Description

Technical Field

[0001] The utility model relates to the technical field of mufflers, in particular to a gasket and a muffler. Background Art

[0002] At present, the muffler is a key component to reduce the exhaust noise of automobile engines. It eliminates noise by reducing and attenuating the exhaust pulsation pressure.

[0003] The muffler is installed at the bottom of the car and fixed by bolts. The traditional muffler generates vibration noise when working, which affects the user experience. In China's authorized patent No. 201520065754.5, a car exhaust muffler lacks a gasket mechanism when installed and used, resulting in the vibration of the muffler being directly transmitted to the bottom of the car body during use, causing noise to be generated, which leads to inconvenience in use. In addition, the existing gasket only blocks the installation location and cannot block the muffler as a whole, so a gasket mechanism is needed to solve the above problems. Therefore, we propose a gasket and a muffler. Utility Model Content

[0004] In view of the problems existing in the above-mentioned existing gaskets and mufflers, the present utility model is proposed.

[0005] Therefore, the purpose of the utility model is to provide a gasket and a silencer, by arranging multiple groups of elastic gaskets at the bottom end of the bracket. During the installation of the silencer, the multiple groups of elastic gaskets will be completely fitted on the top of the silencer body, thereby reducing the vibration generated by the silencer during use, greatly improving the noise generated when the silencer is used, and solving the problems of the gasket and the silencer.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A gasket and a silencer, comprising a bracket, welding plates are fixed on both sides of the top of the bracket, a pressure slide bar is provided at the top of the bracket, a plurality of pressure slide bars are evenly distributed and installed, the bottom end of the pressure slide bar passes through the interior of the bracket, and a gasket is fixed to the bottom end of the bracket, a pressure spring is sleeved on the outer wall of the pressure slide bar, docking blocks are fixed to the four corners of the outer wall of the bracket, the top of the silencer body is provided at the bottom end of the gasket, an exhaust pipe is provided on the front side of the silencer body, and mounting blocks are fixed to the four corners of the silencer body.

[0008] Preferably, one end of the pressure spring is fixed to the top of the gasket, and the other end of the pressure spring is fixed to the bottom end of the bracket to ensure a tight fit on the top of the muffler.

[0009] Preferably, the bottom end of the gasket is attached to the top of the muffler body, and the gasket is made of rubber to absorb the noise generated by the muffler.

[0010] Preferably, the pressure slide rod is adapted to be connected with the penetration point of the bracket, and the penetration point of the pressure slide rod and the bracket constitutes a sliding mechanism, and a limiting plate is fixed on the top end of the pressure slide rod to ensure the tightness of the gasket joint.

[0011] Preferably, a bolt through hole is provided inside the mounting block, a threaded mounting groove is provided inside the docking block, the bolt through hole is located directly below the threaded mounting groove, and a mounting bolt is externally connected to the inside of the bolt through hole, so as to quickly install the muffler.

[0012] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0013] 1. The utility model arranges multiple sets of elastic gaskets at the bottom end of the bracket. During the installation of the muffler, the multiple sets of elastic gaskets will completely fit on the top of the muffler body, thereby reducing the vibration generated by the muffler during use and greatly improving the noise generated when the muffler is used.

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] The utility model embodiment discloses a gasket and a muffler.

[0023] The utility model provides Figure 1-3 A gasket and muffler shown include a bracket 1, welding plates 6 are fixed on both sides of the top of the bracket 1, a pressure slide bar 4 is arranged at the top of the bracket 1, and a plurality of pressure slide bars 4 are evenly distributed and installed, the bottom end of the pressure slide bar 4 passes through the interior of the bracket 1, and a gasket 11 is fixed to the bottom end of the bracket 1, a pressure spring 10 is sleeved on the outer wall of the pressure slide bar 4, docking blocks 2 are fixed to the four corners of the outer wall of the bracket 1, the top of the muffler body 7 is arranged at the bottom end of the gasket 11, an exhaust pipe 12 is arranged on the front side of the muffler body 7, and mounting blocks 8 are fixed to the four corners of the muffler body 7, and a plurality of groups of elastic gaskets 11 are arranged through the bottom end of the bracket 1. During the installation of the muffler, the plurality of groups of elastic gaskets 11 will be completely fitted on the top of the muffler body 7, thereby reducing the vibration generated by the muffler during use and greatly improving the noise generated when the muffler is in use.

[0024] To ensure that the gasket fits evenly on the top of the muffler: Figure 1 and Figure 2 As shown, one end of the pressure spring 10 is fixed to the top of the gasket 11, and the other end of the pressure spring 10 is fixed to the bottom end of the bracket 1. The pressure spring 10 will give elasticity to the gasket 11 at the bottom end of the pressure slide rod 4, so that the gasket 11 fits tightly on the top of the muffler body 7.

[0025] To reduce the noise generated by the muffler: Figure 1 and Figure 2 As shown, the bottom end of the gasket 11 is attached to the top of the muffler body 7. The gasket 11 is made of rubber. When the gasket 11 contacts the muffler body 7, it will absorb a large amount of vibration generated by the muffler body 7 and reduce the generation of noise.

[0026] In order to ensure the stability of the gasket and the muffler when in contact: Figure 1 and Figure 2As shown, the pressure slide bar 4 is adapted to be connected with the penetration point of the bracket 1, and the pressure slide bar 4 and the penetration point of the bracket 1 form a sliding mechanism, a limiting plate 5 is fixed at the top end of the pressure slide bar 4, the pressure slide bar 4 and the bracket 1 are adapted to be connected, and a sliding mechanism is formed, which will ensure the stability of the pressure slide bar 4 when sliding up and down.

[0027] To install the silencer: Figure 1 , Figure 2 and Figure 3 As shown, a bolt through hole 9 is provided inside the mounting block 8, a threaded mounting groove 3 is provided inside the docking block 2, the bolt through hole 9 is located directly below the threaded mounting groove 3, and a mounting bolt is externally connected to the bolt through hole 9. When installing the muffler, the external bolt is directly inserted into the bolt through hole 9 and docked with the threaded mounting groove 3 to complete the quick docking installation of the muffler body 7.

[0028] During operation, the welding plate 6 installs the bracket 1 on the bottom of the car. At this time, the bracket 1 will be fixed in advance. During the installation of the muffler body 7, the top of the muffler body 7 will fit on the bottom of the multiple groups of gaskets 11. The gasket 11 is provided with a bottom end of the pressing slide bar 4. The pressing slide bar 4 is provided with a pressing spring 10. The pressing spring 10 will give the gasket 11 elasticity so that the bottom end of the gasket 11 can fit on the irregular part of the top of the muffler body 7, thereby ensuring the stability of the muffler body 7 during installation. The external bolt is inserted into the bolt through hole 9 opened in the mounting block 8, and the top end of the external bolt will enter the threaded mounting groove 3 opened in the docking block 2. At this time, when the external bolt is rotated, the muffler body 7 will be tightened to the bottom end of the bracket 1, thereby forming a quick installation of the muffler body 7. The design is simple and more practical.
