Abstract:
In a power supply module of a linear actuator and a conversion assembly thereof, the power supply module includes a casing (10), a circuit control unit (11), and a conversion assembly (2). The casing (10) is provided with a dividing plate (102) for dividing the interior of the casing (10) into a first space (103) and a second space (104). The circuit control unit (11) is disposed in the first space (103), and the conversion assembly (2) is disposed in the second space (104). The conversion assembly (2) further includes a circuit board set (20) and a frame (21). The circuit board set (20) is electrically connected with an inductive element(A), a rectifying element(B) and a filtering element(C). The circuit board set (20) is mounted onto the frame (21) to form a modular structure.
Abstract:
A foot switch having a security mechanism includes a main body, a circuit board, a pedal and a latch. The circuit board is received in the main body. The pedal is provided on the main body. The latch is provided adjacent to the pedal. The pedal is electrically connected to the circuit board via the latch. When the latch and the pedal are pressed, the circuit board is electrically connected to the pedal. The pedal can only generate an unlocking action via the latch, whereby the circuit board is electrically connected to the pedal to output a driving signal. Thus, the foot switch of the present invention can be prevented from being stepped on by mistake, thereby enhancing the safety in use.
Abstract:
A transmission mechanism having a deceleration function includes a guide screw, a worm wheel set, an intermediary ring, an isolator and a passive sleeve. The worm wheel set is fitted onto the guide screw and includes worm wheel and plural claw arms. A spacing slot is formed between any two adjacent claw arms. The intermediary ring is fitted onto a peripheral edge of each claw arm. The isolator surrounds a peripheral edge of the intermediary ring with one side fixed to an actuator. With plural grooves arranged on a peripheral edge thereof, the passive sleeve is fitted onto the guide screw. An accommodation space is formed among the groove, spacing slot and intermediary ring. Each needle roller is accommodated in the accommodation space and inter-contacted with the claw arm, the intermediary ring and the passive sleeve.
