Abstract
The utility model relates to a high-precision measuring cylinder with a piston. The measuring cylinder comprises a base, a main cylinder, a secondary cylinder, a capillary conduit, the piston and a reinforcing post; the main cylinder and the secondary cylinder are communicated by the capillary conduit; the piston is arranged in the secondary cylinder. The high-precision measuring cylinder with the piston is simple in structure, low in cost and simple and convenient to use, and not only has the volume measuring function of the traditional measuring cylinder, but also is higher in technical equipment stability and stronger in operability in comparison with the existing measuring cylinder, the measuring error can be effectively reduced, the measuring precision can be improved, the operation process can be simplified, the measuring time can be shortened and the measuring efficiency can be improved.
Description
Technical field
The utility model relates to a kind of graduated cylinder, relates in particular to a kind of high precision measuring cylinder with piston.
Background technology
At present, at relevant use graduated cylinder, carry out in the students practise inquiry activity of cubing, while utilizing traditional graduated cylinder to carry out cubing on the one hand, in many experiments, because traditional graduated cylinder scale division value is bigger than normal, measuring error is larger, and the density measurement and the actual value that especially in the measurement of density, due to cubing error, cause have big difference, and experimental data lacks persuasion; On the other hand for addressing the above problem, the high precision measuring cylinder consisting of major-minor cylinder that present stage is existing a kind of but not universal, connects with soft conduit between the major-minor cylinder of this graduated cylinder, and the in use movement of secondary cylinder easily causes the distortion of conduit, thereby cause the variation of catheter diameter, affect its degree of accuracy; The moving stability of the secondary cylinder of this graduated cylinder is difficult to control simultaneously, operation inconvenience.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of stability is higher, and operability is stronger, can further effectively reduce experimental error, improves a kind of high precision measuring cylinder with piston of measuring accuracy.
For addressing the above problem, a kind of high precision measuring cylinder with piston described in the utility model, is characterized in that: this graduated cylinder comprises base, is located at main cylinder and secondary cylinder on described base, described main cylinder and secondary cylinder are communicated with by capillary vessel, and described capillary vessel is provided with scale value.
In described secondary cylinder, be provided with piston.
The range of described secondary cylinder is the scale division value of described main cylinder, the volume that the volume of described secondary cylinder comprises described capillary vessel.
Between described main cylinder and secondary cylinder, be provided with reinforced column.
The utility model compared with prior art has the following advantages:.
1, because main cylinder and pair tin described in the utility model are communicated with by capillary vessel, described capillary vessel is provided with scale value, therefore, the liquid that needs to shift out in main cylinder more effectively can be moved to kapillary or secondary cylinder and presented and measure, thereby improve the degree of accuracy of measuring.
2, owing to being provided with piston in secondary cylinder described in the utility model, therefore, can realize flowing of liquid between major-minor cylinder by pulling or promoting to adjust piston, avoid to greatest extent, due to error mobile and that the secondary cylinder of adjustment position produces, having heightened stability and the operability of experimental facilities simultaneously.
3, the range due to secondary cylinder described in the utility model is the scale division value of described main cylinder, and therefore the volume that the volume of described secondary cylinder comprises described capillary vessel, can further improve confidence level and the degree of accuracy measured.
4, owing to being provided with reinforced column between main cylinder described in the utility model and secondary cylinder, therefore, can effectively improve its strength and stability.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1-base 2-main cylinder 3-secondary cylinder, 4-capillary vessel, 5-piston, 6-reinforced column.
