Abstract
The utility model discloses a connecting structure for a vehicle gasoline pipe and a muffler pipe, which consists of a metal steel tube and a muffler pipe. The connecting structure is characterized in that two or more annular projections are formed on the end head of the metal steel tube; and contraction parts are inserted into two sides of the muffler pipe on an annular raised section. The connecting structure ensures that the connection reliability of the metal steel tube and the muffler tube is greatly enhanced, and the cost is reduced.
Description
Technical field:
The utility model relates to auto parts and components, specifically is the linkage structure of a kind of automobile oil pipe and hush tube.
Background technique:
At home, automobile steel pipe and hush tube linkage structure are at present: insert the ring-shaped work pieces of a special use at steel tube head, this becomes T-joint is to be formed by the metal machining, then hush tube is inserted ring-shaped work pieces and carries out snap close.This complex structure, waste material, many, the increase cost of production of manufacturing procedure, at inner wall of metal tube and ring-shaped work pieces surface of contact, take place twice at the ring-shaped work pieces inwall with the hush tube surface of contact and contact, any one face contact is not tight, the hush tube obscission will occur.
Summary of the invention:
The utility model provides a kind of improved automobile steel pipe and hush tube linkage structure, solves steel pipe and hush tube linkage structure complexity, cost problem of higher, and hush tube for once contacts with the metal steel duct, the minimizing hush tube probability that comes off.
The scheme that the utility model adopts is:
The linkage structure of a kind of automobile oil pipe and hush tube, comprise metal steel pipe, hush tube, it is characterized in that: form one or more annular protrusions near tip position on the metal steel pipe, hush tube inserts in the metal steel pipe from the end, and the metallic steel pipe end is a contraction flow region.
Described hush tube inserts the position that reaches first annular protrusion in the metal steel pipe.
Annular protrusion on the described metal steel pipe is by the shaping die extrusion modling, and the contraction flow region of described metallic steel pipe end is radially locked from the metallic steel tube outer surface by special purpose machine tool and formed.
Advantage of the present utility model:
The pulling-out force increase that is connected between the Placement that the utility model provides, hush tube and metal steel pipe is bigger, is connected closelyr between metal steel pipe and hush tube, and the reliability of connection is strengthened greatly, reduces the hush tube probability that comes off.Compare with other linkage structures, can finish the processing that the metal steel pipe is connected with hush tube in the short period of time, can in steel pipe, connect reliably, realized with low costly, connect reliable advantage.
Description of drawings:
Fig. 1 is the utility model cross-sectional view:
Embodiment:
Referring to Fig. 1:
The linkage structure of automobile steel pipe and hush tube is made up of metal steel pipe 1, hush tube 2.Annular protrusion 3 of moulding and 4 on the metal steel pipe 1, hush tube 2 are inserted into certain-length in the metal steel pipe 1, are radially locked at steel pipe 1 outer surface by special purpose machine tool, form contraction flow region 5, and so, then metal steel pipe 1 links together very securely with hush tube 2.
Belt protruding 3,4 structures of metal steel pipe 1 are by the shaping die extrusion modling;
Claims (2)
1, the linkage structure of a kind of automobile oil pipe and hush tube, comprise metal steel pipe, hush tube, it is characterized in that: form one or more annular protrusions near tip position on the metal steel pipe, hush tube inserts in the metal steel pipe from the end, and the metallic steel pipe end is a contraction flow region.
2, the linkage structure of automobile oil pipe according to claim 1 and hush tube is characterized in that: described hush tube inserts the position that reaches first annular protrusion in the metal steel pipe.
