technical field

The utility model relates to a sports practice device, in particular to a triple jump practice device.

Background technique

The first jump of the triple long jump is a one-foot jump. It takes off and lands in the air with a forward swing. The take-off is powerful, the forward swing is large, and the movement is very elegant. This action is difficult and difficult for beginners to master. At present, the practice methods are limited to single-foot jumping exercises on the runway or jumping exercises with the help of pedals. Beginners have low physical fitness and poor coordination. They do not have enough time and distance to fly, and cannot complete difficult exercises. It causes beginners' movements to be tense, resulting in irregular technical movements, making it difficult to jump out of better results, and difficult to form a relaxed and smooth technical style.

Utility model content

The end of the lifting belt is fixedly connected with the pulley, the starting end of the lifting belt is connected with a protective belt, the fixed bracket at the front end of the rack is provided with a control panel, and the stepping motor and the lifting motor are respectively connected with the control panel.

The beneficial effects of the utility model are:

1. After the practitioner takes off, the lifting belt and the protective belt give the practitioner a certain amount of lifting power. When the practitioner falls after taking off, the elasticity of the lifting belt and the protective belt can slow down the falling speed of the practitioner so that they have enough time to recover. Practice technical movements;

2. The coach controls the start and stop of the stepping motor and the lifting motor through the control panel, and controls the lifting height and horizontal movement displacement of the practitioner to meet different practice needs;

3. Through the training of the triple jump practice device, the movements of the practitioner can be standardized, which is very helpful for the practitioner to form a smooth and relaxed technical style.

The gear 3 is fixedly connected to the connecting shaft 11. The rear end of the gear 3 is connected with a stepping motor 4, and the gear 3 meshes with the rack 1. The lower end of the slider 10 is horizontally hinged with a rotating shaft 12, the rotating shaft 12 is fixedly connected with a pulley 6, the rear end of the rotating shaft 12 is connected with the lifting motor 5, the lifting belt 7 is wound on the pulley 6, and the end of the lifting belt 7 is fixed with the pulley 6. Then, the starting end of the lifting belt 7 is connected with a protective belt 8, and the fixed bracket 9 at the front end of the rack 1 is provided with a control panel 13, and the stepper motor 4 and the lifting motor 5 are connected with the control panel 13 respectively.

The lifting belt 7 and the protective belt 8 are designed to be elastic, and the protective belt 8 is fixed to the waist of the practitioner. After the practitioner takes off, the coach turns on the lifting motor 5 through the control panel 13, and the lifting motor 5 drives the pulley 6 to rotate, and the lifting belt 7 is wound. On the pulley 6, the practitioner ascends, and after reaching the desired height, the stepper motor 4 is turned on, and the stepper motor 4 drives the gear 3 to rotate, the gear 3 meshes with the rack 1, and the slider 10 drives the practitioner to move backward in parallel, translation During the process, the practitioner performs movement exercises on the limbs. After moving a certain displacement, the stepper motor 4 stops rotating, the lifting motor 5 rotates in the opposite direction, and the practitioner descends to the ground, thus completing a whole set of practice process. After the exercise ended, the stepper motor 4 reversed, and the slide block 10 reset and got back to the initial position.

In this embodiment, a displacement sensor can be set on the fixed bracket 9 at the front end of the rack 1.
