Description

Plug-in liquefied gas rubber tube connection assemble

The utility model relates to the connection set between a kind of liquid gas cooking stove and the liquified petroleum gas cylinder, and particularly a kind of inserting mode that can adopt connects fast, and can prevent the liquid gas sebific duct connecting assembly that leaks gas.

Be connected with reduction valve on being contained in the liquefaction bottle by sebific duct between existing liquid gas cooking stove and the liquified petroleum gas cylinder.By national strict regulations, each ventilation should be sent to the liquefied gas station aeration together with liquified petroleum gas cylinder and dress reduction valve thereon; Like this, the safety in the time of could guaranteeing aeration and transportation.But above-mentioned situation all will be loaded and unloaded leather hose at every turn, and is both time-consuming, require great effort again, and very dangerous.

The purpose of this utility model is to provide a kind of and can loads and unloads easily, can guarantee its effective sealing again, prevents the plug-in type liquid gas sebific duct connecting assembly that leaks gas.

Plug-in type liquid gas sebific duct connecting assembly comprises the socket assembly that links to each other with the liquid gas cooking stove sebific duct and the plug assembly two-part that link to each other with reduction valve sebific duct on the liquified petroleum gas cylinder.The socket assembly comprises that the rear end takes the hollow socket body of gas joint out of, be contained in the telescopic cushion rubber tube that seals in the socket, be enclosed within the spring I between the outer two-port flange of cushion rubber tube, place the thimble at socket socket center, be enclosed within the gripping mechanism that socket is outer, control is contained in the steel ball that plays the role of positioning on the socket walls.Stir this device, can tighten or take off being connected of socket assembly and plug assembly automatically.Plug assembly is by plug body, is contained in the air inlet Sealing in the plug body port, be plugged on the air input joint at plug body rear portion and place air input joint and Sealing between the spring III form.Have the arc-shaped slot that matches with steel ball on the socket socket on the plug body forward outer surface.

Below in conjunction with embodiment shown in the drawings the utility model is explained in detail.

Fig. 1 is the utility model socket assembly and plug assembly connection diagram, and Fig. 2 is a socket assembly schematic representation, and Fig. 3 is the plug assembly schematic representation.Among the figure: 1, air outlet adapter, 2, overcoat, 3, the spring I, 4, the cushion rubber tube, 5, the spring II, 6, socket, 7, pressure cap, 8, steel ball, 9, thimble, 10, plug body, 11, air input joint, 12, sebific duct, 13, Sealing, 14, the spring III, 15, O shape circle, 16, packing ring, 17, protecting cover.

With reference to figure 2, the rear end is taken the socket 6 of gas joint 1 out of on the socket assembly, have annular ring recess in the middle of in it, be equipped with telescopic, the cushion rubber tube 4 that seals on the ring recess and be enclosed within spring 13 between the cushion rubber tube 4 outer two-port flanges, be with " L " shape packing ring 16 on the front flange, the sheath of these packing ring 16 double as cushion rubber tubes 4 front ports; Spring 13 natural lengths just push up straight cushion rubber tube 4.Have 3 or 4 steel ball 8 mounting holes being evenly distributed on the annular wall on the socket 6 front end sockets, mounting hole is taper, and upper and lower, hole diameter is slightly larger than and is slightly less than steel ball 8 diameters respectively, and the diameter of steel ball 8 is greater than the thickness 2-3mm of socket walls.Be contained in the thimble 9 at socket center, the inwall of the support at its rear portion and socket 6 is connected as a single entity.

Be installed in steel ball 8 usefulness in the cone shape hole and slide over socket 6 sockets pressure cap 7 outward and push down, the inwall of pressure cap 7 has a stage, is harmonious with the defining flange of socket 6 ports.Roof pressure has spring II 5 and is enclosed within outside the socket 6, has two overcoats 2 that are respectively applied for the spacing stepped shaft step of spring II 5 and pressure cap 7 on its inwall pressure cap 7 the other ends.

With reference to figure 3, plug assembly comprises that inwall has the plug body 10 of secondary stepped shaft circle platform, the air input joint of be plugged on the plug body 10 back circle platforms, also fixing 11 with protecting cover 17, air input joint 11 rear portions link to each other with reduction valve sebific duct 12 on the liquified petroleum gas cylinder, air input joint 11 front inner wall have the stair ring platform, circle is equipped with spring III 14 on the platform, and the other end of spring III 14 is to be enclosed Sealing 13 on the platform by roof pressure before plug body 10; The zero shape circle 15 of sealing is housed between air input joint 11 and plug body 10 inwalls, and there is circular groove at Sealing 13 rear portions, are used for fixing spring III 14, and seal diameter is less than plug body 10 intermediate inner wall diameters, greater than the front inner wall diameter; Have the locating groove that matches with steel ball 8 on plug body 10 forward outer surface, the curved end of the face that draw-in groove cuts or flat V-arrangement, the inclination angle, bi-side is 45 °.Plug body 10 tops are the face that inclines, and the inclination angle is 45 °-60 °, match with cushion rubber tube 4 ports in the socket 6.

The utility model in use, push the pressure cap 7 of socket assembly backward with hand, make the step in the pressure cap 7 leave the position of pushing down steel ball 8, make steel ball 8 be loosening state, treat to unclamp pressure cap 7 again after plug assembly is pegged graft, spring II 5 is pushed pressure cap 7 to the place ahead makes pressure cap 7 interior steps pressures block steel ball hole again, and steel ball 8 is pushed in the hole, steel ball 8 just in time is stuck in the draw-in groove place of plug body 10 in socket 6 socket inwall exposed portions serve, with reference to figure 1.At this moment, plug assembly and socket assembly are chucking, sealing, aeration status, and promptly the thimble 9 on the socket 6 has backed down Sealing 13 sealing stations in the plug body 10, and plug body 10 ports top is combined on socket 6 O-ring seal tubes 4 port inner walls.When needing demolition, with hand pressure cap 7 is dialled backward, spring II 5 is compacted, and make the position that moves away shutoff steel ball 8 behind the step in the pressure cap 7, steel ball 8 is in the hole freely becomes flexible state, then can easily dial down plug assembly, and 13 sealings of the Sealing in the plug body 10, plug assembly is closed gas.So both reached purpose easy to use, can prevent gas leakage again.

Obviously, the utlity model has easy to operately, compact conformation is reasonable, and the advantages such as good airproof performance can be widely used in being connected between family's gas-cooker and the liquefied gas bottle.
