Description

Apparatus for blasting water rocket insert in rubber packing for prevention of inflowing of extraneous matter}

The present invention relates to a water rocket launching device fitted with a rubber packing for preventing foreign matters from entering. More specifically, by inserting a rubber packing on the outer circumference of the water rocket launching unit, it is possible to block the inflow of foreign matters into the launching unit after descending, thereby preventing failure. To a water rocket launcher made.

In general, water rockets used for learning are produced by recycling PET bottles, which are mainly used for drinking water bottles. For the production of water rockets, each part (front tank, fuel container, skirt, wing) can be manufactured. Usually three to five PET bottles are used.

When the water rocket is filled with a certain amount of water in the fuel container and air is injected to unlock the fuel container inlet, the water rocket is released by the ejection of water by compressed air.It is assumed that the balance between the centerline coincidence and the wing angle attached to each part is assembled. Otherwise, the flight will not be accurate.

Conventional water rockets are described with reference to the accompanying drawings, as shown in the Utility Model Registration No. 269217, which the applicant has previously filed, the first launch unit (3) is mounted on the launch pad (2) The second launch unit 4 is fixed to the first tank 5 to be mounted on the first launch unit 3, and the second tank 6 is mounted to the second launch unit 4. .

The water rocket 1 having such a configuration is fired in the state where the first tank 5 and the second tank 6 are coupled while the first launch unit 3 is operated by the operation of the launch pad 2. The first tank 5 and the second tank 6 are separated from each other by the operation of the second firing unit 4.

At this time, when the first tank 5 is fired and descends to the bottom surface, the second launching unit 4 falls earlier than the first tank 5 by the weight of the second launching unit 4. do.

Therefore, there was a disadvantage that a failure occurs due to the inflow of soil or stones into the second launch unit (4).

Therefore, in order to compensate for the above disadvantages, the present invention can suppress the occurrence of a failure by inserting a rubber packing that can prevent the inflow of foreign substances, and also prevent the foreign matter inflow rubber packing that can further improve the learning efficiency. The purpose is to provide a water rocket launching device.

The present invention for achieving the above object is a first launching unit is mounted on the target to be launched and the second launching unit is fixed to the upper portion of the first tank to be mounted to the first launching unit, the second launching unit In the water rocket equipped with a second tank, the water rocket launch device characterized in that the rubber packing is fitted to prevent the inflow of foreign matter on the outer periphery of the first and second launching unit.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary view showing a water rocket according to the present invention,

2 is an exploded perspective view of the present invention,

3 is an exemplary cross-sectional view of the present invention.

According to the present invention, the first launching unit 20 is mounted on the launch pad 10, and the second launching unit 30 is fixed to the upper portion of the first tank 40 to be mounted to the first launching unit 20. In the water rocket 100 mounted on the second launch unit 30, the second tank 50,

The first and second firing units 20 and 30 have rubber seals 60 fitted therein so as to prevent foreign substances from entering the outer periphery of the first and second firing units 20 and 30.

The rubber packing 60 is seated on the latching jaws 21a and 31a formed at the ends of the coupling members 21 and 31 of the first and second firing units 20 and 30 to be prevented from being separated. The groove 61 is formed.

As the rubber packing 60 is seated on the firing units 20 and 30 of the water rocket 100 as described above, the water rocket 100 is dropped to the floor after firing, so that foreign matter such as soil or stone enters into the rubber packing 60. It can cut off the failure of the firing units (20, 30).

Therefore, the operation of the launch units 20 and 30 is smoothly performed, so that a wide range of experiments can be performed, thereby improving learning efficiency.

The present invention is not limited to the above-described specific preferred embodiments, and any person having ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

Therefore, the present invention can minimize the failure rate by inserting a rubber packing to block the soil or stone flowing into the launch unit in the launch unit, thereby improving the performance of the product, and also can give confidence to the user It has an effect.
