Description

Technical Field

[0001] This utility model relates to the field of silencer technology, and in particular to a quick installation device for a silencer transition pipe. Background Technology

[0002] In the exhaust systems of modern machinery and vehicles, the muffler is an indispensable key component. Its main function is to reduce exhaust noise, thereby minimizing noise pollution to the environment and human health, while ensuring the smooth operation of the exhaust system. The connection quality between the muffler's transition pipe and the exhaust pipe directly affects the muffler's performance and service life.

[0003] Currently, the traditional connection methods between the transition pipe and the exhaust pipe of the silencer are mostly flange connection and welding. Flange connection requires multiple bolts for fixing, which is cumbersome, time-consuming and requires high installation accuracy. Inconsistent bolt tightness can easily lead to air leakage at the connection.

[0004] Although welding provides a strong connection, it is a permanent connection that is difficult to disassemble once installed, which is not conducive to later maintenance, repair and replacement of parts. Furthermore, the welding process is prone to deformation, which affects the overall performance of the muffler. In addition, traditional connection methods are prone to a decrease in sealing performance when dealing with vibrations and thermal expansion and contraction generated during the operation of the muffler, which can lead to gas leakage and reduce the muffler effect.

[0005] Therefore, developing a muffler transition pipe installation device that can achieve rapid installation and convenient disassembly while ensuring good sealing performance and stability has become an urgent problem to be solved in the industry. Utility Model Content

[0006] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a quick installation device for a muffler transition pipe that can solve the above problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a muffler transition pipe quick installation device, including a muffler housing, a clamp arm one and a clamp arm two, an exhaust tailpipe fixedly connected to the top of the muffler housing, a muffler transition pipe fixedly connected to the bottom of the muffler housing, and an exhaust pipe provided below the muffler transition pipe.

[0008] Hoop arm one and hoop arm two are installed on the muffler transition pipe;

[0009] Both hoop arm one and hoop arm two are fixedly connected to one side with a first connecting ear, and a rotating shaft is fixedly installed on each of the first connecting ears. Hinges are provided on the two rotating shafts.

[0010] The other end of both hoop arm one and hoop arm two is fixedly connected to a second connecting lug. A fixed shaft is rotatably connected to the second connecting lug on hoop arm one. A bolt is fixedly installed on the fixed shaft, and a fastening nut is threaded onto the bolt.

[0011] Preferably, the first hoop and the second hoop are each half-rings.

[0012] Preferably, a gasket and a rubber ring are movably installed between the muffler transition pipe and the exhaust pipe.

[0013] Preferably, the second connecting lug on the second hoop arm is a transverse n-shaped lug with a bolt passing through it, and a fastening nut located on the outside of the second hoop arm and in close contact with its surface.

[0014] Preferably, the diameter of the fastening nut is larger than the inner diameter of the second clamp arm.

[0015] Preferably, the two rotating shafts are movably connected by a hinge.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) The muffler transition pipe quick installation device, by tightening the fastening nut, makes it fit tightly against the surface of the second hoop. Since the diameter of the fastening nut is larger than the inner diameter of the second hoop, as the fastening nut is tightened, an inward pulling force is generated, causing the first and second hoops to tighten, thereby applying pressure to the muffler transition pipe and the exhaust pipe, making the connection between the two tighter. At the same time, the rubber ring undergoes elastic deformation under pressure, filling the gap at the connection, further enhancing the sealing effect and ensuring that gas will not leak from the connection. When disassembling, simply loosen the fastening nut in the reverse direction, pull the bolt out from the second connecting ear of the second hoop, and use the movable connection characteristics of the hinge to open the first and second hoops. The operation is simple and quick, realizing the function of quick installation and disassembly.

[0018] (2) The muffler transition pipe quick installation device, the gasket and rubber ring play a sealing and buffering role to prevent gas leakage, and at the same time reduce vibration and wear at the connection. Then, the muffler transition pipe with the gasket and rubber ring is aligned with the air outlet pipe so that the two pipe openings fit together. Attached Figure Description

[0030] Please see Figure 1-5 This utility model provides a technical solution: a quick installation device for a muffler transition pipe, including a muffler housing 5, a hoop arm 1 7 and a hoop arm 2 8;

[0031] An exhaust tailpipe 6 is fixedly connected to the top of the muffler housing 5, and a muffler transition pipe 1 is fixedly connected to the bottom of the muffler housing 5. An exhaust pipe 4 is provided below the muffler transition pipe 1.

