Air pressure jet fixing base for physical experiments

Abstract

The invention discloses an air pressure jet fixing base for physical experiments. The air pressure jet fixing base comprises a bottom base, a piston rod, a transform joint, a connecting valve and an adjusting nut, wherein a pressure-bearing sleeve is arranged in the bottom base; a one-way air valve is connected above the left end of a high-pressure air pipe; fixing screws are mounted inside the left end of a connecting seat; a limit ring is arranged at the upper end of the piston rod, and a control handle is arranged above the limit ring; a high-pressure hose is connected above the transform joint; a fixing block is arranged above the connecting valve. Compared with the existing common fixing base, the air pressure jet fixing base for physical experiments has the advantages that the service performance of the whole device is effectively improved while structures are added, internal pressure of a rocket can be better controlled during the experiment, and the safety of the experiment process is improved; moreover, the base has higher stability, better attachment to the ground can be maintained, and use requirements of people are greatly improved.

Description

technical field [0001] The invention relates to the technical field of physical experiment equipment, in particular to a pneumatic jetting fixed base for physical experiments. Background technique [0002] Water rocket is a kind of rocket model that uses discarded beverage bottles as the main body of the rocket, pours one-third of the water, uses the pump to increase the internal air pressure, and the bottle rises rapidly under the reaction force. The water rocket is entertaining and educational. With high technological content, it is deeply loved by young people. [0003] However, the structure of the existing spraying experiment base is relatively simple, the explosive force of the experiment is difficult to control, and the safety is not enough, and the stability of the fixed base of the whole experimental equipment is not good, and the bonding degree with the ground during the spraying process is not good, so it cannot be well Satisfy people's experimental needs, aiming...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of air pressure injection fixed base for physical experiments, to solve the problem that the general fixed base structure proposed in the above background technology is relatively simple, the explosive force of the experiment is difficult to control, the safety is not enough, and the fixed base of the whole experimental equipment is stable. Poor performance, poor fit with the ground during the spraying process, cannot well meet people's experimental needs
