The invention relates to a cabin dome light installation structure, comprising: a base, a sealing ring is arranged on the base; a lampshade, the lampshade is arranged on the base, and the sealing ring is pressed on the base; a fixing ring is arranged on the base , the lampshade is provided with a fixing bolt corresponding to the fixing ring, the fixing bolt passes through the lampshade and is rotatably connected with the lampshade, the fixing bolt is sealed with the lampshade, and the fixing bolt can be inserted into the fixing bolt In the ring; the fixing bolt is fixedly provided with a locking rod at one end inside the lampshade, the locking rod is perpendicular to the fixing bolt, and the position of the fixing ring corresponding to the locking rod is provided with a vertical first notch, and the fixing A second notch is horizontally arranged on the ring, the first notch communicates with the second notch, and the locking rod can slide in the first notch and the second notch. The installation structure of a cabin dome light provided by the invention avoids the failure of the sealing ring caused by the excessively large gap between the lamp shade and the base.
Description
technical field [0001] The invention relates to the technical field of lighting devices, in particular to a dome light installation structure. Background technique [0002] The dome light is a light with a well-sealed and waterproof structure. It is mostly used in wet places such as engine rooms, cargo holds, bathrooms, and work places, as well as on the top of external passages and open-air locations. [0003] In the existing dome light installation structure, the lampshade is clamped on the base through the clamping parts, and the sealing ring is pressed on the base through the lampshade, and the sealing ring is squeezed by force to play a sealing role. [0004] However, in the existing dome light installation structure, the clamping structure of the lampshade and the base needs to be deformed before it can be snapped into the groove. The clamping structure is easily damaged, resulting in the loss of the sealing effect of the sealing ring. The dome light installation struc...
