Embodiment Construction

[0024] see figure 1 , the sealing structure of one embodiment includes a supporting body 10 provided with a groove 12, a sealing ring 20 arranged in the groove 12, and a housing 30 covered on the supporting body 10, and the edge of the housing 30 is provided with The reinforcing rib 32 abutting against the sealing ring 20 .

[0025] Please refer to figure 2 , the supporting body 10 fixedly supports the sealing ring 20 and the housing 30 , and its edge is inwardly recessed to form a groove 12 suitable for the sealing ring 20 .

[0026] Please refer to image 3 , the sealing ring 20 is used to seal the space to be sealed between the support body 10 and the housing 30 to prevent the intrusion of foreign substances or the leakage of substances in the space to be sealed. In order to ensure the sealing effect between the sealing ring 20 and the supporting body 10 , the sealing ring 20 is placed in the groove 12 of the supporting body 10 , and in a preferred embodiment, the seali...

Abstract

The invention discloses a sealing structure which comprises a support body with a groove, a sealing ring arranged in the groove, and a housing covered on the support body, wherein the edge of the housing is provided with a reinforced rib supporting against the sealing ring. Because the reinforced rib supports against the sealing ring, the sealing structure and the lamp generate a flat pressing function, and realize uniform compression of the sealing ring, thus the sealing property of the sealing structure is improved.

Description

【Technical field】 [0001] The invention relates to a sealing device, in particular to a sealing structure and a lamp using the sealing structure. 【Background technique】 [0002] In the traditional sealing design, a sealing ring with a rectangular cross-section is often used, and the two sealing surfaces are in contact with the sealing ring to form a sealing structure to prevent the intrusion of foreign objects or the leakage of sealed items. [0003] However, in this traditional sealing structure, when the angle between the sealing surface and the sealing ring is too large, the phenomenon of uneven compression of the sealing ring often occurs, which brings great inconvenience to the assembly of the sealing structure. A large number of defective products are produced. 【Content of invention】 [0004] Based on this, it is necessary to provide a sealing structure with uniform compression. [0005] In addition, it is also necessary to provide a lamp using the above sealing str...
