[0027] Referring to Figure 1 , an embodiment of the present utility model includes an LED display screen 120 system, and the LED display screen 120 system is formed by splicing a plurality of LED display screen units 100.

[0028] Referring to Figure 2 , an embodiment of the present utility model includes an LED display screen unit 100. The LED display screen unit 100 includes an LED display screen 120 and a wind-resistant frame 110. The wind-resistant frame 110 is connected to the back side of the LED display screen 120, and the wind-resistant frame 110 has two states of being opened and folded.

[0029] Referring to Figures 3 - 5 , the embodiment of the present utility model specifically introduces the wind-resistant frame 110. The wind-resistant frame 110 includes a support rod 111, a first connecting rod 112 and a second connecting rod 113. One end of the first connecting rod 112 is connected to the support rod 111, and the other end of the first connecting rod 112 is rotatably connected to one side of the back of the LED display screen 120. One end of the second connecting rod 113 is rotatably connected to the support rod 111, and the other end of the second connecting rod 113 is rotatably connected to the other side of the back of the LED display screen 120. The second connecting rod 113 is a telescopic rod. The telescopic rod includes a sleeve 1131 and an inner tube 1132. The inner tube 1132 is slidably connected to the sleeve 1131. A locking member is provided at the bottom of the sleeve 1131, and the locking member is used to fix the inner tube 1132 and the sleeve 1131.

[0030] When the wind-resistant frame 110 is opened, the wind-resistant frame 110 rotates around the connection between the first connecting rod 112 and the LED display screen 120, so that the support rod 111 moves away from the LED display screen 120. During this process, the inner tube 1132 slides in the sleeve 1131 to extend the second connecting rod 113 to adapt to the distance between the support rod 111 and the LED display screen 120. The inner tube 1132 and the sleeve 1131 are fixed by a locking member, thereby fixing the position of the opened wind-resistant frame 110. Conversely, when the locking member is opened and the second connecting rod 113 shortens, the support rod 111 moves closer to the LED display screen 120 to realize the folding of the wind-resistant frame 110.

[0031] Further, the locking member includes a indexing pin 1133 provided on the sleeve 1131. A through hole for the pin rod of the indexing pin 1133 to pass through is provided on the sleeve 1131. A plurality of pin holes cooperating with the indexing pin 1133 are provided on the inner tube 1132. The plurality of pin holes are evenly spaced along the length direction of the inner tube 1132. For example, a pin hole is provided at each end of the inner tube 1132. When the second connecting rod 113 extends to open the wind-resistant frame 110, the pin rod of the indexing pin 1133 passes through the through hole and is caught in the pin hole at the end of the inner tube 1132 close to the support rod 111, thereby preventing the inner tube 1132 from sliding relative to the sleeve 1131 and fixing the two; when the second connecting rod 113 shortens to fold the wind-resistant frame 110, the pin rod of the indexing pin 1133 passes through the through hole and is caught in the pin hole at the end of the inner tube 1132 close to the LED display screen 120, fixing the inner tube 1132 and the sleeve 1131; when the inner tube 1132 and the sleeve 1131 need to slide, pull the indexing pin 1133 downward to make its pin rod leave the pin hole.

[0032] Furthermore, a limiting groove 1134 is provided on the side wall of the inner tube 1132 along its length direction, and a limiting pin 1135 is provided on the sleeve 1131. The limiting pin 1135 is slidably connected in the limiting groove 1134. When the limiting pin 1135 abuts against the bottom of the two ends of the limiting groove 1134, the positioning of the indexing pin 1133 and the pin hole is realized, enabling precise positioning of the two, so as to facilitate quick fixing after the wind-resistant frame 110 is opened or folded.

[0033] In this embodiment, refer to Figure 4, the first connecting rod 112 and the support rod 111 are connected by a first fixing sleeve 118. The first fixing sleeve 118 is sleeved on the support rod 111, and then a fixing pin 1111 passes through the first fixing sleeve 118 and the support rod 111 to realize the fixed connection between the first fixing sleeve 118 and the support rod 111. The sleeve 1131 of the second connecting rod 113 and the support rod 111 are connected by a second fixing sleeve 119. The second fixing sleeve 119 is rotatably sleeved on the support rod 111. Limiting sleeves 1110 are fixedly connected to both sides of the second fixing sleeve 119 on the support rod 111. By passing a fixing pin 1111 through the limiting sleeve 1110 and the support rod 111, the fixed connection between the limiting sleeve 1110 and the support rod 111 is realized, and the two limiting sleeves 1110 prevent the second fixing sleeve 119 from displacing in the vertical direction.

[0034] In this embodiment, referring to Figure 4 and Figure 5 , both between the first connecting rod 112 and the LED display screen 120 and between the inner tube 1132 of the second connecting rod 113 and the LED display screen 120 are rotatably connected through a hinge structure.

Locking holes are provided on both the hinge seat 1113 and the connecting rotating shaft 1112. The quick-release pin 116 is inserted into the locking holes, so that the connecting rotating shaft 1112 is connected to the hinge seat 1113, and the connecting rotating shaft 1112 and the hinge seat 1113 are rotatably connected based on the quick-release pin 116. In this way, when assembling and disassembling the LED display screen 120 and the wind-resistant frame 110, only need to insert or remove the quick-release pin 116, which greatly improves the assembly efficiency.

[0035] Further, a connecting rope 117 is provided on the quick-release pin 116. One end of the connecting rope 117 away from the quick-release pin 116 is connected to the LED display screen 120, which can avoid the need to find another place to store the quick-release pin 116 after it is removed and prevent the quick-release pin 116 from being lost.

[0036] In this embodiment, referring to Figure 1 and Figure 3 , a plurality of the first connecting rods 112 and the second connecting rods 113 are provided, and the first connecting rods 112 and the second connecting rods 113 are arranged alternately in the vertical direction, which can improve the stability of the wind-resistant frame 110. Additionally, it can also be used as a climbing frame in the LED display screen 120 system.

[0037] In this embodiment, referring toFigure 1 , Figure 3 and Figure 4 , a first connection part 114 is provided at the upper end of the support rod 111, and a second connection part 115 is provided at the lower end of the support rod 111. In the LED display screen 120 system, when two adjacent LED display screen units 100 are spliced, the second connection part 115 is connected to the first connection part 114. Specifically, the first connection part 114 includes a groove provided at the upper end of the support rod 111, a connection nut is sleeved on the groove, and the connection nut can move up and down within the range of the groove.
