[0011] The following further describes the specific embodiments of the present utility model with reference to the accompanying drawings.
[0012] As Figure 1-2 shown, a locknut assembly includes a first connection end 1 and a second connection end 2. Internal threads are provided inside both the first connection end 1 and the second connection end 2. One end of the first connection end 1 is provided with a control part 3, and the control part 3 is used to control the rotation of the first connection end 1. It also includes an elastic part for connecting the first connection end 1 and the second connection end 2. The elastic part includes two side plates 4, and the two side plates 4 are respectively connected to the first connection end 1 and the second connection end 2. A plurality of arc-shaped elastic plates 5 are evenly arranged between the two side plates 4. The outer surface of the second connection end 2 is provided with a sleeve 6, and the sleeve 6 is rotatably connected to the second connection end 2. An external thread is provided on the outer surface of the first connection end 1, and an internal thread meshing with the external thread on the outer surface of the first connection end 1 is provided inside the sleeve 6.
[0013] The elastic plate 5 is generally V-shaped as a whole, and the protruding end of the elastic plate 5 faces the direction of the central axis of the side plate 4. When the elastic plate 5 is squeezed, the elastic plate 5 is completely located inside the sleeve 6.
[0014] Before using this nut, first, the internal thread end of the sleeve 6 is matched with the external thread on the first connection end 1. By continuously rotating the sleeve 6, the distance between the first connection end 1 and the second connection end 2 is continuously reduced, thereby realizing the extrusion of the elastic plate 5. After the elastic plate 5 is extruded to a certain extent, the sleeve 6 stops rotating. At this time, the elastic plate 5 has an elastic potential energy to restore its original state, thus completing the adjustment of the nut. When using this nut, both the first connection end 1 and the second connection end 2 are threadedly connected to the bolt. Rotate the control part 3 until one side thereof abuts against an external object. At this time, the nut cannot be screwed further on the bolt. Then stop rotating the control part 3. Next, rotate the sleeve 6 in the reverse direction to separate the sleeve 6 from the first connection end 1. After the sleeve 6 is separated from the first connection end 1, the connection between the first connection end 1 and the second connection end 2 changes from the connection of the sleeve 6 to the connection of the side plate 4 and the elastic plate 5. The elastic plate 5 can increase the friction between the first connection end 1 and the second connection end 2 and the bolt through its elastic potential energy, thereby improving the loosening resistance of this nut. And after the sleeve 6 is separated from the first connection end 1, the elastic plate 5 is still located inside the sleeve 6, so that the sleeve 6 can play a protective role for the elastic plate 5 to prevent sundries from entering between the two side plates 4.
[0015] Further, one end of the sleeve 6 is provided with a rubber ring 7. The rubber ring 7 is wrapped around the outer surface of the first connection end 1. The rubber ring 7 can be elastically wrapped around the first connection end 1, and even after the sleeve 6 is separated from the first connection end 1, the rubber ring 7 can still be wrapped around the first connection end 1. At the same time, the rubber ring 7 does not affect the normal function of the elastic plate 5. At the same time, the rubber ring 7 can improve the sealing performance between the sleeve 6 and the first connection end 1 to slow down the corrosion of the elastic plate 5.
[0016] Further, a compressible sealing ring 8 is arranged on the outer surface of the second connection end 2. The outer surface of the sealing ring 8 abuts against the inner surface of the sleeve 6. The cooperation of the sealing ring 8 and the rubber ring 7 can further improve the sealing performance between the sleeve 6 and the first connection end 1 and the second connection end 2, further slow down the corrosion rate of the elastic plate 5. At the same time, the sealing ring 8 can also increase the friction force with the sleeve 6 to prevent the sleeve 6 from coming off the second connection end 2.
[0017] This kind of locknut assembly can make the nut assembly have excellent anti-loosening performance through the arranged elastic plate 5, and the elastic plate 5 does not directly contact the bolt. The elastic plate 5 is only subjected to extrusion force, so the wear of the elastic plate 5 can be avoided, the reuse rate of the nut assembly can be improved, and the anti-loosening effect after reuse can be ensured, and the use effect is good.
