AI Technical Summary
Existing revolving door devices are unable to fully prevent injuries from being trapped and equipment damage under abnormal torque or overtravel conditions. They also lack intelligent control and fault response capabilities, and cannot achieve multiple safety protections.
A torque overload protection mechanism and a circumferential buffer structure were designed. The torque overload protection mechanism automatically slips and disengages when there is abnormal torque. The circumferential buffer structure achieves flexible buffering and return functions through the upper transmission plate and buffer spring, ensuring that the door is tightly closed.
It effectively prevents people from getting trapped, improves equipment safety and reliability, maintains the airtightness of the door, and extends its service life.
