⚙️ Working Principle
The working principle of bow shaped shackles is mainly based on the principle of elastic deformation of metals. When current passes through a conductive device, the bow shaped plate is subjected to magnetic force and undergoes bow shaped deformation. The rebound force generated by this deformation can counteract the magnetic force of the current, thereby achieving automatic tripping. When the current exceeds the rated current, the bow shaped plate reaches its maximum bending amount, causing the contacts on the fixed rod to instantly separate, thereby achieving rapid power-off and avoiding the harm of free arc and when the current is cut off, the restoring force of the bow shaped plate will cause the contact point to return to the fixed pole position, restoring power supply.
Structural Composition: The bow shaped shackle is mainly composed of bow shaped pieces, fixing rods, limit pieces, and wiring bases. The bow shaped plate undergoes bow shaped deformation when subjected to magnetic force, and the limiting plate ensures the maximum deformation of the bow shaped plate. The fixing rod is used to connect the contacts.
Application Scenarios: Bow shaped shackles are widely used in various AC circuits, such as AC contactors, low-voltage switchgear, circuit breakers, fuses, etc. Its advantages include compact structure, easy installation, stable signal, and good stability performance after heating up. In addition, bow shaped shackles are also commonly used in lifting, towing, and other scenarios, named after their similar shape to bows and arrows.
🌐 Scope of Use
Bow shaped shackles are mainly used for lifting and towing, named after their shape resembling bows and arrows. It is widely used in industries such as power, metallurgy, petroleum, machinery, railway, chemical, port, mining, and construction as a connector. Bow shaped shackles are also commonly used in trailers, which are connected to the trailer position of the car with trailer ropes or lifting straps for easy disassembly to meet different combination requirements.
The design features of bow shaped shackles include a wide space inside the buckle body, suitable for connecting different rigging, and easy disassembly and reassembly. In addition, the middle position of the buckle body of the bow shaped release buckle is designed with a wide space, which is suitable for connecting the ring eye of the white lifting belt, avoiding the problem of compact compression.
⚠️ Safety Notice: When using bow shaped shackles, it is necessary to pay attention to safety inspection and maintenance. Before use, the buckle body and pin should be checked for severe wear, deformation, or fatigue cracks. During use, the axle pin must be securely inserted with a safety pin to ensure that the safety load does not exceed the specified safety load. Regularly conduct visual inspections to promptly identify and address defects that may affect safe use.
