The sphere A is provided with an upper threaded groove, and a screw rod matching the upper thread of the groove is installed under the sphere B. hole. The utility model has the beneficial effects: simple structure, safe use, convenient operation, can effectively shorten the teaching and training cycle, improve the practice efficiency, avoid the trouble of the practitioner picking up the ball, and effectively alleviate the current problems such as the shortage of shot put teaching venues, etc. The purpose of practicing shot put is realized in a small space region.
Description
(1) technical field
The utility model relates to a kind of sports movement apparatus, particularly a kind of teaching and training shot device.
(2) background technology
In school instruction and training process, lack at present shot equipment special and place, in the throwing process, need constantly to pick up shot, not only waste time and energy, have a strong impact on and throw shot density and intensity, and injury accident easily occurs, have a strong impact on teaching and training quality.
(3) summary of the invention
The utility model provides a kind of and has significantly improved teaching and training course designing quality and exercise density, intensity, need not to pick up back and forth the teaching of ball and train the shot device in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of teaching and training shot device comprise the truth and false shot, and its special character is: the truth and false shot is connected to form one through stretch cord and the straight-bar that fixes on the ground.
Teaching of the present utility model and training shot device, the truth and false shot comprises spheroid A and organizes with it all-in-one-piece spheroid B, spheroid A is provided with the threaded groove in top, the screw rod suitable with groove top screw thread is installed below the spheroid B, has the hole of running through spheroid B on the screw rod.
Teaching of the present utility model and training shot device, straight-bar top is provided with retainer ring.
Teaching of the present utility model and training shot device, stretch cord one end are passed hole on the spheroid B and tie a knots in groove and fix, and the other end is connected and fixed ring.
Teaching of the present utility model and training shot device arrange hook between retainer ring and the stretch cord.
The beneficial effects of the utility model: the truth and false shot is connected to form one through stretch cord and the straight-bar that fixes on the ground, simple in structure, use safe, easy to operate, can effectively shorten teaching and cycle of training, improve exercise efficient, remove the trouble that the practitioner picks up ball from, the problems such as the present shot teaching lack of space of effective alleviation also can be implemented in the purpose that realizes the exercise shot in the less regional context, having saves time improves the safety coefficient of giving lessons, but automatic rebounding and move back to the truth and false shot and can significantly improve the advantages such as specific technique and sports achievement.
(4) description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1 truth and false shot, 2 stretch cords, 3 straight-bars, 4 spheroid A, 5 spheroid B, 6 grooves, 7 screw rods, 8 retainer rings, 9 hooks.
(5) specific embodiment
A kind of teaching as shown in the figure and training shot device, it comprises truth and false shot 1, truth and false shot 1 is connected to form one through stretch cord 2 and the straight-bar 3 that fixes on the ground.Truth and false shot 1 comprises spheroid A4 and organize with it all-in-one-piece spheroid B5, and spheroid A4 is provided with the threaded groove 6 in top, the screw rod 7 suitable with groove 6 top screw threads is installed below the spheroid B5, has the hole of running through spheroid B5 on the screw rod 7.Straight-bar 3 tops are provided with retainer ring 8.The hole that stretch cord 2 one ends pass on the spheroid B5 is fixed in the groove 6 interior knottings of spheroid A4, and the other end is connected and fixed ring 8.Hook 9 is set between retainer ring 8 and the stretch cord 2, hook 9 both had been convenient to fixing stretch cord 2 and had been linked up with being connected between 9, make things convenient for again when throwing truth and false shot 1, the placement of stretch cord 2, as for avoiding in the throwing process, stretch cord 2 snarls hand and damages, and will link up with 9 and place the back of the hand outside with stretch cord 2 links.
The men's shot standard weights is 7.26kg, diameter is 11-13cm, the women's shot standard weights is 4kg, diameter is 9.5-11cm, truth and false shot 1 prepares respectively by above-mentioned standard, truth and false shot 1 is comprised of spheroid B5 and spheroid A4, bore the groove 6 that diameter is 15mm at spheroid A4, groove 6 length are 30mm, and 10mm is screw thread before these groove 6 tops, screw rod 7 long 10mm below the spheroid B5, screw rod 7 open interiors, spheroid B5 is passed in this hole, and the internal diameter in hole is 6-8 mm, when assembling, stretch cord 2 is passed hole on spheroid B5 and the screw rod 7, and then knotting stretches into groove 6 with screw rod 7, by with the suitable screw thread of screw rod 7 spheroid A4 and spheroid B5 being assembled into truth and false shot 1, stretch cord 2 other ends are by linking up with on 9 retainer rings 8 that are fixed on the straight-bar 3, and this straight-bar 3 is fixed on the throwing circle limit of throwing, and stretch cord 2 length are 10-15m, diameter is 6-8mm, and the length of stretch cord 2 can also constantly change as required.
Hand-held truth and false shot 1, then truth and false shot 1 is released, stretch cord 2 can limit truth and false shot 1 and cross forward far away the rolling, and borrow the screen resilience of stretch cord 2, with 2 resiliences of truth and false shot with move back to throwing circle, when having avoided traditional throwing shot exercise, the trouble that wastes time and energy when picking up shot, improve exercise efficient, shorten teaching and cycle of training, simple in structure, use safety, and effectively alleviate the problem such as present shot teaching lack of space and also can be implemented in the purpose that realizes the exercise shot in the less regional context, having saves time improves the safety coefficient of giving lessons, but automatic rebounding and move back to shot and can significantly improve the advantages such as specific technique and sports achievement.This device also is applicable to the front throwing of the truth and false shot 1 of train athletes explosive force, rear throwing training.
