Description

Technical Field

[0001] This utility model relates to the field of sealing ring technology, and in particular to a waterproof ring for threaded pipes. Background Technology

[0002] Threaded pipe fittings are widely used in cable protection, fluid transportation, and other fields due to their excellent mechanical strength. When transporting liquids, sealing rings or sealants are typically used at threaded connections to ensure a tight seal and prevent leakage. Some threaded pipes also employ special materials or additional coatings to enhance corrosion resistance and water resistance, making them suitable for humid or underwater environments.

[0003] Traditional threaded pipe fittings primarily rely on sealing rings and sealants for sealing. However, these materials are susceptible to environmental factors such as temperature changes, humidity, and chemical corrosion during long-term use, leading to gradual aging, hardening, or deformation. Once the sealing ring loses its elasticity, or the sealant cracks or peels off, the sealing performance will significantly decrease, potentially causing leaks, especially under high pressure or frequent vibration conditions. This lack of reliability not only increases maintenance costs but also limits the practical application of threaded pipes. Utility Model Content

[0004] The technical problem this invention aims to solve is that traditional waterproof rings, which require the use of sealant, generally have limited durability after long-term use.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a waterproof ring for threaded pipes, including a sealing ring body, wherein the sealing ring body is a tubular structure made of rubber material, and a thickened ring layer is set on the central side. An annular skeleton is embedded inside the thickened ring layer. The sealing ring body is filled with a number of supporting ribs, and side rings are fixedly set at the top and bottom of the supporting ribs respectively.

[0006] As a further improvement of this utility model, the supporting ribs are evenly and vertically arranged inside the sealing ring body, and multiple supporting ribs are located on the inner side of the annular skeleton.

[0007] As a further improvement of this utility model, the top and bottom sides of the sealing ring are reinforced with ring frames, and the side rings are embedded inside the ring frames.

[0008] As a further improvement of this utility model, the edge of the ring frame is provided with a rounded transition.

[0009] As a further improvement of this utility model, the ring skeleton is made of polyurethane material, and the diameter of the side rings is smaller than the diameter of the ring skeleton.

[0010] As a further improvement of this utility model, anti-slip diagonal patterns are provided around the outer wall of the ring frame.

[0011] The beneficial effects of this utility model are as follows: This utility model sets the waterproof ring as an internal sealing ring body, and by setting an annular skeleton inside the ring body, it ensures that the sealing ring body has an outward expansion force. At the same time, by setting several supporting ribs and side rings, it can ensure that the sealing ring body is stably placed inside the threaded pipe fitting, ensuring the sealing and waterproof performance of the threaded pipe fitting, and avoiding the risk of peeling and aging caused by using sealant to reinforce the sealing ring body.

[0017] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to their structure and are relative concepts. Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.

[0018] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0019] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] This utility model provides a waterproof ring for threaded pipes, including a sealing ring body 1;

[0021] As attached Figure 1-4As shown, the sealing ring 1 is a tubular structure made entirely of rubber, with a thickened ring layer 2 at its center. An annular skeleton 3, made of polyurethane, is embedded inside the thickened ring layer 2. The annular skeleton 3 effectively provides outward expansion force to the sealing ring, enhancing its sealing performance. The sealing ring 1 is filled with several supporting ribs 4, which are evenly and vertically arranged inside the sealing ring 1, with multiple supporting ribs 4 located inside the annular skeleton 3; this enhances the stable support effect.

[0022] As attached Figure 2-4 As shown, side rings 5 ​​are fixedly installed at the top and bottom of the support frame 4, respectively. Meanwhile, ring frames 6 are reinforced on both sides of the top and bottom of the sealing ring body 1, and the diameter of the side rings 5 ​​is smaller than the diameter of the annular skeleton 3. The side rings 5 ​​are embedded inside the ring frames 6, improving the ease of inserting the sealing ring body 1 into the threaded pipe fitting. Furthermore, the edges of the ring frames 6 have rounded transitions to optimize water flow and reduce obstruction. Anti-slip diagonal lines are formed around the outer wall of the ring frames 6 to enhance the stability of the connection with the pipe wall.

[0023] Working Principle: In practical implementation, this invention uses a pipe fitting with a first thread and a second thread. The ring frame 6 at one end of the sealing ring 1 is aligned with the inner cavity of the first threaded pipe fitting, and the sealing ring 1 is inserted into the inner cavity. Subsequently, through the support of multiple supporting strips 4 and side rings 5, the sealing ring 1 is continuously pushed towards the interior of the first threaded pipe fitting until the thickened ring layer 2 and the supporting strips 4 within the thickened ring layer 2 move to the joint of the first threaded pipe fitting. The second threaded pipe fitting is then moved in the same manner, with its inner cavity aligned with the sealing ring 1, until it reaches the threaded connection layer on the outer side of the first threaded pipe fitting, where the second threaded pipe fitting and the first threaded pipe fitting are threaded together. At this point, because the supporting strips 4 within the thickened ring layer 2 are located on one side of the first threaded pipe fitting, reliable sealing is ensured while maintaining a threaded connection between the two.

[0024] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
