Nut

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.

Description

technical field [0001] The invention relates to a nut, which comprises: an outer body with an axial through hole; an inner body, the inner body can slide axially and is located in the through hole, and is divided into at least two sliders in the axial direction, They each have an internal thread segment on their radially inner surface. And, if the outer body slides in the loosening direction relative to the inner body, the two sliders slide radially outward. Background technique [0002] A known nut from DE 40 24 784 A1 is known as a "quick mounting nut". In this well-known nut there is an axial through-bore of the outer body, called the "external limb", a hexagonal inner hole with an anterior region having constant inner dimensions in the axial direction, and a There is a conical area of ​​coupling which approaches the shaft in the direction in which the nut is unscrewed. [0003] The flange of this well known nut, called the "inner nut part", has a respective front sect...

Problems solved by technology

[0008] The well-known nut pair has its disadvantages compared to other nuts, if the bolt is on the screw, the opening and closing of the slider is relatively difficult
