Description

Folding water cup

The utility model relates to a kind of folding water tumbler easy to carry.

A kind of Foldable telescopic cup is disclosed in CN86203829, it comprises bowl cover, folding tube is equipped with the folding wall of cup of elasticity that the compression spring is made, the cup end and the rim of a cup of fixedlying connected with lower end, the upper end of wall of cup respectively, bowl cover and cup are provided with the turn lock uint at the end, cup is being connected in a rim of a cup and a cup end, and can separate with the end not, coincide by rotating with the cambered surface of rim of a cup.Its weak point is: because wall of cup is to be closed by folding tube and compression spring set to form, cup is bellow-shaped, and the moulding utmost point is not attractive in appearance, is not suitable for doing daily drinking-water apparatus, and complex structure, the cost height.

The purpose of this utility model is to provide a kind of and simple in structurely has attractive appearance, folded formula water tumbler easy to use.

Technical solution of the present utility model is, comprise the rim of a cup and the folded formula water tumbler at the cup end, it is characterized in that becoming scalable cup shell by two pitch circle tube mutual sheathing at least, wherein the free port of outermost one pitch circle tube is fixedlyed connected with rim of a cup, the free port of the inside one pitch circle tube was fixedlyed connected with a glass end, cup is provided with a folding cup courage in the shell, and the opening of cup courage is fixedlyed connected with rim of a cup, is provided with under the extended state the fixedly locking device of usefulness between the adjacent two pitch circle tubes.

The utility model has the advantages that: because the utility model is by cup shell and Fordable cup courage be combined into stretching structure, the time spent compressedly is not overlapped into very little volume, and is easy to carry and store; As long as be drawn into user mode during use, and can be according to the volume and the height of the amount of being filled with water needs adjusting cup.Because cup is a glass shell and a cup courage double-decker, between the space have better thermal insulation performance, promptly can be made into folded formula thermos cup if be equipped with bowl cover with heat-insulating property.Advantages such as the utility model also has simple in structure, and assembly technology is simple, and is handsome in appearance, easy to use.

Following accompanying drawing has been described embodiment of the present utility model.
