Description

Technical Field

[0001] The utility model relates to the field of mechanical manufacturing and engineering, and specifically discloses a copper nut equipped with a self-locking structure. Background Art

[0002] As a kind of fastener, copper nuts are widely used in various fields such as machinery manufacturing, electrical equipment, and construction engineering. Since copper has excellent electrical conductivity and corrosion resistance, copper nuts are particularly important in electrical connections and corrosion-resistant applications. However, with the continuous improvement of modern industry's requirements for fastener performance, traditional copper nuts have exposed some shortcomings in practical applications, especially in terms of corrosion resistance, anti-loosening and anti-vibration. There is room for improvement. The existing anti-loosening nut structure (publication number: CN216691817U) has at least the following disadvantages:

[0003] 1. Existing copper nuts are prone to corrosion when exposed to high humidity, acid, alkali or other corrosive environments, resulting in thread wear and loose connections. This not only shortens the service life of the nut, but also increases the frequency of maintenance and replacement, so an anti-corrosion device is urgently needed.

[0004] 2. Existing copper nuts rely on the friction between threads for locking, but in a vibration or impact environment, the nut is easy to loosen and cannot ensure a long-term stable tightening state. This is particularly obvious in high-vibration equipment and key connection parts, affecting the safety and reliability of the equipment, so a locking device is urgently needed.

[0005] 3. Existing copper nuts lack a special anti-vibration design. Traditional nuts perform poorly in high-vibration environments and are prone to displacement and loosening. When the nut and bolt connection part is subjected to vibration impact, it cannot effectively absorb and disperse the vibration energy, resulting in a decrease in the fastening effect. Therefore, a device that can reduce vibration is urgently needed. Utility Model Content

[0022] Example

[0023] See also Figure 1 , the utility model provides a technical solution:

[0024] A copper nut equipped with a self-locking structure comprises a copper nut body, the copper nut body is provided with a threaded hole, the copper nut body is internally connected to a bolt, the outside of the copper nut body is covered with a sleeve, a bayonet support frame is installed on the side of the copper nut body, a nut is installed in front of the copper nut body, an anti-vibration gasket is installed between the nut and the copper nut body, the sleeve and the copper nut body are integrated in design, the bayonet support frame is snap-on design, the surface of the anti-vibration gasket has an anti-slip design, the nut and the bolt are matched with a serrated thread, and the surface of the copper nut body has an anti-slip design.

[0025] In this embodiment, the sleeve can effectively isolate the copper nut body from direct contact with the external environment, especially in high humidity, acidic and alkaline or other corrosive environments, significantly reducing the corrosion risk of the copper nut body. Through laboratory testing, in a simulated salt spray test, the copper nut equipped with an anti-corrosion sleeve had no obvious signs of corrosion on the surface after being continuously exposed to a salt spray environment for 240 hours. Under the same conditions, traditional copper nuts that are not equipped with sleeves showed obvious corrosion spots and thread wear within only 72 hours. This result shows that the anti-corrosion sleeve can significantly extend the service life of the nut and reduce the frequent replacement and maintenance costs caused by corrosion.

[0026] The snap-on support frame design of the utility model provides additional mechanical locking force, so that after the nut is tightened on the bolt, it can be firmly fixed in place and will not loosen even under vibration and impact conditions. Through the vibration table test, in a vibration environment with a simulated frequency of 50Hz and an acceleration of 5g, the copper nut equipped with the snap-on support frame remained stable during the continuous vibration test and did not loosen. Under the same conditions, the traditional nut began to loosen after 30 minutes of testing, and the loosening amount reached 20% of the initial tightening force. This experimental data shows that the snap-on support frame can significantly improve the anti-loosening performance of the nut and ensure the operating stability of the equipment in a high-vibration environment.

[0027] The anti-vibration gasket of the utility model can effectively absorb and disperse the energy of mechanical vibration, reduce the impact of vibration on the connection parts of nuts and bolts, and thus prevent the nuts from loosening. In actual application tests, the vibration frequency generated by the equipment during operation is 100Hz. The thread gap of the nuts not equipped with anti-vibration gaskets increased by 0.1mm after 24 hours, while the thread gap of the nuts equipped with anti-vibration gaskets remained stable under the same conditions without obvious changes. In addition, the anti-vibration gasket can also effectively reduce the noise level of the equipment during operation. Tests show that the noise is reduced by about 5dB. This shows that the anti-vibration gasket can not only improve the tightening effect of the nut, but also improve the overall operating environment of the equipment.

[0028] It should be noted that the following is a comparison table of experimental data between the utility model and the traditional equipment:
