Description
Technical field
The utility model belongs to field of mechanical technique, relates to the linkage structure of outlet pipe in a kind of water tap, particularly water tap.
Background technique
In the common water tap, outlet pipe and valve body are fixed together.Outlet pipe can not rotate, and can't change the water outlet direction of water tap.
In Kitchen tap, outlet pipe is placed on the valve body, can rotate around valve body.The joint of outlet pipe and valve body seals by seal ring.This sealing configuration leakage phenomenon occurs easily after tap uses a period of time.Simultaneously, this structure more complicated of outlet pipe in Kitchen tap, manufacture cost is higher, is not suitable for the water tap of common occasion.
Summary of the invention
The purpose of this utility model is at the existing the problems referred to above of existing water tap, and a kind of linkage structure of watertap discharging tube of novelty is provided, and makes its outlet pipe rotatable, and has characteristics simple in structure, easy to use, with low cost.
The purpose of this utility model can realize by following technical proposal: the linkage structure of this watertap discharging tube is arranged between the valve body and outlet pipe of water tap, it is characterized in that, a connecting tube is arranged between described valve body and the outlet pipe, outlet pipe is placed in the end of connecting tube, and outlet pipe is axially fixed on the connecting tube, have one and be setting sleeve cylindraceous in outlet pipe and connecting tube, setting sleeve is connected with valve body by screw thread, and connecting tube and valve body are fixed together.
In this linkage structure, owing to outlet pipe is axially fixed on the connecting tube, so outlet pipe can not break away from connecting tube.But outlet pipe can reverse around connecting tube, that is to say after whole water tap is fixing to rotate the direction that outlet pipe changes water outlet arbitrarily.
In the linkage structure of above-mentioned watertap discharging tube, the inner side surface of described connecting tube has a shoulder block, at the outer side surface of setting sleeve the convex edge is arranged, and the convex edge is pressed on the shoulder block.Push down the shoulder block of connecting tube by the convex shoulder of setting sleeve, make firm the linking together of connecting tube and setting sleeve.
In the linkage structure of above-mentioned watertap discharging tube, the inner side surface of described setting sleeve has non-circular surface.In making connecting tube and valve body connection procedure, need the rotating position cover.The utility model is to utilize the inboard non-circular surface of setting sleeve, adopts with the be complementary assembly tool of profile of setting sleeve inner side surface and inserts in the setting sleeve, finishes the attended operation of this structure by rotating assembly tool.
In the linkage structure of above-mentioned watertap discharging tube, the inner side surface of described outlet pipe has an annular groove, annular groove is in the joint of outlet pipe and connecting tube, a positioning ring is arranged in the end of connecting tube, the circular hole that an off-centre is arranged in the positioning ring, positioning ring are placed in the setting sleeve, and the rear portion external diameter of setting sleeve is greater than the middle part external diameter, and the end of setting sleeve is a retaining edge, and the external diameter on retaining edge is greater than the internal diameter of positioning ring.
Utilize circular hole eccentric in the positioning ring, in setting sleeve and valve body connection procedure, positioning ring is snapped in the annular groove of outlet pipe inner side surface.Simultaneously, because the retaining of setting sleeve makes positioning ring can not break away from setting sleeve along blocking positioning ring,, but can rotate around connecting tube so outlet pipe can not break away from connecting tube.
Also can adopt another kind of structure, the inner side surface that is described outlet pipe has an annular groove, annular groove is in the joint of outlet pipe and connecting tube, and there is a draw-in groove position corresponding to annular groove in the connecting tube outside, between draw-in groove and the annular groove location piece is housed.
Embed draw-in groove and annular groove by location piece, just can make outlet pipe and connecting tube axial restraint.Particularly, location piece embeds and to have limited outlet pipe in the annular groove with respect to the moving axially of connecting tube, and makes outlet pipe can't break away from connecting tube, but can make the rotation of outlet pipe around connecting tube equally.
In the linkage structure of above-mentioned watertap discharging tube, described draw-in groove connects the interior outside of connecting tube, and the rear portion of setting sleeve has the external diameter bigger than the middle part, and the end of setting sleeve is pressed on the draw-in groove place.Utilize the rearward end of setting sleeve to withstand location piece, location piece is in draw-in groove and the annular groove all the time, thereby guaranteed being connected of outlet pipe and connecting tube.
Compared with prior art, the utlity model has following advantage:
1, because in this linkage structure, outlet pipe can freely rotate with respect to connecting tube and valve body, so can change the water outlet direction of water tap arbitrarily, makes the use of water tap convenient, has improved the use value of water tap.
2, by setting sleeve connecting tube and valve body are fixed together, make not only that manufacturing process and product is simplified, assembling easily, and product is simple in structure, can reduce manufacture cost.
