[0002] LCD splicing is a function that enables single-screen or multi-screen display by splitting the image. It can be spliced ​​arbitrarily according to different usage needs. LCD splicing screens are widely used in digital billboards, security monitoring, large-scale exhibitions and studios.

[0003] A circular video wall is a type of LCD video wall. A common circular video wall consists of three to six sets of curved LCD screens. Since there are relatively few applications for circular LCD screens, their splicing brackets usually need to be customized. Customized brackets not only extend the project schedule but also have relatively high costs, which to some extent limits the development of circular video walls. Therefore, a new LCD screen splicing bracket is needed to solve the above problems. Summary of the Invention

The mounting frame is fixedly connected to the plug rod.

[0009] The synchronization mechanism includes six sets of lead screws equidistantly arranged around the cylinder. Each of the six sets of lead screws is alternately arranged with one of the six sets of mounting cylinders. Each of the six sets of lead screws is fitted with a sliding block, which is slidably connected to each of the six sets of lead screws. Each of the six sets of sliding blocks is fitted with two sets of connecting rods, which are hinged to the sliding block. The ends of the connecting rods furthest from the sliding block are respectively hinged to two sets of insert rods adjacent to the sliding block. Each of the six sets of lead screws is fitted with a locking nut (b), which is threadedly connected to each of the six sets of lead screws and abuts against the corresponding sliding block.

[0014] As a preferred embodiment of the LCD splicing bracket of the present invention, the cylindrical body and the two sets of connecting rings are all made of stainless steel, and the surfaces of the cylindrical body and the two sets of connecting rings are coated with anti-corrosion coating.

[0015] In a preferred embodiment of the LCD splicing bracket of the present invention, the sliding block is provided with a sliding hole that fits with the lead screw in the radial direction, and the sliding block is slidably connected to the lead screw through the sliding hole.

[0016] Based on the above-mentioned LCD screen splicing bracket, the present invention further provides a splicing method for the LCD screen splicing bracket, including the following splicing steps:

[0017] S1. Place the mounting cylinder between the two sets of connecting rings and align it with a set of mounting holes. Insert positioning pins a and b into the aligning positioning cylinders a and b respectively. Secure the mounting cylinder with the external hexagonal screw and locking nut a. Repeat the above operation to install the six sets of mounting cylinders equidistantly between the two sets of connecting rings.

[0018] S2, screw the lead screw into the threaded cylinder located in the middle of the two adjacent sets of mounting cylinders, repeat this operation to install the six sets of lead screws. After the six sets of lead screws are installed, put the six sets of sliding blocks on the six sets of lead screws respectively. After the six sets of sliding blocks are installed, hinge each set of connecting rods to the corresponding sliding blocks and plug rods to complete the bracket assembly.

[0019] S3. Secure the six LCD screens to the six mounting frames using screws or suitable structural components. After the LCD screens are secured, push one of the LCD screens, and the corresponding mounting frame will move inward. Under the drive of the connecting rods, the six mounting frames will converge inward, and the six LCD screens will move synchronously. When the six LCD screens abut against each other, screw the six locking nuts into the six lead screws and abut against the corresponding sliding blocks. At this point, the sliding blocks are fixed in position, the positions of each LCD screen are fixed, and the splicing is complete.

At the same time, the device can be used to splice screens of different sizes, with a wide range of applications. Compared with customized splicing brackets, it helps to reduce splicing costs and shorten the project schedule. Attached Figure Description
