Description

Technical Field

[0001] This utility model provides a noise reduction frame, belonging to the technical field of shock-absorbing rubber pads and sound barriers, and particularly relates to a combined noise reduction frame based on shock-absorbing rubber pads and sound barriers. Background Technology

[0002] A shock-absorbing frame is a frame structure designed to reduce the impact of vibration and shock on internal components or structures. It is usually made of materials with high elasticity and energy absorption properties, such as rubber, foam, or special plastics. These materials can absorb and disperse energy when subjected to external forces, reducing the vibration transmitted to the interior, thereby protecting the internal equipment from damage and improving the stability and service life of the overall structure.

[0003] While existing shock-absorbing frames can effectively reduce impact, their reliance on mechanical structures such as springs can generate noise and cause acoustic pollution during long-term use. Furthermore, the damping efficiency of metal components like springs decreases after corrosion, thus affecting the performance and lifespan of the shock-absorbing frame. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this application provides a noise reduction frame based on a combination of shock-absorbing rubber pads and sound insulation barriers, which solves the problems of poor noise reduction effect and short service life of existing shock-absorbing frames.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a combined noise reduction frame based on shock-absorbing rubber pads and sound insulation barriers, including a sound insulation board, a plurality of evenly distributed buffer bottom plates are provided below the sound insulation board, and a C-shaped clamping plate corresponding to the buffer bottom plate is sleeved on the outer side of the sound insulation board at the far end, and an evenly distributed L-shaped fixed side plate is fixedly connected above the clamping plate. Shock-absorbing rubber pads are embedded on the side of the buffer bottom plate near the sound insulation board, on the upper and lower inner walls of the clamping plate, and inside the side plate of the fixed side plate.

[0006] Preferably, the buffer base plate has an arc surface on one side and a corresponding slot on the other side, with corresponding mounting holes on the slot and the arc surface.

[0007] Preferably, the clamping plate has fixing plates at both ends corresponding to itself, and the fixing plates have locking holes that correspond to the mounting holes and penetrate through itself.

[0008] Preferably, the two ends of the fixing plate are fitted with the clamping plate through protrusions corresponding to the clamping plate, and the shock-absorbing rubber pads inside the clamping plate are in close contact with the sound insulation plate.

[0009] Preferably, the fixed side plate is provided with an adjustment block corresponding to the corresponding shock-absorbing rubber pad. A limiting plate is provided above the adjustment block, and a groove corresponding to the limiting plate is provided on the other side. A spring is provided inside the groove, and the fixed side plate is also provided with a spring corresponding to the limiting plate.

[0010] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0011] This invention enhances the structural stability of the outer frame and reduces vibration transmission by installing a C-shaped clamping plate and an L-shaped fixed side plate on the outer side of the sound insulation panel away from its outer end. The clamping plate, fixed side plate, and buffer base plate are all embedded with shock-absorbing rubber pads. Utilizing the high elasticity and viscosity of rubber, these pads effectively absorb and isolate vibrations, reducing noise transmission. The viscoelastic properties of rubber make it excellent in vibration damping, sound insulation, and cushioning, while avoiding the performance degradation caused by corrosion of metal components.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] like Figure 1 and Figure 2 As shown, a noise reduction frame based on a combination of shock-absorbing rubber pads and a sound barrier includes a sound insulation panel 1. The sound insulation panel 1 is characterized by the following features: several evenly distributed buffer base plates 2 are provided below it; a U-shaped clamping plate 3 corresponding to the buffer base plate 2 is fitted onto the outer side of one of the sound insulation panels 1, which is far apart from each other; evenly distributed L-shaped fixing side plates 4 are fixedly connected above the clamping plate 3; shock-absorbing rubber pads 5 are embedded on the side of the buffer base plate 2 near the sound insulation panel 1, on the upper and lower inner walls of the clamping plate 3, and inside the side plates of the fixing side plates 4; one side of the buffer base plate 2 has an arc surface 6, and the other side has a slot corresponding to the arc surface 6; the slot and the arc surface 6 have corresponding mounting holes 7 that penetrate through them.

