Rotating shaft structure

Abstract

The present invention discloses a rotating shaft structure, comprising a fixed part having a connecting portion whose one end extends to form an external sleeve, wherein the external sleeve is cut to form an shaft hole which is axially communicatable with an embedded groove along whose perpendicular direction which is cut to form a connecting groove; an hollow inner bushing which is partitioned at least by a cut groove into at least two clamping rings whose one end extends radially to form a frame plate and the other end forms a opening with the frame plate, wherein at least a connecting plate is protrudingly disposed on one side of the frame plate; and a moving part having a linking portion on one end and a shaft extending axially from the other end, such that when the inner bushing is socketingly connected within the external sleeve, the clamping rings, the frame plate, and the connecting plate are positioned in the shaft hole, the embedded groove, and the connecting groove, respectively to form a firm connection, and the shaft is embeddedly inserted in the clamping ring in a tight fit.

Claims

1. A rotating shaft structure, comprising: a fixed part having a connecting portion whose one end extends to form an external sleeve, wherein the external sleeve is cut to form an shaft hole which is axially communicatable with an embedded groove along whose perpendicular direction which is cut to form a connecting groove;an hollow inner bushing which is partitioned at least by a cut groove into at least two clamping rings whose one end extends radially to form a frame plate and the other end forms a opening with the frame plate, wherein at least a connecting plate is protrudingly disposed on one side of the frame plate; anda moving part having a linking portion on one end and a shaft extending axially from the other end;such that when the inner bushing is socketingly connected within the external sleeve, the clamping rings, the frame plate, and the connecting plate are positioned in the shaft hole, the embedded groove, and the connecting groove, respectively to form a firm connection, and the shaft is embeddedly inserted in the clamping ring in a tight fit.

2. The rotating shaft structure according to claim 1, wherein the connecting portion of the fixed part or the linking portion of the moving part is disposed with at least a connecting hole.

3. The rotating shaft structure according to claim 1, wherein the connecting portion of the fixed part or the linking portion of the moving part is a mill-face prism or a polyhedron

4. The rotating shaft structure according to claim 1, wherein the external wall of the external sleeve is cut to form a through hole and the inner bushing is cut to form a plate hole at the location corresponding to the connecting plate, such that a connecting device can be put through and fastened.

5. The rotating shaft structure according to claim 1, wherein the openings of the at least two clamping rings may face the same or opposite direction.

6. The rotating shaft structure according to claim 1, wherein the surface of the shaft is arranged with a curved oil groove.

7. The rotating shaft structure according to claim 1, wherein the front edge of the shaft is provided with a chamfered portion.

8. The rotating shaft structure according to claim 1, wherein two ends of one side of the frame plate are stamped to form two protruding connecting plates on the opposite side.
