A chute 22 is opened on one side of the placement block 21. A sliding block 23 is slidably connected inside the chute 22 on the surface of the placement block 21. An anti-loosening mechanism is fixedly connected to one side of the sliding block 23. The anti-loosening mechanism is an anti-loosening plate 24. A blocking block 25 is inserted inside the chute 22 on the surface of the placement block 21. When using the track fastening assembly, the elastic strip 5 is placed on the track, and then the bolt 1 passes through the gasket 4. Then, the bolt 1 driving the gasket 4 will pass through the elastic strip 5 and be threadedly fixed to the foundation. At this time, the gasket 4 and the elastic strip 5 are squeezed and fixed to abut and fix the elastic strip 5 to the track to complete the fastening of the track. When the bolt 1 abuts and fixes the elastic strip 5 through the gasket 4, the placement block 21 on the elastic strip 5 will also be fixed in position. Then, the sliding block 23 can be moved so that the sliding block 23 moves inside the chute 22 on the surface of the placement block 21. Then, the sliding block 23 drives the anti-loosening plate 24 to reach the nut of the bolt 1. Then, the blocking block 25 is moved so that the blocking block 25 reaches inside the chute 22 to fix the position of the sliding block 23. Then, the anti-loosening plate 24 is fixed to the nut of the bolt 1 to prevent the bolt 1 from reversing during vibration, resulting in loosening. By using the anti-loosening device 2, the bolt 1 can be restricted to prevent the bolt 1 from reversing and loosening during vibration, thereby improving the use effect of the fastening assembly.
[0030] Referring to Figures 1-4 As shown in the figure, this embodiment discloses that the anti-loosening plate 24 is V-shaped, and the size of the anti-loosening plate 24 is adapted to the size of the nut of the bolt 1. By using the anti-loosening plate 24 with a suitable size, the position of the bolt 1 can be better restricted, thereby improving the use effect of the anti-loosening plate 24. A reinforcing rod 26 is fixedly connected inside the chute 22 on the surface of the placement block 21, and the reinforcing rod 26 is slidably connected to the sliding block 23. By using the reinforcing rod 26, the connection strength between the sliding block 23 and the placement block 21 is improved, and the situation where the sliding block 23 is separated from the placement block 21 is avoided. A number of anti-sliding blocks 27 are fixedly connected to both sides of the sliding block 23, and the number of anti-sliding blocks 27 is arranged at equal intervals on both sides of the sliding block 23. By using the anti-sliding blocks 27, the friction between the sliding block 23 and the operator is increased, thereby improving the use effect of the sliding block 23. A support plate 28 is fixedly connected to one side of the sliding block 23, and the side of the support plate 28 away from the sliding block 23 is fixedly connected to the anti-loosening plate 24. By using the support plate 28, the connection between the sliding block 23 and the anti-loosening plate 24 is supported to prevent the connection between the sliding block 23 and the anti-loosening plate 24 from deforming under force.
[0031] Referring to Figures 1-4As shown in the figure, in this embodiment, an auxiliary device 3 for fixing the blocking block 25 is provided on one side of the placing block 21 close to the blocking block 25.

A control block 35 is fixedly connected to one side of the pressing plate 33, and the control block 35 is inclined on one side of the pressing plate 33. By using the control block 35, the contact area between the pressing plate 33 and the operator is increased, making it easier for the operator to move the pressing plate 33.
[0033] Working principle: When using the track fastening assembly, the elastic strip 5 is placed on the track, and then the bolt 1 passes through the gasket 4. Then, the bolt 1 driving the gasket 4 will pass through the elastic strip 5 and be threadedly fixed to the foundation. At this time, the gasket 4 and the elastic strip 5 are squeezed and fixed to abut and fix the elastic strip 5 to the track to complete the fastening of the track. When the bolt 1 abuts and fixes the elastic strip 5 through the gasket 4, the placing block 21 on the elastic strip 5 will also be fixed in position. Then, the sliding block 23 with the anti-sliding block 27 can be moved to make the sliding block 23 move inside the surface chute 22 of the placing block 21. Then, the sliding block 23 drives the anti-loosening plate 24 to reach the nut of the bolt 1. Then, the blocking block 25 is moved to make the blocking block 25 reach inside the chute 22 to fix the position of the sliding block 23. Then, the anti-loosening plate 24 is fixed to the nut of the bolt 1 to prevent the bolt 1 from reversing during vibration, resulting in loosening. By using the anti-loosening device 2, the bolt 1 can be restricted to prevent the bolt 1 from reversing and loosening during vibration, thereby improving the use effect of the fastening assembly.
[0034] When the blocking block 25 is placed inside the sliding groove 22 on the surface of the placing block 21, the pressing plate 33 can be moved first through the control block 35 to compress the spring 32, and the telescopic rod 34 will become shorter. Then, the blocking block 25 is placed inside the sliding groove 22, and then the pressing plate 33 is released. Then the spring 32 resets to squeeze and fix the blocking block 25. By using the auxiliary device 3, the position of the blocking block 25 can be fixed, so as to improve the use effect of the blocking block 25 and further improve the use effect of the anti-loosening device 2.
