Description

Technical Field

[0001] This utility model belongs to the field of billiard machine technology, specifically relating to a lifting device for a billiard machine. Background Technology

[0002] As a recreational device, billiard machines typically require lifting the billiard balls from their storage location to a designated height and then pushing them onto the tablecloth via a flipping mechanism. Traditional billiard machine lifting mechanisms often employ a single-stage lifting structure, resulting in limited lifting strokes that are insufficient to meet the needs of users at varying heights. Furthermore, existing lifting mechanisms often lack a stable guiding structure, making them prone to wobbling during lifting and affecting the accuracy of ball delivery. Utility Model Content

[0003] This invention overcomes the shortcomings of the prior art by proposing a lifting device for billiard machines, thus solving the problems of limited lifting stroke and instability during the lifting process of current billiard machine lifting mechanisms.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution.

A pusher frame and a flipping device are installed on the secondary lifting frame, with a synchronous belt drive enabling smooth pushing of the flipping device. This eliminates the need for an additional drive mechanism, resulting in a more compact and space-saving overall structure. Limit blocks and limit rods ensure that the lifting frame does not exceed the set range during movement, preventing mechanical interference or wire rope overload and improving equipment safety. Modular design of each component facilitates disassembly and maintenance, reducing operating costs. The motor-driven wire ropes and synchronous belts enable automated control of lifting and pushing, improving the efficiency of the billiard machine. Attached Figure Description

[0053] The flipping device 7 is “CN114570009A Flipping device for billiard balls”.

[0054] The working principle of this utility model is as follows:

[0055] When the tilting device 7 needs to be raised and pushed out, the drive motor 16 is controlled to rotate. The drive motor 16 drives the drum 2 to rotate through the synchronous belt transmission mechanism 17. The drum 2 retracts the wire rope 5, which drives the fourth pulley 21 to rise. The fourth pulley 21 drives the first-stage lifting frame 3 to rise, which in turn drives the second-stage lifting frame 4 to rise synchronously. The second-stage lifting frame 4 drives the pusher frame 6 to rise synchronously, and the pusher frame 6 drives the tilting device 7 to rise synchronously. When the first-stage lifting frame 3 rises to the point where the first limit rods 26 on both sides contact the first limit blocks 25 on the fixed frame 1, the first-stage lifting frame 3 stops rising. At this time, the wire rope 5 drives the seventh pulley 24 to rise, which in turn drives the second-stage lifting frame 4 to rise. The second-stage lifting frame 4 drives the pusher frame 6 to rise, and the pusher frame 6 drives the tilting device 7 to rise synchronously. When the second-stage lifting frame 4 rises to the point where its upper end contacts the second limit block 27 on the first-stage lifting frame 3, the second-stage lifting frame 4 stops rising, and the tilting device 7 is in place.

[0056] Then the dual-axis motor 32 starts to rotate, driving the two drive pulleys 34 to rotate. The two drive pulleys 34, through the two synchronous belts 36, drive the two driven pulleys 35 to rotate. The two synchronous belts 36, through the two connecting frames 37, drive the tilting device 7 to slide outwards towards the push frame 6.

[0057] After the flipping device 7 finishes its work, the dual-axis motor 32 rotates in the opposite direction, causing the flipping device 7 to return to the inside of the push frame 6.

[0058] Then the drive motor 16 starts to rotate in the opposite direction, causing the wire rope 5 to be released from the drum 2, causing the first-stage lifting frame 3 to begin to descend. When the lower end of the first-stage lifting frame 3 contacts the base plate 8 of the fixed frame 1, the first-stage lifting frame 3 stops descending. Then the second-stage lifting frame 4 begins to descend until the lower end of the push frame 6 contacts the base plate 8 of the fixed frame 1, at which point the push frame 6 descends to its final position, and the flipping device 7 returns to its initial position.

[0059] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.

The left and right ends of the fixed rod (30) are fixedly connected to the rear ends of the two push rods (31) respectively. The rear end of the fixed rod (30) is fixedly connected to the front end of the secondary lifting frame (4). A dual-axis motor (32) is fixedly arranged at the front end of the fixed rod (30). The two output shafts of the dual-axis motor (32) are respectively arranged on the left and right sides. A set of third sliders is arranged at the front end of the inner side of the two push rods (31). A front-back horizontal third slide rail (33) is fixedly arranged on the outer side of the left mounting plate and the right mounting plate of the flipping device (7). The two third slide rails (33) are slidably engaged with the two sets of third sliders respectively.

10. A lifting device for a billiard machine according to claim 9, characterized in that: A drive pulley (34) is rotatably mounted on the rear end of the outer side of each of the two push rods (31), and a driven pulley (35) is rotatably mounted on the front end of the outer side of each of the two push rods. The drive pulley (34) and the driven pulley (35) on the same side are connected by a synchronous belt (36). The two synchronous belts (36) are fixedly connected to the left mounting plate and the right mounting plate of the flipping device (7) through a connecting frame (37). A rotating shaft is fixedly mounted on each of the two output shafts of the dual-axis motor (32), and the ends of the two rotating shafts away from the dual-axis motor (32) are fixedly connected to the two drive pulleys (34).
