Abstract
The utility model provides a connection structure of a cylinder head cover and a connecting pipe, and relates to the manufacture field of cylinder head covers. The connection structure has the advantages of simple process, high efficiency and high finished product ratio, comprises a cylinder head cover, a connecting pipe interface of the cylinder head cover and a connecting pipe, and is characterized in that an interface of the cylinder head cover is an unthreaded hole provided with two arc-shaped edges and two parallel edges; a tail part of an inner thread connector adopts a step structure; the inner thread connector has two arc-shaped edges and two parallel edges; screw threads are formed on outer edge surface at a head part of the inner thread connector; the head part of the inner thread connector penetrates the interface of the cylinder head cover; the step structure at the tail part of the inner thread connector is attached to an inner side surface of the cylinder head cover; a front end of a connector of the connecting pipe is propped against an end surface at the head part of the inner thread connector; the connector of the connecting pipe is sleeved with an outer thread connector; internal threads of an outer thread connector is connected with the head part of the inner thread connector; and an end surface at a tail part of the outer thread connector is attached to an outer side surface of the cylinder head cover.
Description
Technical field
The utility model relates to the manufacturing field of valve mechanism cover, is specially the linkage structure of a kind of valve mechanism cover and adapter.
Background technique
Existing cylinder cover cap is with being connected of adapter and is threaded, the adapter interface of cylinder cover cap is a tapped hole, the making of its tapped hole need be used extra embedded part or external machining, its processed complex, machining period is long, efficient is low, and the aperture of this tapped hole is bigger, in case process deviation a little, can cause the entire cylinder housing is waste product, causes its yield rate low.
Summary of the invention
At the problems referred to above, the utility model provides the linkage structure of a kind of valve mechanism cover and adapter, and its processing is simple, efficient is high, and makes the yield rate height.
The linkage structure of a kind of valve mechanism cover and adapter, its technological scheme is such: it comprises valve mechanism cover, valve mechanism cover is taken over interface, take over, it is characterized in that: described valve mechanism cover interface is the both sides circular arc, both sides parallel edges unthreaded hole in addition, internal thread joint afterbody is a hierarchic structure, described internal thread joint both sides circular arc, both sides parallel edges in addition, the external edge of head face of described internal thread joint has screw thread, the head of described internal thread joint passes described valve mechanism cover interface, the hierarchic structure of its afterbody is close to the inner side surface of described valve mechanism cover, the joint front end of described adapter is mounted on the head end of described internal thread joint, nipple is set in the joint of described adapter, described nipple internal thread connects the head of described internal thread joint, and the tail end face of described nipple is close to the outer side surface of described valve mechanism cover.
It is further characterized in that: between the joint front end of described adapter and the head end of described internal thread joint O type circle is installed, O type circle is installed between the tail end face of described nipple and the outer side surface of described valve mechanism cover.
After adopting structure of the present utility model, the both sides circular arc, in addition the step trough of the exterior edge face of the unthreaded hole of both sides parallel edges and unthreaded hole is all by casting straight forming, no longer need to use extra embedded part or external machining, processing is simple, efficient is high, in addition, because so casting is its yield rate height.
