Description

Technical Field

[0001] This application relates to the field of water pipe sealing rings, and more particularly to a universal rotating sealing ring. Background Technology

[0002] Sealing rings are often needed at water pipe joints to seal gaps and improve the sealing of the pipes. To enhance ease of use, two water pipes can be connected via a sealing ring, allowing one pipe to swing relative to the other, thus enabling users to control the direction of water flow.

[0003] The existing omnidirectional rotating water pipe structure includes an inlet pipe, an outlet pipe, and a sealing ring. The inlet pipe has a fixed connector at its end, which is a threaded cylinder. The outlet pipe has a movable connector at its end, which is also a threaded cylinder. The outlet pipe has an abutting protrusion at its end, which is engaged in the movable connector. There is a gap between the outlet pipe and the movable connector. After the movable connector is threadedly connected to the fixed connector, the outlet pipe can swing within the movable connector. The sealing ring is located in the fixed connector and abuts against the abutting protrusion. When the outlet pipe swings and rotates relative to the inlet pipe, the sealing ring deforms and seals the gap between the outlet pipe and the inlet pipe.

[0004] The aforementioned technical solutions have the following drawbacks: after repeated movement of the water outlet pipe, wear is easily generated between the water outlet pipe and the sealing ring, causing the sealing ring to deform and resulting in leakage. Utility Model Content

[0005] To improve the sealing performance between two water pipes that are connected in a movable manner, this application provides a universal rotating sealing ring.

[0006] The universal rotary sealing ring provided in this application adopts the following technical solution:

[0007] A universal rotating sealing ring includes a sealing ring body and an inclined convex circle. The sealing ring body is a cylindrical structure, and the inclined convex circle is a cylindrical structure with different diameters at both ends. The diameter of the inclined convex circle gradually changes along the axial direction. The inclined convex circle is disposed inside the sealing ring body, and the end face of the larger diameter end of the inclined convex circle is connected to the end face of the sealing ring body.

[0008] By adopting the above technical solution, and by setting an inclined convex circle inside the sealing ring body, the user can insert the water outlet pipe into the inclined convex circle. The inclined convex circle fits onto the outer wall of the water outlet pipe, achieving a sealing effect. The inclined convex circle supports and holds the abutting convex circle at the end of the water outlet pipe. When the connectors at the ends of the water inlet pipe and the water outlet pipe are connected to each other, the sealing ring body is located inside the cylindrical connector. The sealing ring body plays a sealing role, which can reduce the probability of fluid leakage in the pipeline. When the water outlet pipe swings or rotates relative to the water inlet pipe, the water outlet pipe moves and squeezes the inclined convex circle, causing the inclined convex circle to deform. The friction is small when the water outlet pipe moves, and it is easier to rotate the water outlet pipe. After repeated movement of the water outlet pipe, the wear on the inclined convex circle is small, and the sealing ring body maintains a constant shape, thereby enabling the sealing ring body to maintain better sealing performance and making the sealing between the water inlet pipe and the water outlet pipe better.

[0009] Optionally, the inclined convex circle has an upper contact plane and a lower contact plane on the side with the smaller diameter, and the upper contact plane and the lower contact plane are parallel to the end face of the sealing ring body.

[0010] By adopting the above technical solution, by opening an upper contact plane and a lower contact plane on the inclined convex circle, when the water outlet pipe is inserted into the inclined convex circle, the abutting convex circle at the end of the water outlet pipe fits with the inclined convex circle. When the water outlet pipe swings, the gap between the water outlet pipe and the inclined convex circle is small, and the sealing performance is better.

[0011] Optionally, the diameters of the two end faces of the sealing ring body are different.

[0012] By adopting the above technical solution, the two ends of the sealing ring body have different diameters, allowing the user to insert the smaller diameter end of the sealing ring body into the pipe, thus enabling the sealing ring body to be easily and quickly inserted into the pipe for installation.

[0013] Optionally, the outer wall of the sealing ring body is provided with multiple snap-fit ​​blocks, which protrude and are used to snap into the pipe.

[0014] By adopting the above technical solution, multiple snap-fit ​​blocks are set on the outer wall of the sealing ring body, which can be snapped into the pipe, thereby improving the stability of the sealing ring body installed in the pipe and reducing the probability of the sealing ring body loosening due to water flow impact.

[0015] Optionally, the snap-fit ​​block has an inclined surface, which is located on the end face of the snap-fit ​​block facing the side with the smaller diameter of the sealing ring body.

[0016] By adopting the above technical solution, and by creating a bevel on the snap-fit ​​block, when the user inserts the sealing ring body into the pipe, the end of the pipe abuts against the bevel, which can improve the efficiency of installing the sealing ring body into the pipe.

[0017] Optionally, a water-sealing ring is provided on the end face of the sealing ring body. The water-sealing ring is a circular protrusion and is coaxially arranged with the sealing ring body.

