[0046] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below with reference to the accompanying drawings and through specific embodiments. Figure 1 The orientation is referenced.

[0047] Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0048] like Figure 1 and Figure 2 As shown, the present invention provides a modular wind-resistant frame, which includes a base 1 and at least one mounting frame 2. The base 1 is in a T-shaped structure to improve the stability of the wind-resistant frame. Specifically, the mounting frame 2 includes a first bracket module 21, a second bracket module 22 and a third bracket module 23. The first bracket module 21 includes a first column 211 and a first arm 212 connected to each other, and the first arm 212 is perpendicular to the first column 211. The second bracket module 22 includes a second column 221 and a second arm 222 connected to each other, and the second arm 222 is perpendicular to the second column 221. The third bracket module 23 includes a connecting column 231 and a connecting arm 232 connected to each other, and the connecting column 231 is perpendicular to the connecting arm 232. The first column 211, the connecting column 231 and the second column 221 are detachably connected in sequence. The first column 211 and the second column 221 are connected through the connecting column 231 to form a column structure. The first arm 212 and the second arm 222 are parallel to each other. There is a certain angle between the connecting arm 232 and the first arm 212, which is used to install LED display screen modules at the ends of each arm. The first bracket module 21 and the second bracket module 22 have the same structure, and only the installation position is different. When the number of mounting frames 2 is one, the first column 211 is detachably connected to the base 1, and an LED display screen module can be installed vertically. When the number of mounting frames 2 is multiple, the two mounting frames 2 are vertically stacked and installed, and the first column 211 of the mounting frame 2 located at the bottom is connected to the base 1, and the second column 221 of the mounting frame 2 located at the top of the two mounting frames 2 is detachably connected to the first column 211 of the mounting frame 2 located at the bottom. In theory, by vertically stacking the mounting frames 2, the LED display screen modules can be infinitely increased in the vertical direction, and the application is flexible and changeable, which improves the flexibility of the installation of the LED display screen modules, and the wind-resistant frame is suitable for a variety of occasions. The modularly designed mounting frame 2 is convenient, stable and effective to disassemble and assemble, which improves the efficiency of disassembly and assembly.

[0049] The wind-resistant frame of the present invention allows for flexible selection of the number of mounting brackets 2 to accommodate the installation of varying numbers of LED display modules. Furthermore, the modular design of the mounting brackets 2 facilitates assembly and disassembly, ensuring stability and efficiency, thereby improving assembly and disassembly efficiency and avoiding the need to assemble individual parts during assembly, which can lead to low assembly efficiency and the risk of parts being lost, damaged, or deformed. Furthermore, the modular design of the mounting brackets 2 allows the wind-resistant frame to be split into multiple modules, eliminating the situation where the wind-resistant frame is too large to be easily stored or transported.

[0050] like Figure 3 As shown, a first connecting mechanism 213 is provided at the lower end of the first column 211, and the first connecting mechanism 213 is detachably connected to the base 1. A second connecting mechanism 223 is provided at the upper end of the second column 221, and when two mounting frames 2 are connected, the second connecting mechanism 223 is used to detachably connect to the first connecting mechanism 213 to achieve connection between the mounting frames 2.

[0051] Furthermore, if Figure 4 and Figure 5 As shown, the first connecting mechanism 213 includes a first connecting rod 2131 and a first sleeve 2132. The first connecting rod 2131 is connected to the lower end of the first column 211, or the lower end portion of the first column 211 is directly used as the first connecting rod 2131. A first connecting rod 2133 is provided on the base 1. The first connecting rod 2131 and the first connecting rod 2133 are respectively connected to the two ends of the first sleeve 2132 in a one-to-one correspondence, thereby facilitating the assembly and disassembly of the first column 211 and the first bracket module 21. In a preferred embodiment, a blind hole is provided on the base 1, and the first connecting rod 2133 is disposed in the blind hole. The portion of the first sleeve 2132 inserted into the blind hole is connected to the first connecting rod 2133, thereby improving the stability of the installation of the first column 211.

