Description

Technical Field

[0001] The utility model belongs to the technical field of installation, and particularly relates to a connection and fixing structure. Background Art

[0002] LED display is a flat display device that uses LED as a light source. When installing an LED display, different connection and fixing structures need to be selected according to different specifications of LED display screens. Some connection and fixing structures are not very flexible, so there are the following deficiencies when using them:

[0003] 1. Some existing connection and fixing structures are mostly integrated connection and fixing structures. It is not convenient to splice the connection and fixing structures, and may not be able to adapt to the combination of LED display screens of different sizes and shapes, resulting in greater limitations. They may be restricted by the connection structures, resulting in the splicing process being not flexible and convenient enough.

[0004] 2. At the same time, some connection and fixing structures are not stable enough, which may cause the LED display to shake during use. Unstable connection and fixing structures may require more frequent maintenance and adjustments, increasing maintenance costs and workload.

[0005] For this purpose, we propose a connection and fixing structure. Utility Model Content
