[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figures 1 to 8 As shown, a display screen hanging support device according to an embodiment of the present invention comprises a hanging seat 1, a support tube 2 is fixed to the bottom end of the hanging seat 1, a mounting frame 4 is arranged on one side of the support tube 2, a display screen body 5 is installed on the side of the mounting frame 4 away from the support tube 2, a screw rod 22 is rotatably connected inside the support tube 2, a sleeve 23 is slidably connected inside the support tube 2, the screw rod 22 and the sleeve 23 are threadedly connected, a first motor 21 is installed on the top end of the support tube 2 away from the mounting frame 4, a pulley is fixed to the end of the rotating shaft of the first motor 21, and the screw rod 22 is connected to the sliding sleeve 23. 2 is also fixed with a pulley at the top, the screw rod 22 and the pulley of the first motor 21 are connected by a belt, the sleeve 23 is movably connected with the mounting frame 4, a connector 231 is fixed at the end of the sleeve 23, a docking block 41 is fixed at the end of the mounting frame 4, a rotating head 411 is fixed on the side of the docking block 4 away from the mounting frame 4, the rotating head 411 is rotatably connected with the connector 231, a plurality of second teeth 413 are fixed at equal intervals below the rotating head 411, and a plurality of first teeth 24 are fixed at equal intervals on the side of the support tube 2 close to the mounting frame 4;

[0034] When using the display screen body 5 in some public places, it is necessary to install it at a higher position to prevent the display screen body 5 from affecting pedestrians and preventing pedestrians and objects from damaging the display screen body 5. When in use, the hanging seat 1 is installed on the ceiling at the location where it needs to be used, and then the mounting frame 4 is connected to the display screen body 5. During use, the display screen body 5 is supported by the support tube 2 and the mounting frame 4. At this time, the display screen body 5 can be suspended in mid-air for display, and pedestrians are not easy to touch the display screen body 5, so it will not cause damage to the display screen body 5. Different scenes use different heights, so it is necessary to adjust the height of the display screen body 5 according to the usage scene, start the first motor 21 to drive the screw 22 to rotate, the screw 22 drives the sliding sleeve 23 to slide inside the support tube 2, and the sliding sleeve 23 slides through the installation The mounting frame 4 drives the display screen body 5 to be raised and lowered, and can be adjusted to a corresponding height as needed. When the display screen body 5 is installed at a higher position, the display screen body 5 will be inconvenient to watch, so the display screen body 5 needs to be adjusted to a certain angle. At this time, the sliding sleeve 23 drives the mounting frame 4 to move to the bottom of the support tube 2. During this process, the second tooth 413 is driven by the first tooth 24, and the second tooth 413 drives the rotating head 411 to rotate 30°. The rotating head 411 drives the mounting frame 4 to rotate 30° through the docking block 41, so that the mounting frame 4 can drive the display screen body 5 to rotate 30°. At this time, the angle of the display screen body 5 is more convenient for pedestrians to watch. When it needs to be folded up, the sliding sleeve 23 rises. At this time, under the action of the first tooth 24 and the second tooth 413, the rotating head 411 can be rotated 30° in the opposite direction, so that the display screen body 5 can be restored to its initial state.

[0035] like Figures 1 to 8 As shown, a shielding plate 3 is fixed to one side of the hanging seat 1 close to the display screen body 5, and a brush roller 34 is rotatably connected to the bottom end of the shielding plate 3. A liquid guide brush 332 is arranged above the brush roller 34, and a dustproof film 314 is arranged above the liquid guide brush 332;

[0036] After long-term use, dust will accumulate on the surface of the display screen body 5, and the display effect of the display screen body 5 will be affected. Therefore, it needs to be cleaned. However, because the display screen body 5 is suspended in the air, it is not convenient to clean. Therefore, the first motor 21 is started to drive the screw 22 to rotate, and the screw 22 drives the sliding sleeve 23 to slide inside the support tube 2. When the sliding sleeve 23 slides, it drives the display screen body 5 to rise upward through the mounting frame 4. During the rising process of the display screen body 5, it will first contact the brush roller 34. At this time, the brush roller 34 first preliminarily brushes the surface of the display screen body 5 to remove the dust on the surface, but it may When external liquid or the like splashes onto the surface of the display screen main body 5, residues will be left after the water evaporates and are difficult to clean. At this time, cleaning liquid is applied to the display screen main body 5 through the liquid guide brush 332, and the residues are dissolved by the cleaning liquid, so that the surface of the display screen main body 5 can be cleaned. Subsequently, the surface of the display screen main body 5 is covered with the dustproof film 314 to shield the surface of the display screen main body 5 from dust accumulation when not in use. When it is needed, the first motor 21 rotates in the reverse direction to lower the display screen main body 5 to the height when in use, so that the surface of the display screen main body 5 can be easily cleaned and protected when not in use.

