| 20120068580 | LINEAR DRIVE UNIT - A linear drive unit having a casing with top, middle and low bodies, a vertical gear, DC motor, shaft and control module. The bodies and DC motor are fitted with an O-seal. The turntable and worm are fixed at end of the shaft. A connection sit is set on the circuit wafer of the control box and has big and small contact strips, so that when the turntable is rotated, I-type conductor contacts the contact strips to generate signal connection for computation of stroke. A drive shaft is driven by the worm to rotate the worm gear cam which has a cam department that pushes L-/R-terminal for a circuit breakage, so that DC motor is stopped to control the threshold. When the cam is rotated, an inspection piece is driven to contact the circuit wafer to inspect the transmission signals, specific position and reset the specified point. | 03-22-2012 |
| 20090160273 | MAGNETIC WHEEL - The present invention provides a magnetic wheel including a foundation body, a cover body, a fly wheel, a central axis, a drive motor, a drive gear assembly and two magnetic control strips. The drive gear assembly is driven by an output axis of the drive motor, enabling the swinging of the gear wheel of two magnetic control strips. The drive gear assembly has a gearshift unit, a coupling element and rear gear. The axial direction of the coupling element and rear gear is the same as the central axis of the magnetic wheel. The gear wheel of two magnetic control strips is mated with the rear gear through spur gear, thus making it easier to improve the manufacturing precision and drive efficiency and also reduce the manufacturing cost for better economic efficiency. | 06-25-2009 |
| 20080254943 | MAGNETIC ROLLER - The present invention provides an improved structure of a magnetic roller. The magnetic roller has a pull rope brake set, mainly including left and right drive gears, both of which are assembled onto the main disk nearby the swinging end of the left and right swinging magnetic disks. The left and right drive gears are engaged through the gear tooth. The pull rope's coupling portions are assembled onto left and right drive gears corresponding separately to swinging end of left and right swinging magnetic disks. The pull rope includes first and second pull ropes, the first pull rope being used to link the pull rope's coupling portion of the left drive gear and the swinging end of right swinging magnetic disk, while the second pull rope is used to link pull rope's coupling portion of right drive gear and the swinging end of left swinging magnetic disk. | 10-16-2008 |
