[0002] LED screens are a type of display device with audio and video functions in modern society. They are often assembled by combining multiple sets of light-emitting diodes, and the patterns are changed by the light-emitting and turning-off of the diodes.

[0003] In the current technology, during the assembly of outdoor LED screens, it is often necessary to first construct a metal frame to constrain the entire LED screen and maintain its stability during normal use. Existing screen supports are mainly made of steel trusses as the frame, with pre-embedded concrete foundations, and connected to the columns using anchor bolts. Alternatively, trusses can be constructed on the exterior walls of the permanent structure, with the load-bearing members of the truss pre-embedded in the permanent structure.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-7 As shown, an LED large screen bracket includes a large screen frame 1; multiple sets of limiting blocks 11 are provided at one node of the large screen frame 1; steel wire ropes 13 are provided at the ends of the limiting blocks 11; pins 12 are fixedly connected to the ends of the steel wire ropes 13; a pair of connecting plates 15 are fixedly connected to the side wall of the limiting blocks 11; connecting blocks 16 are fixedly connected to the ends of the connecting plates 15; first rotating shafts 17 are hinged to both the upper and lower ends of the connecting blocks 16; a collar 14 is provided on the side wall of the pair of first rotating shafts 17; the collar 14 passes through the large screen frame 1 and the first rotating shafts 17 in an arc shape to connect them; a pressing rod 18 is provided at the end of the collar 14; a pair of blocking plates 19 are slidably connected to the side wall of the first rotating shafts 17; the pair of blocking plates 19 are connected by an elastic band; the pressing rod 18 and the blocking plates 19 are in contact; during operation, after the staff assembles the large screen frame 1, the collar 14 can be bypassed around the large screen frame 1. The device is then connected to the first rotating shaft 17. The support effect of the pressing rod 18 on the barrier plate 19 maintains the stability of the collar 14 inside the first rotating shaft 17. Subsequently, through the connection effect of the pin 12, the large screen frame 1 can be limited by the pulling effect of the steel wire rope 13 after it is inserted into the ground. When it needs to be disassembled, the barrier plate 19 can be inserted into the pressing rod 18 by squeezing the pressing rod 18 under the action of the elastic band, so that the collar 14 can be removed from the range of the first rotating shaft 17. This step utilizes the detachability between the collar 14 and the first rotating shaft 17, which makes it easy for workers to quickly complete the combination operation between the limiting block 11, the pin 12, and the steel wire rope 13 during the assembly of the large screen frame 1. The positioning of the extension plate 23 and the pulling effect of the steel wire rope 13 increase the wind resistance of the large screen frame 1, increase the stability of the equipment, and reduce the possibility of tipping over.

[0031] Please see Figure 4-5As shown, a first sliding groove 2 is formed on the side wall of the limiting block 11; a sliding rod 21 is slidably connected inside the first sliding groove 2; the end of the steel wire rope 13 is fixed to the side wall of the sliding rod 21; a limiting ring 22 is slidably connected inside the first sliding groove 2; the limiting ring 22 and the connecting plate 15 are connected by a spring; the end of the sliding rod 21 is fixed to the side wall of the limiting ring 22; an extension plate 23 is fixed to the side wall of the limiting ring 22; during operation, as the steel wire rope 13 pulls on the large screen frame 1, the sliding rod 21 can pass through the first sliding groove 2 formed on the limiting block 11. During the sliding motion, the spring connection between the limiting ring 22 and the connecting plate 15 provides elastic support. When the large screen frame 1 sways in strong winds, the elastic support between the connecting plate 15 and the limiting ring 22 can buffer the steel wire rope 13. This step of the elastic support between the limiting ring 22 and the connecting plate 15 can provide a certain buffering effect for the steel wire rope 13 in cold northern temperatures, reducing the movement of the frozen steel wire rope 13 when the large screen frame 1 sways slightly, thus preventing the steel wire rope 13 from breaking due to freezing.

