Description

Technical Field

[0001] The utility model relates to the technical field of vibration isolation supports, in particular to a rubber vibration isolation support. Background Art

[0002] Rubber seismic isolation bearings are a type of shock-absorbing and noise-reducing material used in engineering structures such as buildings and bridges. Their working principle is based on the deformation of elastic materials. Rubber seismic isolation bearings are mainly made of natural rubber or synthetic rubber, and have good rigidity and flexibility. They can effectively protect and reduce shock and noise when buildings or bridges are subjected to vibration and load. Rubber seismic isolation bearings are usually installed between the bottom and foundation of the building to form an isolation layer, separating the upper structure from the foundation consolidated in the foundation, thereby blocking the propagation of seismic waves to the upper structure, which can protect both the structure and the internal equipment and instruments of the structure.

[0003] For example, a seismic isolation / vibration rubber bearing provided by patent application number CN202321134146.6 adopts a vertical vibration isolation component to penetrate a connecting hole, and the first connecting member and the second connecting member of the limiting guide component are respectively connected to the third connecting plate and the fourth connecting plate of the vertical vibration isolation component, and the free ends of the two are detachably connected in the connecting hole to constrain the horizontal movement of the vertical vibration isolation component. The constraint position is set inside the vertical vibration isolation component, which will not increase the overall cross-sectional area of ​​the bearing. Furthermore, there is no need to increase the cross-sectional area of ​​the building pier connected to the bearing.

[0004] Based on the above search and in combination with the prior art, it is found that the rubber parts of the rubber vibration isolation bearings similar to those disclosed above are mostly directly exposed to the outside world, which is easily affected by the external environment and shortens its service life. In addition, the existing rubber vibration isolation bearings are mostly integrated, which is not convenient for disassembly, assembly and replacement. Therefore, a rubber vibration isolation bearing is proposed to improve the above problems. Utility Model Content

[0030] Among them, Figure 2 As shown, a first protective ring 4 is installed at the upper end of the bottom connecting seat 1, and the rubber block 3 is located on the inner side of the first protective ring 4. A second protective ring 5 is installed at the lower end of the top connecting seat 2. The first protective ring 4 is sleeved on the outer side of the second protective ring 5.
