[0024] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0025] The following is combined with Figure 1-Figure 5 This embodiment is described in further detail.

[0026] like Figure 1-2 As shown, the LED display cabinet in this embodiment includes mutually spliced ​​frames 100, and the sides of the frames 100 are provided with connection holes 102 for mutual docking. The sides of the frames 100 are bent toward the inside of the frames 100 to form a mounting back plate 101, and the opposite sides of the frames 100 are provided with pre-alignment structures, and the pre-alignment structure includes a pre-alignment component 110 provided on one side and an alignment hole 103 provided on the other side and for the pre-alignment component 110 to extend into, and a reinforcement structure 120 is provided in the frame 100 and at the four corners.

[0027] In actual use of this embodiment, when the frames 100 are spliced, bolts are inserted through the corresponding connection holes 102 to splice adjacent frames 100, thereby realizing the assembly of the LED display box.

[0028] Among them, by setting the pre-alignment structure, when the adjacent frames 100 are connected by bolts, the frames 100 can be positioned during splicing, thereby ensuring that the corresponding connection holes 102 of the spliced ​​frames 100 are aligned with each other, so that the adjacent frames 100 can be spliced ​​with bolts later;

[0029] Among them, by setting the pre-alignment component 110 and the alignment hole 103, during actual installation, the pre-alignment component 110 is installed on one side of the frame 100, and the pre-alignment component 110 is extended into the alignment hole 103 on the side of the adjacent frame 100, thereby better ensuring that the corresponding connection holes 102 are aligned with each other when the frames 100 are spliced;

[0030] In this embodiment, the mounting back plate 101 is a mesh frame formed by a plurality of horizontal bars and vertical bars, which is located on one side of the frame 100. The mounting back plate 101 can be used to facilitate the installation of the existing LED display screen on the frame 100.

[0031] Among them, by setting the reinforcing structure 120, in actual use, the reinforcing structure 120 is installed on the mounting back plate 101, and the reinforcing structure 120 is used to strengthen the strength of the four corners of the frame 100 to avoid bending and deformation of the four corners of the frame 100.

[0032] Combination Figure 3-4 As shown, the pre-alignment component 110 in this embodiment includes a mounting tube 200 with openings at both ends, and an alignment rod 330 is provided in the mounting tube 200 with both ends extending out of the mounting tube 200. The alignment rod 330 is telescopically arranged in the mounting tube 200, and one end of the alignment rod 330 passes through the frame 100 and extends into the alignment hole 103 to achieve pre-alignment when the frame 100 is spliced.

[0033] In actual use of this embodiment, one end of the mounting tube 200 extends outward to form a mounting ring portion 201, and the mounting ring portion 201 can be preferably installed on the side of the frame 100 by screws penetrating the mounting ring portion 201, thereby achieving the installation of the pre-alignment assembly 110 on the side of the frame 100;

[0034] During actual use, a through hole is preset on the side of the frame 100 for the alignment rod 330 to extend out, wherein, by utilizing the arrangement of the alignment rod 330, one end of the alignment rod 330 extends out of the mounting tube 200 and passes through the through hole and is inserted into the corresponding alignment hole 103, thereby better realizing the pre-alignment when the frame 100 is spliced; wherein, since the other end of the alignment rod 330 is arranged to extend outside the mounting tube 200, the other end of the alignment rod 330 can be moved in the mounting tube 200, and the operation is simple and convenient.

[0035] In this embodiment, a fixing cylinder 310 is provided at an opening at one end of the mounting cylinder 200 for one end of the alignment rod 330 to pass through, and a blocking ring 320 is provided at an opening at the other end of the mounting cylinder 200 for the other end of the alignment rod 330 to pass through. A blocking ring 331 is provided on the alignment rod 330 between the blocking ring 320 and the fixing cylinder 310, and a spring 340 is provided on the outer sleeve of the alignment rod 330 for driving the blocking ring 331 to fit the blocking ring 320 to drive one end of the alignment rod 330 to retract. Positioning grooves are relatively provided on the side walls of the fixing cylinder 310, and a positioning slide column 332 is provided on the side walls of the alignment rod 330 for sliding in the corresponding positioning groove. The positioning slide column 332 slides into the positioning groove to keep one end of the alignment rod 330 extending out of the mounting cylinder 200.

