Abstract
A threaded connection structure for rotatably connecting and disconnecting adjoining members including a female member having annular internal pitched threads and a male member for threading into the female member having outer threads complemental to the threads of the female member with raised areas along the axial faces of the threads of one of said members to cause areas of concentration of unit pressure between the threads so that unwanted rotation and unwanted unthreading is prevented. A flange is provided on one member to engage a shoulder on the other member for continued axial surface pressure of the raised areas.
Claims11
A threaded connection structure for rotatably connecting and disconnecting adjoining members comprising in combination:
- an outer female member having annular inner internal pitched threads;
- an inner round male member having circular pitched threads complemental to the threads of the female member for being rotatably threaded into the female member with said threads of one member engaging the threads of the other member along axially facing thread surfaces;
- raised areas on axial face of the threads of one of the members causing a concentration of unit pressure at the location where the raised area engages a face of the thread of the other member so that unwanted rotation and unthreading is prevented;
- and wherein upon axial stress between the members the threads of the members are in engagement only in the area of said raised areas.
