Abstract
The invention provides a connection structure of a cylinder cap cover and a connection tube, which relates to the manufacturing field of cylinder cap covers and has simple processing, high efficiency and high finished product yield. The connection structure comprises a cylinder cap cover, an interface of a connection tube of the cylinder cap cover and the connection tube. The connection structure is characterized in that the interface of the cylinder cap cover is an unthreaded hole with circular arcs at two sides and parallel edges at the other two sides, a tail part of an inner thread joint is in a step structure, the inner thread joint is provided with the circular arcs at two sides and the parallel edges at the other two sides, screw threads are arranged at a peripheral surface of a head of the inner thread joint, the head of the inner thread joint passes through the interface of the cylinder cap cover, the step structure of the tail part of the inner thread joint is tightly adhered to an inner side face of the cylinder cap cover, the front end of a joint of the connection tube is installed on an end face of the tail part of the inner thread joint, an outer thread joint is sleeved on the joint of the connection tube, internal screw threads of the outer thread joint are connected to the head of the inner thread joint, and the end face of the tail part of the outer thread joint is tightly adhered to the outer side face of the cylinder cap cover.
Description
Technical field
The present invention relates to the manufacturing field of valve mechanism cover, be specially the linkage structure 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 tapped hole, the making of its tapped hole need to be used extra embedded part or external machining, its processed complex, machining period is long, efficient is low, and the aperture ratio of this tapped hole is larger, in case process a little deviation, can cause whole valve mechanism cover is waste product, causes its yield rate low.
Summary of the invention
For the problems referred to above, the invention provides the linkage structure of valve mechanism cover and adapter, its processing is simple, efficient is high, and so that yield rate is high.
The linkage structure 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, interior Threaded Connector Coupling afterbody is hierarchic structure, described interior Threaded Connector Coupling both sides circular arc, both sides parallel edges in addition, the external edge of head face of described interior Threaded Connector Coupling has screw thread, the head of described interior Threaded Connector Coupling 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 interior Threaded Connector Coupling, nipple is set in the joint of described adapter, described nipple internal thread connects the head of described interior Threaded Connector Coupling, 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 interior Threaded Connector Coupling 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 invention, 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 no longer needs to use extra embedded part or external machining all by casting straight forming, processing is simple, efficient is high, in addition, because casting, therefore its yield rate is high.
