[0002] Large ball top ball transfer entertainment game equipment is widely used in entertainment places such as video game arcades, amusement parks, shopping malls, etc. After the player starts the game by means of coin insertion or code scanning payment, etc., the large ball enters the inside of the ball blocking device from the ball inlet hole. Under the action of the driving component, the ejector rod moves up and down to lift the large ball and transfer it along a specific track. At present, the top ball on the market uses an ejector rod connected by a ring similar to a cam to push against a roller. The ejector rod is used to push and thus lift the small ball. However, the ring and the roller are only in contact connection. When the ring resets, the ejector rod may be stationary, affecting the normal lifting of the small ball. Content of the Utility Model

Specific embodiments

[0017] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific embodiments, structures, features and their effects of the present utility model as follows.

[0018] Please refer to Figures 1-3As shown in the figure, the utility model provides a stepped ball feeding structure for a game machine platform, which includes two parallel installation guard plates 1. The upper end surfaces of each installation guard plate 1 are connected with ball blocking guard plates 2. The bottom of the inner side surface of the installation guard plate 1 is installed with a limiting plate 10, and several ball pushing components are installed above the inner side surface of the installation guard plate 1. The bottoms of several ball pushing components are all connected with optical axes 11. Baffles 12 are installed at both ends of the inner side of the installation guard plate 1, and a transmission lifting component for pushing several ball pushing components to move synchronously is installed between the two baffles 12. The bottom of the optical axis 11 is rotatably installed with a lifting bearing 21. Track grooves 23 are provided on the outer surfaces of both sides of the lifting bearing 21. A limiting column 22 is slidably installed in each track groove 23. The transmission lifting component includes a plurality of rotating eccentric wheels 19. The arrangement angles of adjacent two eccentric wheels 19 are spaced 180 degrees. An annular groove cavity is provided on the outer surface of the eccentric wheel 19 and is recessed inward. Track grooves 25 are provided on the inner wall surfaces of both sides of the annular groove cavity, and the annular groove cavity is in rolling contact with the lifting bearing 21. The track groove 25 is slidably arranged with the corresponding limiting column 22. During the use process, the small balls enter from the bottom, are alternately pushed to the top height by several ball pushing components, and then enter the next action. Among them, during the lifting process, it is controlled by the rotatable eccentric wheel 19. Initially, the end of the eccentric wheel 19 connected to the lowermost ball pushing component away from the rotation center is downward, and the end of the adjacent eccentric wheel 19 away from the rotation center is upward. When the eccentric wheel 19 rotates, the other eccentric wheels 19 rotate synchronously, so as to realize the alternate lifting of the small balls. When the eccentric wheel 19 rotates, the lifting bearing 21 is in rolling contact with the annular groove cavity. Through the settings of the track groove 23 and the track groove 25, the limiting column 22 therein can slide on the eccentric wheel 19 and can also slide on the lifting bearing 21, so that the lifting bearing 21 and the eccentric wheel 19 are always together, avoiding the problem that the optical axis 11 connected to the eccentric wheel 19 is stationary and not easy to reset during the lifting and sliding process, thereby ensuring the normal operation of the lifting.

[0019] The transmission lifting component further includes a rotating shaft 18 installed between the two baffles 12. A plurality of limiting holes are provided on the outer surface of the rotating shaft 18, and a snap spring 20 is installed at the notch of the rotating shaft 18. Fixed plates 24 aligned with the limiting holes are fitted and installed on both side surfaces of the eccentric wheel 19. A motor is installed on the outer wall surface of one baffle 12, and a protective cover 13 is arranged outside the motor. In order to ensure smooth lifting, after the eccentric wheel 19 is installed on the rotating shaft 18, one end of the fixed plate 24 is attached to one side surface of the eccentric wheel 19, and the other end is aligned with the limiting hole on the rotating shaft 18, and then it is fastened. The fixed plate 24 is installed on the other side surface of the eccentric wheel 19 in the same way to increase the stability of the eccentric wheel 19.

