This utility model discloses an automotive oil pipe with a high pressure resistance structure, relating to the field of automotive oil pipe technology. It includes a support pipe and an outer corrugated pipe. The outer corrugated pipe is adhered to the outside of the inner support pipe, and the outer corrugated pipe has an internal fitting groove. An integrally formed support strip is provided on the outside of the inner support pipe. This automotive oil pipe with a high pressure resistance structure uses cross-arranged support strips and a return spring to fill the space between the inner support pipe and the outer corrugated pipe, providing good support and high resilience, thus achieving the purpose of high pressure resistance for the automotive oil pipe. Furthermore, the outer corrugated pipe is provided with an anti-compression ring, reinforcing ribs, and connecting rings for deformation resistance, further enhancing the pressure resistance of the automotive oil pipe. This high pressure resistance structure solves the problem that existing automotive corrugated oil pipes generally rely on the corrugated structure of the pipe itself for overall structural support, resulting in poor support.

The energy dissipation capacity and the deformation capacity of the modular steel structure can be effectively improved, and the situation that the structure is damaged due to the fact that energy cannot be effectively consumed in an earthquake is avoided.

This invention relates to the field of seismic isolation and vibration reduction engineering technology, and discloses a friction pendulum bearing capable of resisting uplift forces. This friction pendulum bearing includes a liner unit, a support unit, a reset unit, and a limiting unit. The liner unit includes a steel ball-shaped liner and pressure-bearing sliding plates symmetrically arranged on the upper and lower sidewalls of the steel ball-shaped liner. The support unit includes an upper support and a lower support arranged opposite to each other, and retaining ring assemblies arranged on the opposite sidewalls of the upper and lower supports. The reset unit includes flange plates respectively arranged on the sidewalls of the upper and lower supports and a reset member connecting the opposite flange plates. The friction pendulum bearing of this invention dissipates seismic energy through the conversion of kinetic energy, potential energy, and thermal energy during frictional sliding. It has a compact overall structure, high load-bearing capacity, and can reliably withstand and transmit forces when the superstructure of a bridge or building generates forces in different directions, ensuring that it can resist uplift forces regardless of displacement in any direction.

This utility model provides a winding machine for waterproof membrane winding, belonging to the field of waterproof membrane production technology. The winding machine includes a winding machine and a roll support mechanism. A roll is installed on the left side of the inner side of the winding machine, and a feeding frame located outside the roll is installed on the top of the winding machine. A support plate is movably connected to the right side of the top of the winding machine. A support groove is opened on the rear side of the top of the support plate, and an inclined plate is fixedly connected to the left side of the support plate. An adjustment groove is opened at the bottom of the support plate. By setting up the roll support mechanism, a stable medium for supporting the roll can be formed on the top of the winding machine, ensuring that the suspended end of the roll is in a stable state during the winding operation of the waterproof membrane. This avoids the suspended end of the roll shaking during operation, which would interfere with the winding of the waterproof membrane. Therefore, the winding stability and winding effect of the winding machine and the roll are improved.
