Product core information

This product is a pipe well lock , produced by the brand "QIANG LANG". It is specially designed for pipe well doors (such as fire pipe wells, power distribution wells, power wells and other special areas in buildings). It has both security isolation and access control functions to ensure the safety and normal operation of facilities in the pipe well.

Functional and structural analysis

• Functional Positioning : The core function is to restrict unauthorized personnel from entering the pipe shaft and to achieve regional safety isolation through locks. It belongs to the category of building safety facilities.

• Structural Design : Made of metal (such as stainless steel, zinc alloy, etc.), the lock body, lock tongue and other components are not reinforced for fire resistance, but focus more on security isolation and access control. The lock contains core components such as the lock cylinder, lock tongue, and lock body. The lock cylinder can achieve "one key for all" or "multi-key management". The lock tongue switch has obvious feedback and is easy to install.

Application scenarios and advantages

• ‌Scenario‌ : Widely used in building manholes (fire protection pipe wells, power distribution wells, electrical wells, etc.) to meet the safety protection needs of manhole doors.

• Advantages : Simple structure, easy installation, and permission management achieved through lock core design to ensure the safety of the pipe well area; some products support "one key for all", improving management efficiency.

Difference from fireproof lock

There are significant differences in the functions and structures of manhole locks and fireproof locks: fireproof locks must meet fire protection standards, use high-temperature resistant/non-flammable materials, and undergo fire protection tests; while manhole locks focus on safety isolation, and their structures are not optimized for fire protection performance. The two cannot be confused.
