Description
Technical field
The utility model relates to one way of life apparatus, specifically a kind of variable capacity water tumbler.
Background technology
Water tumbler is daily daily necessities, at present water tumbler major part is on the market the water tumbler of fixed volume, but the amount of drinking water difference in different required for people, when sometimes needing to carry, also wish the volume that can change cup, at this moment the cup of fixed capacity just can not have been satisfied the demand.For addressing this problem, also occur that some design, as Chinese patent, publication number is 203493031U variable-displacement insulating cup, this design well achieves the change of water tumbler capacity, but its structure is comparatively complicated, and particularly its water bag takes regular exercise and easily damages; And for example Chinese patent, publication number is 201718932U portable cup, although this design can change capacity, this design adopts entire body screw thread, and waste time and energy during use, particularly water tumbler does not consider sealing, have impact on practical application.
Summary of the invention
For overcoming the problem of above-mentioned water tumbler, the utility model provides a kind of and uses variable capacity water tumbler that is reliable, quick, good airproof performance.
To achieve these goals, the utility model proposes a kind of technical scheme: a kind of variable-displacement water tumbler, is made up of outer cup, inner core, sealing ring, bowl cover.Described outer cup is round cup shape shape, and formation bulge loop is inwardly stretched in the upper end of outer cup, and bulge loop inner face has internal thread, has an annular groove, stud with sealing ring in annular groove in the bottom of outer cup.Described inner core is a tube-like piece, and its upper end is provided with external screw thread and internal thread, and its lower end is provided with another external screw thread, under this external screw thread edge inner core on have a bulge loop.There is an annular groove above bulge loop, in annular groove, stud with sealing ring.The internal thread of outer cup upper end can screw with the external screw thread of inner core upper end or lower end.Described bowl cover is provided with external screw thread, and along there being a flange on external screw thread, flange lower surface is provided with a sealing ring, and the internal thread of inner core upper end is with the external screw thread coupling on bowl cover, and for screwing bowl cover, bowl cover and inner core are sealed by bowl cover sealing ring.
Utility model works process is: when as low capacity water tumbler, and the external screw thread of inner core upper end screws with the internal thread of outer cup, and inner core screws downwards simultaneously, makes sealing ring at the bottom of the annular cup bottom inner core lower surface and outer cup be close to seal and form cavity volume.When will as Large Copacity water tumbler time, upwards screw inner core, the external screw thread of the upper end of inner core is departed from the internal thread of outer cup, upwards pull inner core again, the external screw thread of inner core lower end is contacted with the internal thread of outer cup, upwards screw again, make the lower surface of the inner core sealing ring on the bulge loop of inner core lower end and outer cup upper end bulge loop be close to sealing, form the cavity volume that cup is higher.
Above-mentioned sealing ring can be o RunddichtringO, also can be U-shaped plastic sealing ring.
Above-mentioned outer cup, inner core, bowl cover can be metal materials, also can be the mixtures of plastic material or this bi-material.
The beneficial effects of the utility model: structure is simple, and processing performance is good, sealing property is reliable, easy to use, stable, can make water tumbler volume-variable, also can carry by convenient water cup.

Detailed description of the invention
As shown in Fig. 1, Fig. 2, Fig. 3.Described outer cup is round cup shape shape, and the upper end of outer cup 2 is inwardly stretched into and formed bulge loop 2b, and bulge loop 2b inner face has internal thread 2a, has an annular groove in the bottom of outer cup 2, sealing ring 6 at the bottom of studding with in annular groove glass.Described inner core 3 is a tube-like piece, and its upper end is provided with external screw thread 3c and internal thread, and its lower end is provided with another external screw thread 3a, under this external screw thread 3a edge inner core on have a bulge loop 3b, have an annular groove above bulge loop 3b, in annular groove, stud with inner core sealing ring 5.The internal thread 2a of outer cup 2 upper end can screw with the external screw thread 3a of the external screw thread 3c of inner core 3 upper end or lower end.Described bowl cover 1 is provided with external screw thread 1a, and along there being a flange on external screw thread 1a, flange lower surface is provided with a bowl cover sealing ring 4, and the internal thread 3d of inner core 3 upper end mates with the external screw thread 1a on bowl cover, and for screwing bowl cover, bowl cover 1 and inner core 3 are sealed by bowl cover sealing ring 4.
The course of work of the present utility model is: as shown in Fig. 1, Fig. 3, when as low capacity water tumbler, the external screw thread 3c of inner core 3 upper end screws with the internal thread 2a of outer cup 2, and inner core 3 screws downwards simultaneously, makes sealing ring 6 at the bottom of the annular cup bottom inner core 3 lower surface and outer cup 2 be close to seal and form cavity volume.As shown in Fig. 2, when will as Large Copacity water tumbler time, upwards screw inner core 3, the external screw thread 3c of the upper end of inner core 3 is departed from the internal thread 2a of outer cup 2, upwards pull inner core 3 again, the external screw thread 3a of inner core 3 lower end is contacted with the internal thread 2a of outer cup 2, more upwards screws, make the inner core sealing ring 5 on the bulge loop 3b of inner core 3 lower end be close to sealing with the lower surface of outer cup 2 upper end bulge loop 2b, form the cavity volume that cup is higher.
