Description
Technical field
The invention belongs to technical field of taps, relate in particular to a kind of connection set of watertap discharging tube.
Background technique
Common be contained in water tap on the washbasin or in the kitchen for convenient in use, its outlet pipe can rotating certain angle.
Outlet pipe generally be socketed on connecting body that valve body is connected mutually on.In the rotation process of outlet pipe, can not break away from valve body in order to guarantee outlet pipe, between outlet pipe and connecting body, be provided with limit stoper.Common water tap generally all is to be provided with an annular recess on connecting body stretches into the outer side surface of outlet pipe, be provided with the stop screw through the water outlet tube wall in the corresponding position of outlet pipe, stop screw is screwed its inner end of back and is inserted in the aforesaid annular recess.Adopt this limit stoper, its deficiency is: the rotational stability that single stop screw can not fine assurance outlet pipe; After using a period of time, stop screw is loosening easily, and this can have influence on the rotation smoothness of outlet pipe, and can not avoid outlet pipe the generation of valve body phenomenon to occur breaking away from fully; Expose the beautiful shape that has also had influence on water tap in the lip-deep screw of outlet pipe outer end.
Summary of the invention
The objective of the invention is at the existing the problems referred to above of existing watertap discharging tube connecting device, a kind of watertap discharging tube connecting device of new structure is provided, after itself and water tap assemble, do not have influence on the attractive in appearance of water tap monnolithic case, outlet pipe change in shape scope is wide, be convenient to assembling and dismounting, outlet pipe stability of rotation, reliable.
Purpose of the present invention can realize by following technical proposal: a kind of watertap discharging tube connecting device, be arranged between the valve body and outlet pipe of water tap, comprise a columnar connecting body, connecting body is fixed on the valve body, and communicate with the osculum in the valve body, outlet pipe is placed on the connecting body, and can rotate around connecting body, it is characterized in that, there is a retaining edge connecting end inboard of described outlet pipe, end in connecting body is in outlet pipe connects a pressure cap that has center hole, and the outer of pressure cap is pressed on above-mentioned retaining along last.
In this connection set, push down the retaining edge of outlet pipe inboard by the outer of pressure cap, make outlet pipe can not break away from connecting body, but outlet pipe can rotate around connecting body, with the angle of conversion outlet pipe.When fastening piece is assembled or dismantles, can tool using extend into the operation that to finish in the outlet pipe pressure cap, and need not take valve body apart, assembling and convenient disassembly from the free end of outlet pipe.
In above-mentioned watertap discharging tube connecting device, the connecting end inner side surface of described outlet pipe is provided with joints sleeve, and joints sleeve and outlet pipe are connected, and the inner end of joints sleeve forms above-mentioned retaining edge.Form the retaining edge by joints sleeve, can simplify the preparation process of outlet pipe.
In above-mentioned watertap discharging tube connecting device, described pressure cap is a split-type structural, is made up of fastening piece and positioning cap, and described fastening piece passes positioning cap and is connected with connecting body by screw thread, described outer is located on the positioning cap, and this positioning cap is circumferentially fixing with respect to connecting body.Pressure cap adopts the positioning cap of split-type structural circumferentially fixing with respect to connecting body, when outlet pipe can make fastening piece when rotating can be not stressed, effectively stop fastening piece to rotate, make can keep outlet pipe and being connected of connecting body stablizing.
In above-mentioned watertap discharging tube connecting device, the diameter of described fastening piece outer end is less than the diameter of outer on the positioning cap.The requirement of diameter between the two, prevented outlet pipe grown service time after on inwall incrustation, it can drive fastening piece and follow together and rotate when rotating, thereby has guaranteed the stability in the outlet pipe rotation process.
In above-mentioned watertap discharging tube connecting device, described positioning cap has a polygonal hole, end in connecting body stretches into outlet pipe is provided with the positioning body that is connected as a single entity with connecting body, the outer side surface shape of described positioning body and the shape of positioning cap inner side surface match, positioning cap is socketed on this positioning body, and both are Spielpassung.The shape of positioning cap inner side surface and positioning body outer side surface helps making both to maintain a fixed, and is convenient to both sockets.
In above-mentioned watertap discharging tube connecting device, described joints sleeve and outlet pipe are provided with some opening slots towards an end in the outlet pipe outside for being threaded on joints sleeve, scribble tackiness agent in the threaded connection place of joints sleeve and outlet pipe.Being provided with opening slot is convenient in the connecting end of joints sleeve precession outlet pipe.When joints sleeve fully with after outlet pipe is connected, with tackiness agent joints sleeve is connected mutually with outlet pipe.
Compared with prior art, this watertap discharging tube connecting device advantage is:
1, do not have exposed screw on the outer surface of outlet pipe, can not influence the monnolithic case of water tap.
2, the outer on the pressure cap is pressed on and is located at the interior retaining of outlet pipe connecting end along last, and with respect to endwisely slipping of single screw restriction outlet pipe, it has higher stability, is not easy to damage.
3, pressure cap does not need to bear heavier power, and its axial dimension can be set to very little, and it is to the adaptability height of outlet pipe profile variation, and outlet pipe can have more profile variation to adapt to actual user demand.
