[0002] With the development of various display technologies, projection display technology, which can achieve ultra-large display screens, has attracted more and more attention. In order for projection display technology to achieve or exceed the mainstream LCD display technology or organic display technology in the market in terms of display image effects, in addition to high-quality projectors, high-quality optical projection screens are also essential key components. Screens are usually used together with projectors. Existing projection screens can be divided into two categories: easy to carry and fixed installation. Currently, the portable projection screens are usually ground-lifting and bracket-type screens.

The utility model supports the electric telescopic rod by first pushing the supporting plate through a driving member (including but not limited to a micro push rod) before adjusting the height of the audio equipment, so as to avoid excessive fit of the connecting block to one end of the limit shell, thereby preventing mutual limit resistance and difficulty in extension, and at the same time improving the supporting force of the electric telescopic rod, and preventing the rubber pads from colliding with each other and being scratched. When the height of the audio equipment is adjusted, the lifting position can be adjusted, but the position is not limited.

[0025] 3. The utility model closes the sound shell by pulling the cover through the sliding groove and sliding the switch along the connecting rod. It is opened and closed when in use to allow the sound equipment to slide out, and closed when not in use to prevent dust from entering. When closed, the insertion plate fixed at one end of the cover is inserted into the reserved opening reserved in the base, and the elastic pad elastically presses the inside of the reserved opening to limit the cover in the closed state, thereby preventing the sound shell from sliding and opening during transportation or carrying.

The threaded rod 407 is threadedly connected to the connecting block 403. The audio device 405 and the curtain device 2 are placed in the audio shell 3 as a whole, which is convenient to carry and avoids the trouble of secondary assembly. When in use, the micro motor 406 drives the threaded rod 407 to rotate, so that the connecting block 403 slides along the limiting shell 404, and the electric telescopic rod 401 follows the connecting block 403 to adjust the position for extension and retraction, thereby improving the support for the audio device 405. The electric telescopic rod 401 is rotatably connected to the threaded rod 407 and the audio shell 3 through the connecting block 403 and the rotating block 402, respectively, to avoid adjusting the height of the audio device 405, so that the electric telescopic rod 401 is limited to each other and difficult to adjust, and is kept in the middle of the corresponding curtain device 2, thereby improving the comfort of use.

[0036] Reference Figure 2 and Figure 5 A mounting block 5 is fixed at the center of the inner bottom end of the audio shell 3, and a driving member 6 is embedded in the inner wall of the mounting block 5. The power output end of the driving member 6 is connected to a supporting plate 7, and a rubber pad 8 is arranged on the top of the supporting plate 7. The supporting plate 7 forms a telescopic structure between the driving member 6 and the mounting block 5, and the supporting plate 7 is bonded and connected to the rubber pad 8. Before adjusting the height of the audio equipment 405, the supporting plate 7 is first pushed by the driving member 6 (including a micro push rod, but not limited to a micro push rod) to support the electric telescopic rod 401 to avoid excessive fit of the connecting block 403 to one end of the limiting shell 404, thereby causing mutual limiting resistance and difficulty in extension, while increasing the supporting force of the electric telescopic rod 401, and causing scratches due to collisions with each other through the rubber pad 8. When the height of the audio equipment 405 is adjusted, the rising position can be adjusted, but the position is not limited.

[0037] Reference Figure 1 and Figure 6The top of the sound shell 3 is provided with a closing mechanism 9, which includes a connecting rod 903, which is fixed on the top of the inside of the sound shell 3, and the outer wall of the connecting rod 903 is slidably connected with a cover plate 901, and the inner wall of the cover plate 901 is provided with a sliding groove 902 corresponding to the position of the connecting rod 903. The closing mechanism 9 also includes an insert plate 904, which is fixed on one side of the outer wall of the cover plate 901, and the top of the insert plate 904 is connected with an elastic pad 905. The structure of the insert plate 904 is a conical structure, and the insert plate 904 is inserted into the outer wall of the cover plate 901. The plate 904 is bonded to the elastic pad 905, and the cover 901 is pulled through the sliding groove 902 and the sliding switch along the connecting rod 903 to close the audio shell 3. It is opened and closed when in use to allow the audio device 405 to slide out, and closed when not in use to prevent dust from entering. When closed, the insertion plate 904 fixed at one end of the cover 901 is inserted into the reserved opening reserved in the base 1, and at the same time cooperates with the elastic pad 905 to elastically press the inside of the reserved opening, so that the cover 901 is limited in the closed state to prevent sliding during transportation or carrying and opening the audio shell 3.

[0038] The implementation principle of the utility model is as follows: the supporting plate 7 is pushed by the driving member 6 to lift the electric telescopic rod 401, and the rubber pad 8 is cooperated to avoid collision. At the same time, the micro motor 406 embedded in the limit shell 404 works to drive the threaded rod 407 to rotate, thereby pushing the connecting block 403 to slide along the limit shell 404. At the same time, the electric telescopic rod 401 works to support the limit shell 404 by pushing the connecting block 403, and the electric telescopic rod 401 follows the movement of the connecting block 403 to extend and retract to avoid mutual limitation. At the same time, the connecting block 403 is rotatably connected to the electric telescopic rod 401, and the electric telescopic rod 401 is rotatably connected to the audio shell 3 through the rotating block 402, so that the electric telescopic rod 401 can be adjusted according to the audio equipment 40 5 can be supported by the rising angle adjustment shell 404, and the limit shell 404 can stably rotate inside the sound shell 3 through the support shaft 408 to avoid mutual limitation and inability to stretch, so that the sound equipment 405 can adjust the height, and is integrated with the base 1 and the curtain device 2 to avoid the need for secondary connection of cables and installation; the cover plate 901 slides along the connecting rod 903 through the sliding groove 902, thereby closing the switch of the sound shell 3, allowing the sound equipment 405 to pass through the sound shell 3, and the connecting rod 903 and the sliding groove 902 can prevent the cover plate 901 from being separated from the sound shell 3. At the same time, the cover plate 901 is conveniently inserted into the reserved opening of the base 1 after covering through the fixed insertion plate 904, and is elastically pressed by the elastic pad 905, so that the cover plate 901 can cover the sound shell 3.
