Description

Technical Field

[0001] The utility model belongs to the technical field of dampers and provides a universal viscoelastic damper. Background Art

[0002] A viscoelastic damper is a device that uses the viscoelastic properties of materials to dissipate vibration energy. It can convert mechanical vibration into heat energy, thereby reducing the system amplitude. It combines viscous damping and elastic recovery characteristics, is sensitive to frequency and temperature, and is commonly used in construction, machinery, aviation and other fields to play a role in shock absorption, seismic isolation and vibration suppression. With the continuous development of science and technology, the requirements for viscoelastic dampers are becoming higher and higher. Therefore, a universal viscoelastic damper is particularly needed.

[0003] However, most existing universal viscoelastic dampers are directly connected to adjacent pre-supported cement slabs through upper and lower connecting parts. When encountering buildings or structures with different loads and wind directions, most of them install multiple sets of viscoelastic dampers to ensure safety requirements, and set the dampers to the maximum setting range. Although this method can ensure the safety of the structure, long-term use will cause great consumption of components in the device, which can easily cause damage to the damper. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a universal viscoelastic damper to solve the problem mentioned in the above background art that the existing universal viscoelastic damper causes significant wear and tear on the components within the device after long-term use, which in turn easily causes damage to the damper.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0006] The utility model provides a universal viscoelastic damper, comprising a damping body and an adjustment mechanism disposed on at most two sides of the damping body. The adjustment mechanism comprises an inner connecting member, a threaded rod, a spring assembly, a cylinder, and an outer connecting member. The inner connecting member is used to connect to a connecting disk disposed at the end of the damping body. The inner connecting member is provided with a detachably connected threaded rod on a surface facing away from the connecting disk. The cylinder is disposed within the threaded rod, and the output end of the cylinder faces away from the threaded rod and is detachably connected to the outer connecting member. The outer connecting member is used to connect to an external component. The spring assembly is located between the inner connecting member and the outer connecting member and is sleeved onto the outside of the threaded rod. By adopting the above scheme, the performance of the damper can be adjusted to suit different working environments and load conditions by adjusting the arrangement of the threaded rod and the cylinder. Furthermore, the detachable connection between the various components facilitates maintenance and replacement, thereby reducing overall maintenance costs. Furthermore, the design of the spring assembly and the cylinder can effectively disperse and absorb vibration energy, thereby reducing component wear.

[0007] Optionally, the adjustment mechanism also includes an intermediate connecting assembly consisting of an inner connecting ring, a threaded ring, and an outer connecting ring. The threaded ring is fitted over the threaded rod and threadedly connected to it. The inner and outer connecting rings are rotatably connected at either end of the threaded ring. The inner connecting ring is positioned adjacent to the inner connector, while the outer connecting ring is positioned adjacent to the outer connector. One end of the threaded rod passes through the outer connecting ring, the threaded ring, and the inner connecting ring in sequence before connecting to the inner connector. The other end of the threaded rod is provided with a flange that abuts against the outer connecting ring. This design allows the distance between the inner and outer connecting rings to be easily adjusted by rotating the threaded ring, thereby enabling flexible adjustment of the damper's performance. This design enables the damper to maintain optimal operating conditions under varying loads and environmental conditions. Furthermore, the design of the intermediate connecting assembly makes it easier for maintenance personnel to remove and replace any damaged components without having to disassemble the entire damper. This modular design improves maintenance efficiency and reduces maintenance costs.

[0008] Optionally, the spring assembly comprises an inner spring and an outer spring, with the inner spring positioned between the inner connector and the inner connecting ring, and the outer spring positioned between the outer connector and the outer connecting ring. By providing springs on both the inner and outer sides, the inner and outer springs can jointly adjust their elastic response when external conditions change, more effectively absorbing and dissipating vibration energy. This can also effectively mitigate direct friction between the damper's internal components, reducing wear and tear, thereby extending the damper's service life.

[0009] Optionally, the spring assembly also includes an inner telescopic protective tube and an outer telescopic protective tube. The inner telescopic protective tube is mounted over the inner spring, while the outer telescopic protective tube is mounted over the outer spring. This protects the spring assembly from environmental damage, enhancing the durability of the entire damper. Furthermore, the telescopic design of the protective tube allows the spring to freely expand and contract during operation without affecting its elastic properties, while still providing necessary protection.

