Abstract
The utility model relates to an auxiliary training device for throwing a javelin. The auxiliary training device for throwing the javelin is characterized by comprising a telescopic short vertical rod and a telescopic long vertical rod which are arranged on the pedestals respectively, wherein the end parts of the telescopic short vertical rod and the telescopic long vertical rod are connected with a rope, and an aluminum alloy cylinder having the same diameter with a standard javelin is sleeved on the rope; the telescopic short vertical rod and the telescopic long vertical rod are composed of a plurality of bushings, the end part of each bushing is equipped with a positioning bolt, and the end parts of the aluminum alloy cylinder and the telescopic short vertical rod are connected with a spring. The heights of the two vertical rods of the auxiliary training device for throwing the javelin of the utility model can be adjusted, so that the auxiliary training device for throwing the javelin is convenient for exercising repeatedly, and helps the throwers to determine the throwing angle and height when the throwers exercise, and to control the correct postures when the throwers throw the javelin. The auxiliary training device for throwing the javelin is simple in structure and small in danger, and is convenient to use.
Description
Technical field
The utility model relates to a kind of sports training equipment, particularly a kind of supplemental training device throwing a javelin.
Background technology
Throwing belong to exercise duration short, technical strong, take absolute strength as basis, take speed as core, the high sports events of explosive force requirement.The complete skill of this project is comprised of the several indivisible technological phases of balance that maintain that grip apparatus, prepare after run-up, run-up and acceleration in advance, final force and apparatus are sold, and obtain sports achievement except having good motion function, also need to have perfect technical movements, speed and angle that wherein apparatus is sold have played key effect in throwing process.Therefore, complete technical movements become the key of throwing sports.Yet the general place of the dangerous compare great ， middle and primary schools of throwing event is less, and safety can not be guaranteed, throwing event is technical stronger simultaneously, and difficulty is large, and it is incorrect also easily injured that practitioner grasps action, add that equipment lacks, pick up back and forth equipment and lose time, affected density and intensity.For this situation, the utility model has improved the security of thrower's exercise on the basis of the every fitness of all-round developing student, technical.Strengthen density and the intensity of exercise simultaneously, made it faster and better master a skill action and minimizing exercise risk.
Summary of the invention
The utility model is in order to make up the deficiencies in the prior art, and a kind of reasonable in design, supplemental training device that structure throws a javelin is easily provided.
The utility model is achieved by the following technical solution:
A kind of supplemental training device throwing a javelin, it is characterized in that: comprise and be located at respectively flexible short stanchion and flexible long vertical rod on base, described flexible short stanchion and flexible long pole tip are connected with rope, and on described rope, cover has the aluminum alloy drum identical with regular javelin diameter.
Described flexible short stanchion and flexible long vertical rod are comprised of some sleeve pipes, and described cannula tip is provided with bolt.
The end of described aluminum alloy drum and flexible short stanchion is connected with spring.
The beneficial effects of the utility model are: two vertical rods of the trainer throwing a javelin of the present utility model are Height Adjustable, strain the rope between them, make Yi Ceyu ground that rope is low into about the angle of 40 degree, during exercise, use the pull lift action of javelin throw, aluminum alloy drum upcasts, the height judgement touching with aluminum alloy drum size firmly, because being connected with spring, the aluminum alloy drum of casting aside can be retracted immediately, conveniently repeat, while helping thrower to practise, determine angle of trajectory and height, control well and throw the correct body position of rifle.The trainer that this throws a javelin simple in structure, easy to use is dangerous little.Practitioner by throwing cylinder repeatedly, can grasp the complete skill action throwing a javelin more fast, for teacher's teaching and student's study facilitate.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
In figure, 1 base, 2 flexible short stanchions, 3 flexible long vertical rods, 4 sleeve pipes, 5 bolts, 6 ropes, 7 aluminum alloy drums, 8 springs.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described further.Accompanying drawing is specific embodiment of the utility model, this embodiment is a kind of supplemental training device throwing a javelin, it is characterized in that: comprise and be located at respectively flexible short stanchion 2 and flexible long vertical rod 3 on base 1, described flexible short stanchion 2 and flexible long vertical rod 3 ends are connected with rope 6, and on described rope 6, cover has the aluminum alloy drum 7 identical with regular javelin diameter.Described flexible short stanchion 2 and flexible long vertical rod 3 are comprised of some sleeve pipes 4, and described sleeve pipe 4 ends are provided with bolt 5.Described aluminum alloy drum 7 is connected with spring 8 with the end of flexible short stanchion 2.
Between two vertical rods of the trainer throwing a javelin of the present utility model are Height Adjustable, concrete height can be determined according to practitioner, strain the rope 6 between them, make Yi Ceyu ground that rope 6 is low into about the angle of 40 degree, during exercise, use the pull lift action of javelin throw, aluminum alloy drum 7 upcasts, the height judgement touching with aluminum alloy drum 7 size firmly, because being connected with spring 8, the aluminum alloy drum of casting aside 7 can be retracted immediately, conveniently repeat, while helping thrower to practise, determine angle of trajectory and height, control well and throw the correct body position of rifle.The trainer that this throws a javelin simple in structure, easy to use is dangerous little.Make practitioner can grasp as soon as possible and consolidate technical movements, and can improve practitioner's interest and enthusiasm, be suitable for wide popularization and application.Practitioner by throwing cylinder repeatedly, can grasp the complete skill action throwing a javelin more fast, for teacher's teaching and student's study facilitate.
