Abstract
The invention discloses a measuring cylinder with variable capacity. The measuring cylinder comprises a straight cylinder, the lower portion of the straight cylinder is sleeved with a soft bag body, the straight cylinder is communicated with the bag body, and the bag body is composed of a neck portion, an upper plate, a flexible connecting portion and a base plate. The bag body is integrally made of polytetrafluoroethylene materials, the upper plate and the base plate are both hard plates and are the same in shape, and the area of a horizontal section at any position of the flexible connecting portion is no larger than the area of the base plate. According to the measuring cylinder with the variable capacity, due to the fact that the lower portion of the straight cylinder is sleeved with the soft bag body, when the measuring cylinder is lifted and liquid is added into the measuring cylinder, the volume of the liquid is equal to the sum of the volume of the bag body and the volume of the straight cylinder; when the liquid adding quantity is small, the measuring cylinder is pressed on a tabletop, liquid is added into the measuring cylinder, at the moment, the bag body is not filled with water, and the volume of the liquid is equal to the volume of the straight cylinder. The bag body is made of the polytetrafluoroethylene materials, and has the effects of acid, alkali and corrosion resistance. The measuring cylinder with the variable capacity can measure a large proportion of liquid and has the advantages of being simple in structure, convenient to use and practical.
Description
Technical field
The invention belongs to experiment equipment field, be specifically related to a kind of graduated cylinder of volume-variable.
Background technology
Graduated cylinder is a kind of utensil for metering liquid volume, generally adopts glass to make growth tubular.Existing graduated cylinder capacity is all fixed, and in the time will measuring the liquid that is greater than existing graduated cylinder volume, with regard to changing graduated cylinder or divide, measures several times, seems inconvenient.
Summary of the invention
The object of the invention is to provide a kind of graduated cylinder of volume-variable, solves the immutable problem of existing graduated cylinder volume.
Technical scheme of the present invention is: a kind of graduated cylinder of volume-variable, comprise straight tube, described straight tube bottom cover has a soft bag, described straight tube is communicated with bag, described bag by neck, upper plate, flexibly connect portion and base plate forms, described bag integral body is teflon material, and upper plate is hard plate with base plate and shape is identical, described in flexibly connect the horizontal section of portion optional position area be not more than the area of base plate.
The present invention compared with prior art tool has the following advantages:
The present invention is by the soft bag of bottom socket in straight tube, when graduated cylinder is mentioned to liquid feeding, the volume of liquid is the volume that the volume of bag adds straight tube, when getting liquid measure when less, by graduated cylinder, by carry out liquid feeding on table top, now bag just can not fill water, the volume of liquid is exactly the volume of straight tube, bag adopts teflon material, has the corrosion resistant effect of acid-fast alkali-proof, can measure most liquid.Upper plate is hard plate with base plate and shape is identical, described in flexibly connect the horizontal section of portion optional position area be not more than the area of base plate.Can guarantee that bag can not enter liquid substantially when compression bag.There is simple, the convenient and practical feature of knot.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, Reference numeral is: 1-straight tube, 2-bag.
Embodiment
As shown in Figure 1, a kind of graduated cylinder of volume-variable, comprises straight tube 1, and described straight tube 1 bottom cover has a soft bag 2, and described straight tube 1 is communicated with bag 2.Described bag 2 by neck, upper plate, flexibly connect portion and base plate forms, neck is enclosed within the lower end of straight tube 1.Described bag 2 integral body are teflon material, and upper plate is hard plate with base plate and shape is identical, described in flexibly connect the horizontal section of portion optional position area be not more than the area of base plate.When compression is during bag 2, under the effect of upper plate and base plate, can guarantee that 2 li of bags substantially can feed liquor body.
The present invention is by the soft bag 2 of bottom socket in straight tube 1, when graduated cylinder is mentioned to liquid feeding, the volume of liquid is the volume that the volume of bag 2 adds straight tube 1, when getting liquid measure when less, by graduated cylinder, by carry out liquid feeding on table top, now bag 2 just can not fill water, the volume of liquid is exactly the volume of straight tube 1, bag 2 adopts teflon material, has the corrosion resistant effect of acid-fast alkali-proof, can measure most liquid.There is simple, the convenient and practical feature of knot.
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.
Claims (1)
1. the graduated cylinder of a volume-variable, comprise straight tube, it is characterized in that: described straight tube bottom cover has a soft bag, described straight tube is communicated with bag, described bag by neck, upper plate, flexibly connect portion and base plate forms, described bag integral body is teflon material, and upper plate is hard plate with base plate and shape is identical, described in flexibly connect the horizontal section of portion optional position area be not more than the area of base plate.
