Description
technical field [0001] The invention relates to the field of safety pins, in particular to a safety pin for an elevator and a manufacturing method thereof. Background technique [0002] Elevator maintenance personnel must use safety pins for elevators when they overhaul the elevator. Therefore, the excellent reliability of safety pins cannot be ignored by elevator maintenance personnel. On the market, the reliability of most elevator safety pins is questionable. Moreover, most elevator safety pins will inevitably be corroded by the environment after a long period of use, resulting in rust problems, which will affect the reliability of the safety pins. Contents of the invention [0003] In view of the above, the object of the present invention is to provide a safety pin for an elevator and a manufacturing method thereof, so as to solve the problems existing in the prior art. With the advantages of high reliability and excellent corrosion resistance, the present invention ...