[0018] By adopting the above technical solution, a water-sealing ring is set on the end face of the sealing ring body. When the sealing ring body is inserted into the pipe connector, the end face of the sealing ring body abuts against the inner wall of the connector, thereby allowing the water-sealing ring to deform and seal the gap between the sealing ring body and the connector, thus improving the pipe sealing performance.

[0019] Optionally, the sealing ring body is coaxially arranged with the inclined convex circle.

[0020] By adopting the above technical solution, and by setting the sealing ring body and the inclined convex circle coaxially, when the water outlet pipe rotates relative to the water inlet pipe, the inclined convex circle can deform and fit against the surface of the water outlet pipe, allowing the user to swing the water outlet pipe in any direction, making the movement direction of the water outlet pipe more flexible.

[0021] Optionally, the inner wall of the sealing ring body is provided with an inner convex circle, which is coaxially connected with the sealing ring body.

[0022] By adopting the above technical solution, by setting an inner convex circle inside the sealing ring body, the inner convex circle and the inclined convex circle can be respectively set on the upper and lower sides of the abutting convex circle. When the water outlet pipe swings relative to the water inlet pipe, the inner convex circle supports the abutting convex circle, reducing the probability of the water outlet pipe sliding inside the inclined convex circle.

[0023] In summary, the beneficial technical effects of this application are as follows:

[0024] 1. By setting an inclined convex circle inside the sealing ring body, the user can insert the water outlet pipe into the inclined convex circle. The inclined convex circle fits on the outer wall of the water outlet pipe, achieving a sealing effect. The inclined convex circle supports and holds the abutting convex circle at the end of the water outlet pipe. When the connectors at the ends of the water inlet pipe and the water outlet pipe are connected to each other, the sealing ring body is located inside the cylindrical connector. The sealing ring body plays a sealing role, which can reduce the chance of fluid leakage in the pipe. When the water outlet pipe swings or rotates relative to the water inlet pipe, the water outlet pipe moves and squeezes the inclined convex circle, causing the inclined convex circle to deform. The friction is small when the water outlet pipe moves, and it is easier to rotate the water outlet pipe. After repeated movement of the water outlet pipe, the wear on the inclined convex circle is small, and the sealing ring body maintains a constant shape, thereby enabling the sealing ring body to maintain better sealing performance and making the sealing between the water inlet pipe and the water outlet pipe better.

[0025] 2. By opening an upper contact plane and a lower contact plane on the inclined convex circle, when the water outlet pipe is inserted into the inclined convex circle, the abutting convex circle at the end of the water outlet pipe fits against the inclined convex circle. When the water outlet pipe swings, the gap between the water outlet pipe and the inclined convex circle is small, and the sealing performance is better.

[0026] 3. By setting multiple snap-fit ​​blocks on the outer wall of the sealing ring body, the snap-fit ​​blocks can be snapped into the pipe, thereby improving the stability of the sealing ring body installed in the pipe and reducing the chance of the sealing ring body loosening due to water flow impact.

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] This application discloses a universal rotating sealing ring, referring to... Figure 1 , Figure 2 and Figure 3The system includes a sealing ring body 1 and an inclined convex circle 2. The sealing ring body 1 is a cylindrical structure, and the inclined convex circle 2 is located inside the sealing ring body 1. The inclined convex circle 2 is a frustum-shaped structure with a through hole in the middle. The side with the larger diameter at the upper end of the inclined convex circle 2 is connected to the end face of the sealing ring body 1, and the inclined convex circle 2 is coaxially arranged with the sealing ring body 1. The sealing ring body 1 and the inclined convex circle 2 are integrally molded and connected, with the inclined convex circle 2 entirely located inside the sealing ring body 1. The sealing ring body 1 is used to be installed between the inlet pipe 5 and the outlet pipe 6. The end of the outlet pipe 6 is provided with an abutment convex circle 62, which is used to be locked inside the sealing ring body 1. When the user uses the universal rotating part to connect the inlet pipe 5 and the outlet pipe 6, the outlet pipe 6 can rotate relative to the inlet pipe 5. When the outlet pipe 6 rotates, the abutment convex circle 62 is always in contact with the outer surface of the inclined convex circle 2 inside the sealing ring body 1, thereby enabling the inclined convex circle 2 to achieve a sealing effect. When the water outlet pipe 6 is rotated, the inclined convex circle 2 can deform and abut against the water outlet pipe 6, thereby reducing the difficulty of rotating the water outlet pipe 6 and making it easier to use.

