Embodiment
[0022] A split-half lock nut of the present invention, such as figure 1 , 2 As shown, it includes a split nut 1, a locking slider 2, a locking rod 3, a split spring 4, an axial spring 5, a nut body 6 and a nut cover 7;
[0023] The split nut 1 is a two-half-ring split structure formed by axially cutting a circular truncated cone-shaped fitting with a threaded hole in the center. The two half-ring splits are symmetrically opened with spring mounting grooves at the junction, and the split nut 1 The internal thread of the threaded hole in the center of the fitting matches the external thread of the stud to be connected;
[0024] Split nut 1 The junction of the two half-ring sub-parts is matched by the stepped surface extending axially, which plays a guiding role when the two half-ring sub-parts are held tightly;
[0025] The center of the locking slider 2 is provided with a truncated cone-shaped through hole matching the shape of the split nut 1 assembly. The outer wall of the locking s...

The invention relates to a split-half locking nut, and belongs to the field of fasteners. The split-half type locking nut comprises a split-half nut, a locking sliding block, a locking rod, a split-half spring, an axial spring, a nut body and a nut sealing cover, wherein the split-half nut is of a structure comprising two semicircular split parts which are formed by axially cutting a circular table shaped assembly, and a threaded hole is formed in the center of the circular table shaped assembly; the locking sliding block sleeves a split-half nut assembly through a circular table shaped inner hole and is inserted into an inner chamber of the nut body; the upper end of the nut body passes through the nut sealing cover to enable axial limiting of the split-half nut. Before the nut is screwed, the locking rod is rotated to drive the locking sliding block to move upwards through the axial spring, and the two semicircular split parts are outwards sprung away through the split-half spring, thus the split-half locking nut can directly slide to the part to be screwed of a stud; then the locking rod is rotated to downwards press to drive the locking sliding block to downwards move; the two split parts of the split-half nut are extruded to inwards combine and compress the split-half spring by the locking sliding block through tapered surfaces; the enclasped split-half nut can be quickly locked to the stud to be connected.
Description
Technical field [0001] The invention relates to a split-half locking nut, which belongs to the field of fasteners. Background technique [0002] When the nut is tightened to the stud, there will inevitably be an empty stroke. That is, when the nut does not reach the final tightening position, the nut needs to be twisted on the non-locking (working) part of the front end of the stud with hands or tools, so that the nut runs along the stud axis and reaches the position to be locked. . When the thread idling stroke at the front end of the stud is long or the thread pitch is small, the idling stroke before locking will waste a lot of time and cause a lot of personnel or tool occupation. Summary of the invention [0003] The purpose of the present invention is to provide a split-half lock nut to solve the problem that the traditional nut must travel a certain stroke before being locked with the stud. [0004] The purpose of the present invention is achieved through the following techn...
