Description

Technical Field

[0001] The utility model relates to the technical field of projection screens, and more specifically to a remote-controlled electric screen reel box. Background Art

[0002] Projection screens are used in movies, offices, home theaters, large conferences and other occasions to display images and video files. There are many specifications and sizes, and the choice of projection screens for different spaces is also different. For example, if there are a large number of viewers or horizontal viewing, it is advisable to choose a wide-viewing angle and low-gain screen. If the viewing space is narrow and long, it is better to choose a narrow-viewing angle and high-gain screen. At the same time, choosing a screen with appropriate gain will help improve the contrast of the screen, increase the grayscale of the image, make the color brighter, and increase the visibility of the image.

[0003] Most of the existing curtains require a winding device to roll up and place the curtains, but the winding device of the curtain has a complex structure, is inconvenient to operate, has a single function, does not have a cleaning function when rolling up, and does not have a one-way limit function and a one-way limit unlocking function when rolling up.

[0004] After searching, a Chinese patent with publication number CN216310524U discloses a projection screen winding device. The utility model is provided with a cleaning box, a dust collection box, a scraper, and a brush roller. When in use, the one-way limit of the winding roller is released, and the knob is turned to make the winding roller rotate and wind up the screen. The screen is collected into the winding box through the cleaning box. The screen is dusted and rolled up after use by the cooperation between the scraper and the brush roller, and a cleaning and dust removal function is provided while rolling up. The projection screen winding device is convenient and fast to roll up, and the structure is simple and ingenious, and the screen can be cleaned when rolling up.

[0005] However, when the above-mentioned winding device is actually used, the curtain may need to be inspected and replaced after a long period of use. The process of removing the curtain is relatively complicated, which affects the efficiency of replacement. At the same time, the curtain is relatively light and may deviate during the winding process, affecting the stability of the winding. Utility Model Content

[0041] The embodiment of the present application discloses a remote-controlled electric curtain winding box, which specifically comprises a shell 1, and protective covers 2 are fixedly connected to the left and right sides of the shell 1, and motors 3 are fixedly connected inside the two protective covers 2, and the output ends of the two motors 3 are coaxially connected to the clamping shaft 4, and quick connection mechanisms are movably connected inside the two sides of the shell 1;

[0042] The quick connection mechanism includes a pull plate 5, a slider 6 is fixedly connected to the rear side of the pull plate 5, a pull ring 7 is movably connected to the front side of the pull plate 5, a button 8 is fixedly connected to the outer side of the pull plate 5, a first arc-shaped clamping ring 9 is fixedly connected to the rear side of the pull plate 5, two fixed columns 10 are fixedly connected to the two sides of the inside of the shell 1, and the front ends of the two fixed columns 10 are fixedly connected to the second fixed columns 11. The two first arc-shaped clamping rings 9 and the fixed columns 10 are movably connected with a plurality of balls 12. The two first arc-shaped clamping rings 9 can be separated from the two second fixed columns 11 under the drive of the two pull plates 5 and the slider 6, so that the rotating rod 14 can be quickly removed from the inside of the shell 1. At the same time, through the plurality of balls 12, the rotating rod 14 can maintain stable rotation between the two first arc-shaped clamping rings 9 and the second fixed columns 11.

[0043] Reference Figure 5 As shown, specifically, a curtain 13 is movably connected to the bottom of the housing 1 , and a rotating rod 14 is fixedly connected to the top of the curtain 13 , so as to facilitate rolling up the curtain 13 .

[0044] Reference Figure 7 As shown, specifically, slide grooves 15 are provided on the outer sides of the left and right ends of the rotating rod 14, and blocks 16 are fixedly connected at both ends of the rotating rod 14. Springs 17 are fixedly connected inside the two blocks 16, and limiting balls 18 are fixedly connected at both ends of the two springs 17. Multiple limiting balls 18 are symmetrically distributed on the outer side of the rotating rod 14, so that the two ends of the rotating rod 14 can be quickly connected to the card shafts 4 at the output ends of the two motors 3.

[0045] Reference Figure 1 As shown, specifically, a bottom rod 19 is fixedly connected to the bottom of the curtain 13, and both ends of the bottom rod 19 are fixedly connected to iron blocks 20, so that the curtain 13 remains stable during the rolling process.

[0046] Reference Figure 6 As shown, specifically, electromagnets 21 are fixedly connected to both sides of the bottom of the shell 1, a cleaning roller 22 is movably connected to the bottom side of the shell 1, a scraper 23 is fixedly connected to the bottom of the shell 1, three fans 24 are fixedly connected to the front side of the shell 1, and two filters 25 are fixedly connected to the front side of the shell 1, which can clean the dust on the surface of the curtain 13.

[0047] The working principle of the utility model is as follows: when the curtain is rolled up by the remote control curtain roll-up box, the motor 3 inside the two protective covers 2 drives the rotating rod 14 to rotate through the two clamping shafts 4, and the rotating rod 14 drives the curtain 13 to roll up on the outside of the rotating rod 14 during the rotation process. When the curtain 13 is rolled into the inside of the outer shell 1, the scraper 23 performs the initial cleaning of the front surface of the curtain to scrape off the dust from the surface of the curtain, and then the cleaning roller 22 performs the second cleaning of the surface of the curtain to keep the surface of the curtain clean, and then the dust inside the outer shell 1 is discharged through three fans 24, and the two filters 25 prevent the external dust from being sucked into the inside of the outer shell 1, and then when the curtain is completely rolled into the outside of the rotating rod 14, the bottom of the curtain 13 The iron blocks 20 on both sides of the bottom rod 19 are adsorbed by the two electromagnets 21 at the bottom of the shell 1, so that the bottom rod 19, the iron blocks 20 and the bottom of the shell 1 are kept fixed. When the curtain is disassembled for replacement and maintenance, the two buttons 8 are first pressed to allow the two pull plates 5 and the slider 6 to slide on the inner wall of the shell 1, and then the first arc-shaped snap rings 9 on the rear sides of the two pull plates 5 are pulled by the two pull rings 7 to separate the two first arc-shaped snap rings 9 and the second fixing columns 11, so that the rotating rod 14 and the first arc-shaped snap rings 9 and the second fixing columns 11 on both sides can be separated, and then the two electromagnets 21 are turned off to separate the two iron blocks 20 and the electromagnets 21, so that the curtain 13 and the rotating rod 14 can be quickly removed from the shell 1 for subsequent replacement and maintenance.
