The utility model relates to a pneumatic bowling ball gate belonging to the field of sports goods. The utility model changes the structure that a traditional bowling ball gate rotates around a vertical shaft to inwards and outwards open and close, and makes a ball gate plate quickly opened and closed. The utility model is provided with a ball gate plate (1), and the ball gate plate (1) forms corresponding right notch (7) and a left notch (8) with a ball gate (6) after closed in position; the ball gate plate (1) has an open and close structure of upper and the lower rotation, and a rotary shaft (9) of the ball gate plate (1) is horizontally arranged on the outer side surface of a wall plate (10); the tail part of the ball gate plate (1) is hinged together with a piston rod (13) of a cylinder (12) by a small shaft (11); a cylinder body of the cylinder (12) is hinged together with a small shaft (15) arranged on the wall plate (10) by a connection rod (14) of a cylinder seat. The utility model is additionally provided with a photoelectric sensing open and close mechanism (3), an emitting head (16) of the photoelectric sensing open and close mechanism (3) and a receiving head (17) are respectively arranged on the inner and the outer sides of the wall plate (10) near the ball gate (6); optical signals can reliably pass through the right notch (7), and the optical signals can be reliably blocked before balls go out of the gate. The utility model is additionally provided with corresponding air-control and electric-control systems. The utility model has the advantages of quick opening and closure of the ball gate plate (1), error action avoidance and simple structure, and the balls can be reliably prevented from going out of the ball gate (6).
