Abstract
The utility model relates to a graduated cylinder for accurate and high-resolution volume measuring. A cavity is arranged at the lower part of the cylinder, which is communicated with the cylinder and has a diameter larger than that of the cylinder. A large part of chemicals can be held in the cavity with a larger diameter. The cylindrical diameter of the cavity can be set up for desired measurement accuracy, thereby reducing the total height of the graduated cylinder and improving measurement accuracy; in addition, since the cavity with a large diameter is used as the base, the cylinder is then kept from easily tipping and a wide range of product series can be made according to different volume classes, enabling different measuring resolutions and accuracies to be selected by selecting cylinder diameters, hence a strong flexibility in fluids volume measuring.
Description
Technical field
The utility model relates to a kind of volumetric metering utensil, especially relates to a kind of graduated cylinder.
Background technology
At present, existing graduated cylinder all is to adopt material such as glass to become the elongate cylinder type usually.For the material that satisfies different volumes such as the metering of liquid, granular solids etc., and produce not isometric graduated cylinder at different volume ranges.The main deficiency of this graduated cylinder is: 1, for the metering of liquid of larger volume etc., the volume of its graduated cylinder also will be made greatlyyer, thereby makes the height of graduated cylinder of its elongate cylinder type very high, is difficult for putting and depositing, and topples over easily and causes damage; 2, for the graduated cylinder of larger volume, its diameter is also relatively large, thereby causes the resolution of its graduated cylinder to reduce, and has influence on the precision of metering.
The utility model content
Technical problem to be solved in the utility model provides a kind of graduated cylinder that improves metering resolution and precision.
The technical scheme that its technical matters that solves the utility model adopts is: the cylindrical shell bottom at graduated cylinder is provided with the cavity volume that is communicated with cylindrical shell, and the diameter of cavity volume is greater than the diameter of cylindrical shell.
Further be the diameter maximum at the place, bottom of cavity volume.
The beneficial effects of the utility model are: owing to be provided with the cavity volume that is communicated with cylindrical shell in the cylindrical shell bottom of graduated cylinder, and the diameter of cavity volume is greater than the diameter of cylindrical shell, thereby the material that can utilize its large diameter cavity volume splendid attire major part to be measured, utilization is carried out accurate measurement than the cylindrical shell of minor diameter, the diameter of its shell portion can be provided with its diameter according to required measuring accuracy, thereby can also can improve measuring accuracy and reduce the overall height of graduated cylinder; Simultaneously, utilize larger-diameter cavity volume as base, not only can improve the stability of graduated cylinder, also can be according to the interval series of products that are fit to the different volumes metering of making of different volumetric meterings, made things convenient for user's use, adjust the diameter of cylindrical shell and can adjust metering resolution and precision easily, adaptability is strong, can be widely used in having the volume metering of mobile material.
Description of drawings
Fig. 1 is a front view of the present utility model.
Be labeled as among the figure: cylindrical shell 1, cavity volume 2.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, graduated cylinder of the present utility model comprises cylindrical shell 1, and cylindrical shell 1 is provided with scale mark and is used for metering.Be provided with the cavity volume 2 that is communicated with cylindrical shell 1 in the bottom of cylindrical shell 1, the diameter of cavity volume 2 is greater than the diameter of cylindrical shell 1, thereby the material that can utilize large diameter cavity volume 2 splendid attire major parts to be measured, and carries out accurate measurement with the cylindrical shell 1 that is provided with scale mark.Simultaneously, because the diameter of cavity volume 2 utilizes the base of larger-diameter cavity volume 2 as graduated cylinder greater than the diameter of cylindrical shell 1, make its stability better, and can effectively reduce the overall height of graduated cylinder.According between different containment volume, also can make the series of products that are fit to the different volumes physical measurement, the diameter of adjusting cylindrical shell 1 can be adjusted the resolution and the measuring accuracy of graduated cylinder easily, and adaptability is strong.
Better for the stability that makes its graduated cylinder, preferably the diameter that the bottom of cavity volume 2 is located is made maximumly or is relatively large.The shape of cavity volume 2 can be taper, semisphere, billiard table shape, truncated cone-shaped etc., and these all usual shapes that adopt repeat no more here.
Claims (2)
1, graduated cylinder comprises cylindrical shell (1), it is characterized in that: be provided with the cavity volume (2) that is communicated with cylindrical shell (1) in the bottom of cylindrical shell (1), the diameter of cavity volume (2) is greater than the diameter of cylindrical shell (1).
2, graduated cylinder as claimed in claim 1 is characterized in that: the diameter maximum at the place, bottom of cavity volume (2).
