Abstract
An adapter assembly for an engine lubrication oil inlet steel pipe comprises a connecting pipe body (1), wherein a sealing annular face (1.1) and a connecting annular wall (1.2) are formed on the outer wall of the connecting pipe body (1), the upper end of the connecting pipe body (1) is provided with an upper hole (1.3) matched with the outer diameter of the engine lubrication oil inlet steel pipe (2) in size, an inner pipe (3) with an inner hole (3.1) smaller than the upper hole (1.3) in inner diameter is further arranged in the middle-lower portion of the connecting pipe body (1), the inner pipe (3) and the connecting pipe body (1) form an integral structure, and the inner hole (3.1) of the inner pipe (3) is coaxial with the upper hole (1.3). The adapter assembly can effectively guarantee the sealing performance when the engine lubrication oil inlet steel pipe is connected with other pipe fittings.
Description
Technical field
The utility model relates to technical field of automobile engine, is specifically a kind of engine lubrication oil-feed steel pipe adapter assembly.
Background technique
When engine lubrication oil-feed steel pipe is connected with other pipe fittings, often by a steel pipe joint, realize connection, this steel pipe joint is provided with small one and large one two endoporus and two endoporus of internal diameter and coaxially arranges, one end of engine lubrication oil-feed steel pipe is one-body molded a tip side, and the external diameter of this tip side is slightly larger than the external diameter of engine lubrication oil-feed steel pipe.During connection, pass through mould, the little interior bore portion of steel pipe joint is withheld on tip side, the imperial palace bore portion of steel pipe joint is withheld on engine lubrication oil-feed steel pipe, final realization and being connected of engine lubrication oil-feed steel pipe after other connection pipe fittings utilize the sealing ring surface that is molded on steel pipe joint outer wall and are connected ring wall and are connected with steel pipe joint, finally, for ensureing the sealing of engine lubrication oil-feed steel pipe and steel pipe joint, the imperial palace bore portion of steel pipe joint is further tightly connected by welding with the position that engine lubrication oil-feed steel pipe is withheld mutually.
When engine lubrication oil-feed steel pipe adopts the steel pipe joint of said structure to connect other pipe fittings, because need adopt mould, steel pipe joint is withheld on the tip side of engine lubrication oil-feed steel pipe, when withholding, the buckle press that mould is applied in steel pipe joint is very large, this buckle press can make to be molded over sealing ring surface on steel pipe joint outer wall and be connected ring wall and deform, thereby affects the sealing that steel pipe joint is connected with other pipe fittings.
Model utility content
The technical problems to be solved in the utility model is, the engine lubrication oil-feed steel pipe adapter assembly of sealability when a kind of can effective guarantee engine lubrication oil-feed steel pipe connection with other pipe fittings is provided.
For solving the problems of the technologies described above, the technological scheme that the utility model provides is: comprise adapter body, on the outer wall of described adapter body, form sealing ring surface and be connected ring wall, the upper end of described adapter body is provided with the upper hole being equipped with mutually with engine lubrication oil-feed outer diameter of steel pipes size, in the middle and lower part of described adapter body, be also provided with the inner tube that endoporus internal diameter is less than hole internal diameter, described inner tube is integral type structure with taking over body, and the endoporus of described inner tube and upper hole coaxially arrange.
Adopt after above structure, the utlity model has following advantage: engine lubrication oil-feed steel pipe of the present utility model with adapter assembly by adapter body is set, in the upper end of taking over body, be provided with the upper hole being equipped with mutually with engine lubrication oil-feed outer diameter of steel pipes size, by hole on this, just can be sleeved on engine lubrication oil-feed steel pipe taking over body, and can further be tightly connected by welding, and be also provided with the inner tube that endoporus internal diameter is less than hole internal diameter in the middle and lower part of adapter body, this inner tube is integral type structure with taking over body, and the endoporus of inner tube and upper hole coaxially arrange, that is to say that this inner tube is equivalent to the tip side of engine lubrication oil-feed steel pipe in prior art, the tip side that is about to engine lubrication oil-feed steel pipe in prior art in the utility model is molded directly within to be taken in body, that is to say that this adapter body is the adapter body that forms the tip side of engine lubrication oil-feed steel pipe, so just avoided by taking over body, by mould, withholding on the tip side of engine lubrication oil-feed steel pipe as in prior art, thereby avoided making to take over body by the mode of withholding and produced the defect of leaking, effective guarantee sealability.
Accompanying drawing explanation
Fig. 1 is the structural representation that engine lubrication oil-feed steel pipe of the present utility model is connected with engine lubrication oil-feed steel pipe with adapter assembly.
Fig. 2 is the structural representation of adapter assembly for engine lubrication oil-feed steel pipe of the present utility model.
As shown in the figure: 1, take over body, 1.1, sealing ring surface, 1.2, connect ring wall, 1.3, upper hole, 2, engine lubrication oil-feed steel pipe, 3, inner tube, 3.1, endoporus.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, engine lubrication oil-feed steel pipe adapter assembly of the present utility model, comprises and takes over body 1, forms sealing ring surface 1.1 and be connected ring wall 1.2 on the outer wall of described adapter body 1.
Unlike the prior art, the upper end of described adapter body 1 is provided with the upper hole 1.3 being equipped with mutually with engine lubrication oil-feed steel pipe 2 external diameter sizes.In the middle and lower part of described adapter body 1, be also provided with the inner tube 3 that endoporus 3.1 internal diameters are less than hole 1.3 internal diameters, described inner tube 3 is integral type structure with taking over body 1, and endoporus 3.1 and the upper hole 1.3 of described inner tube 3 coaxially arrange.Wherein inner tube 3 is integrated for integral type structure refers to both with taking over body 1, is an overall structure.
As shown in Figure 2, one end of engine lubrication oil-feed steel pipe is set with adapter body 1 of the present utility model, the other end of engine lubrication oil-feed steel pipe is provided with the connecting end with ring, by this connecting end with ring, can make sebific duct firmly be connected with engine lubrication oil-feed steel pipe.
