Embodiment Construction
[0027] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0028] Such as figure 1 As shown, it is a firing mechanism 10 according to the present invention, which includes: a first slider 11, a second slider 12 and a control dial 13 that rotates when controlled;
[0029] The first slider 11 is nested inside the second slider 12, and the first slider 11 and the second slider 12 are respectively provided with a bayonet of a preset shape. In practical applications, the bayonet For penetrating the through hole of the first slider 11 or the second slider 12, the preset shape can be as figure 1 Shown as a rectangle, it can also be a circle, an ellipse, etc. The specific shape can be based on the actual clamping of the object to be clamped. The first preset position of the contro...

The invention relates to a launching mechanism and a multi-stage water rocket. The launching mechanism comprises a first sliding block, a second sliding block and a control rotating disc which rotates when controlled. The first sliding block is arranged in the second sliding block in a nested mode, a first preset position of the control rotating disc is connected with the first sliding block, a second preset position of the control rotating disc is connected with the second sliding block, the control rotating disc drives the first sliding block and the second sliding block to slide relatively when rotating so as to increase or decrease the coincidence area of a bayonet of the first sliding block and a bayonet of the second sliding block, and thus a to-be-clamped object placed in the bayonets can be conveniently loosened or clamped. According to the launching mechanism, loosening and clamping of the object can be controlled through simple sliding, and automatic control is achieved through an external motor, so that a flight control system precisely controls launching, and the problem that the tightness degree can not be controlled in manual object clamping is solved; the launching mechanism is simple in structure and light in weight.
Description
technical field [0001] The invention relates to a launching mechanism and a multistage water rocket. Background technique [0002] The water rocket is a toy designed using mass ratio and air pressure. It is also one of the famous cases in physics teaching. It can cultivate students' interest in physics learning, and the physical principles contained in it are an important basis for understanding mechanics in physics. . [0003] Present water rocket, adopts water spray as power to promote rocket to advance, is to utilize discarded drink bottle to make power capsule, rocket body, arrow, empennage, parachute. Pour one-third of the water, use the pump to inflate the air to a certain pressure and launch it. It uses the mass ratio of water and air (the density of water is 771 times that of air), and the compressed air sprays water from the nozzle at the tail of the rocket downward at high speed. Under the reaction, the water rocket rises rapidly, with acceleration and inertia gl...
