[0024] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.

[0025] In order to solve the problems existing in the background technology, this application proposes the following technical solution: an outdoor advertising screen.

[0026] The specific technical solution includes an advertising screen body 1, a base 2 at the bottom of the advertising screen body 1, and a lifting and fixing assembly 3 inside the base 2. The lifting and fixing assembly 3 includes a lifting plate 301, a guide groove 303, a sliding plate 306, a sliding groove 307, a fixing seat 311, and a mounting seat 315. The lifting plate 301 and the sliding plate 306 are slidably connected inside the base 2. A moving wheel 302 is fixed on the outer wall of the bottom of the lifting plate 301. Guide blocks 304 are fixed on the outer walls on both sides of the lifting plate 301. The guide groove 303 is opened on the inner wall of the base 2, and the guide blocks 304 are slidably connected to the guide groove. Inside 303, a spring 305 connected to a guide block 304 is provided on the inner wall of the guide groove 303. A slide groove 307 is opened on the inner wall of the base 2, and both ends of the slide plate 306 are slidably connected to the inside of the slide groove 307. A dual-axis motor 308 is fixedly installed on the inner wall of the top of the base 2, and a lead screw 309 is provided on the output shaft of the dual-axis motor 308. The slide plate 306 is threadedly sleeved on the outside of the lead screw 309. A pressing block 310 is fixedly installed on the outer wall of the bottom of the slide plate 306, which can drive the moving wheel 302 to descend until the base 2 is lifted slightly above the ground, making it easy to move the outdoor advertising screen.

[0027] The fixing base 311 is fixedly installed on the inner wall of the base 2, and the fixing base 311 is slidably connected to the inside of the fixing base 311. The insert block 312 is inserted into the inside of the mounting base 315. The inner wall of the fixing base 311 is provided with a spring 313 connected to the insert block 312. A push block 314 extending to the outside of the fixing base 311 is fixedly installed on the outer wall of one side of the insert block 312, which can quickly fix the outdoor advertising screen.

[0028] In specific implementations, such as Figure 1 and Figure 4 As shown, a cleaning component 4 is provided on the top of the advertising screen body 1. The cleaning component 4 includes a cleaning seat 401, a sliding seat 402 and a rotating rod 406. The cleaning seat 401 is fixedly installed on the outer wall of the top of the advertising screen body 1. The cleaning component 4 is used to automatically clean the dust on the advertising screen body 1, which is very convenient to use.

[0029] Furthermore, the slide 402 is slidably connected inside the cleaning seat 401. A limit rod 405 is fixedly provided on the inner wall of the cleaning seat 401. The slide 402 is slidably sleeved on the outside of the limit rod 405. The limit rod 405 can guide and limit the slide 402.

[0030] Furthermore, a single-axis motor 403 is fixedly installed on the outer wall of one side of the cleaning seat 401, and a screw 404 is installed on the output shaft of the single-axis motor 403. The slide 402 is threaded onto the outside of the screw 404. The single-axis motor 403 can drive the screw 404 to rotate, so that the slide 402 moves axially on the screw 404.

[0031] Furthermore, the top of the rotating rod 406 is rotatably connected to the outer wall of the bottom of the slide 402, and a cleaning brush 409 is provided on the outer wall of the rotating rod 406. The cleaning brush 409 contacts the advertising screen body 1 and can clean the dust on the advertising screen body 1.

[0032] Furthermore, a gear ring 407 is fixedly installed on the outer wall of the top of the rotating rod 406, and a gear plate 408 is fixedly installed on the outer walls of both sides of the cleaning seat 401. The gear plate 408 and the gear ring 407 mesh with each other, enabling the gear ring 407 to drive the rotating rod 406 to rotate.

[0033] Furthermore, a waterproof cover 410 is fixedly installed on the outer wall of one side of the cleaning seat 401, and the waterproof cover 410 is located outside the single-axis motor 403. The bottom of the waterproof cover 410 is empty, which can achieve the waterproof function without affecting the heat dissipation of the single-axis motor 403.

[0034] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0035] When the outdoor advertising screen needs to be moved during use, the dual-axis motor 308 is turned on to drive the lead screw 309 to rotate, which allows the sliding plate 306 to move axially on the lead screw 309. The sliding plate 306 will drive the pressing block 310 away from the push block 314. The spring 313 pushes the insert block 312 to move out of the mounting base 315, continuing to drive the sliding plate 306 to move. The sliding plate 306 drives the pressing block 310 to move and press against the inclined surface of the lifting plate 301, which allows the lifting plate 301 to drive the moving wheel 302 to move down until the base 2 is slightly higher than the ground. The moving wheel 302 facilitates the movement of the advertising screen body 1 and makes the movement more effortless. When the outdoor advertising screen needs to be installed, the mounting base 315 is preset to be fixed at the installation location. Turning on the dual-axis motor 308 to drive the lead screw 309 to rotate allows the sliding plate 306 to drive the pressing block 310 to move without pressing against the lifting plate 301. The spring 305's elasticity... The spring can push the lifting plate 301 and the moving wheel 302 upward, and store the moving wheel 302 inside the base 2. As the sliding plate 306 drives the pressing block 310 to move, the pressing block 310 presses the pushing block 314, and the pushing block 314 drives the insert block 312 to move, so that the insert block 312 is inserted into the inside of the mounting base 315, which can fix the base 2 and the mounting base 315, making the installation of the advertising screen more stable and reliable. Turning on the single-axis motor 403 drives the screw 404 to rotate, which can make the sliding base 402 synchronously drive the rotating rod 406 and the cleaning brush 409 to move. When the rotating rod 406 moves, the toothed ring 407 above it will mesh with the toothed plate 408, which can make the rotating rod 406 and the cleaning brush 409 rotate at the same time as moving, which can clean the dust on the advertising screen body 1, prevent the dust from affecting the clarity of the advertising screen body 1 when playing advertisements, and eliminate the need for manual cleaning, making it more convenient to use.
