These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0037] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0038] See also Figures 1 to 3 An embodiment of the present application provides a jig 100 for arc-shaped splicing of display screen boxes (hereinafter referred to as "jig 100"), which is used to realize arc-shaped splicing of two adjacent boxes 201 in a display screen 200 and fix them on an external arc-shaped mounting surface 300. The display screen 200 includes a plurality of spliced ​​and connected boxes 201, and each box 201 is fixed on the external arc-shaped mounting surface 300 through a bracket 202.

[0039] The jig 100 of the present 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 boxes 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 boxes 201, so that the two brackets 202 can rotate relative to each other and adapt to 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 of the display surfaces 2011 of the two boxes 201.

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

[0042] Among them, 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, and the end of the first adapter portion 121 facing away from the second adapter portion 122 constitutes 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 extension direction of the first adapter portion 121 is perpendicular to the width direction of the arm body 11. As shown in FIG. Figure 5 As shown, in other examples, the angle between the first transition portion 121 and the second transition portion 122 may also be a right angle.

[0043] The angle between the first adapter portion 12 and the second adapter portion 122 allows the connecting end 1001 of the rotary arm 10 to form a 90° turn, so that the rotary arm 10 forms a similar elbow structure. This arrangement enables the arm body 11 to be relatively vertical to the surface of the rack 202 when the fixture 100 is docked with the rack 202.

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

[0046] In some implementations of the present application, each rotary arm 10 includes multiple sets of adapter groups, each set of adapter groups includes multiple adapters 12 connected to the arm body 11 at intervals, and the multiple sets of adapter groups are arranged at intervals along the length direction of the arm body 11. In some examples, each rotary arm 10 may include two sets of adapter groups, and the two sets of adapter groups are respectively arranged near the two ends of the length direction of the arm body 11.

[0047] The multiple adapter groups of the two rotary arms 10 are arranged in one-to-one correspondence, and the adapter members 12 in the two corresponding adapter groups are rotatably connected in a staggered arrangement through a rotating shaft 20 .

[0048] By setting up multiple sets of adapter groups and each adapter group including multiple adapter parts 12, the two swing arms 10 can be stably connected, and the stability of the relative rotation of the two swing arms 10 can be guaranteed, so as to ensure that the brackets 202 connected to the two swing arms 10 can form a stable relative rotation and adapt to the external arc-shaped mounting surface 300.

[0049] Further, in some embodiments of the present application, the arm body 11 includes a main body 111 and an extension 112 connected to one side of the main body 111, and both ends of the extension 112 extend 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.

[0050] The side of the main body 111 facing away from the extension portion 112 is connected to the end of the second adapter portion 122. The second adapter portion 122 is arranged at an angle with the main body 111, and the angle between the second adapter portion 122 and the main body 111 is an obtuse angle. The adapters 12 of the two swing arms 10 rotate relative to each other, so that the two main bodies 111 can be in a relatively expanded state or a relatively close state.

[0051] In some examples, weight-reducing holes 1111 may be arranged at intervals on the main body 111. A plurality of weight-reducing holes 1111 may be provided, and the shape of the weight-reducing holes 1111 may be rectangular, long, circular, etc. A plurality of weight-reducing holes 1111 may be arranged at intervals on the main body 111 to effectively reduce the overall weight of the jib 10 and facilitate use by operators.

[0052] Furthermore, the fixed end 1002 of each swing arm 10 is rotatably provided with a fastener 13. A fastening hole 2021 is provided at a corresponding position of the bracket 202, and the fastener 13 is passed through and fixed in the fastening hole 2021, so that the swing arm 10 and the bracket 202 are detachably connected.

[0053] In some examples, fasteners 13 are provided at both ends of the extension portion 112 in the length direction of each swing arm 10. Each swing arm 10 can be detachably connected to the bracket 202 through the fasteners 13 at both ends of the extension portion 112 to ensure the structural stability of the connection between the swing arm 10 and the bracket 202.

[0054] The fastener 13 may include a fastening body 131 and a hand-held portion 132 connected to the fastening body 131, and the fastening body 131 is rotatably arranged in the extension portion 112 of the swing arm 10. One end of the fastening body 131 away from the hand-held portion 132 extends outward from a side of the extension portion 112 away from the main body 111. The outer wall of the fastening body 131 is provided with an external thread, and the fastening hole 2021 is a screw hole that is threadedly adapted to the fastening body 131.

