Abstract

A javelin for children comprises a javelin head, a stabilizer and a javelin body made by expanded polyethylene, wherein the javelin head is made from ethylene-vinyl acetate copolymer or rubber to be a circular arc shape, thus reducing wind-resistance, and having moderate weight and high compact force-resistance; the stabilizer is made from XPE/IXPE to be a triangle shape, thus increasing the stability during flying. The utility model has moderate weight, is easy to master, has good stability during flying, is safe and environment friendly and can interest children for throwing javelin.

Description

Juvenile's javelin

Technical field

The utility model relates to a kind of juvenile sport apparatus, particularly a kind of juvenile's javelin.

Background technology

The problem that China teenager physique descends is on the rise, and is subjected to the great attention of country.Central authorities issue the documents successively and call the attention degree of national middle and primary schools' raising to physical education, improve the physical education method, improve teen-age physique comprehensively.And Beijing Olympic Games hold that also to manifest China's athletics race level also very weak.Improve the athletics race level of country, become real sports power, will pick up, cultivate them track-and-field interest and having deep love for from the teenager.And in the physical culture field research process of middle and primary schools, pupil particularly, because its psychology and also prematurity of physical development, control to sports apparatus is relatively poor, safety problem appears easily, directly cause traditional adult's physical culture items such as some races that comprise human basic skills, jumping, throwing to be difficult to appear on the physical education of primary school, thereby influenced teaching efficiency greatly, the example that particularly occurs safety problem in the motion of middle and primary schools' javelin is of common occurrence, cause great threat for students in middle and primary schools' life and health, also be unfavorable for popularizing of China middle and primary schools javelin motion.

The utility model content

The purpose of this utility model provide a kind of weight moderate, be easy to grasp, flight stability is good and juvenile's javelin of safety and environmental protection, uses the utility model can greatly improve the interest of juvenile to the javelin motion.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of juvenile's javelin comprises rifle head, the body of a gun and empennage, and the body of a gun is made by the polyethylene foam cotton, and the rifle head is made the head that is installed in the body of a gun by ethylene-vinyl acetate copolymer or rubber, and empennage is made the rear portion that is installed in the body of a gun by the polyethylene crosslinked foaming plate.

For further guaranteeing the security of juvenile's javelin, described rifle head is a circular shape, and can reduce windage, improves impact resistance.

The body of a gun makes tubular, can effectively control the overall weight of javelin.

Empennage is pegged graft or is bonded on the body of a gun by multi-disc triangle or isosceles trapezoid and constitutes, and is used for increasing the stability of flight.

The beneficial effects of the utility model be weight moderate, be easy to grasp, flight is far away, good, the safety and environmental protection of flight stability, and the color variation of selected environment-friendly materials, can on the basis of greatly satisfying safety, improve the interest that the pupil participates in the javelin motion, be the excellent sports apparatus of throwing exercise, also can be used as the preceding aided education of the formal javelin project of pupil.

Description of drawings

With embodiment the utility model is described in further detail with reference to the accompanying drawings below.

Fig. 1 is that the utility model is formed schematic diagram;

Fig. 2 is the utility model one specific embodiment structural representation;

Fig. 3 is the A-A view.

Among the figure:

1, rifle head; 2, the body of a gun; 3, empennage; 4, plug.

The specific embodiment

As shown in Figure 1, juvenile's javelin described in the utility model comprises rifle head 1, the body of a gun 2 and empennage 3.The material that the body of a gun 2 has adopted novel environment friendly material polyethylene foam cotton (EPE) to be commonly called as the pearl cotton is made, this kind material has that plasticity is good, toughness is strong, can reconstituted circularly, plurality of advantages such as strong, the environmental protection of crashworthiness power, has good chemical resistance simultaneously, the body of a gun made from this kind material is soft comfortable, grip good stability, simultaneously because the cotton color selectivity of pearl is many, the physilogical characteristics that can adapt to the pupil are made various color with the body of a gun, can improve the interest of juvenile to the javelin motion greatly.Rifle head 1 adopts EVA ethylene-vinyl acetate copolymer or rubber to be polished into the shape of circular arc, can reduce windage, make the javelin flying distance farther, the rifle head adopts EVA ethylene-vinyl acetate copolymer or elastomeric material to make and makes that then the nose heave amount of rifle is moderate, and wear-resisting, crashworthiness power is strong, can not cause danger on the person even when motion, collide because of carelessness yet, efficiently solve traditional javelin danger and be unsuitable for the problem that the pupil uses greatly.Empennage 3 is to be provided with for the stability that strengthens javelin flight, make the rocket tail shape, can make multi-disc, as 3 or 4, shape can be triangle or isosceles trapezoid grafting or be bonded on the body of a gun, what adopt among Fig. 1 is 4 chip isosceles trapezoid empennages, it has identical effect aspect javelin flight stable keeping, the material that empennage is selected for use is polyethylene crosslinked foaming XPE/IXPE environment-friendly materials, this kind toughness of material is strong, and is not fragile when prolonged and repeated use, and bright in luster, by the pupil is liked, can strengthen their interest greatly to the javelin motion.

As Fig. 2, shown in Figure 3, provided a kind of more concrete version, its body of a gun 2 makes tubular, long: 85cm, external diameter: 4.5cm, can effectively control the overall weight of javelin, empennage 4 combined insertings are in the body of a gun 2, and the afterbody of javelin adopts plug 4 that several sections is bonded in one.

The material that the utility model adopted all is environment-friendly materials, its purpose one is for the safety problem in the javelin motion that solves the pupil, the 2nd, can greatly improve the enjoyment of pupil's motion, anyly per capita can be easily on this basis the material in the utility model be had same or similar materials with function with other and substitute, then this simple substituting do not have novelty.
