Description

Technical Field

[0001] The invention relates to an upper and lower connection device for a LED display screen box frame, and belongs to the technical field of large-scale LED display screen assembly equipment. Background Art

[0002] Large LED display screens need to be formed by splicing and assembling multiple modular LED display modules. The LED display screen box frame of this solution is used to fix each LED display module and splice and assemble all LED display modules into a large LED display screen.

[0003] The connection structure of the existing LED display box frame usually uses conventional connection methods such as bolts, which makes the assembly of large LED displays extremely labor-intensive. Moreover, since the assembly work may also involve high-altitude operations, the huge workload also brings high risks to the assembly process. Therefore, the existing LED display box frame assembly method urgently needs to be improved. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide an upper and lower connection device for an LED display screen box frame.

[0005] According to an embodiment of the present invention, a first solution is provided: a device for connecting the upper and lower frames of an LED display screen box, comprising a display screen mounting frame, each display screen mounting frame being capable of mounting an LED display screen, the display screen mounting frame comprising a third mounting side and a fourth mounting side, the third mounting side of the display screen mounting frame being provided with at least one buckling portion, the fourth mounting side being provided with at least one U-shaped lock assembly, and adjacent display screen mounting frames being connected by means of the buckling portion and the U-shaped lock assembly.

[0006] Furthermore, the snap-fitting portion includes a snap-fitting plate, which is integrally formed with the display screen mounting frame, or is provided on the display screen mounting frame. When adjacent display screen mounting frames are locked and connected, the U-shaped lock assembly is fixedly connected to the snap-fitting plate.

[0007] Furthermore, the snap-fit plate includes a snap-fit groove adapted to the U-shaped lock assembly.

[0008] Furthermore, the U-shaped lock assembly includes a lock body, a U-shaped connecting rod, a handle, and a safety buckle, and the arc lock assembly includes a locking groove that cooperates with the U-shaped connecting rod.

[0009] Furthermore, the lock body is connected to the display screen mounting frame through a first rotating shaft, and the U-shaped connecting rod is connected to the lock body through a second rotating shaft. When the adjacent display screen mounting frames are pre-spliced, the safety buckle is opened, and the U-shaped connecting rod of the U-shaped lock assembly is rotated along the first rotation direction so that the U-shaped end is confined in the snapping groove of the snapping part. The second rotating shaft is driven by the handle to rotate the U-shaped connecting rod along the second rotation direction so that the second connecting shaft end is reversed and enters the locking position, forming a locked connection state of the adjacent display screen mounting frames, wherein the second rotation direction is opposite to the first rotation direction.

[0010] Furthermore, the overall area of the display screen installation frame is slightly smaller than the area of the LED display screen.

[0011] According to the embodiment of the present invention, using the upper and lower connection device of the LED display box frame in the first solution provided by the present invention, a second solution is provided:

[0012] An integrated LED display screen installation system includes any of the above-mentioned upper and lower connection devices of the display screen box frame.

[0013] Compared with the existing technology, the technical solution provided by this application has the following unique beneficial effects:

[0014] First, the display cabinet frame where the LED display modules are installed is designed to be identical unit modules. This way, there is no need to distinguish between upper and lower positions, and there is no need to sort them during installation, removal, and transportation, which will also prevent misoperation due to incorrect distinction.

[0015] Secondly, the display screen cabinet frame of each unit module is divided into a third installation side and a fourth installation side. The third installation side and the fourth installation side cooperate with each other. When correctly divided into the connection surface facing the LED display screen, the third installation side of each unit module faces the fourth installation side of the adjacent unit module, and the third installation side of each unit module also faces the fourth installation side of another adjacent unit module. In the overall installation system of the LED display screen, the installation and removal operations of each unit module are the same, the efficiency of the operator's repeated operations can be guaranteed, and the consistency of operation can also reduce the probability of incorrect operation;

[0016] Secondly, the LED display box frames of adjacent unit modules are connected through the buckling part and the U-shaped lock assembly. The cooperation between the U-shaped lock assembly and the buckling part ensures the connection strength, stability and installation / removal efficiency of the overall installation system of the LED display.

[0024] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0025] Example 1

[0026] This solution involves an assembly and splicing device for a large LED display system. Large LED displays typically use multiple small modular LED display modules (small LED displays). Large LED displays require rapid assembly and disassembly in many scenarios. For example, concerts held in stadiums are rented on a time-based basis. During stage construction, the installation and dismantling time of the large LED display are included in the rental period. It is extremely difficult to quickly complete the installation or disassembly within a limited timeframe while ensuring the installation accuracy and stability of the large LED display. A relatively conservative and stable installation or disassembly process requires more venue rental time and results in higher costs.

