Abstract
An outer body of a nut defines an axial port and carries initial guide means. An inner body, movably accepted in the port in the axial direction, is divided into at least two jaws in the axial direction, which carry respectively an internal thread segment on their inner radial area. The jaws also include second guide means which interact with the first guide means in such a way that the jaws, when the outer body is moved relative to the inner body in a loosening direction, are moved radially outwards, and if the outer body is moved relative to the inner body in a tightening direction, are moved radially inwards. As the jaws can be moved when movement is in the radial direction, their internal thread segments can be brought smoothly into engagement with the outer thread of a threaded rod.
Claims7
A nut comprising:
- an outer body which has an axial port;
- and inner body, which is movably accepted in the port in an axial direction, has an axial internal thread and is divided into at least two jaws in an axial direction, which jaws bear an internal thread segment on their radially inner surface and which, when the outer body is moved relative to the inner body in the loosening direction of the nut are moved apart;
- initial guide means provided on the outer body;
- and
- second guide means provided on the jaws and interact with the initial guide means such that the jaws are closed, when the outer body is moved relative to the inner body in the loosening direction of the nut, characterized in that:
- the second guide means interact with the initial guide means such that the jaws when the outer body is moved relative to the inner body in the loosening direction, are pushed radially outwards and, when the outer body is moved in the tightening direction relative to the inner body, are pushed radially inwards.
