Abstract
The utility model discloses a kind of physical education and trains special javelin, belong to sports equipment, including rubber pipette tips and barral of a gun, the rubber pipette tips include rubber base plate and rubber rifle point, and the rubber base plate is hollow structure, and rubber rifle point is assigned into the opening of rubber base plate front end, the bottom of the rubber rifle point is connected by spring with rubber base plate bottom surface, metal pedestal is installed, the rubber pipette tips can be dismantled with metal pedestal, and the rubber base plate is built with pulverized limestone between the rubber pipette tips and barral of a gun.The utility model can carry out javelin training in various places, and can effectively be judged, and reduce the danger coefficient in training process, easy to use.
Description
Technical field
The utility model belongs to sports equipment, more particularly to a kind of physical education trains special javelin.
Background technology
Javelin is always important subject in the sports curriculum of school, and existing javelin is all by the metal javelin head of cone
Formed with barral of a gun, when throwing landing, lethality is very big, potential safety hazard be present.More distinct issues are, with school in recent years
Garden infrastructure it is perfect, school playground uses artificial lawn or indoor sport shop mostly, metal pipette tips can not indoors or
Person's artificial lawn is trained, and otherwise can destroy facility, therefore can only be taken and be cancelled javelin course, or individually finds soil property behaviour
The teaching and training of field carry out javelin project.Existing product has the product that metal pipette tips are replaced using rubber pipette tips, but rubber
Pipette tips will not produce vestige when landing, it is difficult to which whether judge throws effectively.
Utility model content
In order to solve the above technical problems, the utility model, which provides a kind of physical education, trains special javelin, the javelin includes
Rubber pipette tips and barral of a gun, the rubber pipette tips include rubber base plate and rubber rifle point, and the rubber base plate is hollow structure, rubber
Rifle point is assigned into the opening of rubber base plate front end.
Further, a kind of physical education of the utility model trains special javelin, and the bottom of the rubber rifle point passes through spring
It is connected with rubber base plate bottom surface.
Further, a kind of physical education of the utility model trains special javelin, is installed between the rubber pipette tips and barral of a gun
There is metal pedestal, the rubber pipette tips can be dismantled with metal pedestal.
Further, a kind of physical education of the utility model trains special javelin, and the rubber base plate is built with pulverized limestone.
Taking the benefit of such structure has：1st, students ' physical class javelin training is no longer limited by place, no matter in hard
Playground or artificial playground all can be used, and the middle cavity and spring that rubber-sole is sat can greatly alleviate impulse force.2 take rubber pipette tips
Afterwards, the pulverized limestone of hollow intracavitary still can form vestige on ground, can effectively be judged, and be landed if not rifle point
If, rifle point can stop pulverized limestone and spill, and it is invalid can to judge throwing.3rd, danger coefficient reduces, no matter it is whole usually
During reason and human body will not be damaged in training process.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
As shown in figure 1, a kind of physical education of the utility model trains special javelin, the javelin includes rubber pipette tips 1 and rifle
Bar 2, the rubber pipette tips 1 include rubber base plate 3 and rubber rifle point 4, and the rubber base plate 3 is hollow structure, and rubber rifle point 4 is pacified
It is inserted in the opening of the front end of rubber base plate 3.
As optimization, the bottom of rubber rifle point 4 described in the utility model is connected by spring 5 with the bottom surface of rubber base plate 3.
As optimization, metal pedestal 6, the rubber rifle are installed between rubber pipette tips 1 described in the utility model and barral of a gun 2
First 1 can dismantle with metal pedestal 6.
In use, the hollow intracavitary in rubber base plate 3 loads pulverized limestone, rubber rifle point 4 assigns into the front end of rubber base plate 3
In opening, rubber rifle point 4 stops to be spilt outside pulverized limestone.When javelin lands, the effect of spring 5 has two aspects, and first aspect is limit
Position, keep rubber rifle point 4 is stable to assign on rubber base plate 3, second aspect is cushion impact forces, reduces and is rushed to ground
Hit while also protect rubber rifle point 4 to reduce abrasion.According to javelin rule, if rifle point does not land, then rubber rifle point 4 is in spring
5 supports are lower will not be in retraction rubber base plate 3, therefore the pulverized limestone of rubber-sole 3 hollow intracavitary of seat will not be spilt outside, can judge throwing
It is invalid.If rubber rifle point 4 lands, then in the meeting retraction rubber base plate 3 of rubber rifle point 4, the pulverized limestone of hollow intracavitary is because lose
Go outside the stop of rubber rifle point 4 to spill, after rubber rifle point 4 lands, rubber rifle point 4 resets under the effect of spring 5, without throwing every time
Manually resetted after throwing.Metal pedestal 6 is installed between barral of a gun 2 and rubber pipette tips 1, pipette tips weight can be increased, also beneficial to rubber
The replacing of glue base 3.
