[0034] When designing and manufacturing the cabinet frame structure for mounting the display screen, in order to reduce weight while facilitating assembly and disassembly, such as... Figures 1-4 As shown, this utility model provides a box frame structure. The box frame structure includes a frame body 1, a reinforcing keel 3, and a connecting lock.

[0035] The frame body 1 extends along a first direction. The reinforcing keel 3 extends along the first direction and is fixedly mounted on the first side of the frame body 1. The connecting lock 4 includes a fixing member 45, an operating component 41, and a connecting component 42. The fixing member 45 is fixedly mounted on the first side of the frame body 1. The operating component 41 is rotatably mounted on the fixing member 45. The connecting component 42 is rotatably mounted on the operating component 41. The operating component 41 has a locking position and an unlocking position, and can switch between the locking and unlocking positions to connect or separate the connecting component 42 from the adjacent frame body 1.

[0036] By installing a reinforcing keel 3 on one side of the frame body 1, the strength of the frame body 1 is improved while avoiding excessive weight increase caused by directly thickening the frame body 1. Simultaneously, a connecting lock 4 is used to connect and separate adjacent frame bodies 1. During operation, simply switching the operating component 41 to the locked or unlocked position facilitates assembly and disassembly.

[0037] In some embodiments, the reinforcing keel 3 includes a crossbeam 31, a first connecting portion 32, a second connecting portion 33, and a third connecting portion 34. The crossbeam 31 extends along a first direction. The two ends of the first connecting portion 32 are respectively connected to the first end of the crossbeam 31 and the frame body 1. The second connecting portion 33 is located between the first connecting portion 32 and the third connecting portion 34. The two ends of the second connecting portion 33 are respectively connected to the crossbeam 31 and the frame body 1. The two ends of the third connecting portion 34 are respectively connected to the second end of the crossbeam 31 and the frame body 1. Through the above arrangement, a slot is formed between the first connecting portion 32 and the second connecting portion 33, and between the second connecting portion 33 and the third connecting portion 34. This ensures a stable connection with the frame body 1, thereby supporting the frame body 1 while achieving weight reduction. In this embodiment, the crossbeam 31, the first connecting portion 32, the second connecting portion 33, and the third connecting portion 34 are an integrated structure.

[0038] In some embodiments, a first reinforcing rib 321 is provided between the first connecting portion 32 and the frame body 1, and / or a second reinforcing rib 331 is provided between the second connecting portion 33 and the frame body 1. By providing the first reinforcing rib 321, the strength of the connection between the first connecting portion 32 and the frame body 1 can be improved, thereby further improving the stability of the connection between the reinforcing rib 3 and the frame body 1 and ensuring the strength of the box frame structure. Similarly, by providing the second reinforcing rib 331, the strength of the connection between the second connecting portion 33 and the frame body 1 can be improved, ensuring the strength of the box frame structure.

[0039] In some embodiments, a mounting box 2 is provided on a first side of the frame body 1 along a first direction. The mounting box 2 has a receiving groove for accommodating a portion of the operating components 41. By providing the mounting box 2, it is convenient to subsequently arrange the wiring of the LED display screen, and the mounting box 2 is used to protect the wiring of the LED display screen. By providing a receiving groove on the mounting box 2 to accommodate a portion of the operating components 41, the space occupied by the cabinet frame structure is reduced.

[0040] In some embodiments, the operating component 41 includes an operating handle 411, which is rotatably mounted on a fixing member 45, and a connecting component 42 is rotatably mounted on the operating handle 411. In this embodiment, both ends of the operating handle 411 are rotatably mounted on the fixing member 45, and the rotation axis of the connecting component 42 on the operating handle 411 is spaced apart from the rotation axis of the operating handle 411 on the fixing member 45. During the rotation of the operating handle 411, the connecting component 42 can be moved, thereby enabling connection or release with the adjacent frame body 1.

[0041] In some embodiments, the fixing member 45 has a slot, and the operating handle 411 is provided with a locking component 43. The locking component 43 includes a mounting member 431 and an unlocking button 432. The mounting member 431 is fixedly mounted on the operating handle 411, and the unlocking button 432 is rotatably mounted on the mounting member 431. The unlocking button 432 can engage with the slot to lock the operating handle 411. When the operating handle 411 is in the locked position, the unlocking button 432 engages with the slot of the fixing member 45, thereby locking the operating handle 411 and preventing it from rotating relative to the fixing member 45. This prevents accidental contact that could cause the operating handle 411 to disengage from the locked position, thus preventing the adjacent frame body 1 from separating. When operation is required, pressing the unlocking button 432 causes it to rotate relative to the mounting member 431, thereby disengaging from the slot. At this time, the operating handle 411 can be moved from the locked position to the unlocked position.

[0042] In some embodiments, the connecting assembly 42 includes a connecting rod 422 and two movable rods 421. The two movable rods 421 are arranged at intervals on both sides of the operating handle 411 and are rotatably connected to the operating handle 411. The connecting rod 422 is disposed on the two movable rods 421. Rotating the operating handle 411 can move the connecting rod 422 so that the connecting rod 422 is located in the connecting groove 21 of the adjacent frame body 1. During the process of rotating the operating handle 411 from the locked position to the unlocked position, the movable rod 421 extends and moves the connecting rod 422 to engage with the connecting groove 21. Then, rotating the operating handle 411 in the opposite direction causes the movable rod 421 to retract the connecting rod 422, thereby tightening the two adjacent frame bodies 1 through the connecting rod 422 until the operating handle 411 is rotated to the locked position, and the locking assembly 43 locks with the fixing member 45. In this way, it is convenient to connect and lock the connected frame bodies 1.

[0043] In some embodiments, the housing frame structure further includes two sets of fine-tuning components 44, which are respectively disposed at the ends of the two moving rods 421. The fine-tuning components 44 are used to adjust the position of the connecting rod 422 on the moving rod 421. By setting the fine-tuning components 44, the position of the connecting rod 422 on the moving rod 421 can be adjusted, thereby adjusting the gap between adjacent frame bodies 1 after locking. After the display body is subsequently installed, the display effect can be guaranteed.

[0044] In some embodiments, the fine-tuning component 44 includes a screw connector 441 and an elastic member 442. The elastic member 442 is sleeved on the moving rod 421, with one end abutting against a protrusion on the moving rod 421 and the other end abutting against the end of the connecting rod 422 sleeved on the moving rod 421. The screw connector 441 is screwed to the connecting rod 422 and abuts against the end of the connecting rod 422 sleeved on the moving rod 421. By adjusting the position of the screw connector 441, the position of the connecting rod 422 on the moving rod 421 can be adjusted. Specifically, when dark lines appear between the display screen bodies, it indicates that the seam between the display screen bodies is large. By simultaneously adjusting the screw connector 441, the locking distance of the connecting lock 4 can be shortened, thereby reducing the seam between adjacent display screen bodies and eliminating the dark line problem. When bright lines appear between the display screen bodies, it indicates that the gap between the display screen bodies is too small. This can be addressed by simultaneously adjusting the screw connector 441, which will cause the built-in elastic element 442 to lift the connecting rod 422, increasing the locking distance of the connecting lock 4, thereby increasing the gap between the display screen bodies and eliminating the bright line problem.

[0045] This application also provides an LED display screen, which includes a display module and multiple cabinet frame structures as described above. The multiple cabinet frame structures are assembled and connected to form a mounting frame, and the display module is mounted on the mounting frame, which can reduce weight and facilitate assembly and disassembly.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
