Description

Technical Field

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

[0002] Rubber seals are fundamental components widely used in machinery, automobiles, hydraulics, pneumatics, and other fields. Their main function is to form an effective seal between two or more components, preventing leakage of media (such as oil, water, and gas) and the intrusion of external contaminants. Currently, most commercially available rubber seals are one-piece structures made of a single material. While these seals perform well under many standard operating conditions, their limitations are becoming increasingly apparent in demanding applications. Traditional one-piece or simply assembled seals lack a reliable internal mechanical interlocking structure. Under high internal pressure or external vibration, gaps or relative displacement can easily occur between their components, disrupting the continuity of the sealing interface and leading to leakage. Therefore, we propose a new type of rubber seal. Utility Model Content

[0003] The main objective of this invention is to provide a rubber sealing ring that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A rubber sealing ring includes a middle ring, upper rings on both opposite surfaces of the middle ring, an installation groove on the upper surface of the upper ring, a protective shell inside the installation groove, a fixing ring on both opposite surfaces of the inner wall of the installation groove, a fixing groove on the peripheral side and inner wall of the protective shell, a slot and a second slot respectively on the bottom surface of the upper ring, and an insert block on the right side of the slot on the bottom surface of the upper ring.

[0006] Preferably, the middle ring has slots on its two opposite surfaces, a connecting ring and a plug are respectively provided on its two opposite surfaces, and the middle ring and the inner ring of the upper ring are provided with elastic steel rings.

[0007] By adopting the above technical solution, the cooperation between the mounting groove and the protective shell provides surface protection and extends service life. The snap-fit ​​cooperation between the fixing ring and the fixing groove ensures that the protective shell is firmly fixed and prevents it from falling off under vibration or pressure.

[0008] Preferably, the inner wall of the upper ring is provided with an extrusion block, and the elastic steel ring has symmetrical extrusion grooves on its circumferential side.

[0009] Preferably, the shape and size of the mounting groove are adapted to the protective shell, the shape and size of the fixing ring are adapted to the fixing groove, the position of the fixing ring is adapted to the position of the fixing groove and is engaged with the fixing groove, and the edges of the fixing ring are rounded.

[0010] Preferably, the shape and size of the second slot are adapted to the first insert, the shape and size of the second insert are adapted to the first slot, and the shape and size of the slot are adapted to the connecting ring and engage with the connecting ring.

[0011] By adopting the above technical solution, a quick and reliable connection between the middle ring and the upper ring is achieved. The adaptable design of slot two with insert one, and insert two with slot one, ensures that the components automatically align during insertion, reducing installation difficulty and time. The snap-fit ​​engagement between the slot and the connecting ring provides additional mechanical locking, preventing disengagement under pressure or vibration, and enhancing the integrity and sealing performance of the sealing ring.

[0012] Preferably, the extrusion block has a hemispherical structure, and the shape and size of the extrusion block are adapted to the extrusion groove, and the extrusion block and the extrusion groove are fitted together.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. A robust mechanical interlock is formed through multiple insertion and snap-fit ​​connections between the middle and upper rings (such as the connecting ring and slot, insert one and slot two, and insert two and slot one). This design ensures that the components will not separate or misalign when the sealing ring is subjected to internal media pressure or external mechanical vibration, thus guaranteeing the integrity of the sealing interface and the long-term reliability of the seal. The built-in elastic steel ring provides strong support for the rubber body, effectively preventing the sealing ring from being crushed or permanently deformed under high pressure, and maintaining a stable sealing pressure.

[0015] 2. This utility model adopts a combined structure of a middle ring and two upper rings, breaking the limitations of traditional one-piece sealing rings. This modular design makes the assembly process like assembling building blocks, which can be completed quickly through simple plugging and pressing, significantly reducing the difficulty and time of installation. It effectively avoids the twisting or damage that may occur when installing large integral sealing rings in narrow spaces, while also improving the speed of replacement and maintenance, and enhancing portability and practicality.

