Description

Technical Field

[0001] This utility model relates to the field of sound insulation and noise reduction technology for air conditioning rooms, and more specifically, it relates to a sound insulation and noise reduction device for air conditioning rooms. Background Technology

[0002] With the continuous development of modern building facilities and the widespread application of information technology, air conditioning machine rooms, as important equipment rooms within buildings, typically house a large number of various mechanical devices. These devices generate significant noise pollution during operation. Current technology typically involves multiple cabinets within the machine room to install equipment. These cabinets are usually categorized and arranged according to equipment type and functional requirements, including different types of equipment cabinets such as air conditioning main unit cabinets, cooling water pump cabinets, ventilation fan cabinets, and electrical control cabinets. To effectively control the noise level within the machine room, sound insulation panels are usually installed inside the cabinets to reduce noise transmission and achieve noise reduction. These sound insulation panels generally employ a multi-layer composite structure, consisting of sound-absorbing materials, sound-insulating materials, and a protective surface layer. They can effectively absorb and block sound waves generated during equipment operation, reducing noise propagation. However, existing sound insulation panel installation systems have significant design shortcomings, mainly reflected in the sound insulation panels themselves. The installation and disassembly of soundproofing panels are typically cumbersome, requiring specialized tools such as wrenches, screwdrivers, and drills to tighten or loosen bolts, and pry bars and pliers to install and remove clips. The use of these tools increases the complexity of the operation. In practice, the relatively small space inside the cabinet forces operators to work within a limited area, further increasing the difficulty and leading to time-consuming and labor-intensive operations. This severely impacts maintenance efficiency, and the professional tools may not function properly or there may be insufficient space, potentially preventing timely completion of maintenance work. Furthermore, forced operation could damage the soundproofing panels or surrounding equipment. Therefore, existing soundproofing panel installation systems cannot achieve convenient installation and removal of the panels. This design flaw not only increases equipment maintenance costs and time but may also affect the normal operation of equipment in the computer room and the execution of maintenance plans.

[0003] Secondly, while some equipment has achieved convenient installation of sound insulation panels to address the complexities of traditional installation methods, simplifying the process, reducing reliance on specialized tools, and improving efficiency, these simplified methods often neglect structural stability and reliability. Specifically, the fixing mechanism's design is overly simplistic, lacking sufficient redundancy and safety margins. These design flaws result in low stability of the entire fixing system, making it susceptible to various external forces during actual use. In the actual operating environment of a computer room, the sound insulation panels are subjected to multiple external forces, including... Vibration transmission during operation, airflow impact from air conditioning system operation, accidental collisions when personnel enter and exit the computer room, and operational impacts during equipment maintenance—when these external forces act on the fixed structure, they can easily cause the fixed structure to loosen or even fall off. Loosening of the fixed structure can lead to gaps between the sound insulation panel and the cabinet, which not only affects the sound insulation effect but may also generate additional noise and vibration. If the fixed structure falls off, the sound insulation panel will completely fail, losing its sound insulation function and potentially posing safety hazards to equipment and personnel. In addition, loose or fallen sound insulation panels may also affect air circulation in the computer room, affecting the heat dissipation of the equipment, and thus affecting the normal operation and service life of the equipment.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a sound insulation and noise reduction device for air conditioning rooms, which has the following beneficial effects:

