Preferably, the other end that nipple is connected with fire hose, which is circumferentially provided with stopper slot, stopper slot, is arranged with folder
Hold the reinforcing ring of nipple.
By using above-mentioned technical proposal, reinforcing ring strengthens the intensity of nipple, prevents nipple from being opened because of inside water pressure
Split.
Preferably, nipple is held between A ends inwall and B ends end face.
By using above-mentioned technical proposal, nipple is fixed by the way of clamping, is easy to the installation of nipple.
Preferably, the connection one end at A ends and B ends is extended axially by limited post, limited post radially extends limited location
Block；A ends are provided with the mounting groove for the insertion of other side's limited block with B end wall surfaces, and mounting groove includes what is be axially inserted into for limited block
Part I and limited block circumferentially rotate the Part I with the clamping of B ends so as to A ends.
By using above-mentioned technical proposal, A ends are interfixed with B ends by the way of rotary clamping is needed, and rotary clamping is made
Connected mode is fast and easily detachably fixed for one kind, meets national standard GB3265 requirement.
In summary, the utility model has the advantages that：Water band is connected using nipple, and in extraneous head parcel
While joint is protected, nipple is ensured with taking aim at son/fire hydrant, so as to ensure the unimpeded of water route.
