A kind of accurate measurement measuring cup
Technical field
The utility model relates to a kind of accurate measurement measuring cup.
Background technology
Existing measuring cup generally all is single cup, if cup is wider, is to use at the metering larger volume, but when the metering smaller size smaller, less reading error can be brought error larger in the metering; If cup is narrower, when the metering smaller size smaller, the error in dipping that brings because of reading error can reduce, if but will measure larger volume with it, just need to increase the height of cup, cup will be more elongated like this, can affect the stability that cup is placed on the one hand, the cup opening is little on the other hand, can increase the difficulty of metering object falling.
The utility model content
The utility model purpose is to provide a kind of for the defective that prior art exists can measure smaller size smaller, can measure again the wider measuring cup of measures range of larger volume.
The utility model adopts following technical scheme for achieving the above object: a kind of accurate measurement measuring cup, and comprise and be with respectively graduated outer measuring cup and interior measuring cup, described interior measuring cup is fixed in the described outer measuring cup.
Preferably, described interior measuring cup is coniform.
The beneficial effects of the utility model: interior measuring cup is the little cone-shaped body in the large end, top, and convenient metering object falling is interior.If the less volume of metering, just with object falling in the interior cup of measuring cup, the graduation apparatus that reads by the interior cup gets final product.If the larger volume of metering, can spill in the outside measuring cup after in the interior cup of object falling at measuring cup, outside measuring cup is other corresponding reading, counts after the cup full-scale reading in this reading continues.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is vertical view of the present utility model.
Embodiment
Fig. 1, shown in Figure 2, for the wider measuring cup of a kind of measures range by the built-in interior measuring cup 2 of outer measuring cup 1, linking to each other by the bottom consists of.Outer measuring cup 1 and interior measuring cup 2 on one side scale coincide.Interior measuring cup 2 is the little cone-shaped body in the large end, top, and convenient metering object falling is interior.
During use, if the less volume of metering, just with object falling in the interior measuring cup 2 of measuring cup, the graduation apparatus that reads by the interior cup gets final product.If the larger volume of metering, can spill in the outer measuring cup 1 after in the interior measuring cup 2 of object falling at measuring cup, outer measuring cup 1 is other corresponding reading, counts after measuring cup 2 full-scale readings in this reading continues.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
