Abstract

The utility model provides a fire hose connects, it includes the main part and attaches the body, main part one end outside is the interface, interface to interface butt joint squirt or water source, toroidal cavity side along the annular enclosure of welding of another outside of main part department placed in the middle, the outer ring body of annular enclosure is equipped with the screw, it follows to take over inboard the inboard of annular surrounding edge one end that align of following of annular of one end, and by electric welding seal welded, it is the interface to attach body one end, the inboard interior ring body of interface is equipped with the screw, toroidal cavity side along the welding sleeve one end of attaching another outside of the body, area body one end is passed in the sleeve cavity, the outer port of area body one end ring body along the sleeve in passes, and entangle the outer ring body that the main part was directly taken over, the screw that closes on the outer ring body of the annular surrounding edge of main part one end is twisted to the screw that attaches on the interior ring body of body one end.

Description

A kind of fire hose coupling

Technical field

The utility model relates to a kind of water-band joint, particularly relates to a kind of fire hose coupling.

Background technique

The joint of known fire-extinguisher water hose is all that water-band external port is packed on the outer ring body of joint one adapter, then fasten with circle, this set up one be assembling or dismounting pipe racks cumbersome, also need assistant tool compounding practice, the scene of fire is fast changing, sometimes within one minute, just can change whole situation in advance; Two be circle button be exactly an annular iron plate circle in fact, buckle ring often there will be get rusty rot and cause rupture phenomenon.

Someone utilizes anti-skid principle in addition, apply for the patent of invention of " fire hose coupling " (patent No. 201210201890.3), it mainly utilizes the first magnet in upper connection outer ring body draw-in groove and the second magnet on fixed base mutually hold or repel, the cutting ferrule in lower contact is then utilized again to be locked the water-band of corresponding part, it is this that to set up maximum benefit be that water-band and joint are very firm, but its action need instrument coordinates, and water-band and jiont treatment well also need 3 to 4 minutes.Patent about this respect has a lot, and this is a most representative example.

Summary of the invention

In order to overcome existing fire hose coupling deficiency existing in operation, the utility model provides a kind of fire hose coupling, the attached body one headgear cylinder of this water-band joint directly entangles the adapter of main body one, and adapter outer ring body rubber surface meet water then can undergoes rapid expansion, and it is more firm to make water-band be connected with adapter, whole docking operation only needs a few second, and without the need to any assistant tool.

The utility model solves the technological scheme that its technical problem adopts: comprise main body and attached body, main body outside is docking port, the interface at docking port docking hydraulic giant or water source, outside main body other end, the toroidal cavity side of middle part is along the annular enclosure of welding, the outer ring body of annular enclosure is provided with screw thread, the annular inboard that adapter is one is along the edge, inner side of alignment annular surrounding edge one, and by electric welding seal welding, take over as bilayer is set up, adapter is outer is set up by rubber material, adapter internal layer is set up by metallic material, the outer ring body of inner metallic layer embeds in the inner ring body of rubber outer, and it is mutually bonding, the internal cavities of adapter is communicated with the internal cavities of main body, attached body one is interface, the inner ring body of interface inboard is provided with screw, toroidal cavity side outside attached body other end is along welded sleeve one, the internal cavities of sleeve is communicated with the internal cavities of attached body, sleeve is greater than the external port of sleeve other end facing to the external port of adapter one, belt body one is through in sleeve cavity, the external port that belt body is one is passed along sleeve inner ring body, and entangle the outer ring body of main body one adapter, then be, screw on attached body inner ring body screws up the screw thread on main body one head annular surrounding edge outer ring body.

The beneficial effects of the utility model are, the rubber layer one of adapter outer ring body runs into water then can undergoes rapid expansion, and it is more firm to make water-band be connected with adapter, sleeve inner cavity one with take over the external port of docking and be greater than other end external port, be provided with following benefit like this: once being the adapter of main body one of being locked; Two is that the used time is not convenient to pull out.Without any need for assistant tool when originally setting up operation, operator can directly manually be connected, and whole process only needs just can complete a few second.
