When the position of the pinball seat 9 needs adjustment, the adjusting slide 10 slides along the adjusting guide rail 8 under external force. The guide bead 1006 makes the sliding process smoother and quieter. The limiting protrusion 1004 ensures stability in the vertical direction, and the positioning screw 1003 ensures the stability of the adjusting slide 10's own structure. This allows for rapid, quiet, and stable position adjustment of the pinball seat 9 on the surface of the game table 1, increasing the diversity and fun of the game.

[0034] The adjusting guide rail 8 provides guidance for the movement of the ball seat 9. Specifically, the adjusting guide rail 8 includes a drive motor 801 and a guide belt 803. Both ends of the adjusting guide rail 8 are equipped with drive motors 801. The surface of the drive motor 801 is shafted with a guide gear 802. The surface of the adjacent guide gear 802 is sleeved with a guide belt 803. The guide belt 803 abuts against the inner side of the positioning platform 1002 and the outer side of the mounting platform 1001. The adjusting guide rail 8 provides a sliding track for the adjusting slide 10 of the ball seat 9, guiding the movement direction of the ball seat 9 on the surface of the game table 1. Both ends of the adjusting guide rail 8 have drive motors 801. The surface of the base is shafted with a guide gear 802. The surface of the adjacent guide gear 802 is sleeved with a guide belt 803. The guide belt 803 abuts against the inner side of the positioning platform 1002 and the outer side of the mounting platform 1001 of the adjusting slide 10. When the adjusting slide 10 moves, the guide belt 803 rolls on the guide rail gear 802 to reduce friction. As the ball seat 9 moves, the guide belt 803 rolls under the support of the guide rail gear 802. In conjunction with the adjusting groove 1005 of the adjusting slide 10, the ball seat 9 can move smoothly along the guide rail direction. In conjunction with the adjusting slide 10, the ball seat 9 can move smoothly, reduce friction, ensure a quiet movement, and provide reliable guidance for the position adjustment of the ball seat 9.

[0035] The ball mount 9 is in direct contact with the game ball 2, receiving and launching the game ball 2. The ball mount 9 includes a fixed base 901 and a ball arc base 902. The bottom of the fixed base 901 is connected to the adjusting slide 10. The inner wall of the adjusting arc base is provided with a guide strip 903, and the bottom surface of the guide strip 903 is provided with adjusting teeth 904.

The mounting wheel seat 908 on the bottom surface of inner wall of fixed seat 901 is connected to the driving wheel 906 and driven wheel 907 that mesh with each other. The center position of the side of driving wheel 906 is coaxially connected to half gear 905 through torsion spring. The top surface of half gear 905 abuts against adjusting tooth 904. When the drive wheel 906 rotates, the driven wheel 907 and the half gear 905 cooperate, and the half gear 905 interacts with the adjusting gear 904, causing the ball-launching seat 902 to launch. External force applied to the drive wheel 906, such as during player operation, causes the half gear 905 to interact with the adjusting gear 904 through gear transmission, driving the ball-launching seat 902 to move, thus launching the game ball 2. The ball-launching seat 9 as a whole can also move along the adjusting slide 10 on the adjusting guide rail 8, changing the launch position. The internal gear structure enables the launching of the game ball 2, and the movable design increases the game's strategic depth and fun, allowing the game ball 2 to be launched from different positions.

[0036] To facilitate the use of the game rules, control consoles 4 are set at the four corners of the game table 1. Controllers 5 are mounted on the surface of each control console 4. The connection points between adjacent sides of the game table 1 are all chamfered at a 45-degree angle to accommodate the controllers 5. This allows for easy movement of the pinball machine 9 via the drive control of the adjusting guide rails 8. Simultaneously, positioning slots 6 and positioning baffles 7 on the surface assist in positioning and dividing the game area. The controllers 5 are placed on the surface of the control consoles 4. The positioning slots 6 are used to determine the positions of other components, such as any possible auxiliary scoring devices. The two sets of positioning baffles 7 are located at the game area 3 and the edge of the game table 1, respectively, serving to divide the area. During the game… The controller 5 is electrically connected to the drive motor 801, controlling the start-up, shutdown, and rotation direction of the drive motor 801. This, in turn, drives the guide gear 802 to rotate via the output shaft of the drive motor 801, which in turn moves the guide belt 803 connected to the guide gear 802. This causes the adjusting slide 10 connected to the guide belt 803 to move synchronously, thereby controlling the left and right movement of the ball seat 9. The positioning slot 6 and the positioning baffle 7 provide clear area division and positioning reference for the game process, facilitating the statistical analysis of the game situation and improving the competitiveness of the game. The positioning slot 6 and the positioning baffle 7 make the division of the game area clearer, making it easier for players to operate and understand the game rules.

