[0010] The following is a specific embodiment of the utility model and further describes the technical scheme of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.

[0011] As Figure 1 shown, the anti-rust lubricating nut comprises a nut body 1, the inner wall of the nut body 1 is provided with a thread 2, the left and right sides of the nut body 1 are provided with oil inlets 3 for lubricating oil to flow in, the oil inlets 3 and the thread 2 of the nut body 1 are provided with lubricating oil channels 4, the left and right sides of the nut body 1 are provided with sealing structures 5 for sealing the oil inlets 3, the sealing structure 5 comprises a sealing part 6, a sliding rod 7 and a connecting spring 8, the nut body 1 is provided with a mounting groove 9 for mounting the sealing structure 5, one end of the sliding rod 7 is connected with the sealing part 6, the other end of the sliding rod 7 extends out of the mounting groove 9 and is connected with a pulling part 10, the connecting spring 8 is sleeved on the sliding rod 7, and the sealing part 6 moves left and right in the mounting groove 9 under the action of the connecting spring 8 to seal the oil inlets 3.

[0012] Further, when it is necessary to add lubricating oil to the thread 2, the pulling part 10 is pulled, the sealing part 6 is retracted in the mounting groove 9, the oil inlets 3 are in a flowing state, and the lubricating oil is added to the oil inlets 3 to flow along the lubricating oil channels 4 into the thread 2 body, when the lubricating oil is added, the pulling part 10 is loosened, the connecting spring 8 rebounds, the sealing part 6 partially extends out of the mounting groove 9 to seal the oil inlets 3, and air is prevented from entering the thread 2 to affect the fastening of the nut.

[0013] Further, the lubricating oil channels 4 are communicated with the oil inlets 3, and the lubricating oil channels 4 are provided in an inclined structure.

[0014] Further, one end of the connecting spring 8 is connected with the sealing part 6, and the other end of the connecting spring 8 is connected with the nut body 1.

[0015] The specific embodiments described in the present application are only illustrative of the spirit of the utility model. Those skilled in the art to which the utility model belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the utility model or exceed the range defined by the appended claims.

[0016] Although the terms nut body 1, thread 2, oil inlet 3, lubricating oil channel 4, sealing structure 5, sealing part 6, sliding rod 7, connecting spring 8, mounting groove 9, pulling part 10, etc. are used more in the text, the possibility of using other terms is not excluded. The use of these terms is only to facilitate the description and explanation of the essence of the utility model; any additional limitation by interpreting them is contrary to the spirit of the utility model.
