Abstract
The utility model relates to a high-airtightness corrugated pipe connection structure, comprising an electromagnetic valve (1) and a corrugated pipe (2). The high-airtightness corrugated pipe connection structure is characterized by further comprising a rubber pipe opening sleeve (3), wherein the head of the electromagnetic valve (1) is inserted into the rubber pipe opening sleeve (3), and the head of the rubber pipe opening sleeve (3) is inserted into the corrugated pipe (2). According to the high-airtightness corrugated pipe connection structure disclosed by the utility model, the electromagnetic valve and the corrugated pipe are connected through the rubber pipe opening sleeve, thus the electromagnetic valve, the corrugated pipe and the rubber pipe opening sleeve are simply assembled and dissembled and match through inner and outer grooves and inner and outer bulges so that sealing performance of the whole connection structure is largely improved.
Description
Technical field
The utility model relates to a kind of bellows linkage structure, relates in particular to linkage structures such as a kind of and machine oil pipe, canister connecting tube, air duct.Belong to automobile manufacturing field.
Background technique
Machine oil pipe in the general automobile, canister connecting tube, air duct etc. all directly are connected with bellows through solenoid valve.At first bellows and solenoid valve are connected; Again both connection parts are fixed with clip, adopted this mode to connect that not only sealing is poor, and the efficient of assembling and dismounting is very low; Spend very big strength could realize connection between the two, time-consuming effort again.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of sealing higher, and assembly and disassembly is the bellows linkage structure comparatively easily.
The purpose of the utility model is achieved in that a kind of high leak tightness bellows linkage structure, and it comprises solenoid valve, bellows and rubber pipe muzzle, and the head of said solenoid valve inserts in the rubber muzzle, and the head of said rubber pipe muzzle inserts in the bellows.
Be to improve the sealing between solenoid valve and the rubber pipe muzzle, be provided with the protruding I of at least one circle at the head of said solenoid valve, the inner hole wall of rubber pipe muzzle is provided with the groove I that matches with said protruding I.
For improving the sealing between rubber pipe muzzle and the bellows; The outer surface of said rubber pipe muzzle is provided with at least one circle groove II and the protruding II of at least one circle, and the inner hole wall of bellows is provided with protruding III and the groove III that matches with said groove II and protruding II.
Compared with prior art, the beneficial effect of the utility model is:
The utility model connects solenoid valve and bellows through the rubber pipe muzzle, and not only the equipment dismounting is simple, and the cooperation of inside and outside groove and interior outer lug makes that the sealing of whole linkage structure has obtained improving greatly between the three.。