[0037] like Figures 1 to 8 As shown, both sides of the brush roller 34 are rotatably connected to a support frame 341, a second motor 342 is installed on one side of the support frame 341, a gear is fixed to the end of the rotating shaft of the second motor 342, and a toothed disc is fixed to both ends of the rotating shaft of the brush roller 34, and the gear is meshed with the toothed disc;

[0038] When the brush roller 34 cleans the surface of the display screen body 5, the second motor 342 rotates through the gear at the end to drive the toothed disc, and the toothed disc drives the brush roller 34 to rotate. At this time, the brush roller 34 rotates to brush off the dust on the surface of the display screen body 5. During the cleaning process, dust accumulates on the surface of the brush roller 34, causing the cleaning effect to deteriorate.

[0039] like Figures 1 to 8 As shown, guide frames 335 are fixed on both sides of the bottom end of the shielding plate 3, a liquid guide shell 33 is fixed between the guide frames 335, a liquid guide brush 332 is arranged inside the liquid guide shell 33, an end of the liquid guide brush 332 close to the brush roller 34 extends from the inside of the liquid guide shell 33, and an end of the liquid guide shell 33 away from the brush roller 34 is connected to a liquid storage tank 331 through a pipeline;

[0040] The interior of the liquid storage tank 331 is filled with cleaning liquid, and the liquid storage tank 331 transmits the cleaning liquid to the interior of the liquid guiding shell 33 through a pipeline. The liquid guiding shell 33 conducts the cleaning liquid to the interior of the liquid guiding brush 332. When the liquid guiding brush 332 contacts the display screen body 5, the cleaning liquid can be brushed on the surface of the display screen body 5, which can facilitate the application of the cleaning liquid to the surface of the display screen body 5.

[0041] like Figures 1 to 8As shown, a cover plate 333 is provided above and below the liquid guide brush 332, and connecting arms 334 are fixed on both sides of the cover plate 333. Guide holes are opened above and below the guide frame 335, and the connecting arms 334 are slidably connected in the guide holes through a connecting shaft. The middle part of the guide frame 335 away from the liquid guide shell 33 is slidably connected with a pull rod 336 through a support block, and one end of the pull rod 336 away from the brush roller 34 is fixedly connected to the support frame 341, and a second spring 337 is sleeved on the outside of the pull rod 336, one end of the second spring 337 is fixedly connected to the pull rod 336, and the other end of the second spring 337 is rotatably connected to a connecting rod 338, and the other end of the connecting rod 338 is rotatably connected to the connecting arm 334;

[0042] Most of the internal components of the cleaning liquid are water. When not in use, the water will evaporate into the air through the liquid guiding brush 332, which will cause the cleaning liquid to be quickly consumed. Therefore, two cover plates 333 are set to cover the outside of the liquid guiding brush 332 when not in use. When it is needed, the display screen body 5 will first contact the brush roller 34. The initial position of the brush roller 34 is relatively forward. Therefore, when the display screen body 5 is raised, the brush roller 34 will be pushed to move backward first. At this time, the brush roller 34 pulls the pull rod 336 through the support frame 341, and the pull rod 336 pulls the two connecting rods 338 to move. The connecting rod 338 will drive the connecting arm 334 to move at this time. Under the guidance of the guide hole inside the guide frame 335, The connecting arm 334 drives the cover plate 333 to separate from each other for a distance first, and then pulls the cover plate 333 to move toward the rear end of the liquid guide shell 33, at which time the cover plate 333 can be separated from the liquid guide brush 332, and at this time the liquid guide brush 332 can apply cleaning liquid to the surface of the display screen body 5, and when the display screen body 5 passes through the brush roller 34, the brush roller 34 loses thrust, and at this time the elastic force of the second spring 337 can drive the cover plate 333 to automatically reset, and a sponge pad is provided at one end of the cover plate 333 close to the brush roller 34 to prevent the cover plate 333 from bumping against the display screen body 5 when resetting, so as to facilitate the application of cleaning liquid to the display screen body 5, and at the same time prevent the liquid guide brush 332 from evaporating the moisture of the cleaning liquid when not in use.

[0043] like Figures 1 to 7 As shown, a water-absorbing cotton 35 is arranged above the liquid-guiding shell 33, and both sides of the water-absorbing cotton 35 are fixedly connected to the guide frame 335;

[0044] After the liquid guiding brush 332 applies cleaning liquid to the surface of the display screen main body 5, the absorbent cotton 35 will come into contact with the display screen main body 5. At this time, the absorbent cotton 35 can wipe off the residual cleaning liquid and decomposed objects on the surface of the display screen main body 5, thereby preventing the cleaning liquid from remaining on the surface of the display screen main body 5. When the display screen main body 5 descends, the liquid guiding brush 332 will also apply cleaning liquid to its surface, and at this time, the brush roller 34 can wipe off the residual cleaning liquid.

