[0020] Compared with the prior art, the technical solution provided by the present application has the following unique beneficial effects: the present solution can directly splice the LED display screen modules one by one downwardly on the suspension beam. Since the bottom of the suspension beam is provided with a connection structure identical to the display screen mounting frame, the use of the same connection structure as the display screen mounting frame can save the design cost and production cost of the suspension beam, and the overall connection operation is consistent, thus avoiding errors, and ultimately achieving efficient, fast and safe installation and removal of large LED screens.

[0021] 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 left and right positions or up and down positions. There is no need to classify during installation, removal and transportation, and there will be no misoperation caused by incorrect distinction.

[0022] Secondly, the display screen box frame of each unit module is divided into a first installation side and a second installation side, which cooperate with each other. When correctly divided into the connection surface facing the LED display screen, the first installation side of each unit module faces the second installation side of the adjacent unit module, and the second installation side of each unit module also faces the first 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 repeated operations by operators can be guaranteed, and consistent operations can also reduce the probability of misoperation;

[0023] Secondly, the display screen box 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.

[0024] Secondly, the display screen installation frames of adjacent unit modules are connected through the arc lock assembly and the U-lock assembly. The U-lock assembly and the arc lock assembly cooperate to ensure the connection strength, stability and installation / removal efficiency of the overall installation system of the LED display screen. The arc lock assembly adjusts the splicing angle between the adjacent LED display screen box frames, thereby realizing the splicing arc of the large LED display screen;

[0025] Secondly, the windproof frame is set to a stowed state and an unfolded state. In the stowed state, it overlaps with the original display screen cabinet in height, does not occupy too much space, and does not change the basic equipment for transportation, storage, and installation of the existing display screen cabinet; in the unfolded state, the windproof frame forms a three-dimensional support mechanism, adds at least one layer of installation support structure to the original flat display screen and display screen installation frame system, and expands the surface support into a three-dimensional support, which greatly enhances the wind resistance and deformation resistance of the large LED display screen; the design concept of the windproof frame is consistent with that of the display screen installation frame, and both are the same unit modules, so there is no need to distinguish between left and right or left and right positions, and no classification is required during installation, removal and transportation, and there will be no misoperation caused by incorrect distinction; the setting of the windproof frame moves the center of gravity of the display screen support system as a whole to the main suspension frame, making the overall counterweight more balanced and reasonable; when the windproof frame is unfolded, a stable ladder structure is formed for staff to climb up and down, providing more operating space when needed.

[0043] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of this application.

[0044] Embodiment 1

[0045] The present invention relates to an assembly and splicing device for a large LED display system. A large LED display usually uses a plurality of small modular LED display modules (small LED display). A large LED display needs to be quickly assembled and disassembled in many scenarios. For example, a concert held in a stadium is rented by time. During the stage construction process, the installation time and dismantling time of the large LED display are included in the rental time. How to quickly complete the installation or disassembly within a limited time while ensuring the installation accuracy and stability of the large LED display is extremely difficult to achieve, and a relatively conservative and stable installation or disassembly process means that more venue time and higher costs are required to be rented.

[0046] In order to improve the installation or disassembly rate of large-scale LED display screens, the existing solution is to fix the small LED display modules of the large-scale LED display screen equipment on the display screen mounting frame 100 in advance, and realize the rapid splicing of 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, it not only causes great work pressure on the operators, but also easily causes installation errors and high-altitude operation risks due to the difficulty of operation and the large workload.

[0047] In order to solve the above problems, the present embodiment provides a left and right connecting device of an LED display screen box frame, including a display screen mounting frame 100, and each display screen mounting frame 100 can be mounted with an LED display screen, such as Figure 1-4 As shown, the display screen mounting frame 100 includes a first mounting side (F1 direction) and a second mounting side (F2 direction), the first mounting side of the display screen mounting frame 100 is provided with at least one arc lock assembly 10, and the second mounting side of the display screen mounting frame 100 is provided with at least one U-shaped lock assembly 20, and adjacent display screen mounting frames 100 are connected by the arc lock assembly 10 and the U-shaped lock assembly 20.

[0048] By means of the left and right connecting devices of the LED display box frame of the present embodiment, the display box frame for installing the LED display module is designed as completely identical unit modules, so that there is no need to distinguish the left and right positions, and no classification is required during installation, removal and transportation, and there will be no erroneous operation caused by incorrect distinction; the display box frame of each unit module is divided into a first installation side and a second installation side, and the first installation side and the second installation side cooperate with each other. When correctly distinguished as the connection surface facing the LED display screen, the first installation side of each unit module faces the second installation side of the adjacent unit module, and the second installation side of each unit module also faces another adjacent unit module On the first installation side of the meta-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 repeated operations by operators can be guaranteed, and consistent operations can also reduce the probability of misoperation; the display screen mounting frames 100 of adjacent unit modules are connected by the arc lock assembly 10 and the U-lock assembly 20. The U-lock assembly 20 cooperates with the arc lock assembly 10 to ensure the connection strength, stability and installation / removal operation efficiency of the overall installation system of the LED display screen. The arc lock assembly 10 adjusts the splicing angle between the adjacent LED display screen box frames, thereby realizing the splicing arc of the large LED display screen.

