AI Technical Summary
The closing button is easily touched, leading to accidental closing, and it is also easily damaged in outdoor environments.
A spring-operated mechanism closing interlock device was designed, including a protective mechanism, comprising a mounting base, a slide groove, a slide rod, a sliding block, a spring, and a protective cover. The protective cover is slidable and can be reset by the spring to block the control surface. It is fixed by a rotating connecting rod, a bolt sleeve, and a bolt. The protective cover is made of engineering plastic.
It effectively prevents accidental contact of the closing button, avoids misoperation, protects the button from damage, improves the safety and stability of the device, reduces the risk of equipment damage, and extends its service life.
