[0030] Please see Figure 1-9This utility model provides a technical solution: an outdoor adjustable LED display screen fixing device, including a base plate 1, with movable wheels 5 installed at the four corners of the bottom side of the base plate 1, a support plate 9 fixedly connected to the middle of the top side of the base plate 1, a fixing pipe 2 fixedly installed on the top side of the support plate 9, a lifting plate 6 provided on the top side of the fixing pipe 2, a mounting bracket 7 fixedly installed on the top side of the lifting plate 6, a mounting plate 8 fixedly installed on the front side of the mounting bracket 7, an LED display screen 3 provided on the front side of the mounting plate 8, a fixing component installed on the base plate 1, a lifting component for lifting the lifting plate 6 installed on the fixing pipe 2, and a quick-release component installed between the mounting plate 8 and the LED display screen 3.

[0031] When using this outdoor adjustable LED display screen fixing device, the device is moved by four sets of moving wheels 5. After being moved to the required area, it is fixed with anti-slip components. Then, the LED display screen 3 is quickly installed on the mounting plate 8 through quick-release components. Subsequently, the lifting plate 6 is raised and lowered by the lifting components, thereby driving the mounting bracket 7 and the mounting plate 8 to rise and fall, ultimately realizing the height adjustment of the LED display screen 3.

[0032] The fixing assembly includes a circular plate 15, a support plate 9 with a placement groove 16 inside, the circular plate 15 is rotatably mounted on the placement groove 16, the base plate 1 has mounting grooves 10 through all four sides, and fixing plates 11 are rotatably mounted on the four mounting grooves 10. Four sliding plates 18 are slidably passed through the side wall of the support plate 9. The top of each of the four fixing plates 11 is hinged to a connecting plate 12, and the other end of each of the four connecting plates 12 is hinged to the four sliding plates 18. Four arc-shaped sliding grooves 17 are through the circular plate 15. Two clamping plates 19 are fixedly connected to the side of the sliding plate 18 near the circular plate 15. The two clamping plates 19 abut against the upper and lower sides of the circular plate 15, and a sliding rod 20 is fixedly connected between the two clamping plates 19. The sliding rod 20 is slidably connected to the arc-shaped sliding groove 17. A positioning mechanism is also installed on the support plate 9.

[0033] The positioning mechanism includes a toothed plate 14, which is fixedly connected to the top side of the base plate 1. The side wall of the support plate 9 is also provided with a sliding groove 13. The side wall of the circular plate 15 is fixedly connected with a sliding rod 37, which is slidably connected to the sliding groove 13. The other end of the sliding rod 37 is fixedly connected with a fixing block 38. The inside of the fixing block 38 is provided with a placement groove 39. An insert rod 40 is slidably inserted through the fixing block 38. A limiting plate 42 is fixedly sleeved on the insert rod 40. A spring 41 is also sleeved on the insert rod 40.

A toothed block 43 is fixedly connected to the bottom end of the insert rod 40, and the toothed block 43 meshes with the toothed plate 14.

[0034] When using the fixing component, the user pulls up the insertion rod 40, causing the toothed block 43 to disengage from the toothed plate 14 and release its engagement lock. Then, the user pushes the fixing block 38, causing the sliding rod 37 to slide on the sliding groove 13, thereby rotating the circular plate 15. This causes the sliding rod 20, which is directly fixedly connected to the two sets of clamping plates 19, to slide on the arc-shaped sliding groove 17, thereby pushing the sliding plate 18 to slide out on the support plate 9. This, in turn, pushes the fixing plate 11 to rotate in the mounting groove 10 through the connecting plate 12, so that the bottom side of the fixing plate 11 contacts or inserts into the ground, thus fixing the device on the outdoor ground. After fixing, the insertion rod 40 is released, and the insertion rod 40 slides downward under the action of the spring 41, thereby causing the toothed block 43 and the toothed plate 14 to re-engage and lock.

[0035] The lifting assembly includes a screw 29, which is rotatably installed inside the fixed tube 2. A sliding plate 35 is threaded onto the screw 29. Connecting plates 36 are fixedly connected to all four sides of the sliding plate 35. Slide grooves 30 are opened through all four sides of the fixed tube 2. The connecting plates 36 are slidably connected to the slide grooves 30. The tops of the four sets of connecting plates 36 are fixedly connected to the bottom side of the lifting plate 6. A rotating mechanism for rotating the screw 29 is also installed on the fixed tube 2.

