An indoor fire hydrant

Abstract

The invention relates to an indoor fire hydrant and relates to the field of fire-fighting equipment in buildings. The problems that a fire hydrant door is inconvenient to open and occupies a large space after being opened are solved. The indoor fire hydrant comprises a box body and the fire hydrant door arranged on the box body, the fire hydrant door is arranged on the box body in a slippage manner in the vertical direction, the bottom of the box body is provided with a bearing plate for bearing the fire hydrant door, and the bearing plate is arranged at the bottom of the fire hydrant door ina slippage manner in the horizontal direction. The fire hydrant door is made to slide downwards under the gravity action through the bearing plate performing slippage in the horizontal direction, in the opening process of the fire hydrant door, a user does not need to move according to rotation of the fire hydrant door, the opened fire hydrant door is consistent with the surface of the box body, and it can be avoided that a rescue channel is blocked due to shaking of the fire hydrant door.

Description

technical field [0001] The invention relates to the field of fire-fighting facilities in buildings, in particular to an indoor fire hydrant. Background technique [0002] The indoor fire hydrant is a fixed fire-fighting facility that supplies water to the fire site through the indoor pipe network. In the existing national regulations, there are clear regulations on the installation of fire hydrants, such as the provisions in 5.13.3 of "Fire Hydrant Box" GB14561-2003: The opening angle of the box door shall not be less than 160°. And 5.13.4 stipulates: the opening of the box door should be light and flexible, without jamming, and the opening pull force should not be greater than 50N. Therefore, under normal circumstances, the indoor fire hydrant is fixed by a spring lock, which ensures easy access, but the internal items are easily stolen, resulting in no fire extinguisher being used in case of fire, which delays the rescue time. [0003] And the authorized announcement num...

AI Technical Summary

Problems solved by technology

[0004] The above technical solution discloses an anti-theft type automatic door-opening indoor fire hydrant box. When there is no emergency, only the staff can open the door by swiping the card or entering the password. In case of danger, the access control system loses the fire hydrant The fire hydrant door is automatically opened through the normally open hinge spring. However, the fire hydrant door connected by the normally open hinge spring cannot be close to the wall after opening, so it occupies a certain space and is prone to collision when evacuating in distress. , or block the passage. At the same time, the door body that automatically bounces open in distress is prone to collision accidents at the moment of bounce, and there is a certain safety risk.
