Problems solved by technology
[0003] In order to overcome the shortcomings of the existing threaded fasteners equipped with spring washers in the harsh environment of vibration and shock for a long time, it is impossible to overcome the shortcomings of the spring washers on them, such as scatter, separation, and falling off after the spring washers are broken, a special structure is proposed. Convenient, according to the specific needs of spring washers of different specifications, a geometric groove with reasonable depth and geometric shape that can protect the spring washer can be provided on the pressing end surface (even if the spring washer is broken and scattered) condition, this groove can also ensure that the broken body on the spring washer is protected from accidents caused by the broken body on the spring washer and the threaded fastener falling off) on a pressing end surface A new nut with grooves is provided to make up for the current deficiency

Embodiment Construction
[0023] Please refer to Figure 1 to Figure 6 . Firstly, according to the required specification, shape, size and appearance design, the pressing end surface (6) is processed with a geometric groove (7) and the screw hole (15) is provided with an internal The new nut (1) of the thread (8); according to the requirements, the bolt (2) and the spring washer (3) that are provided with the positioning boss (12) on the bolt head (11) matched with the new nut (1) are selected spare. When in use, first pass the threaded end (9) on the bolt (2) matching the new nut (1) through the matching holes ( 13), and then put the spring washer (3) into the circular geometric groove (7) provided on the pressing end surface (6) of the new nut (1), and then put the matched spring washer (3) ) of the new-type nut (1) press-fitting end surface (6) is sleeved in place and screwed into the threaded end (9) on the bolt (2), and finally the new-type nut (1) is tightened and installed when it is in place...

The invention provides a novel nut provided with a groove on a pressing fit end surface, is suitable for long-time positioning in an bad environment with shock and impact, and can be applied to engineering machinery, railway locomotives, harbor machinery, bridge engineering and textile machinery. The pressing fit end surface of the novel nut is provided with at least one geometric groove matched with a spring washer. The novel nut has the advantages of strong adaptability, simple structure, convenience for use, low cost, standardization, interchangeability, universality and ideal impact and shock resistance, and can prevent accidents caused by scattering, separation and fall of the spring washer after the rupture.
Description
technical field [0001] The invention relates to a novel nut with grooves on the pressing end surface, which is suitable for long-term harsh environment of vibration and impact, and can be applied to engineering machinery, railway locomotives, port machinery, bridge engineering, textile machinery and the like. Background technique [0002] In order to solve the anti-vibration and anti-loosening of threaded fasteners, the commonly used solutions are to use spring washers, nylon embedding, pins, deformed threads, super glue bonding and other methods, although they can delay the threaded fasteners to a certain extent. It takes time to loosen and fall off by itself, but it cannot fundamentally solve the problem, especially the spring washer, which has the widest range of use, the largest amount of use, and better anti-vibration effect. Accidents caused by loose separation and falling off after breaking, so it is unsatisfactory in practice. Contents of the invention [0003] In...
