Technical Field

[0001] This invention relates to the field of display device technology, and in particular to a fixture for arc splicing of display cabinets, a display screen, and a method for installing the display screen. Background Technology

[0002] LED grandstand screens are LED screens installed in stadium grandstands, mainly used for information display, advertising, and special effects video playback within the stadium. They feature high brightness and high definition, wide viewing angle, vibrant and rich colors, fast response, and high reliability, playing a significant role in on-site information display and atmosphere creation. In recent years, the application of LED grandstand screens in various sports venues has become increasingly widespread.

[0003] As users increasingly demand higher display quality, some scenarios require enhanced immersive experiences, necessitating curved display screens. Currently, the curved areas of grandstand screens are joined using custom-made connecting pieces. Since the curvature varies for each scenario, the connecting pieces differ, leading to significant customization needs and high costs. Therefore, finding a solution to achieve curved splicing of display cabinets by customizing connecting pieces according to the curvature presents a challenging problem for those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problem in the prior art that the splicing area of ​​the arc-shaped area in the grandstand screen is made up of a custom connecting piece. The connecting piece is different for each scene with different curvature, which leads to a large demand for customization of the connecting piece and high cost.

[0005] To solve the above-mentioned technical problems, the present invention provides a fixture for arc-shaped splicing of display cabinets, used to realize the arc-shaped splicing of two adjacent cabinets in the display screen and fix them on an external arc-shaped mounting surface. The display screen includes multiple spliced ​​cabinets, each of which is fixed to the external arc-shaped mounting surface by a bracket. The fixture for arc-shaped splicing of display cabinets includes a pair of relatively rotating arms and a rotating shaft connecting the two rotating arms. Each rotating arm includes a connecting end and a fixed end. The connecting ends of the two rotating arms are rotatably connected by the rotating shaft, and the fixed ends of the two rotating arms are respectively used for detachable connection with the two brackets to be spliced.

[0006] The fixture for splicing the arc-shaped display cabinets is used when splicing two adjacent cabinets in the display screen. The fixed ends of the two rotating arms are respectively connected to the brackets used to fix the cabinets, so that the two brackets can rotate relative to each other and adapt to the external arc-shaped mounting surface. When the two brackets are connected to the external arc-shaped mounting surface, the axis of the rotating shaft corresponds to the splicing point of the display surfaces of the two cabinets.

[0007] In some embodiments of this application, the rotating arm includes an arm body and an adapter connected to the arm body, and the end of the arm body opposite to the adapter constitutes the fixed end;

[0008] The adapter includes a first adapter part and a second adapter part connected to each other. The end of the second adapter part opposite to the first adapter part is connected and fixed to the arm body. The end of the first adapter part opposite to the second adapter part constitutes the connecting end.

[0009] The first adapter and the second adapter are arranged at an angle, and the angle between the first adapter and the second adapter is an obtuse angle or a right angle.

[0010] In some embodiments of this application, the extension direction of the first adapter is perpendicular to the width direction of the arm body.

[0011] In some embodiments of this application, each of the rotating arms includes multiple sets of adapter groups, each set of adapter groups includes multiple adapter components that are spaced apart and connected to the arm body, and the multiple sets of adapter groups are arranged spaced apart along the length direction of the arm body;

[0012] The two rotating arms have multiple sets of adapters arranged in a one-to-one correspondence, and the adapters in the two corresponding sets of adapters are rotatably connected by a rotating shaft arranged in an alternating manner.

[0013] In some embodiments of this application, the second adapter portion is arranged at an angle to the arm body, and the angle between the second adapter portion and the arm body is an obtuse angle.

[0014] In some embodiments of this application, each of the rotating arms is rotatably provided with a fastener at its fixed end, and the corresponding position of the hanger is provided with a fastening hole. The fastener is inserted and fixed in the fastening hole, so that the rotating arm and the hanger are detachably connected.

