Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of water tap, particularly the linkage structure of Gai Liang watertap discharging tube.
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.
For this reason, the claimant applied for once that the patent No. was 2005200393505 " linkage structure of watertap discharging tube ".This structure as shown in Figure 2, it is arranged between the valve body 1 and outlet pipe 2 of water tap, is provided with connecting tube 3 and setting sleeve 4 between valve body 1 and the outlet pipe 2.Setting sleeve 4 passes connecting tube 3 and is screwed onto on the valve body 1, and the convex edge 41 on the setting sleeve 4 is pressed on the connecting tube 3, makes connecting tube 3 and setting sleeve 4 be connected in simultaneously on the valve body 1 by such structure.Outlet pipe 2 is enclosed within the end of connecting tube 3, has annular groove 21 one at the inner side surface of outlet pipe 2, and the positioning ring 5 that is enclosed within on the setting sleeve 4 is located in the annular groove 21.Because the circular hole of positioning ring 5 is eccentric, when setting sleeve 4 with after valve body 1 is connected fully, positioning ring 5 is protrusion outwards, thereby makes outlet pipe 2 can not break away from connecting tube 3, but can be around connecting tube 3 rotations.
As can be seen, in the above-mentioned bindiny mechanism, generally positioning ring 5 and outlet pipe 2 all adopt metallic material to make, and both can rub in rotation process at outlet pipe 2, produce some noises.Simultaneously, because the circular hole of positioning ring 5 is eccentric, the gap between annular groove 21 and the positioning ring 5 is inconsistent, and outlet pipe 2 just might be stuck in rotation process, and cause outlet pipe 2 to be rotated further.In addition, can rotate flexibly in order to make outlet pipe 2, the requirement on machining accuracy of positioning ring 5 is higher, and manufacture cost is also corresponding higher.
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 improvement is provided, noise free when its outlet pipe is rotated, and have characteristics simple in structure, easy to use, with low cost.
The purpose of this utility model can realize by following technical proposal: a kind of linkage structure of watertap discharging tube of improvement, be arranged between the valve body and outlet pipe of water tap, a connecting tube is arranged between valve body and the outlet pipe, outlet pipe is placed in the end of connecting tube, in outlet pipe and connecting tube, there is one and is setting sleeve cylindraceous, it is characterized in that, described connecting tube is connected with valve body by screw thread, setting sleeve is connected with connecting tube by screw thread, inner side surface at outlet pipe has an annular groove, be with a positioning ring on the setting sleeve, positioning ring is embedded in the above-mentioned annular groove, and positioning ring is pressed on its both sides by setting sleeve and connecting tube and is located.
In this linkage structure, owing to positioning ring is pressed between setting sleeve and the connecting tube, so positioning ring is fixed.Outlet pipe is placed on the connecting tube, and positioning ring is stuck in the annular groove of outlet pipe inner side surface, so outlet pipe axially is being fixed, can not break away from connecting tube, but can rotate around connecting tube.This just means that outlet pipe can rotate the direction that changes water outlet arbitrarily when water tap uses.
In the linkage structure of the watertap discharging tube of above-mentioned improvement, described positioning ring is made by having flexible plastic material.By such material, make outlet pipe in rotation process, can not make a noise; Directly put into annular groove after when product assembles, the positioning ring extruding can being dwindled simultaneously, be beneficial to the actual production of product.
As preferably, it is that material is made that above-mentioned positioning ring can adopt teflon or nylon.These two kinds of materials are more general, and have preferable performance.
In the linkage structure of the watertap discharging tube of above-mentioned improvement, described setting sleeve outer side surface has the convex edge, and above-mentioned positioning ring is pressed on the end of connecting tube by the convex edge with it.By such structure, make the fixed-site of setting sleeve motionless.
Compared with prior art, therefore the connection positioning means of the watertap discharging tube of this improvement can change the water outlet direction of water tap arbitrarily because outlet pipe can freely rotate with respect to connecting tube and valve body, makes the use of water tap convenient.Simultaneously, the positioning ring friction that outlet pipe is made at rotation process outlet pipe and plastic material, therefore, outlet pipe can not make a noise when rotating.
Because the side of positioning ring contacts with annular groove maintenance face on the outlet pipe all the time, therefore, situation about in rotating the outlet pipe process, can not block, and in rotation process, seem level and smooth, outlet pipe also is difficult to break away from connecting tube.In addition, the positioning ring manufacturing is simple, also suitable reduction cost.
Description of drawings
Fig. 1 is the sectional view of linkage structure of the watertap discharging tube of this improvement.
Fig. 2 is the schematic representation of the linkage structure of a kind of watertap discharging tube of the prior art.
Among the figure, 1, valve body; 11, water-guiding hole; 2, outlet pipe; 21, annular groove; 3, connecting tube; 4, setting sleeve; 41, convex edge; 42, water port; 43, teeth; 5, positioning ring; 6, seal ring.
Embodiment
As shown in Figure 1, a water-guiding hole 11 is arranged in the valve body 1, the current in the pipeline outwards flow out through the water-guiding hole 11 of valve body 1.The linkage structure of the watertap discharging tube of this improvement is arranged between the valve body 1 and outlet pipe 2 of water tap.Connecting tube 3 is between outlet pipe 2 and valve body 1, and outlet pipe 2 is enclosed within the end of connecting tube 3.Setting sleeve 4 is positioned at outlet pipe 2 and connecting tube 3, and setting sleeve 4 is cylindric its center a water port 42 that connects two ends, the left and right sides.
Connecting tube 3 is by being threaded on the valve body 1, and in the present embodiment, the position that connecting tube 3 contacts with outlet pipe 2 is provided with several sealed circle 6, prevents that by seal ring 6 joint of current between connecting tube 3 and outlet pipe 2 from leaking.Setting sleeve 4 is by being threaded on the connecting tube 3, and setting sleeve 4 inner side surface be provided with teeth 43.When assembling,, rotate assembly tool, just can drive setting sleeve 4 and rotate together, setting sleeve 4 is connected with valve body 1 as long as head is also had teeth and undersized to be inserted in the setting sleeve 4 in the assembly tool of setting sleeve 4 internal diameters.
The inner side surface of outlet pipe 2 has annular groove 21 one, is with a positioning ring 5 on the setting sleeve 4.When positioning ring 5 was embedded in the annular groove 21, positioning ring 5 also was crushed between setting sleeve 4 and the connecting tube 3, therefore made positioning ring 5 obtain the location.In the present embodiment, setting sleeve 4 outer side surfaces have convex edge 41, and positioning ring 5 just is crushed between the end of convex edge 41 and connecting tube 3.
In the present embodiment, it is that material is made that positioning ring 5 adopts teflon, has both had certain rigid, can snap in agley in the annular groove 21 when assembling again.Positioning ring 5 remains consistent with gap between the annular groove 21.When rotating outlet pipe 2, positioning ring 5 can not send very big noise with outlet pipe 2 frictions yet.
In the water tap using process, enter current in the valve body 1 successively behind water-guiding hole 11, water port 42, outwards flow out from outlet pipe 2.Obviously, as long as rotate outlet pipe 2, just can change the water outlet direction of water tap.
