Abstract
The utility model discloses a measuring cylinder capable of accurate measuring. The measuring cylinder comprises a straight cylinder, wherein a semispherical containing cavity communicated with the straight cylinder is connected to the lower portion of the straight cylinder, a base is connected below the containing cavity, a liquid drainage hole communicated with the containing cavity is formed in the base, a rubber plug is arranged on the liquid drainage hole, the volume of the containing cavity is five times that of the straight cylinder, and the area of the bottom surface of the base is larger than the area of the bottom of the containing cavity. According to the measuring cylinder, due to the fact that the semispherical containing cavity is connected below the straight cylinder, the volume of the containing cavity is five times that of the straight cylinder, the height of the measuring cylinder can be remarkably reduced under the condition of the same volume, and therefore the stability is enhanced and the measuring cylinder is prevented from being knocked down. Due to the fact that the diameter of the straight cylinder is smaller, the straight cylinder is higher in accuracy; the liquid drainage hole communicated with the containing cavity is formed in the base, the rubber plug is arranged on the liquid drainage hole, and therefore the amount of liquid in the measuring cylinder can be accurately controlled when the liquid exceeds the required amount.
Description
Technical field
The utility model belongs to experiment equipment field, is specifically related to a kind of graduated cylinder of accurate measurement.
Background technology
Graduated cylinder is a kind of utensil for metering liquid volume, generally adopts glass to make growth tubular.What capacity will do more greatly is higher thicker.So just there are three problems: the one, easily knock damage over, the 2nd, reading accuracy is poor, and the 3rd, bad adjusting during the regulator solution scale of construction, after liquid has been added, can only topple over from graduated cylinder mouth, often cannot be accurate, need to repeatedly topple over, add the scale that just can reach needs.
Utility model content
The utility model object is to provide a kind of graduated cylinder of accurate measurement, solves existing graduated cylinder and easily knocks damage and the poor problem of precision over.
The technical solution of the utility model is: a kind of graduated cylinder of accurate measurement, comprise straight tube, described straight tube bottom is connected with the hemispheric cavity volume being communicated with straight tube, under cavity volume, be connected with base, on described base, have the outage that is communicated with cavity volume, on described outage, be provided with rubber plug, the volume of described cavity volume is 5 times of straight tube volume, and the floorage of described base is greater than the area of cavity volume bottom.
The utility model compared with prior art tool has the following advantages:
The utility model by connecting hemispheric cavity volume under straight tube, and the volume of described cavity volume is 5 times of straight tube volume, under same capability, can significantly reduce the height of graduated cylinder, thereby strengthen stability, prevents from knocking over.Because straight tube diameter is more tiny, it is accurately also just higher, has the outage that is communicated with cavity volume on described base, on described outage, is provided with rubber plug, when liquid exceedes demand, can fine adjustment graduated cylinder in the amount of liquid.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, Reference numeral is: 1-straight tube, 2-cavity volume, 3-base, 4-outage.
Embodiment
As shown in Figure 1, a kind of graduated cylinder of accurate measurement, comprises straight tube 1, described straight tube 2 bottoms are connected with the hemispheric cavity volume 2 being communicated with straight tube 1, cavity volume is connected with base 32 times, has the outage 4 that is communicated with cavity volume 2 on described base 3, on described outage 4, is provided with rubber plug.The volume of described cavity volume 2 is 5 times of straight tube 1 volume, so just can significantly reduce the diameter of straight tube 1 and overall height.The floorage of described base 3 is greater than the area of cavity volume bottom.So just can increase stability, prevent from knocking over because of carelessness.
The utility model is by connecting hemispheric cavity volume 2 for 1 time in straight tube, and the volume of described cavity volume 2 is 5 times of straight tube 1 volume, under same capability, can significantly reduce the height of graduated cylinder, thereby strengthens stability, prevents from knocking over.Because straight tube 1 diameter is more tiny, it is accurately also just higher, has the outage 4 that is communicated with cavity volume 2 on described base 3, on described outage 4, is provided with rubber plug, when liquid exceedes demand, can fine adjustment graduated cylinder in the amount of liquid.
The above embodiment has only expressed the application's embodiment, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the application's protection domain.It should be pointed out that for the person of ordinary skill of the art, not departing under the prerequisite of present techniques plan plot, can also make some distortion and improvement, these all belong to the application's protection domain.
