Abstract
The utility model discloses a connecting structure of an automobile oil pipe, and the connecting structure comprises a metal steel pipe, a rubber pipe and a metal sleeve. The connecting structure is characterized in that two or more than two annular bulges are moulded on the end head of the metal steel pipe; the rubber pipe is sleeved on the annular bulge segment; the outer part of the rubber pipe sleeved on the annular bulge segment is provided with the metal sleeve; and the two sides of the metal sleeve corresponding to the annular bulges of the metal steel pipe are provided with contracting parts. The connecting structure makes the reliability of the connection of the metal steel pipe and the rubber pipe be greatly strengthened, and so can be suitable for a higher pressure and a wider temperature scope.
Description
Technical field
The utility model relates to a kind of auto parts and components, specifically is a kind of structure of automobile oil pipe.
Background technique
At home, the automobile oil pipe linkage structure is at present: at one one-tenth T-joint of steel tube head welding, this becomes T-joint is to be formed by the metal machining, and insert in the sebific duct steel tube forming termination, and with metallic sheath locking, and this metallic sheath also forms for the metal machining.This complex structure, waste material, many, the increase cost of production of manufacturing procedure.
Improvement as said structure, be directly at metallic steel pipe end moulding one annular protrusion, the annular protrusion section is with sebific duct, and there is metallic sheath the sebific duct outside that is enclosed within the annular protrusion section, contraction, metallic sheath are all arranged is impact briquetting the both sides of the annular protrusion of corresponding metal steel pipe places on the metallic sheath.This structure has solved the problem that complex structure, waste material, manufacturing procedure are many, increase cost of production.But some vehicle oil pipe requires pressure height, serviceability temperature condition harshness, makes this reliability of structure still not enough.
The model utility content
The utility model provides a kind of improved automobile oil pipe linkage structure, except that solving oil tube connection structure complexity, cost problem of higher, solves the problem of pressure-bearing height, broad application temperature range simultaneously.
The scheme of the utility model technical solution problem is:
A kind of linkage structure of automobile oil pipe, it is made up of metal steel pipe, sebific duct, metallic sheath and it is characterized in that: form two or surpass two annular protrusion at the metallic steel pipe end, the annular protrusion section is with sebific duct, there is metallic sheath the sebific duct outside that is enclosed within the annular protrusion section, and there is contraction flow region at place, the both sides of the annular protrusion of corresponding metal steel pipe on the metallic sheath.
The linkage structure of described automobile oil pipe is characterized in that: metallic steel pipe end moulding one annular retaining ring, there is an annular retaining edge sebific duct end of retaining outside being set in annular protrusion with annular retaining ring adjacent metal cover end.
Tail end at metallic sheath can have contraction and not shrink two kinds, and metallic sheath is impact briquetting.
Two annular protrusions of metal steel pipe are inserted in the sebific duct, put metallic sheath, lock to form on special mechanical equipment.
Placement of the present utility model, adopt two annular protrusions, the pulling-out force increase that is connected between sebific duct and metal steel pipe is bigger, has increased a seal point between metal steel pipe and sebific duct, the reliability of connection is strengthened greatly, thereby can adapt to higher pressure and wideer temperature range.Compare with other linkage structures, can finish the processing of the annular protrusion shaping end of metal steel pipe in the short period of time, can in metallic sheath, connect reliably, realized with low costly, connect reliable advantage.

Embodiment
Referring to Fig. 1.
Figure
The linkage structure of automobile oil pipe is made up of metal steel pipe 1, metallic sheath 2, sebific duct 3.Form two annular protrusions 4, an annular retaining ring 5 on the metal steel pipe 1, metal steel pipe 1 is inserted in the sebific duct 3, sebific duct 3 is enclosed within on two annular protrusions 4, sebific duct 3 front ends push up annular retaining ring 5, are with metallic sheath 2 outside sebific duct 3, and metallic sheath 2 front ends have the annular retaining along 7, radially lock at metallic sheath 2 outer surfaces by special purpose machine tool, form contraction flow region 6, so, then metal steel pipe 1 links together very securely with sebific duct 3.
Belt protruding 4, annular retaining ring 5 structures of metal steel pipe 1 are by the shaping die extrusion modling;
Claims (2)
1. the linkage structure of an automobile oil pipe, it is made up of metal steel pipe, sebific duct, metallic sheath and it is characterized in that: form two or surpass two annular protrusion at the metallic steel pipe end, the annular protrusion section is with sebific duct, there is metallic sheath the sebific duct outside that is enclosed within the annular protrusion section, and there is contraction flow region at place, the both sides of the annular protrusion of corresponding metal steel pipe on the metallic sheath.
2. the linkage structure of automobile oil pipe according to claim 1 is characterized in that: metallic steel pipe end moulding one annular retaining ring, the sebific duct end of retaining being set in annular protrusion outside has an annular to keep off the edge with annular retaining ring adjacent metal cover end.