[0032] Please see Figure 3-5 As shown, a second sliding groove 3 is provided in the middle of the connecting block 16; a connecting rod 31 is fixedly connected to the side wall of the extension plate 23; the end of the connecting rod 31 slides through the second sliding groove 3; a pair of connecting straps 32 are fixedly connected to the corresponding position on the side wall of the collar 14; a fixing plate 33 is fixedly connected to the corresponding position in the middle of the collar 14; the ends of the pair of connecting straps 32 are respectively connected through the fixing plate 33 and the end of the connecting rod 31; during operation, when the limiting ring 22 moves, the limiting ring 22 will drive the connecting rod 31 to move, thereby providing a corresponding pulling effect on the connecting straps 32. The collar 14, fitted onto the large screen frame 1, deforms under the pulling effect of the connecting belt 32, wrapping around the side wall of the large screen frame 1 and reducing the gap between the collar 14 and the large screen frame 1. This step utilizes the movement effect of the limiting ring 22 to drive the connecting belt 32 to pull and deform the collar 14, reducing the possibility of slippage between the large screen frame 1 and the collar 14 due to the gap between them when the large screen frame 1 shakes, thus affecting the connection relationship between the collar 14 and the large screen frame 1 and improving the connection stability between the collar 14 and the large screen frame 1.

[0033] Please see Figure 3As shown, the first rotating shaft 17 has a third sliding groove 4 at its end; the collar 14 has a positioning rod 41 fixedly connected to its end; the first rotating shaft 17 has a fourth sliding groove 42 on its side wall; the collar 14 passes through the fourth sliding groove 42 and contacts the side wall of the positioning rod 41; the pressing rod 18 and the blocking plate 19 are both connected inside the positioning rod 41; during operation, when the worker is installing the collar 14, the positioning rod 41 installed on the end of the collar 14 can be inserted into the side wall of the first rotating shaft 17. Through the circular arrangement of the first rotating shaft 17 and the positioning rod 41, the stability of the positioning rod 41 inside the first rotating shaft 17 is maintained. This step, by utilizing the connection between the positioning rod 41 and the first rotating shaft 17, can reduce the occurrence of the collar 14 detaching from the first rotating shaft 17, and improve the stability of the equipment during use. At the same time, the circular arrangement between the positioning rod 41 and the first rotating shaft 17 can assist the worker in disassembling and assembling the equipment, improving its portability.

[0034] Please see Figure 6 As shown, each of the multiple sets of pins 12 has a No. 5 sliding groove 51 at its bottom; a pressing plate 5 is slidably connected inside the No. 5 sliding groove 51; the pressing plate 5 and the No. 5 sliding groove 51 are connected by a telescopic rod 52; multiple sets of No. 6 sliding grooves 53 are opened on the side wall of the pin 12; the No. 6 sliding groove 53 and the No. 5 sliding groove 51 are connected; a No. 2 rotating shaft 54 ​​is hinged to the bottom of each of the multiple sets of No. 6 sliding grooves 53; the No. 6 sliding groove 53 and the No. 2 rotating shaft 54 ​​are connected by a torsion spring; a pair of side plates 55 are fixed to the side wall of the No. 2 rotating shaft 54; the pair of side plates 55 are arranged at 90 degrees; during operation, as the pin 12 is inserted into the ground, the pressing plate 5, under the support of the telescopic rod 52... It can move inside the fifth chute 51. At this time, as the soil applies pressure to the extrusion plate 5, the side wall of the extrusion plate 5 will come into contact with the side walls of multiple sets of side plates 55. Under the extrusion effect, the side plates 55 will rotate through the second rotating shaft 54, causing one side of the side plate 55 to unfold towards the outer side wall of the pin 12 and come into contact with the underground soil. This step utilizes the movable effect of the extrusion plate 5. During the process of the pin 12 entering the soil, the extrusion effect of the extrusion plate 5 will drive the side plates 55 to rotate and unfold towards both sides of the pin 12, forming an angle with the side wall of the pin 12, increasing the contact area between the pin 12 and the soil, providing a blocking effect for the upward movement of the pin 12, and increasing the fixing effect.

