Abstract
The swivel bayonet type quick joint for metal pipes are pipes in the pipe lines of gas and liquid without any accessories, which can be used by rotating a circle after the metal pipe or the nylon pipe being plugged into the joint. The utility model is characterized in that the rubber sealing ring is fitted into the card core to function as sealing. The card core is fixed on the upper end of the fittings body. An outer covering body is covered around the card core by screw thread fits. A ring belt bulged with arris is in the card core. An inner cone face is carted on the inner wall of the body. When the outer body is rotated, the metal pipes or the nylon pipes are compacted. The utility model is widely used as the pipe coupling of gas and liquid in national defence, oil refining, chemical industry, light industry, aviation, textiles, ship building, medicine, machines, etc.
Description
The utility model is a kind of joint in gas and the liquid line, is widely used in the gas of systems such as national defence, oil refining, chemical industry, light industry, aviation, weaving, shipbuilding, medicine, machinery, the pipe joint in the liquid dress road, and pressure can bear 32kgf/cm
2So, also can be applicable to water supply pipe.
Domestic pipe joint kind of producing is a lot of at present, as FERRULETYPE, two FERRULETYPE, welding type, flared type, thread type etc., its common point all needs nut, collar, seal ring etc. be parts independently, and these parts are combined into joint when using installation, and operation is extremely inconvenient, component are easily lost again, the big and cost height of volume.
The purpose of this utility model provides and a kind ofly all is fixed on seal ring, the card heart, overcoat in the fittings body, not with the swivel bayonet type metal tube rapid pipe joint of any component, during use metal tube is inserted in the fittings body, the about circle of clockwise direction rotational shell can use, rotation counterclockwise can be taken out metal tube, can use repeatedly.
The purpose of this utility model is achieved in that the intracardiac hole of the card rubber seal of packing into, seal, the card heart is fixed on the fittings body upper end, be with frame in card heart periphery, use screw-thread fit, core-clipping vehicle has six sulculuses and the periphery conical surface, and protrude the corner angle astragal at the intracardiac hole circle Zhou Youyi bar of card, frame inwall car has interior all conical surfaces, when the rotational shell body, all conical surfaces in the frame force the periphery conical surface that has sulculus inwardly to contract, protrude the corner angle astragal and tightened metal tube thereby block one of intracardiac hole, so reached not metallic pipe coupling with any component.
Embodiment: described in detail in conjunction with the accompanying drawings
Fig. 1 is swivel bayonet type metal tube and nylon tube quick coupling structure figure
Fig. 2 is the card hearty cord composition among Fig. 1
Fig. 3 is the outer shell construction figure among Fig. 1
Put into according to rubber seal 5 shown in Figure 1 and will block the heart again behind the card heart 2 endoporus and be fixed on fittings body 6 upper ends with glue, frame 4 is inserted in the periphery of the card heart, frame 4 internal threads are spun on the outside thread of the card heart 2 and cooperatively interact, in the inside roll extrusion of frame 4 lower end peripheries, the formation bent side face 7 that concaves prevents that frame 4 from rotating through pine and come off.
According to shown in Figure 2, core-clipping vehicle has 6 sulculuses 11 and the periphery conical surface 3, and the card heart 2 endoporus circumference are processed with one and protrude corner angle astragal 8.Frame 4 inwalls and for example shown in Figure 3 are provided with inner conical surface 1.
During use metal tube 10 inserted fittings bodies 6 and pass the endoporus of frame 4, through blocking the heart 2 and rubber seal 5 bottom to fittings body 6, rubber seal 5 internal diameters require the external diameter less than metal tube, so form sealing state, turn clockwise about frame 4 one circles thereupon, all conical surfaces 1 produce a downward power in the frame 4, the compressing card heart 2 periphery conical surfaces 3, therefore the periphery conical surface that forces the card heart 2 to have sulculus inwardly compresses, a protrusion corner angle astragal 8 that blocks the heart 2 endoporus this moment is pressed on the metal tube periphery, reaches the purpose of chucking metal tube.With frame 4 counterclockwise revolve turn around about, frame 4 inner conical surfaces leave the card heart 2 upper end conical surfaces, and metal tube just can take out, and the material selection 65MN spring steel of the card heart 2 is good, the card heart 2 is convenient to spreading when Overheating Treatment is used, favourable taking-up metal tube.
Embodiment two, with same structural principle, insert a metal sleeve 10 at fittings body 6 centers, and are fixed on fittings body 6 lower ends, and this joint just can be used for nylon tube, and the Buddhist nun shows that nylon tube 9 inserts the metal tube 9 that is fixed on the fittings body 6 and just can use outward as shown in Figure 1.
The utility model volume is little, is not with annex, takes over and tear open pipe conveniently, the energy Reusability, and metal and nylon tube all can use.