[0017] 1. A quick-release mechanism, composed of components such as a quick-clamp sleeve, quick-clamp rod, rotating sleeve, release groove, release plate, quick-clamp plate, rotating shaft, movable groove, quick-clamp block, guide groove, guide rail, and tension spring, enables convenient installation and removal of sound insulation panels. When the sound insulation panel needs to be removed, rotating the rotating sleeve in the forward direction causes the variable-diameter release groove to rotate, causing the release plate to slide the quick-clamp block outward. The quick-clamp block no longer abuts against the quick-clamp plate. At this point, pulling the quick-clamp sleeve outward causes it to slide out along the guide groove, and the internal ramp structure no longer limits the quick-clamp plate. The tension spring resets, pulling the quick-clamp plate along the rotating shaft and retracting it into the movable groove, completing the removal of the quick-clamp sleeve. Remove the quick-release levers, then remove the other quick-release sleeves and levers, then remove the placement plate and longitudinal frame, and finally take out the sound insulation panel. The entire disassembly and assembly process is simple and intuitive, requiring no professional tools such as wrenches, screwdrivers, electric drills, pry bars, or pliers. This avoids the complexity of multi-step operations requiring tools in traditional installation methods, effectively solving the problem of difficult operation caused by the limited space inside the cabinet. It also eliminates situations where maintenance work is affected by the inability to use tools properly or insufficient operating space, significantly improving maintenance efficiency, reducing equipment maintenance costs and time, and ensuring the smooth execution of maintenance plans and the normal operation of equipment in the computer room.

[0018] 2. A multi-locking and stabilizing mechanism, including a limiting sleeve, round rod, round plate, rotating plate, arc-shaped groove, round hole, rotating frame, limiting rod, limiting plate, limiting groove, spring, and connecting spring, ensures the structural stability and reliability of the sound insulation panel after installation. After installation, the rotating plate drives the arc-shaped groove and round hole to a position not corresponding to the round rod and round plate. The round rod, in conjunction with the round plate, supports and limits the limiting sleeve to one side of the rotating plate, preventing easy sliding. The inner wall of the limiting sleeve limits the outer wall of the limiting plate, preventing the limiting plate and limiting rod from sliding outwards. The limiting rod and limiting groove work together to limit the rotating frame, preventing accidental rotation of the rotating frame and rotating sleeve, thus creating a multi-layered stabilizing and locking effect. This multi-locking design effectively solves the problem of… Traditional convenient installation methods suffer from simple fixing structures and insufficient stability. This device effectively resists the effects of various external forces, such as vibration transmission generated during equipment operation, airflow impact from air conditioning systems, accidental collisions when personnel enter or exit the computer room, and operational impacts during equipment maintenance. It avoids the problem of the fixing structure loosening or even falling off due to these external forces, prevents gaps between the sound insulation panel and the cabinet from affecting the sound insulation effect and generating additional noise vibrations, eliminates the safety hazards caused by the complete failure of the sound insulation panel due to the fixing structure falling off, ensures the stable fixing of the sound insulation panel and its continuous and effective sound insulation and noise reduction function, guarantees air circulation and equipment heat dissipation in the computer room, and improves the normal operation and service life of the equipment.

A limiting sleeve 9 is slidably mounted on the outside of the quick-lock sleeve 4. A round rod 10 is connected to one side of the limiting sleeve 9. A round plate 11 is fixed on the round rod 10, and the round plate 11 has two locations. A rotating sleeve 12 is rotatably mounted on the outside of the quick-lock sleeve 4. The side-diameter type has a release groove 13. A rotating frame 14 is fixedly installed on one side of the rotating sleeve 12. A limiting rod 15 is slidably installed in the rotating frame 14. A limiting plate 16 is fixedly connected to one end of the limiting rod 15. A release plate 17 is slidably installed in the release groove 13. A movable groove 18 is opened on the outside of the quick-locking rod 5. A quick-locking plate 19 is installed in the movable groove 18. A rotating shaft 20 is provided on both sides of the quick-locking plate 19. The quick-locking plate 19 is rotatably installed in the movable groove 18 through the rotating shaft 20. A plurality of limiting grooves 21 are opened on the outside of the quick-locking sleeve 4. One end of the limiting rod 15 is inserted into the limiting groove 21. A quick-locking block 22 is connected to one side of the release plate 17. One side of the quick-locking block 22 abuts against one end of the quick-locking plate 19.

[0029] A handle 23 is detachably provided on one side of cabinet door 2, and a bracket 24 is fixedly provided at the bottom of cabinet 1.

