Description

Technical Field

[0001] This utility model relates to the field of sealing ring technology, specifically a multi-layer stepped sealing rubber ring for automotive water tanks. Background Technology

[0002] Seals can be broadly classified into two categories: static seals and dynamic seals. Static seals mainly include gasket seals, sealant seals, and direct contact seals. Based on working pressure, static seals can be further divided into low-pressure and medium-pressure static seals and high-pressure static seals. Low-pressure and medium-pressure static seals commonly use gaskets made of softer materials and with wider widths, while high-pressure static seals use harder materials and metal gaskets with very narrow contact widths.

[0003] As indicated by announcement number CN203532731U, a rubber sealing ring is described. The device includes a coaxial annular plate-shaped body and a central hole. The intersecting edge ring located on one side of the annular plate-shaped body and the central hole is a rounded corner ring. Multiple suction cup grooves are designed on both sides of the annular plate-shaped body, and the suction cup grooves are filled with yellow grease.

[0004] The aforementioned device has a simple structure, poor sealing layers, and inadequate sealing effect during use, failing to achieve multi-layer sealing and leak prevention, which is not conducive to practical applications. Therefore, we proposed a multi-layer stepped sealing rubber ring for automotive water tanks to solve the problems mentioned above. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4 This utility model provides an embodiment of a multi-layer stepped sealing rubber ring for automotive water tanks, comprising a mounting ring 1, a sliding ring 2 slidably connected to the top and bottom of the mounting ring 1, a first annular pad 3 fixedly connected to the top and bottom of the mounting ring 1, a second annular pad 4 fixedly connected to one end of the sliding ring 2 near the mounting ring 1, a first annular sealing ring 5 installed on the outer wall of the mounting ring 1, a second annular sealing ring 6 installed on the outer wall of the sliding ring 2, four sets of first vertical grooves 7 provided on the top and bottom of the mounting ring 1, the four sets of first vertical grooves 7 being circumferentially distributed on the mounting ring 1 and penetrating the first annular pad 3, and four sets of retaining plates 8 installed on one end of the second annular pad 4 near the direction of the first annular pad 3, the retaining plates 8 being located inside the first vertical grooves 7. Please refer to [link to relevant documentation]. Figure 3 The first vertical groove 7 has two second vertical grooves 9 at both ends, and the first vertical groove 7 and the second vertical groove 9 are connected. A first damping spring 10 is installed at both ends of the lower part of the clamping plate 8, and a first abutment plate 11 is installed at the other end of the first damping spring 10. A telescopic rod 12 is installed inside the first damping spring 10. In use, the mounting ring 1 is fixed to the water tank base, the clamping plate 8 is located inside the first vertical groove 7, and the first abutment plate 11 is in contact with the inner wall of the second vertical groove 9 by the elastic force of the first damping spring 10. The cooperation of the first vertical groove 7, clamping plate 8, second vertical groove 9, first damping spring 10, and first abutment plate 11 can fix the upper and lower sliding rings 2 to the mounting ring 1. The combined action of the first annular gasket 3 and the second annular gasket 4 can improve the sealing between the mounting ring 1 and the sliding ring 2. The guide rail structure of the clamping plate 8 inserted into the first vertical groove 7 ensures that the sliding direction is controllable. Please refer to [link to relevant documentation]. Figure 3 The first annular sealing ring 5 has four sets of positioning grooves 13 at its top and bottom, which are distributed in a ring on the first annular sealing ring 5. The first annular gasket 3 and the second annular gasket 4 have four sets of positioning through holes 14 arranged in a ring. The second annular sealing ring 6 has four sets of positioning posts 15 installed in a ring at one end near the first annular sealing ring 5. The positioning posts 15 penetrate the positioning through holes 14 and are located inside the positioning grooves 13. Please refer to [link / reference]. Figure 3 One end of the positioning post 15 is provided with a limiting groove 16. Four sets of internal grooves 17 are provided above and below the first annular sealing ring 5. The internal grooves 17 are distributed in a ring on the first annular sealing ring 5. The internal grooves 17 are connected to the positioning groove 13 through the limiting through hole 18. A second damping spring 19 is fixedly installed on the side of the internal groove 17 away from the limiting through hole 18. A second abutment plate 20 is fixedly installed on the other side of the second damping spring 19. A limiting post 22 is fixedly installed on the other side of the second abutment plate 20. The limiting post 22 passes through the limiting through hole 18 and is located inside the limiting groove 16. Please refer to [link to relevant documentation]. Figure 2The second damping spring 19 has a fixing post 23 installed inside, which is fixedly connected to the second abutment plate 20. The outer wall of the first annular sealing ring 5 is provided with four sets of placement grooves 24, which are connected to the inner groove 17. Two fixing posts 23 pass through the inner groove 17 and are fixedly connected by a pull plate 25, which is located inside the placement groove 24. The positioning post 15 extends from the second annular sealing ring 6, passes through the positioning through hole 14, and is inserted into the positioning groove 13 of the first annular sealing ring 5 to ensure that the two sealing rings are aligned and to avoid misalignment that could lead to sealing failure. The limiting post 22 is inserted into the limiting groove 16 of the positioning post 15 under the push of the second damping spring 19 to prevent the positioning post 15 from coming out of the positioning groove 13 under vibration conditions. When it is necessary to separate the two sealing rings for maintenance, the pull plate 25 can be pulled to compress the second damping spring 19 and unlock the limiting post 22. The first annular sealing ring 5 is fixed to the outer wall of the mounting ring 1 to form a basic seal. The second annular sealing ring 6 is fixed to the outer wall of the sliding ring 2 and works in conjunction with the main sealing ring. The two sealing rings are staggered in a stepped manner. The coolant needs to break through the double physical barrier to leak. Even if one layer fails, the other layer can still maintain the seal.

[0023] Please see Figure 4 A silicone pad 21 is installed at the connection between the second abutment plate 20 and the limiting post 22. The silicone pad 21 fills the gap between the second abutment plate 20 and the inner groove 17, thereby sealing the inner groove 17 and the limiting through hole 18 and enhancing the sealing performance of the locking surface.

[0024] Please see Figure 1 A third annular sealing ring 26 is fixedly installed on the inner wall of the mounting ring 1. The third annular sealing ring 26 is located on the inner wall of the mounting ring 1 to prevent coolant from leaking from the mounting base surface, forming a third line of defense.