[0036] The rotating mechanism includes a rotating rod 33, which is rotatably inserted through the bottom right side of the fixed tube 2. A bevel gear 32 is fixedly sleeved on the bottom outer surface of the screw 29. A bevel gear 31 is fixedly connected to one end of the rotating rod 33 near the screw 29. The bevel gear 31 meshes with the bevel gear 32. A rotating handle 34 is fixedly connected to the other end of the rotating rod 33.

[0037] When the lifting assembly is in use, the rotating handle 34 is turned manually, which in turn rotates the rotating rod 33, causing the first bevel gear 31 to rotate, which in turn drives the second bevel gear 32 that meshes with it, thereby rotating the screw 29. This causes the second sliding plate 35, which is threaded onto the screw 29, to slide and rise, thereby driving the four sets of connecting plates 36 to slide and rise on the sliding groove 30, and thus driving the lifting plate 6 to rise and fall.

[0038] The quick-release assembly includes a plug 21 and a fixing block 23. The plug 21 is fixedly installed on the rear side of the LED display screen 3, and the fixing block 23 is fixedly installed on the front side of the mounting plate 8. A slot 25 is provided on the left side of the fixing block 23, and the plug 21 is inserted into the slot 25. A limiting rod 24 is slidably passed between the left and right sides of the fixing block 23. A limiting groove 22 is provided through the bottom of the plug 21, and the left end of the limiting rod 24 passes through the limiting groove 22. A limiting mechanism is provided on the right side of the fixing block 23.

[0039] The limiting mechanism includes a spring 28, a placement groove 27 is provided inside the right side of the fixing block 23, a limiting plate 26 is fixedly sleeved on the limiting rod 24, the left side of the limiting plate 26 abuts against the left side of the placement groove 27, the spring 28 is sleeved on the limiting rod 24, and the left and right sides of the spring 28 abut against the right side of the limiting plate 26 and the right side of the placement groove 27, respectively.

[0040] When using the quick-release assembly, the user pulls the limiting rod 24, causing the left end of the limiting rod 24 to retract into the second placement slot 27. Then, the insertion block 21 on the rear side of the LED display screen 3 is inserted into the slot 25 opened in the first fixing block 23. Then, the limiting rod 24 is released. Under the action of the spring 28 pushing the limiting plate 26, the limiting rod 24 is pushed into the limiting slot 22 that is opened through the bottom of the insertion block 21, thus realizing the quick installation of the LED display screen 3.

[0041] The top of the LED display screen 3 is fixedly connected to a lifting handle 4, making it easy to carry the LED display screen 3.

[0042] The bottom of the fixed plate 11 is fixedly connected with several anti-slip teeth, which increase the friction when in contact with a hard ground.

[0043] The fixing plate 11 is made of stainless steel to prevent rusting when inserted into soft ground.

[0044] Working principle: When using this outdoor adjustable LED display fixing device, the device is moved by four sets of moving wheels 5. After moving to the required area, the user pulls up the plug rod 40, which causes the toothed block 43 to disengage from the toothed plate 14 and release its engagement lock. Then, the fixing block 38 is pushed, which causes the sliding rod 37 to slide on the sliding groove 13, thereby rotating the circular plate 15. This causes the sliding rod 20, which is directly fixed to the two sets of clamping plates 19, to slide on the arc-shaped sliding groove 17, thereby pushing the sliding plate 18 to slide out on the support plate 9. This, in turn, pushes the fixing plate 11 to rotate in the mounting groove 10 through the connecting plate 12, so that the bottom side of the fixing plate 11 contacts or inserts into the ground, thus fixing the device to the outdoor ground. After fixing, the plug rod 40 is released, and the plug rod 40 slides downward under the action of the spring 41, thereby causing the toothed block 43 and the toothed plate 14 to re-engage and lock. Then, the user... The limit rod 24 is pulled by a person, causing the left end of the limit rod 24 to retract into the second slot 27. Then, the insert block 21 on the back of the LED display screen 3 is inserted into the slot 25 opened in the first fixing block 23. Then, the limit rod 24 is released. Under the action of the spring 28 pushing the limit plate 26, the limit rod 24 is pushed into the limit slot 22 opened through the bottom of the insert block 21, realizing the quick installation of the LED display screen 3. Then, by manually turning the rotating handle 34, the rotating rod 33 is turned, which drives the first bevel gear 31 to rotate, which in turn drives the second bevel gear 32 that meshes with it, thereby turning the screw 29. This causes the second sliding plate 35, which is threaded on the screw 29, to slide and rise, which drives the four sets of connecting plates 36 to slide and rise on the second sliding groove 30, which in turn drives the lifting plate 6 to rise and fall, which in turn drives the mounting bracket 7 and the mounting plate 8 to rise and fall, finally realizing the height adjustment of the LED display screen 3.
