Description
Technical field
The invention belongs to transfusion tube joint technical field, be specifically related to a kind of hose connection device.
Background technique
At present, domestic for the bigbore hose coupling for delivery of liquid, between its fittings body and flexible pipe, by clip, realize the sealing between joint and flexible pipe, fittings body and connecting body are merged into part of fittings body, this connecting means is simple, convenient, for conveying high-pressure liquid, one end of joint adopts two pairs of clips to be connected (as shown in Figure 8) with flexible pipe conventionally, prevents leak of liquid and the fracture of reply clip.But adopt the method cost high, product weight is heavier, and because fittings body and connecting body are merged into after part of fittings body, and fittings body is connected with flexible pipe and bears highly pressurised liquid rear hose and cannot rotate, clip and fittings body are easily departed from, cause leak of liquid.
Summary of the invention
The object of the invention is to for the above-mentioned deficiency of present technology and provide a kind of simple in structure, install and remove easy to operate, reliable operation, withstand voltage higher, can effectively protect the hose connection device of hose clamp.
The present invention includes two structure fittings bodies identical, that coordinate with flexible pipe; The side of each fittings body is equipped with seal ring, and wall is all set with connecting body, buffering ring outward and for buffering ring and flexible pipe are pressed in to the clip on fittings body; Described connecting body and fittings body are fixed through jump ring;
Each connecting body excircle is provided with a plurality of connection pawls that stretch out;
The corresponding setting of connection pawl on two connecting bodys, forms many groups for connecting the connection buckle of two connecting bodys;
Also comprise that one for preventing the connected rear locking contiguous block that buckle is thrown off that connects of connecting body on two fittings bodies.
On described fittings body outer side surface, the position corresponding with clip is provided with convex tendon.
Described buffering ring cylindrical is provided with protruding lifting eye.
The position corresponding with clip, described buffering ring end is provided with circular arc muscle, on clip, is provided with arc groove with buffering ring joint.
Described buffering ring endoporus is taper hole.
Described locking contiguous block is installed in two groups and connects between buckle, and locking contiguous block is fixed on and connects on pawl through screw.
Described fittings body side excircle is provided with convex edge; Described connecting body inner circumference is provided with for coordinate the boss of assembling with convex edge; On fittings body excircle, be equipped with for boss being pressed in to the jump ring of convex edge.
Described connection pawl is uniformly distributed on connecting body excircle.
Described clip is identical by three valve structures, the circular arc clip of one-step casting moulding, by screw, nut, is interconnected and is formed.
Adopt a kind of devices of protecting hose clamp of formation such as clip, buffering ring, fittings body, connecting body, simple in structure, install and remove easy to operate.During assembling, fittings body coordinates with connecting body endoporus boss, and fixes with jump ring, and fittings body can rotate freely in connecting body.Prevent that flexible pipe from bearing highly pressurised liquid rear hose and cannot rotate, guaranteed the reliability that clip is connected with fittings body.Flexible pipe penetrates buffering ring endoporus, fittings body one end packs in the endoporus of flexible pipe, by three lobe hoop sleeves on hose outside diameter cylindrical body, then will be enclosed within buffering ring on flexible pipe and move to three lobe clip places of prepackage, the circular arc muscle of buffering ring projection is packed in clip arc groove, thereby then fastening clamp screwing is fixed on flexible pipe on fittings body by clip.Thereby while using, only the connection pawl of connecting body need be extend in the connection pawl of another connecting body, and the body that is rotatably connected, make to connect the innermost end of pawl in connecting groove, so just, seal ring that can pressed joint end of body, realize the sealing of end face between fittings body, and can bear higher pressure, finally realize being connected between flexible pipe and flexible pipe.Loosening for preventing connecting body, in the outboard end that connects pawl, be provided with locking contiguous block.During dismounting, only need can make to connect pawl and exit in connecting groove by the opposite direction body that is rotatably connected, make between connecting body separated.Buffering ring cylindrical is provided with protruding lifting eye, at infusion tube, by special region (as seawater, river, valley etc.) time, hawser is hung in lifting eye, can joint and infusion tube is unsettled, guarantee the conveying of liquid.Owing to adopting fixedly flexible pipe of clip, and adopt buffering ring and clip connected, therefore when flexible pipe bears highly pressurised liquid, flexible pipe expands, and first high pressure is delivered to buffering ring inner hole wall, by buffering ring again indirect transfer to clip, the power that clip carries is reduced greatly, avoided clip to rupture.Through verification experimental verification: one end of hose coupling adopts 1 pair of clip and buffering ring to be connected with flexible pipe, when bearing highly pressurised liquid >=6MPa, between flexible pipe and hose coupling, be connected and seal reliably, there is not phenomenon of rupture in clip.
The present invention compared with prior art has dress, it is easy to operate to tear open, reliable operation, and withstand voltage high feature, the conveying mainly for delivery of oils (gasoline, kerosene, diesel oil, machine oil etc.), also can be used for carrying water.

Embodiment
In Fig. 1, Fig. 2, the end of fittings body 7 is provided with seal ring 5, outer connecting body 6 and clip 3 and the buffering ring 2 of being set with of fittings body 7.Fittings body 7 coordinates with connecting body 6 endoporus boss, and fixing with jump ring 4, and fittings body 7 can rotate freely connecting body 6 is interior.Flexible pipe 1 penetrates buffering ring 2 endoporus, fittings body 7 one end pack in the endoporus of flexible pipe 1, three lobe clips 3 are enclosed within on flexible pipe 1 external diameter cylindrical body, the circular arc muscle of buffering ring 2 projections is packed in the arc groove of clip 3, and then on fastening clamp 3, hexagon socket head cap screw 8 and nut 9 are fixed on flexible pipe 1 on fittings body 7.Thereby while using, only the connection pawl of connecting body 6 need be extend in the connection pawl of another connecting body 6, and the body 6 that is rotatably connected, makes to connect the innermost end of pawl in connecting groove, seal ring 5 that so just can pressed joint body 7 ends, realizes the sealing of 7 end faces of fittings body.For preventing that the connected rear locking contiguous block 10 that connects pawl disengagement of connecting body 6 on two fittings bodies 7 is installed between two connection pawls, locking contiguous block 10 is fixed on and connects on pawl through screw 11.
In Fig. 3,7 is fittings body.
In Fig. 4, connecting body 6 outsides are provided with the connection pawl 15 stretching out.
In Fig. 5,4 is jump ring.
In Fig. 6, buffering ring 2 ends are provided with protruding circular arc muscle 12, and buffering ring 2 cylindricals are provided with protruding lifting eye 13.
In Fig. 7, clip 3 is provided with arc groove 14.Three lobe clips link together flexible pipe and fittings body by socket cap hexagon socket head cap screw and nut.
Fig. 8 is the structural representation of the former heavy caliber joint of prior art (one end adopts two pairs of clips).
Working principle of the present invention: when hose coupling does not have pressure-bearing, clip is fixed on flexible pipe on hose coupling body, the circular arc muscle of buffering ring projection is gapped in clip arc groove, when hose coupling pressure-bearing, flexible pipe slowly expands with the pressure process that rises, buffering ring to clip near, protection clip, with there is no buffering ring comparison, protection one: hose pressure acts on clip by buffering ring, plays buffer function; Protection two: hose pressure is greater than radial component at buffering ring place axial thrust load, has alleviated the load that clip bears, and has improved clip bearing capacity.
