When forming the ball screen, multiple steel frames 2 and multiple LED screen bodies 1 are required, both of which are arc-shaped structures. When assembling, multiple LED screen bodies 1 are staggered and installed to form a seamless structure and lock each other. The mounting mechanism 3 is arranged between the LED screen body 1 and the steel frame 2, and the push mechanism 4 is arranged on the steel frame 2; wherein the mounting mechanism 3 includes a fixing rod 31, a slot 32 and a trapezoidal rod 33, and the trapezoidal rod 33 is slidably connected to the steel frame 2, a fixing rod 31 is fixedly installed on the back of the LED screen body 1, and one end passes through the front of the steel frame 2 and extends to the inside of the steel frame 2. A slot 32 is provided on the outer wall of the fixing rod 31, and one end of the trapezoidal rod 33 with an inclined surface is inserted into the inside of the slot 32. The fixing rod 31 is slidably connected to the steel frame 2, and a spring 35 is sleeved on the outer wall of the trapezoidal rod 33. The spring 35 can drive the trapezoidal rod 33 to reset. One end of the trapezoidal rod 33 is fixedly connected to a connecting piece 34. The two ends of the spring 35 are respectively fixedly connected to the outer wall of the steel frame 2 and the outer wall of the connecting piece 34. The connecting piece 34 is provided to enable the spring 35 to play a role.

[0023] Specifically, by aligning the fixing rod 31 and inserting it into the interior of the steel frame 2, the end of the fixing rod 31 will squeeze the inclined surface of the trapezoidal rod 33 during the insertion process, and the trapezoidal rod 33 will be pressed away from the fixing rod 31 until the slot 32 is aligned with the trapezoidal rod 33. The trapezoidal rod 33 will bounce into the slot 32 under the action of the spring 35 to complete the installation of the LED screen body 1, making the LED ball screen easy to assemble without the aid of tools, providing convenience for the staff and improving the efficiency of assembly.

[0024] like Figure 3-4 As shown, the pushing mechanism 4 includes a push rod 41, a connecting rod 42 and a spring 43. The push rod 41 penetrates the steel frame 2 and is slidably connected to the steel frame 2, and the connecting rod 42 is fixedly installed at one end of the push rod 41. One end of the spring 43 is fixedly connected to the outer wall of the steel frame 2, and the other end is fixedly connected to the outer wall of the connecting rod 42. By setting the push rod 41, the connecting piece 34 can be pushed, and the spring 43 can drive the push rod 41 to reset. The outer wall of the connecting rod 42 is rotatably connected to a rotating plate 44, and the outer wall of the rotating plate 44 is fixedly connected to a sliding rod 45. By setting the rotating plate 44, the sliding rod 45 can be driven to rotate. 2 is fixedly installed with a limit plate 46 on the outer wall, and a sliding hole 47 and a clamping hole 48 are opened on the limit plate 46. One end of the slide rod 45 is slidably connected to the inside of the slide hole 47. By setting the clamping hole 48, the top rod 41 can be prevented from resetting after the slide rod 45 is rotated into it. The outer wall of the steel frame 2 is fixedly connected with an arc-shaped cross beam 5, and the outer wall of the arc-shaped cross beam 5 is fixedly connected with a sealing strip 6. The arc-shaped cross beam 5 is provided to improve the strength of the steel structure of the ball screen. By providing the sealing strip 6, the assembly seam formed by the multiple LED screen bodies 1 that are misaligned and interlocked can be further sealed to improve the sealing of the ball screen.

The turn plate 44 is pressed until it moves to the maximum distance, and then the turn plate 44 is rotated to drive the slide bar 45 to rotate and engage in the inside of the slot 48 to limit the slide bar 45. In this way, there is no need to press the turn plate 44 all the time, and the trapezoidal rod 33 can be kept in a disengaged state, which facilitates the disassembly and maintenance of the LED screen body 1.

[0026] Furthermore, the LED ball curtain is composed of multiple LED screen bodies 1 to form a spherical shape.

The present application only draws the installation structure of a single LED screen body 1, which is similarly installed when formed as a whole.

[0027] The working principle of the utility model is as follows: when assembling the LED screen body 1, the fixing rod 31 is aligned and inserted into the interior of the steel frame 2. During the insertion process of the fixing rod 31, the end portion will squeeze the inclined surface of the trapezoidal rod 33, and the trapezoidal rod 33 will be pressed away from the fixing rod 31 until the slot 32 is aligned with the trapezoidal rod 33. The trapezoidal rod 33 is bounced into the interior of the slot 32 under the action of the spring 1 35 to complete the installation of the LED screen body 1, making the LED ball screen easy to assemble without the aid of tools, providing convenience for the staff and improving the efficiency of assembly. By pressing the rotating plate 44, the connecting rod 42 drives the top rod 41 to push the connecting piece 34, and the connecting piece 34 drives the trapezoidal rod 33 to disengage from the slot 32 to disassemble the LED screen body 1. Press the rotating plate 44 until it moves to the maximum distance, and then rotate the rotating plate 44 to drive the sliding rod 45 to rotate and engage in the interior of the locking hole 48 to limit the sliding rod 45, so that the trapezoidal rod 33 can be kept in a disengaged state without having to press the rotating plate 44 all the time, which is convenient for the disassembly and maintenance of the LED screen body 1.