[0020] Inside the two baffles 12 and below the rotating shaft 18, a positioning plate 14 is provided. A through groove 15 for the eccentric wheel 19 to enter is provided on the surface of the positioning plate 14. A connecting plate 16 is connected to the lower surface of the positioning plate 14. The design of the through groove 15 prevents movement interference between the eccentric wheel 19 and the positioning plate 14 during rotation.

[0021] Refer to Figure 1 As shown, the two ball blocking guards 2 are both arranged in an inclined structure. A goal hole 7 is provided on the bottom surface of one ball blocking guard 2. One end of two adjacent ball blocking guards 2 is provided with a guide plate 8. The guide plate 8 is connected to one baffle 12. A positioning block 9 is provided at the bottom of the inner wall surface of the guide plate 8. The small ball enters through the goal hole 7 and accurately enters the bottommost ball jacking assembly through the positioning block 9.

[0022] Refer to Figure 2 As shown, the ball jacking assembly includes a heightening seat 3. A flow guiding block 4 is provided on the upper surface of the heightening seat 3. A ball groove with an arc structure is provided on the upper surface of the flow guiding block 4. The upper end surface of the flow guiding block 4 is inclined to one side. The bottom surface of the heightening seat 3 is fixed to the upper end of the optical axis 11. A bearing seat 17 for the corresponding optical axis 11 to slide through is installed on the upper surface of the limiting plate 10, so as to ensure the jacking transmission of the optical axis 11. Two adjacent flow guiding blocks 4 are in a stepped shape. When the small ball enters the ball groove in the lowermost flow guiding block 4, then the transmission jacking assembly starts to work. The lowermost heightening seat 3 rises, and the height of the adjacent heightening seat 3 drops. Since the two adjacent heightening seats 3 are in close contact, the small ball in the ball groove rolls along the inclined flow guiding block 4, repeating the movement of the heightening seat 3 until the small ball is jacked up into the uppermost flow guiding block 4.

[0023] Refer to Figure 1 As shown, at the other end of two adjacent ball blocking guards 2, a flow guiding plate 5 with the same inclination angle as the flow guiding block 4 is provided. The flow guiding plate 5 is arranged in close contact with the end heightening seat 3. Small protective blocks 6 are provided at both ends of the upper surface of the flow guiding plate 5. One end of the small protective block 6 is provided with an outward opening. When the small ball enters the uppermost flow guiding block 4, it is then pushed upward by the optical axis 11 to move the corresponding heightening seat 3 upward until the height of the flow guiding block 4 is higher than the height of the flow guiding plate 5. The small ball enters the flow guiding plate 5 and enters the next action through the small protective block 6.

[0024] The working principle of the present utility model is as follows. Initially, the small ball is supported by the top ball assembly at the lowermost end. One end of the eccentric wheel 19 away from the rotation center is downward, and the end of another eccentric wheel 19 adjacent to the eccentric wheel 19 away from the rotation center is upward. The eccentric wheel 19 is driven by the rotating shaft 18 to rotate, and the rest of the eccentric wheels 19 rotate synchronously, thereby realizing the successive lifting of the small ball. When the eccentric wheel 19 rotates, the lifting bearing 21 rolls in contact with the annular groove cavity. Through the settings of the first track groove 23 and the second track groove 25, the limiting column 22 therein can slide on the eccentric wheel 19 or on the lifting bearing 21, so that the lifting bearing 21 and the eccentric wheel 19 are always together. When the eccentric wheel 19 resets, it drives the connected optical shaft 11 to slide together in the corresponding bearing seat 17, avoiding the problem that the optical shaft 11 connected to the eccentric wheel 19 is stationary and not easy to reset during the lifting and sliding process, thus ensuring the normal operation of the lifting.

Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present utility model. However, as long as it does not depart from the content of the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
