Description

Technical Field

[0001] The utility model relates to the technical field of clip nuts, and more specifically to a spring clip anti-loosening nut. Background Art

[0002] The spring clip anti-loosening nut is a nut installed on an iron clip, also known as a clip nut. It is a connecting piece of special-shaped parts in the fields of aviation, aerospace, and automobiles. In daily life, this clip nut is often used to install the license plate of a motorcycle. For example, a clip nut with an anti-loosening structure is disclosed in the prior art announcement number (CN218953720U). When the anti-loosening structure is needed, first pull the round rod to pull the round rod out of the installation groove. At this time, the traction rope can pull the limit plate to prevent the limit plate from falling and losing as much as possible. Then the screw is passed through the clip body as the screw The nail contacts the nut body, and then the screw is rotated to tighten the license plate using the screw and the nut body. After tightening, slide the rod upward. The sliding of the rod will drive the cylindrical block to slide, and the cylindrical block can prevent the rod from being out of contact with the limit plate as much as possible. Then slide the round rod along the inner wall of the installation groove again. The sliding of the round rod will drive the L-shaped plate to slide, and the sliding of the L-shaped plate will drive the limit plate to slide along the upper surface of the screw. At this time, the limit plate reaches the position of limiting the screw, and tries to prevent the screw from moving, which will cause loosening between the screw and the nut body. After the rod is inserted into the inner wall of the hole.

[0003] When the above device is in use, an anti-loosening structure is provided to limit the position of the screw, thereby preventing the screw from moving and becoming loose, thereby increasing the firmness of the clip body when clamping the license plate and improving the tightening effect of the clip body. However, the vibration generated by the nut body during use affects its stability in use, causing the nut body to loosen and fall off, thereby affecting its installation stability. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a spring clip anti-loosening nut. The technical problem to be solved by the utility model is: how to increase the installation stability and anti-loosening effect of the spring clip anti-loosening nut.