[0035] Please see Figure 6-7As shown, sealing plates 61 are fixedly connected to the top of each of the six sets of sliding grooves 53; an arc plate 6 is fixedly connected between each pair of side plates 55; the arc plate 6 slides in the middle of the sealing plate 61; during operation, as the side plates 55 rotate under the pressure of the pressing plate 5, the arc plate 6 installed on the side wall of the side plate 55 can pass through the sealing plate 61. At this time, the blocking effect provided by the arc plate 6 can reduce the entry of soil into the five sliding grooves 51, and at the same time reduce the contact between soil and the second rotating shaft 54. This step utilizes the zoning effect of the arc plate 6 to reduce the entry of soil into the five sliding grooves 51 and cause blockage, and at the same time reduce the direct contact between soil and the second rotating shaft 54, maintaining the rotational stability of the second rotating shaft 54.

[0036] Please see Figure 7 As shown, the pin 12 is hinged to three rotating shafts 71 on both sides away from the side plate 55; the three rotating shafts 71 and the side walls of the pin 12 are connected by torsion springs; a support plate 7 is fixedly connected to the side wall of the three rotating shafts 71; a support ball 72 is fixedly connected to the side wall of the pin 12 below the three rotating shafts 71; during operation, when the pin 12 is inserted into the ground soil, the support plate 7 will leave a gap with the side wall of the pin 12 under the support of the support ball 72. When the support plate 7 comes into contact with the ground soil, the gap with the pin 12 allows the soil to enter, causing the support plate 7 to unfold outward. This step utilizes the supporting effect of the support ball 72 to allow the support plate 7 to unfold to both sides during the process of fixing the pin 12 in the soil through the squeezing effect of the soil, increasing the contact area between the support plate 7 and the soil, thereby increasing the limiting effect on the pin 12, increasing the stability of the pin 12 after it is inserted into the soil, and improving the connection effect with the large screen frame 1.

[0037] Please see Figure 6 As shown, the bottom end of the extrusion plate 5 has an arc-shaped groove 81; both ends of the arc-shaped groove 81 are hinged to a base plate 8; the base plate 8 and the arc-shaped groove 81 are connected by a torsion spring; magnets are fixed to the bottom end of the pin 12 and inside the base plate 8; during operation, after the pin 12 is inserted into the ground, as the extrusion plate 5 moves, the distance between the bottom of the pin 12 and the base plate 8 shortens. At this time, the magnets inside will cause the pair of base plates 8 to separate from each other under the magnetic attraction effect, creating a gap that allows soil to enter. This step utilizes the presence of the base plate 8 at the bottom of the extrusion plate 5, which, together with the magnetic attraction effect, causes the base plate 8 to unfold to both sides, allowing soil to enter the arc-shaped groove 81, increasing the friction between the extrusion plate 5 and the soil, and driving the extrusion plate 5 to move smoothly.

[0038] Please see Figure 7As shown, multiple sets of hook plates 9 are fixed to the side wall of the support plate 7 near the pin 12; the hook plates 9 are arc-shaped and the bending direction is towards the support ball 72; during operation, when the support plate 7 is in contact with the ground, the multiple sets of hook plates 9 installed on the side wall of the support plate 7 can use their bending effect to hook up the soil. When the pin 12 moves, the soil fills the gap between the hook plates 9 and the support plate 7. This step, using the multiple sets of hook plates 9 installed on the side wall of the support plate 7, can increase the friction between the pin 12 and the soil, improve the stability of the pin 12, and thus increase the pulling effect on the wire rope 13, maintain the limiting effect on the large screen frame 1, and improve stability.

