Description

Technical Field

[0001] This utility model relates to the field of cabinet technology, and in particular to a cabinet sound insulation structure. Background Technology

[0002] In server rack applications, the internal equipment generates noise during operation, such as the fan rotation of servers and switches, and the noise from circuit operation. If this noise is not controlled, it will interfere with the surrounding environment, affect the work efficiency and quality of life of staff, and may also lead to the risk of information leakage due to noise propagation.

[0003] Traditional cabinet soundproofing structures have many shortcomings. On the one hand, the installation and disassembly of soundproofing panels are complicated, often using methods such as bolt tightening and glue bonding. Bolt tightening requires individual operation, which is time-consuming. Although glue bonding can fix the panels, it is not only difficult to clean the residual glue when disassembling and replacing the panels later, but it can also easily damage the cabinet or the soundproofing panels, increasing maintenance costs and difficulties, and hindering the timely maintenance and replacement of the soundproofing panels. Therefore, a cabinet soundproofing structure is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing cabinet sound insulation structure, which is often difficult to install and disassemble due to the complicated installation method, such as the use of a large number of bolts and glue for fixing, and the time-consuming and labor-intensive maintenance in the later stage. Therefore, a cabinet sound insulation structure is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cabinet sound insulation structure, including a cabinet body, an installation groove is provided on the surface of the cabinet body, a sound insulation plate is slidably connected to the inner surface of the installation groove, four limiting plates are fixedly connected to the surface of the sound insulation plate, four positioning frames are fixedly connected to the surface of the cabinet body, the limiting plates are slidably connected to the surfaces of the positioning frames, a fixing rod is fixedly connected to the inner surface of the positioning frame, and a clamping plate is rotatably connected to the arc surface of the fixing rod.

[0006] The effect achieved by the above components is as follows: the sound insulation panel can be quickly installed and removed in the cabinet mounting slot by sliding cooperation between the limiting plate and the positioning frame, and then combined with the card plate connected by the fixed rod. This facilitates the maintenance and replacement of the sound insulation panel in the later stage, improves the convenience of operation, and avoids the difficulties in installing and removing the sound insulation panel and the time-consuming and laborious maintenance caused by the complex installation method of traditional cabinet sound insulation structure, such as the use of a large number of bolts and glue for fixing.

[0007] Preferably, the arc surface of the fixing rod is fitted with two torsion springs, which are respectively fixedly connected to the clamping plate and the positioning frame.

[0008] The effect achieved by the above components is as follows: the torsion spring is sleeved on the arc surface of the fixing rod, and both ends are fixed to the clamping plate and the positioning frame respectively.

[0009] Preferably, an iron block is fixedly connected to one side of the card plate, and a magnet is fixedly connected to the inner surface of the positioning frame.

[0010] The effect achieved by the above components is that the iron block on the card plate attracts the magnet in the positioning frame.

[0012] The effect achieved by the above components is as follows: the guide plate on the cabinet surface can guide the sliding direction of the sound insulation board during installation, so that the limiting plate on the sound insulation board can slide into the positioning frame accurately and smoothly, reducing the installation difficulty, improving the installation efficiency, and avoiding the situation where the sound insulation board cannot be installed properly or is not fixed firmly due to installation deviation.

[0013] Preferably, an elastic sealing ring is fixedly connected to the surface of the cabinet.

[0015] Preferably, sound-absorbing cotton is fixedly connected to the surface of the sound insulation board, and the surface of the sound-absorbing cotton has a plurality of sound-absorbing holes.

[0016] The effects achieved by the above components are as follows: the sound-absorbing cotton and sound-absorbing holes on the surface of the sound insulation board absorb and block noise by utilizing the material properties of the sound-absorbing cotton, and the sound-absorbing holes can further enhance the absorption and scattering effect of sound, reflecting sound waves multiple times and consuming energy within the sound-absorbing holes, significantly improving the sound insulation performance of the sound insulation structure and better reducing the impact of noise from the equipment inside the cabinet on the outside world.

[0017] Preferably, the elastic sealing ring is in the shape of a loop.

[0018] The effect achieved by the above components is as follows: the U-shaped elastic sealing ring is adapted to the shape of the cabinet frame, and can fully and tightly fit the contact parts between the cabinet body and the cabinet door, sealing the gaps in all directions, ensuring the uniformity and comprehensiveness of sound insulation, dust prevention and moisture prevention effects, and avoiding sealing dead corners due to unreasonable sealing ring shape, which would affect the overall performance.

