[0002] In the prior art, the ball returning speed of bowling ball (hereinafter referred to as ball) is generally 10~14 seconds, and the ball returning device basically has two kinds, and a class discloses the scheme as Chinese patent ZL97231347.8, and its transmission mechanism is, first After the ball is raised to a certain height or squeezed to increase speed, the ball automatically returns along the return lane by its own potential energy and kinetic energy. The scheme disclosed in Chinese patent ZL01229811·5 has a new technological breakthrough for the traditional type, and has outstanding advantages. It does not need to raise the ball to a certain height, nor does it need to increase the potential energy of the ball. The extrusion type accelerates forward, the device has strong independence, strong adjustability, and is easy to install and maintain. The disadvantage is that the structure is still relatively complicated, and the speed of returning the ball is not greatly improved.
The common drawback in the prior art is that after starting up, no matter whether there is a return ball or not, the transmission mechanism is always running non-stop, so the energy consumption is high and the noise is constant.

Embodiment Construction
[0012] Further detailed description in conjunction with accompanying drawing; Among the figure, 17 shows as ball, and 27 shows as goal gate, and 28 shows as the self-control switch of goal board, and 29 shows as goal board; Fig. 1, 3 arrows show that return ball direction.
[0013] As shown in Figures 1 and 3, the fourth rotating shaft 11 and the locking lever 14 are all located below the second rotating shaft 3, and the fourth rotating shaft 11 is located on the outside of the side of the acceleration arm 1 that is opposite to the side that the acceleration arm 1 uses when hitting the ball 17. , the trigger 10 extends to the side used when the accelerator arm 1 hits the ball 17. Under the locked state of the trigger 10, the ball 17 just falls between the ball bump 12 and the lower end of the accelerator arm 1 after the ball 17 exits the ball gate 12, and touches the ball 12 There is a certain distance L, the first rotating shaft 2, the second rotating shaft 3, the third rotati...

The present invention relates to culture and sports equipment, and is especially one pneumatic bowl returning accelerator. The pneumatic driving results in simple structure, raised operation reliability, raised bowl returning speed and low power consumption. The pneumatic bowl returning accelerator has accelerating arm capable of rotating around one shaft under the action of the cylinder; rotary trigger with tongue for locking the trigger via combination with the locking rod in the accelerating arm and bowl contact; cylinder with piston rod hinged to the accelerating arm and one link rod; three rotating shafts mounted onto the wall plate; power switch; and pneumatic and electric control system. The bowl falling into the bowl returning channel knocks the bowl contact to open the trigger, so that the accelerating arm knocks the back of the bowl violently to accelerate bowl returning. The present invention has bowl returning period reduced to 6-8 sec.
