Detailed Description

The essential features and advantages of the utility model will be further elucidated with reference to the examples, without however being limited to the embodiments listed.

As shown in fig. 1 to 6, a vehicle locknut assembly of the present embodiment includes a first locking member 1 and a second locking member 2, the first locking member 1 includes a main body 11 and an extension portion 12, the extension portion 12 is arc-shaped, one end of the extension portion 12 is connected with an end surface of the main body 11, and the other end is a free end. The plurality of extending parts 12 are arranged around the first screw hole 13 of the main body 11 at equal intervals, the extending parts 13 are provided with screw thread parts 131, the second locking piece 2 comprises a second screw hole 21 and a containing cavity 22, and the containing cavity 22 is arranged on the end face of the second locking piece 2 and communicated with the second screw hole 21. The housing chamber 22 has a circular cross section, the housing chamber 22 is provided corresponding to the extension 12, and the extension 12 is drawn inward when the extension 12 is housed in the housing chamber 22. In the above technical solution, when the object 10 needs to be fixed, the bolt 20 is inserted through the object 10, and then the first locking member 1 is screwed with the bolt 20, and is fixed on the bolt through the first screw hole 13. And the second locking piece 2 is screwed on the bolt 20 through the second screw hole 21, the second locking piece 2 approaches to the first locking piece 1, and the extension part 12 stretches into the accommodating cavity and is folded towards the screw direction of the bolt, so that the threaded part 131 of the extension part is matched with the screw. When the second locking member 2 is locked, the second locking member 2 abuts against the first locking member 1, so that the locking member is more stable. Through the technical scheme, the first locking piece 1 can be locked by the second locking piece 2 in the axial direction, and the first locking piece 1 is pressed by the second locking piece 2 in the radial direction through the extension part 12, so that the first locking piece 1 is firmly connected with a bolt.

In this embodiment, the extension 12 is obliquely arranged, and the inner wall of the accommodating cavity 22 abuts against the outer side surface of the extension 12, so that the second locking member 2 can push the extension 12 to approach inwards during locking. The cross section of the main body 11 is polygonal, and the cross section of the second locking member 2 is polygonal, so that the tool can conveniently rotate the first locking member and the second locking member. When the first locking member 1 and the second locking member 2 are assembled, the end face of the main body 11 abuts against the end face of the second locking member 2, so that the second locking member 2 can abut against the first locking member 1. The first screw hole 13 and the second screw hole 21 have the same inner diameter, so that the two locking members can be assembled with the same bolt.
