[0002] Earthquake is a terrible natural disaster that often causes damage to buildings and other engineering facilities, and also causes serious casualties. In order to reduce the casualties and property losses caused by earthquakes, it is necessary to strengthen and improve the earthquake resistance of buildings.

[0003] The friction pendulum isolation bearing is a type of friction isolation bearing developed in the field of building structure isolation in recent years. Based on its concave geometry and surface friction characteristics, the friction pendulum allows the structure to slide on the concave surface and dissipate energy through friction when encountering earthquakes and other vibrations. Under the action of an earthquake, the isolation device absorbs seismic energy by undergoing large deformation, providing a certain amount of damping for the structure. At the same time, the structural period becomes longer, reducing the response of the upper structure.

[0004] However, the existing friction pendulum isolation bearing cannot be reset. When natural disasters such as earthquakes occur, the friction pendulum isolation bearing often needs to be reset manually after moving to a certain extent. The reset operation is complicated and consumes a lot of manpower and material resources. Therefore, how to provide a friction pendulum isolation bearing with automatic reset function is an urgent problem to be solved by technical personnel in this field. Summary of the invention

[0031] In this embodiment, the upper sliding assembly includes an upper top plate 1 and an upper top block 4. One side of the upper top plate 1 is fixedly connected to one side of the upper top block 4. An upper groove is provided on the side of the upper top block 4 away from the upper top plate 1. An upper sliding block 7 is provided in the upper groove. The upper sliding block 7 is slidably connected to the middle support plate 2 through the upper groove and the upper sliding block 7.

[0032] In this embodiment, the lower sliding assembly includes a lower top plate 3 and a lower top block 5. One side of the lower top plate 3 is fixedly connected to one side of the lower top block 5. A lower groove is provided on the side of the lower top block 5 away from the lower top plate 3. A lower sliding block 8 is provided in the lower groove. The lower sliding block 8 is slidably connected to the middle support plate 2 through the lower groove and in cooperation with the lower sliding block 8.

[0033] In this embodiment, the upper groove and the lower groove are both arc grooves, and the directions of the upper groove and the lower groove are perpendicular to each other. The upper slider 7 and the lower slider 8 are both cylindrical sliders, which can realize the sliding of the upper sliding component and the lower sliding component, and the directions of the upper groove and the lower groove are perpendicular to each other to avoid mutual influence.

[0034] In this embodiment, the reset assembly 6 includes a guide rod 10, a spring 11 and a reset combination plate, and a plurality of guide holes 15 are provided on the reset combination plate. One end of the guide rod 10 is fixed on the inner wall of the reset groove 9, and the other end of the guide rod 10 passes through the guide hole 15 of the reset combination plate and is fixed on the inner wall on the opposite side of the reset groove 9. A spring 11 is sleeved on the guide rod 10, and one end of the spring 11 is connected to one side of the reset combination plate, and the other end of the spring 11 abuts against the inner wall of the reset groove 9. When the reset combination plate is squeezed, it moves along the guide rod 10, and at the same time, the spring 11 is squeezed or pulled, and the squeezing force of the spring is used to realize the reset of the upper sliding assembly and the lower sliding assembly.

[0035] In this embodiment, the reset combination plate includes a first reset plate 13 and a second reset plate 14, and the first reset plate 13 and the second reset plate 14 are both provided with connecting holes, and the first reset plate 13 and the second reset plate 14 are fixed through the connecting holes.

The ellipsoidal slider will make the sliding direction of the upper sliding component and the lower sliding component unrestricted, and when the upper sliding component slides, it squeezes the reset combination plate at the top of the middle support plate 2, and at the same time drives the middle support plate 2 to move. At this time, the lower top block 5 in the lower sliding component will not move, and the lower top block 5 will squeeze the reset combination plate at the bottom of the middle support plate 2, and the overall bearing capacity of the seismic isolation bearing will be stronger.

Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