[0015] In some embodiments of this application, the fastener includes a fastening body and a handheld part connected to the fastening body. The fastening body is rotatably inserted through the fixed end of the rotating arm, and the handheld part is used for a person to hold it so that the fastener can rotate relative to the rotating arm. The outer wall of the fastening body is provided with external threads, and the fastening hole is a threaded hole adapted to be screwed into the fastening body.

[0016] In some embodiments of this application, each of the rotating arms has a positioning post at its fixed end, and the corresponding position of the hanger has a positioning hole for the positioning post to pass through.

[0017] The present invention also provides a display screen, comprising multiple interconnected cabinets, and the display screen further comprising multiple brackets. Each cabinet is fixed to an external arc-shaped mounting surface by a bracket. Two brackets for fixing the cabinets to be spliced ​​in the display screen are connected by a jig for arc splicing the display screen cabinets as described above and are adapted to the external arc-shaped mounting surface.

[0018] The present invention also provides a method for installing a display screen, for splicing and installing multiple interconnected cabinets of the display screen on an external arc-shaped mounting surface, characterized in that the installation method includes the following steps:

[0019] The above-mentioned jig for arc-shaped splicing of display cabinets and several brackets for fixing the cabinets are provided; the two rotating arms of the jig for arc-shaped splicing of display cabinets are a first rotating arm and a second rotating arm, respectively.

[0020] One of the brackets is fixed on the outer arc-shaped mounting surface, and the connecting end of the first rotating arm is detachably connected to the bracket. The bracket connected to the first rotating arm is the first bracket.

[0021] Another bracket is detachably connected to the connecting end of the second rotating arm, and the bracket connected to the second rotating arm is the second bracket;

[0022] By rotating the second rotating arm relative to the first rotating arm, the position of the second bracket relative to the first bracket is adjusted, so that the first bracket and the second bracket are adapted to the curvature of the external arc-shaped mounting surface;

[0023] The second bracket is fixed to the outer arc-shaped mounting surface. Then, the jig for arc-shaped splicing of the display cabinet connected to the first bracket and the second bracket is removed. The cabinets are then installed on the first bracket and the second bracket respectively, thereby achieving the splicing of two adjacent cabinets on the outer arc-shaped mounting surface.

The connecting ends of the two rotating arms are rotatably connected through a rotating shaft. The fixed ends of the rotating arms are detachably connected to two brackets for fixing the cabinets, so that the two brackets can rotate relative to each other to adapt to the external arc mounting surface. When the two brackets connected to the jig are connected to the external arc mounting surface, the axis of the rotating shaft corresponds to the splicing point of the display surfaces of the two cabinets to be spliced, so that when the two cabinets are installed on the two brackets adjusted by the jig, splicing connection on the external arc mounting surface can be achieved. Compared with the existing method of using customized connecting pieces, this application can realize the installation of display cabinets on various arc surfaces with a single jig, which can not only effectively save assembly costs, but also simplify operation and improve assembly efficiency.

Detailed Implementation

[0035] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0036] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back, etc.) are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0038] See Figures 1 to 3 One embodiment of this application provides a jig 100 (hereinafter referred to as "jig 100") for arc splicing of display cabinets, which is used to realize the arc splicing of two adjacent cabinets 201 in the display 200 and fix them on the external arc mounting surface 300. The display 200 includes a plurality of spliced ​​cabinets 201, and each cabinet 201 is fixed on the external arc mounting surface 300 by a bracket 202.

[0039] The fixture 100 of this application includes a pair of relatively rotating arms 10 and a rotating shaft 20 connecting the two rotating arms 10. Each rotating arm 10 includes a connecting end 1001 and a fixed end 1002. The connecting ends 1001 of the two rotating arms 10 are rotatably connected through the rotating shaft 20, and the fixed ends 1002 of the two rotating arms 10 are respectively used for detachable connection with two hangers 202 to be spliced.

