Description

Spliced screen unit with dustproof sealing design Technical Field The utility model belongs to the technical field of display equipment, and particularly relates to a spliced screen unit with a dustproof sealing design. Background In the application process of the spliced screen unit, the dustproof sealing design has important practical significance for improving the running stability and the service life of equipment. The spliced screen unit is widely applied to scenes such as monitoring centers, command scheduling, exhibition and exhibition, but the installation environment of the spliced screen unit is mostly in an open or semi-open state and is easily affected by dust invasion, so that dust accumulation on the surface or an internal structure of the screen is caused, and the display effect and the equipment performance are affected. Therefore, how to realize an effective dust seal design is a problem to be solved in the current spliced screen units. Upon retrieval, a "dust seal and projector" of patent number CN106886121B, published as 2023-09-08, is disclosed. According to the scheme, the structure that the end face sealing section is combined with the cavity sealing section is arranged, so that the sealing piece can adapt to the inclined movement of the lens barrel, and dust is effectively prevented from entering the surfaces of the optical machine component and the optical element.
