FIG. 3 is an enlarged view of a portion of FIG. 1 at A;

in the figure: 1. interior cup, 2, shell, 3, passive piece, 4, slide bar, 5, circular arch, 6, fretwork piece, 7, spring, 8, fixed cover, 9, connecting rod, 10, stopper, 11, thermos cup bowl cover.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Please refer to fig. 1-3, the utility model relates to a folding vacuum cup, including shell 2, cup 1 in the internal connection, shell and interior cup are stainless steel, have guaranteed the heat preservation effect, the shell is connected with the gliding track of fixation pillar, and the slide bar 4 has been cup jointed inside the track, and fretwork piece 6 is installed to orbital inboard, one side of fretwork piece is connected with circular arch 5, and the opposite side of fretwork piece is connected with spacing spring 7, the other end contact slide bar of spring still includes the thermos cup bowl cover, continues to keep warm through the bowl cover of screwing behind the use thermos cup, through tensile slide bar 4, utilizes circular arch 5, the cooperation between fretwork dog 6 and the spring 7, changes the flourishing volume of thermos cup to change the volume of thermos cup, the user of being convenient for carries. The slide bar is spacing through passive piece when initial, has improved the stability of thermos cup, and the spring is in compression state and spring and fretwork piece lie in the same one side of slide bar this moment.

The during operation, upwards pulling slide bar, spring resume original length this moment, fretwork piece is connected to spring one side, opposite side contact slip track, and the slide bar lower extreme is located between fretwork piece and the spring this moment, carries on spacingly through the two. When folding the thermos cup, press circular protrusion, the spring is in compression state again this moment, and the slide bar slides back the bottom through the middle of the fretwork piece, and the thermos cup resumes fold condition. During operation again, upwards stretching the slide bar makes it pass through the fretwork piece, and the spring resumes former length again this moment, and the slide bar carries on spacingly through the two, the thermos cup volume grow.

The above is only a preferred embodiment of the present invention, but not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, improvement, equivalent structure or equivalent flow replacement within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
