Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments, the description of which is only exemplary and explanatory, and should not be construed as limiting the scope of the present invention in any way.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

As shown in fig. 1 to 5, an embodiment of the present invention provides a portable capacity-expandable cup, which includes a cup body 1, a capacity-expandable cup body 2, and a cover 3, wherein a first thread groove 11 and a second thread groove 12 are respectively formed at the top and the bottom of an inner cavity of the cup body 1, a first internal thread ring 22 and a second internal thread ring 23 are respectively formed at the top and the bottom of an outer wall of the capacity-expandable cup body 2, an external thread ring 21 is arranged below the first internal thread ring 22 on the outer wall of the capacity-expandable cup body 2, a cover thread groove 31 is formed on an inner wall of the cover 3, the first internal thread ring 22 and the second internal thread ring 23 are both in threaded connection with the cover thread groove 31, the external thread ring 21 is in threaded connection with the second thread groove 12, and the second internal thread ring 23 is in threaded connection with the first thread groove 11.

Wherein, the upper and lower parts of the dilatation cup body 2 are provided with openings; the externally threaded ring 21 has an outer diameter larger than the first and second internally threaded

rings

22 and 23.

Specifically, the cup body 1, the expansion cup body 2 and the cover 3 can be made of plastic, metal or glass.

The working effect of the utility model is as follows:

in the above scheme, by adding the expansion cup body 2, when the cup needs to be stored, in order to avoid occupying space, the expansion cup body 2 can be rotatably inserted into the bottom of the cup body 1 through the threaded connection between the second internal thread ring 23 and the second thread groove 12, so as to complete the storage effect;

among the above-mentioned scheme, when the volume of cup is increased to needs, dismantle out with the rotation of dilatation cup 2, reverse 180 degrees after that, with external

screw thread ring

21 and 11 threaded connection of first thread groove, accomplish dilatation cup 2 and cup body 1's installation, this is the mounting means of second kind, after that the volume of cup will greatly increased, be convenient for connect and get more drinking water, the practicality is strong.
