A security lock is a type of lock used for tagging and locking in workshops and offices. This is to ensure that the energy of the equipment is absolutely turned off and the equipment remains in a safe state. Lockout prevents accidental activation of the equipment, which could result in injury or death. Another purpose is to serve as a warning, such as fire equipment locks in shopping malls, which are different from the anti-theft function of ordinary locks.

1. The lock should not be exposed to rain for a long time. Falling rainwater contains nitric acid and nitrates, which can corrode locks. 2. Always keep the lock head clean and do not let foreign objects enter the lock core, which may cause difficulty or even failure in unlocking. 3. Regularly inject lubricating oil, graphite powder or pencil powder into the lock core to help reduce the oxide layer left by long-term use. 4. Pay attention to the thermal expansion and contraction caused by the weather (wet in spring and dry in winter), and ensure that the gap between the lock body and the key is properly matched so that the lock can be used smoothly.
