Description

Technical Field

[0001] This utility model relates to the field of automotive exhaust bellows technology, and in particular to an automotive exhaust bellows that is easy to connect securely. Background Technology

[0002] The exhaust bellows is an important component of a vehicle's exhaust system, primarily used to connect the engine exhaust manifold to the muffler or other exhaust parts. It not only helps guide exhaust gases out but also absorbs vibrations, compensates for thermal expansion, and reduces noise.

[0003] For example, a convenient automotive exhaust bellows disclosed in CN221762047U includes a connecting sleeve. Two symmetrically distributed connecting ends are slidably fitted onto the inner wall of the connecting sleeve. A bellows body is fixedly connected to the end of the connecting end away from the connecting sleeve, and a connecting end two is fixedly connected to the end face of the bellows body away from the connecting end one. An annular groove is formed on the inner wall of the connecting sleeve. A guide plate is slidably connected inside the connecting end one. Two symmetrically distributed sealing elements are slidably connected to the inner wall of the annular groove, and the two sealing elements are in contact with each other. Each sealing element is fixedly connected to the guide plate. This invention uses the deformation of a spring two to push a rod into the insertion hole, limiting the insertion of the connecting end one, thereby ensuring the bellows is stably positioned and easy for operators to connect and use. However, because this automotive exhaust bellows only relies on the deformation of the spring to limit the insertion of the rod, the stability is poor. When the car vibrates, the rod may detach from the bellows, causing the bellows to loosen and fall off.

[0004] Therefore, a new type of automotive exhaust bellows has been developed that can improve the stability of bellows connections during vehicle exhaust, preventing the bellows from loosening and falling off, and facilitating a secure connection. Utility Model Content

[0005] To overcome the shortcomings of existing automotive exhaust bellows, which rely solely on the deformation of a spring to insert and limit the bellows, resulting in poor stability and the possibility of the insert detaching from the bellows when the vehicle vibrates, leading to the bellows loosening and falling off, this invention provides an automotive exhaust bellows that improves the stability of the bellows connection during vehicle exhaust, preventing the bellows from loosening and falling off, and facilitating a secure connection.

[0006] The technical solution of this utility model is: a car exhaust bellows that is easy to connect securely, including a bellows, a fixing sleeve, an exhaust pipe, a sealing component and a locking component. The bellows is connected to the fixing sleeves on both the left and right sides, and the exhaust pipe is snapped onto the fixing sleeves. The bellows is provided with a sealing component that can seal the exhaust pipe, and the fixing sleeve is provided with a locking component that can lock the exhaust pipe.

[0007] Furthermore, it also includes elastic sleeves, with elastic sleeves connected inside the fixed sleeves.

[0008] Furthermore, the sealing assembly includes a sealing cylinder, a sealing ring, and an expansion ring. Sealing cylinders are connected to both sides of the bellows. The sealing cylinders are located inside adjacent elastic sleeves. Sealing rings are connected to the side of the sealing cylinders that are far apart from each other. Expansion rings are connected to the sealing cylinders.

[0009] Furthermore, the locking assembly includes a rack, mounting blocks, locking blocks, pull rings, guide rods, and elastic elements. The upper and lower sides of the fixed sleeve are connected to racks, and the upper and lower sides of the exhaust pipe are connected to mounting blocks. Locking blocks are slidably connected to the mounting blocks, and pull rings are connected to the locking blocks. Guide rods are connected to both the front and rear parts of the pull rings. The guide rods are slidably connected to the adjacent mounting blocks, and elastic elements are connected between the guide rods and the connected mounting blocks.

[0010] Furthermore, a gripping groove is provided on the upper side of the pull ring.

[0011] Furthermore, the elastic element is a spring.

[0012] The beneficial effects are: when the exhaust gas from the car is discharged from the exhaust pipe and the bellows, the heat in the exhaust gas is conducted to the expansion ring, causing the expansion ring to expand and squeeze the elastic sleeve outward, so that the elastic sleeve presses the exhaust pipe tightly, thereby improving the stability of the bellows connection when the car is exhausting and preventing the bellows from loosening and falling off.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0019] A type of automotive exhaust bellows that facilitates a secure connection, such as Figures 1-4 As shown, it includes a bellows 1, a fixed sleeve 2, an elastic sleeve 3, an exhaust pipe 8, a sealing component, and a locking component. Fixed sleeves 2 are connected to both the left and right sides of the bellows 1. Elastic sleeves 3 are connected inside the fixed sleeves 2. Exhaust pipes 8 are snapped onto the fixed sleeves 2. A sealing component is provided on the bellows 1, and a locking component is provided on the fixed sleeves 2.

[0020] like Figure 2 and Figure 3 As shown, the sealing assembly includes a sealing cylinder 4, a sealing ring 5, and an expansion ring 6. The bellows 1 is connected to the sealing cylinder 4 on both the left and right sides. The sealing cylinder 4 is located inside the adjacent elastic sleeve 3. The sealing cylinder 4 is connected to the sealing ring 5 on the side of the sealing cylinder 4 that is far away from each other. The sealing cylinder 4 is connected to the expansion ring 6.

[0021] like Figure 1 and Figure 4 As shown, the locking assembly includes a rack 7, a mounting block 9, a locking block 10, a pull ring 11, a guide rod 12, and an elastic element. The rack 7 is connected to both the upper and lower sides of the fixing sleeve 2, and the mounting block 9 is connected to both the upper and lower sides of the exhaust pipe 8. The locking block 10 is slidably connected to each mounting block 9, and the pull ring 11 is connected to each locking block 10. The pull ring 11 has a gripping groove on its upper side for easy gripping. The guide rod 12 is connected to both the front and rear parts of the pull ring 11. The guide rod 12 is slidably connected to the adjacent mounting block 9. An elastic element, which is a spring 13, is connected between the guide rod 12 and the connected mounting block 9.

[0022] When using this utility model, first place the corrugated pipe 1 between the two exhaust pipes 8, then insert the exhaust pipe 8 between the fixed sleeve 2 and the elastic sleeve 3, and use the sealing cylinder 4 to limit and squeeze the elastic sleeve 3 so that the fixed sleeve 2 and the elastic sleeve 3 cooperate to clamp the exhaust pipe 8. At this time, the sealing ring 5 contacts the exhaust pipe 8, which enhances the sealing performance between the exhaust pipe 8 and the sealing cylinder 4.

[0023] When the exhaust pipe 8 is inserted between the fixed sleeve 2 and the elastic sleeve 3, the pull ring 11 is pulled outward first, which drives the guide rod 12 and the locking block 10 to move outward. The spring 13 is compressed and contracted, allowing the rack 7 to be inserted into the mounting block 9. Then the pull ring 11 is released, the spring 13 rebounds, and the pull ring 11, guide rod 12, and locking block 10 move downward to reset, thereby allowing the locking block 10 to engage with the rack 7, further fixing the exhaust pipe 8 and the fixed sleeve 2. When the vehicle exhaust gas is discharged from the exhaust pipe 8 and the bellows 1, the heat in the vehicle exhaust gas is conducted to the expansion ring 6, causing the expansion ring 6 to expand and squeeze the elastic sleeve 3 outward, thereby causing the elastic sleeve 3 to press the exhaust pipe 8 tightly. This improves the stability of the bellows 1 connection when the vehicle exhausts, preventing the bellows 1 from loosening and falling off.

[0024] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
