The splicing and disassembly of the screen are also easier, making the assembly and disassembly operations more convenient. This solves the technical problems of cumbersome assembly and disassembly operations and low efficiency of existing LED display screens.

[0039] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0040] Example 1:

[0041] Reference Figure 3 and Figure 4 This embodiment 1 provides a carbon fiber box with a retractable support, including a box body 2 and a support body 3, with the support body 3 installed on the back of the box body 2.

[0042] See Figure 4 The bracket body 3 includes a support unit 31 and a clamping unit 32. The support unit 31 is rotatably mounted on the left side of the box body 2, and the clamping unit 32 is rotatably mounted on the right side of the box body 2. The support unit 31 is provided with a longitudinal connecting pipe 311, and the clamping unit 32 is provided with a movable clamp 322 for clamping the longitudinal connecting pipe 311.

[0043] exist Figure 1 , Figure 3 , Figure 4 and Figure 5 In the diagram, solid lines and dashed lines distinguish the use state and storage state of the bracket body 3. In the use state, the clamping unit 32 and the support unit 31 clamp together and form a triangular support structure with the cabinet body 2; in the storage state, the clamping unit 32 and the support unit 31 are folded and stored on the back of the cabinet body 2, making it easy to pick up and move during the disassembly and assembly of the screen.

[0044] like Figure 3 and Figure 4 As shown, as a feasible solution, the bracket body 3 also includes a first mounting plate 33 and a second mounting plate 34. The first mounting plate 33 is installed on the left side of the box body 2 by bolts, and the support unit 31 is rotatably connected to the first mounting plate 33. The second mounting plate 34 is installed on the right side of the box body 2 by bolts, and the clamping unit 32 is rotatably connected to the second mounting plate 34.

[0045] In actual production applications, the longitudinal connecting pipe 311 is connected to the first mounting plate 33 via the first crossbar 312, and the movable clamp 322 is connected to the second mounting plate 34 via the second crossbar 321. One end of the first crossbar 312 is bolted to the longitudinal connecting pipe 311, and the other end is rotatably connected to the first mounting plate 33 via a hinge or hinge. One end of the second crossbar 321 is connected to the movable clamp 322, and the other end is rotatably connected to the second mounting plate 34 via a hinge or hinge.

[0046] See Figure 4 and Figure 5 In some feasible solutions, the movable clamp 322 includes a first clamping plate 3221, a second clamping plate 3222, a spring 3223, and a rotating shaft. The first clamping plate 3221 is fixedly connected to the second crossbar 321 by bolts and is assembled with the second clamping plate 3222 to form a C-shaped clamping groove. The rotating shaft passes through the first clamping plate 3221, the second clamping plate 3222, and the spring 3223. One end of the spring 3223 abuts against the first clamping plate 3221, and the other end abuts against the second clamping plate 3222. Therefore, the size of the clamping groove can be changed to clamp the longitudinal connecting pipe 311 in the clamping groove or remove it from the clamping groove.

[0047] See Figure 5 The second crossbar 321 is provided with a first storage structure 3201 and a second storage structure 3202. In this embodiment 1, the first storage structure 3201 includes a storage column and an elastic element. One end of the storage column is fixed inside the second crossbar 321, and the other end extends out of the second crossbar 321 and is fitted with the elastic element. The longitudinal connecting pipe 311 is provided with a storage hole at a position corresponding to the first storage structure 3201. The elastic element is inserted into and fixed in the storage column, and a protrusion is formed on the top and / or bottom surface of the storage column. The elastic element can be made of rubber or silicone, so the first storage structure 3201 can only be inserted into or withdrawn from the storage hole under the action of external force. The second storage structure 3202 is set at a position opposite to the control box 22. The second storage structure 3202 can be a magnet, and a corresponding iron sheet is installed on the control box 22.

[0048] When storing, first rotate the clamping unit 32 forward so that the second crossbar 321 is attached to the control box 22 of the box body 2. The two are fixed together by magnetic attraction, thus storing the clamping unit 32. Then rotate the support unit 31 forward so that it is close to the clamping unit 32, so that the storage hole of the longitudinal connecting tube 311 is engaged with the first storage structure 3201, so that the second crossbar 321 and the longitudinal connecting tube 311 are connected together, thus storing the support unit 31.

[0049] See Figure 4 The upper end of the longitudinal connecting pipe 311 has a straight protrusion, and the lower end has a groove that matches the protrusion, so that the longitudinal connecting pipes 311 of two adjacent box bodies 2 can be inserted and connected together.

[0050] See Figure 1 The enclosure body 2 includes an enclosure frame 21 and a control box 22. The control box 22 is installed on the back of the enclosure frame 21 and is used to connect to the LED display module 1 to provide power and signals to the LED display module 1. The control box 22 is provided with multiple connecting wires 23, which are used for signal input and output, and power input and output, respectively.

[0051] See Figure 1 and Figure 3 The upper end of the box frame 21 is provided with an upper positioning component 25, and the lower end is provided with a lower positioning component 26. The upper positioning component 25 is equipped with a positioning post, and the lower positioning component 26 is equipped with a matching positioning hole so that the two adjacent box bodies 2 can be positioned and installed.

[0052] Example 2:

[0053] Reference Figures 1 to 4This embodiment 2 provides an LED display screen, including the aforementioned carbon fiber housing with a retractable support. Several LED display modules 1 are magnetically mounted on the front of the carbon fiber housing, forming screen units. Multiple screen units are spliced ​​together to form an LED display screen. During screen assembly, support units 31 clamp together, and the longitudinal connecting tubes 311 of adjacent vertically aligned screen units are connected together. Two adjacent horizontally aligned screen units are connected together via left and right connecting locks. The left and right connecting locks can be existing matching left and right locks, which will not be elaborated upon here. The longitudinal connecting tubes 311 can be detachably connected together by insertion, snap-fit, or threaded connection.
