[0002] In the patent application with application announcement number CN218063031U, it includes a nut body, a center hole located in the center of the nut body, and a first internal thread located on the inner wall of the center hole. The first internal thread itself forms a spiral screw groove. The outer wall of the nut body is provided with a plurality of oil storage holes evenly distributed around the circumference. The oil storage holes are connected to the middle of the screw groove through a coaxial sealing hole, and the inner end of the sealing hole is located at the bottom of the screw groove. The diameter of the oil storage hole is larger than the diameter of the sealing hole. A matching rubber plug is provided in the sealing hole. The advantages of the rust-proof nut using the structure of the utility model are as follows: the opening of the opening and closing hole and the screw groove are connected through the opening by rotating the transverse plug. At this time, the lubricating oil in the oil storage hole can enter the screw groove through the opening and directly lubricate the first internal thread in the center hole. The entire lubrication process does not require unscrewing the nut from the bolt, which reduces a lot of trouble and improves lubrication efficiency.

[0003] In the prior art including the above-mentioned patents, nuts and bolts will rust when exposed to water during use. After a long time, the connection between the bolt and the nut will be more corroded. The rust will reduce the load-bearing capacity of the bolt and affect its strength. The rust will form oxides on the thread surface, making the thread difficult to disassemble. Utility Model Content

[0004] The purpose of the utility model is to provide a nut with water-proof and rust-proof functions, so as to solve the problem in the above background technology that the nut rusts when it comes into contact with water and is difficult to disassemble after being fixed with a bolt.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a nut with water-proof and rust-proof functions, comprising a nut, wherein rubber sealing rings are provided at the threaded grooves on the front and back of the nut, and rubber clamps are fixedly connected to the outer ring of the rubber sealing ring. A clamping column is fixedly connected to one side of the rubber clamp, and a protrusion for clamping is provided on the clamping column. The front and back of the nut are provided with clamping grooves corresponding to the positions of the rubber clamps.

[0006] Furthermore, the rubber sealing ring is fixed to the rubber clamping block and the clamping column through the clamping groove, wherein the outer side of the four rubber clamping blocks on the front side is provided with a rubber pressure ring, and the inner wall of the rubber pressure ring is fixedly connected to the outer wall of the rubber clamping block.

[0007] Furthermore, the diameter of the rubber sealing ring is adapted to the diameter of the internal thread of the nut.

[0008] Furthermore, the diameter of the rubber pressure ring is larger than that of the rubber sealing ring and is tightly attached to the outer wall of the nut.

[0009] Furthermore, the inner thread of the nut is connected to a bolt, and the inner wall of the rubber pressure ring is tightly attached to the outside of the bolt head.

[0010] Compared with the prior art, the beneficial effects of the present invention are: the nut with water-proof and rust-proof functions is reasonable and has the following advantages:

[0011] (1) The utility model is provided with a rubber sealing ring, which can be clamped and fixed by cooperating with a clamping column and a clamping groove. When the bolt is rotated and screwed into the nut, the rubber sealing ring can be squeezed by the bolt to fit tightly with the inner wall, so that its internal space forms a good seal to achieve a water-proof effect. At the same time, a rubber pressure ring is also provided. The inner wall size of the rubber pressure ring is slightly smaller than the size of the bolt head. When the bolt is rotated and fixed in place, the bolt head squeezes the rubber pressure ring outward to form a seal for the connection between the bolt and the nut, and cooperates with the internal rubber sealing ring to achieve a double sealing function, which has a good water-proof and rust-proof function. Most existing nuts and bolts will rust when they come into contact with water during use. After a long time, the connection between the bolt and the nut will be more corroded. The rust will reduce the bearing capacity of the bolt and affect its strength. The rust will form oxides on the thread surface, making the thread difficult to disassemble. The utility model can effectively prevent water from entering the connection between the nut and the bolt, and prevent the occurrence of rust. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Example 1:

[0022] In this embodiment, a nut with water-proof and rust-proof functions includes a nut 2, and rubber sealing rings 7 are provided at the threaded grooves on the front and back of the nut 2. The outer ring of the rubber sealing ring 7 is fixedly connected with a rubber clamp 4. One side of the rubber clamp 4 is fixedly connected with a clamping column 5. The clamping column 5 is provided with a protrusion for clamping, and the front and back of the nut 2 are provided with a clamping groove 6 corresponding to the position of the rubber clamp 4.

[0023] In this embodiment, the rubber sealing ring 7 is fixed to the rubber clamping block 4 and the clamping column 5 through the clamping groove 6, wherein a rubber pressure ring 3 is provided on the outer side of the four rubber clamping blocks 4 on the front side, and the inner wall of the rubber pressure ring 3 is fixedly connected to the outer wall of the rubber clamping block 4.

[0024] In this embodiment, the diameter of the rubber sealing ring 7 is adapted to the diameter of the internal thread of the nut 2 .

[0025] In this embodiment, the diameter of the rubber pressure ring 3 is larger than that of the rubber sealing ring 7 and is tightly attached to the outer wall of the nut 2 .

[0026] In this embodiment, the internal thread of the nut 2 is connected to the bolt 1, and the inner wall of the rubber pressure ring 3 is tightly attached to the outside of the head of the bolt 1. The head of the bolt 1 squeezes the rubber pressure ring 3 outward to form a seal at the connection between the bolt 1 and the nut 2, and cooperates with the internal rubber sealing ring 7 to achieve a double sealing function, which has good water-proof and rust-proof functions.

[0027] Working principle: When in use, first align the clamping column 5 with the clamping groove 6 on the nut 2. After alignment, insert the rubber clamping block 4 and the clamping column 5 into the clamping groove 6 for clamping and fixing. At this time, the two rubber sealing rings 7 are respectively located in the internal thread edge grooves on the front and back of the nut 2. After fixing, rotate the bolt 1 into the nut 2 to fix it. When the bolt 1 rotates inward through the internal thread of the nut 2, the head of the bolt 1 will squeeze the rubber clamping block 4 and the rubber sealing ring 7 on the front to form a seal with the nut 2 and the inside of the bolt 1. At the same time, the rubber pressure ring 3 is squeezed outward by the head of the bolt 1, so that its connection reaches a sealed state, thereby achieving a better water-proof effect at the internal connection between the nut 2 and the bolt 1 to prevent internal rust.