[0040] When the fixture 100 is used to splice two adjacent cabinets 201 in the display screen 200, the fixed ends 1002 of the two rotating arms 10 are respectively connected to the brackets 202 used to fix the cabinets 201, so that the two brackets 202 can rotate relative to each other to fit the external arc-shaped mounting surface 300. When the two brackets 202 are connected to the external arc-shaped mounting surface 300, the axis of the rotating shaft 20 corresponds to the splicing point of the display surfaces 2011 of the two cabinets 201.

[0041] In some embodiments of this application, each rotating arm 10 includes an arm body 11 and an adapter 12 connected to the arm body 11, and the end of the arm body 11 facing away from the adapter 12 constitutes a fixed end 1002.

[0042] Among them, such as Figure 4 As shown, the adapter 12 includes a first adapter portion 121 and a second adapter portion 122 connected to each other. The end of the second adapter portion 122 facing away from the first adapter portion 121 is connected and fixed to the arm body 11. The end of the first adapter portion 121 facing away from the second adapter portion 122 forms a connecting end 1001. In this example, the first adapter portion 121 and the second adapter portion 122 are arranged at an angle, and the angle between the first adapter portion 121 and the second adapter portion 122 is an obtuse angle. In this example, the extending direction of the first adapter portion 121 is perpendicular to the width direction of the arm body 11. Figure 5 As shown, in other examples, the angle between the first adapter 121 and the second adapter 122 can also be a right angle.

[0043] By setting the first adapter 12 and the second adapter 122 at an angle, the connecting end 1001 of the rotating arm 10 forms a 90° turn, thus making the rotating arm 10 form a elbow-like structure. This arrangement allows the arm body 11 to be relatively perpendicular to the surface of the bracket 202 when the fixture 100 is docked with the bracket 202.

[0044] In addition, in other examples, such as Figure 6 As shown, the adapter 12 can also be in other structural forms, such as arc-shaped or inclined plate-shaped, as long as it can make the surface of the arm body 11 and the hanger 202 relatively perpendicular when the fixture 100 is docked with the hanger 202, and make the distance L in the horizontal direction and the distance M in the vertical direction between the connection of the two rotating arms 10 and the arm body 10 a set size so that the axis of the rotating shaft 20 corresponds to the splicing point of the display surface 2011 of the two boxes 201 to be spliced.

[0045] In some embodiments of this application, each rotating arm 10 includes multiple sets of adapter groups, and each set of adapter groups includes multiple adapter pieces 12 that are spaced apart and connected to the arm body 11. The multiple sets of adapter groups are arranged at intervals along the length direction of the arm body 11. In some examples, each rotating arm 10 may include two sets of adapter groups, which are respectively located near both ends of the arm body 11 along its length direction.

[0046] The two rotating arms 10 have multiple sets of adapters arranged in a one-to-one correspondence, and the adapters 12 in the corresponding two sets of adapters are rotatably connected by a rotating shaft 20 in an alternating arrangement.

[0047] By setting multiple sets of adapter groups, each of which includes multiple adapter pieces 12, the two rotating arms 10 can be stably connected and the relative rotation stability of the two rotating arms 10 can be guaranteed, so as to ensure that the hangers 202 connected to the two rotating arms 10 form a stable relative rotation and adapt to the external arc-shaped mounting surface 300.

[0048] Furthermore, in some embodiments of this application, the arm body 11 includes a main body 111 and an extension 112 connected to one side of the main body 111, with both ends of the extension 112 extending outward from both ends of the main body 111. The main body 111 and the extension 112 can be connected by screws or integrally formed.

[0049] The side of the main body 111 facing away from the extension 112 is connected to the end of the second adapter 122. The second adapter 122 is arranged at an angle to the main body 111, and the angle between the second adapter 122 and the main body 111 is an obtuse angle. The adapters 12 of the two rotating arms 10 rotate relative to each other, so that the two main bodies 111 can be in a relatively outwardly expanded state or a relatively close state.

