C3-1639 Railway Compression Lock
This is a state-visualization compression lock specifically designed for railway vehicles and high-vibration industrial equipment. The product features a spring-return lock cylinder structure, with a prominent red elastomer O-ring positioned at the lock cylinder. When the lock is in an unlocked or not fully locked state, the lock cylinder is pushed outward by the internal spring, causing the red O-ring to be exposed, creating a clear visual warning. Once the lock is correctly secured, the lock cylinder retracts, concealing the red indicator ring, thereby assisting maintenance personnel in quickly identifying the locking status of the equipment door panel. This mechanical state indication design is particularly suitable for equipment cabinets and maintenance doors in railway vehicles, where frequent maintenance, complex equipment distribution, and rapid inspections are required.

What is the function of red and green markings?
It allows maintenance personnel to directly identify the locking status from the front of the lock. Under normal design, green indicates that the lock is fully closed and compressed, while red indicates that it is open or not fully secured, thereby reducing the risk of missing unlocked panels during inspections.
What is the function of the red O-ring?
The red O-ring primarily serves as a mechanical visual status indicator. When the lock cylinder is not fully locked and protrudes outward, the red area is exposed, alerting maintenance personnel to check the locking status.
Can other railway tool lock cylinders be replaced?
Yes. It can be configured with square, triangular, double-tooth, or other railway-specific tool drive forms according to project requirements, to meet the access management needs of different operators, vehicle manufacturers, and maintenance systems.
What data is required from customers during the selection process?
It is recommended to provide the door thickness, the locking distance from the door panel to the door frame, the direction of the lock tongue, the length of the lock tongue, the required compression stroke, the unlocking direction, the specifications of the tool lock cylinder, as well as the IP, vibration, and corrosion resistance requirements.
