Description
Technical field
The utility model relates to water purification technology field, relates in particular to the linkage structure between filter water outlet and pipeline.
Background technique
Current filter water outlet, normally directly connects a pipeline, is provided with valve on pipeline.Screw thread turn between this pipe-and-filter, is usually closely to connect by screw thread, between pipeline and filter, turn can not occurs, once can be leaked.Between pipeline and filter, needing to rotate under the occasion of motion, not yet having the drive mechanism between filter and pipeline at present.
Summary of the invention
The purpose of this utility model is to provide one can guarantee sealing, can make again to rotate between the water outlet of filter and pipeline the filter seal drive mechanism of motion.
The utility model for the technological scheme that solves its technical problem and adopt is:
Filter seal drive mechanism, comprises swivelling pipe, and swivelling pipe outer surface has at least one groove near a side end face, in described groove, is provided with seal ring;
On described swivelling pipe outer surface, be also provided with bulge loop, described groove is between described bulge loop and the end face of described swivelling pipe;
Described swivelling pipe is established a reeded side and is inserted the water outlet of the filter core bottom of filter, described seal ring and described water outlet inwall close contact, and described water outlet and described swivelling pipe internal communication;
Described water outlet outside is provided with outside thread, and a nut sleeve is in described swivelling pipe outside and have internal thread, the outside thread of described water outlet and the screw-internal thread fit of described nut; Described nut internal diameter is greater than described swivelling pipe external diameter;
Described bulge loop below is provided with snap ring, and in the time that described nut screws, described snap ring and described bulge loop close contact.
Described snap ring and described nut are integrated, and described snap ring is eccentric snap ring.
Described groove is two.
The utility model filter seal drive mechanism guarantees that sealing is the groove that relies on swivelling pipe outer surface to have, and is provided with seal ring in groove, is provided with two even more seal rings, and sealing is better.The utility model filter seal drive mechanism guarantees that being connected between swivelling pipe and filter is the cooperation by bulge loop, snap ring, nut three.Nut is closely connected with filter water outlet by screw thread, and when nut screws, snap ring blocks bulge loop, now between swivelling pipe and filter, can only rotate, and can not depart from, and having realized can sealed rotational, the effect that can connect again.
Accompanying drawing explanation
Below, in connection with the drawings and specific embodiments, further the utility model structure is elaborated.
Fig. 1 is the utility model filter seal drive mechanism perspective exploded view.
Fig. 2 is the utility model filter seal drive mechanism schematic diagram.
Fig. 3 is that the utility model filter seal drive mechanism nut part master looks schematic diagram.
In figure: 1 swivelling pipe; 101 grooves; 102 bulge loops; 2 nuts; 201 snap rings.
Embodiment
Below in conjunction with accompanying drawing and example, the utility model is further described.In the drawings, size shown in does not represent actual size.Accompanying drawing is idealized embodiment's of the present invention schematic diagram, and embodiment shown in the present should not be considered to only limit to the given shape in region shown in figure, but comprises obtained shape, the deviation causing such as manufacture.Expression in figure is schematically, but this should not be considered to limit the scope of the invention.
As shown in Figure 1, 2, filter seal drive mechanism, comprises swivelling pipe 1, and swivelling pipe 1 outer surface has and in 101, two grooves 101 of two grooves, is provided with seal ring (omitting seal ring in figure) near a side end face.Seal ring can be the conventional sealing materials such as rubber, silica gel.On swivelling pipe 1 outer surface, be also provided with bulge loop 102, groove 101 is between bulge loop 102 and the end face of swivelling pipe 1.
When use, swivelling pipe 1 is provided with a side of groove 101 and inserts the water outlet (not shown) of the filter core bottom of filter, and water outlet and swivelling pipe 1 internal communication guarantee the circulation of water.Seal ring and water outlet inwall close contact, guaranteed the sealing between swivelling pipe 1 and water outlet inwall.
Water outlet outside is provided with outside thread, and a nut 2 is enclosed within swivelling pipe 1 outside and has internal thread, and the screw-internal thread fit of the outside thread of water outlet and nut 2, makes swivelling pipe 1 closely be connected with filter water outlet, can not come off.Nut 2 internal diameters are greater than swivelling pipe 1 external diameter.
Swivelling pipe 1 outer surface of upper bulge loop 102 belows are provided with snap ring 201.Snap ring 201 can be a separate part, also can be integrated with nut 2.
As shown in Figure 3, snap ring 201 is integrated with nut 2, and snap ring 201 is eccentric snap ring.In the time that snap ring 201 and nut 2 are integrated, and snap ring 201 is necessary for eccentric snap ring, otherwise the little bulge loop 102 that cannot overlap of diameter, diameter greatly cannot block bulge loop 102.Only have eccentric snap ring, after can guaranteeing to overlap bulge loop 102, while tightening, a part for snap ring 201 can be blocked bulge loop 102.Certainly, if snap ring 201 is separate part, can bias can be not eccentric yet.
When the utility model filter seal drive mechanism uses, first nut 2 be enclosed within on swivelling pipe 1 and cross bulge loop 102; A side that again swivelling pipe 1 is provided with to groove 101 is inserted the water outlet of the filter core bottom of filter, seal ring and water outlet inwall close contact; Screw nut 2, now snap ring 201 blocks bulge loop 102 again, between swivelling pipe 1 and filter, can only rotate, and can not depart from, and having realized can sealed rotational, the effect that can connect again.
