Especially in theaters, due to the strict requirements for acoustic performance, noise control and vibration reduction technologies are particularly important. During the operation of electromechanical equipment such as machine room equipment, air conditioning ventilation systems, and pipes, vibration and noise are often transmitted through rigid structures, seriously affecting the sound quality effect and overall use experience of the auditorium.

Specific embodiments
[0032] See Figures 1 to 4 As shown, a shock isolation hanging bracket for vibration damping and noise reduction of a ventilation duct includes a connecting U-shaped frame 100. A vibration damping connecting arm 200 fixedly connected to a wall is arranged on the connecting U-shaped frame 100. A shock isolation sleeve 300 connected to the connecting U-shaped frame 100 is arranged in the connecting U-shaped frame 100. Two groups of connecting rods 400 are symmetrically arranged on the shock isolation sleeve 300. Each group of the connecting rods 400 includes a plurality of connecting rods 400 uniformly arranged along the axial direction of the shock isolation sleeve 300. A plurality of connecting grooves are vertically formed on both end faces of the opening of the connecting U-shaped frame 100;
[0033] The connecting rod 400 penetrates through the connecting groove, and a first shock isolation component 500 cooperating with the connecting rod 400 is arranged on the connecting U-shaped frame 100. A second shock isolation component 600 cooperating with the ventilation duct and cooperating with the first shock isolation component 500 is arranged in the shock isolation sleeve 300. Noise reduction sleeve assemblies 700 cooperating with the ventilation duct are arranged at both ends of the shock isolation sleeve 300.
[0034] Specifically, the connecting U-frame 100 serves as the load-bearing member of the entire device and fixes the vibration isolation hanger to the building structure. The vibration damping connecting arm 200 is used to connect the U-frame 100 to the wall surface, and absorbs vibrations through its elastic deformation. The vibration isolation sleeve 300, as the core component of the vibration isolation system, achieves vibration isolation and noise reduction through the internal vibration isolation components and noise reduction components. The connecting rod 400 is used to connect the vibration isolation sleeve 300 and the connecting U-frame 100 and transmit loads. The first vibration isolation component 500 provides primary vibration isolation between the connecting U-frame 100 and the vibration isolation sleeve 300 and absorbs part of the vibration energy. The second vibration isolation component 600 provides vibration isolation between the ventilation duct and the vibration isolation sleeve 300 and jointly realizes multi-stage vibration isolation with the first vibration isolation component 500. The noise reduction sleeve component 700 reduces the noise generated by the ventilation duct through sound-absorbing materials and special structural designs.
[0035] Preferably, two structural designs of the first vibration isolation component 500 are provided, which are specifically as follows:
[0036] First, the first vibration isolation component 500 includes a vibration isolation seat 510 that is slidably matched with the connecting groove. A limit seat 520 that cooperates with the connecting U-frame 100 is provided on the vibration isolation seat. A limit screw 530 that cooperates with the connecting U-frame 100 is provided on the limit seat 520. A circumferential sleeve frame 540 is provided on the vibration isolation seat. A vibration isolation ring sleeve 550 that contacts the connecting rod 400 is provided in the circumferential sleeve frame 540. A limit screw 530 that cooperates with the connecting rod 400 is provided on the vibration isolation ring sleeve. A circumferential spring 560 is provided between the vibration isolation ring sleeve 550 and the circumferential sleeve frame 540.
[0037] Second, the first vibration isolation component 500 includes a vibration isolation sleeve frame 570 connected to the connecting U-frame 100. A vibration isolation cylinder 580 is provided on the connecting rod 400. A fastening screw that cooperates with the connecting rod 400 is provided on the vibration isolation cylinder 580. A number of shock-absorbing connecting members 590 are provided between the vibration isolation sleeve frame and the vibration isolation cylinder 580.
[0038] The shock-absorbing connecting member 590 is provided as a shock-absorbing pull rope or a shock-absorbing spring.
[0039] Specifically, through two different structural designs, the first vibration isolation component 500 realizes the elastic connection between the connecting rod 400 and the connecting U-frame 100, thereby effectively reducing the vibration transmission generated by the ventilation duct in the suspended state. Both of these designs utilize elastic elements to absorb vibration energy and ensure the stability and reliability of the structure through limiting devices. Through such a design, this technical solution can significantly reduce the impact of the ventilation duct on the surrounding environment during operation and improve the comfort level inside the building.
[0040] Upon further analysis, in the first structural design, due to the action of the circumferential spring 560, when the connecting rod 400 is vibrated, the circumferential spring 560 can absorb a part of the vibration energy, thereby reducing the transmission of vibration to the connecting U-frame 100 and other structures. Subsequently, through the combined use of the limit seat 520 and the limit screw 530, the movement range of the vibration isolation seat 510 can be restricted, avoiding structural damage caused by excessive displacement. At the same time, through the sliding fit between the vibration isolation seat 510 and the connecting U-frame 100, it is ensured that the connecting rod 400 can obtain a certain degree of freedom during vibration, while maintaining the overall stability of the structure through the limit seat 520 and the limit screw 530. In the second structural design, due to the action of the shock-absorbing connecting member 590, when the connecting rod 400 is vibrated, the shock-absorbing connecting member 590 can absorb a part of the vibration energy, thereby reducing the transmission of vibration to the connecting U-frame 100 and other structures. Through the connection between the vibration isolation sleeve frame 570 and the connecting U-frame 100, and the fixing of the shock-absorbing cylinder 580 to the connecting rod 400 with fastening screws, the entire structure is easy to install and maintain. Finally, through the design of the shock-absorbing connecting member 590, it is ensured that the connecting rod 400 can be effectively buffered during vibration, reducing the impact on the overall structure and improving the reliability of the system.
