Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal screen installation, in particular to a multi-mode splicing screen locking component. Background Art

[0002] Multi-screen splicing display systems are widely used in various application scenarios, such as digital advertising, information release, commercial display, and entertainment activities. By providing a larger display area and richer display effects, this system can meet a variety of different visual needs. In the process of multi-screen splicing, a device called a locking assembly is required to tightly combine two adjacent screens together.

[0003] The patent with publication number CN214226403U discloses a lock for splicing LCD screens, and its technical solution is: it includes a first box body, a lock mechanism is provided on one side of the first box body, and the lock mechanism includes a second box body. The beneficial effect of the utility model is: by respectively passing two wedge blocks on one side of the first box body through two slot holes on one side of the second box body, and making the two wedge blocks extend into the two grooves respectively, the first box body and the second box body are fixed, and the two spliced ​​LCD screens are also fixed. When the two spliced ​​LCD screens need to be disassembled, the two spliced ​​LCD screens can be disassembled by pushing the first handle. The two spliced ​​LCD screens can be connected in this way, so that the two spliced ​​LCD screens can be installed and disassembled very conveniently. When one spliced ​​LCD screen is damaged, the spliced ​​LCD screen can be conveniently repaired, thereby improving the repair efficiency of the spliced ​​LCD screen.

[0004] Although the above-mentioned prior art makes it very convenient to install and disassemble two spliced ​​LCD screens, the lock only supports limited splicing methods, such as linear splicing or matrix splicing, and lacks sufficient flexibility. If a non-standard splicing layout is required, such as an arc or ring layout, the user needs to use special brackets and connectors, which increases the difficulty and cost of splicing. In view of this, we propose a multi-mode splicing screen lock assembly. Utility Model Content