[0023] In this embodiment, the present invention features a U-shaped clamping plate 3, corresponding to the buffer base plate 2, fitted outside one end of the sound insulation plate 1, which is far apart from the other end. Evenly distributed L-shaped fixed side plates 4 are fixedly connected above the clamping plate 3. This design enhances the structural stability of the outer frame and reduces vibration transmission. Shock-absorbing rubber pads 5 are embedded on the side of the buffer base plate 2 closest to the sound insulation plate 1, on the upper and lower inner walls of the clamping plate 3, and inside the side plates of the fixed side plates 4. These shock-absorbing rubber pads 5 utilize the high elasticity and high viscosity of rubber material to effectively absorb and isolate vibrations, reducing the transmission of vibrations to external structures. The coiled long-chain molecular structure of rubber and the relatively weak secondary forces between molecules give the rubber material unique viscoelastic properties, thus providing excellent shock absorption, sound insulation, and buffering performance. Because the rubber shock-absorbing pads possess both high elasticity and high viscosity, they can effectively reduce the generation and propagation of noise, while also avoiding the problem of decreased shock absorption efficiency after metal components corrode.

[0024] like Figure 3 and Figure 4 As shown, the clamping plate 3 has a fixing plate 8 at both ends corresponding to itself. The fixing plate 8 has a locking hole 9 corresponding to the mounting hole 7 and passing through itself. The two ends of the fixing plate 8 are fitted with the clamping plate 3 through the protrusion 10 corresponding to the clamping plate 3. The shock-absorbing rubber pad 5 inside the clamping plate 3 is in close contact with the sound insulation plate 1. The fixing side plate 4 has an adjusting block 11 corresponding to the corresponding shock-absorbing rubber pad 5. The adjusting block 11 has a limiting plate above it and a groove corresponding to the limiting plate on the other side. A spring 12 is provided inside the groove. The fixing side plate 4 also has a spring 12 corresponding to the limiting plate.

[0025] In this embodiment, the two ends of the clamping plate 3 are stably fixed through the cooperation of the fixing plate 8 and the mounting holes 7, enhancing the stability of the overall structure. The locking holes 9 on the fixing plate 8 allow for a tight connection with the clamping plate 3 using bolts or other fasteners, ensuring the robustness of the outer frame. The shock-absorbing rubber pads 5 inside the clamping plate 3 are in close contact with the sound insulation board 1, effectively absorbing the vibration transmitted by the sound insulation board 1 and reducing noise. The fixed side plate 4 is equipped with adjusting blocks 11. Through the design of the limiting plate and the groove, the adjusting blocks 11 can move relative to each other, which can not only adapt to different shapes of equipment bodies, but also increase the shock absorption effect through the bidirectional buffering effect between the adjusting blocks 11. This design not only improves the shock absorption performance of the outer frame, but also enhances its adaptability and durability, so that the outer frame can still maintain good shock absorption and sound insulation effects during long-term use.

[0026] In use, firstly, place several evenly distributed buffer base plates 2 below the sound insulation board 1, ensuring the correct positional relationship between the buffer base plates 2 and the sound insulation board 1; next, fit the C-shaped clamping plates 3 onto the outer side of the sound insulation board 1 at the ends furthest from each other, corresponding to the buffer base plates 2, and then use bolts or other fasteners to tightly connect the fixing plate 8 and the clamping plate 3 through the locking holes 9 and mounting holes 7 on the fixing plate 8, ensuring the sturdiness of the outer frame; subsequently, fix the L-shaped fixing side plates 4 on top of the clamping plate 3, evenly distributed, to enhance the structural stability of the outer frame; then, on the side of the buffer base plate 2 near the sound insulation board 1, on the upper and lower inner walls of the clamping plate 3, and on the side of the fixing side plate 4... The plate is embedded with shock-absorbing rubber pads 5, which absorb and isolate vibrations by utilizing the high elasticity and high viscosity of the rubber material, reducing the transmission of vibrations to the external structure. Then, the buffer base plate 2 is fixed by the cooperation of the arc surface 6 on one side and the slot on the other side, as well as the corresponding mounting holes 7 on the slot and the arc surface 6. Finally, the adjusting blocks 11 in the fixed side plate 4 are adjusted. Through the design of the limiting plate and the groove, the adjusting blocks 11 can move relative to each other to adapt to different shapes of equipment bodies. At the same time, the spring 12 inside the groove provides a two-way buffering effect, increasing the shock absorption effect. This completes the installation and adjustment of the entire device, ensuring that the outer frame maintains good shock absorption and sound insulation effects during long-term use.

[0027] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
