Quick assembly type skylight drain pipe joint adopting double-lip wedge-shaped sealing

Abstract

The invention discloses a quick assembly type skylight drain pipe joint adopting double-lip wedge-shaped sealing. The quick assembly type skylight drain pipe joint adopting double-lip wedge-shaped sealing comprises a skylight and a skylight drain pipe joint assembly, wherein a boss of a skylight drain opening is arranged on the skylight, the skylight drain pipe joint assembly comprises a double-lip wedge-shaped sealing ring, wedge-shaped block clamping jaws, an anti-rotation platform, an inverted buckle and a conical face, the double-lip wedge-shaped sealing ring is arranged on the outer wallof the skylight drain pipe joint assembly in a sleeving mode, the skylight drain pipe joint assembly is inserted into one end of the skylight, and the wedge-shaped block clamping jaws are far away from the end of the skylight. According to the quick assembly type skylight drain pipe joint adopting double-lip wedge-shaped sealing, through the double-lip wedge-shaped sealing ring, under the condition that the requirement for sealing performance is met, the resistance generated during installation is small, the double-lip wedge-shaped sealing ring cannot deform abnormally through cooperation of the anti-rotation platform and the boss of the skylight drain opening, and meanwhile, the sealing reliability of the double-lip wedge-shaped sealing ring can be improved. The quick assembly type skylight drain pipe joint is suitable for an automobile.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a double-lip wedge-shaped quick-assembly sunroof drain pipe joint. Background technique [0002] The car sunroof is installed on the roof, which can effectively circulate the air in the car and increase the entry of fresh air. At the same time, the car sunroof can also broaden the field of view and meet the shooting needs of mobile photography. Car sunroofs can be roughly divided into: sliding outside, built-in, built-in and turned-out, panoramic and curtain. It is mainly installed on commercial SUVs, sedans and other vehicles. Therefore, the drainage structure on the car sunroof is very important. The car sunroof connects the sunroof drain pipe to discharge the water entering the sunroof gutter. The connection between the skylight drain pipe and the skylight adopts the traditional method of natural tightening of the rubber tube, which has difficulty in assembly and the risk...

AI Technical Summary

Problems solved by technology

The connection between the skylight drain pipe and the skylight, the traditional mode is to adopt the natural tightening method of the rubber tube, which has the difficulty of assembly and the risk of falling off due to vibration in the later stage

An improved solution is to make an outwardly expanding accommodation cavity at the drain port of the skylight, and then fix it with a metal snap ring. This method requires assembly tools, and the assembly is complicated and time-consuming

An improved way is to use an O-ring seal, which makes the assembly easier, but the O-ring is easily deformed due to the rotation of the joint during the assembly process, resulting in seal failure
