Problems solved by technology

[0002] Ordinary nuts have relatively low assembly efficiency during use due to their structural limitations
When a large number of bolts are used in the fields of machinery, automobiles, aerospace, and engineering industries, especially in the working conditions of long threaded rods and corroded threaded rods, even if a pneumatic screwdriver is used, the worker's operation is still cumbersome and the efficiency is still relatively low. Meet the needs of large-scale, high-volume production and assembly

Embodiment Construction

[0026] Such as Figure 1-7 As shown, the split nut: includes the left half nut 1 and the right half nut 2 made of stainless steel by turning and milling. The top surface of the left half nut 1 is provided with an identification process hole 10, the left half nut 1 and the right half nut 2 The thread start position of the inner wall differs by half a pitch. The corresponding ends of the left half nut 1 and the right half nut 2 are the matching bosses and notches, namely: the front end of the left half nut 1 is the first upper boss 3 and The first lower notch 4, the rear end is the first upper notch 5 and the first lower boss 6, correspondingly, the front end of the right half nut 2 is the second upper notch and the second lower boss, and the rear end is the second upper boss And the second lower notch; and, the bottom surface of the first upper boss 3 is a first arc-shaped curved surface 7 and is provided with a first locking block 8, and the top surface of the first lower boss 6...

Abstract

The invention belongs to the technical field of nuts, and particularly discloses a split nut. The split nut comprises a left half nut and a right half nut. The half screw pitch difference exists between the starting positions of threads of the inner walls of the left half nut and the right half nut. The two corresponding ends of the left half nut and the right half nut are provided with bosses andnotches, wherein the bosses and the notches are matched, namely, one end of the left half nut is provided with the upper boss and the lower notch, the end, corresponding to the end of the left half nut, of the right half nut is provided with the upper notch and the lower boss, the other end of the left half nut is provided with the upper notch and the lower boss, the end, corresponding to the endof the left half nut, of the right half nut is provided with the upper boss and the lower notch, and the bottom surface of the upper boss and the top surface of the lower boss of the two corresponding ends of the left half nut and the right half nut are matched arc-shaped curved surfaces. According to the split nut, due to design of the arc-shaped curved surfaces, the left half nut and the righthalf nut can conduct one-way moving combination along the arc-shaped curved surfaces, after the left half nut and the right half nut are fastened tightly, the two half nuts are blocked in two ways andtightly clamped together, and the fastening function is quickly implemented.

Description

Technical field [0001] The invention belongs to the technical field of nuts, and particularly relates to a split nut. Background technique [0002] Due to the structural limitation of ordinary nuts, the assembly efficiency is relatively low during use. When bolt assembly is widely used in machinery, automobile, aerospace, and engineering industries, especially under working conditions such as long threaded rods and corroded threaded rods, even if pneumatic screwdrivers are used, workers’ operations are still cumbersome and the efficiency is still relatively low. Meet the needs of large-scale, mass production and assembly. Summary of the invention [0003] In view of the problems existing in the prior art, the purpose of the present invention is to provide a split nut that can quickly perform the tightening action. [0004] In order to achieve the above objectives, the technical solutions adopted by the present invention are as follows: [0005] Split nut: Including the left half nu...
