Embodiment 1

[0027] Present embodiment 1 proposes a kind of fire hose auxiliary mechanism, such as figure 1 , figure 2 as well as image 3 As shown, it includes a body 1, which is an annular body formed by butting two identical semi-annular first hoops 101 and second hoops 102. The inner radial surface of the body has two parallel annular grooves, wherein One annular groove is a female groove 1011 for matching the female end of the hose interface, and the other annular groove is a male groove 1021 for matching the male end of the hose interface. One of the first ferrule and the second ferrule One set of opposite connecting ends are joined by hinges 301, the other set of opposite connecting ends are joined by a locking device, the locking device includes a locking bar 401 and a spring latch 402, and the connecting end of the first hoop is set toward the second The cylindrical locking bar of the hoop, the locking bar is provided with a pin hole 403 perpendicular to its axis, the connectin...

Embodiment 2

[0029] This embodiment 2 proposes a fire hose auxiliary mechanism. This embodiment 2 is basically the same as the above-mentioned embodiment 1, the difference lies in the guiding device on the body, such as Figure 4 As shown, a plurality of evenly distributed one-way wheels 6 are arranged on the radially outer surface of the body 2, the wheel frame of each one-way wheel is connected with the body, and the axis of each one-way wheel is perpendicular to the axis of the body.

Embodiment 3

[0031] This embodiment 3 proposes a fire hose auxiliary mechanism, this embodiment 3 is basically the same as the above embodiment 1, the difference lies in the guiding device on the body, such as Figure 5 As shown, a number of evenly distributed universal balls 7 are arranged on the outer radial surface of the body 3, and the support plates of each universal ball are connected to the body.

Abstract

The invention relates to an auxiliary mechanism of a fire hose. A body is an annular body formed in a way that a first bracelet and a second bracelet which are the same and are semicircular are butted, two parallel annular grooves are formed in the inner radial surface of the body, one annular groove is a mother groove and is matched with the mother end of a hose connection, the other annular groove is a male groove and is matched with the male end of the hose connection, and two butt parts of the first bracelet and the second bracelet are connected so as to fixedly clamp the male end and themother end of the hose. Compared with the prior art, the auxiliary mechanism has the advantages that the mother connection and the male connection of the hose are prevented from being separated and falling during pulling, and the service life of the hose connections is prolonged.

Description

technical field [0001] The invention relates to a fire fighting equipment, in particular to an auxiliary mechanism for a fire hose. Background technique [0002] The fire hose is a pipeline used to transport flame-retardant liquids such as high-pressure water or foam. At present, in the process of fire fighting and rescue, the fire hose is a very high-use equipment. In the actual application process, especially after an underground fire , the fire officers and soldiers need to drag the hose that has been filled with water into the underground to put out the fire. There are many curved sections and corners in the underground. The interface falls off, and it is difficult to lift, which consumes a lot of physical strength of firefighters and soldiers, and will delay the best time to put out the fire. Contents of the invention [0003] The purpose of the present invention is to provide a fire hose auxiliary mechanism to solve the technical problems that the hose interface is ...
