A low speed air push rod device with adjustable angle includes a launch tube, a high pressure gas storage and release device, and an overall bracket; The transmitting tube, a high-pressure gas storage and release device, and an overall bracket are connected by screws. The launch tube is provided with a vent hole, an energy absorbing device, and a piston; The vent hole is arranged on the wall of the launch tube, and the piston is connected to the push rod. There are threads in front of the piston, and there is a sealing ring in front of and behind the piston. The high-pressure gas storage and release device is composed of a gas cylinder connector and a high-pressure gas cylinder, and the function of the gas cylinder connector is to connect several gas cylinders. The overall support includes three parts: a launch tube angle adjusting device, a launch tube rack, and a support; The launch tube angle adjusting device is divided into a ball head rod, a concave head rod, and a lifting screw. The invention can adjust the launch angle through ball head rods and concave head rods, and adjust the height through lifting screws. The structure is simple and easy to assemble, which can provide a reference for high-pressure air launch devices for motion testing of large mass objects.
