Background technology

Discus throw is an event of the Olympic Games and World Track and Field Championship.When match, thrower one holds discus, Discus is thrown out by distance as far as possible by spinning movement in throwing circle.From technical pattern, complete discus throw Journey can be divided into five parts of balance after hold, poise, pre- pendulum rotation, final force and discus are thrown out.Match When discus throw, every sportsman has trial throw chance three times, and try to shoot the achievement sportsman of the first eight three times before obtaining, but also everyone It tries to shoot again three times.Current existing discus multidigit solid construction, partly uses hollow-core construction, but the two is fixed weight, The adjustable of discus weight is cannot achieve, in prolonged training process, with the use of discus, discus is because receiving weight of colliding with It can be lost, cause weight more and more lighter, also can only just eliminate the discus that old discus more renews, to cause the waste of resource, or When person's discus needs different weight in the match or training of all ages and classes and gender, it is necessary to prepare more fixed weights Discus increases trained material resources input.

Utility model content

The utility model proposes a kind of Weight-adjustable discuses can be by chamber after the weight constantly loss of discus Interior increase counter weight filler ensures that discus increases come the mechanism for keeping the consistency of weight, while multiple chambers being used to divide After counter weight filler, it can still keep balancing in the weight of each point；Or in the match or training of all ages and classes and gender It needs when different weight, it can be achieved that being adjusted for discus weight, realizes the versatility of discus, to reduce trained object Power is put into.

What the technical solution of the utility model was realized in：Weight-adjustable discus, including discus ontology, the discus The surface of ontology is equipped with perfusing hole, and the perfusing hole screw thread is equipped with pouring stopper, and the discus ontology is equipped with first chamber, described First chamber is connected to the perfusing hole, and the discus ontology is additionally provided with second chamber, third chamber, the 4th chamber and the 5th chamber Room, the second chamber and third chamber are located at the side of the first chamber, and the second chamber passes through first passage and institute First chamber connection is stated, the first passage internal thread is equipped with the first cock body, and the third chamber passes through second channel and institute First chamber connection is stated, the second channel internal thread is equipped with the second cock body；4th chamber and the 5th chamber are located at institute The other side of first chamber is stated, the 4th chamber is connected to by third channel with the first chamber, in the third channel Screw thread is equipped with third cock body, and the 5th chamber is connected to by fourth lane with the first chamber, in the fourth lane Screw thread is equipped with the 4th cock body, and the first chamber, second chamber, third chamber, the 4th chamber and the 5th chamber are perfused with Counter weight filler.

As a kind of perferred technical scheme, the second chamber is set to the top of the third chamber.

As a kind of perferred technical scheme, the 4th chamber is set to the top of the 5th chamber.

As a kind of perferred technical scheme, the second chamber setting is arranged with the 4th symmetry.

As a kind of perferred technical scheme, the third chamber setting is arranged with the 5th symmetry.

As a kind of perferred technical scheme, the counter weight filler is calcium powder.

Above-mentioned technical proposal is used, the beneficial effects of the utility model are：Due to the discus of the Weight-adjustable discus Ontology is equipped with first chamber, and second chamber is connected to by first passage with first chamber, and first passage internal thread is equipped with first Cock body, third chamber are connected to by second channel with first chamber, and second channel internal thread is equipped with the second cock body；4th chamber It is connected to first chamber by third channel, third channel internal thread is equipped with third cock body, and the 5th chamber passes through fourth lane It is connected to first chamber, it, can be according to mutual affection not to first chamber, the when discus loss in weight or when needing to adjust the weight of discus Counter weight filler is perfused in two chambers, third chamber, the 4th chamber and the 5th chamber, and the mechanism divided using multiple chambers is ensured After discus increases counter weight filler, it can still keep balancing in the weight of each point.Or the ratio of all ages and classes and gender It is needed in match or training when different weight, it can be achieved that being adjusted for discus weight, realizes the versatility of discus, to reduce The material resources input of training.