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] A rubber sealing ring includes a middle ring 1, with upper rings 2 on both opposite surfaces of the middle ring 1. The upper surface of the upper ring 2 has an installation groove 20, and a protective shell 21 is disposed within the installation groove 20. A fixing ring 201 is disposed on both opposite surfaces of the inner wall of the installation groove 20. Fixing grooves 210 are formed on the circumferential side and inner wall of the protective shell 21. A slot 202 and a second slot 203 are respectively formed on the bottom surface of the upper ring 2. A second insert 204 is disposed on the bottom surface of the upper ring 2 to the right of the slot 202. A first slot 102 is formed on both opposite surfaces of the middle ring 1. A connecting ring 10 and a first insert 101 are respectively formed on both opposite surfaces of the middle ring 1. An elastic steel ring 3 is disposed within the inner rings of the middle ring 1 and the upper ring 2. An extrusion block 205 is disposed on the inner wall of the inner ring of the upper ring 2. Extrusion grooves 30 are symmetrically formed on the circumferential side of the elastic steel ring 3.

[0027] In this embodiment, the shape and size of the mounting groove 20 are adapted to the protective shell 21, the shape and size of the fixing ring 201 are adapted to the fixing groove 210, the position of the fixing ring 201 is adapted to the position of the fixing groove 210, and it is engaged with the fixing groove 210. The edges of the fixing ring 201 are rounded. The shape and size of the slot 203 are adapted to the insertion block 101, the shape and size of the insertion block 204 are adapted to the slot 102, the shape and size of the slot 202 are adapted to the connecting ring 10, and it is engaged with the connecting ring 10. The extrusion block 205 is a hemispherical structure, the shape and size of the extrusion block 205 are adapted to the extrusion groove 30, and the extrusion block 205 is engaged with the extrusion groove 30.

[0028] The above method involves aligning the two upper rings 2 from both sides of the middle ring 1 and pressing them downwards. The connecting ring 10 is inserted into the slot 202, producing a "click" sound, forming a complete three-layer sealing ring. The protective shell 21 is then pressed into the mounting groove 20 of the upper ring 2, and secured using the cooperation of the fixing ring 201 and the fixing groove 210, protecting the surface of the upper ring 2 and preventing wear. The elastic steel ring 3 provides strong support for the flexible body, preventing permanent plastic deformation of the sealing ring under high pressure. Insert block 101 and slot 203 and insert block 204 and slot 102 are then engaged to activate the positioning function. Yes, it guides the precise alignment of components during assembly and provides basic connection force to prevent radial misalignment between components. The hemispherical extrusion block 205 and extrusion groove 30 are inserted into the extrusion groove 30 of the elastic steel ring 3, effectively ensuring that the rigid frame is always in the design position and plays its due supporting role. The connecting ring 10 and the slot 202 are the core locking mechanism of the connection system. The connecting ring 10 is inserted into the slot 202 to form a strong mechanical lock, which mainly resists the component separation tendency caused by internal medium pressure or external vibration, ensuring the integrity of the structure under harsh working conditions.

[0029] It should be noted that, aligning the two upper rings 2 from both sides of the middle ring 1 and pressing them downwards, the connecting ring 10 snaps into the slot 202, producing a "click" sound, forming a complete three-layer sealing ring. The protective shell 21 is then pressed into the mounting groove 20 of the upper ring 2, and secured using the cooperation of the fixing ring 201 and the fixing groove 210, protecting the surface of the upper ring 2 from wear. The elastic steel ring 3 provides strong support for the flexible body, preventing permanent plastic deformation of the sealing ring under high pressure. Insert block 101 engages with slot 203, and insert block 204 engages with slot 102, activating the positioning function. Yes, it guides the precise alignment of components during assembly and provides basic connection force to prevent radial misalignment between components. The hemispherical extrusion block 205 and extrusion groove 30 are inserted into the extrusion groove 30 of the elastic steel ring 3, effectively ensuring that the rigid frame is always in the design position and plays its due supporting role. The connecting ring 10 and the slot 202 are the core locking mechanism of the connection system. The connecting ring 10 is inserted into the slot 202 to form a strong mechanical lock, which mainly resists the component separation tendency caused by internal medium pressure or external vibration, ensuring the integrity of the structure under harsh working conditions.
