Abstract
The utility model discloses an anti-falling measuring cylinder. The anti-falling measuring cylinder comprises a straight cylinder, wherein the lower part of the straight cylinder is connected with a hemispherical accommodating cavity which is communicated with the straight cylinder; a base is connected below the accommodating cavity; a suction disk is arranged below the base; the diameter of the accommodating cavity is 6 times that of the straight cylinder. According to the anti-falling measuring cylinder, the lower part of the straight cylinder is connected with the hemispherical accommodating cavity, and the diameter of the accommodating cavity is 6 times that of the straight cylinder, so that the height of the measuring cylinder can be remarkably reduced under the same volume; therefore, the stability is enhanced, and the measuring cylinder is prevented from being knocking down. The diameter of the straight cylinder is smaller, so that the precision of the measuring cylinder is higher; the suction disk is arranged on the base, so that the stability can be further enhanced.
Description
Technical field
The invention belongs to experiment equipment field, be specifically related to a kind of anti-down graduated cylinder.
Background technology
Graduated cylinder is a kind of utensil for metering liquid volume, generally adopts glass to make growth tubular.What capacity will be done more greatly is higher thicker.So just there are three problems: the one, easily knock damage over, the 2nd, reading accuracy is poor.
Summary of the invention
The object of the invention is to provide a kind of anti-down graduated cylinder, solves existing graduated cylinder and easily knocks damage and the poor problem of precision over.
Technical scheme of the present invention is: a kind of anti-down graduated cylinder, comprise straight tube, and described straight tube bottom is connected with the hemispheric cavity volume being communicated with straight tube, under cavity volume, is connected with base, and described base is arranged with sucker, and the diameter of described cavity volume is 6 times of straight tube diameter.
The present invention compared with prior art tool has the following advantages:
The present invention by connecting hemispheric cavity volume under straight tube, and the diameter of described cavity volume is 6 times of straight tube diameter, 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, on described base, is provided with sucker, can further strengthen stability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, Reference numeral is: 1-straight tube, 2-cavity volume, 3-base, 4-sucker.
Embodiment
As shown in Figure 1, a kind of anti-down graduated cylinder, comprises straight tube 1, and described straight tube 1 bottom is connected with the hemispheric cavity volume 2 being communicated with straight tube 1.Cavity volume is connected with base 32 times, and described base 3 is arranged with sucker 4, and the diameter of described cavity volume 2 is 6 times of straight tube 1 diameter.
The present invention is by connecting hemispheric cavity volume 2 for 1 time in straight tube, and the diameter of described cavity volume 2 is 6 times of straight tube 1 diameter, 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, on described base 3, is provided with sucker 4, can further strengthen stability.
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.
