[0001] This utility model relates to the field of silencer technology, and in particular to a noise reduction structure and a silencer having the noise reduction structure. Background Technology
[0002] Noise reduction structures generally refer to structures used to reduce the impact of noise on people. Silencers are one type of noise reduction structure. They can reduce noise from entering a specific area by blocking the propagation path of sound waves. This device plays an important role in many fields.
[0003] During long-term use, dust can accumulate on the galvanized mesh of existing silencers. To improve noise reduction, regular cleaning of the device is necessary. However, the screw-fixing method can easily lead to screw loss, affecting the subsequent normal installation of the silencer. Therefore, a noise reduction structure and a silencer with this structure are needed to connect the fixed structures together and prevent parts from being lost. Utility Model Content
[0004] The purpose of this utility model is to provide a noise reduction structure and a muffler having the noise reduction structure, so as to solve the problem mentioned in the background art, that in the long-term use of existing mufflers, dust will accumulate on the outside of the galvanized mesh. In order to improve the noise reduction effect, the device needs to be cleaned regularly. However, the screw fixing method is prone to screw loss, which affects the subsequent normal installation of the muffler.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] A noise reduction structure includes a noise reduction component, which includes a top cover, a bottom cover, a galvanized mesh, sound insulation paper, and sound-absorbing cotton. The outer surfaces of the top cover and the bottom cover are fixed to the outer surfaces of the outer connecting plate and the inner connecting plate, respectively. The outer surface of the bottom cover is fixed to the outer surface of the fixing frame. The galvanized mesh is located between the top cover and the bottom cover, and two sets of galvanized mesh are provided. The sound insulation paper and the sound-absorbing cotton are located between the two sets of galvanized mesh, and the sound-absorbing cotton is wrapped inside the sound insulation paper.
[0007] This utility model also provides a muffler with the aforementioned noise reduction structure, including a disassembly assembly. The disassembly assembly includes an outer connecting plate, an inner connecting plate, a mounting groove, a connecting rod, and a connecting block. The outer connecting plate is located inside the inner connecting plate, the mounting groove is opened inside the outer connecting plate, the connecting rod passes through and is connected inside the outer connecting plate, and the connecting block is fixed to the outer surface of the connecting rod, located inside the inner connecting plate. It also includes a reinforcement assembly, which includes a fixed frame, a movable groove, a limiting post, and a guide post. The movable groove is opened inside one side of the fixed frame, the limiting post is movably connected to the inside of the fixed frame, and the guide post is fixed to the outer surface of the top of the limiting post, located inside the movable groove.
[0008] Furthermore, a connecting hole is provided inside the connecting rod, and a limit rod is inserted into the connecting hole located at the outer connecting plate.
[0009] Furthermore, a guide plate is fixed to the outer surface of the limiting rod, and a spring is fixed to the bottom surface of the guide plate, with the spring fixed inside the outer connecting plate.
[0010] Furthermore, a fixing plate is fixed to one side of the outer surface of the bottom end of the fixing frame, and a threaded post is threadedly connected to the fixing plate and the guide post, and a fixing post is fixed to the outer surface of the threaded post.
[0011] Compared with existing technologies, the advantages of this utility model are:
[0012] I. This utility model, through its designed disassembly and assembly components, allows for the following process: When cleaning the galvanized mesh, a pulling force is applied to the guide plate, causing the limiting rod to disengage from the inner connecting plate. A pulling force is then applied to the connecting rod, causing the connecting block to move into the mounting groove. Once the force applied to the guide plate is released, the limiting rod springs back into the inner connecting plate and connecting rod under the elastic force of the spring, thus disengaging the connection between the outer and inner connecting plates. The top and bottom covers can then be disassembled without restriction. This design connects the fixed structures together, preventing the loss of parts.
[0013] Second, with the cooperation of the reinforcement components, this utility model first drills corresponding holes at the positions that need to be fixed. After installing the device in the required position, a downward force is applied to the guide post, causing the limiting post to move to the bottom of the fixed frame. Then, a rotational force is applied to the fixed post, causing the threaded post to rotate into the guide post. The guide post is then fixed at the bottom of the movable groove. This solution can more stably fix the device in the required position. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0026] Please see Figures 1-3 This embodiment is a noise reduction structure and a silencer having the noise reduction structure, including:
[0027] The assembly and disassembly components include an outer connecting plate 21, an inner connecting plate 22, a mounting groove 23, a connecting rod 24, and a connecting block 25. The outer connecting plate 21 is located inside the inner connecting plate 22, the mounting groove 23 is opened inside the outer connecting plate 21, the connecting rod 24 passes through and is connected to the inside of the outer connecting plate 21, and the connecting block 25 is fixed to the outer surface of the connecting rod 24 and is located inside the inner connecting plate 22.
