Opto-electric sensing cover plate structure

Abstract

The utility model relates to electronic technical field discloses photoelectricity response formula apron structure, including escalator bed cover frame, apron, the inside wall of left and right sides of escalator bed cover frame is connected with the rotating lever through bearing rotation, the lateral surface outer wall of rotating lever is fixedly connected with apron, be provided with adjusting mechanism on the escalator bed cover frame, be provided with auxiliary mechanism on adjusting mechanism, adjusting mechanism includes mounting bracket, the front side inside wall of mounting bracket is fixedly connected in the escalator bed cover frame, the top inside wall of mounting bracket is fixedly connected with photoelectricity response switch, in the utility model, through the linkage design of photoelectricity response switch and regulating valve, stop plate, realize apron opening and closing and the intelligent interlock of electric escalator operating state, when needing to open apron, close photoelectricity response switch trigger signal transmission, make stop plate contract and remove the locking of apron, simultaneously automatic cut off electric escalator loop, avoid the escalator misoperation when apron opening.
