Description

Technical Field

[0001] The present application belongs to the technical field of display device installation devices, and more specifically, relates to an installation and positioning device. Background Art

[0002] With the development of LED display screens, the demand for various special-shaped screens has increased significantly, and the market scale is expanding day by day, among which the demand for inner arc display screens has increased most significantly. For curved display screens with different radii, the general solution on the market is to customize different connectors according to the needs of different radii or use complex arc locks to connect the display cabinets, so as to obtain curved display screens with different radii. When some existing display cabinets use connectors to install the display cabinets, it is necessary to first remove the light panel assembly of the display cabinet from the cabinet assembly, and then fix the two cabinet assemblies on the two cabinet mounting surfaces of the connectors at fixed angles, and finally reinstall the light panel assembly. In order to avoid the appearance of light and dark lines on the curved display screen after assembly, it is necessary to ensure that the adjacent two sides of the adjacent light panel assemblies overlap after reinstallation. Because the light panel assembly itself has a certain thickness, it can be concluded that when installing two adjacent cabinet assemblies, a certain gap needs to be left between the two adjacent cabinet assemblies.

[0003] However, after the light panel assembly is removed from the box assembly, the gap between the two adjacent box assemblies cannot be controlled. Bright and dark lines are likely to appear on the curved display screen after assembly. The installation position of the box assembly needs to be adjusted repeatedly to alleviate the problem of bright and dark lines, resulting in low installation efficiency and poor effect.

[0043] As described in the background art, with the development of LED displays, the demand for various special-shaped screens has increased significantly, and the market scale has been expanding day by day. Among them, the demand for inner arc displays has increased most significantly. For arc-shaped displays with different radii, the general solution in the market is to customize different connectors according to different radius requirements or use complex arc locks to connect the display boxes, so as to obtain arc-shaped displays with different radii. When some existing display boxes are installed using connectors, it is necessary to first remove the light board assembly of the display box from the box assembly, then fixedly install the two box assemblies on the two box mounting surfaces at a fixed angle of the connector respectively, and finally reinstall the light board assembly. In order to avoid bright and dark lines on the assembled arc-shaped display, it is necessary to ensure that the adjacent sides of the front surfaces of two adjacent light board assemblies coincide after reinstallation. Also, because the light board assembly itself has a certain thickness, it can be concluded that when installing two adjacent box assemblies, a certain gap needs to be left between the two adjacent box assemblies. However, after the light board assembly is removed from the box assembly, the gap between the two adjacent box assemblies cannot be controlled, and bright and dark lines are likely to appear on the assembled arc-shaped display. It is necessary to repeatedly adjust the installation position of the box assembly to alleviate the situation of bright and dark lines, resulting in low installation efficiency and poor effect.

The installation and positioning device provided in the present embodiment connects the first main body 10 and the second main body 20 to two adjacent box assemblies respectively, and sets the pivot axis of the first main body 10 and the second main body 20 to be located in the intersection area, so that when the two adjacent box assemblies are respectively installed on the two box installation surfaces of the box connecting member 60 at a fixed angle through the installation and positioning device, the installation positions of the two box assemblies can be adjusted with reference to the pivot axis of the first main body 10 and the second main body 20, so as to ensure that after the installation of the two adjacent display boxes, the gap between the side of the first display surface 43 close to the second display surface 53 and the side of the second display surface 53 close to the first display surface 43 can be controlled within a preset range, thereby avoiding the phenomenon of bright and dark lines between the two adjacent display boxes.

[0080] See Figures 8 to 12As shown, in a specific embodiment, when using the installation and positioning device provided in this embodiment to install two adjacent display boxes in the first direction, first use the connecting screws to lock the two adjacent display boxes in the first direction, and make the display surfaces of the two adjacent display boxes flush. At this time, an intersection area will be formed between the two adjacent display surfaces in the first direction. Then, the installation and positioning device provided in this embodiment is placed on the upper side of the display box, and the first main body 10 and the second main body 20 are positioned respectively by the first positioning structure and the third positioning structure. After the first main body 10 and the second main body 20 are positioned, the position of the pivot axis between the first main body 10 and the second main body 20 can be fine-adjusted to be located in the intersection area. After the position adjustment of the pivot axis between the first main body 10 and the second main body 20 is completed, the first main body 10 and the second main body 20 can be connected to the two adjacent display boxes respectively by the first connecting member and the second connecting member, thereby ensuring that the rotation axis of the two adjacent display boxes can always be maintained in the intersection area of the display surface. Then, The lamp panel assembly is removed from the box assembly, and the box connecting screws that lock the two adjacent display boxes in the first direction are loosened. At this time, the two adjacent display boxes in the first direction can be rotated at a preset angle respectively, so that the equipment mounting surfaces of the two adjacent box assemblies are respectively abutted against the two box mounting surfaces of the box connecting piece 60 at a fixed angle. Then the two adjacent box assemblies can be locked on the box connecting piece 60. At this time, the installation between the box assembly and the box connecting piece 60 is completed. After the box assembly is installed on the box connecting piece 60, the lamp panel assembly can be reinstalled on the box assembly, and the installation positioning device can be removed from the box assembly. Finally, the flat connecting piece 70 and the square tube 80 are used to fix the box connecting piece 60 on site, thereby completing the on-site fixing of the two display boxes. Repeating the above actions can complete the one-time installation of the entire curved display screen 90 without repeated disassembly and adjustment of the bright and dark lines. By using the installation positioning device provided in this embodiment, the one-time installation of the curved display screen 90 can be achieved, which improves the installation efficiency and ensures a better display effect.

[0081] In summary, the implementation of the installation and positioning device provided in this embodiment has at least the following beneficial technical effects: the installation and positioning device provided in this embodiment connects the first body 10 and the second body 20 to two adjacent box assemblies respectively, and sets the pivot axis of the first body 10 and the second body 20 to be located in the intersection area, so that when the two adjacent box assemblies are respectively installed on the two box installation surfaces of the box connector 60 at a fixed angle through the installation and positioning device, the installation positions of the two box assemblies can be adjusted with reference to the pivot axis of the first body 10 and the second body 20, so as to ensure that after the installation of the two adjacent display boxes, the gap between the side of the first display surface 43 close to the second display surface 53 and the side of the second display surface 53 close to the first display surface 43 can be controlled within a preset range, thereby avoiding the phenomenon of bright and dark lines between the two adjacent display boxes. Compared with the method of directly installing the box assembly in the prior art, the installation and positioning device provided in this embodiment is used to position and install the two adjacent box assemblies, without repeatedly adjusting the installation position of the box assembly, which not only has high installation efficiency but also has good installation effect.
