Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, specifically to an automatic ball-pushing device for billiards training. Background Technology

[0002] Billiards is an indoor skill-based sport played on a rectangular table covered with special felt and edged with rubber. Players use a cue to strike the cue ball, aiming to pocket other object balls. It combines precise geometric calculations, delicate power control, complex spin techniques, and profound tactical strategies, earning it the nickname "chess on a green chessboard." Billiards training is a systematic improvement process, focusing on repeatedly refining standard, stable striking postures and basic movements. This requires extensive practice, constantly positioning the balls for the player to strike. Traditional ball placement is usually manual, requiring someone to collect and return the struck balls, which is time-consuming and labor-intensive, hindering training efficiency. Furthermore, existing automatic ball-setting devices are often inaccurate and cannot simultaneously accommodate various ball sizes, including eight-ball and snooker balls. A new type of equipment is needed to address these issues. Utility Model Content

The drive wheel 10 is connected to the driven wheel 12 through a transmission belt 11. The driven wheel 12 is rotatably connected to the top surface of the tail end of the base plate 9. One side of the transmission belt 11 is connected to the clamp 13. The clamp 13 is fixed to the first end of the telescopic rod 5. The telescopic rod 5 is slidably connected to the limiting block 901 at the tail end of the base plate 9. The tail end of the telescopic rod 5 is connected to the stop assembly.

[0017] In this embodiment, the baffle assembly includes a back plate 19. The top of the back plate 19 is connected to the tail end of the telescopic rod 5. The back plate 19 has a square hole on its lower side and is bent into an L-shaped ball holder 1901. The inner side of the ball holder 1901 is thickened and rounded. The opening of the ball holder 1901 faces outward. The front of the back plate 19 is connected to the two side ears of the central bending groove 601 of the slide block 6. The bending groove 601 is vertically slidably connected to the third electromagnetic lock. The two sides of the third electromagnetic lock are connected to the lifting plate 21 through the support rod 20.

[0019] The working principle of this utility model is as follows: One by one, the billiard balls 2 are placed into the top plate inlet of the chassis 1. The billiard balls 2 slide down the ramp. The first billiard ball 2 is limited by the locking tongue 4 of the first electromagnetic lock. After loading, the first electromagnetic lock is opened, and the head ball slides to the locking tongue 4 of the second electromagnetic lock. Then, the first electromagnetic lock is closed to limit the subsequent billiard balls 2. When practice begins, the second electromagnetic lock is opened, and the head ball slides into the ball holder 1901 and is limited by the third electromagnetic lock. The next ball is taken to the substitute position with the cooperation of the first and second electromagnetic locks. The reduction motor 8 is started, which drives the transmission belt 11 to move. The transmission belt 11 pushes out the telescopic rod 5 through the clamp 13. The head ball in the ball holder 1901 is pushed to the hitting position. The third electromagnetic lock is opened to release the head ball. Then, the reduction motor 8 drives the guard assembly to reset. When the probe 7 detects that the head ball has been hit, the above steps are repeated to start the next round of serving.

[0020] like Figure 3 As shown, when it is necessary to change the type of serve, the lifting screw 22 and the adjusting bolt 24 are screwed together to adjust the height of each electromagnetic pin; the bolt at the arc-shaped waist hole 703 is loosened to rotate the hinge frame 701, thereby changing the detection angle of the probe 7. This utility model can accurately push the billiard ball 2 in the machine box 1 to the target position for training through the cooperation of electromagnetic locks and various components. The pushing process is monitored by the probe 7 to ensure that the billiard ball 2 in the striking position is hit by the trainee before pushing the next billiard ball 2. The height of each electromagnetic lock and the detection angle of the probe 7 in the device can be adjusted as needed, so that the device can adapt to various sizes of balls such as black eight-ball and snooker balls. It has the characteristics of being fully automatic, high-precision, and highly applicable, which greatly improves the training efficiency of billiards.
