Abstract

The utility model relates to a car tail pipe and decoration cover assembly coupling assembling, including decorating cover core pipe and decorating the decoration cover assembly that the cover is constituteed, the core pipe strap spring spacer pin of oriented evagination on tail pipe's pipe wall, two sets of circumference limit point intermediate formation axial spacing grooves, and axial limit point is located the inner end of axial spacing groove, the inward protruding slide that 4 equipartitions were parallel to each other on the inner wall of decoration cover core pipe, there is core pipe strap spring in the middle of 2 archs, 4 inward protruding slides that are parallel to each other decorating cover core pipe are arranged in tail pipe's axial spacing groove, and inner end and axial limit point outside apical grafting, core pipe strap spring and core pipe strap spring spacer pin joint. The advantage is novel structure, need not through frock clamp can to tail pipe with decorate the cover assembly and install fast, need not the welding wire welding, reduce the defective products rate, decorating cover assembly and tail pipe, to pass through the jump ring spacing, has obvious interchangeability advantage.

Description

A kind of exhaust tail pipe of automobile and Decorative Cover assembly coupling assembly

Technical field

This utility model belongs to automobile exhaust system component, refers in particular to the connection of a kind of tailpipe and Decorative Cover assembly Component.

Background technology

As social development, the continuous progress of science and technology, automobile appearance renewal speed are constantly accelerated, consumer is to riding Car outward appearance individual requirement more and more higher, family-sized car are gradually evolved into function, amusement and outward appearance simultaneously from Lay Importance on Practical The popular consumer goods of weight.Tail pipe decorating cover should meet passenger car as the primary decoration part of Exhaust System of Passenger Car The test of gas extraction system endurance quality, meets acoustics laws and regulations requirement, matches with car load appearance and modeling again, is that whole structure adds Point.

With Decorative Cover assembly connected mode to be welded to connect, tail pipe and Decorative Cover assembly pass through conventional tailpipe at present Frock clamp is fixed, and tail pipe insertion Decorative Cover core pipe is carried out segmentation welding.This kind of connected mode is entered except needing frock clamp Row positioning welding, also needs to carry out Decorative Cover assembly surface welding slag splashing protection, Decorative Cover during welding Decorative Cover Damage during vehicle use can only cut soldering again, and interchangeability is poor.

The content of the invention

This utility model provides a kind of exhaust tail pipe of automobile and Decorative Cover assembly coupling assembly, to solve tailpipe with dress Decorations cover assembly, need to be by frock clamp is spacing and welding in connection, and existing needs to carry out Decorative Cover assembly surface welding slag and fly Splashing protection, the poor problem of interchangeability.

This utility model is adopted the technical scheme that：Including the Decorative Cover assembly of Decorative Cover core pipe and Decorative Cover composition, Core pipe jump ring spacer pin outwardly convex on the tube wall of tailpipe, be evenly equipped with the tube wall of tailpipe 4 it is cambered outwards Axial limiting point, apart from the equal apart from h of tailpipe inner end, core pipe jump ring spacer pin is apart from inner end for 4 axial limiting points Apart from H more than the axial limiting point apart from tailpipe inner end apart from h, core pipe jump ring spacer pin is located at two adjacent axles To in the middle of limit point, outwardly convex two groups are distinguished positioned at the outside of 2 axial limiting points of core pipe jump ring spacer pin both sides all To limit point, per group of circumferential limit point is made up of two cambered outwards limit points, this two groups circumferential limit point intermediate formation axial directions Stopper slot and axial limiting point are located at the inner end of axial limiting groove, and two axial limiting grooves are parallel to each other, Decorative Cover core pipe it is interior The uniform 4 inside raised slideways being parallel to each other on wall, have core pipe jump ring, 4 phases of Decorative Cover core pipe in the middle of 2 projections Mutually parallel inside raised slideway in the axial limiting groove of tailpipe, and inner end and axial limiting point on the outside of apical grafting, Core pipe jump ring and core pipe jump ring spacer pin clamping.

The utility model has the advantages that structure is novel, need not pass through frock clamp can be to tailpipe and Decorative Cover assembly Fast Installation is carried out, is welded without the need for welding wire, save welding wire use cost, reduced gas extraction system entirety installation time, lift production capacity； Decorative Cover assembly can be mounted directly in client, it is to avoid in welding, transportation, external factor is caused to Decorative Cover surface Damaging, reducing defective products rate, Decorative Cover assembly is spacing by jump ring with tailpipe, card need to be only pushed aside when changing Decorative Cover assembly Spring is replaceable, compared with welding manner, with obvious interchangeability advantage.

Specific embodiment

It is including the Decorative Cover assembly 1 that Decorative Cover core pipe 101 is constituted with Decorative Cover 102, oriented on the tube wall of tailpipe 2 The core pipe jump ring spacer pin 201 of evagination, is evenly equipped with 4 cambered outwards axial limiting points 202 on the tube wall of tailpipe 2, and this 4 , apart from the equal apart from h of tailpipe inner end, core pipe jump ring spacer pin 201 is big apart from H apart from inner end for individual axial limiting point 202 In the axial limiting point 202 apart from tailpipe inner end apart from h, core pipe jump ring spacer pin 201 is located at two adjacent axial directions In the middle of limit point 202, the outside difference positioned at 2 axial limiting points 202 of 201 both sides of core pipe jump ring spacer pin is outwardly convex Two groups of circumferential limit points 203, per group of circumferential limit point 203 are made up of two cambered outwards limit points, this two groups circumferential limit points 203 intermediate formation axial limiting grooves 204, and axial limiting point 202 be located at axial limiting groove 204 inner end, two axial limitings Groove is parallel to each other, and on the inwall of Decorative Cover core pipe 101, the uniform 4 inside raised slideways 10101 being parallel to each other, convex at 2 4 inside raised slideways 10101 being parallel to each other for having core pipe jump ring 10102, Decorative Cover core pipe in the middle of rising are located at exhaust tail In the axial limiting groove 204 of pipe, and 202 outside apical grafting of inner end and axial limiting point, core pipe jump ring 10102 is spacing with core pipe jump ring 201 clamping of pin；

The tailpipe caliber scope is 40-55mm；

The tailpipe thickness range is 0.8-1.2mm；

The Decorative Cover thickness range 0.5-0.8mm；

Decorative Cover assembly and tailpipe are spacing by jump ring, need to be only pushed aside by jump ring more when changing Decorative Cover assembly Change, compared with welding manner, with obvious interchangeability advantage.