[0027] In order to improve the installation or disassembly speed of a large LED display screen, the existing solution is to fix the small LED display modules of the large LED display screen on the display screen mounting frame 100 in advance, and then quickly splice the LED display modules by splicing the display screen mounting frame 100 on site. However, the splicing operation of the existing display screen mounting frame 100 is relatively complicated, resulting in insufficient installation efficiency. Due to the limited on-site operation time, not only does it cause great work pressure on the operators, but it can also easily lead to installation errors and the risk of high-altitude operations due to the difficulty and workload of the operation.

[0028] An upper and lower connection device for the LED display box frame, such as Figure 1 As shown, it includes a display screen mounting frame 100, each of which can be mounted on an LED display screen. The display screen mounting frame 100 includes a third mounting side and a fourth mounting side. The third mounting side of the display screen mounting frame 100 is provided with at least one buckling portion 30, and the fourth mounting side is provided with at least one U-shaped lock assembly 40. Adjacent display screen mounting frames 100 are connected through the buckling portion 30 and the U-shaped lock assembly 40.

[0029] The fastening portion 30 includes a fastening plate 301, which is integrally formed with the display mounting frame 100 or provided on the display mounting frame 100. When adjacent display mounting frames 100 are locked and connected, the U-shaped lock assembly 40 is fixedly connected to the fastening plate 301. The fastening plate 301 includes a fastening groove 302 that is adapted to fit within the U-shaped lock assembly 40.

[0030] The U-shaped lock assembly includes a lock body 401, a U-shaped connecting rod, a handle 403, and a safety buckle 404. The arc lock assembly includes a locking groove that cooperates with the U-shaped connecting rod.

[0031] The lock body 401 is connected to the display screen mounting frame 100 via a first rotating shaft, and the U-shaped connecting rod 402 is connected to the lock body 401 via a second rotating shaft. When the adjacent display screen mounting frames 100 are pre-assembled, the safety buckle 404 is opened, and the U-shaped connecting rod 402 of the U-shaped lock assembly 40 is rotated along a first rotation direction so that the U-shaped end is confined in the locking groove 302 of the locking portion 30. The second rotating shaft is driven by the handle 403 to rotate the U-shaped connecting rod 402 along a second rotation direction so that the second connecting shaft end is reversed and enters the locked position, thereby forming a locked connection state of the adjacent display screen mounting frames 100, wherein the second rotation direction is opposite to the first rotation direction.

[0032] The overall area of the display screen mounting frame 100 is slightly smaller than the area of the LED display screen.

[0033] First, the display cabinet frame where the LED display modules are installed is designed to be identical unit modules. This way, there is no need to distinguish between upper and lower positions, and there is no need to sort them during installation, removal, and transportation, which will also prevent misoperation due to incorrect distinction.

[0034] Secondly, the display screen cabinet frame of each unit module is divided into a third installation side and a fourth installation side. The third installation side and the fourth installation side cooperate with each other. When correctly divided into the connection surface facing the LED display screen, the third installation side of each unit module faces the fourth installation side of the adjacent unit module, and the third installation side of each unit module also faces the fourth installation side of another adjacent unit module. In the overall installation system of the LED display screen, the installation and removal operations of each unit module are the same, the efficiency of the operator's repeated operations can be guaranteed, and the consistency of operation can also reduce the probability of incorrect operation;

[0035] Secondly, the LED display box frames of adjacent unit modules are connected through the buckling part 30 and the U-shaped lock assembly 40. The U-shaped lock assembly 40 cooperates with the buckling part 30 to ensure the connection strength, stability and installation / removal operation efficiency of the overall installation system of the LED display.

[0036] Example 2

[0037] An integrated LED display screen installation system includes any of the above-mentioned upper and lower connection devices of the display screen box frame.

[0038] The display cabinet frame where the LED display module is installed is designed to be completely identical unit modules, so there is no need to distinguish between upper and lower positions. There is no need to classify them during installation, removal and transportation, and there will be no misoperation caused by incorrect distinction.

[0039] The display screen box frame of each unit module of the LED display screen overall installation system is divided into a third installation side and a fourth installation side. The third installation side and the fourth installation side cooperate with each other. When correctly divided into connection surfaces facing the LED display screen, the third installation side of each unit module faces the fourth installation side of the adjacent unit module, and the third installation side of each unit module also faces the fourth installation side of another adjacent unit module. In the LED display screen overall installation system, the installation and removal operations of each unit module are the same, the efficiency of the operator's repeated operations can be guaranteed, and consistent operations can also reduce the probability of incorrect operations.
