Description

The water polo catapult

Technical field

The utility model relates to the catapult that a kind of amusement is used, and the plastics catapult that to refer in particular to a kind of rubber water pocket with water filling be body belongs to catapult toy field.

Background technology

The principle of catapult is identical with the principle of bow and arrow, all is to utilize ejection force to launch, and what just catapult was used is bullet, is arrow and bow and arrow is used.

Ancient book is contained: " wind-blown soil pursues for disconnected bamboo, continuous bamboo (ancient ' meat ' word)." poem is with two word short sentences and simple rhythm, write out the felling bamboo, makes catapult, penetrates bullet, hits the hunting process of birds and beasts." bullet song " may be the hominid carries out the transition to the Barbarism from the age of barbarism creation.In this case, catapult has just appearred very early the time ancient times.

According to the record of this type of data, the catapult in ancient times more is to be used for going hunting.Because the power of catapult is far short of what is expected with respect to bow and arrow, promptly be used in and go hunting, can only be the meiofauna of hunting birds and rabbit and so on also, say nothing of on a large scale and be used for military combat.But because catapult is light more portable than bow and arrow, use also more convenient, and in-plant lethality also not a little less than, therefore wider at folklore.In many kungfu novels, catapult is used as weapon by chivalrous persons.But because the function of catapult self is limit, so the influence on the China Sports history is very little, failing to step on refined taste all the time, more can only be to exist as converter tools.

Generally speaking, catapult still has certain lethality, and target can only be for object, can not be to the people.Therefore, the amusement effect of catapult also is far from developing.

Summary of the invention

The purpose of this utility model is to reduce the lethality of traditional catapult, and a kind of security that can penetrate mutually, operability and recreational all good amusement catapult are provided.

For achieving the above object, the design adopts following technical scheme:

This programme has designed a kind of water polo catapult, and a bullet pocket that can shoot ball is arranged in the middle at bowstring of traditional catapult, plays pocket and is hemispheric encirclement structure, is used to shoot.Bullet then adopts the rubber pocket of water-filling.In order to cooperate the making bullet, also specialized designs a injector.During use, an end of injector places tank, and the other end then is connected with rubber pocket, with the air bag at the moving injector of small drum middle part, in the gentle filling air inlet of water capsule, makes bullet.

Because bullet is to be made by rubber and water, in emission process, make easily and break with the direct contact of hand, therefore, in catapult hand contact when setting up a draw ring for emission, draw ring directly is connected with the rubber band of both sides as the part of bowstring, and the bullet pocket then is arranged at draw ring and rubber band gets the junction.

A kind of water polo catapult of this programme design has reduced the lethality of traditional catapult, has strengthened recreationally, and the pleasure of existing adult's sports has the pleasure of water-sprinkling concurrently, also has been full of the childlike innocence children's interesting.

Description of drawings

Fig. 1 is a present design preferred embodiment general structure schematic diagram;

Fig. 2 is a present design preferred embodiment injector structural representation.

The specific embodiment

Below adopt a preference in conjunction with the accompanying drawings the technical program to be described further:

Water polo catapult of the present utility model as shown in Figure 1, comprises bow body 1, rubber band 2, and draw ring 3 plays pocket 4, the injector 6 of bullet 5 and making bullet.The two ends that play pocket 4 are arranged at the junction of rubber band 2 and draw ring 3.

Injector 6 is by water inlet pipe 61, and air bag 62 and water injection pipe 63 are formed, and are equipped with check valve 64 in water inlet pipe 61 and the water injection pipe 63, as shown in Figure 2.During use, water inlet pipe 61 1 ends of injector 6 place tank, and water injection pipe 6 one ends then are connected with rubber pocket, with the air bag 62 at moving injector 6 middle parts of small drum, the gentle filling of water in rubber pocket, are made bullet 5.

The specification of bullet is advisable with the integral body that the bullet pocket just surrounds the contact bullet fully.

In concrete the enforcement, for easy to make, bow body 1 can adopt the unit of plastic splicing of two same moulds, and the two ends of a rubber band 2 directly lie in the branch of bow body 1, and it is roomy that the middle bifurcated of bow body is done as far as possible, is beneficial to bullet 5 and passes through.Draw ring 3 can adopt solid nylon cloth, the movable middle part that lies in two rubber bands 2, the two ends of draw ring 3, and playing pocket 4 can be the hemispherical pocket of being made by nylon cloth, and stitches on the draw ring 3 of the junction that places rubber band 2 and draw ring 3.

In order to obtain reasonable effect,, in setting in the size below the above-mentioned catapult structure, can reach reasonable effect through repetition test:

Adopt the rubber band 2 of glue pipe type, its size is external diameter 5mm, internal diameter 3mm, and length is 280mm;

The size of draw ring 3 is width 25mm, length 350mm;

Distance between two branches of bow body 1 is 150mm, highly is 180mm, and thickness is 20mm.

The side that plays pocket is parabolic shape, and size is: opening is 100mm, and the degree of depth is 73mm.

In conjunction with the accompanying drawings the utility model preferred implementation has been done detailed explanation above, but present design is not limited to above-mentioned embodiment, in the ken that those of ordinary skills possessed, can also or else break away under the prerequisite of the design's aim and make various variations.
