Description
Structural principle
Core components:
Pin body: Mostly cylindrical in shape, materials include carbon steel (45#, 35CrMo), stainless steel (304/316) or aluminum alloy (6061), with surface galvanization or blackening treatment.
Head: Common types include cotter pins, flat heads, round heads or perforated heads (used for threading steel wire for locking).
Tail: The tail of some safety pins is equipped with external threads, open grooves or elastic retaining rings to prevent detachment.
Working principle:
By inserting into the pin holes of mechanical components, the relative movement of the components is restricted to achieve positioning, locking or overload protection.
When the load exceeds the set value, the safety pin can be cut to protect the main structure.
Core advantage
Overload protection: The shear pin acts as a "sacrificial component" to prevent damage to expensive equipment;
Easy installation: The quick-release pins can be disassembled and assembled without tools, increasing maintenance efficiency by 50%.
Low cost: Simple structure, with a single cost of 0.1 to 100 yuan, which is much lower than the maintenance cost of the main equipment.
