Embodiment
[0021] A kind of quick locking nut of the present invention, as figure 1 , 2 As shown, it includes half nut 1, compression spring 4, locking slider 2, nut body 3, nut cover 5, and shifting block 6;
[0022] The half-nut 1 is a two-half-ring sub-part structure formed by axially cutting a frustum-shaped assembly with a threaded hole in the center. The junction of the two semi-ring parts is symmetrically provided with a spring installation groove. The half-nut 1 The internal thread of the threaded hole in the center of the assembly matches the external thread of the stud to be connected;
[0023] The junction of the two semi-annular parts of the sub-half nut 1 is matched by an axially extending step surface, which plays a guiding role when the two semi-annular parts are tightly hugged;
[0024] The center of the locking slider 2 has a frustum-shaped through hole matching the shape of the half nut 1. The outer wall of the locking slider 2 is processed with external threads, and ...

The invention relates to a rapid locking nut, and belongs to the field of fasteners. The rapid locking nut comprises a halved nut, compression springs, a locking sliding block, a nut body, a nut gland and a shifting block, wherein the halved nut has two semi-ring-shaped separate part structures which are formed by cutting a truncated cone shaped combined part with a threaded hole in the center; the locking sliding block is connected to the outside of the halved nut combined part in a sleeving manner through a truncated cone shaped inner hole; the locking sliding block is screwed into a cavity of the nut body in a threaded manner; and the halved nut is limited at the upper end of the nut body in the axial direction by the nut gland. During tightening, the locking sliding block is adjusted to move upwards relative to the nut body, the two semi-ring-shaped separate parts of the halved nut pop up outwards under the effect of the compression springs, and the rapid locking nut directly slides to a to-be-tightened part of a double-screw bolt; and then the locking sliding block descends along the cavity of the nut body, a conical surface of the locking sliding block extrudes the two separate parts of the halved nut to be combined inwards and compress the springs, and therefore, the enclasped halved nut and the to-be-connected double-screw bolt are locked rapidly.
Description
technical field [0001] The invention relates to a fast locking nut, which belongs to the field of fasteners. Background technique [0002] When the nut is tightened on the stud, there will inevitably be a section of empty travel. That is, when the nut does not reach the final position to be tightened, the nut needs to be twisted on the non-locking (working) part of the front end of the stud by hand or tools, so that the nut runs along the axial direction of the stud and reaches the position to be locked . When the thread idling stroke at the front end of the stud is long or the pitch is small, the idling stroke before this section of locking will waste a lot of time, resulting in a huge occupancy of personnel or tools. Contents of the invention [0003] The purpose of the present invention is to provide a fast lock nut in order to solve the problem that the traditional nut must travel a certain stroke before being locked with the stud. [0004] The purpose of the presen...
