Abstract
The utility model relates to a connecting structure of a flexible pipe and a rubber pipe in an automobile oil pipe. The connecting structure comprises a plastic flexible pipe and a metal lining pipe assembled into the plastic flexible pipe; at least two annular projections are arranged at one lateral edge of the metal lining pipe; the rubber pipe is sleeved on an annular projecting section of the plastic flexible pipe; a metal sleeve is sleeved outside the rubber pipe; and a contraction portion is arranged on the metal sleeve corresponding to the middles of the annular projections of the metal lining pipe. The connecting structure has the advantages of simple structure, easy manufacturing, convenient oil pipe connecting structure production and assembly and production cost reduction.
Description
Technical field
The utility model relates to a kind of automobile oil pipe, relates in particular to the linkage structure of flexible pipe and sebific duct in a kind of automobile oil pipe.
Background technique
The automobile oil pipe linkage structure is in the prior art: at moulding joint of plastic flexible pipe end assembling, the other end of this moulding joint connects sebific duct; Because this moulding joint is shaped by the metal machining, or plastic injection-moulded shaping.These two kinds of complex structures, waste material increases the production time, has increased cost of production.
Summary of the invention
The utility model technical issues that need to address have provided the linkage structure of flexible pipe and sebific duct in a kind of automobile oil pipe, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: plastic flexible pipe; Comprise that also one is assembled to the metal liner in the plastic flexible pipe; On side of described metal liner, at least two annular protrusion bodies are arranged; Be with sebific duct on the annular protrusion body section of plastic flexible pipe, outside sebific duct, be with metallic sheath; There is contraction flow region the centre of the annular protrusion of corresponding metal liner on the described metallic sheath.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, easy to manufacture, oil tube connection structure production and easy to assembly has reduced cost of production.
Description of drawings
Fig. 1 is the utility model sectional structure chart;
Fig. 2 is a metal liner structural representation among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
By Fig. 1, Fig. 2 as seen: the utility model comprises: plastic flexible pipe 1; Comprise that also one is assembled to the metal liner 3 in the plastic flexible pipe 1; On 3 one sides of described metal liner, at least two annular protrusion bodies 31 are arranged; Be with sebific duct 2 on the annular protrusion body section of plastic flexible pipe 1, outside sebific duct 2, be with metallic sheath 4; There is contraction flow region the centre of the annular protrusion of corresponding metal liner 3 on the described metallic sheath 4;
Described annular protrusion body 31 be about two.
The utility model plastic flexible pipe inserts plastic flexible pipe in the sebific duct adopting the metal liner of packing on the special device of prior art, puts metallic sheath, locks to form on the special-purpose machinery that adopts prior art.
Two annular protrusions are arranged on metal liner, and the left end projection is as sebific duct and metallic sheath assembling and positioning, and metal liner is assembled in the plastic flexible pipe.
The annular protrusion structure of metal liner is by the shaping die extrusion modling; And metallic sheath is by low-carbon (LC) cold drawing drawing and forming.
The utility model makes plastic flexible pipe and very firm being connected of sebific duct.
