Problems solved by technology

However, the sealing ring with a rectangular cross-section has poor sealing performance at the connection between the cable and the housing, and the protection performance is unstable. It cannot effectively seal the lamp and cannot meet the waterproof and dustproof requirements, which seriously affects the dustproof and waterproof effect of the lamp.

Embodiment Construction

[0022] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] figure 1 It is a structural schematic diagram of the seal ring in one embodiment and the seal ring in a preferred embodiment using the seal ring. figure 2 yes figure 1 A cross-sectional view of the sealing ring structure along the axial direction.

[0024] combine figure 1 and figure 2 , the sealing ring 100 is made of rubber, and its cross-section along the axial direction is wedge-shaped through the middle, which includes a cylinder part 110 and a circular frustum part 120 that is gathered and extended from one end of the cylinder part 110 along its axial direction. Both the cylindrical part 110 and the middle part of the circular truncated part 120 pass through to form the inner peripheral surface 130 of the sealing ring 100 . The outer peripheral surface of the cylinder part 110 is indented to form an annular g...

Abstract

The invention relates to a seal ring and a lamp using the same. The seal ring comprises a column part in the axial direction; the middle part of the column body is penetrated to form an inner circumference surface of the seal ring; the outer circumference surface of the column body depresses internally to form a groove; and the inner circumference surface and the bottom surface of the groove are both sealing surfaces of the seal ring. According to the invention, the outer circumference surface of the column part of the seal ring depresses to form the groove, the middle part of the column part is penetrated to form the inner circumference surface of the seal ring, the inner circumference surface and the bottom surface of the groove are two sealing surfaces of the seal rings, external force is respectively applied to the two sealing surfaces at the connection part between a cable and a shell, so that the seal ring is stressed from two surfaces, and thus sealing pressure is uniform, sealing performance is favorable, protection performance is stable, and a favorable sealing effect is achieved; and the seal ring can be used for effectively preventing water and dust and plays a favorable protection role in the lamp.

Description

【Technical field】 [0001] The invention relates to a sealing device, in particular to a sealing ring and a lamp using the sealing ring. 【Background technique】 [0002] At present, during the use of the lamp, in order to ensure that the lamp is suitable for various environments and protect the safety of the internal structure of the lamp, it is necessary to use a sealing structure to seal the inside of the lamp so as to be dustproof and waterproof. [0003] Most of the traditional lighting products use a sealing ring with a rectangular cross-section to make a sealing structure for sealing. However, the sealing ring with a rectangular cross-section has poor sealing performance at the connection between the cable and the housing, and the protection performance is unstable. It cannot effectively seal the lamp and cannot meet the waterproof and dustproof requirements, which seriously affects the dustproof and waterproof effect of the lamp. . 【Content of invention】 [0004] In ...
