Embodiment

[0017] Example: such as figure 1 A simple anti-loosening nut is shown, which is provided with an inner conical cavity nut 1 and a matching boss nut 2 with an outer conical shape, and the conical part of the supporting nut is set as The matching spiral progressive locking structure, an open channel is provided at the boss portion of the outer conical nut 2, and the formed intermittent ring-shaped progressive locking structure enables the nut boss part to follow the The locking action of the cavity nut 1 is deformed to lock the bolt 3, or to form a discontinuous bite with the teeth of the bolt 3 to enhance the locking effect on the bolt 3; it is gradually tightened by double nuts and the set cone The structure is multi-uniformly stressed to ensure the reliability of the overall function, and the expected goal that the nuts will not be loosened without damaging the normal characteristics of the bolts 3 is achieved; furthermore, on the parts of the split and joint surfaces of the ...

Abstract

The invention discloses a simple and convenient locknut. The locknut comprises a concave cavity nut in an inner cone shape and a boss nut in an outer cone shape and matched with the concave cavity nut, conical parts of the matched nuts are provided with matched spiral progressive type locking structures, an opening type through groove is formed in a boss part of the outer cone-shaped nut, and by means of a formed intermittent annular progressive locking structure, the boss part of the nut can be deformed along with the locking action of the concave cavity nut to lock a bolt, or can lock tightly to form an intermittent engagement shape with teeth of the bolt to enhance the locking efficiency of the bolt. According to the locknut, the integral efficiency reliability is guaranteed by multipleuniform stress of the two nuts and the conical annular progressive locking structure, and the expected goal that that nut locks without looseness is achieved without impairing the normal characteristics of the bolt.

Description

technical field [0001] The invention relates to the fields that need to be prevented from loosening in commonly used bolts and nuts, in particular to a simple anti-loosening nut. Background technique [0002] At present, it is known that in people's daily life and work, the application of various bolts and nuts can be seen everywhere. They are the most commonly used and common solid parts in various equipment. Screws are also called industrial meters. Although it seems to be relatively small on the surface, its actual effect is by no means small, especially on some important occasions involving safety, including various high-tech objects, the reliability of bolts and nuts cannot be ignored. Loosening or falling may cause fatal damage to the equipment; how to reliably and effectively prevent bolts and nuts from loosening is a specific problem that we often need to face seriously. There are not too few ready-made products and existing technical solutions However, due to the l...
