Abstract:
A steering device for use in solar tracking equipment includes: a fixed base (10); a rotary base (20) correspondingly connected to the fixed base (10) and provided with a worm gear (22); and a driving module (30) disposed in the fixed base (10) and including a worm unit (33) and an adjustment mechanism (34), the worm unit (33) includes a cylindrical body (331) and a worm (332) supported in the cylindrical body (331), and the cylindrical body (331) is pivoted in the fixed base (10), the adjustment mechanism (34) is disposed corresponding to the cylindrical body (331) for adjusting the swinging motion of the cylindrical body (331), thereby enabling the worm (332) and the worm gear (22) to be mutually engaged. Accordingly, the backlash between the worm and the worm gear is able to be adjusted thereby enhancing the rotation precision.
Abstract:
An actuator with multi-stage gears includes a worm gear shaft driving assembly having a worm gear shaft, an electric motor having a transmission shaft, an annulus gear arranged between the worm gear shaft and the transmission shaft, and a plurality of multi-stage gears. The annulus gear includes an inner gear and a moving end actuated cooperatively with the inner gear on two ends thereof. The moving end is connected to and driving the worm gear shaft to rotate; each multi-stage gear is arranged between the transmission shaft and the inner gear; each multi-stage gear includes a first and a second outer diameter portions. The outer circumferential edges of the first and second outer diameter portions includes a helical gear engaged with the transmission shaft and a spur gear engaged with the inner gear respectively. Therefore, the actuator has merits of simplified components and reduced volume.
Abstract:
A collapsible power-driven table stand includes a supporting body of an elongated shape, a first stand having a first driving member and a plurality of first extendable rods driven by the first driving member to move axially relative to each other and a second stand having a second driving member and a plurality of second extendable rods driven by the second driving member to move axially relative to each other. The first diving member is pivotally attached to one end of the supporting body and the second diving member is also pivotally attached to another end of the supporting body in order to allow both the first and second stands to extend/collapse relative to the supporting body. Accordingly, the assembly of the collapsible power-driven table is simplified and the overall size thereof is reduced.
Abstract:
In a linear actuator, a limit switch includes an insulation housing formed with an opening and plural slots; a press block disposed on the insulation housing and exposed outside the opening; a pair of connection pins disposed in the insulation housing and spaced with an interval, and respectively protruded from the slots; an elastic connection guiding set including an elastic unit pressed by the press block and a connection guiding sheet connected to the elastic unit, wherein the connection guiding sheet are connected to the pair of connection pins; and a diode disposed in the insulation housing and including two guide pins, wherein the two guide pins are respectively and correspondingly connected to the pair of connection pins in the insulation housing. Accordingly, the electrical connection for the limit switch is simplified thereby facilitating automatic production.
Abstract:
A power-saving remote control apparatus (40) includes a remote control receiving unit (1022) and a main control unit (104). The main control unit (104) is configured to control the power-saving remote control apparatus (40) to enter a working mode when a controlled apparatus (30) needs to be turned on. The main control unit (104) is configured to control the power-saving remote control apparatus (40) to enter a sleeping-power-saving mode when the controlled apparatus (30) stops working, and then for every first predetermined time, the main control unit (104) is turned on to wake up the remote control receiving unit (1022) to scan a plurality of wireless signals (52). The main control unit (104) is configured to control the power-saving remote control apparatus (40) to enter the working mode if the wireless signals (52) include a wireless starting signal (54) for starting the controlled apparatus (30).
Abstract:
A linear actuator includes a housing, a motor, a decelerator and an actuating rod. The housing includes an outer sleeve, a motor sleeve, a connecting sleeve, and at least a motor bolt. The connecting sleeve is connected to one end of the outer sleeve, the motor bolt longitudinally penetrating the motor sleeve and connected to the connecting sleeve. The motor is arranged in the motor sleeve. The decelerator is arranged in the motor sleeve. The decelerator is connected to the motor. The actuating rod is arranged in the outer sleeve. The actuating rod is connected to the decelerator through the motor sleeve, and the actuating rod is driven by the motor through the decelerator. The elements of the linear actuator are thereby firmly assembled by simple structure.
Abstract:
An electrical cylinder controller with a rotational mechanism includes a box, a pivotal element, a fixing element, and a damping member; one end of the box has a hollow tube, the hollow tube internally has a restricting block; the pivotal element penetrates through the hollow tube, the pivotal element has a pivotal-connecting section and a protruding section elongating from the pivotal-connecting section, the external portion of the protruding section has a stopping block against the restricting block; the fixing element connects to the end portion of the protruding section; and the damping member female-connects to the external portion of the protruding section and is clamped between the hollow tube and the fixing element. Therefore, the effect of applying a force to the box for rotation is achieved.
