Description

Nut structure

The present invention relates to a nut structure, especially a nut structure that can be used when the anti-loose washer combined with the bolt is used, so as to ensure the anti-loose force and the nut structure that effectively prevents the bolt from loosening.

According to the combination of nuts and bolts, the bolts and bolts are generally applied to the combination of the objects, and the bolts are threaded through the objects, and the nuts are bolted to the bolts, and the nuts are tightened on the objects. When the nut is combined with the bolt, if it is subjected to external force such as vibration during use, the nut and the bolt are easily loosened, resulting in the device not functioning properly or even jeopardizing the safety of the operator.

Therefore, in order to prevent the nut and the bolt from loosening, the related art practitioners are all committed to the development of a nut structure with anti-loosening effect, as shown in the eighth figure, which is a conventional anti-loose nut (4). A ring-shaped retaining wall (411) is formed on the upper end of the nut body (41), and the ring-shaped retaining wall (411) is surrounded by a recessed groove (412), and an anti-slot (412) is disposed in the recessed groove (412). The washer (42) is provided with a through hole (421) at the center of the lock washer (42) to correspond to the screw hole (413) provided in the nut body (41). Thereby, when the bolt passes through the bolted object, it will be screwed along the screw hole (413) of the nut (4), and when the bolt (42) is secured, the bolt will be pushed through the lock washer. (42) The through hole (421), and the anti-loose washer (42) is deformed by the bolt, and a reaction force is generated to tighten the bolt to fix the combined state of the two.

However, the nut body (41) of the existing nut (4) provides a locking groove (412) provided by the lock washer (42), and the groove bottom and the groove wall are smooth surfaces, so when the nut (4) is After the bolt is locked, if the bolt rotation is loosened by an external force such as vibration, the lock washer (42) fixedly coupled with the bolt is also rotated by the bolt, and the nut body (41) is fitted with the groove (412). The bottom of the groove and the wall of the groove are smooth, so that the anti-loose washer (42) is easy to idling in the groove (413) of the nut body (41), and the torsion force for preventing the rotation of the bolt is lost, and The existing anti-loose nut (4) will still be loosened with the bolt in actual use.

The reason is that the creator has the above-mentioned shortcomings in view of the use of the existing nuts. It is the result of many years of manufacturing and design experience and knowledge in related fields, and through various ingenuity, research and creation of this creation.
