AI Technical Summary

Technical Problem

The existing crankcase ventilation pipe is made of rubber tubing, which requires clamps for fastening, resulting in wasted assembly time and a high risk of leakage.

Method used

It adopts a nylon ventilation duct body and a DC quick-connect connector, which is connected by pressing with a normal temperature bamboo joint connector. The other end of the quick-connect connector is directly assembled with the engine connector, and the sealing ring and spring are combined to improve the sealing performance.

Benefits of technology

It reduces assembly time, improves assembly efficiency and reliability, prevents leakage, and enhances service life and after-sales service convenience.

Abstract

The utility model discloses a quick plug type crankcase ventilation pipe which comprises a ventilation pipe body and a quick plug connector, the ventilation pipe body is made of nylon materials, and the ventilation pipe body is used for being connected with a crankcase; one end of the quick-plug connector is fixedly connected with the ventilation pipe body into a whole, and the other end of the quick-plug connector is used for forming a quick-plug structure with an engine bulge connector. According to the quick-insertion type crankcase ventilation pipe, the ventilation pipe body is made of conventional nylon materials, the leakage risk is avoided, one end of the DC type quick-insertion connector and the ventilation pipe body made of the nylon materials are fixedly connected into a whole through the normal-temperature bamboo joint connector press-fitting technology, and the ventilation pipe body is made of the nylon materials. The other end of the quick-plug connector can be directly assembled with the engine connector in a quick-plug mode, and compared with a mainstream assembly mode of a rubber pipe and a clamp on the market at present, on the basis that the leakage problem is solved, the assembly working hours can be reduced, so that the assembly is more efficient, the reliability is more excellent, and the after-sales service is more convenient.
