Abstract: Disclosed are a damping bearing in convertible antiseismic mode and a damping bridge apparatus. The damping bearing includes a bearing body, a damping component, a hydraulic component, and a connecting piece. The bearing body includes a first bearing, a second bearing, and a third bearing. The damping component includes an arc damping member. The arc damping member is located between the first bearing and the second bearing. One end of the arc damping member is connected to the second bearing, the other end of the arc damping member is connected to the first bearing by using the connecting piece, and after the connecting piece is cut off, the arc damping member is capable of sliding relative to the first bearing. The hydraulic component is connected to the arc damping member and the second bearing respectively.

Abstract: Disclosed is a connector for high data transfer rate, including a female element, a male element. The female element includes a housing, a plurality of sheets and a first shielding plate. The male element includes a base, a differential signal contact and a second shielding plate. At least two sheets are provided on the housing, and the first shielding plate is provided between adjacent sheets. The second shielding plate corresponding to the sheets is provided on the base. A signal pin is provided at a bottom of the sheets. The differential signal contact is provided in the base. The housing is matched with the base, and the signal pin is configured to contact the differential signal contact. The connector of the present invention improves space utilization rate in the longitudinal direction, assembly efficiency and fault tolerance rate thereof.

Abstract: The present invention provides an adaptive vibration isolator. The adaptive vibration isolator includes a hydraulic system, a first elastic member, a second elastic member, an upper top plate, and a vibration energy consumption device. The hydraulic system comprises a hydraulic cylinder, a piston and a piston rod, a first though hole is formed on the piston, and the first hydraulic chamber is communicated with the second hydraulic chamber via the first through hole. An upper top plate passes through the piston rod and the piston from the transmission portion and is connected to the vibration energy consumption device to drive the vibration energy consumption device to move relative to the piston and adjust the effective aperture of the first through hole.

Abstract: Disclosed are a sliding groove type friction pendulum high-pier bridge seismic mitigation and an isolation bearing. The bearing includes an upper connecting steel plate, a lower connecting steel plate, and a frictional sliding component clamped between the upper connecting steel plate and the lower connecting steel plate. The frictional sliding component includes an upper bearing plate, a lower bearing plate, and a hyperbolic spheroid. The upper bearing plate and the lower bearing plate are disposed on corresponding connecting steel plates, and are mounted and cooperate by using a plurality of parallel protrusions and grooves. The hyperbolic spheroid is disposed between the upper bearing plate and the lower bearing plate. A plurality of hysteretic damping components, bearing positioning structures, butterfly-shaped spring components, and bearing limiting structures are disposed on opposite surfaces of the upper bearing plate and the lower bearing plate in a circumferential direction.
