Blocking type high-pressure water hose fire-fighting interface with 360-degree rotary hook ring

Abstract

The invention discloses a blocking type high-pressure water hose fire-fighting interface with a 360-degree rotary hook ring. The blocking type high-pressure water hose fire-fighting interface comprises a fire-fighting interface body which is connected with a fire-fighting water hose and the rotary hook ring which is connected with a suspension part for applying pulling force to the fire-fighting interface body, wherein the rotary hook ring is sleeved on the fire-fighting interface body and can rotate by 360 degrees relative to the fire-fighting interface body. According to the blocking type high-pressure water hose fire-fighting interface with the 360-degree hook ring disclosed by the invention, the rotary hook ring is connected with the suspension part to provide pulling force for the fire-fighting interface body and the fire-fighting water hose; and rotation of the fire-fighting interface body is not limited, so that use convenience is improved, and safe and reliable water supply isensured.

Description

technical field [0001] The present invention relates to fire fighting equipment, in particular, the present invention relates to a cassette-type high-pressure hose fire interface with a 360° rotating shackle. Background technique [0002] At present, the fire-fighting interface of the cassette hose used by the domestic fire brigade is manufactured in accordance with the standard of GB12514-2005 "Fire Interface". Aluminum alloys and other cast or pressed aluminum alloys not less than their properties. The performance of the existing cassette hose fire interface can no longer meet the requirements of high-rise and super-high-rise fire fighting operations. The reason is that in high-rise and super high-rise fire fighting and rescue operations, the method of laying fire hose is: vertical laying outside the wall and along the stairs. Lay two. In the former method, due to the water pressure in the hose and the water in the hose and the weight of the water in the hose, the fire i...

The performance of the existing cassette hose fire-fighting interface can no longer meet the requirements of high-rise and super-high-rise fire-fighting operations. lay two

In the former method, due to the water pressure in the hose and the water hose and the weight of the water in the hose pipeline, the pressure on the fire protection interface is too heavy, especially the pressure on the uppermost hose is too heavy, and the hose often needs to be supported by a hanger to reduce the pressure. The pressure burden of the fire-fighting interface, so the weight of carrying hoses and other fire-fighting and rescue equipment in fire-fighting and rescue has exceeded the limit of the firefighters’ load-bearing. The weight of the hose hanger has restricted the burden of firefighters, and the hose hanger also needs Installation at a fixed support is both laborious and affects the rapid fire extinguishing time; if the latter method is adopted, laying the hose along the stairs will easily cause the hose to bend and affect the water supply