[0049] Specifically, the arc lock assembly 10 includes a first docking plate 101, and the U-shaped lock assembly 20 includes a second docking plate 201 that cooperates with the first docking plate 101. The arc lock can adjust the angle of the first docking plate 101 relative to the display screen mounting frame 100. When the adjacent display screen mounting frames 100 are locked and connected, the first docking plate 101 and the second docking plate 201 fit tightly together.

[0050] Adjacent display screen mounting frames 100 are connected by arc lock assemblies 10 and U-shaped lock assemblies 20. Therefore, it is necessary to design new arc lock assemblies 10 and U-shaped lock assemblies 20 to simplify the disassembly and assembly process between the display screen mounting frames 100, while also increasing the connection strength between the display screen mounting frames 100 and realizing the angle connection between the display screen mounting frames 100. In addition, the splicing of arc-shaped LED display screens is realized through the angle connection between the display screen mounting frames 100. This solution is extremely difficult to implement.

[0051] In order to achieve a quick connection between the arc lock assembly 10 and the U-shaped lock assembly 20, the present embodiment designs a U-shaped lock assembly 20 including a lock body 202, a U-shaped connecting rod 203, a handle 204, and a safety buckle 205. At the same time, the arc lock assembly 10 includes a locking groove 103 that cooperates with the U-shaped connecting rod 203, and the connection and disassembly between adjacent display screen mounting frames 100 are realized as a simple operation of buckling the U-shaped connecting rod 203 into the locking groove 103 and taking it out from the locking groove 103. At the same time, when the arc lock adjusts the angle of the first docking plate 101 to adjust the connection angle of the adjacent display screen mounting frames 100, it does not affect the operation of buckling the U-shaped connecting rod 203 into and taking out the locking groove 103 at all.

[0052] Specifically, the second docking plate 201 can be connected to the lock body of the U-shaped lock assembly 20 , or the second docking plate 201 can be fixedly disposed on the display screen mounting frame 100 .

[0053] Specifically, the lock body 202 is connected to the display screen mounting frame 100 through the first rotating shaft 207, and the U-shaped connecting rod 203 is connected to the lock body 202 through the second rotating shaft 208. When the adjacent display screen mounting frames 100 are pre-spliced, the safety buckle 205 is opened, and the U-shaped connecting rod 203 of the U-shaped lock assembly 20 is rotated along the first rotation direction so that the U-shaped end is confined in the locking groove 103 of the arc lock assembly 10. The second rotating shaft 208 is driven by the handle 204 to rotate the U-shaped connecting rod 203 along the second rotation direction so that the second connecting shaft end is reversed and enters the locking 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.

[0054] In order to achieve the connection strength between the display screen installation frames 100, the arc lock assembly 10 and the U-shaped lock assembly 20 are butt-connected, and the first butt-joint plate 101 and the second butt-joint plate 201 are matched to achieve the stable connection between the brackets of the adjacent display screen installation frames 100. The arc lock assembly 10 includes a first butt-joint plate 101, and the U-shaped lock assembly 20 includes a second butt-joint plate 201 matched with the first butt-joint plate 101. The arc lock can adjust the angle of the first butt-joint plate 101 relative to the display screen installation frame 100. When the adjacent display screen installation frames 100 are locked and connected, the first butt-joint plate 101 and the second butt-joint plate 201 are tightly fitted.

[0055] In addition, at least one positioning pin is provided on the first docking plate 101, and positioning grooves matching the position and number of the positioning pins are provided on the second docking plate 201. When the adjacent display screen installation frames 100 are pre-joined, the positioning pins are inserted into the positioning grooves to limit the relative displacement between the first docking plate 101 and the second docking plate 201. The matching structure of the positioning pins and the positioning grooves facilitates the correct joining of adjacent display screen installation frames 100 when the adjacent display screen installation frames 100 are pre-joined.

[0056] In order to achieve an angle connection between the display screen mounting frames 100, this embodiment connects the first docking plate 101 to the arc lock, and sets the second docking plate 201 in the U-shaped lock assembly 20 set on the second mounting side of the display screen mounting frame 100. A surface of the display screen mounting frame 100 facing the LED display screen is defined as the connecting surface, and the second docking plate 201 of the U-shaped lock assembly 20 is perpendicular to the connecting surface. When the arc lock assembly 10 is adjusted to 0 degrees, the first docking plate 101 is perpendicular to the connecting surface.