[0037] To prevent the game ball 2 from falling, a positioning slot 6 is provided on the surface of the control panel 4. A positioning baffle 7 is provided between adjacent positioning slots 6. There are two sets of positioning baffles 7, located at the edges of the game area 3 and the game table 1, respectively. The adjacent side edges of the game table 1 are the same. The adjustment guide rail 8 corresponds one-to-one with the ball seat 9 and the adjustment slide 10. The positioning baffles 7 block the game ball 2. There are two sets of positioning baffles 7. The ball seat 9 is located between the two sets of positioning baffles 7. One set located in the game area 3 is used to open and close the baffle when there is a player. If there is a player, the baffle is opened, allowing the game ball 2 to contact the ball seat 9 through the game area 3 and be launched. The other set of positioning baffles 7 is used to prevent the game ball 2 from falling off the game table 1, avoiding frequent ball picking. The positioning baffles 7 can prevent the game ball 2 from falling and can also realize the control adjustment for two, three or more people. Specific Implementation Example 2:

[0039] Reference Figure 1-13 Based on the content of the above specific embodiments, the following content is further disclosed:

[0040] In actual use, in addition to the four side structures mentioned above, the game table 1 can be set as a regular polygonal structure, such as a regular hexagon or a regular octagon. The structure of the adjustable guide rail 8, the adjustable slide 10 and the ball seat 9 remains unchanged, and the quantity and position are adapted to enable multi-player games.

[0041] In addition to the controller 5, the surface of console 4 can also hold a counter, making the game both competitive and strategic. Players can formulate game strategies by reasonably adjusting the position of the pinball seat 9 and paying attention to the counting, thus increasing the game's playability.

[0042] If the ball seat 9 is moved electrically by the controller 5, it is necessary to ensure that when the mounting platform 1001 and the positioning platform 1002 are connected to the guide belt 803, one position is fixed and the other position is slidably clamped. This is to facilitate the adjustment slide 10 to move with the guide belt 803 while using the guide belt 803 for position guidance. At this time, the inner wall of the guide belt 803 is provided with teeth that mesh with the guide rail gear 802.

[0043] If the controller 5 is not required to drive, the user can apply force to the ball seat 9 to move the ball seat 9 left and right. At this time, the inner wall of the guide belt 803 has no teeth, and the guide belt 803 and the surface of the guide rail gear 802 only perform sliding guidance. When the mounting platform 1001 and the positioning platform 1002 are connected to the guide belt 803, the two through positions maintain sliding clamping.

[0044] In summary:

[0045] The game table 1 uses an adjustable guide rail 8 on its surface, along with an adjustable slide 10 and a pinball seat 9, to launch the game ball 2 from multiple positions. The pinball seat 9 can be quickly and silently adjusted left and right on the surface of the adjustable guide rail 8 via the adjustable slide 10. The guide bead 1006 reduces friction, enabling both rapid and silent movement. This allows for quick and silent adjustment of the pinball seat 9, allowing players to quickly change its position according to the game situation, increasing the game's flexibility and fun. The silent effect also enhances the gaming experience. The positioning slot 6 and two sets of positioning baffles 7 on the surface of the control console 4 are located at the game area 3 and the edge of the game table 1, respectively, clearly defining the game area 3 and effectively preventing the game ball 2 from falling. This enables rapid ball launching and catching, helps players better understand the game rules and operations, and further optimizes the gaming experience.