[0041] Further, the second vibration isolation assembly 600 includes a plurality of vibration isolation support units 610 arranged in the shock-absorbing sleeve 300 along the axial direction of the shock-absorbing sleeve 300. The vibration isolation support unit includes a support ring frame 611 in contact with the shock-absorbing sleeve 300. A stabilizing ring frame 612 sleeved on the ventilation duct is arranged in the support ring frame 611, and a shock-absorbing spring 613 is arranged between the support ring frame 611 and the support ring frame 611.
[0042] Preferably, a first screw cooperating with the stabilizing ring frame 612 is arranged on the shock-absorbing sleeve 300, and a second screw cooperating with the ventilation duct is arranged on the stabilizing ring frame 612.
[0043] Further, the second vibration isolation assembly 600 further includes a vibration isolation cable unit 620 cooperating with the vibration isolation support unit. The shock-absorbing cable unit includes a vibration isolation ring frame 621 in contact with the inner barrel wall of the shock-absorbing sleeve 300. A shock-absorbing ring cylinder 622 is sleeved on the ventilation duct, and a plurality of shock-absorbing cables 623 are uniformly arranged along the circumferential direction of the shock-absorbing ring sleeve.
[0044] Preferably, vibration isolation rubber pads cooperating with the ventilation duct are arranged on both the support ring frame 611 and / or the shock-absorbing ring cylinder 622.
[0045] Preferably, two vibration isolation cable units 620 are arranged and are respectively located at both ends of the shock-absorbing sleeve 300.
[0046] Specifically, in the structural design of the second vibration isolation component 600, the radial vibration of the ventilation duct is absorbed through the vibration isolation spring 613 and the vibration isolation cable unit 620. The vibration isolation spring 613 is located between the support ring frames 611, which can absorb and disperse the vibration energy of the ventilation duct and reduce the transmission of vibration to the wall or other structures. At the same time, by closely contacting the ventilation duct through the stabilizing ring frame 612, the stability of the ventilation duct in the vibration isolation sleeve 300 is ensured, and the displacement caused by vibration is reduced. The vibration isolation cable unit 620 is evenly distributed on the vibration isolation ring frame 621, which helps to evenly disperse the weight and vibration of the ventilation duct and avoid local overload. In addition, the direct contact between the ventilation duct and the vibration isolation sleeve 300 is reduced through the vibration isolation rubber pad, further reducing the vibration transmission and protecting the ventilation duct from wear.
[0047] Furthermore, the noise reduction sleeve assembly 700 includes a noise reduction ring cylinder 710 sleeved on the vibration isolation sleeve 300. A noise reduction ring plate 720 is provided at one end of the noise reduction ring cylinder 710, and a through groove matching the ventilation duct is opened on the noise reduction ring plate 720.
[0048] Preferably, a sound absorption ring wall area 730 made of sound insulation cotton is provided in the noise reduction ring cylinder 710.
[0049] Preferably, receiving ring grooves 740 matching the noise reduction ring cylinder 710 are provided at both ends of the vibration isolation sleeve 300.
[0050] Specifically, through the sound absorption ring wall area 730 in the noise reduction ring cylinder 710, the noise transmitted by the ventilation duct is absorbed by the sound insulation cotton, reducing the propagation of noise. The design of the noise reduction ring cylinder 710 and the noise reduction ring plate 720 can effectively isolate the noise transmission path between the ventilation duct and the external environment and reduce the impact of noise on the external environment. By absorbing and reducing noise, the acoustic environment inside the building is improved, and the comfort of living or working is enhanced. Through the design of the receiving ring grooves 740, the installation and disassembly of the noise reduction sleeve assembly 700 are facilitated, which is convenient for maintenance and cleaning.
[0051] Generally speaking, the second vibration isolation component 600 realizes the elastic connection between the ventilation duct and the vibration isolation sleeve 300 through structures such as the vibration isolation support unit and the support ring frame, effectively absorbs the radial vibration of the ventilation duct, and reduces the vibration transmission. At the same time, the direct contact between the ventilation duct and the vibration isolation sleeve 300 is reduced through the vibration isolation rubber pad, further reducing the effect of vibration transmission. The noise reduction sleeve assembly 700 absorbs noise through materials such as sound insulation cotton, reduces the propagation of noise, and improves the comfort of the environment. The combined action of these two components provides comprehensive vibration and noise reduction protection for the ventilation duct, improving the stability of the system and the quality of the use environment.
[0052] Further, the seismic isolation sleeve 300 includes two symmetrically arranged semi-circular sleeves, and connecting screws for connecting another semi-circular sleeve are arranged at both ends of the opening of the semi-circular sleeve; and a set of the connecting rods 400 is arranged on one semi-circular sleeve.
