Abstract
The utility model provides a piston type measuring cylinder which is convenient to use. The piston type measuring cylinder comprises an outer pipe with marks and an inner pipe with marks. One end of the inner pipe is connected with a piston arranged in the outer pipe, a through hole which is used for communicating the inner pipe and the outer pipe is formed in the piston, a handle is arranged at the other end of the inner pipe, and the handle is connected with a piston which is arranged in the inner pipe. According to the piston type measuring cylinder, the outer pipe and the inner pipe are combined to form a two-measuring-cylinder structure, measuring accuracy can be adjusted, liquid which is accurate in measurement can be obtained through one measurement, measuring operation is simplified, and experiment efficiency is improved.
Description
Technical field
The utility model relates to the graduated cylinder that uses in large-scale universities and colleges, the R﹠D institution laboratory, particularly a kind of piston type graduated cylinder.
Background technology
The used graduated cylinder specification in laboratory is respectively 5ml, 10ml, 50ml, 100ml, 200ml, 250ml, 500ml, 1000ml and 2000ml etc. now, the minimum division value of these graduated cylinders is all fixed, the precision of measuring can't be adjusted, and the specification of graduated cylinder is big more, the also corresponding increase of its minimum division value, measure the liquid of large volume if desired accurately, need to use the graduated cylinder of different size, operate also very loaded down with trivial details.
The utility model content
The purpose of this utility model is to provide a kind of piston type graduated cylinder easy to use.
For achieving the above object, the utility model has adopted following technical scheme:
Comprise the outer tube and the interior pipe that have scale, one end of described interior pipe links to each other with the piston in being arranged at outer tube, offer the through hole that is used to be communicated with interior pipe and outer tube on the piston in the outer tube, the other end of interior pipe is provided with handle, and the handle piston interior with being arranged at interior pipe links to each other.
Pipe box is located in the outer tube in described.
Described outer tube is provided with triangle bracket.
Piston type graduated cylinder described in the utility model is formed two graduated cylinder structures by outer tube and interior pipe, and measuring accuracy is adjustable, once measures just can obtain to measure accurate liquid, has simplified and has measured operation, has improved conventional efficient.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: outer tube 1, interior pipe 2, piston 3, through hole 4, handle 5, triangle bracket 6.
Embodiment
Below in conjunction with drawings and Examples utility model is described further.
Referring to Fig. 1, the utility model comprises outer tube 1 and the interior pipe 2 that has scale, pipe 2 is sheathed in the outer tube 1 in described, a pipe end of 2 links to each other with piston 3 in being arranged at outer tube 1 in described, offer the through hole 4 of pipe 2 and outer tube 1 in being used to be communicated with on the piston 3 in the outer tube, the other end of interior pipe 2 is provided with handle 5, handle 5 be arranged in piston 3 in the pipe 2 link to each other, described outer tube 1 is provided with triangle bracket 6, and triangle bracket can make stable, the safe placement of piston type graduated cylinder.
During use, adjust the liquid volume that outer tube is measured with the piston in the outer tube 13, adjust the liquid volume that interior pipe is measured with interior pipe 2 inner carriers 3, the number reading method and the vernier caliper of this graduated cylinder are similar, the scale reading of pipe in the scale reading that liquid volume equals outer tube adds, behind the constant volume, the liquid in the interior pipe is advanced outer tube with the piston in the interior pipe, pour out from outer tube then.
Embodiment
A kind of safe in utilization, convenient, piston type graduated cylinder that accuracy is high, comprise interior pipe, outer tube, inner core rubber handle and triangle of safety support, outer tube is a siphunculus, in order to measure the liquid of larger volume, interior pipe is one to have the injection-tube of the piston that can move up and down in outer tube, in order to measure the higher liquid of precision, that utilizes the inner and outer pipe inner carrier upper and lowerly draws high the adjustment that realizes measuring volume, add liquid then and realize measuring of liquid in graduated cylinder, the constant volume mode is that the upper and lower of interior pipe inner carrier drawn high.
