Large-volume split-type water rocket parachute umbrella bin and water rocket

Abstract

The present invention relates to a large-volume split-type water rocket parachute umbrella bin. The umbrella bin has a bullet-shaped bin body, and the bin body is formed by connecting and combining afirst and second shells that can be opened and closed; a connecting portion connected with the top of the water rocket body is formed at the center of the bottom surface of the bin body; a surroundingrubber band is connected with the bottom of the side wall of the first shell; a mounting recess hollow toward the inner portion of the second shell is formed at the middle of the second shell; and arubber band connection and release device is arranged in the mounting recess, and the rubber band connection and release device can be connected with the movable end of the surrounding rubber band andcan release the movable end of the surrounding rubber band in due course. According to the large-volume split-type water rocket parachute umbrella bin provided by the present invention, by using thestructure, the opening manner of the bin body becomes a side opening or split type, the opening area after opening is maximized, the internal space of the bin body is completely exposed, the load in the bin body including the parachute can be opened smoothly, and the situation that the parachute cannot be opened cannot occur.

Description

Technical field: [0001] The invention relates to a water rocket which can be used as a teaching tool or a toy, in particular to a large-volume split water rocket parachute compartment and the water rocket. Background technique: [0002] Water rockets are also known as air-pressure water jet rockets and water-propelled rockets. The rapid ejection makes the arrow body obtain upward reverse thrust, and the arrow body rises and shoots out like a rocket, so it is named water rocket. [0003] Generally, the body and arrows of water rockets are made of plastic materials. In the previous use process, the water rockets often fell and broke after falling rapidly, and the phenomenon of smashing other objects or even injuring others was not guaranteed. Whether it can be reused or not can not guarantee the safety of the experiment. For this reason, some designers have designed a water rocket with a parachute, that is, connect the parachute to the upper end of the arrow body, and then t...

AI Technical Summary

Problems solved by technology

[0003] Generally, the rocket body and arrows of water rockets are made of plastic materials. In the previous use process, it often happened that the water rocket dropped rapidly and then broke on the ground, and hit other objects or even injured others. Whether it can be reused by itself, nor can it guarantee the safety of the experiment

For this reason, some designers design a water rocket with a parachute, that is, a parachute is connected to the upper end of the rocket body, and then the arrow is gently placed on the outside of the rocket body (that is, it is not tightly connected), and the arrow is tilted when the water rocket flies to a high point. Falling and releasing the parachute, but the parachute with this structure has little chance of opening, and low-angle launch cannot be achieved

[0004] The inventor once developed multiple water rocket parachute umbrella chambers. The opening methods of these umbrella chambers are that the movable part of the chamber body moves along the axial direction or flight direction of the water rocket and opens. The opening area of ​​the chamber body when it is opened is the largest. The size of the cross-section of the warehouse body, and then the parachute in the warehouse body is opened again. This method determines that the volume of the warehouse body cannot be too large and too deep, otherwise the parachute in the warehouse body cannot be opened, and other loading items cannot be added.

In addition, this kind of umbrella compartment is scattered after use, and it is inconvenient to reassemble and reuse, which brings some troubles to users.