[0032] Hoop arm 7 and hoop arm 8 are installed on the muffler transition pipe 1, and hoop arm 7 and hoop arm 8 are each half-ring;

[0033] A gasket 2 and a rubber ring 3 are movably installed between the muffler transition pipe 1 and the exhaust pipe 4;

[0034] Gasket 2 and rubber ring 3 serve to seal and buffer, preventing gas leakage and reducing vibration and wear at the connection. Then, the muffler transition pipe 1 with gasket 2 and rubber ring 3 fitted on it is aligned with the air outlet pipe 4 so that the two pipe openings fit together.

[0035] Both hoop arm 7 and hoop arm 8 are fixedly connected to one side with a first connecting ear 14. A rotating shaft 12 is fixedly installed on the first connecting ear 14. A hinge 13 is provided on the two rotating shafts 12, and the two rotating shafts 12 are movably connected through the hinge 13.

[0036] The other end of both hoop arm 7 and hoop arm 8 is fixedly connected to a second connecting lug 15. A fixed shaft 9 is rotatably connected to the second connecting lug 15 on hoop arm 7. A bolt 10 is fixedly installed on the fixed shaft 9. A fastening nut 11 is threaded onto the bolt 10.

[0037] The second connecting lug 15 on the second hoist arm 8 is a transverse n-shaped lug, with the bolt 10 passing through its interior and the fastening nut 11 located on the outside of the second hoist arm 8 and tightly fitting its surface.

[0038] The diameter of the fastening nut 11 is larger than the inner diameter of the hoop arm 8;

[0039] Working principle: The muffler transition pipe quick installation device provided by this utility model works on the basis of the coordinated operation of each component to achieve a quick and stable connection between the muffler transition pipe and the exhaust pipe.

[0040] First, during the installation preparation stage, the gasket 2 and rubber ring 3 are sequentially placed under the muffler transition pipe 1. The gasket 2 and rubber ring 3 play a sealing and buffering role to prevent gas leakage and reduce vibration and wear at the connection. Then, the muffler transition pipe 1 with the gasket 2 and rubber ring 3 in place is aligned with the air outlet pipe 4 so that the pipe openings of the two are in contact.

[0041] Next, we proceed to the connection operation. Hoop arm 7 and hoop arm 8 are each half-rings, connected by hinge 13. This design facilitates opening and closing. During installation, hoop arm 7 and hoop arm 8 are wrapped around the connection between the muffler transition pipe 1 and the exhaust pipe 4 to ensure a tight fit. Then, rotate the fixed shaft 9 on hoop arm 7, which is rotatably connected to the second connecting ear 15, to drive the bolt 10 on the fixed shaft 9 through the transverse n-shaped second connecting ear 15 on hoop arm 8, and tighten the fastening nut 11 onto the bolt 10.

[0042] During the tightening process, by tightening the fastening nut 11, it is made to fit tightly against the surface of the second hoop 8. Since the diameter of the fastening nut 11 is larger than the inner diameter of the second hoop 8, as the fastening nut 11 is tightened, an inward pulling force is generated, which causes the first hoop 7 and the second hoop 8 to tighten, thereby applying pressure to the muffler transition pipe 1 and the exhaust pipe 4, making the connection between the two tighter. At the same time, the rubber ring 3 undergoes elastic deformation under pressure, filling the gap at the connection, further enhancing the sealing effect, and ensuring that gas will not leak from the connection.

[0043] During disassembly, simply loosen the fastening nut 11 in the reverse direction, pull the bolt 10 out of the second connecting lug 15 of the second hoop arm 8, and use the movable connection characteristic of the hinge 13 to open the first hoop arm 7 and the second hoop arm 8. The operation is simple and quick, realizing the function of rapid installation and disassembly.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
