[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0037] The limiting component 10 of the embodiment of the present utility model includes: an elastic component 2, a mounting plate 1, a limiting column 3 and a guide arm 4, the mounting plate 1 is detachably connected to the muffler, the limiting column 3 is arranged on the mounting plate 1, one end of the elastic component 2 is rotatably connected to the limiting column 3, the guide arm 4 is rotatably arranged on the mounting plate 1, one end of the guide arm 4 is rotatably connected to the end of the elastic component 2 away from the limiting column 3, and the other end of the guide arm 4 is in contact with the silencer cotton 30, wherein the elastic component 2 is suitable for providing elastic force to enable the guide arm 4 to press the silencer cotton 30.

[0038] Specifically, if Figures 1 to 3 As shown, the mounting plate 1 is detachably connected to the muffler. For example, the mounting plate 1 is connected to the internal ventilation channel of the muffler through a thread.

[0039] The limiting column 3 is set on the mounting plate 1, and the limiting column 3 is detachably connected to the mounting plate 1. The elastic component 2 can be a spring 201, for example, a hook spring 201, and a first hook 202 and a second hook 203 are set on both sides of the spring 201. The first hook 202 is set on the limiting column 3 so that the spring 201 can rotate relative to the limiting column 3, and the second hook 203 is sleeved on the guide arm 4, so that the spring 201 can rotate relative to the guide arm 4. The spring 201 causes the guide arm 4 to rotate counterclockwise to compress the silencer cotton 30, and then fix the silencer cotton 30 in the muffler. When disassembling, the guide arm 4 is rotated clockwise to move the guide arm 4 away from the silencer cotton 30, so that the silencer cotton 30 can be removed from the silencer, and the silencer cotton 30 can be replaced and fixed. There is no need to replace the entire silencer, thereby reducing operating costs.

[0040] Furthermore, the silencer cotton 30 can be rectangular, such as sheet-shaped. There are multiple silencer cottons 30 in the silencer, and multiple silencer cottons 30 are arranged in the silencer. A single silencer cotton 30 can be replaced individually by rotating the guide arm 4.

[0041] The limiting component 10 of the embodiment of the present invention facilitates the replacement and fixation of the silencer cotton 30 in the silencer, thereby reducing operating costs. Furthermore, the silencer cotton 30 in the silencer can be replaced individually by rotating the guide arm 4.

[0042] In some embodiments, a plurality of mounting holes 103 are provided in the circumferential direction of a side of the mounting plate 1 away from the guide arm 4 for mounting the limiting post 3, with one end of the limiting post 3 being mounted in any one of the mounting holes 103. The plurality of mounting holes 103 are arranged in a spaced-apart arrangement in the vertical direction. By arranging the limiting post 3 in different mounting holes 103 and at different positions of the mounting plate 1 while keeping the position of the guide arm 4 on the mounting plate 1 unchanged, the elastic component 2 can be stretched to different degrees, so that the elastic component provides different elastic forces to fix the sound-absorbing cotton 30, or the guide arm 4 can be rotated to different angles to fix the sound-absorbing cotton 30.

[0043] In some embodiments, the limiting component 10 further includes a guide wheel 5 , which is rotatably disposed at one end of the guide arm 4 away from the elastic component 2 , and an anti-slip pattern is provided on the outer circumference of the guide wheel 5 .

[0044] Specifically, if Figures 1 to 3 As shown, the guide wheel 5 is rotatable relative to the guide arm 4, and the guide wheel 5 is suitable for contacting the silencer cotton 30.

By providing the guide wheel 5, the wear of the silencer cotton 30 during installation and disassembly is reduced, and the stability and safety of the limiting use are improved.

[0045] In some embodiments, the position-limiting component 10 further includes a guide rim 51, which is sleeved on the outer circumference of the guide wheel 5. The guide rim 51 is made of the same material as the muffler pad 30 to prevent a decrease in the muffler effect due to the position-limiting component 10, to prevent direct contact between the guide wheel 5 and the muffler pad 30, which could cause wear during removal, and to improve the stability of the muffler pad 30 during use.

[0046] In some embodiments, the limiting component 10 further includes a limiting cylinder 8 , which is disposed on the main body of the mounting plate 1 , and the limiting cylinder 8 is disposed on a side adjacent to the guide wheel 5 .

[0047] Specifically, if Figures 1 to 3 As shown, the limiting cylinder 8 is arranged on a side of the limiting cylinder 8 adjacent to the guide wheel 5. For example, by setting the limiting cylinder 8, the clockwise rotation of the guide arm 4 during disassembly or installation can be avoided to cause excessive stretching of the elastic component 2, thereby improving the stability and safety of the elastic component 2.

[0048] In some embodiments, the guide arm 4 includes a guide arm body 401 and a rotating shaft 402 . The rotating shaft 402 is disposed on the mounting plate 1 , and the guide arm body 401 is rotatably sleeved on the rotating shaft 402 .

[0049] Specifically, if Figures 1 to 3 As shown, the guide arm body 401 is disposed on the rotating shaft 402, and the guide arm body 401 is rotatable relative to the rotating shaft 402, thereby facilitating the elastic component 2 to provide elastic force to make the guide arm body 401 have a tendency to rotate counterclockwise.

[0050] Furthermore, a coil spring is provided on the rotating shaft 402 , and the coil spring is connected to the mounting plate 1 and the guide arm 4 so that the guide arm body 401 has a tendency to rotate counterclockwise, thereby facilitating the rotation of the guide arm body 401 to fix the silencer cotton 30 .

[0051] Furthermore, a connecting column 403 is provided on one side of the guide arm body 401 adjacent to the elastic component 2. When the elastic component 2 is a spring 201, the second belt hook 203 of the spring 201 is sleeved on the connecting column 403 on the guide arm body 401, thereby allowing the spring 201 to rotate relative to the guide arm body 401 during the rotation of the guide arm 4.

[0052] In some embodiments, the mounting plate 1 includes a plate body 101 and a connecting member 102 . The connecting member 102 is threadedly connected to the plate body 101 , and the connecting member 102 passes through the plate body 101 and is connected to the muffler.

The number of connecting members 102 can be multiple. Multiple connecting members 102 fix the plate body 101 of the mounting plate 1 on the muffler, which can improve the stability of the mounting plate 1 fixed on the muffler.

[0054] The silencer of an embodiment of the present utility model includes: a limiting component 10, a silencer body 20 and a silencer cotton 30. The silencer body 20 is provided with an installation channel, and the silencer cotton 30 is arranged in the installation channel. The limiting component 10 is any one of the limiting components 10 described above. The limiting component 10 is detachably arranged in the installation channel, and the limiting component 10 is in contact with the silencer cotton 30.

[0055] Specifically, if Figures 1 to 3 As shown, a mounting channel for the silencer cotton 30 is provided in the muffler body 20 , and the mounting channel can be used for ventilation to reduce the noise of the ventilation device during ventilation. The limiting component 10 is used to fix the silencer cotton 30 .

[0056] The silencer of the embodiment of the present utility model facilitates the replacement and fixation of the silencer cotton 30, thereby reducing the operating cost.

[0057] Furthermore, there are multiple limiting components 10, and the muffler's mounting channel is provided with multiple threaded holes.
