[0015] Working principle: When an earthquake occurs, there will be relative displacement between the support column and the support beam, causing the nut on the short bolt to loosen, or the top of the fastening rod to be sucked into the wooden support beam, which will cause the support seat and the support beam to loosen. The support seat will repeatedly approach or move away from the support beam. At this time, the mounting seat and the push rod system are started, and the driving column pushes and pulls the pendulum rod back and forth, causing the pendulum rod to swing. During the reciprocating swing of the pendulum rod, the driving block drives the driving wheel to move back and forth synchronously. Once the driving wheel rotates, it will rotate the rotating wheel through the card block and the movable plate. When the driving wheel reverses, The card block will slide on the edge of the card slot, and will not drive the rotating wheel to rotate at this time. When the rotating wheel rotates normally, it will drive the driving rod to rotate, and then drive the worm system to work. The driving worm drives the driving worm wheel to rotate, and the driving worm wheel drives the rotating shaft to rotate. As the rotating shaft rotates, the adjusting worm also rotates, and then drives the adjusting worm wheel to rotate, and finally the adjusting bolt starts to rotate. The rotation of the adjusting bolt causes its end to rotate inside the short bolt, prompting the short bolt and the fastening rod to approach each other, thereby effectively re-tightening the connection between the support seat and the support beam and enhancing the stability of the structure.
[0016] Beneficial effects: Compared with the prior art, the present invention has the following significant features:
[0017] 1. When an earthquake occurs, the precise linkage mechanism of the seismic resistance mechanism can quickly respond and adjust the relative displacement between the support column and the support beam, effectively reducing structural vibration and enhancing the overall seismic resistance performance;
[0018] 2. When there is looseness between the support seat and the support beam, the anti-seismic mechanism can automatically start, and through the coordinated action of the swing arm, driving wheel, rotating wheel and other components, the adjusting bolt is driven to rotate, so that the short bolt and the fastening rod are close to each other, and automatic fastening is achieved to ensure structural stability;
[0019] 3. The design of the adjusting worm wheel and adjusting worm in the adjusting device enables the system to flexibly adjust the tightening force according to actual needs to adapt to different earthquake intensities and structural requirements;
[0020] 4. The detection device can monitor the relative displacement between the support seat and the support beam in real time through the swing rod, drive block and other components. Once looseness is detected, the adjustment mechanism is immediately activated to achieve intelligent response;
[0021] 5. The accommodating cavity and inspection port design inside the support beam make it easy to observe and inspect the various components of the earthquake-resistant mechanism, reducing maintenance costs and improving the reliability and service life of the system.

The short bolt 214 passes through the supporting seat 211 and the reinforcing column 212. The adjusting bolt 215 is threadedly connected to the top of the short bolt 214 for adjusting the degree of tightening. The limit block 216 is inserted into the inside of the adjusting bolt 215 to limit its rotation. The fastening rod 217 is rotatably installed on the top of the limit block 216 for further fastening the connection. The bottom and top of the reinforcing column 212 are fixedly connected to the support seat 211 through a long screw 213 and a short bolt 214 respectively. The long screw 213 and the short bolt 214 are used to connect the support column 11, the support seat 211 and the reinforcing column 212 to achieve the fastening and stability of the structure.

The surface of the adjusting bolt 215 is provided with a slide groove 2151, and the slide groove 2151 extends to the surface of the limit block 216.

The adjusting worm wheel 221 is adjusted to adjust the tightness by rotating, and the limit bar 222 rotates together with the adjusting worm wheel 221 to ensure the stability of the adjusting worm wheel 221 during the adjustment process and prevent it from over-rotating. The rotating shaft 223 provides support for the adjusting worm 224, and the adjusting worm 224 is meshed and connected with the adjusting worm wheel 221 to drive the adjusting worm wheel 221 to rotate, so as to achieve fine-tuning of the adjusting bolt 215, thereby adjusting the stiffness and damping of the anti-seismic mechanism 2. The driving rod 225 provides support for the driving worm 226. The rotating shaft 223, the driving rod 225, the driving worm 226 and the driving worm wheel 227 constitute a transmission system. By rotating the driving rod 225, the driving worm wheel 227, the rotating shaft 223 and the adjusting worm 224 are driven to rotate, thereby driving the adjusting worm wheel 221 for fine-tuning.
[0038] By setting the limit strip 222 and the slide groove 2151, the adjusting worm wheel 221 can slide on the surface of the adjusting bolt 215 and the limit block 216. By rotating the adjusting worm wheel 221, the adjusting bolt 215 can be driven to rotate. Support blocks are provided on the upper and lower sides of the adjusting worm wheel 221.

The support rod 241 is rotatably connected to the inside of the support beam 13 to provide a stable support point for the pendulum rod 242, while allowing the pendulum rod 242 to swing when an earthquake occurs. The pendulum rod 242 is fixedly connected to the outside of the support rod 241 and swings with the rotation of the support rod 241, thereby triggering the subsequent earthquake resistance mechanism through its swing. The limiting groove 244 is provided inside the swing rod 242, and the push rod 245 is slidably installed inside the limiting groove 244, providing a support point for the swing rod 242 and limiting the swing amplitude of the swing rod 242. The driving groove 247 is provided at one end of the swing rod 242, providing a sliding space for the driving block 243.

The push rod 245 is connected to the mounting seat 248 through the driving column 246.
[0040] When an earthquake occurs, relative movement occurs between the support column 11 and the support beam 13. At this time, the support seat 211 will reciprocate towards or away from the support beam 13, so that the driving column 246, with the support of the mounting seat 248 and the push rod 245, reciprocates and pushes the rocker arm 242, causing the rocker arm 242 to swing back and forth.
[0041] like Figures 10-12The rotating device 23 includes a rotating wheel 231, a driving wheel 232, a supporting shaft 233, a slot 234, a movable plate 235, a spring 236 and a block 237.

When vibrating, the detection device 24 drives the driving wheel 232 to rotate through the driving block 243, and the clamping block 237 is clamped in the clamping slot 234 to realize the synchronous rotation of the driving wheel 232 and the rotating wheel 231, so that the rotating wheel 231 drives the driving rod 225 to rotate. The spring 236 provides a restoring force for the movable plate 235 to ensure the stable clamping of the clamping block 237 in the clamping slot 234, while allowing fine adjustment when necessary. By rotating the driving rod 225, the driving worm 226 can drive the driving worm wheel 227 to rotate, so that the driving worm wheel 227 drives the rotating shaft 223 to rotate.
[0042] When an earthquake occurs, relative movement occurs between the support column 11 and the support beam 13, causing the nut on the surface of the short bolt 214 to loosen, or the end of the fastening rod 217 above is pulled into the wooden support beam 13, causing looseness between the support seat 211 and the support beam 13. At this time, rotating the adjusting bolt 215 can make the end of the adjusting bolt 215 rotate inside the short bolt 214, thereby driving the short bolt 214 and the fastening rod 217 to approach each other, thereby tightening the support seat 211 and the support beam 13 again.