[0036] In actual use of this embodiment, an overlap groove 202 is provided along the circumference of the opening at one end of the installation tube 200, and one end of the fixing tube 310 extends outward to form a boss 314. The fixing tube 310 is connected to the installation tube 200 by threads, and the boss 314 is overlapped in the overlap groove 202 to prevent the fixing tube 310 from extending too much into the installation tube 200. At the same time, it can ensure that the outer end of the fixing tube 310 is flush with one end of the installation tube 200, so that the installation tube 200 can be installed on the side of the frame 100.

[0037] The spring 340 and the retaining ring 331 are arranged so that the spring 340 pushes the retaining ring 331 to fit the blocking ring 320 so that one end of the alignment rod 330 can be retracted into the installation tube 200, that is, the alignment rod 330 is prevented from extending out of the frame 100 to affect the splicing between the frames 100;

[0038] In this embodiment, the positioning slide groove includes a first slide groove 311 and a second slide groove 313 axially arranged along the fixed cylinder 310, and the opposite ends of the first slide groove 311 and the second slide groove 313 are connected by a third slide groove 312, and the third slide groove 312 is circumferentially arranged along the fixed cylinder 310. Therefore, in actual use, by pressing the other end of the alignment rod 330, the positioning slide post 332 slides along the first slide groove 311 to the end connected to the third slide groove 312, so that one end of the alignment rod 330 extends out of the mounting cylinder 200. At this time, the alignment rod 330 is rotated along the third slide groove 312 to The positioning slide post 332 slides to the second slide groove 313. During this process, it is possible to better ensure that one end of the alignment rod 330 remains in an extended state, wherein the length of the second slide groove 313 is less than the length of the first slide groove 311. At the same time, in conjunction with the setting of the spring 340, the spring 340 can drive the positioning slide post 332 to slide into the second slide groove 313. At this time, it is possible to better avoid ensuring that one end of the alignment rod 330 is extended, and at the same time, the alignment rod 330 can be restricted to avoid its erroneous rotation causing one end of it to retract, so that the alignment rod 330 can be better kept in an extended state;

[0039] The blocking ring 320 is connected to the opening at the other end of the installation tube 200 by means of threads, thereby better realizing the disassembly and assembly of the alignment rod 330 and the spring 340 in the installation tube 200.

[0040] Combination Figure 5 As shown, the reinforcement structure 120 includes a triangular prism-shaped reinforcement block 400, which is concave toward the side of the frame 100 to form a cavity 403. The upper and lower sides of the reinforcement block 400 and one edge are provided with threaded holes 401, and the threaded holes 401 are provided with long rod bolts threadedly connected to the mounting back plate 101.

[0041] In actual use of this embodiment, the reinforcing block 400 is in the shape of a triangular prism, so that when it is installed at the four corners of the frame 100, its adjacent side walls can fit with the side edges of the frame 100, so that it can strengthen the structure of the frame 100 and avoid deformation at the four corners of the frame 100;

[0042] The cavity 403 is provided to reduce the weight of the reinforcing block 400, so as to realize a lightweight design of the reinforcing block 400. In order to improve the structural strength of the reinforcing block 400, a reinforcing plate 402 is provided in the cavity 403 to support the upper and lower sides of the reinforcing block 400, so as to achieve a better reinforcing effect on the frame 100.

[0043] Among them, through the setting of the threaded hole 401, a long rod bolt is used to penetrate the mounting back plate 101 and threadedly extend into the threaded hole 401, so that the reinforcement block 400 can be better disassembled and assembled on the mounting back plate 101, making the disassembly and assembly of the reinforcement structure 120 on the frame 100 more convenient.

[0044] Working principle: First, the frames 100 are brought close to each other for splicing, and then the other end of the alignment rod 330 is pressed to make the positioning slide post 332 slide along the first slide groove 311 to the third slide groove 312, so that one end of the alignment rod 330 extends out of the frame 100 and is inserted into the alignment hole 103 on the side of the adjacent frame 100. At this time, the alignment rod 330 is rotated to make the positioning slide post 332 slide along the third slide groove 312 to the second slide groove 313, and the alignment rod 330 is released. The spring 340 drives the positioning slide post 332 to slide into the second slide groove 313, thereby better ensuring that one end of the alignment rod 330 is in the corresponding alignment hole 103, and better positioning and aligning the spliced ​​frames 100, and then the adjacent frames 100 can be spliced ​​by using bolts to penetrate the corresponding connecting holes 102.