[0057] Specifically, the arc lock assembly 10 includes a locking buckle 102. When the locking buckle 102 is opened, the adjustment angle of the arc lock assembly 10 includes: -7.5°, -5°, -2.5°, 0°, 2.5°, -5°, -7.5°. The angle range between the first docking plate 101 and the connecting surface is adjusted by the arc lock to include: -7.5°, -5°, -2.5°, 0°, 2.5°, -5°, -7.5°, so as to achieve the angle range of adjacent display modules of the large LED display screen within the range of

[0058] : -7.5°, -5°, -2.5°, 0°, 2.5°, -5°, -7.5°. That is, the arc-shaped LED display screen is realized as the arc adjustment of the arc lock assembly 10 after preliminary calculation, and the arc is precisely adjusted by positioning the arc scale on the arc lock and the arc adjustment teeth of the arc lock. Finally, during the rapid installation process of the display screen installation frame 100, the operator can quickly realize the splicing of the arc-shaped LED display screen by adjusting the arc lock at the required position.

[0059] Specifically, the overall area of ​​the display screen installation frame 100 is slightly smaller than the area of ​​the LED display screen, that is, after the adjacent display screen installation frames 100 are connected, there are gaps between the display screen installation frames 100, but the front LED display screens are tightly spliced.

[0060] In order to achieve fast, accurate and convenient connection of adjacent display screen mounting frames 100, at least one positioning pin is provided on the first mounting side of the display screen mounting frame 100, and the second mounting side of the display screen mounting frame 100 is also provided with positioning grooves matching the number, position and structure of the positioning pins.

[0061] Embodiment 2

[0062] like Figure 5-7As shown, a device for connecting the upper and lower frames of an LED display screen box includes a display screen mounting frame 100, and an LED display screen can be mounted on each display screen mounting frame 100. 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 by the buckling portion 30 and the U-shaped lock assembly 40.

[0063] The buckling portion 30 includes a buckling plate 301, which is integrally formed with the display screen mounting frame 100, or is disposed on the display screen mounting frame 100. When adjacent display screen mounting frames 100 are locked and connected, the U-shaped lock assembly 40 is fixedly connected to the buckling plate 301. The buckling plate 301 includes a buckling groove 302 adapted to the U-shaped lock assembly 40.

[0064] The lock body 401 is connected to the display screen installation frame 100 through a first rotating shaft, and the U-shaped connecting rod 402 is connected to the lock body 401 through a second rotating shaft. When the adjacent display screen installation frames 100 are pre-spliced, the safety buckle 404 is opened, and the U-shaped connecting rod 402 of the U-shaped lock assembly 40 is rotated along the 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 drives the U-shaped connecting rod 402 to rotate along the second rotation direction through the handle 403 so that the second connecting shaft end is reversed and enters the locking position, thereby forming a locked connection state of the adjacent display screen installation frames 100, wherein the second rotation direction is opposite to the first rotation direction.

[0065] The overall area of ​​the display screen mounting frame 100 is slightly smaller than the area of ​​the LED display screen.

[0066] First, 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, and no need to classify during installation, removal and transportation, and there will be no misoperation caused by incorrect distinction;

[0067] Secondly, the display screen box 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 repeated operations by operators can be guaranteed, and consistent operations can also reduce the probability of misoperation;

[0068] Secondly, the LED display box frames of adjacent unit modules are connected through the buckling part 30 and the U-lock assembly 40. The U-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.

[0069] Embodiment 3

[0070] like Figure 8-9 As shown, this embodiment provides a windproof frame for an LED display box:

[0071] The LED display screen box windproof frame is arranged on the back of the display screen installation frame 100;

[0072] The LED display box windproof frame includes a main suspension frame in the same plane and an auxiliary bracket arranged on one side of the main suspension frame. The auxiliary bracket can be accommodated in the plane of the main suspension frame, or unfolded from the main suspension frame and fixed in an unfolded posture to form a three-dimensional support mechanism.

[0073] Furthermore, the display screen installation frame 100 includes a mounting surface and a back surface, and the mounting surface of the display screen installation frame 100 is detachably connected to the LED display screen.

[0074] Furthermore, the main suspension frame includes two longitudinally arranged fixing rods and a cross bar assembly arranged between the two fixing rods.

[0075] Furthermore, the cross bar assembly includes an upper assembly 53 and a lower assembly 54, the upper assembly 53 includes at least one latch block 55, the lower assembly 54 includes at least one latch groove, the latch block 55 of the LED display box windproof frame can be adapted and fixedly connected with the latch groove of the upper adjacent LED display box windproof frame, and the latch groove of the LED display box windproof frame can be adapted and fixedly connected with the latch block 55 groove of the lower adjacent LED display box windproof frame.

