[0005] Preferably, a second sealing ring is fixedly connected to the top of the threaded connecting post, and a third sealing ring is fixedly connected to the bottom of the body.

[0006] Preferably, the inner and outer walls of the body, protective cover, and threaded connecting post are all hot-dip coated.

[0007] Preferably, the protective cover has a circular cross-section.

[0008] Beneficial effects

[0009] This utility model provides a rust-proof nut with a sealing ring. It has the following advantages: Through the cooperation of the body, protective cover, first sealing ring, threaded connecting post, second sealing ring, and third sealing ring, this rust-proof nut with a sealing ring can isolate and protect the connection between the bolt and the body during use. Even if the inner wall of the body is worn due to the bolt during use, it can effectively prevent external substances from corroding the body, thus improving safety in use.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0014] Most existing nuts rely solely on protective coatings for rust prevention during use. However, this method still results in rust when wear occurs due to the lack of additional protection, causing inconvenience for users. In view of this, the present invention provides a rust-proof nut with a sealing ring. Through the cooperation of the body, protective cover, first sealing ring, threaded connecting post, second sealing ring and third sealing ring, the connection between the bolt and the body can be isolated and protected during use. Even if the inner wall of the body is worn due to the bolt during use, it can effectively prevent external substances from corroding the body, thus improving the safety of use.

[0015] Example 1: By Figure 1 , 2As can be seen from points 3 and 4, a rust-proof nut with a sealing ring includes a body 1, a threaded connecting post 5 fixedly connected to the top of the body 1, threads being machined on the inner walls of both the body 1 and the threaded connecting post 5, a protective cover 2 being threadedly connected to the outer wall of the threaded connecting post 5, and a first sealing ring 3 fixedly connected to the bottom of the protective cover 2, with the bottom of the first sealing ring 3 and the top of the body 1 being interference-fitted. In the specific implementation process, it is worth noting that the materials of the first sealing ring 3, the second sealing ring 4 and the third sealing ring 6 can all be nylon. There are no restrictions on the specific materials. They can be selected according to the actual use. When in use, the first sealing ring 3, the second sealing ring 4 and the third sealing ring 6 deform to achieve sealing. The first sealing ring 3 can improve the sealing performance between the protective cover 2 and the body 1. Furthermore, a second sealing ring 4 is fixedly connected to the top of the threaded connecting column 5, and a third sealing ring 6 is fixedly connected to the bottom of the body 1. In the specific implementation process, it is worth noting that the second sealing ring 4 and the third sealing ring 6 can improve the sealing between the body 1 and the bolts and external connecting parts; Furthermore, the inner and outer walls of the main body 1, the protective cover 2, and the threaded connecting column 5 are all hot-dip coated. In the specific implementation process, it is worth noting that when immersing zinc, the components need to be pickled and solvent-assisted to remove surface oxides and oil stains beforehand. Then, the components are immersed in molten zinc at about 450 degrees Celsius. After the components are taken out of the zinc liquid, they are quickly centrifuged to remove excess zinc liquid and allowed to cool and solidify naturally in the air to form a coating. It should be noted that if the coating is thick, "post-plating tapping" must be performed to restore the thread tolerance; otherwise, assembly is not possible. Furthermore, the protective cover 2 has a circular cross-section; In the specific implementation process, it is worth noting that the circular protective cover 2 can reduce the stress point of the protective cover 2, thus avoiding the phenomenon of accidental loosening; Specifically, when using the rust-proof nut with a sealing ring, the worker places the body 1 on the outer wall of the external bolt during installation, and then twists the body 1 to install the body 1 and the external bolt. At this time, the second sealing ring 4 deforms, generating huge friction and radial pressure, thereby achieving the dual functions of sealing and locking (preventing vibration and loosening). At the same time, the third sealing ring 6 is flattened and tightly fits against the surface of the connector to form a reliable end face seal. Then, the protective cover 2 is installed on the outer wall of the threaded connecting post 5, which can then protect the connection between the external bolt and the body 1.

[0016] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