[0050] In some examples, weight-reducing holes 1111 can be provided at intervals on the main body 111. Multiple weight-reducing holes 1111 can be provided, and the shape of the weight-reducing holes 1111 can be rectangular, elongated, circular, etc. Multiple weight-reducing holes 1111 can be arranged at intervals on the main body 111 to effectively reduce the overall weight of the rotary arm 10 and facilitate the use by the operator.

[0051] Furthermore, each rotating arm 10 has a fastener 13 rotatably mounted on its fixed end 1002. The corresponding position of the bracket 202 is provided with a fastening hole 2021, and the fastener 13 is inserted and fixed in the fastening hole 2021, so that the rotating arm 10 and the bracket 202 are detachably connected.

[0052] In some examples, fasteners 13 are provided at both ends of the extension 112 in the length direction of each swivel arm 10. Each swivel arm 10 can be detachably connected to the bracket 202 through the fasteners 13 at both ends of the extension 112 to ensure the structural stability of the connection between the swivel arm 10 and the bracket 202.

[0053] The fastener 13 may include a fastening body 131 and a handle 132 connected to the fastening body 131. The fastening body 131 is rotatably inserted into the extension 112 of the rotating arm 10. One end of the fastening body 131 opposite to the handle 132 extends outward from the side of the extension 112 opposite to the body 111. The outer wall of the fastening body 131 is provided with external threads, and the fastening hole 2021 is a threaded hole adapted to be screwed into the fastening body 131.

[0054] The handheld part 132 is used for human hand grip to achieve rotation of the fastener 13 relative to the rotating arm 10. By rotating the handheld part 132, the fastener 13 can be locked on the bracket 202, and the fastener 13 can be disassembled from the bracket 202 without the need for external operating tools. Operators can quickly disassemble and assemble the fixture 100 and the bracket 202, which helps to improve the installation efficiency of the display screen 200.

[0055] In some examples, each rotating arm 10 has a positioning post 14 at its fixed end 1002, and the corresponding position of the bracket 202 has a positioning hole 2023 for the positioning post 14 to pass through.

[0056] The positioning pin 14 protrudes from the side of the extension 112 away from the main body 111, and is provided at both ends of the extension 112 along its length. The fastener 13 can be arranged near the end of the extension 112, and the positioning pin 14 is arranged inside the fastener 13.

[0057] The end of the positioning post 14 can be tapered, and correspondingly, the positioning hole 2023 on the bracket 202 can also be tapered. By having the positioning post 14 pass through the positioning hole 2023, the swivel arm 10 can be positioned on the bracket 202. By locking the fastener 13 in the fastening hole 2021, the positioning and fixing of the swivel arm 10 on the bracket 202 can be effectively achieved.

[0058] like Figure 3 and Figure 7 As shown, when the jig 100 is used to splice two adjacent cabinets 201 in the display screen 200, the two rotating arms 10 can be positioned and connected to the brackets 202 used to fix the cabinets 201 by fasteners 13 and positioning posts 14 respectively. The two brackets 202 connected to the rotating arms 10 can rotate relative to each other, thereby adapting to the external arc-shaped mounting surface 300.

[0059] When the two brackets 202 connected to the fixture 100 are connected to the outer arc-shaped mounting surface 300, the axis of the rotating shaft 20 corresponds to the splicing point of the display surfaces 2011 of the two cabinets 201 to be installed. That is, when the cabinets 201 are installed on the two brackets 202 respectively, the splicing point of the display surfaces 2011 of the two cabinets 201 can correspond to the axis of the rotating shaft 20 of the fixture 100, so as to effectively realize the splicing and assembly of two adjacent cabinets 201 on the outer arc-shaped mounting surface 300.

[0060] In addition, one embodiment of this application also provides a display screen 200, which includes a plurality of interconnected cabinets 201.

[0061] like Figure 3 and Figure 7 As shown, in this embodiment, the display screen 200 also includes multiple brackets 202, and each cabinet 201 is fixed to the outer arc-shaped mounting surface 300 by a bracket 202. The two brackets 202 used to fix the cabinets 201 to be spliced ​​in the display screen 200 are connected by the aforementioned fixture 100 and adapted to the outer arc-shaped mounting surface 300. The specific structure of the fixture 100 has been described above and will not be repeated here.

