Description

Technical Field

[0001] The utility model relates to the technical field of connecting pieces, in particular to an anti-loosening connecting piece. Background Art

[0002] At present, many devices are used in high-frequency vibration environments. Long-term vibration will inevitably cause the fixing bolts to vibrate, which will bring hidden dangers to the use of the equipment. At present, bolts with elastic washers are often used to prevent vibration, but in high-frequency vibration environments, they often become loose, resulting in unreliable use.

[0003] After searching, Chinese patent number CN205744835U discloses an anti-loosening connector, which solves the problem that the current anti-loosening bolts are prone to loosening. It includes a bolt, a polygonal tooth pad, an elastic washer and a polygonal nut. The lower surface of the bolt head of the bolt has an annular tooth that falls to one side, and the upper surface of the polygonal tooth pad has an annular tooth that matches the lower surface of the bolt head. When working, the upper surface of the polygonal tooth pad matches the annular teeth on the lower surface of the bolt head. The polygonal tooth pad and the elastic washer are installed in a polygonal groove with the same number of sides as the polygonal tooth pad opened on the upper surface of the connected part. A polygonal groove is also opened on the lower surface of the connected part. The polygonal nut is fixed by bolts in a polygonal groove with the same number of sides as the polygonal nut opened on the lower surface of the connected part. When working, the upper surface of the polygonal tooth pad is higher than the upper surface of the connected part, and the height is equal to the elastic deformation distance of the elastic washer. The utility model has a simple structure, reliable connection and good anti-loosening performance

As a result, the connection will shake violently to one side over time, thereby reducing the stability of the connection template installation. At the same time, it cannot be properly adjusted according to the actual thickness of the connecting device, thereby reducing the safety of the device. Utility Model Content
