Description

Technical Field

[0001] The invention specifically relates to a football shooting practice device, belonging to the technical field of football practice. Background Art

[0002] In a football game, points can only be obtained by shooting the football into the goal. When shooting, the player needs to accurately send the football into the goal and avoid the goalkeeper on the shooting path. Therefore, the shooting accuracy requirement is very high. Players need to practice a lot before they can accurately shoot the football into the goal. In the existing football shooting practice, the football needs to be placed in advance and then the players can practice shooting. The staff needs to take out the football in the goal and put it back after the player shoots to prevent the football in the goal from colliding with the shot football and affecting the shooting result. When the staff collects the football, the player needs to stop shooting to prevent the football from bouncing and injuring the staff, resulting in discontinuity in the players' shooting practice and inability to practice continuously, affecting the practice efficiency. For this reason, Chinese Patent Publication No.: CN117547793A discloses a soccer shooting training device with a soccer ball return function, comprising a base frame, the base frame is located underground, a goal is fixedly connected to the base frame, the goal is located on the ground, the base frame is symmetrically provided with fixed shells, and symmetrically distributed rodless cylinders are provided in the base frame. The structure sends the soccer ball into channels on both sides of the base frame through a rotating plate, and the soccer ball slides along the channel to a sliding plate, the sliding plate drives the soccer ball to move upward, and the push plate pushes the soccer ball out, thereby realizing the function of automatically returning the soccer ball without collecting the soccer ball, thereby ensuring the continuity of soccer shooting training; however, during training with this structure, the soccer ball cannot be sent to a designated shooting area; and when a player shoots, it is often impossible to determine whether the ball is shot into the goal from the area corresponding to the goal, and the training feedback effect is poor.