[0062] The bracket 202 has a square frame structure, which is compatible with the square housing 201. The top and bottom of the bracket 202 are provided with mounting holes 2022 for fixing to the external arc-shaped mounting surface 300. Both sides of the bracket 202 are provided with fastening holes 2021 for connecting to the fasteners 13 of the fixture 100, and positioning holes 2023 for positioning and fixing to the positioning post 14.

[0063] The two rotating arms 10 of the fixture 100 can be positioned and connected to the two brackets 202 respectively via fasteners 13 and positioning posts 14. The two brackets 202 connected to the rotating arms 10 can rotate relative to each other, thereby adapting to the external arc-shaped mounting surface 300. When the two brackets 202 connected to the fixture 100 are connected to the external arc-shaped mounting surface 300, the axis of the rotating shaft 20 corresponds to the splicing point of the display surfaces 2011 of the two cabinets 201 to be installed. That is, when the cabinets 201 are respectively installed on the two brackets 202, the splicing point of the display surfaces 2011 of the two cabinets 201 can correspond to the axis of the rotating shaft 20 in the fixture 100, so as to effectively realize the splicing and assembly of two adjacent cabinets 201 on the external arc-shaped mounting surface 300.

[0064] For the display screen 200 of this application, when two adjacent cabinets 201 are spliced ​​on the external arc-shaped mounting surface 300, the position of the two brackets 202 on the external arc-shaped mounting surface 300 is adjusted by the relative rotation of the two rotating arms 10 in the fixture 100, so that the brackets 202 can adapt to the installation of arc surfaces of various curvatures. After the position adjustment, the axis of the rotating shaft 20 of the fixture 100 on the two brackets 202 can correspond to the splicing point of the display surface 2011 of the two cabinets 201 to be spliced. That is, by fixing the cabinets 201 on the two brackets 202 respectively, the splicing connection of the two cabinets 201 on the external arc-shaped mounting surface 300 can be realized.

[0065] Furthermore, such as Figure 8 As shown, one embodiment of this application also provides an installation method for the display screen 200, which enables the splicing and installation of multiple interconnected cabinets 201 of the display screen 200 on the external arc-shaped mounting surface 300. The installation method includes the following steps:

[0066] Step S10: Provide a jig 100 and several brackets 202 for fixing the box 201. The two rotating arms 10 of the jig 100 are the first rotating arm 101 and the second rotating arm 102, respectively.

[0067] Step S20: Fix one of the brackets 202 on the outer arc-shaped mounting surface 300, and then detachably connect the connecting end 1001 of the first rotating arm 101 to the bracket 202. The bracket 202 connected to the first rotating arm 101 is the first bracket 202a.

[0068] In step S30, another bracket 202 is detachably connected to the connecting end 1001 of the second rotating arm 102. The bracket 202 connected to the second rotating arm 102 is the second bracket 202b.

[0069] Step S40: By rotating the second rotating arm 102 relative to the first rotating arm 101, the position of the second bracket 202b relative to the first bracket 202a is adjusted, so that the first bracket 202a and the second bracket 202b are adapted to the curvature of the external arc-shaped mounting surface 300.

[0070] In step S50, the second bracket 202b is fixed on the outer arc-shaped mounting surface 300, and the fixture 100 connected to the first bracket 202a and the second bracket 202b is disassembled. The box 201 is then installed on the first bracket 202a and the second bracket 202b respectively, thereby realizing the splicing of two adjacent boxes 201 on the outer arc-shaped mounting surface 300.

[0071] In step S10, as Figure 1 and Figure 7 As shown, a jig 100 is provided. The structure of the jig 100 has been described above and will not be repeated here.

[0072] The bracket 202 has a square frame structure, which is compatible with the square housing 201. The top and bottom of the bracket 202 are provided with mounting holes 2022 for fixing to the external arc-shaped mounting surface 300. Both sides of the bracket 202 are provided with fastening holes 2021 for connecting to the fasteners 13 of the fixture 100, and positioning holes 2023 for positioning and fixing to the positioning post 14.

