[0025] Example

[0026] Reference Figure 1-Figure 2 , which is an embodiment of the utility model, provides a tourism promotion display stand, including: a display unit 100, a cover plate wiping unit 200 and a sponge scraping unit 300.

[0027] The display unit 100 includes a support plate 101 and two support rods 102 fixedly installed at both ends of the upper side wall of the support plate 101, a display plate 104 is fixedly arranged between the two support rods 102, both sides of the display plate 104 are fixedly connected to the support column 208 through a plurality of connecting rods 103, and the surface of the connecting rods 103 is plated with an anti-corrosion coating, the arrangement of the connecting rods 103 improves the connection stability between the display plate 104 and the support column 102, the arrangement of the anti-corrosion coating improves the anti-corrosion ability of the connecting rods 103, a matching glass cover 105 is hinged on the front of the display plate 104, a rain cover 106 is fixedly connected to the top of the plurality of support columns 208, and the rain cover 106 is arranged to be bent, the arrangement of the rain cover 106 can prevent the glass cover 105 from being broken by rain, snow, hail, etc., and protect the glass cover 105 and the display plate 104;

[0028] Further, the cover plate wiping unit 200 includes two first fixing ears 201 fixedly mounted on the upper side wall of the display plate 104, and a support column 208 corresponding to the first fixing ear 201 is fixedly mounted on the support plate 101, and each first fixing ear 201 is rotatably connected to the support column 208 through a threaded rod 202, and the horizontal height of the lower end of the threaded rod 202 is lower than the horizontal height of the lower end of the display plate 104, and the top of the threaded rod 202 upwardly penetrates the first fixing ear 201 and is fixedly sleeved with a transmission wheel, and the two transmission wheels are connected by a transmission belt 203 for transmission, and a first motor 204 is fixedly mounted on the top of the display plate 104, and the output shaft of the first motor 204 is fixedly connected to the top of one of the threaded rods 202, and a lifting nut 205 is threadedly connected to the threaded rod 202, and the two lifting nuts 205 are fixedly connected to a liquid storage box 206 together, and a wiping sponge 207 is fixedly provided on a side of the liquid storage box 206 close to the glass cover 105, and a plurality of groups of liquid seepage holes corresponding to the wiping sponge 207 are provided on the side wall of the liquid storage box 206;

[0029] Furthermore, the sponge scraping unit 300 is used to clean the wiping sponge 207;

[0030] The sponge scraping unit 300 includes two second fixing ears 301 fixedly mounted at both ends of the lower side wall of the display board 104 and a second motor 302 fixedly mounted on one of the second fixing ears 301. In the present invention, the first motor 204 and the second motor 302 are both forward and reverse servo motors, and their motor output shafts can be both forward and reverse. The output shaft of the second motor 302 passes through the second fixing ear 301 and is fixedly connected with a screw rod 303. The screw rod 303 is threadedly connected with a moving nut 304 that is laterally slidably connected to the display board 104. A guide rod 305 is also fixedly connected between the two second fixing ears 301. A guide sleeve 306 is slidably sleeved on the guide rod 305. The guide sleeve 306 is fixedly connected to the moving nut 304. The moving nut 304 can be adjusted by the coordinated use of the guide rod 305 and the guide sleeve 306. 304 moves on the screw rod 303 for guiding and limiting. A side of the moving nut 304 close to the front end of the display board 104 is fixedly connected to a scraper 308 through a connecting column 307, and the scraper 308 matches the position of the wiping sponge 207. A first elastic switch 309 is fixedly installed on one of the support columns 208, and the second motor 302 and the first motor 204 are both electrically connected to the first elastic switch 309. A second elastic switch 310 is fixedly installed on one of the second fixing ears 301, and the first motor 204 and the second motor 302 are both electrically connected to the second elastic switch 310. An extrusion block 311 corresponding to the second elastic switch 310 is fixedly installed on the moving nut 304. Through the setting of the extrusion block 311, it is ensured that the second elastic switch 310 can be stably squeezed during the movement of the moving nut 304.

[0031] During use, when a large amount of dust accumulates on the surface of the glass cover 105, affecting the normal display effect of the display stand, the first motor 204 is started, and the first motor 204 drives the two threaded rods 202 to rotate forwardly through the transmission wheel 203 and the transmission belt at the same time, and the lifting nut 205 threadedly connected to the threaded rod 202 drives the liquid storage box 206 and the wiping sponge 207 to move downward, and the water-permeated wiping sponge 207 can effectively wipe off the dust attached to the glass cover 105, without manual wiping, ensuring that the display stand always maintains a good display effect;

[0032] When the lifting nut 205 drives the liquid storage box 206 and the wiping sponge 207 to move to the lowest end, the wiping sponge 207 is completely staggered with the display board 104, and the lifting nut 205 squeezes the first elastic switch 309, the first elastic switch 309 turns off the first motor 204, and controls the output shaft of the second motor 302 to drive the screw rod 303 to rotate forward, and the moving nut 304 threadedly connected with the screw rod 303 drives the scraper 308 to move horizontally through the connecting column 307, and the scraper 308 can remove the dust adsorbed on the surface of the wiping sponge 207. The dust particles are scraped off. When the movable nut 304 moves to the end, the dust on the wiping sponge 207 is completely scraped off. The movable nut 304 squeezes the second elastic switch 310, and the second elastic switch 310 controls the first motor 204 and the second motor 302 to reverse, so that the liquid storage box 206 and the scraper 308 are reset to the initial state, which is convenient for cleaning the glass cover 105 next time. At the same time, the defect that the dust attached to the wiping sponge 207 causes poor wiping effect on the glass cover 105 and easy scratching of the glass cover 105 is solved.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