[0028] By connecting the outer connecting plate 21 and the inner connecting plate 22, the top cover 11 and the bottom cover 12 are fixed in the required position. The mounting groove 23 is used to receive and install the connecting block 25, and then the connecting block 25 is stored inside the outer connecting plate 21. The connecting rod 24 is used to connect the outer connecting plate 21 and the inner connecting plate 22 together.
[0029] A connecting hole 26 is provided inside the connecting rod 24, and a limit rod 27 is inserted into the connecting hole 26 located on the outer connecting plate 21.
[0030] The connecting hole 26 is used to receive and install the limiting rod 27, thereby fixing the connecting block 25 in different positions. The limiting rod 27 is used to fix the connecting rod 24 inside the outer connecting plate 21.
[0031] A guide plate 28 is fixed to the outer surface of the limiting rod 27, and a spring 29 is fixed to the bottom surface of the guide plate 28. The spring 29 is fixed inside the outer connecting plate 21.
[0032] The guide plate 28 facilitates the application of pulling force to the limiting rod 27, while the spring 29 is used to quickly spring the limiting rod 27 back to the desired position.
[0033] The noise reduction assembly includes a top cover 11, a bottom cover 12, a galvanized mesh 13, sound insulation paper 14, and sound-absorbing cotton 15. The outer surfaces of the top cover 11 and the bottom cover 12 are fixed to the outer surfaces of the outer connecting plate 21 and the inner connecting plate 22, and the outer surface of the bottom cover 12 is fixed to the outer surface of the fixing frame 31. The galvanized mesh 13 is located between the top cover 11 and the bottom cover 12. There are two sets of galvanized mesh 13. The sound insulation paper 14 and the sound-absorbing cotton 15 are located between the two sets of galvanized mesh 13. The sound-absorbing cotton 15 is wrapped inside the sound insulation paper 14.
[0034] The top cover 11 and the bottom cover 12 are used to seal the space at both ends of the galvanized wire mesh 13. The galvanized wire mesh 13 is used to initially filter and reflect sound, reducing noise transmission. The sound insulation paper 14 further absorbs and isolates sound, while the sound-absorbing cotton 15 provides additional sound absorption and reduces noise levels.
[0035] Working principle: When the galvanized wire mesh 13 needs to be cleaned, a pulling force is applied to the guide plate 28, which causes the limiting rod 27 to disengage from the outer connecting plate 21. A pulling force is applied to the connecting rod 24, which causes the connecting block 25 to move into the mounting groove 23. The force applied to the guide plate 28 is released. Under the elastic force of the spring 29, the limiting rod 27 springs back into the outer connecting plate 21 and the connecting rod 24, thus canceling the connection between the outer connecting plate 21 and the inner connecting plate 22. The top cover 11 and the bottom cover 12 can then be disassembled after they are no longer restricted.
[0036] This step connects the fixed structures together to prevent parts from being lost.
[0037] Please see Figure 1 , Figure 2 and Figure 4As shown, this embodiment is based on the above embodiment and further includes a reinforcing component. The reinforcing component includes a fixed frame 31, a movable groove 32, a limiting post 33, and a guide post 34. The movable groove 32 is opened inside one side of the fixed frame 31, the limiting post 33 is movably connected to the inside of the fixed frame 31, and the guide post 34 is fixed to the outer surface of the top of the limiting post 33 and is located inside the movable groove 32.
[0038] A fixing plate 35 is fixed to one outer surface of the bottom end of the fixing frame 31. The fixing plate 35 and the guide post 34 are internally threaded with a threaded post 36. A fixing post 37 is fixed to the outer surface of the threaded post 36.
[0039] The fixed frame 31 is used for the movement of the limiting post 33 within it, the movable groove 32 is used for the movement of the guide post 34 within it, the limiting post 33 is used to stably fix the device in the required position, the guide post 34 facilitates changing the position of the limiting post 33, the fixed plate 35 is used for the horizontal movement of the threaded post 36 within it, the threaded post 36 is used to fix the guide post 34 in the required position, and the fixed post 37 facilitates applying rotational force to the threaded post 36.
[0040] Working principle: First, drill the corresponding holes at the position to be fixed. After installing the device at the required position, apply a downward force to the guide post 34 to move the limiting post 33 to the bottom of the fixed frame 31. Then apply a rotational force to the fixed post 37 to rotate the threaded post 36 into the guide post 34 and fix the guide post 34 to the bottom of the movable groove 32.
[0041] This step allows the device to be more securely fixed in the desired position.
