Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of building vibration isolation devices, and specifically to a building vibration isolation device. Background Technology
[0002] Currently, to prevent vibrations from equipment in buildings from damaging the building structure and disturbing the environment, vibration isolation devices are usually installed between the equipment and the building. These devices reduce the impact of vibrations from the equipment on the building, thus minimizing its effects. Vibration isolation devices are divided into active and passive isolation. Active isolation primarily reduces vibrations transmitted from machinery and equipment, such as industrial equipment, where installation of vibration isolation devices can reduce the damage to the surrounding environment and the equipment itself. Passive isolation reduces vibrations transmitted through the building foundation and equipment foundation, such as in precision instruments, broadcasting studios, recording studios, and acoustic laboratories, preventing external vibrations from affecting their internal precision environment.
[0003] Patent publication number "CN220433970U" and patent title "A Vibration Isolation Device for a Floor Building" discloses a vibration isolation device for a floor building, including a vibration damping plate, two mounting plates, and a connecting cross frame. A buffer mechanism is provided between the connecting cross frame and the vibration damping plate. The buffer mechanism includes a rotating buckle fixedly installed on the inner wall of the connecting cross frame. A cam is rotatably mounted on the outer surface of the rotating buckle, a connecting buckle is fixedly mounted on the outer surface of the cam, and a vibration transmission rod is rotatably mounted on the outer surface of the connecting buckle. A connecting column is fixedly installed on the inner top wall of the vibration damping plate, and a movable block is movably installed inside the connecting column. This vibration isolation device for a floor building, through the combined use of the buffer mechanism and vibration damping springs, achieves the purpose of buffering and damping the vibration damping plate. Compared with traditional floor buildings, it has a certain vibration isolation effect. The mounting plates can be adjusted and installed with bolts, allowing the vibration damping plate to contact the equipment on the floor building for vibration isolation, greatly protecting the service life of the floor building.
[0004] However, the vibration isolation device in this patent only uses a single vibration isolation spring for vibration isolation. Firstly, the vibration isolation effect is generally poor, and secondly, the vibration isolation effect disappears when the vibration isolation spring is damaged. Utility Model Content
[0005] The purpose of this invention is to provide a building vibration isolation device to address the aforementioned shortcomings in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A building vibration isolation device includes multiple vibration isolation components. Each vibration isolation component includes two separately arranged support parts and a central support part between the two support parts. The central support part is slidably connected to the two support parts. A first compression spring is arranged between the middle of the two support parts and the central support part. A second compression spring is arranged between the end of the central support part and the corresponding support part. A resetter is also arranged between the central support part and the two support parts.
[0008] Furthermore, the central support includes a slide rod, with two ends of the slide rod extending into two support portions respectively, and each end is fixedly connected to a sliding cover. The sliding cover is slidably connected to the corresponding support portion. A fixing plate is also fixedly provided in the middle of the slide rod. The first compression spring is disposed between the fixing plate and the support portion, and the first compression spring is interposed on the outside of the slide rod.
[0009] Furthermore, the support part includes a support plate, and a hollow support cylinder is fixedly disposed on the side of the support plate facing the slide rod. The sliding cover is slidably connected inside the support cylinder. The second compression spring is disposed between the sliding cover and the support plate, and the first compression spring is disposed between the fixed plate and the support cylinder.
[0010] Furthermore, the resetter includes four telescopic rods, with a fixed plate and a support plate respectively rotatably mounted at both ends of the telescopic rods.
[0011] Furthermore, the telescopic rod includes an outer rod rotatably connected to the support plate and an inner rod rotatably connected to the slide rod. The inner rod is slidably connected inside the outer rod, and a third compression spring is fixedly provided between the inner rod and the outer rod.
[0012] The building vibration isolation device provided by this utility model has the following beneficial effects as described above:
[0013] By setting up vibration isolation components, the two support parts are fixedly installed on the building that needs vibration isolation. When the vibration is weak, only the two second compression springs participate in vibration isolation, while when the vibration is strong, the two first compression springs also participate in vibration isolation. This can avoid the problem of easy damage to a single spring and provide corresponding vibration isolation effects according to different vibration intensities. In addition, the resetter can quickly reset the vibration isolation components after the vibration ends.

[0024] Please see Figure 1-4 A building vibration isolation device includes multiple vibration isolation components 1. Each vibration isolation component 1 includes two separately arranged support parts 2. A central support part 3 is arranged between the two support parts 2. The central support part 3 is slidably connected to the two support parts 2. A first compression spring 4 is arranged between the middle of the two support parts 2 and the central support part 3. A second compression spring 5 is arranged between the end of the central support part 3 and the corresponding support part 2. A resetter 6 is also arranged between the central support part 3 and the two support parts 2.
[0025] By using the vibration isolation component 1, the two support parts 2 are fixedly installed on the building that needs vibration isolation. When the vibration is weak, only the two second compression springs 5 participate in vibration isolation, while when the vibration is strong, the two first compression springs 4 also participate in vibration isolation. This can avoid the problem of easy damage to a single spring and provide corresponding vibration isolation effects according to different vibration intensities.
[0026] Furthermore, the central support 3 includes a slide rod 31, with two ends of the slide rod 31 extending into two support parts 2 respectively, and each end is fixedly connected to a sliding cover 32. The sliding cover 32 is slidably connected to the corresponding support part 2. A fixing plate 33 is also fixedly provided in the middle of the slide rod 31. The first compression spring 4 is provided between the fixing plate 33 and the support part 2, and the first compression spring 4 is inserted through the outside of the slide rod 31.
[0027] Furthermore, the support part 2 includes a support plate 21, and a hollow support cylinder 22 is fixedly provided on the side of the support plate 21 facing the slide rod 31. The sliding cover 32 is slidably connected inside the support cylinder 22. The second compression spring 5 is disposed between the sliding cover 32 and the support plate 21, and the first compression spring 4 is disposed between the fixed plate 33 and the support cylinder 22.
[0028] Furthermore, the resetter 6 includes four telescopic rods 61, with each end of the telescopic rod 61 rotatably mounted on the upper fixing plate 33 and the support plate 21, respectively. Each telescopic rod 61 includes an outer rod 63 rotatably connected to the support plate 21 and an inner rod 62 rotatably connected to the slide rod 31. The inner rod 62 is slidably connected inside the outer rod 63, and a third compression spring 64 is fixedly disposed between the inner rod 62 and the outer rod 63. The four telescopic rods 61 are arranged in an X-shape to facilitate rapid reset of the vibration isolation assembly 1.
[0029] Working principle:
[0030] Two support plates 21 are fixed to the building requiring vibration isolation. When the vibration is weak, only the two second compression springs 5 participate in vibration isolation through the slide rod 31. When the vibration is strong, the two support plates 21 drive the support cylinder 22 to move closer to each other, thereby contacting the first compression springs 4, so that the two first compression springs 4 also participate in vibration isolation, thus achieving a multi-stage vibration isolation effect. After the vibration ends, the resetter 6 can quickly reset the vibration isolation assembly 1.
[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