[0052] like Figure 5As shown, the first connecting mechanism 213 also includes a first pin 2134 and a first spring 2135. The first sleeve 2132 and the first spring 2135 are both sleeved on the first connecting rod 2131, with the spring positioned between the first sleeve 2132 and the first connecting rod 2131. The upper end of the first spring 2135 abuts the upper end of the first sleeve 2132. The lower end of the first connecting rod 2131 is provided with a flange, and the lower end of the first spring 2135 abuts the flange, thereby compressing the first spring 2135 between the upper end of the first sleeve 2132 and the lower end of the first connecting rod 2131. A first J-shaped groove 2136 is symmetrically defined at the upper end of the first connecting rod 2133, and an I-shaped groove 2137 is symmetrically defined at the lower end of the first connecting rod 2131, corresponding to the notch of the first J-shaped groove 2136 on the first connecting rod 2133. The first pin shaft 2134 is arranged in the first sleeve 2132 along the radial direction of the first sleeve 2132. In the initial state, the first pin shaft 2134 is located in the I-shaped groove 2137 and abuts against the bottom of the I-shaped groove 2137 due to the force of the first spring 2135 on the first sleeve 2132. When the first column 211 is connected to the base 1, the first sleeve 2132 is pressed down to make it move downward along the axial direction of the first connecting rod 2131, and the first pin shaft 2134 is driven by the first sleeve 2132 to move from the I-shaped groove 2137 to the bottom of the first J-shaped groove 2136; the first sleeve 2132 is driven to rotate along the circumference of the first connecting rod 2131, thereby driving the first pin shaft 2134 to rotate in the first J-shaped groove 2136 to the curved part of the first J-shaped groove 2136. At this time, the first sleeve 2132 is acted upon by the force of the first spring 2135 to move upward along the curved part of the first J-shaped groove 2136 to the limit position, and the first pin shaft 2134 is clamped in the first J-shaped groove 2136. The first sleeve 2132 is restricted by the first pin shaft 2134 and has no The first sleeve 2132 is not able to rebound, and the lower end of the first sleeve 2132 is sleeved with the first connecting rod 2133 and locked with the first J-shaped groove 2136 through the first pin 2134, thereby achieving the docking of the first connecting rod 2131 and the first connecting rod 2133. When the first column 211 is separated from the base 1, the first sleeve 2132 is pressed down, and the first pin 2134 moves to the bottom of the first J-shaped groove 2136. The first sleeve 2132 is then rotated in the opposite direction until the first pin 2134 moves to the vertical part of the first J-shaped groove 2136. The first sleeve 2132 moves upward under the action of the first spring 2135, so that the first pin 2134 moves upward into the I-shaped groove 2137, restoring the initial state, and the first sleeve 2132 is separated from the first connecting rod 2133. The first column 211 and the base 1 are easy to disassemble and assemble. After the first column 211 is connected to the base 1, it has a self-locking function, which ensures stable installation.

[0053] like Figure 7As shown, the second connecting mechanism 223 includes a second connecting rod 2231, a second sleeve 2232, and a second spring. The second connecting rod 2231 is connected to the upper end of the second column 221, and the second sleeve 2232 is slidably mounted on the second connecting rod 2231. The second spring is mounted on the second connecting rod 2231 and abuts between the flange provided at the lower end of the second connecting rod 2231 and the upper end of the second sleeve 2232. In the first embodiment, the upper end of the second connecting rod 2231 is symmetrically provided with a second J-shaped groove 2235, which corresponds one-to-one with the J-shaped groove 2137 on the first connecting rod 2131. When the first column 211 is connected to the second column 221, the first sleeve 2132 is pressed down to make it move downward along the axial direction of the first connecting rod 2131, and the first pin shaft 2134 is driven by the first sleeve 2132 to move from the I groove 2137 to the bottom of the second J groove 2235. After the first pin shaft 2134 abuts against the upper end of the second sleeve 2232, the second sleeve 2232 is forced to move downward; the first sleeve 2132 is driven to rotate along the circumference of the first connecting rod 2131, thereby driving the first pin shaft 2134 to rotate in the second J groove 2235 to the curved part of the second J groove 2235. At this time, the first sleeve 2132 is subjected to the force of the first spring 2135 to move upward along the curved part of the second J groove 2235 to the limit position, and the first pin shaft 2134 is clamped in the second J groove 2235. The sleeve 2132 is restricted by the first pin 2134 and cannot rebound. The lower end of the first sleeve 2132 is sleeved with the second connecting rod 2231 and locked with the second J-shaped groove 2235 through the first pin 2134, so that the first connecting rod 2131 and the second connecting rod 2231 are connected. When the first column 211 is separated from the second column 221, the first sleeve 2132 is pressed down, and the first pin 2134 moves to the bottom of the second J-shaped groove 2235. Then, the first sleeve 2132 is rotated in the opposite direction until the first pin 2134 moves to the vertical part of the second J-shaped groove 2235. The first sleeve 2132 moves upward under the action of the first spring 2135, so that the first pin 2134 moves upward to the I-shaped groove 2137, restoring the initial state, and the first sleeve 2132 is separated from the second connecting rod 2231. Example 2, see Figure 7The upper end of the second connecting rod 2231 is symmetrically provided with connecting grooves that correspond to the I-shaped groove 2137 on the first connecting rod 2131. The connecting groove includes a vertical part and a horizontal part that are connected to each other. The upper end of the second sleeve 2232 is provided with a limiting groove 2234, and the limiting groove 2234 is located at the end of the horizontal part of the connecting groove. When the first sleeve 2132 drives the first pin 2134 to move from the I-shaped slot 2137 to the bottom of the vertical portion of the connecting slot, the first pin 2134 abuts against the upper end of the second sleeve 2232, forcing the second sleeve 2232 to move downward. The first sleeve 2132 is driven to rotate along the circumference of the first connecting rod 2131, and the first pin 2134 is driven to move along the transverse portion of the connecting slot to the limit position. At this time, the notch of the limiting slot 2234 is located directly below the first pin 2134. The second sleeve 2232 is forced upward by the force of the second spring, and the first pin 2134 is engaged in the limiting slot 2234 and cannot rotate, thereby locking the first pin 2134 and connecting and locking the first column 211 to the second column 221. The reverse operation can separate the first column 211 from the second column 221.

