[Previous Technology] The Taiwan system is located at the boundary of stratums with frequent earthquakes. In addition to the high-rise buildings in today's society, it is very important for the earthquake-resistant work of high-rise buildings. At the same time, Taiwan ’s electronics industry has flourished. During the manufacturing process of electronic components or devices, many production equipment installations must also have vibration damping designs. Based on the above requirements for vibration reduction for high-rise buildings or production equipment, In the field of vibration reduction technology, the prevention and control of vibration energy has become an indispensable task. There are two main ways of transmission, one is to absorb vibration energy. In the existing vibration isolators, the transmission mode of vibration energy is mainly isolated, which includes a top plate, a sliding device and a bottom plate, and a sliding device is provided between the top plate and the bottom handle. The sliding device can be a rolling ball, thereby The bottom plate can produce relative horizontal movement with the top plate. At the same time, the display board system is combined with the floor or the floor of the building, and the top plate system is combined with the machine foundation or building foundation. When the vibration is transmitted from the floor or the ground to the cloud-isolator, the sliding device causes the bottom plate to move relatively horizontally with the top plate. Ding Sha helps to reduce and isolate the path of vibration transmission and achieve the effect of vibration reduction. However, the existing isolators are only reduced and isolated from the path of vibration transmission by the Qunxun Kejie device. Such a design can only have a slight effect on the M259087 vibration transmitted by the horizontal path, but the helmet method 6…, the bed effectively absorbs the vibration energy, especially the seismic energy transmitted in the vertical direction cannot be completely absorbed, so that it cannot provide a guarantee that the high-rise building or production machine will remain vertical during the earthquake. This is especially true for high-energy vibrations. It is impossible to play its due role. Therefore, the need for improvement of Ligugan M ^ Bei [New content] The author designed to improve the existing insulation Those who had problems with the vibrator, invested in research and development, and finally developed this creation. The main purpose of this creation is to provide a vibration isolator that can simultaneously achieve the dual functions of absorbing vibration energy and isolating the vibration transmission path, in order to improve the vibration reduction effect and improve the problems of the existing vibration isolators.

At the same time, more than one of the top plate, the bottom plate, and the sliding device is provided with a damping device. The damping device may be made of elastic, rubber, or a material with a better damping coefficient. With this, the specific effect achieved by this creation lies in: the concave and convex spherical arc surface matching between the upper slider and the lower slider of the slide combination device or the role of the rolling element can make the horizontal slide and vertical slide And the sliding cooperation between the sliding combination device enables the bottom plate to generate relative movement to the top plate during vibration to isolate the path of the vibration transmission (especially the horizontal transmission direction), and the damping device can effectively absorb the energy of the vibration (especially the vertical Transmission direction), which can absorb horizontal and vertical vibration energy at the same time to achieve effective vibration reduction and isolation.
