Description

basketball training machine

technical field

The invention relates to a basketball training machine, which belongs to the technical field of sports equipment.

Background technique

Basketball has a high degree of appreciation and mass participation. Shooting is the most important scoring method in a basketball game, and athletes need a lot of shooting practice to improve their hit rate. Traditional shooting training is divided into self-shooting and self-grabbing and sparring-assisted training. The self-throwing and self-grabbing type wastes time and consumes physical strength, and the sparring-assisted type cannot practice by itself, which wastes human resources. At present, the basketball training machines on the market are expensive and occupy a large area, so they cannot be used for both male and female basketballs, which have a large difference in size.

In addition, the basketball launching schemes of the existing basketball training machines include high-speed cylinder pushing, high-speed cylinder kicking (using gear and rack to reduce force and speed up), spring launching and friction wheel launching. These two schemes use the cylinder to vibrate It is more serious and requires an air pump to continuously replenish the gas, which makes the noise louder and the cost is higher. Spring launches are slower and have difficulty launching beyond the three-point line. Therefore, the friction launch stands out among these several schemes, but the friction wheel launch has higher requirements on the distance, shape, and angle of the friction wheel. In addition, in the prior art, the basketball is launched by friction, which reduces the launch speed and distance of the basketball due to the friction between the friction wheel and the basketball.