[0010] Optionally, the inner connecting piece and the inner connecting ring have inner threaded grooves for connecting the two ends of the inner telescopic protective tube, respectively; the outer connecting piece and the outer connecting ring have outer threaded grooves for connecting the two ends of the outer telescopic protective tube, respectively. This threaded groove design allows the inner and outer telescopic protective tubes to be securely connected to the relevant components of the damper, reducing the risk of loosening due to vibration or impact. This not only enhances the securement of the protective tubes but also improves the stability of the damper's overall structure, ensuring reliable operation under various load and vibration conditions.

[0011] The utility model discloses a beneficial effect is: the utility model discloses a universal type viscoelastic damper, through the setting of adjusting mechanism, make on the basis of original viscoelastic damper increased two adjusting parts, and then can quickly adjust the operation range of viscoelastic damper, thereby increase the flexibility when operating, and help to improve the service life of viscoelastic damper.

The objects and other advantages of the utility model can be realized and obtained by the following specification. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with specific embodiments. The accompanying drawings are for illustrative purposes only and are schematic, not actual, representations. They should not be construed as limiting this patent. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted from the drawings.

[0021] like Figure 1-5 As shown, the universal viscoelastic damper mentioned in the present invention includes a damping body 1, which is responsible for providing a viscoelastic damping effect. An adjustment mechanism 2 is set on at most two sides of the damping body 1. The adjustment mechanism 2 is composed of an inner connecting member 201, a threaded rod 203, a spring assembly, a cylinder 206, and an outer connecting member 213. The inner connecting member 201 is used to connect with the connecting disk 101 provided at the end of the damping body 1 to play a role of fixing and supporting. The inner connecting member 201 is provided with a detachable screw thread on the surface away from the connecting disk 101. The threaded rod 203 provides adjustable support. The cylinder 206, located within the threaded rod 203, adjusts the damper's operating state as needed. The cylinder's output end faces away from the threaded rod 203 and is detachably connected to the outer connector 213. The outer connector 213 is used to connect external components, ensuring effective connection between the damper and other structures. The spring assembly is located between the inner connector 201 and the outer connector 213 and is sleeved onto the outside of the threaded rod 203, providing additional elastic support and enabling automatic adjustment under different load conditions. The cylinder 206 is the power core of the entire adjustment mechanism 2. The linear motion of its output end directly drives the sliding of the outer connector 213, achieving relative position adjustment between the inner connector 201 and the outer connector 213. The stroke length of the cylinder 206 determines the maximum sliding range of the outer connector 213, thereby indirectly controlling the distance between the inner and outer connectors and preventing damage to the mechanism due to out-of-range operation. The spring assembly provides continuous support and has a certain range of travel when compressed and stretched. This range indirectly controls the adjustment range of the inner and outer connectors, preventing the mechanism from exceeding its safety limits. This utility model's universal viscoelastic damper, through its unique structural design, addresses the wear and tear that can occur with traditional dampers over long periods of use, providing an efficient and durable shock absorption solution for engineering applications.

[0022] In another embodiment, the adjustment mechanism 2 also includes an intermediate connecting assembly consisting of an inner connecting ring 207, a threaded ring 208, and an outer connecting ring 209. The threaded ring 208 is sleeved on the outside of the threaded rod 203 and threadedly connected thereto. The two ends of the threaded ring 208 are respectively provided with an inner connecting ring 207 and an outer connecting ring 209 rotatably connected thereto. The inner connecting ring 207 is arranged close to the inner connecting member 201, and the outer connecting ring 209 is arranged close to the outer connecting member 213. One end of the threaded rod 203 passes through the outer connecting ring 209, the threaded ring 208, and the inner connecting ring 207 in sequence and is connected to the inner connecting member 201. The other end of the threaded rod 203 is provided with a retaining edge 214 that is stopped on the outer connecting ring 209. In this way, the threaded ring 208 is threadedly connected to the threaded rod 203 through its internal threads to form a solid transmission structure, and the intermediate connecting component is the core component for transmitting force in the entire structure. Through its threaded structure, the rotational force of the threaded ring 208 is converted into linear movement between the inner connecting ring 207 and the outer connecting ring 209, so as to ultimately achieve the relative position adjustment of the inner connecting member 201 and the outer connecting member 213. That is, when the threaded ring 208 rotates, the threads on the threaded rod 203 cause the threaded ring 208 to move along the threaded direction of the threaded rod 203, thereby driving the relative position of the inner connecting ring 207 and the outer connecting ring 209 to change, realizing the adjustment function. The threaded ring 208 serves as the core component of the entire adjustment mechanism 2. Through its rotation, it directly controls the position change of the inner connecting ring 207 and the outer connecting ring 209, thereby indirectly affecting the relative position between the inner connecting member 201 and the outer connecting member 213. It realizes the flexibility of the adjustment range while ensuring stability during the adjustment process. It also takes into account structural stability, transmission flexibility and adjustment accuracy, ensuring reliable operation and efficient adjustment of the entire device.

