Description

Technical Field

[0001] The utility model relates to the technical field of basic parts and components, in particular to a novel locking nut. Background Art

[0002] Bolts and nuts are usually used in combination and are widely used in modern facility construction and equipment assembly. They are one of the main ways to connect and reinforce two objects in modern production and life. When the threaded surface of the connection position of the two objects to be connected is long enough, bolts and screws can usually be used alone for connection. However, when the threaded surface of the connection position of the two objects is short, or even lacks threads, the bolts need to be matched with nuts to provide threaded surfaces for installation and reinforcement. When the threaded surface is short, nuts can also increase the area of ​​the threaded connection, lock the bolts, and strengthen the strength of the installation structure. Therefore, nuts and bolts are also one of the most important basic components in modern times.

[0003] The existing locking nuts are basically hexagonal or circular cylinders, most of which are not thick enough and the force-bearing area of ​​the nuts is insufficient, which makes it very inconvenient to rotate and install the nuts. In addition, the existing nuts are basically used for a single purpose and lack further auxiliary locking structures. The threaded connection area with the bolts is still insufficient and is prone to loosening.

[0004] In order to solve the above problems, we have made improvements and proposed a new type of locking nut. Utility Model Content

[0007] As a preferred technical solution of the utility model, an extension ring is fixedly welded on the bottom edge of the nut, the outer surface of the extension ring is flush with the nut, and the first anti-slip pattern extends from the outer surface of the nut to the surface of the extension ring.

The top and bottom ends of the inner wall of the nut attached tube are fixedly provided with connecting plates, and the connecting plates are annular. The top and bottom of the outer wall of the threaded tube are respectively fixedly connected to the two connecting plates.

[0010] As a preferred technical solution of the utility model, the tops of the four locking plates are fixedly connected to the bottom surface of the connecting plate at the bottom end of the nut attached tube, and the four locking plates are arranged around the threaded tube at equal intervals.

[0011] As a preferred technical solution of the utility model, the four locking plates are all arc-shaped, and the top of their outer surfaces are provided with external locking threads, which extend from the top of the locking plates to the middle of the locking plates, and the bottom of the inner surfaces of the four locking plates are fixed with hooks.

[0012] As an optimal technical solution of the utility model, an internal locking thread is provided on the top of the inner wall of the locking tube, and the inside of the locking tube is threadedly connected to the locking plate through the internal locking thread and the external locking thread.
