定义
A precision-engineered mechanical component designed to physically lock machine guards, doors, or access panels in closed positions as part of safety interlock systems. It prevents unauthorized or accidental opening during machine operation cycles, ensuring operator safety by maintaining isolation from moving parts, electrical hazards, or process areas.
工作原理
Operates through mechanical engagement where a bolt or latch extends into a receiver or strike plate when activated, creating a positive lock. Typically integrated with electrical or pneumatic systems that monitor lock status, preventing machine startup unless fully engaged and allowing release only when safe conditions are met.
材料
High-strength alloy steel (AISI 4140/4340)stainless steel (316/304)or engineered polymers (PEEKreinforced nylon) depending on application requirements. Surface treatments include zinc platingblack oxide coatingor passivation for corrosion resistance.
IP Rating
IP65/IP67
Locking Force
200-5000 N
Response Time
<100 ms
Stroke Length
5-50 mm
Actuation Type
Solenoid, pneumatic, mechanical
Electrical Rating
24V DC, 5A max
Operating Temperature
-20°C to +120°C
标准
ISO 14119ISO 13849-1DIN EN 1088ANSI B11.19

常见问题

What is the primary function of a locking bolt in interlock systems?

To physically prevent access to hazardous machine areas during operation by securing guards or doors, ensuring safety compliance and preventing accidents.

How do locking bolts integrate with machine control systems?

They connect to safety relays or PLCs through position sensors, providing feedback that prevents machine startup unless properly engaged and allows controlled release during safe conditions.

What materials are best for corrosive environments?

Stainless steel (316 grade) with appropriate surface treatments provides optimal corrosion resistance in harsh industrial environments.
