Method and device for gripping a cable

摘要

A device for gripping a cable includes a device body, one or more gripping elements, and a gripping element housing configured to support the one or more gripping elements. The gripping element housing is rotatably coupled to the device body such that rotation of the gripping element housing relative to the device body about a longitudinal axis causes the one or more gripping elements to move radially relative to the longitudinal axis. The gripping elements may be configured such that they do not rotate relative to the gripping element housing. The gripping elements may also be configured such that they move only in a radial direction relative to the longitudinal axis, or alternatively such that they move both radially and longitudinally relative to the longitudinal axis.

1. A device for gripping a cable, comprising:
a device body; one or more gripping elements movably coupled to the device body; a gripping element housing configured to support the one or more gripping elements, the gripping element housing being rotatably coupled to the device body such that rotation of the gripping element housing relative to the device body about a longitudinal axis causes the one or more gripping elements to move radially relative to the longitudinal axis; and a locking ring disposed between the device body and the gripping element housing, wherein the locking ring rotatably couples to the device body, wherein the locking ring adjusts to a position that resists rotation of the gripping element housing relative to the device body, wherein the device body and the one or more gripping elements are coupled by a frictional self-locking connection such that when the one or more gripping elements are tightened in a first direction, the one or more gripping elements are restricted by frictional forces from releasing in an opposite direction, wherein the device body and the one or more gripping elements are coupled by a threaded connection defined by:
a threaded surface of the device body, the threaded surface of the device body defining a plane oriented perpendicular to the longitudinal axis; anda threaded surface of each gripping element,wherein the threaded surface of each gripping element is configured to interact with the threaded surface of the device body such that rotation of the gripping element housing relative to the device body about the longitudinal axis causes the threaded surface of each gripping elements to slide along the threaded surface of the device body, which causes each gripping element to move radially relative to the longitudinal axis.
