Technical Field

[0001] This utility model belongs to the field of fire hose technology, specifically relating to a fire hose for firefighting. Background Technology

[0002] Fire hoses are water jetting tools used for extinguishing fires. When connected to a fire hose, they spray a dense and powerful stream of water, which has advantages such as long range and large water volume. They can be divided into straight stream hoses, spray hoses, and multi-purpose hoses according to different jet forms and characteristics. Among them, the most commonly used hoses are straight stream hoses and spray hoses.

[0003] The existing technology has the following problems:

[0004] 1. Currently available fire hoses on the market are not convenient for users to install and limit the connection of their output pipes, requiring users to spend a considerable amount of time on their use and installation.

[0005] 2. Currently available fire hoses on the market do not have adequate functionality when users need to use them for limiting and clamping spraying. Utility Model Content

[0010] This utility model further illustrates that a limiting flange is fixedly connected to the bottom surface of the main handle, and the limiting flange is connected between the main handle and the fire hose body.

[0011] Using the above technical solution, the limiting flange that connects the main handle and the fire hose body facilitates the user's connection between the fire hose body and the main handle.

[0012] The present invention further explains that a limiting opening is provided through the upper surface of the limiting flange, and the limiting opening is provided around the limiting flange as the center point.

[0013] The above technical solution allows for easy installation of the limiting flange by the user using bolts, with the limiting opening centered around the limiting flange.

[0014] This utility model further illustrates that the inner ring surface of the nut is limited by a threaded rod, and the threaded rod is connected between the nut, the fixing block, and the snap-fit ​​collar.

[0015] Using the above technical solution, the threaded rod connected by the nut, the fixing block, and the snap-fit ​​collar makes it easy for the user to connect the threaded rod and the snap-fit ​​collar.

[0016] This utility model further illustrates that the fixing block connects the nut and the snap-fit ​​collar, and the fixing block is symmetrically arranged with the vertical center line of the nut as the axis of symmetry.

[0017] Using the above technical solution, the fixing blocks symmetrically arranged with the vertical center line of the nut as the axis of symmetry can facilitate the user to stably install the nut onto the snap ring.

[0018] The present invention further explains that a nozzle is fixedly connected to the front surface of the output pipe, and the nozzle is connected to the fire hose body through the output pipe.

[0019] By adopting the above technical solution, the nozzle connected between the output pipe and the fire hose body can facilitate the user to connect the fire hose body and the nozzle.

[0020] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0021] This utility model provides a fire hose for firefighting. Through the coordinated use of the fire hose body, output pipe, nozzle, support rod, anti-slip handle, snap-fit ​​collar, nut, threaded rod, fixing block, main handle, limiting flange, limiting opening, and support handle, the fire hose can be easily installed and used by the user. When the user needs to install the hose, the user inserts the hose into the snap-fit ​​collar, then tightens the threaded rod onto the nut, thus clamping the hose onto the snap-fit ​​collar. This allows the user to snap-fit ​​and install the fire hose, meeting the user's needs for easy installation.
