Pneumatic bowl returning accelerator

Abstract

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.

Description

technical field [0001] The invention belongs to the field of cultural and sporting goods, and relates to a pneumatic bowling return accelerating device. Background technique [0002] In the prior art, the ball returning speed of a bowling ball (hereinafter referred to as ball) is generally 10 to 14 seconds, and the ball returning device basically has two types, and a class discloses a scheme such as Chinese patent ZL97231347.8, and its transmission mechanism is, The ball is raised to a certain height first or squeezed to increase speed, and then the ball automatically returns along the fairway relying on its own potential energy and kinetic energy. Its structure is complex, high in cost, prone to failure, loud in noise, and difficult to increase the speed of returning the ball; another type For example, 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 t...

[0002] In the prior art, the ball returning speed of a bowling ball (hereinafter referred to as ball) is generally 10 to 14 seconds, and the ball returning device basically has two types, and a class discloses a scheme such as Chinese patent ZL97231347.8, and its transmission mechanism is, The ball is raised to a certain height first or squeezed to increase speed, and then the ball automatically returns along the fairway relying on its own potential energy and kinetic energy. Its structure is complex, high in cost, prone to failure, loud in noise, and difficult to increase the speed of returning the ball; another type For example, 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, and it does not need to increase the potential energy of the ball. The unique 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.