[0030] Multiple exhaust holes 25 are provided on the cabinet door 2 and one of the sound insulation panels 3, and multiple air inlets 26 are provided on the bottom of the cabinet 1 and one of the sound insulation panels 3.

[0031] A vertical rack 27 is placed inside the cabinet 1. Multiple placement plates 28 are detachably installed inside the vertical rack 27. Multiple ventilation slots 29 are opened on the placement plates 28.

[0032] In this embodiment, when it is necessary to remove the sound insulation panel 3 from the inside of the cabinet 1 or the cabinet door 2, firstly, remove the equipment installed on the placement plate 28, then remove the vertical frame 27 along with the placement plate 28, and then rotate the rotating plate 6 in the forward direction, so that the rotating plate 6 drives the circular hole 8 and the arc groove 7 to rotate in the forward direction. When the circular hole 8 rotates to a position concentric with the circular plate 11, push the limiting sleeve 9. The limiting sleeve 9 will drive the circular rod 10 and the circular plate 11 on one side to gradually slide into the circular hole 8, and the limiting sleeve 9 will cooperate with the rotating plate 6 to compress the spring 30. When the spring 30 is compressed to its limit, the side closest to the limiting sleeve 9 The circular plate 11 slides through the circular hole 8 and moves to the other side of the rotating plate 6. Then, the circular plate 11 is rotated in the opposite direction, causing the circular hole 8 and the arc groove 7 to rotate in the opposite direction, so that the circular rod 10 enters the arc groove 7. At this time, the circular rod 10 and the circular plate 11 near the limiting sleeve 9 cooperate to limit the limiting sleeve 9 to one side of the rotating plate 6. Then, the inner wall of the limiting sleeve 9 no longer limits the outer wall of the limiting plate 16. Then, the rotating sleeve 12 is rotated in the forward direction. The rotating sleeve 12 will drive the rotating frame 14 on one side to rotate in the forward direction. Then, the rotating frame 14 will drive the limiting rod 15, the limiting plate 16, and the connecting spring 31. The device rotates in the forward direction, and then the inner wall of the limiting groove 21 presses against one end of the limiting rod 15. Due to the rounded corner design of the inner wall edge of the limiting groove 21 and one end of the limiting rod 15, one end of the limiting rod 15 slides out of the limiting groove 21, and the other end of the limiting rod 15 is stretched outward by the connecting spring 31 driven by the limiting plate 16. At the same time, the rotating sleeve 12 will drive the inner variable diameter opening of the release groove 13 to rotate in the forward direction, and then the release plate 17 will move in the release groove 13, so that the release plate 17 drives one side of the quick-lock block 22 to slide outward, so that the quick-lock block 22 no longer abuts against one end of the quick-lock plate 19. Then, pull the quick-release sleeve 4 outwards, causing the quick-release sleeve 4 to drive the inner guide rail 33 to gradually slide out along the guide groove 32. The ramp structure at the top of the quick-release sleeve 4 will gradually stop limiting the outer wall of the quick-release plate 19. Then, the tension spring 34 will reset and pull the quick-release plate 19, causing the quick-release plate 19 to rotate along the rotating shaft 20. Then, one end of the quick-release plate 19 will gradually be retracted into the movable groove 18. Then, the quick-release sleeve 4 will be completely removed. Then, the quick-release rod 5 will be removed from the inside of the cabinet 1. Then, follow the above steps to remove the other quick-release sleeves 4 and quick-release rods 5. Then, the sound insulation panels 3 can be removed one by one.

[0033] Please see Figures 3-5 As a further implementation of the overall equipment: a spring 30 is connected to one side of the limiting sleeve 9, the other end of the spring 30 abuts against one side of the rotating plate 6, and the spring 30 is movably sleeved on the outside of the round rod 10.

[0034] A connecting spring 31 is movably sleeved on the outside of the limiting rod 15, and the two ends of the connecting spring 31 are connected to the limiting plate 16 and the rotating frame 14 respectively.

