20120096963 | ELECTRIC PUSH ROD AND RELEASE MECHANISM COMBINATION STRUCTURE - An electric push rod and release mechanism combination structure includes an electric push rod assembly using a coupling for connection to movable frame parts of an equipment and a motor to rotate a transmission screw rod through a reducing gear set in moving a retractable tube set between an extended position and a received position, and a release mechanism consisting of a mounting socket, a connection socket, a torsion spring, a clutch module and an operating device and connected between the retractable tube set and the coupling of the electric push rod assembly for operation by a user to release the retractable tube set from the coupling safely with less effort. | 04-26-2012 |
20100155680 | QUICK RISING SUPPORTING DEVICE - A quick rising supporting device includes a bar having a first threaded portion and a second threaded portion on the two sides respectively with a first connecting block and a second connecting block, and an axial portion on top of a supporting arm and a swing arm forming a Y shape bar are respectively axially connected to the first and second connecting blocks. A sliding block is formed on a side of the first connection block. The translatory shift of the bar on the second connecting block motivates the first connecting block to move in same direction when the bar rotates, the first connecting block is led by the first threaded portion to rotate and move forward to achieve the dual displacement speed of the supporting device. When the closed supporting arm and the swing arm bias and swing to open, only biasing and swinging of the supporting arm and the swing arm is required to open the supporting arm and the swing arm by using a low rotate dynamic strength to rotate the bar, thus the elevation angle between the supporting arm and the swing arm can be quickly opened or closed, and the rising operation can be faster and smoother with less time. | 06-24-2010 |
20100139429 | ACTUATOR FOR LIFTING DEVICE - An actuator includes a base, a motor mounted on the base for driving a worm to rotate a worm gear of a transmission gear set that is set in an accommodation chamber inside the base and has a gear shaft pivotally inserted through the worm gear and fixedly mounted with an output gear, a brake module rotatable with said worm gear, a linking rod assembly having a driven gear meshed with the output gear, a screw rod rotatable with the driven gear, a movable member threaded onto the screw rod and an extension rod connected to the movable block and movable in and out of a sleeved outside the base upon rotation of the screw rod for biasing a crane beam of a lifting device. | 06-10-2010 |
20090308191 | LIFTING MOTOR DRIVE - A lifting motor drive includes a gearbox housing, a transmission shaft mounted inside the gearbox housing and having a first connector at one side for the connection of an external object to be moved by the transmission shaft and a second connector at the other side for the connection of a crank handle for allowing rotation of the transmission shaft manually by a user, a motor for rotating the transmission shaft through a driving gear and a driven gear, and a thermistor, which detects the working temperature of the motor and cuts off power supply from the motor when the working temperature of the motor surpasses a predetermined temperature level. | 12-17-2009 |
20090293655 | LINEAR ACTUATOR - A linear actuator includes a housing formed of a first half shell and a second half shell and defining an accommodation chamber, a front opening in front of the accommodation chamber and a receiving chamber at the bottom side of the accommodation chamber, a driving mechanism having a push rod movably mounted in the accommodation chamber and extending out of the front opening, a motor mounted outside the accommodation chamber and a spindle coupled to and rotatable by the motor for causing the transmission shaft to reciprocate, and limit switches detachably mounted in the receiving chamber for stopping the motor upon movement of the transmission shaft to a front or rear limit position. | 12-03-2009 |
