[0020] like Figure 1-3As shown, a spherical frame of a full-view spherical screen LED display spherical screen includes an arc rod 1, a mounting plate 2 and an assembly mechanism 3. The mounting plate 2 is arranged at the end of the arc rod 1, and the assembly mechanism 3 is arranged on the arc rod 1 and the mounting plate 2, and a groove is opened on the mounting plate 2; the assembly mechanism 3 includes an insertion rod 31, a hole 32, a fixing rod 33 and a circular plate 34, the insertion rod 31 is welded to the end of the arc rod 1, one end of the insertion rod 31 passes through the outer wall of the mounting plate 2 and extends to the inside of the groove, and the insertion rod 31 is movably connected with the mounting plate 2, the hole 32 is opened on the insertion rod 31, and the fixing rod 33 is fixedly installed on the circular plate 34. The outer wall of the plate 34 is connected to the hole 32 through the hole 32 for sliding connection. When assembling the spherical frame, multiple arc rods 1 need to be used to cooperate with two mounting plates 2. Multiple arc rods 1 are arranged in an equidistant circular array around the mounting plate 2.

There are two mounting plates 2, which are respectively located at the two ends of the arc rod 1. A limit rod 35 is fixedly installed at one end of the inner wall of the groove away from the opening. The limit rod 35 penetrates the circular plate 34 and is slidably connected to the circular plate 34. One end of the limit rod 35 is fixedly connected to a round block 36. The outer wall of the limit rod 35 is sleeved with a spring 37, and the two ends of the spring 37 are respectively fixedly connected to the outer wall of the round block 36 and the outer wall of the circular plate 34. The circular plate 34 can be driven to reset by setting the spring 37, and the circular plate 34 can be reset by setting the limit rod 35. 34 can move up and down stably. Two connecting rods 38 are fixedly connected to the top of the circular plate 34. One end of the two connecting rods 38 is fixedly installed with a connecting plate 39. By setting the connecting plate 39, the circular plate 34 can be driven to move when pulled. A limiting groove 310 is provided on the inner wall of the groove. One end of the sliding rod 311 is fixedly connected to the outer wall of the circular plate 34, and the other end of the sliding rod 311 is slidably connected to the inside of the limiting groove 310.

[0021] Specifically, when assembling the spherical frame of the full-field spherical screen LED display spherical screen, the insertion rods 31 on the multiple arc rods 1 are inserted into the groove through the mounting plate 2, and the fixing rods 33 are passed through the holes 32 to fix the insertion rods 31. The assembly of the shoe frame can be completed. The operation is simple and convenient, and there is no need to use a large number of bolts, which improves the efficiency of assembly and reduces the workload of the staff. By pulling the connecting plate 39, the connecting plate 39 pulls the circular plate 34 through the connecting rod 38, and the circular plate 34 drives the fixing rod 33 to disengage from the hole 32, the restriction of the insertion rod 31 can be released, and the disassembly of the arc rod 1 is convenient.

[0022] like Figure 2 As shown, a limiting mechanism 4 is provided on the mounting disk 2, and the number of limiting mechanisms 4 on each mounting disk 2 is two and they are arranged relatively to each other. The limiting mechanism 4 includes an L-shaped rod 41 and a trapezoidal rod 42, the trapezoidal rod 42 is slidably connected to the mounting disk 2, the L-shaped rod 41 is fixedly mounted on the outer wall of the connecting plate 39, and one end of the L-shaped rod 41 is provided with an inclined surface, and the inclined surface on the trapezoidal rod 42 can be squeezed by providing the L-shaped rod 41 with an inclined surface, one end of the trapezoidal rod 42 is fixedly connected with a disc 43, the outer wall of the trapezoidal rod 42 is provided with a spring 2 44, and the two ends of the spring 2 44 are respectively fixedly connected to the outer wall of the disc 43 and the outer wall of the mounting disk 2, and the trapezoidal rod 42 can be driven to reset by providing the spring 2 44.

[0023] Specifically, when assembling the arc rod 1 onto the mounting plate 2, the connecting plate 39 is pulled to drive the L-shaped rod 41 to move. The inclined surface on the L-shaped rod 41 will squeeze the inclined surface of the trapezoidal rod 42. The trapezoidal rod 42 moves under pressure, causing the L-shaped rod 41 to continue to move until the inclined surface of the L-shaped rod 41 no longer squeezes the inclined surface of the trapezoidal rod 42. The trapezoidal rod 42 is reset under the action of the spring 2 44. The trapezoidal rod 42 limits the L-shaped rod 41 to prevent the circular plate 34 from resetting, so that the spring 1 37 remains in a stretched state, which facilitates the disassembly and assembly of the arc rod 1 without having to pull the circular plate 34 all the time.

[0024] The working principle of the utility model is as follows: when assembling the spherical frame of the full-field spherical screen LED display spherical screen, the insertion rods 31 on the multiple arc-shaped rods 1 are inserted into the groove through the mounting plate 2, and then the fixing rods 33 are passed through the holes 32 to fix the insertion rods 31, and the assembly of the shoe frame can be completed. The operation is simple and convenient, and there is no need to use a large number of bolts, which improves the efficiency of assembly and reduces the workload of the staff. By pulling the connecting plate 39, the connecting plate 39 pulls the circular plate 34 through the connecting rod 38, and the circular plate 34 drives the fixing rod 33 to disengage from the hole 32 to release the restriction of the insertion rod 31. The system facilitates the disassembly of the arc rod 1. When assembling the arc rod 1 onto the mounting plate 2, the connecting plate 39 is pulled to drive the L-shaped rod 41 to move. The inclined surface on the L-shaped rod 41 will squeeze the inclined surface of the trapezoidal rod 42. The trapezoidal rod 42 moves under pressure, causing the L-shaped rod 41 to continue to move until the inclined surface of the L-shaped rod 41 does not squeeze the inclined surface of the trapezoidal rod 42. The trapezoidal rod 42 is reset under the action of the spring 2 44. The trapezoidal rod 42 limits the L-shaped rod 41 to prevent the circular plate 34 from resetting, so that the spring 1 37 remains in a stretched state, which facilitates the disassembly and assembly of the arc rod 1 without having to pull the circular plate 34 all the time.