[0076] Furthermore, the upper component 53 includes two latch blocks 55, and the lower component 54 includes two latch slots. The two latch blocks 55 are respectively arranged concentrically with the two fixing rods, and the two latch slots are respectively arranged concentrically with the two fixing rods.

[0077] Furthermore, the latch block 55 is provided with a latch hole for locking in the same direction as the crossbar assembly.

[0078] Furthermore, a switch assembly is provided on the lower assembly 54, and the switch assembly is used to lock or release the latch block 55 inserted into the latch slot.

[0079] Furthermore, multiple LED display screen box windproof frames are connected through the cooperation of the upper component 53 and the lower component 54 to form a continuous display screen perpendicular to the bottom surface, and the latch block 55 of the uppermost LED display screen box windproof frame of the continuous display screen is connected to the suspension beam.

[0080] Further, the auxiliary bracket includes a support rod 61, the support rod 61 is rotatably connected to one of the fixed rods through two connecting arms 62, and a sliding arm assembly is also provided between the support rod 61 and the other fixed rod, and the sliding arm assembly includes a fixed end, a sliding arm rod 63 and a sliding sleeve;

[0081] When the auxiliary bracket is accommodated in the plane of the main suspension frame, the sliding sleeve slides upward along the support rod 61 and drives the sliding arm rod 63 from the vertical direction to the parallel direction to be accommodated to the side of the other fixed rod. When the auxiliary bracket is unfolded from the main suspension frame, the sliding sleeve slides downward along the support rod 61 and drives the sliding arm rod 63 to unfold from the parallel direction to the vertical direction to the side away from the main suspension frame. When the auxiliary bracket is fixed in the unfolded posture, the sliding sleeve moves down to the limited fixing part and makes the sliding arm rod 63 and the two connecting arms 62 in the same direction to form a support ladder allowing the user to crawl. At this time, the support rod 61 and the two fixed rods of the main suspension frame form a three-dimensional support mechanism arranged in a triangle.

[0082] Furthermore, a knob sleeve 641 is disposed at the upper end of the support rod 61 , and a screw rod 642 that cooperates with the knob sleeve 641 of the adjacent support rod 61 is disposed at the lower end of the support rod 61 .

[0087] Secondly, the setting of the windproof frame moves the center of gravity of the display support system back to the main suspension frame, making the overall weight more balanced and reasonable;

[0088] Secondly, when the windbreak is unfolded, it forms a stable ladder structure for workers to climb up and down, providing more operating space when needed.

[0089] Embodiment 5

[0090] This embodiment provides an LED display screen carrier, specifically, a trolley that carries an LED display screen, a display screen mounting frame, and a display screen box windproof frame 500. The existing large-scale LED display screen assembly process uses a large number of display screen mounting frames or a large number of box windproof frames 500. These modular display screen mounting frames or box windproof frames 500 need to occupy a large amount of site space during storage, transportation, and on-site storage. In particular, there are very high requirements for installation time at the installation site, and a large number of equipment need to be installed quickly without installation errors. The existing display screen mounting frames or box windproof frames 500 are shelf structures as a whole, which are not easy to stack and are prone to cross-interference with each other. Therefore, how to achieve the rapid storage, transportation, and installation of the display screen mounting frames or box windproof frames 500 is very difficult in practice.

[0091] In order to solve the above technical problems, this embodiment provides an LED display screen carrier, such as Fig.10 As shown, including:

[0092] A carrier body 70, wherein a plurality of first positioning structures are arranged on the carrying surface of the carrier body 70, wherein the first positioning structures are matched with the second positioning structures of the modular carrying object, and the first positioning structures and the second positioning structures are respectively arranged on two opposite sides of the modular carrying object, and adjacent modular carrying objects are spliced ​​with each other through the first positioning structures and the second positioning structures.

[0093] First, a first positioning structure is provided on the carrier body 70, and the first positioning structure cooperates with the second positioning structure of the modular carrying object to realize rapid positioning of the modular carrying object on the carrier body 70;

[0094] Secondly, the first positioning structure on the carrier body 70 is consistent with the positioning structure between the modular carrying objects, that is, the modular carrying objects themselves have mutually coordinated positioning structures, and the carrier body 70 also uses the same positioning structure. The carrier body 70 is equivalent to a modular carrying object, but only retains its first positioning structure.

[0095] By setting the above-mentioned first positioning structure, the modular carrier object can be directly fixed on the carrier body 70 without designing other positioning structures. Since the first positioning structure extends the positioning structure of the modular carrier object, the assembly or disassembly process of the modular carrier object is the same as the operation of loading it on the carrier body 70, which can also improve the overall assembly efficiency of the display screen and reduce operational errors.
