Abstract

The invention discloses an automotive air conditioner drainage pipe sealing ring, and belongs to the technical field of automobile making. A first boss stretching out in the radial direction is arranged at one end of the automotive air conditioner drainage pipe sealing ring, a chamfer forming an included angle alpha with the horizontal direction is formed on the inner wall, corresponding to the end of the first boss, of the sealing ring, a second boss stretching out in the radial direction is arranged at the other end of the sealing ring, the outer wall surface of the second boss is a conical surface, a groove vertical to a plane is formed between the first boss and the second boss, the inner diameter of the through hole of the sealing ring is smaller than the outer diameter of a drainage pipe, and the width of the groove is smaller than the thickness of automobile metal plates. According to the automotive air conditioner drainage pipe sealing ring, the problems that the drainage pipe is difficult to mount, and the sealing ring is prone to falling off and difficult to assemble are solved.

Description

Technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a drainage pipe sealing ring of an automobile air conditioner. Background technique [0002] The car air conditioner has a drain pipe, and the joint between the drain pipe and the body is equipped with a sealing ring. Due to the vibration generated when the car is running, the body sheet metal, the sealing ring and the drain pipe are required to be closely matched. The existing sealing ring It is a cylindrical body, and the inner diameter of the center hole opened along the axis is also the same. This kind of sealing ring will produce: the drainage pipe is difficult to insert, when the outer wall of the sealing ring and the body sheet metal have a gap, the sealing ring is easy to fall off and the sealing ring and the body The problem that the sealing ring is difficult to assemble when the interference of the sheet metal is too large. Summary of the invention [0003] ...
