Problems solved by technology

But it is precisely in this kind of place that is more basic and more inconspicuous, the gap between our country and developed countries will be even wider.” This also makes it necessary for everyone to work hard to continuously enrich and improve some highly reliable and general-purpose products. Strong non-loosening nut technical solution; HardLock is a double-nut anti-loosening structure. In reality, it is often limited by the use of space, and a single nut also has anti-loosening requirements.

Embodiment 1

[0017] Embodiment 1: as figure 1 What is shown is a single structure of a ring-type locknut, which is provided with a frustum-shaped internal thread cavity on the nut, making it a cavity nut 1 as a whole, and built into the cavity of the cavity nut 1 Set the ring member 2 of the truncated cone-shaped internal and external thread that is matched with it. Here, the taper of the tapered thread is set to 3 degrees, and between the internal thread and the external thread of the ring member 2, a Based on the elimination of the eccentric value of the standard thread fit clearance, that is, this value is the specification size of the nut—the gap between the internal thread and the bolt 3, and the fit clearance between the frustum-shaped internal thread and the 2-cone external thread of the ring member is also taken into account. When the ring member 2 is screwed into the bolt together with the nut for locking, it can achieve the comprehensive structural effect of the eccentricity of t...

Embodiment 2

[0018] Embodiment 2: as figure 2 The structure shown is a slightly changed ring-type locknut, which is actually designed according to the standard size of the nut, and the structural characteristics of the concave cavity nut 1 in this embodiment and the embodiment 1 have not changed in any way , just put the annular member part in embodiment 1 on another nut, thereby forming the boss nut 2, in the specific implementation, the structure and function effect of the double nut is slightly different from that of embodiment 1, but each has its own advantages. The advantage is that the overall structure and efficacy are also worthy of recognition, and can be selected for different needs; if this embodiment is to enhance the actual effect, it is obvious that it can be designed as a non-standard product by increasing the size according to actual needs.

Abstract

The invention discloses a ring type anti-loosening nut. It sets a truncated cone-shaped internal thread concave cavity on the nut, and a truncated cone-shaped internal and external thread ring member is built in it. Between the internal thread and the external thread of the ring member, a thread matching based on the specification The eccentric value of the gap makes the annular member screw into the bolt together with the nut for locking, with the comprehensive effect of the original nut structure formed and preserved, the eccentricity of the annular member and the multiple characteristic structures of the tapered thread, to achieve Reliably guarantee the expected goal that the single structure nut will not loosen when it is locked; furthermore, the above-mentioned single structure nut is used in a superimposed manner, or the ring-shaped member part of the above-mentioned single nut is arranged on another nut to form a double-nut structure. Improve the overall anti-loosening effect. With the structural features of being reasonable, simple and easy to implement, the present invention achieves the practical and reliable effect that the nut will not loosen when it is locked.

Description

technical field [0001] The invention relates to the field where looseness needs to be prevented in commonly used bolts and nuts, in particular to a single-ring type locknut assembly. 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 t...
