Description

Technical Field

[0001] The invention relates to the technical field of fire extinguisher box installation, in particular to a fire extinguisher box hidden door structure and a construction method thereof. Background Art

[0002] In order to consider factors such as the integrity and aesthetics of the decoration when installing the fire extinguisher box, some fire extinguisher boxes, pipe wells, etc. are often decorated with hidden doors during the decoration process of some house buildings.

[0003] The patent document with publication number CN103343656A discloses a fire extinguisher hidden door structure, including a U-shaped rotating shaft transmission device, two fan-shaped three-petal hinge devices and a hyperbolic door guide limit device. The two fan-shaped three-petal hinge devices are respectively installed on both sides of the U-shaped rotating shaft transmission device through rotating shafts to realize eccentric movement of the door and hyperbolic opening. The hyperbolic door guide limit device is two wedge-shaped fixed blocks, one of which is fixed between the fire extinguisher hidden door and the rotating shaft, and stops rotating when it is opened to 180 degrees for the second time; the other hyperbolic door guide limit device is fixed inside the U-shaped rotating shaft transmission device to control the door leaf so as not to collide with the facade finish when it is opened for the first time.