[0035] Reference Figure 4 When water flows through the pipe, the water flow applies pressure to the inclined convex circle 2, causing the inclined convex circle 2 to deform. The inclined convex circle 2 is impacted and deformed by the water flow, and its height becomes smaller. At this time, the diameter of the through hole in the middle of the inclined convex circle 2 becomes smaller, so that the inclined convex circle 2 can tightly abut against the outer wall of the water outlet pipe 6, so that the water outlet pipe 6 and the inclined convex circle 2 have better sealing performance and reduce the probability of fluid leakage along the outer wall of the water outlet pipe 6.

[0036] Reference Figure 3 and Figure 4 The inlet pipe 5 is provided with a fixed connector 51 at its end. The fixed connector 51 is a cylindrical structure and is fixedly connected to the inlet pipe 5. The outlet pipe 6 is provided with a movable connector 61 at its end. The movable connector 61 is a cylindrical structure and is movably connected to the outlet pipe 6. The outlet pipe 6 can rotate relative to the movable connector 61. The fixed connector 51 is threadedly connected to the movable connector 61.

[0037] Reference Figure 2 The outer side of the sealing ring body 1 is provided with an upper contact surface 11 and a lower contact surface 12. The diameters of the circles formed by the cross-sections of the upper contact surface 11 and the lower contact surface 12 are different, so that the user can insert the end face of the sealing ring body 1 with the smaller diameter into the connector for easy installation.

[0038] Reference Figure 2Multiple snap-fit ​​blocks 3 are provided on the outer wall of the sealing ring body 1. The snap-fit ​​blocks 3 are integrally formed and connected to the sealing ring body 1 through a mold. The multiple snap-fit ​​blocks 3 are equidistantly spaced along the circumference of the sealing ring body 1. When the sealing ring body 1 is snapped into the pipe connector, the snap-fit ​​blocks 3 snap into the inner wall of the pipe connector, which can reduce the probability of the sealing ring body 1 moving inside the pipe connector and keep the sealing ring body 1 and the pipe connector in a stable sealing connection.

[0039] Reference Figure 4 The snap-fit ​​block 3 has an inclined surface 31. The inclined surface 31 is located on the side of the snap-fit ​​block 3 facing the side with the smaller cross-sectional diameter of the sealing ring body 1. When the sealing ring body 1 is installed in the pipe connector, the inclined surface 31 contacts the port of the pipe connector, which can conveniently and quickly insert the sealing ring body 1 into the pipe connector.

[0040] Reference Figure 2 A water-sealing ring 4 is provided on the end face of the sealing ring body 1. The water-sealing ring 4 is a circular protrusion and is coaxially arranged with the sealing ring body 1. When the sealing ring body 1 is installed in the pipe connector, the water-sealing ring 4 abuts against the inner wall of the pipe connector, further improving the sealing performance of the sealing ring body 1 and reducing the probability of fluid leakage through the gaps on the end face of the sealing ring body 1.

[0041] Reference Figure 1 and Figure 2 The inclined convex circle 2 has an upper contact plane 21 and a lower contact plane 22, which are located on the end face of the inclined convex circle 2 with the smaller diameter. The upper contact plane 21 and the lower contact plane 22 are located on the upper and lower sides of the end face of the inclined convex circle 2, respectively, and both the upper contact plane 21 and the lower contact plane 22 are parallel to the end face of the sealing ring body 1. When the user inserts the water outlet pipe 6 into the through hole in the middle of the inclined convex circle 2, the abutting convex circle 62 can keep in contact with the upper contact plane 21 or the lower contact plane 22, improving the sealing performance of the connection between the inclined convex circle 2 and the water outlet pipe 6.

[0042] Reference Figure 5 In other embodiments, an inner convex circle 13 is provided on the inner sidewall of the sealing ring body 1. The inner convex circle 13 is a circular ring structure and is coaxially disposed inside the sealing ring body 1, and is integrally disposed with the sealing ring body 1. When the water outlet pipe 6 is inserted into the through hole in the middle of the inclined convex circle 2, the abutting convex circle 62 can be disposed between the inner convex circle 13 and the inclined convex circle 2. The inner convex circle 13 and the inclined convex circle 2 abut against the inner and outer sides of the water outlet pipe 6, further improving the connection sealing performance.

[0043] The implementation principle of this application embodiment is as follows: by coaxially setting an inclined convex circle 2 inside the sealing ring body 1, the water outlet pipe 6 can be inserted into the through hole in the middle of the inclined convex circle 2. The abutting convex circle 62 at the end of the water outlet pipe 6 can be locked on the end face of the inclined convex circle 2. When the water outlet pipe 6 moves and swings, the inclined convex circle 2 deforms, thereby making it easier to rotate the water outlet pipe 6. By setting a snap-fit ​​block 3 outside the sealing ring body 1, the snap-fit ​​block 3 can be locked on the inner wall of the pipe, thereby improving the installation stability of the sealing ring body 1 and reducing the probability of the sealing ring body 1 loosening due to water flow impact.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
