Abstract:
A rolling-ball conveying device comprises balls (1), an open pipe (2), a corrugated pipe expansion joint (3), a machine housing (4), a shaft rod (6), ball accommodating wheels (7), a casing (10), a bearing (11), a ball handle (12), and a spigot-and-socket retractable pipe (13). The open pipe (2) has a fixed serpentine curve, and is connected to the corrugated pipe expansion joint (3) and the casing (10). The ball (1) and the ball handle (12) are integrated together. The ball (1) is disposed in the open pipe (2). A space of the size of the ball (1) is provided between the two ball accommodating wheels (7). When the ball accommodating wheels (7) rotate, the ball (1) is pushed into the open pipe (2), and the pushed ball (1) pushes another ball (1), and drives the ball handle (12), thereby enabling operation of the ball handle (12). The rolling-ball conveying device has a simple structure, is versatile, can be designed into multiple series of products, and can have multiple types of ball handles. On purchasing the invention, a user can determine a combination of multiple modes according to a task so as to meet requirements of different operation conditions. The invention has good retractability, compatibility, stability, and maintainability.
