Problems solved by technology

However, there is no relatively complete water rocket launching device at present; the water rocket devices on the market generally have the following problems: first, the trajectory deviation of the water rocket is relatively large after launch, and the launch direction is uncertain during the launch process, so the experiment is difficult. To achieve the best effect; the second is that the water rocket ejection is unsuccessful or easy to fall off from the launcher, leaving hidden dangers of accidents

Abstract

The invention discloses a water rocket launching device and relates to the technical field of manufacture of experiment teaching aids. The water rocket launching device comprises a launching plate, wherein the launching plate is hinged to a seat plate through a hinged shaft; the seat plate is provided with a limiting plate on which the launching plate rotates around the hinged shaft; an inflating nozzle sheathed with a conical sealing ring is formed in the launching plate; the launching plate is provided with an arc-shaped positioning plate on one side of the inflating nozzle, at least two movable pressure rods are mounted between the positioning plate and the inflating nozzle, and an ejector is arranged on the other side of the inflating nozzle and provided with an ejector plate hinged to the launching plate, an arc-shaped clamping groove for clamping the movable pressure rod is formed in the ejector plate, and a control brake handle is connected with the ejector plate through a steel wire rope. Compared with the prior art, the water rocket launching device can be instantaneously ejected out, is high in safety and good in experiment effects.

Description

technical field [0001] The invention relates to the technical field of manufacturing experimental teaching aids, in particular to teaching aids for launching water rockets. Background technique [0002] The launch of water rockets is one of the famous cases in physics teaching. In the related scientific and technological activities of popularizing water rockets in primary and secondary schools, it is to let students better understand the phenomenon of physical recoil motion. However, there is no relatively complete water rocket launching device at present; the water rocket devices on the market generally have the following problems: first, the trajectory deviation of the water rocket is large after launch, and the launch direction is uncertain during the launch process, so the experiment is difficult. The best effect is achieved; the second is that the water rocket ejection is unsuccessful or easily falls off from the launcher, leaving hidden dangers of accidents. Contents...
