Description

Technical Field

[0001] This utility model relates to the field of exhaust pipe technology, and in particular to a quick-release exhaust pipe sealing ring. Background Technology

[0002] With the continuous development of automotive technology, the requirements for vehicle exhaust emissions are becoming increasingly stringent. As an important component of a vehicle, the sealing performance of the exhaust system is crucial. Exhaust pipe sealing rings are mainly used to connect various parts of the exhaust pipe, prevent exhaust gas leakage, and ensure that exhaust gases can be discharged smoothly and meet emission standards. The sealing ring is a ring-shaped sealing component that is usually placed inside the exhaust pipe and relies on its own elasticity to press against the inner wall of the exhaust pipe, thus playing a role in sealing and preventing leakage.

[0003] When a traditional exhaust pipe sealing ring malfunctions, it relies on its own elasticity to fit tightly against the inner wall of the exhaust pipe. Furthermore, the inner wall of the sealing ring is designed to be relatively smooth and lacks sufficient stress points. This makes it difficult for repair personnel to remove it from the inside of the exhaust pipe. In practice, it often requires a lot of time and effort, and may even require special tools and complex operating skills to remove and replace the damaged sealing ring. Utility Model Content

[0004] To overcome the technical defects of the existing technology, this utility model provides a quick-release exhaust pipe sealing ring.

[0005] The technical solution adopted by this utility model is: a quick-release exhaust pipe sealing ring, including an outer ring and an inner ring. The inner ring is slidably connected to the inside of the outer ring. The inner wall of the outer ring is provided with a number of arc-shaped protrusions arranged in a circle. The arc-shaped protrusions are used to deform the stress parts of the inner ring when it moves. The inner ring includes a number of hardened parts arranged in a circle. The hardened parts are used to prevent the inner ring from detaching from the inner ring when it is under force. A softening part is provided between every two adjacent hardened parts. When the softening part is deformed under force, it provides a stress point.

[0006] Preferably, the outer surface of the inner ring is provided with a plurality of arc-shaped grooves that are adapted to the arc-shaped protrusions, and the number of arc-shaped grooves is the same as the number of arc-shaped protrusions, and the arc-shaped protrusions are made of plastic.

[0007] Preferably, the inner ring has a plurality of force-receiving grooves arranged in a circular pattern.

[0008] Preferably, the inner wall of the outer ring is provided with two symmetrical constraint rings.

[0009] Preferably, the outer ring is made of rubber, and the constraint ring is made of plastic.

[0010] Preferably, the outer ring and the constraint ring are integrally formed structures, and the hardening part and the softening part are also integrally formed structures.

[0011] Preferably, the hardened part is made of plastic and the softened part is made of rubber.

[0012] The beneficial effects of this utility model are: through the cooperation of the arc-shaped protrusion and the softening part, the softening part can be deformed when the inner ring is rotated, providing a larger force point. The entire sealing ring can be removed by pulling the deformed part, avoiding the inconvenience of removing the sealing ring due to the lack of a force point. Through the cooperation of the hardening part and the constraint ring, and since both are made of plastic, the inner ring is prevented from falling off the outer ring when pulled, thus preventing it from being completely removed.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figure 1-5As shown, this embodiment provides a quick-release exhaust pipe sealing ring, including an outer ring 1 and an inner ring 2. The inner ring 2 is slidably connected to the inside of the outer ring 1 and can move along the radial direction of the outer ring 1. The inner wall of the outer ring 1 is provided with a number of arc-shaped protrusions 3 arranged in a circular pattern. The arc-shaped protrusions 3 are used to deform the stress points of the inner ring 2 when it moves. The outer surface of the inner ring 2 is provided with a number of arc-shaped grooves 6 that are adapted to the arc-shaped protrusions 3, and the number of arc-shaped grooves 6 is the same as the number of arc-shaped protrusions 3. The arc-shaped protrusions 3 are made of plastic. When the inner ring 2 is rotated under force, the inner ring 2 applies pressure to the arc-shaped protrusions 3, causing it to deform and bulge, creating a new stress point. By simply clamping this part, the whole can be effectively removed, avoiding the situation where the inner wall surface of the sealing ring is relatively smooth and has no stress point, making removal difficult.

[0021] The inner ring 2 includes several circumferentially arranged hardened parts 4, which are made of plastic. The hardened parts 4 are used to prevent the inner ring 2 from detaching from the inner ring 2 under force. The hardened parts are relatively hard, providing support for the inner ring 2. At the same time, the hardened parts 4 can prevent deformation and avoid falling off the inner ring 2 after deformation. A softening part 5 is provided between every two adjacent hardened parts 4. The softening part 5 is made of rubber. When the softening part 5 is deformed under force, it provides a stress point, making it easier to disassemble. The whole can be removed by simply pulling on the deformed part. The hardened parts 4 and the softening parts 5 are also integrally formed structures, forming a whole, to avoid the situation where the adhesion strength between the hardened parts 4 is insufficient and breakage occurs during use.

[0022] The inner ring 2 has several force-receiving grooves 7 arranged in a circle. The force-receiving grooves 7 can provide force points and avoid insufficient force to allow the inner ring 2 to rotate, so that the inner ring 2 cannot be deformed by the arc-shaped protrusions 3, thus affecting the disassembly efficiency.

[0023] The inner wall of the outer ring 1 is provided with two symmetrical constraint rings 8. The constraint rings 8 are made of plastic and are relatively hard. Together with the hardening part 4, they ensure that the sealing ring retains its original shape under force, preventing deformation of the overall frame during disassembly. The outer ring 1 and the constraint rings 8 are integrally molded, preventing the constraint rings 8 from being squeezed and breaking when the inner ring 2 is pulled. The integrally molded structure of the outer ring 1 and the constraint rings 8 has higher overall strength and is not easily damaged. The two constraint rings 8 and the outer ring 1 can form a circular groove for the movement of the inner ring 2, preventing the inner ring 2 from being misaligned during movement. At the same time, it can constrain the position of the inner ring 2 and prevent the inner ring 2 and the outer ring 1 from separating. The outer ring 1 is made of rubber and can deform under pressure to seal the gap. The constraint rings 8 are made of plastic and are relatively hard and not easily deformed. They can constrain the position of the inner ring 2 and the outer ring 1 and prevent separation during disassembly, which would make it impossible to remove the sealing ring as a whole.

[0024] During disassembly, the exhaust pipe is opened to expose the internal sealing ring. First, observe the position of the force groove 7. Manually insert your finger into the force groove 7 and slowly apply force to make the inner ring 2 move radially along the outer ring 1. Under the action of the force groove 7, the softening part 5, the hardening part 4, and the softening part 5 are pushed to move in sequence. The softening part 5 near the arc-shaped protrusion 3 is constrained by the arc-shaped protrusion 3, causing the softening part 5 to deform along the arc surface of the arc-shaped protrusion 3. The deformed part passes over the inner wall of the inner ring 2 and protrudes from the smooth inner wall of the inner ring 2, naturally forming a new force point. Pulling this force point causes the inner ring 2 to move away from the exhaust pipe. At the same time, under the interaction of the hardening part 4 and the constraint ring 8, the force of disassembly can be introduced into the outer ring 1, thereby achieving the purpose of simultaneous disassembly and making it more convenient.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.

All such changes and modifications fall within the scope of the invention as claimed, which is defined by the appended claims and their equivalents.
