[0005] To achieve the above objectives, this utility model provides the following technical solution: a bridge railing anti-seismic and damping connection mechanism, comprising a connecting plate, a base fixedly connected to the bottom of the connecting plate, a first fixing bolt threadedly connected to the inner wall of the base, a railing rod movably connected to the inner wall of the connecting plate, a clamping plate movably connected to the outer wall of the railing rod, a second fixing bolt threadedly connected to the inner wall of the clamping plate, a metal plate disposed above the railing rod, the metal plate being movably connected to the inner wall of the connecting plate, and a buffer mechanism disposed on the inner wall of the metal plate.

[0006] Preferably, the guardrails are symmetrically arranged around the central axis of the plate, the plate is provided with a slide rail, and the plate is slidably connected to the guardrails.

[0007] Preferably, the metal plate is wavy and is located between the two guardrails.

[0008] Preferably, the buffer mechanism includes a damping buffer, a fixing plate, a third fixing bolt, a connector, and a buffer spring. The fixing plate is threadedly connected to the top outer wall of the damping buffer. The third fixing bolt is provided below the fixing plate and is threadedly connected to the outer wall of the damping buffer. The connector is provided below the third fixing bolt and is threadedly connected to the outer wall of the damping buffer. A buffer spring is provided on the outside of the damping buffer, and the bottom of the buffer spring is connected to a retaining plate.

[0009] Preferably, the damping buffer penetrates the metal plate and extends to the inner wall of the lower card plate, and both the metal plate and the card plate are perforated.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The bridge railing anti-vibration and shock absorption connection mechanism is installed by embedding the split railing into the card plate, which improves the strength. The corrugated metal plate in the middle disperses the longitudinal vibration energy through deformation and can elastically recover after impact, which is suitable for medium and small intensity vibration scenarios.

[0012] 2. The bridge railing's seismic damping connection mechanism, through the buffer mechanism located between the metal plate and the card plate, forms a double energy-absorbing structure that can absorb lateral impact forces. Attached Figure Description