[0035] The quick-release lever 5 has a guide groove 32 on its outer side, and the quick-release sleeve 4 has a guide rail 33 fixed on its inner side. The guide groove 32 and the guide rail 33 are compatible.

[0036] A tension spring 34 is connected to one side of the quick-release plate 19, and the other end of the tension spring 34 is connected to the inner wall of the movable groove 18.

[0037] More specifically, when the sound insulation panel 3 needs to be installed, firstly, the sound insulation panels 3 are installed one by one on the inner wall of the cabinet 1, so that the sound insulation panels 3 are in close contact with the inner wall of the cabinet 1. Then, the quick-release lever 5 passes through the sound insulation panel 3 and the side wall of the cabinet 1 from the inside. Then, the quick-release sleeve 4 is fitted onto the outside of the quick-release lever 5 from the outside, so that the inner guide rail 33 of the quick-release sleeve 4 slides into the guide groove 32. At the same time, the sloping structure at the top of the quick-release sleeve 4 gradually limits the outer wall of the quick-release plate 19, so that one end of the quick-release plate 19 gradually retracts inward. Then, the quick-release plate 19 rotates in the opposite direction along the rotating shaft 20, so that the quick-release plate 19 drives the tension spring 34 on one side to stretch outward, and the other end of the quick-release plate 19 gradually rotates out of the movable groove 18. Then, the release sleeve is rotated in the opposite direction, and the release sleeve will drive the rotating frame 14 on one side to rotate. The rotating frame 14 rotates in the opposite direction, causing the limiting rod 15, limiting plate 16, and connecting spring 31 to rotate in the opposite direction. Simultaneously, the rotating sleeve 12 rotates the inner release groove 13 in the opposite direction. The release plate 17 then causes the quick-lock block 22 to slide in the opposite direction, resetting it inwards. The quick-lock block 22 then re-abuts against one end of the quick-lock plate 19, preventing it from moving. At this point, the quick-lock block 22 is fully reset, and the rotating sleeve 12 stops rotating. The rotating frame 14 then rotates the limiting rod 15 and other components to their original positions corresponding to the original limiting groove 21. The connecting spring 31 then resets and pulls the limiting plate 16, causing the limiting plate 16 to slide the limiting rod 15 inwards. Finally, one end of the limiting rod 15 is reinserted into its original position. In the limiting groove 21, the rotating plate 6 is rotated forward again, causing the rotating plate 6 to drive the circular hole 8 and the arc-shaped groove 7 to rotate forward again. When the circular hole 8 rotates to the position concentric with the circular plate 11, the spring 30 pushes the limiting sleeve 9 to slide and reset. Then, the limiting sleeve 9 drives the two circular plates 11 to slide and reset through the circular rod 10. When the spring 30 is fully reset, the circular plate 11 at the top of the circular rod 10 moves back to the original side of the rotating plate 6. Then, the rotating plate 6 is rotated in the opposite direction again, causing the rotating plate 6 to drive the arc-shaped groove 7 and the circular hole 8 to rotate to a position that does not correspond to the circular rod 10 and the circular plate 11. Then, the circular rod 10, together with the top circular plate 11, supports and limits the limiting sleeve 9 to one side of the rotating plate 6, so that the limiting sleeve 9 cannot slide easily. Then, the inner wall of the limiting sleeve 9 limits the outer wall of the limiting plate 16. This prevents the limiting plate 16 and limiting rod 15 from sliding outwards. The limiting rod 15 and limiting groove 21 then cooperate to limit the rotation frame 14, preventing accidental rotation of the rotation frame 14 and rotation sleeve 12, thus ensuring installation stability. Following the same steps, the other quick-lock sleeves 4 and quick-lock rods 5 are then engaged one by one. The longitudinal frame 27, along with the placement plate 28, is then installed inside the cabinet 1. The equipment is then installed on the placement plate 28. Following the same steps, a corresponding soundproofing plate 3 is installed on one side of the cabinet door 2. When in use, the air inlet 26 at the bottom of the cabinet 1 and the exhaust vent 25 on one side of the cabinet door 2 form a complete airflow channel, ensuring ventilation. Various integrated devices can be installed on the placement plate 28 inside the longitudinal frame 27.The multiple ventilation slots 29 on the panel ensure airflow and prevent interference with the heat dissipation of internal equipment, while the sound insulation panel 3 effectively absorbs noise, achieving noise reduction.

