Anti-falling fire hose

Abstract

The invention discloses an anti-falling fire hose in the technical field of fire protection. A first connecting block is mounted at the right end of a first water band. A second connecting block is mounted at the left end of a second water band. A bolt is arranged at the right end of the first connecting block. A bolt groove matched with the bolt is formed in the left end of the second connectingblock. A baffle is mounted at the left end of a compression spring. Guide wheels are correspondingly arranged at the upper end and the lower end of the baffle. The inner end of an adjusting rod extends to an inner cavity of the bolt groove. A positioning block is mounted at the inner end of the adjusting rod through a connecting bearing. The device is easy to operate, when in use, a worker insertsthe bolt on the first connecting block into the bolt groove in the second connecting block, so that the compression spring is compressed by force; the positioning block moves into a positioning groove, so that the first connecting block and the second connecting block are effectively prevented from falling off; by rotating a sleeve through a handle, a telescopic rod drives the positioning block to move outwards, and the positioning block is taken out from the positioning groove, so that the baffle pushes the bolt to move to the left, and the splitting efficiency of the first connecting blockand the second connecting block is improved.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to an anti-shedding fire hose. Background technique [0002] In the field of fire fighting, fire hoses are common fire-fighting equipment. During fire-fighting work, according to the location of the fire, the fire hoses need to be spliced ​​and lengthened. In the prior art, the splicing of fire hoses is simply by using buckles. The card slot connection is easy to fall off at the connection due to excessive water pressure in the hose during use, which seriously affects the firefighting work. Therefore, we propose a fire hose that prevents falling off. Contents of the invention [0003] The object of the present invention is to provide an anti-falling fire hose to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a fire hose that prevents fa...
