[0030] like Figures 1 to 5 As shown, the embodiment of the utility model provides an arc-shaped installation and fixing structure for an LED display screen box, comprising: an arc tube 1 and an arc bar 2 inserted into the arc tube 1 in a sliding manner, a first fixing seat 3 is provided at the first end of the arc tube 1, and a second fixing seat 4 is provided at the second end of the arc bar 2 away from the first end of the arc tube 1; the first fixing seat 3 and the second fixing seat 4 are used to be connected to two adjacent LED display screen boxes respectively. Specifically, screw holes can be provided on the first fixing seat 3 and the second fixing seat 4 to be connected to the LED display screen box by bolts.

[0031] An adjustment window 5 is provided on the side of the arc tube 1, and a plurality of limit grooves 6 are provided on the side of the arc strip 2 facing the adjustment window 5; a limit member 7 is rotatably provided on the side of the arc tube 1, and when the limit member 7 is rotated to a first position, an end of the limit member 7 is away from the limit groove 6; when the limit member 7 is rotated to a second position, an end of the limit member 7 is inserted into one of the plurality of limit grooves 6 to limit the angle between the display planes of the two LED display screen boxes connected to the first fixing seat 3 and the second fixing seat 4.

[0032] Specifically, Figures 2 to 4 As shown, the limiting groove 6 can be triangular, trapezoidal or rectangular. Preferably, the limiting groove 6 is as follows Figure 4 In the triangle shown, the end of the limiting member 7 is an inclined surface that cooperates with the limiting groove 6, so that the limiting member 7 and the limiting groove 6 cooperate with each other to improve the stability of the limiting of the arc strip 2.

[0033] The utility model is based on the above-mentioned sliding-matched arc tube 1 and arc strip 2. The installer can adjust the angle between the first fixing seat 3 and the second fixing seat 4 by adjusting the length of the arc strip 2 inserted into the arc tube 1, and then adjust the angle between the display planes of the two LED display screen boxes connected by the first fixing seat 3 and the second fixing seat 4, thereby realizing the curvature of the spliced ​​arc display screen to improve its versatility in diversified demand scenarios.

[0034] In a preferred implementation of this embodiment, as Figure 4 and 5As shown, the adjustment window 5 is a strip opened along the axial direction of the arc tube 1, and the edge of the adjustment window 5 along its length direction may also be provided with a scale (not shown in the figure) so that the installer can understand the current angle between the first fixing seat 3 and the second fixing seat 4. The limiter 7 is arranged at the right end of the adjustment window 5. The limiter 7 includes an L-shaped member and a support 71; the L-shaped member includes a first support arm 72 and a second support arm 73, the second support arm is rotatably connected to the support 71 through a rotating shaft 74, and the end of the first support arm 72 is used to insert into one of the plurality of limit slots 6. A torsion spring 75 is sleeved on the rotating shaft 74, the first end of the torsion spring 75 abuts against the arc tube 1, and the second end of the torsion spring 75 abuts against the second support arm 73 of the L-shaped member.

[0035] The first fixing seat 3 is arranged to enclose the first end of the arc tube 1, and a spring 8 is provided in the inner cavity of the first end of the arc tube 1. The first end of the spring 8 is connected to the first fixing seat 3, and the second end of the spring 8 is connected to the first end of the arc strip 2. The spring 8 can be in a compressed state to provide a leftward thrust to the arc strip 2, or in an extended state to provide a rightward pulling force to the arc strip 2, so as to cooperate with the limiting member 7 to improve the stability of limiting the arc strip 2.

[0036] More preferably, the fixing structure further comprises a push seat 9, the push seat 9 passes through the adjustment window 5 and is connected to the arc strip 2, and the push seat 9 is arranged in the adjustment window 5 at one end away from the stopper 7. Specifically, the push seat 9 comprises a connecting column 91, a first end of the connecting column 91 is connected to the arc strip 2, and a second end of the connecting column 91 passes through the adjustment window 5 and extends to the outside of the arc tube 1 and expands to form a push-pull portion 92, so that the installer can adjust the position of the arc strip 2 in the arc tube 1 by pushing and pulling the push-pull portion 92.

[0037] Based on the above setting, when adjusting the angle of the fixed structure, the installer can hold the arc tube 1 with one hand and press the second arm 73 of the L-shaped piece with the thumb to make the end of the first arm 72 of the L-shaped piece away from the limit slot 6. At this time, use the other hand to slide the push seat 9 left and right. After adjusting the arc strip 2 to the appropriate position, release the L-shaped piece and insert the first arm 72 of the L-shaped piece into the corresponding limit slot. The angle between the first fixing seat 3 and the second fixing seat 4 can be completed, and then it can be used for the subsequent arc installation of the LED display box. More specifically, based on Figure 4In the fixed structure shown, the angle between the first fixing seat 3 and the second fixing seat 4 is 180 degrees in the current state; based on the current state, the arc strip 2 is moved to the left so that the first end of the arc strip 2 is away from the first end of the arc tube 1, so that the angle between the first fixing seat 3 and the second fixing seat 4 can be less than 180 degrees, thereby making the arc display surface formed by the final splicing and installation a concave surface; conversely, based on the current state, the arc strip 2 is moved to the right so that the first end of the arc strip 2 is close to the first end of the arc tube 1, so that the angle between the first fixing seat 3 and the second fixing seat 4 can be greater than 180 degrees, thereby making the arc display surface formed by the final splicing and installation a convex surface. That is, based on the fixing mechanism provided in this embodiment, not only can the curvature of the arc display screen be adjusted, but also the convex and concave surfaces of the arc display screen can be switched.

[0038] In addition, the embodiment of the utility model also provides an LED display screen, including multiple LED display screen boxes and the above-mentioned fixed structure, and two adjacent LED display screen boxes are connected by the fixed structure to splice multiple LED display screen boxes into a display surface that is approximately arc-shaped. It should be noted that usually large-scale LED display screens also require a frame or framework to provide support for the LED display screen box, which can be achieved using existing technology. For example, the LED display screen boxes can be stacked, and the adjacent LED display screen boxes can be connected by the above-mentioned fixed structure to form a combination, and then the frame is used to reinforce and support the combination as a whole.
