Description

Technical Field

[0001] This application belongs to the field of pipe fitting connection technology, and more specifically, relates to a sealing and rubber-coated stainless steel threaded pipe fitting connection structure. Background Technology

[0002] Existing threaded connections only provide rigid connections and do not offer a sealing function. If a seal is required, raw rubber tape needs to be wrapped around the external threads to achieve the desired sealing effect. However, wrapping the raw rubber tape requires manual operation by workers on-site. This operation has two drawbacks: firstly, it affects installation efficiency; secondly, due to improper operation by on-site workers, the raw rubber tape may not be wrapped properly, leading to leaks. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings in the prior art, the purpose of this application is to provide a sealing and rubber-coated stainless steel threaded pipe fitting connection structure, which is simple and compact, saves pipe installation time, and avoids water leakage caused by improper operation of workers wrapping raw rubber tape.

[0004] The technical means adopted in this application to solve the above-mentioned technical problems are: This application provides a sealing and rubber-coated stainless steel threaded pipe fitting connection structure, including: The first pipe fitting has a first threaded section on its outer wall and an abutment post at its end. The second pipe fitting has a second threaded section on its outer wall that mates with the first threaded section. The second pipe fitting is sleeved on the first pipe fitting. The first threaded section and the second threaded section are threadedly connected. The second threaded section is provided with a rubber ring groove. A sealing ring is fitted into the ring groove, and the outer wall of the abutting post abuts against the sealing ring.

[0005] Preferably, the sealing ring is provided with a sealing protrusion, and the outer wall of the abutting post abuts against the sealing protrusion.

[0006] Preferably, multiple sealing protrusions are provided.

[0007] Preferably, the end of the abutment post is configured with a rounded edge.

[0008] Compared with the prior art, the sealing rubber-coated stainless steel threaded pipe fitting connection structure of this application sets up a first pipe fitting and a second pipe fitting. By setting an abutment post at the end of the first pipe fitting, the first pipe fitting and the second pipe fitting are rotated together, and the sealing rubber ring is tightly attached to the outer wall of the abutment post to achieve a seal. This is convenient and quick, saves pipe fitting installation time, and avoids water leakage caused by improper operation of workers wrapping raw rubber tape. Attached Figure Description

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0015] It should be noted that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. Similar reference numerals and letters denote similar items in the following figures; therefore, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0016] like Figures 1-3As shown, this embodiment provides a sealing rubber-coated stainless steel threaded pipe connection structure, including a first pipe 1, a second pipe 2, and a sealing rubber ring 3. The outer wall of the first pipe 1 is provided with a first threaded section 1a, and the end of the first pipe 1 is provided with an abutment post 1b. The outer wall of the second pipe 2 is provided with a second threaded section 2a that mates with the first threaded section 1a. The second pipe 2 is sleeved on the first pipe 1, and the first threaded section 1a and the second threaded section 2a are threadedly connected. The second threaded section 2a is provided with a rubber ring groove. The sealing rubber ring 3 is sleeved on the rubber ring groove, and the outer wall of the abutment post 1b abuts against the sealing rubber ring 3.

[0017] In some preferred embodiments of this utility model, the sealing ring 3 is provided with a sealing protrusion 3a, and the outer wall of the abutting post 1b abuts against the sealing protrusion 3a. Thus, the sealing protrusion 3a can abut against the outer wall of the abutting post 1b, and the deformation and compression of the sealing protrusion 3a ensures a tight seal.

[0018] In some preferred embodiments of this invention, multiple sealing protrusions 3a are provided. This further improves the sealing reliability.

[0019] In some preferred embodiments of this invention, the end of the abutment post 1b is configured with a rounded edge. This rounded edge structure facilitates the insertion of the abutment post 1b into the second pipe fitting 2.

[0020] Compared with the prior art, the sealing rubber-coated stainless steel threaded pipe fitting connection structure of this application sets up a first pipe fitting 1 and a second pipe fitting 2. By setting an abutment post 1b at the end of the first pipe fitting 1, the first pipe fitting 1 and the second pipe fitting 2 are rotated together, and the sealing rubber ring 3 is tightly attached to the outer wall of the abutment post 1b to achieve a seal. This is convenient and quick, saves pipe fitting installation time, and avoids water leakage caused by improper operation of workers wrapping raw rubber tape.
