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] to 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 . In this embodiment, the end surface 111 of the other end of the cylindrical portion...

Abstract

The invention relates to a seal ring and a lamp using the same. The seal ring comprises a cylinder part and a circular truncated cone part along the axial direction, wherein the circular truncated cone part extends in the manner of closure front one end of the cylinder part along the axial direction; the middle parts of the cylinder part and the circular truncated cone part are respectively penetrated to form the inner circumferential face of the seal ring; and the inner circumferential face, the end face of the other end of the cylinder part and the outer side face of the circular truncated cone part are respectively the seal face of the seal ring. The seal ring is provided with the cylinder part and the circular truncated cone part; the middle parts of the cylinder part and the circular truncated cone part are penetrated to form the inner circumferential face of the seal ring; the inner circumferential face, the end face of the other end of the cylinder part and the outer side face of the circular truncated cone part are the three seal faces of the seal ring; at the joint of a cable and a shell, external forces are respectively applied to the three seal faces, and the three faces are stressed; the seal pressure is even; the seal performance is good, and the protection performance is stable, thereby, a good seal effect is performed, water and dust are effectively prevented, and the lamp is protected well.

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 ...