[0073] For step S20, as Figure 9 As shown, the first bracket 202a is first fixed to the outer arc-shaped mounting surface 300 by means of an assembly 400 passing through the mounting hole 2022 of the first bracket 202a. The assembly 400 can be an expansion screw. Then, the fixture 100 is connected to the first bracket 202a. Specifically, the first rotating arm 101 in the fixture 100 is connected to the first bracket 202a.

[0074] The positioning post 14 of the first rotating arm 101 passes through the positioning hole 2023 on the side of the first hanger 202a, and the fastener 13 on the first rotating arm 101 passes through the fastening hole 2021 on the side of the first hanger 202a. The fastener 13 is locked by rotating the hand handle 132, thereby realizing the positioning and fixing of the first rotating arm 101 and the first hanger 202a.

[0075] In step S30, the second rotating arm 102 in the fixture 100 is then connected to the second hanger 202b. Specifically, the positioning pin 14 of the second rotating arm 102 is inserted into the positioning hole 2023 on the side of the second hanger 202b, and the fastener 13 on the second rotating arm 102 is inserted into the fastening hole 2021 on the side of the second hanger 202b. The fastener 13 is locked by rotating the handle 132, thereby achieving the positioning and fixing of the second rotating arm 102 and the second hanger 202b.

[0076] like Figure 10 As shown, after the fixture 100 is fixed to the first bracket 202a and the second bracket 202b, step S40 is performed. By rotating the second rotating arm 102 relative to the first rotating arm 101, the position of the second bracket 202b relative to the first bracket 202a is adjusted so that the second bracket 202b abuts against the outer arc-shaped mounting surface 300, thereby adapting the first bracket 202a and the second bracket 202b to the curvature of the outer arc-shaped mounting surface 300.

[0077] In step S50, as Figure 11 As shown, the second bracket 202b is fixed to the outer arc-shaped mounting surface 300 by means of the fitting 400 passing through the mounting hole 2022 of the second bracket 202b. The fitting 400 can be an expansion screw.

[0078] The fixture 100 is connected to two brackets 202, and the two brackets 202 are fixed to the outer arc-shaped mounting surface 300. In this state, the axis of the rotating shaft 20 of the fixture 100 can correspond to the splicing point of the display surface 2011 of the two cabinets 201 to be spliced. That is, by fixing the cabinets 201 on the first bracket 202a and the second bracket 202b respectively, the splicing connection of the two cabinets 201 on the outer arc-shaped mounting surface 300 can be realized.

[0079] After the second bracket 202b is fixed to the outer arc-shaped mounting surface 300, as Figure 12 As shown, the fixture 100 is removed from the first bracket 202a and the second bracket 202b by rotating the fastener 13, and then the box 201 is installed at the corresponding positions of the first bracket 202a and the second bracket 202b, thereby realizing the splicing of two adjacent boxes 201 on the external arc-shaped mounting surface 300.

[0080] The fixture for arc-shaped splicing of display cabinets, the display screen, and the installation method of the display screen in this application include a pair of relatively rotating arms. The connecting ends of the two arms are rotatably connected via a pivot. The fixed ends of the arms are detachably connected to two brackets for fixing the cabinets, allowing the two brackets to rotate relative to each other and adapt to the external arc-shaped mounting surface. When the two brackets connected to the fixture are connected to the external arc-shaped mounting surface, the axis of the pivot corresponds to the splicing point of the display surfaces of the two cabinets to be spliced, so that the two cabinets can be spliced ​​on the external arc-shaped mounting surface when mounted on the two brackets adjusted by the fixture. Compared with the existing method of using custom connecting pieces, this application can realize the installation of display cabinets on various arc-shaped surfaces with a single fixture, which can not only effectively save assembly costs but also simplify operation and improve assembly efficiency.