[0039] Please see Figure 4 As shown, the outer sidewalls of multiple sets of steel wire ropes 13 are all covered with anti-freezing sleeves 101. During operation, when the steel wire ropes 13 are in cold weather in the north, the anti-freezing sleeves 101 can reduce the direct contact between the steel wire ropes 13 and the air, and reduce the freezing phenomenon on the surface of the steel wire ropes 13. This step utilizes the protective effect of the anti-freezing sleeves 101 to reduce the condensation caused by moisture on the surface of the steel wire ropes 13, improve the mobility of the steel wire ropes 13 in cold weather, and reduce the possibility of breakage during shaking due to freezing.

[0040] Working principle: After the staff assembles the large screen frame 1, the collar 14 can be bypassed by the large screen frame 1 and connected to the first rotating shaft 17. The support effect of the pressing rod 18 on the barrier plate 19 maintains the stability of the collar 14 within the first rotating shaft 17. Then, through the connection effect of the pin 12, the steel wire rope 13 can limit the large screen frame 1 after it is inserted into the ground. When disassembly is required, the pressing rod 18 can be squeezed to insert the barrier plate 19 into the pressing rod 18 under the action of the elastic band, allowing the collar 14 to move out of the area of ​​the first rotating shaft 17. During the pulling process of the steel wire rope 13 on the large screen frame 1, the sliding rod 21 can open through the limit block 11. The first slide 2 slides, and the spring connection between the limiting ring 22 and the connecting plate 15 provides elastic support. When the large screen frame 1 sways in strong winds, the elastic support between the connecting plate 15 and the limiting ring 22 cushions the steel wire rope 13. As the limiting ring 22 moves, it drives the connecting rod 31 to shift, thus providing a corresponding pulling effect on the connecting belt 32. At this time, the collar 14 fitted onto the large screen frame 1 deforms under the pulling effect of the connecting belt 32, wrapping around the side wall of the large screen frame 1 and reducing the gap between the collar 14 and the large screen frame 1. During the installation of the collar 14, the end of the collar 14 is installed... The positioning rod 41 can be inserted into the side wall of the first rotating shaft 17. The circular arrangement of the first rotating shaft 17 and the positioning rod 41 maintains the stability of the positioning rod 41 inside the first rotating shaft 17. During the insertion of the pin 12 into the ground, the extrusion plate 5, supported by the telescopic rod 52, can move within the fifth chute 51. At this time, as the soil applies pressure to the extrusion plate 5, the side wall of the extrusion plate 5 will contact the side walls of multiple sets of side plates 55, causing the side plates 55 to rotate under the extrusion effect via the second rotating shaft 54. This causes one side of the side plate 55 to unfold towards the outer side wall of the pin 12 and contact the underground soil. During the rotation of the side plate 55 under the extrusion pressure of the extrusion plate 5, the arc plate 6 installed on the side wall of the side plate 55 can... The material passes over the sealing plate 61. At this time, the blocking effect provided by the arc plate 6 reduces the amount of soil entering the fifth chute 51 and also reduces the contact between the soil and the second rotating shaft 54. During the insertion of the pin 12 into the ground soil, the support plate 7, supported by the support ball 72, will leave a gap between itself and the side wall of the pin 12. When the support plate 7 contacts the ground soil, the gap with the pin 12 allows soil to enter, causing the support plate 7 to unfold outwards. After the pin 12 is inserted into the ground, as the pressing plate 5 moves, the distance between the bottom of the pin 12 and the base plate 8 shortens. At this time, the internal magnets, under the magnetic attraction effect, will cause the pair of base plates 8 to disengage, creating a gap that allows soil to enter. During the contact between the support plate 7 and the ground...Multiple sets of hook plates 9 installed on the side wall of the support plate 7 can use their bending effect to hook up soil. As the pin 12 moves, the soil fills the gap between the hook plates 9 and the support plate 7. When the wire rope 13 is in cold northern weather, the cold-proof sleeve 101 covering the outside of the wire rope 13 can reduce the direct contact between the wire rope 13 and the air, reducing the freezing phenomenon on the surface of the wire rope 13.
