Description
The utility model relates to the pipe joint technical field, relates in particular to connect aluminium-plastic composite pipe quick coupling technical field.
Along with improving constantly of living standards of the people, carry the quality of facility for improving people's Drinking Water, various novel tubes and fitting emerge in large numbers on market one after another, in the hope of replacing galvanized iron conduit and the irony fitting of progressively being eliminated in the use field, wherein potentiality are big, especially with material-saving, quality is good, outward appearance is beautiful, withstand voltage height, antileakaging thin-wall stainless steel and thin-wall stainless steel pipe connector be for.But the thin-wall stainless steel that occurs on the market and thin-wall stainless steel pipe connector and gun and relative method all exist deficiency to some extent.Also have aluminium-plastic composite pipe also to be applied in large quantities on the New Residential Quarters water supply pipe by people gradually simultaneously, so thin-wall stainless steel and aluminium-plastic composite pipe connectivity problem occur, connecting means is now seen and mainly is divided into the loose joint formula and connects dead formula two big classes.One loose joint formula is that the internal and external screw thread by fitting cooperates, and realizes being connected of pipe and fitting, and as the patent No. 97211578.1 Chinese patents, characteristics are: dismounting flexibly, shortcoming are that cost of production is higher relatively; Two connect dead formula, be that welding, splicing or riveted joint by fitting and pipe realizes being connected of pipe and fitting, it as the patent No. 95200830.0 Chinese patent, characteristics are that the connection of the relative screw-thread fit of cost of production is low, and shortcoming is that installation difficulty is big or must cause the fitting of having adorned to scrap during dismounting again because of need not in place are installed.
First purpose of the present utility model be to provide a kind of without screw-thread fit, dismounting flexibly, be exclusively used in the quick coupling that connects flexible tubes such as aluminium-plastic composite pipe.
Second purpose of the present utility model is to provide a kind of and need not be threaded, dismounting flexibly, be exclusively used in the quick coupling that is connected between the thin walled tubes such as flexible tubes such as connecting aluminium-plastic composite pipe and Stainless Steel Tube.
The utility model realizes that the technological scheme of first purpose is: this quick coupling, include union body, union body has the interface that connects adapter, it is characterized in that: connecting the flexible tube interface changes the button overcoat for the flexible tube end is with, change button overcoat end and have many inner spline grooves, afterbody is with conical sleeve, this interface outer surface is with simultaneously changes cover in the button, changeing the interior cover of button forward outer surface is the conical surface that cooperates with conical sleeve, and and be lined with seal ring between the flexible tube, there is the external splines teat that cooperates with inner spline groove the centre, to change the interior cover of button external splines and push inboard in the commentaries on classics button overcoat inner spline groove, turn to and interlock, interface and flexible tube end are coupled together.
The utility model realizes that the technological scheme of second purpose is: on the technique scheme basis, interface has the thin walled tube of connection interface, its structure has toroidal cavity for the interface internal surface, taking over convex outer surfaces inboard and interface internal surface is lined with between the outer surface and the protruding seal ring that cooperates with taking over, the interface end has many inner spline grooves, other has the pipe clamping sleeve that is enclosed within the adapter convex outer surfaces outside, its end face has the external splines teat that cooperates with inner spline groove, insert in the interface when taking over an end, pipe clamping sleeve external splines is pushed inner spline groove inboard, interface end, and putting in place interlocks after turning to couples together interface and thin walled tube end.Also can be on the technological scheme basis of first purpose, interface has the thin walled tube of connection interface, its structure has toroidal cavity for the interface internal surface, take on the end card and block pipeloop, be lined with seal ring and pad circle between card pipeloop inboard and interface internal surface and the adapter outer surface, the interface end has many inner spline grooves, other has the pipe clamping sleeve that is enclosed within the adapter outer surface card pipeloop outside, its end face has the external splines teat that cooperates with inner spline groove, insert in the interface when taking over an end, pipe clamping sleeve external splines is pushed inner spline groove inboard, interface end put in place to interlock after turning to interface and thin walled tube end are coupled together.
Quick coupling of the present utility model does not need screw-thread fit, and production and processing is easy, cost is low, and dismounting flexibly, and it is convenient to install, and compressive strength is big after installing, and is difficult for leaking, and connects use on suitable especially aluminium-plastic composite pipe, the stainless-steel thin-wall pipe.
