Abstract

The utility model discloses a constant temperature water jetting pneumatic model rocket. The utility model is composed of a parachute compartment, an engine compartment, and a tail fin, wherein, the parachute compartment is in detachable fit with the engine compartment, a rope is used for the connection between the parachute compartment and the engine compartment, the parachute compartment is provided with a sensor which is composed of a pressure expansion tube, a casing tube, and a spring, and the pressure expansion tube, the casing tube, and the spring are in clearance fit with each other. When the rocket is launched to the highest point, a parachute automatically expands. The sensor has the advantage of simple structure. The entire model rocket is made from plastics so that the utility model has the advantage of safety.

Description

Normal temperature, water spray aerodynamic model rocket

The utility model relates to a kind of rocket toy.

The operation principle of aerodynamic model rocket is that model rocket has an enging cabin, inject the water of some before the inherent emission in cabin, then model is contained on the launcher, in the cabin, squeeze into compressed air with inflator, water is sprayed at a high speed by the afterbody spout under compressed-air actuated effect, and model goes up to the air under the reaction force of high velocity jet water generates, is opened by timer timing controlled parachute, because timer is difficult to open parachute at the rocket flight peak, and mechanism is comparatively complicated.

The purpose of this utility model is a kind of rocket flight of design opens parachute automatically to the top model rocket, and is simple in structure.

The utility model model rocket is made up of enging cabin (7), parachute compartment (3) and empennage (10), in enging cabin (7) bottom spout (9) is arranged, and spout can be at rubber seal plug (13) jam-pack, and rubber stopper has pressure inlet on (13); Enging cabin (7) is removable the cooperation with parachute compartment (3), and there is rope to connect, one pressure expansion pipe (11) is arranged in parachute compartment (3), sleeve pipe (11) is arranged at parachute compartment (3) top, there is spring (12) expansion tube (2), sleeve pipe (11) outer ring, and expansion tube (2), sleeve pipe (3), spring (12) are matched in clearance.

Spout is that plastics are made, and enging cabin can be multistage formation, is connected by rubber tube (5) between the secondary; Pressure inlet can be bicycle valve core, and valve inside (14) is an interference fit with the rubber pipe close.

During use, model rocket is placed on the launcher (8), inject a certain amount of water to enging cabin, then with inflator to starting the gas cabin to inflate pressurization, increase with pressure, expansion tube (2) expands, laterally top pressure spring (12), spring (12) elastic force can not discharge enging cabin and parachute compartment tight fit.When pressure increases to frictional force greater than rubber stopper (13) and enging cabin (7), rubber stopper is rushed out, and with the injection backward of aqueous vapor, model rocket is flight upwards, when enging cabin pressure is zero, rocket arrives limit height, and pressure expansion pipe (2) shrinks original position, and spring (12) elastic force discharges, lander module escape engine cabin (4), connected by rope, parachute is opened, and rocket is fallen slowly.

Therefore, the utility model sensing is simple, and is handy, and integral body is made of plastics, safety.

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is the vertical view of Fig. 1.

Accompanying drawing is the utility model embodiment simultaneously, and it is made up of secondary enging cabin 4 and 7, parachute compartment (3) and empennage (10), in enging cabin (7) bottom spout (9) is arranged, and spout can be at rubber seal plug (13) jam-pack, and rubber stopper has pressure inlet on (13); Enging cabin (7) and parachute compartment (3) are for cooperating, and there is rope to connect, one pressure expansion pipe (11) is arranged in parachute compartment (3), sleeve pipe (11) is arranged at parachute compartment (3) top, there is spring (12) expansion tube (2), sleeve pipe (11) outer ring, and expansion tube (2), sleeve pipe (3), spring (12) are matched in clearance.
