Description

Technical Field

[0001] The utility model relates to the technical field of LED display screen lifting, in particular to a LED display screen lifting structure. Background Art

[0002] As we all know, LED electronic displays are a display method that controls semiconductor light-emitting diodes. They are composed of tens to hundreds of thousands of evenly arranged semiconductor light-emitting diode pixels. Different materials can be used to create LED pixels of different colors to display text, graphics, images, animations, market information, videos, and recordings. Some small LED displays require installation on a lifting structure for use.

[0003] In real life, LED display screens are widely used. For example, they can be used in company meetings, shopping mall performances, or families who like to watch movies. In order to facilitate the height adjustment of the LED display screen, an LED display screen lifting structure is required. However, after the height of the LED display screen is raised, the center of gravity of the LED display screen will rise with the common LED display screen lifting structure, and the device cannot adjust the position of the center of gravity of the LED display screen. Therefore, the rising center of gravity will reduce the stability of the device. In addition, the device cannot adjust the tilt angle of the LED display screen, and cannot make the LED display screen at the best tilt angle when facing the user. Therefore, the practicality is not very good and there is room for improvement. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a lifting structure for an LED display screen, which has the characteristics of improved practicality and stability.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a lifting structure for an LED display screen, comprising a shell and a lifting rod body, an LED display screen being installed inside the shell, a fixing plate being provided on the upper part of the lifting rod body, an adjusting device being provided on the right part of the fixing plate, the right part of the adjusting device being rotatably connected to a first connecting plate via a rotating shaft, several of the first connecting plates being connected to the shell, a bottom plate being provided on the lower part of the lifting rod body, and a supporting device being provided on the right part of the bottom plate for increasing the supporting area.

[0008] Furthermore, the adjusting device includes a plurality of first telescopic rods, and the left portions of the plurality of first telescopic rods are fixedly connected to the fixing plate.

[0009] Furthermore, the adjustment device also includes a second telescopic rod, the left portion of the second telescopic rod is rotatably connected to a plurality of second connecting plates via a rotating shaft, and the left portions of the plurality of second connecting plates are fixedly connected to the fixed plate.

[0010] Furthermore, the supporting device includes several third telescopic rods, and a group of brake wheels are provided at the lower part of the several third telescopic rods.

[0011] Preferably, intervals are provided between the brake wheels at the lower portions of the third telescopic rods.

[0013] (3) Beneficial effects

[0014] Compared with the existing technology, the present invention provides a lifting structure for an LED display screen, which has the following beneficial effects:

[0015] This LED display lifting structure adjusts the length of the second telescopic rod to be longer or shorter than the length of the first telescopic rod, thereby causing the LED display to tilt in different directions. When facing the user, the tilt angle is optimal, thereby improving practicality to a certain extent. Secondly, when the LED display is adjusted upward to a certain height, the third telescopic rod is stretched to increase the overall footprint of the base plate and the third telescopic rod, thereby improving stability and adjusting the center of gravity toward the third telescopic rod. Then, by adjusting the lengths of the first and second telescopic rods, the LED display is controlled to move in the direction of the extension of the third telescopic rod, so that the center of gravity of the LED display is close to the center of gravity position after the third telescopic rod is extended, thereby improving stability to a certain extent.

[0023] See also Figure 1-5The utility model discloses a lifting structure for an LED display screen, comprising a shell 1 and a lifting rod body 2. An LED display screen 3 is installed inside the shell 1. The lifting rod body 2 is used to adjust the height of the LED display screen 3. A fixing plate 4 is provided on the upper part of the lifting rod body 2. An adjusting device is provided on the right part of the fixing plate 4. The right part of the adjusting device is rotatably connected to a first connecting plate 5 through a rotating shaft. Several first connecting plates 5 are connected to the shell 1. The shell 1 is connected together through the first connecting plate 5, the adjusting device and the fixing plate 4. The adjusting device comprises several first telescopic rods 7. The left parts of the several first telescopic rods 7 are fixedly connected to the fixing plate 4. The first telescopic rod 7 is fixedly connected to the fixing plate 4. The first telescopic rod 7 is rotatably connected to the shell 1 through the first connecting plate 5. Thus, it is rotatably connected to the LED display screen 3. By adjusting the length of the first telescopic rod 7, the distance the LED display screen 3 moves to the right can be adjusted, thereby adjusting its own center of gravity to move to the right. The adjusting device also includes a second telescopic rod 8. The left part of the second telescopic rod 8 is rotatably connected to several second connecting plates 9 through a rotating shaft. The left parts of several second connecting plates 9 are fixedly connected to the fixed plate 4. The second telescopic rod 8 is rotatably connected to the housing 1 through the first connecting plate 5 and is rotatably connected to the fixed plate 4 through the second connecting plate 9. The length of the second telescopic rod 8 is adjusted. Then, when the length of the first telescopic rod 7 is not adjusted, the first telescopic rod 7 and the fixed plate 4 are in a right angle state. At this time, the second telescopic rod 8 is rotated in an oblique upward direction through the rotating shaft of the second connecting plate 9. The second telescopic rod 8 is moved to move, thereby driving the lower part of the housing 1 and the LED display screen 3 to rotate in the direction of tilting to the right, thereby adjusting the tilt angle of the LED display screen 3, or contracting the length of the second telescopic rod 8 to drive the lower part of the LED display screen 3 to rotate in the direction of tilting to the left, the lower part of the lifting rod body 2 is provided with a bottom plate 6, and the right part of the bottom plate 6 is provided with a supporting device for increasing the supporting area and improving the stability of the lifting structure of the LED display screen 3. The supporting device includes several third telescopic rods 10. When the height of the LED display screen 3 needs to be adjusted upward, the third telescopic rods 10 can be stretched and the overall length of the third telescopic rods 10 can be adjusted, thereby cooperating with the bottom plate 6 to increase the overall support area, thereby improving the stability of the lifting structure of the LED display screen 3. The lower part of the third telescopic rod 10 is provided with a group of brake wheels 11, which move on the ground to facilitate adjustment of the position of the lifting structure of the LED display screen 3.