[0055] The hand-held portion 132 is used for holding by a human hand to realize the rotation of the fastener 13 relative to the swing arm 10. By rotating the hand-held portion 132 by a human hand, the fastener 13 can be locked on the bracket 202, and the fastener 13 and the bracket 202 can be disassembled. No external operating tools are required. The operator can quickly disassemble and assemble the fixture 100 and the bracket 202, which is beneficial to improving the installation efficiency of the display screen 200.

[0056] In some examples, a positioning column 14 is disposed at the fixed end 1002 of each rotary arm 10 , and a positioning hole 2023 for the positioning column 14 to pass through is disposed at a corresponding position of the hanger 202 .

[0057] The positioning column 14 is protrudingly arranged on the side of the extension portion 112 away from the main body 111, and the positioning column 14 is arranged near both ends of the extension portion 112 in the length direction. The fastener 13 can be arranged near the end of the extension portion 112, and the positioning column 14 is arranged inside the fastener 13.

[0058] The end of the positioning column 14 can be set to be tapered, and accordingly, the positioning hole 2023 on the bracket 202 can also be set to be tapered. The positioning column 14 penetrates the positioning hole 2023, so that the swing arm 10 can be positioned on the bracket 202, and the fastener 13 is locked in the fastening hole 2021, so that the swing arm 10 can be effectively positioned and fixed on the bracket 202.

[0059] like Figure 3 and Figure 7 As shown, when the fixture 100 is used to splice two adjacent boxes 201 in the display screen 200, the two rotating arms 10 can be respectively positioned and connected with the brackets 202 used to fix the boxes 201 through the fasteners 13 and the positioning columns 14. The two brackets 202 connected to the rotating arms 10 can rotate relative to each other, so as to adapt to the external arc-shaped mounting surface 300.

[0060] When the two hangers 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 joint of the display surfaces 2011 of the two boxes 201 to be installed. That is, when the boxes 201 are installed on the two hangers 202 respectively, the joint of the display surfaces 2011 of the two boxes 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 boxes 201 on the external arc-shaped mounting surface 300.

[0061] In addition, an embodiment of the present application further provides a display screen 200 , which includes a plurality of boxes 201 that are spliced ​​and connected.

[0062] like Figure 3 and Figure 7 As shown, in this embodiment, the display screen 200 further includes a plurality of hangers 202, and each box 201 is fixed to the external arc-shaped mounting surface 300 via a hanger 202. The two hangers 202 for fixing the boxes 201 to be spliced ​​in the display screen 200 are connected via the above-mentioned fixture 100 and adapted to the external arc-shaped mounting surface 300. The specific structure of the fixture 100 has been described above and will not be repeated here.

[0063] The bracket 202 is a square frame structure, which is compatible with the square box 201. The top and bottom of the bracket 202 are provided with assembly holes 2022 for fixing with the external arc-shaped mounting surface 300. Both sides of the bracket 202 are provided with fastening holes 2021 connected with the fasteners 13 of the fixture 100 and positioning holes 2023 for positioning and fixing with the positioning columns 14.

[0064] The two swing arms 10 of the fixture 100 can be positioned and connected to the two brackets 202 respectively through the fasteners 13 and the positioning columns 14, and the two brackets 202 connected to the swing arms 10 can rotate relative to each other, so as to adapt 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 joint of the display surfaces 2011 of the two boxes 201 to be installed. That is, when the boxes 201 are respectively installed on the two brackets 202, the joint of the display surfaces 2011 of the two boxes 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 boxes 201 on the external arc-shaped mounting surface 300.

[0065] For the display screen 200 of the present application, when two adjacent boxes 201 are spliced ​​on the external curved mounting surface 300, the position adjustment of the two brackets 202 on the external curved mounting surface 300 is achieved through the relative rotation of the two swing arms 10 in the jig 100, so that the brackets 202 can adapt to the installation of curved surfaces of various radians, and the axis of the rotating shaft 20 of the jig 100 on the two brackets 202 after the position adjustment can correspond to the splicing point of the display surface 2011 of the two boxes 201 to be spliced, that is, by fixing the boxes 201 on the two brackets 202 respectively, the splicing connection of the two boxes 201 on the external curved mounting surface 300 can be achieved.

