Calamity,.
With the development of science and technology, there are huge progress, but its work(in fire hose street corner on material and structure
Can too it limit to, it is single, mostly it is connection water band, it is few for the miscellaneous function of fire fighting, it is known that when fighting a fire,
It needs to control hydraulic pressure, to make the water of ejection be fully utilized, and existing fire hose does not have the function of changing hydraulic pressure, this is
We will solve the problems, such as.
Invention content
The present invention provides a kind of mechanical fire hose couplings for ship, by being equipped with circular seal washer, spiral shell
Line pipe and hydraulic pressure test table, it is not close to solve the connection of existing fire hose coupling, the problem of can not changing hydraulic pressure size.
In order to solve the above technical problem, the present invention provides the following technical solutions：
The present invention provides a kind of mechanical fire hose coupling for ship, including the first steel sleeve, the steel sleeve
Bottom connect the first fixing axle, the top end surface of first fixing axle is equipped with bolt, and the bottom of first fixing axle is set
There are circular seal washer, the bottom end of the circular seal washer to be equipped with the second fixing axle, the outer surface of second fixing axle is set
There are hydraulic pressure test table, outside to connect hand crank, connected by screwed pipe between first fixing axle and second fixing axle,
The bottom end of second fixing axle connects the second steel sleeve, the top end surface of the circular seal washer and second fixing axle
It is equipped with tapped through hole.
As a preferred technical solution of the present invention, one end of the hand crank is cased with rubber sleave, and described hand
And second fixing axle welding.
As a preferred technical solution of the present invention, first fixing axle and the screwed pipe are threadedly coupled, described
Second fixing axle and screwed pipe welding.
As a preferred technical solution of the present invention, there are four the bolt and the tapped through hole are respectively provided with, and institute
It states bolt and the tapped through hole is located on same vertical vertical line.
As a preferred technical solution of the present invention, first steel sleeve and the screwed pipe are tapered.
The advantageous effect that is reached of the present invention is：This kind can quickly change the fire hose coupling of hydraulic pressure size, pass through hand
The rotation of crank makes screwed pipe to the first steel sleeve inner rotation, to drive the rotation of the second steel sleeve, thus reduces water spray
The path gone out, to change the size of hydraulic pressure, this method not power consumption, and also it is easy to operate, it, can be very in fire control
Good auxiliary fire-fighting work.

Specific implementation mode
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
Embodiment：As shown in Figs. 1-2, the present invention provides a kind of mechanical fire hose coupling for ship, including
The bottom of one steel sleeve 1, steel sleeve 1 connects the first fixing axle 3, and the top end surface of the first fixing axle 3 is equipped with bolt 2, and first is solid
The bottom of dead axle 3 is equipped with circular seal washer 4, and the bottom end of circular seal washer 4 is equipped with the second fixing axle 6, the second fixing axle 6
Outer surface is equipped with hydraulic pressure test table 7, and outside connects hand crank 10, passes through screwed pipe between the first fixing axle 3 and the second fixing axle 6
The top end surface of 5 connections, the second steel sleeve 8 of bottom end connection of the second fixing axle 6, circular seal washer 4 and the second fixing axle 6 is equal
Make screwed pipe 5 to 1 inner rotation of the first steel sleeve, to drive second by the rotation of hand crank 10 equipped with tapped through hole 9
Steel sleeve 8 rotates, thus reduces the path of water ejection, and to change the size of hydraulic pressure, Korea Spro is not electric for this method, Er Qiecao
Make simply, in fire control, can be good at assisting fire-fighting work.
One end of hand crank 10 is cased with rubber sleave 11, and hand crank 10 and the welding of the second fixing axle 6, increases hand and hand
10 frictional force, facilitate rotation.
First fixing axle 3 and screwed pipe 5 are threadedly coupled, and the second fixing axle 6 and screwed pipe 5 weld, and ensure that screwed pipe 5 is revolving
When rotating into the first steel sleeve 1, the rotation of the second steel sleeve 8 is driven.
There are four bolt 2 and tapped through hole 9 are respectively provided with, and bolt 2 and tapped through hole 9 are located on same vertical vertical line, make
First fixing axle 3 and the second fixing axle 6 connect closer, prevent leak.
First steel sleeve 1 and screwed pipe 5 are tapered, keep the basis of screwed pipe 5 and the first steel sleeve 1 closer, simultaneously
Also it can increase hydraulic pressure.
In the use of the present invention, our rotations by hand crank 10, make screwed pipe 5 to 1 inner rotation of the first steel sleeve,
To drive the rotation of the second steel sleeve 8, thus the path of water ejection is reduced, to change the size of hydraulic pressure, this method
Not Korea Spro's electricity, and it is easy to operate, in fire control, can be good at assisting fire-fighting work, we by the first fixing axle 3,
Second fixing axle 6, screwed pipe 5 and circular seal washer ajust that its is water-tight to connect two water bands, and hydraulic pressure test table 7,
The hydraulic pressure that survey can be added to pass through prevents hydraulic pressure excessive, and water band is made to burst.
This kind can quickly change the fire hose coupling of hydraulic pressure size, by the rotation of hand crank 10, make screwed pipe 5 to
One steel sleeve, 1 inner rotation to drive the rotation of the second steel sleeve 8, thus reduces the path of water ejection, to change water
The size of pressure, this method not power consumption, and also it is easy to operate, in fire control, can be good at assisting fire-fighting work.
Finally it should be noted that：The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention,