[0045] like Figures 1 to 6As shown, a winding roller 313 is provided below the shielding plate 3, and both ends of the winding roller 313 are rotatably connected to connecting blocks, and the top of the connecting block is fixedly connected to the shielding plate 3, and a coil spring 315 is fixed to the outside of the rotating shaft of the winding roller 313, and the outer side of the coil spring 315 is fixedly connected to the connecting block, and a dustproof film 314 is wound on the outside of the winding roller 313, and slide grooves 31 are provided on both sides of the shielding plate 3, and a top plate 311 is provided at the bottom end of the shielding plate 3, and second sliders 312 are fixed on both sides of the top plate 311, and the second slider 312 is slidably connected to the inside of the slide groove 31, and the other end of the dustproof film 314 is fixedly connected to the top plate 311;

[0046] When the display screen body 5 is wiped by the absorbent cotton 35, the cleaning work is completed. At this time, the top of the display screen body 5 contacts the top plate 311, and the display screen body 5 pushes the top plate 311 to pull the dustproof film 314 to unwind from the inside of the winding roller 313. At this time, the dustproof film 314 will stick to the surface of the display screen body 5 during the process. When the display screen body 5 rises to the highest point, the dustproof film 314 can completely cover the surface of the display screen body 5, which can prevent dust from accumulating on the surface of the display screen body 5 when not in use. During this process, the second slider 312 slides inside the slide groove 31 to guide the top plate 311, and the winding roller 313 drives the winding spring 315 to tighten. When the display screen body 5 descends, the tension of the winding spring 315 will drive the winding roller 313 to rotate in the opposite direction to rewind the dustproof film 314, and at the same time pull the top plate 311 back to the initial position, which can automatically block the surface of the display screen body 5 and automatically reset after use.

[0047] like Figures 1 to 10 As shown, one end of the shielding plate 3 away from the top plate 311 is rotatably connected to a flip frame 32, a push bar 321 is fixed to the bottom end of the flip frame 32, and a push plate 322 is fixed to the top end of the flip frame 32;

[0048] When the top plate 311 reaches the top of the slide groove 31, the top plate 311 will push the push plate 322 through the inclined surface of the push plate 322. At this time, the push plate 322 pushes the flip frame 32 to flip, and the flip frame 32 drives the push bar 321 at its bottom to push the dustproof film 314 forward. At this time, under the push of the push bar 321, the dustproof film 314 can be pressed against the surface of the display screen body 5, so that the dustproof film 314 can be closer to the display screen body 5 to prevent dust from entering the gap between the dustproof film 314 and the display screen body 5.

[0049] like Figures 1 to 4 As shown, the connecting head 231 is movably connected with a lifting column 235 inside, a clamping frame 236 is fixed to the top of the lifting column 235, a clamping slot 412 is provided at the top of the rotating head 411, and the clamping frame 236 can be engaged with the clamping slot 412, and a top column 25 is provided below the first tooth 24, and the top column 25 is fixedly connected to the support tube 2;

[0050] After use, the display screen body 5 needs to be raised, but the rotating head 411 and the connecting head 231 are rotatably connected. In order to prevent rotation during the raising process, the bracket 236 is stuck in the inside of the slot 412 during the raising process. At this time, the lifting column 235 is inserted into the inside of the connecting head 231, and the rotating head 411 and the connecting head 231 can be fixed. When the display screen body 5 is raised, it will be in a stable state. When the display screen body 5 needs to rotate an angle, the lifting column 235 drives the bracket 236 to rise and separate the bracket 236 from the slot 412. At this time, the rotating head 411 can rotate outside the connecting head 231, so that the display screen body 5 can be in a stable state during the raising process of the sliding sleeve 23.

[0051] like Figures 1 to 4 As shown, a sliding cavity 232 is provided inside the connecting head 231, a first slider 234 is fixed to one side of the lifting column 235, the first slider 234 is slidably connected inside the sliding cavity 232, a first spring 233 is fixed to the top of the first slider 234, and the top of the first spring 233 is fixedly connected to the inner wall of the sliding cavity 232;

[0052] When the sliding sleeve 23 descends, the top column 25 will be inserted into the interior of the connecting head 231. At this time, the top column 25 will lift the lifting column 235, so that the bracket 236 can be separated from the slot 412. At the same time, the second teeth 413 are engaged with the first teeth 24, so that the bracket 236 can be automatically separated from the slot 412. At the same time, when the sliding sleeve 23 rises, the top column 25 and the lifting column 235 are gradually separated. At this time, the first spring 233 inside the sliding cavity 232 pushes the first slider 234 to drive the lifting column 235 to reset. The lifting column 235 can drive the bracket 236 to gradually reset. When the first teeth 24 are separated from the second teeth 413, the bracket 236 is inserted into the interior of the slot 412, so that the rotating head 411 and the connecting head 231 can be automatically fixed.