[0066] Furthermore, if Figure 8 As shown, an embodiment of the present application also provides a method for installing a display screen 200, which is used to realize the splicing installation of multiple spliced ​​boxes 201 of the display screen 200 on the external arc-shaped installation surface 300. The installation method includes the following steps:

[0067] Step S10, providing a fixture 100 and a plurality of hangers 202 for fixing a box 201, wherein the two rotary arms 10 of the fixture 100 are respectively a first rotary arm 101 and a second rotary arm 102;

[0069] Step S30, another rack 202 is detachably connected to the connection end 1001 of the second rotary arm 102, and the rack 202 connected to the second rotary arm 102 is a second rack 202b;

[0070] Step S40, adjusting the position of the second bracket 202b relative to the first bracket 202a by rotating the second swing arm 102 relative to the first swing arm 101, so that the first bracket 202a and the second bracket 202b are adapted to the curvature of the external arc-shaped mounting surface 300;

[0071] Step S50, fix the second bracket 202b on the external arc-shaped mounting surface 300, then remove the fixture 100 connected to the first bracket 202a and the second bracket 202b, and install the box 201 on the first bracket 202a and the second bracket 202b respectively, so as to realize the splicing of two adjacent boxes 201 on the external arc-shaped mounting surface 300.

[0072] In step S10, Figure 1 and Figure 7 As shown, a fixture 100 is provided, and the structure of the fixture 100 has been described above and will not be repeated here.

[0073] The hanger 202 is a square frame structure, which is compatible with the square box 201. The top and bottom of the hanger 202 are provided with assembly holes 2022 for fixing with the external arc-shaped mounting surface 300. Both sides of the hanger 202 are provided with fastening holes 2021 connected with the fasteners 13 of the fixture 100 and positioning holes 2023 for positioning and fixing with the positioning columns 14.

[0074] For step S20, Fig. 9 As shown, the first bracket 202a is first fixed to the outer arc-shaped mounting surface 300 by passing the assembly part 400 through the assembly hole 2022 of the first bracket 202a, and the assembly part 400 can be an expansion screw. Then the fixture 100 is connected to the first bracket 202a, specifically, the first rotary arm 101 in the fixture 100 is connected to the first bracket 202a.

[0075] Among them, the positioning column 14 of the first swing arm 101 is passed through the positioning hole 2023 on the side of the first bracket 202a, and the fastener 13 on the first swing arm 101 is passed through the fastening hole 2021 on the side of the first bracket 202a. The fastener 13 is locked by rotating the hand-held part 132, thereby realizing the positioning and fixation of the first swing arm 101 and the first bracket 202a.

[0076] In step S30, the second swing arm 102 in the fixture 100 is connected to the second bracket 202b. Specifically, the positioning column 14 of the second swing arm 102 is inserted into the positioning hole 2023 on the side of the second bracket 202b, and the fastener 13 on the second swing arm 102 is inserted into the fastening hole 2021 on the side of the second bracket 202b. The fastener 13 is locked by rotating the handheld part 132, thereby achieving the positioning and fixing of the second swing arm 102 and the second bracket 202b.

[0077] like Fig.10 As shown, after the fixture 100 is fixed to the first bracket 202a and the second bracket 202b, step S40 is performed to adjust the position of the second bracket 202b relative to the first bracket 202a by rotating the second swing arm 102 relative to the first swing arm 101, so that the second bracket 202b rests on the external curved mounting surface 300, thereby making the first bracket 202a and the second bracket 202b adapt to the curvature of the external curved mounting surface 300.

[0078] In step S50, Fig.11 As shown, the second bracket 202b is fixed on the outer arc-shaped installation surface 300 by passing the assembly part 400 through the assembly hole 2022 of the second bracket 202b. The assembly part 400 can be an expansion screw.

[0079] The fixture 100 is connected to two hangers 202, and the two hangers 202 are fixed on the outer arc-shaped mounting surface 300.
