Description

A shot put training device

technical field

The utility model relates to the technical field of shot put training equipment, in particular to a shot put motion training device capable of quickly and efficiently training shot put throwing actions.

Background technique

Shot put is one of the throwing events of track and field sports, and it has a significant effect on enhancing physical fitness, especially developing the strength of the trunk and upper and lower limbs. Shot put is a relatively complicated technology, which needs to be completed in an instant. Therefore, shot put needs to be trained for a long time and many times. However, it takes time and energy to collect the shot put thrown during the training process, which is a waste of time and energy, and affects the training effect of the shot put movement. Moreover, the complete technique of throwing the shot put is a continuous action with aesthetic feeling, and only the whole action is reasonable. , Coordinated and coherent completion will achieve ideal results.

After searching, the utility model patent with the Chinese authorized announcement number CN205108981U and the authorized announcement date of 2016-03-30 discloses a shot put training device, including: a shot buffer net, the shot buffer net is installed on the buffer bracket, so There is a slope under the shot buffer net, and there is a gap on the slope, and a shot return device is provided at the gap, and the front end of the shot return device has an L-shaped baffle, and the L-shaped baffle There is a throwing ring at the front end of the board, and there are telescopic rods on both sides of the throwing ring, and there are elastic springs on the telescopic rods. The elastic springs are connected to the glove, and after being buffered on the shot buffer net, they enter the gap through the slope below and pass the shot. The return device returns to the original position. But there are following deficiencies: 1. Elastic spring and glove can limit throwing action, and throwing action can't be finished reasonably, coordinately, coherently, can't reach training effect; The power to enter the slope is insufficient, and it is necessary to roll to find the gap, and it is difficult to roll from the gap to the shot put return device, and the return effect is poor; 3. The protective measures are insufficient, and it is easy to hit people around; 4. It is inconvenient to carry. Therefore whether the shot put throwing action can be trained quickly and efficiently is an important criterion of the shot put training device.

Utility model content

The purpose of the utility model is to solve the shortcomings in the prior art, and propose a shot put motion training device that can quickly and efficiently train the shot put throwing action.

In order to achieve the above object, the utility model adopts the following technical solutions:

A shot put training device, comprising a base provided with a slope, the upper end of the slope is hinged with a rebound plate, a spring is arranged between the rebound plate and the base, and a rubber buffer layer is arranged on the front of the rebound plate , the upper part of the base is provided with a protective frame, the protective frame is provided with a protective net, and the slope below the rebound plate is provided with a plurality of sets of guide baffles arranged in sequence, and the guide baffles include two baffles plate, the angle between the two baffles is 90-120°, the angle between the baffle and the slope is 30-75°, the outlet of the guide baffle is provided with a chute, the The end of the chute is connected with the shot collection box, the shot collection box is fixedly connected with the front end of the base by screws, and the bottom of the base is provided with universal wheels.

Preferably, the outlet width of the guide baffle is slightly larger than the diameter of the lead ball.

Preferably, the cross section of the chute is arc-shaped.

Preferably, the four corners of the base are provided with fixing pins.

Preferably, the protective net is made of metal net.

In the utility model, the rebounding plate and the spring are used as the buffering device for the shot. The strength of the rebound after the shot hits the rebounding plate is sufficient, and the shot falls into the speed block of the slope, and the guide baffle can ensure the return of the shot to return to the shot collection. In the box, the return effect is good, the angle between the baffle and the slope is 30-75°, which can ensure that the shot will not bounce off the baffle, but fall into the chute along the inclination angle of the baffle; It is equipped with a protective frame and a protective net to avoid hitting people around; the bottom of the base is equipped with universal wheels for easy movement and transportation; the thrown shot put does not need to be time-consuming and laborious to retrieve, which improves the efficiency of training. In addition, it is compatible with the existing The difference of the shot put throwing training device is that there is no other mechanism that interferes with the throwing action, which can ensure that the entire throwing action of the trainer is completed in a reasonable, coordinated and coherent manner.
