Problems solved by technology

[0003] However, the hollow seal has the following two disadvantages: 1. The air inside the inner hole of the hollow seal cannot be discharged in time when the product is installed, but it will be discharged slowly over time, resulting in a gradual decrease in the sealing contact force and resulting in seal failure ;2. The seal rebounds slowly after being impacted

Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0045] Such as figure 1 As shown, the hollow seal 10 of this embodiment includes a top 12 , an inner bore 14 , a middle 16 and a bottom 18 . The hollow sealing member 10 can be an annular sealing ring, a square sealing ring or a strip sealing ring, or a gasket. In addition, in another specific embodiment of the present invention, the interior of the hollow sealing member of the present invention has a connected cavity, and the cross section of the cavity is elliptical. In other words, the hollow seal is a seal with a closed shape. Common seals with closed shapes include ring seals, squa...

Abstract

The present invention relates to a hollow seal and lamp. The hollow seal (10) comprises an elliptic inner hole (14); an elliptic long shaft (Y) of the inner hole (14) is arranged along compression directions (51, 52) of the hollow seal. An outer surface at a top part (12) of the hollow seal is an arc surface. A middle part (16) of the hollow seal is provided with a back-off part for fixing the hollow seal. The width of a bottom (18) of the hollow seal is gradually reduced downwardly along the elliptic long shaft (Y) of the inner hole. The hollow seal and lamp of the present invention can avoid the sealing failure slowly caused by that air in the inner hole of the hollow seal can not be discharged or the air is rebounded after being impacted; the reliability of seal is improved.

Description

technical field [0001] The present invention relates to hollow seals. Furthermore, the invention relates to a luminaire with a hollow seal. Background technique [0002] At present, in the development of new products, in order to save cost, reduce weight or meet customer's appearance design requirements, the product shell is usually designed to be thinner. This easily causes the housing to deform under the reaction force of the seal. This phenomenon is especially evident on plastic housings, and thus leads to seal failure. In order to solve such problems, hollow seals are often used. In addition, products with thinner shells are often sealed with hollow seals. [0003] However, the hollow seal has the following two disadvantages: 1. The air inside the inner hole of the hollow seal cannot be discharged in time when the product is installed, but it will be discharged slowly over time, resulting in a gradual decrease in the sealing contact force and resulting in seal failur...
