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

Embodiment Construction

[0014] The present invention will be described in further detail below with reference to the embodiments of the drawings:

[0015] Such as figure 1 with figure 2 The water rocket launching device shown includes a launching plate 2. The launching plate 2 is hinged on a seat plate 12 through a hinge shaft 1. The seat plate 12 is equipped with a limiting plate 3 for the launching plate 2 to rotate around the hinge shaft 1; on the limiting plate 3 An arc-shaped groove is provided, and a screw thread passing through the arc-shaped groove is installed on one side of the launching plate 2, and a compression nut 4 is worn on the screw, so that when the launching plate 2 is adjusted to rotate in place around the hinge axis 1, The launching plate 2 can be fixed on the limiting plate 3 by tightening the compression nut 4; the launching plate 2 is equipped with an inflator 13 with a tapered sealing ring 14, the inflator 13 passes through the trachea 9 and the pump 10 The tapered sealing rin...

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 a teaching aid for water rocket launching. 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 elementary and middle schools, it is for students to better understand the phenomenon of physical recoil motion. However, there is no relatively complete water rocket launcher at present; the water rocket devices on the market generally have the following problems: First, the trajectory of the water rocket after launch is large, and the launch direction is uncertain during the launch process, so the experiment is difficult To achieve the best results; the second is the unsuccessful ejection of the water rocket or it is easy to fall off the launcher, leaving a hidden danger of accident. Summary of the invention [0003] ...
