brush is driven by a motor to rotate and clean the surface of the screen. High-pressure gas is generated by energizing a micro air pump and introduced into the diversion pipe through the air outlet pipe. The high-pressure gas is then sprayed out through several jet nozzles, which facilitates further cleaning of the screen surface and prevents dust and foreign objects from adhering to the screen surface, thus affecting the subsequent use of the screen.
