Technical Field

[0001] The utility model relates to the technical field of self-sealing nuts, and particularly relates to a self-sealing nut. Background Art

[0002] Self-sealing nuts are usually used to connect valves and pipelines to ensure the stable connection and sealing of the valves. These nuts are usually affected by harsh environments such as high pressure and high temperature, so they need to have a certain degree of durability and reliability.

[0003] The existing self-sealing nuts have poor sealing effects, and dust or external particles may enter the connection, affecting the connection tightness. At the same time, after installation and connection, the stability is poor and it is easy to loosen. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages in the existing technology that the existing self-sealing nuts have poor sealing effects, and dust or external particles may enter the connection, affecting the connection tightness. At the same time, after installation and connection, the stability is poor and it is easy to loosen, and a self-sealing nut is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A self-sealing nut, including a nut body, a bearing seat is fixedly connected to the nut body, a connecting column is provided on the nut body, an external thread is provided on the connecting column, a connecting hole is provided in each part of the connecting column, and an internal thread is provided in the connecting hole;

[0007] A sealing mechanism, which is arranged on the nut body to enhance the connection sealing performance;

[0008] A stabilizing mechanism, which is arranged on the nut body to make the nut body more stable and not easy to loosen.

[0009] In a possible design, the sealing mechanism includes a sealing disc fixedly connected to the nut body and a sealing ring fixedly connected to the sealing disc.

[0010] In a possible design, the sealing ring is made of elastic rubber material.

[0011] In a possible design, the outer surface of the nut body is sprayed with an anti-corrosion coating.

[0012] In a possible design, the stabilizing mechanism includes an adhesive sticker fixedly connected to the bearing seat, and a sealing film is provided on the outer surface of the adhesive sticker.

[0013] In a possible design, the anti-corrosion coating is one of a galvanized coating, a nickel-plated coating, a fluoroplastic coating, a ceramic coating or an anti-corrosion paint.

[0014] In this application, during use, first remove the film covering the outer surface of the adhesive patch, and then connect the nut body to the object to be connected. Since the sealing disc and the sealing ring are provided, a sealing structure can be formed at the connection, which can enhance the sealing performance. At the same time, the adhesive patch will firmly adhere to the connected object, making the nut body more stable, preventing the nut body from loosening. At the same time, the outer surface of the nut body is coated with an anti-corrosion coating, which can increase the anti-corrosion ability of the nut body and improve the service life.

[0015] By setting the sealing mechanism in the present utility model, the sealing performance of the nut body can be enhanced, preventing external particles or dust from entering the connection. At the same time, through the stabilizing mechanism, the nut body can be prevented from loosening, making the connection more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Embodiment 1

[0023] Referring to Figures 1-4 , a self-sealing nut, which is applied in the field of fasteners, includes a nut body 1. A bearing seat 2 is fixedly connected to the nut body 1. A connecting column is provided on the nut body 1. An external thread 3 is provided on the connecting column for threaded connection with other components. A connecting hole is also provided inside the connecting column, and an internal thread 4 is provided in the connecting hole to facilitate connection with other fasteners or components.

[0024] To enhance the sealing performance of the connection, a sealing mechanism is provided on the nut body 1 in this embodiment. The sealing mechanism includes a sealing disc 6 fixedly connected to the nut body 1 and a sealing ring 7 fixedly connected to the sealing disc 6. The sealing ring 7 is made of elastic rubber material, which can closely fit the connection part and enhance the sealing performance.

[0025] To improve the stability of the nut, a stability mechanism is also provided in this embodiment. The stability mechanism includes an adhesive patch 5 fixedly connected to the bearing seat 2. A sealing film is provided on the outer surface of the adhesive patch 5. When in use, the sealing film is torn off and the adhesive patch 5 is pasted at the position to be fixed, thereby increasing the friction between the nut and the connecting component and improving the stability of the connection.

[0026] In addition, to improve the durability of the nut, a galvanized coating is sprayed on the outer surface of the nut body 1 in this embodiment. The galvanized coating can effectively resist the erosion of the external environment and extend the service life of the nut.

[0027] Embodiment Two: Nickel-plated Coating Self-sealing Nut

[0028] This embodiment is similar to Embodiment One. The difference is that the outer surface of the nut body 1 is sprayed with a nickel-plated coating. The nickel-plated coating also has excellent corrosion resistance and can effectively resist the erosion of the external environment to protect the nut from damage. The remaining structures and implementation methods are the same as those in Embodiment One.

[0029] Embodiment Three: Fluoroplastic Coating Self-sealing Nut

[0030] For the self-sealing nut in this embodiment, the outer surface of the nut body 1 is sprayed with a fluoroplastic coating. The fluoroplastic coating has excellent chemical corrosion resistance and is especially suitable for use in harsh environments such as strong acids and strong alkalis. The structures and implementation methods of the remaining parts are the same as those in Embodiment One.

[0031] Embodiment Four: Ceramic Coating Self-sealing Nut

[0032] In this embodiment, the outer surface of the nut body 1 is sprayed with a ceramic coating. The ceramic coating has high hardness and good wear resistance, which can effectively improve the durability of the nut. At the same time, the ceramic coating also has good heat insulation performance and can maintain stable performance in high-temperature environments. The structures and implementation methods of the remaining parts are the same as those in Embodiment One.
