[0008] Preferably, a first threaded hole is formed on the inner side of the first nut body.
[0009] Preferably, the connecting columns are distributed in two groups, and the connecting columns are symmetrical about the central axis of the first nut body.
[0010] Preferably, a second threaded hole is formed on the inner side of the second nut body.
[0011] Preferably, the central axis of the second threaded hole coincides with the central axis of the first threaded hole, and the structure of the first threaded hole is consistent with the structure of the second threaded hole.
[0012] Preferably, the contact piece forms a sliding structure through a sliding column, a sliding groove and a connecting column, and the thickness of one end of the contact piece is 1 mm.
[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0014] 1. In the present invention, by arranging the nut body, the connecting column, the abutment piece, etc., the first nut body completes the connection work with the screw rod through the combination of the connecting column and the second nut body, and when people rotate the bolt so that it extends into the connecting column, the abutment piece is pushed, and the abutment piece can be inclined to abut against the outer wall of the screw rod, further enhancing the torque between the nut and the screw rod at this location, thereby improving the anti-loosening performance of the fastening nut and preventing the nut from loosening.

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] Reference Figure 1-3, a kind of anti-loosening fastening nut, comprising a first nut body 1, the bottom end of the first nut body 1 is connected to a connecting column 3, and the bottom of the connecting column 3 is welded with a second nut body 4, one side of the connecting column 3 is threadedly connected to a bolt 6, and the other side of the connecting column 3 is plugged with an abutment piece 7, the outer wall of the connecting column 3 close to the abutment piece 7 is provided with a reserved bin 9, and the inner wall of the reserved bin 9 is provided with a slide groove 10, the outer wall of the abutment piece 7 is fixed with a sliding column 8, and the sliding column 8 and the slide groove 10 are slidingly arranged, the connecting columns 3 are distributed in two groups, and the connecting columns 3 are symmetrical about the central axis of the first nut body 1, and by providing four symmetrically distributed connecting columns 3, it is multi- The abutment pieces 7 in different directions provide positions, which facilitate the abutment pieces 7 to abut from multiple positions, thereby improving the connection performance between the nut and the screw. The abutment piece 7 forms a sliding structure with the connecting column 3 through the sliding column 8 and the sliding groove 10, and the thickness of one end of the abutment piece 7 is 1 mm. The bolt 6 is manually rotated so that it pushes one end of the abutment piece 7. Then, the abutment piece 7 moves along the sliding groove 10, which is horizontal for a distance on the inside and inclined for another distance, through the sliding column 8. When the sliding column 8 moves into the inclined sliding groove 10, the abutment piece 7 can abut against the outer wall of the screw in an inclined shape, thereby effectively improving the connection performance between the nut and the screw.
[0022] A first threaded hole 2 is provided on the inner side of the first nut body 1, and the connection between the first nut body 1 and the screw is completed through the first threaded hole 2. A second threaded hole 5 is provided on the inner side of the second nut body 4, and the connection between the second nut body 4 and the screw is completed through the second threaded hole 5. The central axis of the second threaded hole 5 coincides with the central axis of the first threaded hole 2, and the structure of the first threaded hole 2 is consistent with that of the second threaded hole 5. Through the distribution of the first threaded hole 2 and the second threaded hole 5, it can be smoothly threadedly connected to the screw.
[0023] Working principle: When in use, the staff first connects the screw and the nut. The screw is first connected to the first threaded hole 2 at the first nut body 1, and then continues to move, and then connected to the second threaded hole 5 at the second nut body 4. Then, people will turn the bolt 6 so that it pushes one end of the abutment piece 7, and the abutment piece 7 moves along the slide groove 10 with a horizontal distance on the inner side and an inclined distance on the other side through the slide column 8. When the slide column 8 moves into the inclined slide groove 10, the abutment piece 7 can be inclined to abut the outer wall of the screw, so that the force between the middle part of the nut and the screw is large, and the abutment piece 7 is in reverse abutment, which effectively improves the connection performance between the nut and the screw.
