The fire-fighting clamping mechanism of the utility model embodiment is described in detail with reference to the accompanying drawings.
As shown in Figure 1, according to the fire-fighting clamping mechanism of the utility model embodiment, including pipe fitting 10, attaching nut 20,
Filter 30 and fire nozzle 40.
The pipe fitting 10 includes an installation port 12 and at least one connecting pin for being used to connect with fire extinguisher canvas hose
Mouth 11, the installation port 12 is connected to the connectivity port 11, and is provided with the first internal screw thread in the installation port 12
121。
The upper end outer surface of the attaching nut 20 is provided with the first external screw thread being adapted to first internal screw thread 121
21, the attaching nut 20 is by the cooperation screw engagement of first internal screw thread 121 and the first external screw thread 21 in the installation
In port 12, and it is perforative above and below the center of attaching nut 20 be provided with a through-hole 22, the upper end of the through-hole 22 is provided with
Two internal screw threads 23, lower end are provided with third internal screw thread 24.
The filter 30 can be extend into the pipe fitting 10 from the installation port 12, and the connection of its lower thread
It is mounted in second internal screw thread 23.
The threaded connection of the fire nozzle 40 is mounted in the third internal screw thread 24 of the attaching nut 20.
Preferably, the pipe fitting 10 includes that there are two the connectivity port 11, two companies as one embodiment
The central axis for connecing port 11 is on same straight line, the central axis of the installation port 12 and two connectivity ports 11
It is mutually perpendicular to, forms three-way pipe structure.Also water is said, the horizontal left and right ends of the pipe fitting 10 are respectively interconnected connection
Port 11, and it is respectively provided with the internal screw thread that installation is adapted to fire extinguisher canvas hose, and port 12 is installed downwards, and connect with two
Channel between port 11 is interconnected.
According to the fire-fighting clamping mechanism of the utility model embodiment, structure is simple, easy for installation, by leading to pipe fitting 10
Cross connectivity port 11 sealing be connected on fire extinguisher canvas hose, 30 lower thread of filter is first connected to attaching nut 20 at this time and is led to
The upper end in hole 22, then the threaded upper ends of attaching nut 20 are connected at the installation port 12 of pipe fitting 10, so that screw thread is installed
It extend into pipe fitting 10 and is fixed in the filter 30 on attaching nut 20, be finally again threadably mounted at fire nozzle 40
The lower end of 20 through-hole 22 of attaching nut.That is, the water in fire extinguisher canvas hose is first after entering from the connectivity port of pipe fitting 10 11
Through-hole 22 after the filtering of filter 30 again by attaching nut 20 is connected to fire nozzle 40, in this way, passing through filter
Scale, anvil cinder and other impurities in the presence of the water of the avoidable fire extinguisher canvas hose of 30 effect or pipe fitting 10 enter fire-fighting
A possibility that causing fire nozzle 40 to block in nozzle 40, but also the body that fire nozzle 40 sprays impurity fragment can be reduced
Product, to help to reduce a possibility that damaging personnel.
It should be noted that existing nozzle arrangements can be used in the fire nozzle 40 in the utility model embodiment, and
The structure for using above-mentioned pipe fitting 10 to cooperate with attaching nut 20 can arbitrarily with change the filter 30 of different form or size with
And fire nozzle 40, it mounts and dismounts all very convenient.
Preferably as one embodiment, as shown in Fig. 2, the filter 30 is the tubulose of upper end closure, lower ending opening
Structure is evenly distributed with several filter hole 31 on outer wall, and the lower end of the filter 30 has and second internal screw thread 23
Second external screw thread 32 of adaptation.The diameter of filter 30 is less than the internal diameter that pipe fitting 10 installs port 12, and length is less than installation end
The distance between inside mouth 12 to 10 upper end of pipe fitting；In this way, filter 30 can the company of being threaded over by the second external screw thread 32
In second internal screw thread 23 of connected nut 20, when the threaded upper ends of attaching nut 20 are bonded in installation port 12, filter 30
Be fixed on inside pipe fitting 10 by attaching nut 20, so as to using several filter hole 31 on its outer wall come to the water in water
Dirt, anvil cinder and other impurities are screened, and the biggish impurity of volume is avoided to enter by the through-hole 22 of attaching nut 20
It results in blockage in fire nozzle 40 to fire nozzle 40.
Preferably as one embodiment, as shown in figure 3, the fire nozzle 40 of the present embodiment includes being mounted on the company
Connector 41 on connected nut 20, the diffuser 42 immediately below the connector 41, the connection connector 41 and diffusion
The linking arm 43 of device 42, the connector 41 have the third external screw thread 411 being adapted to the third internal screw thread 24, the connection
First 41 center offers perforative apopore 412 up and down, and the apopore 412 is opposite with the diffuser 42.
Further, the diffuser 42 includes the shunting body 421 and multiple diffusion teeth 422 of tapered structure, described
The bottom edge for being fixed on the shunting body 421 of multiple diffusion 422 even circumferential of tooth distributions, the tip of the shunting body 421
On the central axis of the apopore 412.
That is, when 40 spray water of fire nozzle, after water enters pipe fitting 10 from fire extinguisher canvas hose, by filter 30
Filtering enter in the apopore 412 of connector 41, and sprayed from apopore 412 to diffuser 42, by diffusion
That disperses after the diffusion of device 42 sprinkle water.
Preferably as one embodiment, the diameter of second internal screw thread 23 is greater than the straight of the third internal screw thread 24
Diameter.That is, the internal diameter of filter 30 is greater than the outer diameter of 40 connector 41 of fire nozzle, it is also just naturally larger than fire nozzle 40
The diameter of apopore 412, in this way, make the inner cavity of filter 30 and outer wall area bigger, the number of filter hole 31 that can be arranged
Amount is more, and water flow can be made more smoothly to enter in the water outlet of fire nozzle 40 after the filtering of filter 30, make fire-fighting
The water flow that nozzle 40 is sprayed is more uniformly smooth.
