The spring is supported, and the spring can generate a certain pulling force on the cover plate, which can make the cover plate open at a certain angle through the hinge and the fixing seat, which can realize the circulation of the external air and internal air of the control cabinet, which is beneficial to the heat dissipation effect.

The invention belongs to the technical field of medical devices, and specifically relates to an infusion vehicle with a retractable infusion stand. The infusion vehicle includes a vehicle body, wheels and an infusion stand; four wheels are installed at the bottom of the vehicle body, and one side of the top of the vehicle body is uniform There are multiple holes, and a ring magnet is fixed above the hole; under each hole is a telescopic cavity, and a pressure spring is installed in the telescopic cavity, and the other end of the pressure spring is connected to the electromagnet core, and the electromagnet core is fixed at the bottom of the telescopic cavity ; A conductive coil is wound around the periphery of the electromagnet core, and the two ends of the conductive coil are correspondingly connected to the positive and negative ends of the power supply box; the infusion stand includes a first movable rod, a second movable rod and an infusion hook; A second movable rod is connected, and an infusion hook is fixed above the second movable rod; a magnet is fixed below the first movable rod; and the magnet drives the infusion stand to move in the telescopic cavity. The invention can automatically shrink the infusion stand when the infusion cart is toppled over, so as to prevent the infusion stand from accidentally injuring people.

The invention discloses a multi-effect integrated kinetic energy projectile with a stepwise dissipation of impact energy, comprising a multi-effect warhead assembly, a projectile body assembly and a launching assembly. During the impact, two-stage shear failure, buffer spring limit compression and first-stage impact failure occur, dissipating a large amount of impact energy, and the multi-effect warhead assembly occurs two-stage shear failure when impacted at high speed, most of the buffer spring is compressed, and a large amount of energy is consumed. When the multi-effect warhead assembly is impacted at low speed, first-order shear failure occurs, the buffer spring is compressed in a small amount, and the impact energy is dissipated in a small amount, so that the impact energy is dissipated in a step-by-step manner. , The function of low energy consumption during long-distance low-speed impact, and under different impact conditions, it also has the triple non-lethal effects of kinetic energy strike, tear gas dispersal, and dyeing marking, which fundamentally solves the problem of active kinetic energy bombs "excessive power at close range and long distance." lack of performance".

The invention discloses a fabricated building intelligent hoisting device which comprises a base. The top of the base is rotatably connected with a support rod, the top of a fixed pulley and the leftend of the bottom of a rocker arm are fixedly connected together, a friction component is arranged on the top of a shell, a locking component is arranged at the tail end of an electric hoist, and an abutting component is arranged at the bottom of the locking component.
