Description

Technical Field

[0001] This utility model relates to the field of exhaust pipes, specifically a high-temperature resistant exhaust pipe. Background Technology

[0002] Automotive exhaust bellows, also known as automotive exhaust hoses, are installed in the exhaust pipe between the engine exhaust manifold and the muffler, making the entire exhaust system flexible. This provides vibration and noise reduction, facilitates installation, and extends the lifespan of the exhaust muffler system. It is mainly used in light vehicles, microcars, and buses. Its structure consists of a double-layered bellows covered with a steel wire mesh sleeve, and straight-edge sections at both ends fitted with retaining rings. To improve the muffler effect, expansion joints or a mesh sleeve can be fitted inside the bellows.

[0003] For example, utility model publication (announcement number: CN209800070U) discloses a conveniently installed high-temperature resistant automotive exhaust pipe, including an exhaust pipe outer sleeve, a wire mesh layer fixedly installed on the inner wall of the outer sleeve, a heat insulation layer fixedly installed on the inner wall of the wire mesh layer, and an exhaust pipe inner sleeve fixedly installed on the inner wall of the heat insulation layer. This conveniently installed high-temperature resistant automotive exhaust pipe solves the problem that after prolonged use, a large amount of dirt accumulates inside the exhaust pipe, which, if not cleaned for a long time, can reduce vehicle performance or damage the exhaust pipe. However, the installation process of current exhaust pipes on the market is complicated, making it impossible for users to disassemble and clean the exhaust pipe themselves, requiring them to go to a repair shop for cleaning, increasing usage costs. Moreover, the heat insulation effect of current exhaust pipes on the market is not strong, which can easily cause the plastic parts around the exhaust pipe to melt, increasing fuel consumption, and causing the temperature inside the engine compartment to rise or burn the user.

[0004] The exhaust pipe of the above-mentioned utility model has a multi-layer structure, thereby improving the high temperature resistance of the exhaust pipe. However, its connection structure is fixed at the connection point by multiple spring structures. During the operation of the equipment, the mechanical vibration generated can easily cause the connection point to loosen and generate noise by increasing the amplitude of the springs.

[0006] The questions raised in the text.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a high-temperature resistant exhaust pipe, comprising an exhaust pipe body, wherein a muffler is provided on one side of the exhaust pipe body, and mounting components that are fixedly connected to the muffler are respectively fixedly connected to the top and bottom ends of the exhaust pipe body near the muffler.

[0008] Preferably, each of the mounting components includes a limiting block fixedly connected to one end of the exhaust pipe body, and a plurality of plug rods that are inserted and engaged with each limiting block are fixedly connected to the side of the muffler near the exhaust pipe body.

[0009] Preferably, the limiting block is fixedly connected to a positioning plate at the end away from the exhaust pipe body, and a connecting cylinder is fixedly connected to one side of the positioning plate.

[0010] Preferably, a sliding rod is slidably connected inside the connecting cylinder in the horizontal direction, and the connecting cylinder is elastically connected to one end of the sliding rod by a spring.

[0011] Preferably, an L-shaped mounting plate is fixedly connected to the end of the slide rod away from the connecting cylinder, and the bottom end of the L-shaped mounting plate slides in contact with the top end of the limiting block.

[0012] Preferably, the L-shaped mounting plate is threaded through with a fastening screw along the vertical direction, and the limiting block and the insert rod are respectively provided with screw holes that are threaded to the fastening screw.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] This invention inserts two rods on one side of the muffler into corresponding limiting blocks. By pushing each L-shaped mounting plate closer to the positioning plate, the threaded fastening screws on the L-shaped mounting plates align with the threaded holes of the limiting blocks and the rods. The fastening screws then fix the L-shaped mounting plates, rods, and limiting blocks, thus achieving a fixed connection between the exhaust pipe body and the muffler. Simultaneously, one end of the L-shaped mounting plate drives a sliding rod to slide along the inside of the connecting cylinder, compressing a spring. Through the spring's elasticity, during the threaded connection of the fastening screws, the spring applies a horizontal force to the L-shaped mounting plates, ensuring the fastening screws firmly abut against the L-shaped mounting plates and limiting blocks.

By pushing each L-shaped mounting plate 35 towards the positioning plate 32, the fastening screw 36 threaded onto the L-shaped mounting plate 35 aligns with the screw holes of the limiting block 31 and the insert rod 201. The fastening screw 36 then fixes the L-shaped mounting plate 35 and the insert rod 201 to the limiting block 31, thus achieving a fixed connection between the exhaust pipe body 1 and the muffler 2. Simultaneously, one end of the L-shaped mounting plate 35 drives the sliding rod 34 to slide along the inside of the connecting cylinder 33, compressing the spring. Through the spring force, during the threaded connection of the fastening screw 36, the spring applies a horizontal force to the L-shaped mounting plate 35, allowing the fastening screw 36 to tightly abut against the L-shaped mounting plate 35, the limiting block 31, and the insert rod 201. Inside the screw hole, avoid loosening of the connection due to mechanical vibration.
