Centrifuge with lid closed by safety lock during operation - has torque-dependent limit switch to hold lock until rotor stops

摘要

A centrifuge has a lid automatically locked closed by a locking mechanism when the motor is driving the centrifuge rotor. The support base for the drive motor is directly or indirectly connected to an actuating element for a limit switch. The torque of the motor causes a displacement of the actuating element and causes the limit switch to respond. A simple, reliable and economic mechanism is obtd. for ensuring that the lid can only be opened when the centrifuge is completely stopped.
