[0022] Please refer to the attached Figure 1 -Attached Figure 4 A news dissemination display device comprises a base 1, a display cabinet 2 is fixed on the top surface of the base 1, a switch cover 101 is connected to the front and rear sides of the display cabinet 2 through hinges, the switch cover 101 is locked with the display cabinet 2 through a buckle, a display hole 102 is opened on one side of the switch cover 101 located on the front side of the display cabinet 2, a display board 3 is arranged inside the display cabinet 2, an iron sheet is fixed to one side of the display board 3, a cleaning component is arranged inside the display cabinet 2, a supporting mechanism is arranged below the display board 3, the cleaning component comprises a winding roller 103 rotatably connected to the two left corners of the top surface of the base 1, a transparent film 104 is rolled up on the outer wall of the winding roller 103, and the transparent film 104 is made of PVC material, and the two right corners of the top surface of the base 1 are rotatably connected to the limiting roller 105, and the transparent film 104 passes through the two limiting rollers 105.

[0023] In the embodiment, gears are fixed to the tops of the two winding rollers 103, and the two gears are driven by toothed belt meshing. A driving motor is fixed to the top surface of the display cabinet 2, and the output shaft of the driving motor passes through and extends to the interior of the display cabinet 2. The output shaft of the driving motor is fixed to the gear of the winding roller 103 near the left front corner of the display cabinet 2. The four corners of the bottom surface of the display cabinet 2 are detachably fixed with arc plates 201 by bolts, and two cleaning brushes 202 are fixed to the inner wall of the arc plate 201. A cleaning sponge 203 is also fixed to the inner wall of the arc plate 201 between the two cleaning brushes 202. The cleaning brushes 202 and the cleaning sponge 203 are both tightly fitted to the outer wall of the transparent film 104. By arranging a retractable transparent film 104 inside the display cabinet 2, when the transparent film 104 is contaminated and the news poster on the display cabinet 2 is unclear, the transparent film 104 is reeled up by the reeling roller 103, so that the part of the transparent film 104 located at the display hole 102 starts to move, so that the clean part of the transparent film 104 moves to the display hole 102, and at the same time, the contaminated part of the transparent film 104 moves on the cleaning brush 202 and the cleaning sponge 203, so that the cleaning brush 202 and the cleaning sponge 203 clean the transparent film 104, thereby effectively avoiding that when the cleaning device is cleaned, the cleaning mechanism will block the line of sight of pedestrians to a certain extent, affecting pedestrians from viewing the news posters.

[0024] In the embodiment, a plurality of magnetic strips 301 are magnetically attracted to one side of the display board 3, a plastic plate 302 is fixed to one side of the magnetic strip 301, and the plastic plate 302 is made of transparent plastic. By using a plurality of magnetic strips 301 in conjunction with the plastic plate 302, it is convenient to clamp the news poster on the display board 3, and the position of the magnetic strip 301 can be changed arbitrarily, so that the display board 3 can fix news posters of different sizes.

[0025] In the embodiment, the support mechanism includes a hidden groove 303 provided on the bottom surface of the display board 3, the inner top surface of the hidden groove 303 is rotatably connected to the first link rod 304, one end of the first link rod 304 is fixed with a directional wheel 305, the top surface of the first link rod 304 is rotatably connected to the second link rod 306, the inner top surface of the hidden groove 303 is also rotatably connected to a rebound sleeve rod 307, two limit rods 308 are fixed inside the rebound sleeve rod 307, the outer wall of the limit rod 308 is movably sleeved with a spring, the second link rod 306 is inserted into the inner part of the rebound sleeve rod 307, and the limit rod 308 and the second link rod 306 are inserted into the inner part of the rebound sleeve rod 307. When in use, when the display board 3 is pulled out from the display cabinet 2, the first link rod 304 loses the restriction of the display cabinet 2, the spring of the limit rod 308 rebounds and pushes the second link rod 306. Since the first link rod 304 is rotatably connected to the hidden groove 303, the second link rod 306 is rotatably connected to the first link rod 304, and the rebound sleeve rod 307 is rotatably connected to the hidden groove 303, when the second link rod 306 is pushed by the spring elastic force, the first link rod 304 is driven to rotate until the first link rod 304 is perpendicular to the display board 3, thereby supporting the bottom surface of the display board 3.

[0026] In an embodiment, a collecting hole 106 is provided on one side of the base 1, a collecting box 107 is inserted into the collecting hole 106, and a falling hole 108 is provided on the top surface of the base 1, which is connected to the collecting hole 106. Through the setting and use of the falling hole 108 and the collecting box 107, the dust scraped off the cleaning brush 202 and the cleaning sponge 203 can be collected into the collecting box 107.

[0027] In the embodiment, the inner top surface of the display cabinet 2 and the top surface of the base 1 are both fixed with a limit frame 109 , and the display board 3 and the inner sliding arrangement of the limit frame 109 can limit the display board 3 through the limit frame 109 .

[0028] Working principle: When in use, first pull the display board 3 so that one end of the display board 3 is separated from the inside of the display cabinet 2. At this time, the first link 304 loses the restriction of the display cabinet 2, and the spring of the limit rod 308 rebounds and pushes the second link 306. Since the first link 304 is rotatably connected to the hidden groove 303, the second link 306 is rotatably connected to the first link 304, and the rebound sleeve rod 307 is rotatably connected to the hidden groove 303, when the second link 306 is pushed by the spring elastic force, it drives the first link 304 to rotate until the first link 304 is perpendicular to the display board 3, thereby supporting the bottom surface of the display board 3, and then place the news poster on the display board 3, and move the position of the magnetic strip 302 so that the plastic plate 302 presses the poster, and then the display board 3 can be reset, and the first link 304 is pushed by the display cabinet 2 The directional wheel 305 is squeezed by the extrusion, so that the directional wheel 305 shrinks into the hidden groove 303. When the transparent film 104 is contaminated and the news poster on the display cabinet 2 is unclear, the drive motor is started to drive the gear of the winding roller 103 to rotate. Under the meshing transmission of the two gears through the rack, the two winding rollers 103 rotate synchronously, so that the part of the transparent film 104 located at the display hole 102 starts to move, so that the clean part of the transparent film 104 moves to the display hole 102, and at the same time, the contaminated part of the transparent film 104 moves on the cleaning brush 202 and the cleaning sponge 203, so that the cleaning brush 202 and the cleaning sponge 203 clean the transparent film 104. The dust during cleaning enters the interior of the collection box 107 through the falling hole 108, and the cleaning brush 202 and the cleaning sponge 203 can be cleaned later by opening the switch cover 101.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
