However, the rubber plate and steel plate parts of the seismic isolation support in the prior art are fixed in height and thickness, and cannot be well applied to areas with different vibration sensations. In areas with smaller vibrations, although the seismic isolation support with a thicker and softer part can eliminate vibrations, its shaking amplitude is larger than that of the seismic isolation support with a thinner and softer part. In areas with larger vibrations, seismic isolation supports with a thicker and softer part are required to ensure the safety of the building. Summary of the invention

[0026] like Figures 1 to 7 As shown, the present invention discloses an adjustable seismic isolation support, comprising a plate-shaped upper seat 1 and a lower seat 2, referring to Figure 1 and Figure 2 This seismic isolation support is supported in the middle section of the building beam, and the upper seat 1 and the lower seat 2 are fixed by pouring, steel bars, etc.; Figure 3 and Figure 4 As shown, a disc-shaped steel plate 3 and a rubber plate 4 are sequentially stacked between the upper seat 1 and the lower seat 2, the outer diameter of the steel plate 3 is larger than the outer diameter of the rubber plate 4, and also includes a connecting ring 5, the thickness of the connecting ring 5 is thicker than the thickness of the rubber plate 4, and thinner than the superimposed thickness of the rubber plate 4 and the steel plate 3, the inner side of the connecting ring 5 is provided with a thread, the outer side of the steel plate 3 is provided with a thread, the connecting ring 5 is threadedly connected to the outer side of the steel plate 3, and the connecting ring 5 is rotated, and the connecting ring 5 can be threadedly connected to the upper and lower sides of the adjacent steel plates 3 at the same time, and the connecting ring 5 is distributed in the lower half of all steel plate 3 rubber plate 4 components.

[0027] In this scheme, by rotating the connecting ring 5, the adjacent steel plates 3 can be rigidly connected. By rotating different numbers of steel plates 3, different numbers of steel plates 3 can be rigidly connected. By connecting different numbers of steel plates 3, the length of the soft part of the seismic isolation bearing is changed. The soft parts of different lengths have different seismic isolation effects of the seismic isolation bearing. After the device is installed on the building support beam, the swingable rubber part can be adjusted to achieve different vibration response effects of the device. For example, in areas with lower vibration, fewer soft active parts can be retained to reduce the vibration amplitude of the building while ensuring the effect of buffering the vibration. In areas with higher vibration, more soft active parts can be retained to ensure buffering of larger vibrations and improve the safety of the building.

[0028] In a further solution, Figure 1 , Figure 5 and Figure 6 As shown, it also includes an adjusting portion 6, a slide groove 21 is opened on the lower seat 2, and the adjusting portion 6 includes a base 61, the base 61 is slidably arranged in the slide groove 21, and the base 61 moves along the radial direction of the steel plate 3; a first vertical plate 25 is fixed on the lower seat 2, and a screw 67 is threadedly connected on the first vertical plate 25, and a second vertical plate 611 is fixed on the base 61, and the end of the screw 67 is rotatably arranged in the second vertical plate 611, and a first spline column 62 is vertically rotatably arranged on the base 61, and a second spline column 63 is vertically fixed on the base 61, and the adjusting portion 6 also includes a top seat 68, and the top seat 68 is located at the Above the base 61, the top end of the first spline column 62 is fixed on the top seat 68, and the second spline column 63 rotates and passes through the top seat 68; a first gear 64 is vertically movable on the first spline column 62, and a slide cylinder 65 is vertically movable on the second spline column 63, and a second gear 66 is rotated outside the slide cylinder 65. When the first gear 64 and the second gear 66 are at the same height, the first gear 64 is meshed with the second gear 66. Gear teeth are provided on the outer side of the connecting ring 5. Move the base 61 and adjust the heights of the first gear 64 and the second gear 66 to make the second gear 66 meshed with the connecting ring 5.

[0029] In this scheme, by adjusting the height of the first gear 64 and the second gear 66, and rotating the screw 67 to slide the base 61, different connecting rings 5 ​​can be engaged respectively, and the connecting ring 5 can be rotated through the transmission of the first gear 64, the second gear 66 and the connecting ring 5, so that the connecting ring 5 can be easily moved up and down and connected to the adjacent steel plates 3; and through the transmission of multi-stage gears, the outer diameters of the first gear 64, the second gear 66 and the connecting ring 5 are increased successively, and when the first gear 64 is rotated by the rotating tool, a labor-saving effect can be achieved, wherein the top seat 68 and the base 61 limit the first spline column 62 and the second spline column 63 in parallel, which can achieve a better gear transmission effect.

[0030] In a further solution, Figure 6 As shown, the first spline column 62 and the second spline column 63 are both provided with hemispherical holes, and the first gear 64 and the slide cylinder 65 are both provided with elastic pins 69, and the top end of the elastic pins 69 is hemispherical.

[0031] In this solution, by providing the hemispherical hole and the elastic pin 69, the height of the first gear 64 and the second gear 66 can be temporarily fixed to avoid the first gear 64 and the second gear 66 sliding up and down and causing the transmission meshing failure.

[0032] In a further solution, Figure 1 , Figure 3 and Figure 7 As shown, a receiving tube 22 is extended downward from the bottom of the lower seat 2, and an arc-shaped clamping plate 23 is vertically slidably provided in the receiving tube 22. The outer side of the arc-shaped clamping plate 23 is threaded, and the inner side of the arc-shaped clamping plate 23 is gear-shaped to cooperate with the outer side of the connecting ring 5. A threaded column 24 is also rotatably provided on the lower seat 2, and the threaded column 24 is engaged with the outer side of the arc-shaped clamping plate 23. Rotating the threaded column 24 causes the arc-shaped clamping plate 23 to move up and down and be clamped on the outer side of the connecting ring 5.

[0033] In this solution, by rotating the threaded column 24, the arc-shaped clamping plate 23 can be moved up and down and clamp the connecting ring 5 to prevent the connecting ring 5 from rotating and displacing during vibration. The arc-shaped clamping plate 23 can also serve as a reinforcement to further strengthen the rigidly connected steel plate 3 to avoid damage to the connecting ring 5.

[0034] In a further solution, a hexagonal groove is formed at the top of the second spline column 63, and a hexagonal groove is formed at the top of the threaded column 24, so that the threaded column 24 and the second spline column 63 can be rotated by applying force to the threaded column 24 and the second spline column 63 through an electric gun and a rotating tool.