[0023] In another embodiment, the spring assembly further includes an inner telescopic protection tube 205, an outer telescopic protection tube 212, an inner spring 204 and an outer spring 211, the inner spring 204 is arranged between the inner connecting member 201 and the inner connecting ring 207, the outer spring 211 is arranged between the outer connecting member 213 and the outer connecting ring 209, the inner telescopic protection tube 205 is sleeved outside the inner spring 204, and the outer telescopic protection tube 212 is sleeved outside the outer spring 211. The inner telescopic protection tube 205 and the outer telescopic protection tube 212 both have a certain telescopic ability and can The lengths of the inner and outer connecting rings 207 and 209 adjust as they slide, adapting to changes in position during adjustment. This prevents dust, dirt, or other foreign matter from entering the internal structure, thereby ensuring the device's service life and operational stability. Furthermore, the inner and outer springs 204 and 211 provide external support, guiding the springs and ensuring they remain aligned during telescopic adjustment, preventing sticking due to offset or skew. Furthermore, the springs are protected from direct exposure to external forces, potentially causing compression, pulling, or deformation. The facing surfaces of the inner connecting member 201 and the inner connecting ring 207 are provided with inner threaded grooves 202 for connecting the two ends of the inner telescopic protective tube 205. The facing surfaces of the outer connecting member 213 and the outer connecting ring 209 are provided with outer threaded grooves 210 for connecting the two ends of the outer telescopic protective tube 212.

[0024] During the adjustment process, the inner spring 204 provides a continuous supporting force for the inner connecting member 201 through its elastic force, ensuring that it remains stable in the set position. At the same time, the inner spring 204 has a certain range of travel when compressed and stretched. This range limits the movement of the inner connecting ring 207, thereby indirectly controlling the adjustment range of the inner connecting member 201 and preventing it from exceeding the safety limit of the mechanism. Finally, by cooperating with the inner telescopic protective tube 205 and the threaded rod 203, the accuracy and flexibility of the adjustment process are improved. The outer spring 211 is provided to absorb the impact and vibration of the outer connecting member 213, ensuring the stable operation of the mechanism. At the same time, the rebound effect restores the outer connecting member 213 or the outer connecting ring 209 to the initial position, limiting the displacement range of the outer connecting member 213 and preventing the mechanism from operating beyond the range.

[0025] During use, the adjustment mechanism 2 is provided at both ends or one end of the damping body 1 of the existing universal viscoelastic damper. First, the outer connecting member 213 is connected to the outer member (prefabricated cement board), and the inner connecting member 201 is connected to the connecting plate 101 of the damping body 1. When displacement occurs, the outer connecting member 213 will press the outer spring 211 and the cylinder 206, and the outer spring 211 will distribute the forces from all directions, while the cylinder 206 mainly bears the load, and the outer telescopic protective tube 212 will provide protection for the internal components; when the load is high, a wrench is used to rotate the threaded ring 208, so that the threaded ring 208 moves along the axial direction of the threaded rod 203, and the rotating threaded ring 208 drives the inner connecting ring 207 and the outer connecting ring 209 on both sides to move axially at the same time, thereby adjusting the elongation of the inner spring 204, the outer spring 211 and the cylinder 206, thereby increasing the flexibility of the mechanism.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
