[0026] Example 1:

[0027] Reference Figures 1-4 A noise-reducing muffler that is easy to connect includes a noise-reducing muffler body 1 and a connecting assembly 2. An air inlet pipe 3 and an air outlet pipe 4 are respectively connected to both sides of the noise-reducing muffler body 1. The other end of each air inlet pipe 3 is connected to a connecting pipe 5 via the connecting assembly 2. The connecting assembly 2 includes a base 201, an adjusting assembly 6 is provided inside the base 201, a first retaining ring 202 is fixedly connected to the left side of the top of the base 201, and a second retaining ring 203, which is used with the first retaining ring 202, is provided on the right side of the top of the base 201. Rubber pads 204 are provided inside the first retaining ring 202 and the second retaining ring 203, which can be used to connect the air inlet pipe 3 of the noise-reducing muffler body 1. The device allows for quick connection to the external connecting pipe 5. The rubber pad 204 enhances the seal during installation, preventing leakage at the connection point between the air intake pipe 3 and the connecting pipe 5. The inner cavity of the base 201 contains an adjustment assembly 6, which includes a handle 601. The inner cavity of the base 201 contains a threaded rod 602, with a threaded sleeve 603 threadedly connected to its surface. The top of the threaded sleeve 603 is fixedly connected to the second retaining ring 203, and the right side of the threaded rod 602 is fixedly connected to the handle 601. This allows the second retaining ring 203 to move and cooperate with the first retaining ring 202 for quick connection and installation of the noise reduction muffler.

[0028] Example 2:

[0029] Reference Figure 2 , Figure 3 and Figure 4 The first retaining ring 202 and the second retaining ring 203 are provided with a snap-fit ​​assembly 7 at their top. The snap-fit ​​assembly 7 includes a connecting block 701 fixedly installed on the top right side of the first retaining ring 202. The top left side of the second retaining ring 203 has a connecting groove 702 that mates with the connecting block 701. The top of the connecting groove 702 has a movable groove 703. The inner cavity of the movable groove 703 is provided with a locking block 704. The top of the connecting block 701 has a locking groove 705 that mates with the locking block 704. The top of the locking block 704 is fixedly connected to a movable rod 706. The top of the movable rod 706 is fixedly connected to a pull handle 707. A spring 708 is sleeved on the surface of the movable rod 706, which can engage the first retaining ring 202. The engagement of the first retaining ring 202 and the second retaining ring 203 increases the stability of the connection between the first retaining ring 202 and the second retaining ring 203. A sliding groove 8 is provided at the bottom of the inner cavity of the base 201. A slider 9 is slidably connected to the inner cavity of the sliding groove 8. The top of the slider 9 is fixedly connected to the threaded sleeve 603, which can limit and guide the movement of the threaded sleeve 603, increasing the stability when the threaded rod 602 drives the threaded sleeve 603 to move. Limiting grooves 10 are provided on both sides of the inner cavity of the movable groove 703. A limiting block 11 is slidably connected to the inner cavity of the limiting groove 10. The end of the limiting block 11 away from the limiting groove 10 is fixedly connected to the locking block 704, which can increase the stability of the locking block 704 when it engages and moves.

[0030] The working principle is as follows:

[0031] In use, connect the intake pipe 3 to the external connecting pipe 5, and then place the joint between the intake pipe 3 and the connecting pipe 5 between the first retaining ring 202 and the second retaining ring 203. Then, rotate the handle 601 to drive the threaded rod 602 to rotate. The threaded rod 602 drives the threaded sleeve 603 to move to the left. The threaded sleeve 603 can drive the second retaining ring 203 to move to the left. At this time, in cooperation with the first retaining ring 202, the joint between the intake pipe 3 and the connecting pipe 5 can be wrapped. At the same time, the rubber gasket 204 can increase the sealing when wrapping and prevent leakage at the joint between the intake pipe 3 and the connecting pipe 5.

[0032] Simultaneously, when the first retaining ring 202 and the second retaining ring 203 are connected, the connecting block 701 will enter the connecting groove 702, and then enter the retaining groove 705 through the retaining block 704. This can increase the stability when the first retaining ring 202 and the second retaining ring 203 are connected. The above operation does not require aligning the fixing hole on the muffler with the mounting hole on the pipe during connection, and then passing the threaded bolt through the fixing hole and nut for connection. At the same time, no special tools are required for connection, which improves the convenience of operation.

[0033] In summary, this easy-to-connect noise reduction muffler, through the connection component 2, allows for quick connection of the air inlet pipe 3 of the muffler body 1 to the external connecting pipe 5. The adjustment component 6 moves the second retaining ring 203, which engages with the first retaining ring 202, enabling rapid connection and installation of the muffler. Finally, the snap-fit ​​component 7 secures the first retaining ring 202 and the second retaining ring 203, increasing the stability of the connection. This eliminates the need to align the fixing holes on the muffler with the mounting holes on the pipe during connection, and to pass the threaded bolt through the fixing holes and nut for connection. Furthermore, it eliminates the need for special tools, improving operational convenience.