[0054] like Figure 6 As shown, the two ends of the connecting column 231 respectively slot into the upper end of the first column 211 and the lower end of the second connecting column 231. The connecting column 231 has a mounting slot 233, into which the connecting arm 232 is inserted and locked with a bolt for easy assembly and disassembly. Rotating the connecting column 231 changes the angle between the connecting arm 232 and the first arm 212, as well as between the connecting arm 232 and the second arm, to accommodate LED display modules of varying widths.

[0055] like Figures 1 to 3 As shown, the ends of the first arm 212 , the second arm 222 and the connecting arm 232 are all hinged with a connecting member 3 , and the connecting member 3 is connected to the LED display module.

[0056] like Figures 1 to 3 As shown, the base 1 includes a horizontally arranged and mutually perpendicular crossbeam 11 and a longitudinal beam 12. The end of the crossbeam 11 is connected to the middle of the longitudinal beam 12 through a connecting module 4. The first column 211 is detachably connected to the crossbeam 11. The base 1 has a stable structure and a strong anti-falling ability. Figure 5As shown, the connection module 4 includes a first connecting tube 41, a second connecting tube 42 and a third connecting tube 43. The first connecting tube 41 is connected to the crossbeam 11, and the third connecting tube 43 is connected to the longitudinal beam 12. The first end of the second connecting tube 42 is sleeved with the first connecting tube 41, and the second end of the second connecting tube 42 is sleeved with the third connecting tube 43. By replacing the second connecting tubes 42 of different lengths, the distance between the end of the crossbeam 11 and the longitudinal beam 12 is changed to match the change in the angle between the connecting arm 232 and the first support arm 212. While ensuring the connection between the LED display module and each arm, the bottom of the LED display module is always located on the longitudinal beam 12, thereby improving the stability and pressure resistance of the LED display module installation, and providing stable support for the upward stacking installation of the LED display module.

[0057] like Figure 2 and Figure 3 As shown, a plurality of locking members 13 and a plurality of positioning members 14 are provided on the longitudinal beam 12. The lower ends of the locking members 13 and the positioning members 14 are both connected to the longitudinal beam 12. The upper end of the positioning member 14 is sleeved with the lower frame of the LED display module. The upper end of the locking member 13 is detachably connected to the lower frame of the LED display module. In a preferred embodiment, the locking member 13 is vertically slidably sleeved in the through hole located on the crossbeam 11. The lower end of the locking member 13 is threadedly connected with an adjusting nut, and the upper end of the locking member 13 is provided with a locking circular hole and a bar hole. When the LED display module is installed, the locking member 13 is inserted into the corresponding locking hole on the LED display module, and a pin is inserted into the locking circular hole or the bar hole for locking. The LED display module is locked on the crossbeam 11 by adjusting the adjusting nut to tighten the locking member.

[0058] like Figure 2 As shown, a plurality of adjusting feet 15 are provided on the bottom surface of the base 1 for leveling the base 1 .