[0027] Reference Figure 1-5As shown, this utility model provides a technical solution: a cabinet sound insulation structure, including a cabinet body 1. A mounting groove 2 is formed on the surface of the cabinet body 1. A sound insulation plate 13 is slidably connected to the inner surface of the mounting groove 2. Four limiting plates 3 are fixedly connected to the surface of the sound insulation plate 13. Four positioning frames 4 are fixedly connected to the surface of the cabinet body 1. The limiting plates 3 and the positioning frames 4 are slidably connected. A fixing rod 5 is fixedly connected to the inner surface of the positioning frame 4. A clamping plate 6 is rotatably connected to the arc surface of the fixing rod 5. Two torsion springs 7 are sleeved on the arc surface of the fixing rod 5. The torsion springs 7 are fixedly connected to the clamping plate 6 and the positioning frames 4 respectively. The torsion springs 7 are sleeved on the arc surface of the fixing rod 5, and their two ends are respectively connected to the clamping plate 6 and the positioning frames. 4. For fixation, the torsion spring 7 provides elastic resistance, enhancing the reliability of the clamping plate 6 in fixing the sound insulation panel 13 and preventing the clamping plate 6 from loosening and causing the sound insulation panel 13 to shift. An iron block 8 is fixedly connected to one side of the clamping plate 6, and a magnet 9 is fixedly connected to the inner surface of the positioning frame 4. The iron block 8 on the clamping plate 6 and the magnet 9 in the positioning frame 4 attract each other. After the clamping plate 6 is reset, the magnetic force is used to further stabilize the position of the clamping plate 6, so that the staff can disassemble the sound insulation panel 13. Two guide plates 10 are fixedly connected to the surface of the cabinet 1. The guide plates 10 on the surface of the cabinet 1 can guide the sliding direction of the sound insulation panel 13 during installation, so that the limiting plate 3 on the sound insulation panel 13 can be accurately positioned. The soundproof panel 13 slides smoothly into the positioning bracket 4, reducing installation difficulty and improving installation efficiency. This avoids situations where the soundproof panel 13 cannot be properly installed or is not securely fixed due to installation deviations. An elastic sealing ring 11 is fixedly connected to the surface of the cabinet 1. After the soundproof panel 13 is installed, the elastic sealing ring 11 on the surface of the cabinet 1 fills the gap between the cabinet door and the cabinet 1, enhancing the overall sealing of the cabinet and effectively blocking noise transmission through the gaps, thus improving the sound insulation effect. It also provides some dust and moisture protection, protecting the internal equipment of the cabinet. Sound-absorbing cotton 12 is fixedly connected to the surface of the soundproof panel 13. The surface of the sound-absorbing cotton 12 has several sound-absorbing holes. The sound-absorbing cotton 12 and the sound-absorbing holes utilize the material properties of the sound-absorbing cotton 12 to absorb and block noise. The sound-absorbing holes further enhance the absorption and scattering effect of sound, reflecting sound waves multiple times and consuming energy within the sound-absorbing holes, significantly improving the sound insulation performance of the sound insulation structure and better reducing the impact of noise from the equipment inside the cabinet on the outside world. The elastic sealing ring 11 is U-shaped, which matches the shape of the cabinet frame and can fully and tightly fit the contact area between the cabinet body 1 and the cabinet door, sealing the gaps in all directions. This ensures the uniformity and comprehensiveness of the sound insulation, dustproof, and moisture-proof effects, avoiding sealing dead corners caused by unreasonable sealing ring shape, which would affect the overall performance.

[0028] Working principle: When installing the sound insulation panel 13, the guide plate 10 on the surface of the cabinet 1 guides the sound insulation panel 13 to the mounting groove 2 of the cabinet 1. This allows the limiting plate 3 on the sound insulation panel 13 to slide precisely into the positioning frame 4 along the guide direction. During the sliding process, the limiting plate 3 pushes the clamping plate 6 inside the positioning frame 4 to rotate. The clamping plate 6 rotates around the arc surface of the fixing rod 5. After the limiting plate 3 has completely slid into the appropriate position of the positioning frame 4, the iron block 8 on one side of the clamping plate 6 no longer contacts the magnet 9 inside the positioning frame 4. The torsion spring 7 releases its elastic force, providing elastic resistance and enhancing the reliability of the clamping plate 6 in fixing the sound insulation panel 13. This prevents the clamping plate 6 from loosening and causing the sound insulation panel 13 to shift. When disassembling, rotate in the opposite direction. The card plate 6 overcomes the elastic force of the torsion spring 7, causing the iron block 8 on one side of the card plate 6 to be magnetically attracted to the magnet 9 inside the positioning frame 4. The sound insulation board 13 can then be slidably pulled out along the mounting groove 2, which facilitates maintenance and replacement and simplifies the operation process. The sound-absorbing cotton 12 and sound-absorbing holes on the surface of the sound insulation board 13 absorb and block the noise generated by the equipment inside the cabinet by means of the material properties of the sound-absorbing cotton 12. The sound-absorbing holes consume energy through multiple reflections and scattering of sound waves, which enhances the noise reduction effect. At the same time, the U-shaped elastic sealing ring 11 on the surface of the cabinet 1 tightly fills the contact gap between the cabinet 1 and the cabinet door after the sound insulation board 13 is installed in place, forming an all-round seal to prevent noise leakage. It can also prevent dust and moisture, and protect the stable operation of the equipment inside the cabinet.
