Abstract
The utility model relates to an automobile oil pipe connecting mechanism, comprising a rubber pipe. The rubber pipe is sleeved on a pipe body of a metal steel pipe; an annular bulge is formed on the pipe body of the metal steel pipe; an annular groove is formed on the end part of the metal steel pipe; a metal sleeve is sleeved outside the rubber pipe; the end part of the metal sleeve is provided with an annular lock catch which is blocked in the annular groove of the metal steel pipe; and a position of the metal sleeve, which corresponds to the annular bulge of the metal steel pipe, is provided with a contraction part. Compared with other connecting structures, the utility model has the advantages that the annular bulge of the metal steel pipe can be processed within a shorter time; the annular groove is simply processed; the metal sleeve can enter the annular groove at the end part of the metal steel pipe directly through a die pressing lock so as to realize reliable connection in the metal sleeve; and low cost and reliable connection are achieved.
Description
Technical field
The utility model relates to a kind of auto parts and components, especially a kind of automobile oil pipe linkage structure.
Background technique
At home, the automobile oil pipe linkage structure is in the technology 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.Conventional art have complex structure, easily cause waste of material, manufacturing procedure many, increase problem such as cost of production.
The model utility content
The purpose of this utility model provides a kind of automobile oil pipe linkage structure, to solve the automobile oil pipe complex structure under the prior art, easily causes waste of material, and cost is than problems such as height.
In order to achieve the above object, the technological scheme that the utility model adopted is:
A kind of automobile oil pipe linkage structure, include sebific duct, described glue pipe socket is on the pipe shaft of metal steel pipe, form annular protrusion on the pipe shaft of described metal steel pipe, the end of described metal steel pipe forms annular groove, described sebific duct is with metallic sheath outward, and described metallic sheath end has annular snap close to be stuck in the annular groove of metal steel pipe, and there is contraction flow region described metallic sheath and position, metallic steel pipe ring shape projection corresponding part.
The annular groove edge at described metallic steel pipe end place is processed with annular retaining ring, and described metallic sheath end is against on the annular retaining ring.
The annular retaining ring of the annular protrusion of described metal steel pipe and metal steel pipe is by the shaping die extrusion modling.
In the utility model, metallic sheath directly embeds among the annular groove of metallic steel tube end, metallic sheath directly adopts the mould extruding to enter in the annular groove of metallic steel tube end, metal steel pipe pipe shaft adopts two annular protrusions, the pulling-out force increase that is connected between sebific duct and metal steel pipe is bigger, increase 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.
The utility model is compared with other linkage structures, can finish the processing of the annular protrusion of metal steel pipe in the short period of time, annular groove processing is simple, metallic sheath directly presses lock to enter in the annular groove of metal tube end by mould, can in metallic sheath, connect reliably, realized with low costly, connected reliable advantage.
Description of drawings
Fig. 1 is the utility model sectional view.
Embodiment
A kind of automobile oil pipe linkage structure, include sebific duct 1, sebific duct 1 is enclosed within on the pipe shaft of metal steel pipe 2, form annular protrusion 3 on the pipe shaft of metal steel pipe 2, the end of metal steel pipe 2 forms annular groove 4, be with metallic sheath 5 outside the sebific duct 1, metallic sheath 5 ends have annular snap close 6 to be stuck in the annular groove 4 of metal steel pipe, and metallic sheath 5 has contraction flow region 7 with position, metal steel pipe 2 annular protrusions, 3 corresponding part.Annular groove 4 edges of metal steel pipe 2 ends are processed with annular retaining ring 8, and metallic sheath 5 ends are against on the annular retaining ring 8.The annular protrusion 3 of metal steel pipe 2 and the annular retaining ring 8 of metal steel pipe 2 are by the shaping die extrusion modling.
Can not want annular retaining ring 8 in actual applications yet, only rely on the edge of annular groove 4 to position.
