Technical Field

[0001] This utility model relates to the field of LED display technology, specifically to an adjustment mechanism for an LED display. Background Technology

[0002] With the continuous development of LED display technology, LED displays are being used more and more widely in various fields. However, traditional LED displays are often difficult to adjust after installation, and the fixing methods are relatively simple, which cannot meet the needs of different scenarios. Therefore, there is a need for an adjustment mechanism that can easily adjust the angle of the LED display and maintain its stability.

[0003] Referring to the LED display adjustment mechanism disclosed in CN211083405U, the mechanism includes a base, a support leg fixedly connected to the top of the base, and a fixed rod movably connected to the top of the support leg. This adjustment mechanism, through the coordinated use of the base, support leg, fixed rod, LED display body, support column, chuck, fixing mechanism, handle rod, spring, first limiting plate, slot, first wheel, first connecting column, transmission mechanism, rotating shaft, first bevel gear, second bevel gear, swing mechanism, second wheel, second connecting column, sleeve, second limiting plate, and connecting rod, solves the problem that existing LED displays cannot be adjusted in position, making them inconvenient for users and reducing their practicality. This LED display adjustment mechanism has the advantage of being able to adjust the position of the LED display, facilitating user operation and improving the practicality of the LED display. However, as can be seen from the above, while this adjustment mechanism can be well applied, it is generally not convenient for horizontally adjusting the angle of the LED display body, thus making it difficult to display text and graphic information from all angles, and further improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustment mechanism for an LED display screen, so as to solve the problem that although the adjustment mechanism mentioned in the background art can be well applied, it is usually not convenient to horizontally adjust the angle of the LED display screen body, thus making it difficult to display graphic and text information from all angles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustment mechanism for an LED display screen, comprising a base, a circular base plate at the center of the top of the base, an I-shaped plate mounted on the top of the circular base plate via a bracket, a positioning seat on one side of the top of the I-shaped plate, a second motor mounted on the inner wall of the positioning seat via a bracket, a drive wheel mounted on the top of the second motor, a first rotating shaft rotatably mounted at the center of the top of the I-shaped plate, a driven wheel at the top of the first rotating shaft, a transmission belt wound around the outer wall between the driven wheel and the drive wheel, a transmission frame mounted on the top of the driven wheel via a guide shaft, a U-shaped frame on one side of the top of the transmission frame, second rotating shafts rotatably mounted on the inner walls of both sides of the U-shaped frame, and an LED display screen body mounted above the transmission frame between the second rotating shafts.

[0006] Preferably, the transmission frame is equipped with a lead screw inside, one end of which is rotatably connected to the inner wall of one side of the transmission frame. The lead screw is provided to facilitate the placement of the nut assembly.

[0007] Preferably, a nut pair is threaded onto the outer wall of the lead screw, and a drive arm is rotatably mounted on the top of the nut pair. The end of the drive arm away from the nut pair is rotatably connected to the bottom end of the LED display body. The nut pair and the drive arm are configured to tilt and adjust the angle of the LED display body.

[0008] Preferably, a first motor is installed on the outer wall of one side of the transmission frame. One end of the first motor extends into the interior of the transmission frame and is connected to one end of the lead screw. The first motor is configured to drive the lead screw to rotate.

[0009] Preferably, each corner of the base is provided with a placement cavity, and a strip seat is rotatably installed inside the placement cavity. One end of the strip seat extends to the outside of the placement cavity. The strip seat is provided to accommodate the positioning hole.

[0010] Preferably, the upper and lower surfaces of the strip seat away from the base are provided with positioning holes, one end of which extends into the interior of the strip seat. The positioning holes are provided to allow the base to be bolted and installed.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the adjustment mechanism of the LED display screen not only improves the display range of graphic information of the LED display screen body when the adjustment mechanism is used, but also improves the convenience of using the adjustment mechanism, and achieves the purpose of easy positioning and placement of the adjustment mechanism.

[0012] (1) The second motor drives the active wheel to rotate, so that the active wheel drives the driven wheel to rotate synchronously via the transmission belt, so that the driven wheel drives the LED display body to rotate via the transmission frame, thereby horizontally adjusting the angle of the LED display body, so that the LED display body can display graphic and text information from all directions, thereby improving the display range of graphic and text information of the LED display body when the adjustment mechanism is used.

[0013] (2) The first motor drives the lead screw to rotate, so that the nut pair slides on the outer wall of the lead screw, so that the nut pair drives the LED display body to move accordingly via the drive arm. At this time, one end of the LED display body rotates on the inner wall of the U-shaped frame via the second rotating shaft, so that the tilt angle of the LED display body can be automatically adjusted according to the usage requirements, thereby improving the convenience of using the adjustment mechanism.

[0014] (3) By placing the base on the display platform, then rotating the strip seat to move one end of the strip seat away from the outside of the placement cavity, and then using the bolt to pass through the positioning hole and screw into the threaded hole reserved in the display platform, the base can be bolted and placed on the display platform, thereby achieving the purpose of easily positioning and placing the adjustment mechanism.

A positioning seat 10 is provided on one side of the top of the I-shaped plate 9. A second motor 11 is mounted on the inner wall of the positioning seat 10 via a bracket. A drive wheel 15 is mounted on the top of the second motor 11. A first rotating shaft 18 is rotatably mounted at the center of the top of the I-shaped plate 9. A driven wheel 17 is provided on the top of the first rotating shaft 18. A transmission belt 16 is wound on the outer wall between the driven wheel 17 and the drive wheel 15. A transmission frame 6 is mounted on the top of the driven wheel 17 via a guide shaft. A lead screw 12 is provided inside the transmission frame 6. One end of the lead screw 12 is rotatably connected to the inner wall of one side of the transmission frame 6.

[0026] In use, the lead screw 12 is used to accommodate the nut assembly 13.

[0027] A nut pair 13 is threaded on the outer wall of the lead screw 12. A drive arm 14 is rotatably mounted on the top of the nut pair 13. The end of the drive arm 14 away from the nut pair 13 is rotatably connected to the bottom of the LED display screen body 8.

[0028] In use, the angle of the LED display body 8 can be adjusted by setting the nut pair 13 and the drive arm 14.
