Abstract

The present invention relates to an electric legs-separating mechanism. Said mechanism includes the following portions: motor, worm and worm gear, swing block, leg bars, photoelectric switch, optical signal transmitting contact head, optical signal receiving contact head and programmable controller. Said invention also provides their connection mode and working principle of said legs-separating mechanism.

Description

technical field [0001] The invention relates to an electric leg splitting mechanism, which is usually used to control the opening or closing action of the leg plate of a medical delivery bed. Background technique [0002] The existing electric leg splitting mechanism includes a motor, a worm connected to the output shaft of the motor, a worm wheel meshed with the worm, a pendulum connected to the worm gear, a leg rod fixedly connected to the pendulum, and the legs of the delivery bed. The plate is set on the leg bar, and a mechanical travel switch is set between the power supply and the power input end of the motor, that is, when the pendulum drives the leg bar to move to realize the opening or closing of the leg plate, through the mechanical structure Movement to touch the limit switch to control the working state of the motor. However, since the travel switch is directly touched during the working process, the travel switch will be worn after long-term use, which will eas...
