Description

Blue Throwing Training Equipment

technical field

The invention relates to a sports training device for ethnic minorities, in particular to a Bleu throwing training device.

Background technique

In the early days, Bulu was a tool for Mongolian hunting and herding. With the development of society, traditional nomadic hunting activities are rare, and throwing blue has gradually changed from early nomadic hunting to modern national sports competitions, but due to the lack of training for blue throwing in the existing technology Special training equipment, so athletes can't carry out targeted practice before the competition, making it difficult for athletes to obtain the best competitive performance in the competition.

Contents of the invention

Aiming at the deficiencies of the prior art, the present invention provides a training device specially for the training of blue throwing.

To achieve the above object, the present invention provides a kind of blue throwing training equipment, including blue and blue throwing training mechanism, blue throwing training mechanism includes frame, wrist strap, waist belt and pedal, described pedal The board is placed obliquely, the lower end of the pedal is hinged and fixed on the ground, and a return spring is arranged between the upper end of the pedal and the ground, and a main shaft is fixed on the frame, and the main shaft is arranged to rotate side by side. The first, second, and third pulleys, a swing arm is arranged below the main shaft, the inner end of the swing arm is hinged and fixed on the frame, the outer end of the swing arm extends outward, and a gravity plate is suspended, The wrist strap, waist belt and pedals are respectively connected to the outer end of the swing arm through the first, second and third stay cords, and the first, second and third stay cords are wound around the first, second and third pulleys respectively. A blue pull rope is connected to the blue, and a pull rope retractor for winding the blue pull rope is arranged on the frame.

The beneficial effects of the present invention are: adopting the above structure, before training, the wrist strap is bound and fixed on the trainer's wrist, and then the waist belt is bound and fixed on the trainer's waist. During training, the trainer will hold Bru in the hand bound with the wrist strap and lift Bru, then pull the body sideways and step on the pedal with one foot. After the preparation is completed, pedal the pedal Board turned quickly and threw Blu out with a flick of his arm. Because described wrist strap, waist belt and pedal are respectively connected with the swing arm that is hung with gravity plate through first, second, third stay cords, therefore be equal to above-mentioned three actions and all are to finish under the situation that load is arranged, thereby can It is very good to exercise the strength of the trainer's arms, waist and legs and the coordination of completing the above three actions at the same time, so that the trainer can throw with the best posture and power state during competition after special training. Of course, the above three actions can also be separated for separate training. At the same time, the trainer can also adjust the weight of the gravity plate according to his own strength, so as to carry out training in a more targeted manner.

In the present invention, it can be further configured that a target is set in front of the Bleu throwing training mechanism, and the target includes several upright posts erected on the ground. Setting a target will help the trainer to train more purposefully, and can effectively improve the accuracy of blue throwing.

In the present invention, it can be further set that the blue includes a rod body and a handle, the rod body is provided with a cavity, the handle is rotatably connected to the rod body, and is provided with a screw extending and inserted into the cavity, on the screw rod A nut is provided to form a threaded fit with it, and a counterweight is slidably arranged in the cavity, and the nut is axially limited and fixed on the counterweight.

With the above structure, by turning the handle, under the cooperation of the screw and the nut, the counterweight is driven to slide on the Bru rod body, so that the trainer can adjust the center of gravity of Bru according to the difference in his own force, so that Trainers can train more specifically and find the best throwing posture that suits them.

In the present invention, it can be further configured that the rod body is covered with an elastic sleeve, and the two sides of the elastic sleeve are provided with outwardly extending side wings. By setting the elastic sleeve, it can not only effectively protect Bru, but also have better resilience when Bru hits the first target to continue to hit back the follow-up targets, thus more effectively improving the accuracy and accuracy of throwing Bru. The grasp of the turning force; and the outwardly extending side wings are set on both sides of the elastic sleeve, which will help the blue to fly farther, so that the competitors can throw the blue farther to obtain better results. grades.

In the present invention, it can be further configured that a suspension ring is movably provided on the outer end of the handle, and the bulula rope is bound and fixed on the suspension ring. Such arrangement has simple structure and convenient assembly and disassembly.

The present invention can further be configured such that force measuring devices are connected between the wrist strap and the first pull cord, between the waist belt and the second pull cord, and between the pedal and the third pull cord. By setting the dynamometer, it is convenient for people to observe the trainer's exertion state more intuitively.

The present invention can further be configured such that the frame includes an upper connecting rod and a lower connecting rod, the lower connecting rod is supported and fixed on the ground, and the upper connecting rod is inserted and installed on the lower connecting rod, and can be lifted up and down relative to the lower connecting rod, The swing arm is hingedly fixed on the lower connecting rod, and an installation platform is fixedly arranged on the upper connecting rod, and the described main shaft is fixedly arranged on an installation base, and the installation base is hingedly arranged on the installation platform, and the installation platform An arc groove is also provided with the hinge point hinged with the mounting base as the center, and locking bolts for locking and fixing the mounting base and the mounting platform are provided slidingly in the circular arc groove.

Through the adjustment setting of the above structure, it is convenient for the trainer to adjust the height of the frame and the corresponding angle of the pull rope according to his own situation.