[0038] In summary, when using or operating the overall equipment: When it is necessary to remove the sound insulation panel 3 from the inside of the cabinet 1 or one side of the cabinet door 2, first remove the equipment installed on the placement plate 28, then remove the longitudinal frame 27 along with the placement plate 28. Next, rotate the rotating plate 6 forward, causing the rotating plate 6 to drive the circular hole 8 and the arc-shaped groove 7 to rotate forward. When the circular hole 8 rotates to a position concentric with the circular plate 11, push the limiting sleeve 9. The limiting sleeve 9 will cause one side of the circular rod 10 and the circular plate 11 to gradually slide into the circular hole 8. The limiting sleeve 9 will cooperate with the rotating plate 6 to compress the spring 30. When the spring 30 is compressed to its limit, it will... A circular plate 11 near the limiting sleeve 9 slides through the circular hole 8 and moves to the other side of the rotating plate 6. Then, the circular plate 11 is rotated in the opposite direction, causing the circular hole 8 and the arc groove 7 to rotate in the opposite direction, so that the circular rod 10 enters the arc groove 7. At this time, the circular rod 10 and the circular plate 11 near the limiting sleeve 9 cooperate to limit the limiting sleeve 9 to one side of the rotating plate 6. Then, the inner wall of the limiting sleeve 9 no longer limits the outer wall of the limiting plate 16. Then, the rotating sleeve 12 is rotated in the forward direction. The rotating sleeve 12 will drive the rotating frame 14 on one side to rotate in the forward direction. Then, the rotating frame 14 will drive the limiting rod 15 and the limiting plate 16 and the connecting rod 16 to rotate in the forward direction. The connecting spring 31 rotates in the forward direction, and then the inner wall of the limiting groove 21 presses against one end of the limiting rod 15. Due to the rounded corner design of the inner wall edge of the limiting groove 21 and one end of the limiting rod 15, one end of the limiting rod 15 slides out of the limiting groove 21, and the other end of the limiting rod 15 drives the connecting spring 31 to stretch outward through the limiting plate 16. At the same time, the rotating sleeve 12 drives the inner variable-diameter opening of the release groove 13 to rotate in the forward direction, and then the release plate 17 moves in the release groove 13, so that the release plate 17 drives one side of the quick-locking block 22 to slide outward, so that the quick-locking block 22 no longer abuts against the quick-locking plate 19. Remove one end of the quick-release sleeve 4 and pull it outwards, causing the quick-release sleeve 4 to drive the inner guide rail 33 to gradually slide out along the guide groove 32. The ramp structure at the top of the quick-release sleeve 4 will gradually stop limiting the outer wall of the quick-release plate 19. Then the tension spring 34 will reset and pull the quick-release plate 19, causing the quick-release plate 19 to rotate along the rotating shaft 20. Then one end of the quick-release plate 19 will gradually be retracted into the movable groove 18. Then the quick-release sleeve 4 will be completely removed. Then the quick-release rod 5 will be removed from the inside of the cabinet 1. Then, the other quick-release sleeves 4 and quick-release rods 5 will be removed according to the above steps. Then the sound insulation panels 3 can be removed one by one.

