Description

Technical Field

[0001] The utility model relates to the technical field of silencer pipes, in particular to an adjustable assembled silencer pipe. Background Art

[0002] Exhaust noise is a common problem in modern industry and transportation. To reduce this noise pollution, mufflers have been widely used as an effective noise control device. Proper selection and use of mufflers can effectively reduce noise pollution and improve people's quality of life and environmental quality. Mufflers with different exhaust diameters have different noise reduction effects. However, existing mufflers typically have a fixed exhaust diameter, which to some extent limits their adaptability to different working conditions and noise environments, making them relatively inconvenient.

[0003] Therefore, a flexible adjustable assembled silencer tube has been developed that can adjust the exhaust diameter of the silencer tube to meet different silencer requirements in different usage scenarios. Utility Model Content

[0004] In order to overcome the disadvantage that the existing silencer usually has a fixed exhaust diameter, which to a certain extent limits its adaptability to different working conditions and noise environments and is relatively inconvenient, the utility model provides an adjustable assembled silencer that can adjust the exhaust diameter of the silencer to adapt to different silencer requirements in different usage scenarios and has strong flexibility.

[0005] The technical implementation plan of the present utility model is: an adjustable assembled silencer, including a silencer box, a mounting plate, an air inlet pipe, an air outlet pipe, a guide rod, a limiting frame and a first telescopic spring. A mounting plate is placed on the left part of the silencer box, the air inlet pipe is connected to the mounting plate, the air outlet pipe is clamped on the right part of the silencer box, the air outlet pipe is connected to the air inlet pipe, the left part of the silencer box is slidably connected to two groups of upper and lower guide rods, each group consists of two front and rear guide rods, the guide rods in the same group are slidably connected with limiting frames, the limiting frames are connected to the first telescopic spring, and the limiting frames are clamped with the mounting plate.

[0006] Optionally, a pulling handle is provided on the limiting frame.

[0007] Optionally, it also includes an installation pipe, a limiting ring, a second telescopic spring, a limiting ball and a connecting pipe. The installation pipe is connected to the outer side of the right part of the exhaust pipe. A limiting ring is slidably connected to the installation pipe. A second telescopic spring is connected between the limiting ring and the installation pipe. A plurality of limiting balls are rotatably clamped in the installation pipe. A connecting pipe is placed on the right part of the installation pipe, and the limiting balls are all clamped in conjunction with the connecting pipe.

[0008] Optionally, a plurality of placement holes are opened on the installation pipe, and the diameter of the placement holes is slightly smaller than that of the limiting ball.

[0009] Optionally, a plurality of limiting holes are opened on the connecting pipe.

[0010] Optionally, the connecting pipe is made of stainless steel.

[0011] The beneficial effect of the present invention is that the present invention pushes the limiting ring to move to the left, then pulls it outward from the connecting pipe, and then puts the connecting pipe to be replaced inside the installation pipe, so that the limiting ball clamps the connecting pipe, and then the limiting ring limits and fixes the limiting ball, thereby achieving the effect of being able to adjust the exhaust diameter of the silencer pipe to adapt to different silencer requirements in different usage scenarios, and having a strong flexibility.

[0016] The following description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0017] An adjustable assembled silencer pipe, such as Figure 1-Figure 3As shown, it includes a silencer box 1, a mounting plate 2, an air inlet pipe 3, an air outlet pipe 4, a guide rod 5, a limiting frame 6, a first telescopic spring 7, a mounting pipe 8, a limiting ring 9, a second telescopic spring 10, a limiting ball 11 and a connecting pipe 12. The mounting plate 2 is placed on the left side of the silencer box 1, and the air inlet pipe 3 is connected to the mounting plate 2. The air outlet pipe 4 is clamped on the right side of the silencer box 1, and the air outlet pipe 4 is connected to the air inlet pipe 3. The left side of the silencer box 1 is slidably connected to two groups of upper and lower guide rods 5, each group consists of two front and rear guide rods 5, and the guide rods 5 of the same group are slidably connected to the limiting frame 6, and the limiting frame 6 is connected to the first telescopic spring 7. 6 are all snap-fitted with the mounting plate 2, and a pulling handle is provided on the limiting frame 6 for easy pulling. The outer side of the right part of the outlet pipe 4 is connected to the mounting pipe 8, and a limiting ring 9 is slidably connected to the mounting pipe 8. A second telescopic spring 10 is connected between the limiting ring 9 and the mounting pipe 8. Six limiting balls 11 are rotatably snap-fitted in the mounting pipe 8, and a connecting pipe 12 is placed on the right part of the mounting pipe 8. The limiting balls 11 are all snap-fitted with the connecting pipe 12. Six placement holes are opened on the mounting pipe 8, and the aperture of the placement hole is slightly smaller than the limiting ball 11, which is convenient for snapping the limiting ball 11. Six limiting holes are opened on the connecting pipe 12, and the connecting pipe 12 is made of stainless steel.

[0018] When using the present invention, first move the device to the muffler installation position of the car, then pull the limiting frame 6 to slide upward on the guide rod 5, the first telescopic spring 7 is squeezed and contracted, and then the muffler box 1 is put on the intake pipe 3 and the outlet pipe 4, and then release the limiting frame 6. The first telescopic spring 7 rebounds, driving the limiting frame 6 to move downward, so that the limiting frame 6 is clamped with the mounting plate 2, thereby fixing and installing the muffler box 1. When the car is exhausting, the exhaust gas enters the outlet pipe 4 through the intake pipe 3, and is silenced inside the muffler box 1, and is then discharged through the mounting pipe 8 and the connecting pipe 12. When the connecting pipe 12 needs to be replaced, the limiting ring 9 can be pushed to move to the left so that the second telescopic spring 7 can be clamped. The spring 10 is squeezed and contracted, and then pulled outward toward the connecting pipe 12, pushing the limiting ball 11 to move upward, so that the connecting pipe 12 can be disassembled smoothly, and then the connecting pipe 12 that needs to be replaced is put inside the installation pipe 8, so that the limiting ball 11 clamps the connecting pipe 12, and then the limiting ring 9 is loosened, and the second telescopic spring 10 rebounds, driving the limiting ring 9 to reset, limiting and fixing the limiting ball 11, and fixing the connecting pipe 12 on the installation pipe 8, so that the connecting pipe 12 can be quickly replaced with different calibers to meet the needs of different occasions, thereby playing a role in being able to adjust the exhaust caliber of the silencer to meet the different silencer requirements in different usage scenarios, and having a strong flexibility.

[0019] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
