Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, and in particular to an angle adjustment device for a fire box and connecting pipe. Background Technology

[0002] Fire is one of the most common and widespread disasters in human society that seriously endangers public safety. Fire extinguisher boxes are devices that provide fire extinguishing equipment to fire scenes. They are an important fire-fighting measure for buildings, factories, mines, and public places. When using fire extinguisher boxes, it is often necessary to connect connecting pipes to the fire extinguisher box in order to carry out fire extinguishing work.

[0003] Currently, fixed-angle connectors are commonly used in the connection methods between fire extinguisher boxes and pipelines. While simple, this method lacks flexibility. In actual use, the location of the fire extinguisher box and the direction of the pipeline are not always in the ideal orientation. Fixed-angle connections can only extinguish fires in a specific direction and cannot be adjusted according to actual conditions. This makes it difficult to meet the needs of different scenarios, reduces the flexibility of fire protection facilities, leads to difficulties in installation and commissioning, and ultimately affects the effectiveness of fire protection functions.