[0039] When the sound insulation panel 3 needs to be installed, first install the sound insulation panels 3 one by one on the inner wall of the cabinet 1, making the sound insulation panels 3 fit against the inner wall of the cabinet 1. Then, pass the quick-release lever 5 through the sound insulation panel 3 and the side wall of the cabinet 1 from the inside. Then, fit the quick-release sleeve 4 from the outside to the outside of the quick-release lever 5, and let the inner guide rail 33 of the quick-release sleeve 4 slide into the guide groove 32. At the same time, the sloping structure at the top of the quick-release sleeve 4 gradually limits the outer wall of the quick-release plate 19, so that one end of the quick-release plate 19 gradually retracts inward. Then, the quick-release plate 19 rotates in the opposite direction along the rotating shaft 20, so that the quick-release plate 19 drives the tension spring 34 on one side to stretch outward, and the other end of the quick-release plate 19 gradually rotates out of the movable groove 18. Then, rotate the release sleeve in the opposite direction, and the release sleeve will drive the rotating frame 14 on one side to rotate in the opposite direction. Then, the rotating frame 14 will drive the limiting rod 15, the limiting plate 16, and the connecting spring 31 to rotate in the opposite direction. At the same time, the rotating sleeve 12 will drive the inner release groove 13 to rotate in the opposite direction. Then, the release plate 17 will drive the quick-lock block 22 to slide in the opposite direction, so that the quick-lock block 22 slides inward to reset. Then, the quick-lock block 22 will abut against one end of the quick-lock plate 19 again, so that the quick-lock plate 19 will not move. At this time, the quick-lock block 22 is completely reset, and the rotating sleeve 12 stops rotating. At this time, the rotating frame 14 drives the limiting rod 15 and other components to rotate and reset to the position corresponding to the original limiting groove 21. Then, the connecting spring 31 resets and pulls the limiting plate 16, so that the limiting plate 16 drives the limiting rod 15 to slide inward. Then, one end of the limiting rod 15 is reinserted into the original limiting groove. In step 21, the rotating plate 6 is rotated forward again, causing the rotating plate 6 to drive the circular hole 8 and the arc groove 7 to rotate forward again. When the circular hole 8 rotates to the position concentric with the circular plate 11, the spring 30 pushes the limiting sleeve 9 to slide and reset. Then, the limiting sleeve 9 drives the two circular plates 11 to slide and reset through the circular rod 10. When the spring 30 is fully reset, the circular plate 11 at the top of the circular rod 10 moves back to the original side of the rotating plate 6. Then, the rotating plate 6 is rotated in the opposite direction again, causing the rotating plate 6 to drive the arc groove 7 and the circular hole 8 to rotate to a position that is not corresponding to the circular rod 10 and the circular plate 11. Then, the circular rod 10, together with the top circular plate 11, supports and limits the limiting sleeve 9 to one side of the rotating plate 6, so that the limiting sleeve 9 cannot slide easily. Then, the inner wall of the limiting sleeve 9 limits the outer wall of the limiting plate 16, so that... The limiting plate 16 and limiting rod 15 cannot slide outwards. Then, the limiting rod 15 and the limiting groove 21 cooperate to limit the rotation frame 14, preventing the rotation frame 14 and the rotation sleeve 12 from rotating accidentally, thus ensuring installation stability. Then, following the above steps, the other quick-clamp sleeves 4 and quick-clamp rods 5 are engaged one by one. Then, the longitudinal frame 27, along with the placement plate 28, is installed into the cabinet 1. Then, the equipment is installed on the placement plate 28. Then, following the above steps, a corresponding sound insulation plate 3 is installed on one side of the cabinet door 2. When the equipment is in use, the air inlet 26 at the bottom of the cabinet 1 and the exhaust vent 25 on one side of the cabinet door 2 form a complete air circulation channel to ensure ventilation. Various integrated devices can be installed on the placement plate 28 inside the longitudinal frame 27.The multiple ventilation slots 29 on the panel ensure airflow and prevent interference with the heat dissipation of internal equipment, while the sound insulation panel 3 effectively absorbs noise, achieving noise reduction.
