The utility model relates to an assembly type light-weight aluminum alloy carriage, and belongs to the technical field of lorry carriages. The fabricated lightweight aluminum alloy carriage comprises a wallboard assembly (1), a ceiling assembly (2), a rear door assembly (3), a side door assembly (4) and a bottom plate assembly (5), all the assemblies are in threaded connection or riveted connection and can be detached to be in a sheet shape; the aluminum alloy variable-wall-thickness bent plates are adopted, the mass of the carriage can be effectively reduced, the corrosion resistance and weather resistance of the carriage are improved, mounting and dismounting are convenient and fast, and the transportation cost is reduced through riveting and screw joint.

The utility model relates to a low-cost transmission mechanism suitable for a novel electric control booster, and belongs to the field of automobile braking systems. The controller and the cylinder body are fixedly connected with the valve body, a motor rotor of the motor is in threaded connection with the lead screw in the axial direction through a screw, the motor rotor is in small clearance fit with the rectangular tail of the lead screw in the radial direction through a rectangular hole, and the anti-rotation sleeve is in interference fit with the valve body in the radial direction and matched with the nut through a groove structure. And the piston is in threaded connection with the external thread of the nut. The anti-rotation structure has the advantages that the structure is novel, the structure that the motor rotor and the lead screw are connected through the screw and the rectangular groove and the structure that the nut and the piston are in threaded connection are adopted, the nut anti-rotation structure for converting the rotation motion of the nut into the linear motion of the piston is achieved, and connection and force transmission of the motor and the hydraulic cylinder are achieved; and meanwhile, the structure and the process are simple, the cost is low, the overall size is small after the assembly is assembled, and the loading space is saved.

The invention provides a thermal protection device of a reentry vehicle and a control method.The device comprises a gas cylinder, an adjusting valve, an angle changing module and a controller, and one end of the adjusting valve is connected with an outlet of the gas cylinder; the variable-angle module comprises a hose and a transmission mechanism, one end of the hose is connected with one end, away from the gas cylinder, of the regulating valve, one end of the transmission mechanism is connected with the hose, and the other end is connected with the regulating valve; and the controller is respectively connected with the regulating valve and the transmission mechanism. The output flow of the adjusting valve is adjusted through the transmission mechanism, more accurate jet flow can be carried out according to changes of complex flight working conditions, the aircraft has higher adaptability in the whole flight process, and meanwhile the jet flow can be saved; the jet flow angle of the hose is adjusted through the transmission mechanism, jet flow can directly face incoming flow under multiple attack angles, and the jet flow is efficiently utilized; and by integrating jet flow adjustment and jet angle adjustment, the load space is saved, and the product integration degree is improved.

The utility model relates to the technical field of regenerated composite keels, in particular to a nomadic regenerated composite keel production line quick-release workshop which is arranged on a building engineering construction site and comprises a base, a top cover, stand columns, side face upturning enclosure wallboards, end face upturning enclosure wallboards, end face door leaves, enclosure wallboard supporting legs and enclosure wallboard supporting leg inclined supporting components.
