Abstract

The invention discloses a safe water rocket launching cradle, belongs to a teaching tool, and in particular relates to a device which can demonstrate safe launching of a water rocket. The safe water rocket launching cradle disclosed by the invention comprises a base and a guide frame and is characterized in that the guide frame is composed of a front guide frame fixing ring and a rear guide frame fixing ring as well as six guide rods which are uniformly fixed at the periphery of each guide frame fixing ring, and the bottom of the rear guide frame fixing ring is arranged on a supporting upright. The safe water rocket launching cradle disclosed by the invention has the beneficial effects that the guide frame and a supporting device of the guide frame are improved, a danger caused by the fact that a sliding rail type guiding device can fly reversely is avoided, safety problem of launch crew can be well guaranteed, convenience is provided for understanding physical backflushing motion by students, and the safe water rocket launching cradle can be popularized and used in middle and primary schools.

Description

technical field [0001] The invention belongs to a teaching aid, in particular to a device capable of demonstrating safe launch of a water rocket. Background technique [0002] At present, the known water rocket launcher is a teaching equipment commonly used in physical experiments in primary and secondary schools, in order to allow students to better understand the phenomenon of physical recoil motion. Its conventional form is a guide trough formed by two guide posts, on which the water rocket is placed and launched. During the launch process, the launch direction is uncertain, and the water rocket is easy to fall off from the launcher, causing reverse flight and causing danger. Contents of the invention [0003] In order to overcome the deficiency that the existing water rocket launcher cannot ensure the launch direction and is prone to safety accidents, the present invention provides a safe water rocket launcher, which can avoid the water rocket launch from The danger o...
