Description
Technical field
The utility model relates to a kind of connector of fire hose, specifically a kind of super-pressure fire hose connection knot
Structure.
Background technique
Currently, well known fire coupling, pipe fitting is smooth using outer circle, and port slightly has the ring-type of protrusion, accordingly
The method of the fixation water band of use is: first is that iron wire tying is directlyed adopt, it is not only time-consuming, and but also must have iron wire and vice at hand
Equal tools；Second is that using the flat hoop with nut tension device, this method seems convenient, but in actual use due to high hydraulic pressure and
It frequently results in water band to fall off from flat hoop, the tool that must reuse screws, and delays the opportunity that calamity is robbed in fire-fighting, causes unnecessary wealth
Produce loss.
Utility model content
The purpose of this utility model is in view of the above shortcomings of the prior art, to provide a kind of super-pressure fire hose connection
Structure.
The technical solution of the utility model is as follows:
A kind of super-pressure fire hose connection structure, characterized in that including connector one, connector two, internal layer copper sheathing one, outer
Layer copper sheathing one, internal layer copper sheathing two, outer layer copper sheathing two, attachment cap, the connector one is placed in the outer layer of fire hose one end, described outer
Layer copper sheathing one is placed in the internal layer of fire hose one end, and the internal layer copper sheathing one is placed in the inside of outer layer copper sheathing one, the connector two
It is placed in the outer layer of the fire hose other end, the outer layer copper sheathing two is placed in the internal layer of the fire hose other end, the internal layer copper sheathing
Two are placed in the inside of outer layer copper sheathing two；The internal layer copper sheathing one, outer layer copper sheathing one are matched for clamping tightly jointly with connector one and are fixedly connected
In one end of fire hose, the internal layer copper sheathing two, outer layer copper sheathing two and connector two are matched for clamping tightly jointly is fixedly connected on fire-fighting
The other end of water band, one end of the attachment cap are movably connected on the end of connector one, the other end and two spiral shell of connector of attachment cap
Line connection.
Fire hose braiding layer, the outer layer copper sheathing two, internal layer copper are equipped between the outer layer copper sheathing one, internal layer copper sheathing one
Fire hose braiding layer also is provided between set two.
The side wall of the outer layer copper sheathing one is circumferentially with several outwardly protruding pits, and the side wall of internal layer copper sheathing one is circumferentially set
Have several outwardly protruding pits, internal layer copper sheathing one, outer layer copper sheathing one pit be staggered；Equally, the outer layer copper sheathing two
Side wall be circumferentially with several outwardly protruding pits, the side wall of internal layer copper sheathing two is circumferentially with several outwardly protruding pits,
Internal layer copper sheathing two, outer layer copper sheathing two pit be staggered.
The lateral wall end of the connector one is circumferentially with annular protrusion A, the attachment cap in the junction with connector one,
Its inner sidewall is circumferentially with annular protrusion B, and the attachment cap, connector one are mutually clamped company by annular protrusion A, annular protrusion B
It connects and can relatively rotate.
When the utility model is used, outer layer copper sheathing one and connector one are cooperated, using expansion tool, by outer layer copper sheathing one
It is fixedly clamped with connector one in one end of fire hose；Then inside copper sheathing one is placed in the inside of outer layer copper sheathing one again, the two it
Between accompany fire hose braiding layer, prevent from skidding between two layers of copper sheathing, using expansion tool by internal layer copper sheathing one and outer layer copper sheathing
It is fixed between one.Equally, connector two, outer layer copper sheathing two, the way of internal layer copper sheathing two are as above.The setting of one layer of copper sheathing can not adapt to
Superelevation pressure in water band is unfavorable for expansion tool for it between connector if only merely thickening the thickness of copper sheathing in this way
It is fixed.Therefore, the utility model is especially provided with two layers of copper sheathing, and outwardly protruding pit is arranged on every layer of copper sheathing, and two layers
The setting of pit interlaced arrangement between copper sheathing, pit can reinforce the fastness connected between copper sheathing, between copper sheathing and connector.
The utility model is simple and reasonable, manufactures and is easy, is connected firmly between each component, can meet fire hose
The demand of super-pressure is of great significance to the connection of fire hose, has a vast market space.
