Abstract

The utility model relates to a toy. The utility model uses a plastic bottle as a rocket body, and a bottle opening is matched with a rubber stopper into which a one-way air gate valve is embedded. At operation time, half of the bottle is filled with water, and then, the bottle is aerated. When the air pressure in the bottle reaches four to five atmospheres, the rubber stopper is pushed away, and the rocket sprays water downwards while the rocket carries out launch towards the air. The utility model has the advantages of safety and repeatable use.

Description

A kind of toy rocket

The utility model relates to a kind of toy.

Traditional toy rocket is to utilize powder burning to make the rapid supercharging of air make the rocket lift-off, and the shortcoming of this toy maximum is to be with the naked light lift-off, because the direction distance of rocket is difficult to control, thereby causes fire through regular meeting, a lot of cities all forbids setting off.

It is the toy rocket of power with compressed air that the purpose of this utility model provides a kind of.

The technical solution of the utility model is such: as the rocket body, bottleneck is joined a rubber stopper with a plastic bottle, is embedded with a unidirectional valve valve in the plug.

The utility model has the advantages that: toy safety, and can use repeatedly.

Further specify the utility model and specific embodiment below by accompanying drawing.

Accompanying drawing 1, the structure chart of rubber stopper;

Accompanying drawing 2 is implemented illustration;

Accompanying drawing 3, the playing method application drawing;

Accompanying drawing 4, illustration is implemented in multistage combination;

Accompanying drawing 5, the structure chart of rubber tube joint.

Among Fig. 2, plastic bottle 1, rubber stopper 2, unidirectional valve valve 3, empennage 4, desirable one 1.5 liters plastic beverage bottle when implementing is removed the bottle lower supporter, joins a rubber stopper and causes arrow, also can load onto smoothness and the height of empennage to improve the rocket body emission at the rocket body afterbody.And rubber stopper such as Fig. 1 dig a ladder circular hole 5 in the middle of stopper, and unidirectional valve valve 3 is embedded in the small sircle hole, and during enforcement, unidirectional valve valve can be realized with the bicycle tube valve inside.

Fig. 3 is the operating process of emission " rocket ": 1/3～1/2 water of bottle volume of in plastic bottle, packing into earlier, cover tight rubber stopper 2, and body is overturn bottleneck down, pinch bottleneck with hand, keep body vertical with ground level.Be connected on the valve inside of rubber stopper with inflator then, aeration in the bottle, when the bottle internal gas pressure reached 4～5 atmospheric pressure, rubber stopper can be backed down, spray water downwards in " rocket " limit, but the limit to aerial emission upper punch to liftoff about 30 meters height.

Shown in the accompanying drawing 4, by plastic ferrule 6 they are together in series, link to each other with rubber tube joint 7 between bottle and the bottle with plural plastic bottle 1.The making of the rubber tube joint 7 of junction such as accompanying drawing 5.Respectively adorn the valve of a secondary bicycle tube at the two ends up and down of rubber tube, the valve of lower end with communicate as the plastic bottle of first order rocket body bottom.Must fill up rubber washer at lower valve tube and at bottle the end, firmly a joint bottom and a bottle end be fixed, in the long one section plastic bottle bottleneck that all inserts as the second energy rocket body in joint top.Rubbery stopper shown in Figure 1 in the still above-mentioned beyond the Great Wall single-stage water " rocket " on the nozzle of first order rocket body simultaneously.

Before the emission, pour into the clear water that accounts for its 1/3 volume in two-stage rocket body inside, in mother missile mouth nozzle, inflate then, when air pressure is atmospheric above 4, compressed gas cognition is clamp-oned in the rubber tube joint along the valve inside and the space between the valved tube of valve under the joint, rubber tube is swollen, tightly block second level rocket body, it is unlikelyly deviate from, when air pressure exceeded about 2 atmospheric pressure in the air pressure in the rubber tube joint increases to than the second level rocket body of dress water, this pressure-air can be clamp-oned in the rocket body of the second level by last valve.In the gas injection emission process, the pressure in the joint rubber tube is all the time than high about 2 atmospheric pressure of pressure in the rocket body of the second level.

After the rocket launching lift-off, following spray along with the water in the first order rocket body, the rocket body internal gas pressure just begins to descend, and the upper and lower valve of joint all is in closed condition, pressure-air in the joint rubber tube can not inject first order rocket body immediately, therefore still belong to the state of swelling, thereby two rocket bodies wouldn't be separated.

When low 2 atmospheric pressure of the pressure in of pressure drop in the first order rocket body than joint rubber, gases at high pressure in the rubber tube just clamp-on with first order rocket body in, discharge from following valve with air, rubber tube shrinks, make the first order rocket body that is close to joint hightail second level rocket body, realize that two rocket bodies separate.Do not have the second level rocket body care for and jump on recoiling, after continuing to water and spray, again upper punch a period of time, reach maximum height, free-falling at last by the following spray of water in the body.

Whole device also can use repeatedly.

Claims (2)

1, a kind of toy rocket is characterized in that: as the rocket body, bottleneck is joined a rubber stopper with plastics, is embedded with a unidirectional valve valve in the plug.

2, a kind of toy rocket according to claim 1 is characterized in that: the rocket body can be plural the plastic bottle combination, bottle with bottle between by two Non-return air valve is housed the rubber tube joint connect.
