Description
Technical Field
The utility model relates to a chemistry experiment household utensils technical field especially relates to a graduated flask of liquid is got to quick simple and convenient ration.
Background
In chemical analysis experiments, measuring cylinders are often used, and particularly in actual production-type detection, a large volume of liquid solvent or water sample needs to be quantitatively measured in batches for analysis of some chemical projects. When a common measuring cylinder is used for sampling, the amount of the liquid to be removed is difficult to grasp manually, and the accuracy of the sampling volume is usually adjusted by repeatedly adding and pouring; once the operation is carried out in a large batch, the working efficiency is seriously reduced, and the attention, the energy and the physical strength of experimenters are greatly consumed. Although the existing handheld pipettor is rapid and convenient to sample, the existing handheld pipettor is not suitable for moving and taking liquid with the volume of more than 10mL and operated in batches, and the cost of the handheld pipettor is high.
Disclosure of Invention
The utility model aims to solve the technical problem that a graduated flask of liquid is got to quick simple and convenient ration is provided, and traditional chemistry experiment is overcome to this graduated flask in move the defect of liquid, realizes that the ration is moved the liquid fast portably, effectively improves work efficiency, reduces intensity of labour, ensures the accuracy of experiment, and this graduated flask preparation is convenient, low cost.
For solving the technical problem, the utility model discloses a graduated flask of liquid is got to quick simple and convenient ration includes the graduated flask body, graduated flask body lateral wall is equipped with the capacity scale from the top down, still includes base, piston and lift adjustment pole, graduated flask body bottom is opened there is the through-hole, the piston is located this internal and the bottom that is located the graduated flask body under the effect of dead weight under free state of graduated flask, lift adjustment pole is located perpendicularly the base top surface, the graduated flask body seat in the base top surface, the lift adjustment pole penetrates the through-hole and the top embedding of graduated flask body bottom the piston.
Further, the lifting adjustment rod is a threaded rod and is threadedly connected with the base.
Because the utility model discloses the graduated flask of liquid has been adopted to quick simple and convenient ration, this graduated flask includes the graduated flask body that is equipped with the capacity scale from the top down at the lateral wall promptly, a pedestal, piston and lift adjusting rod, graduated flask body bottom is opened there is the through-hole, this internal and the bottom that lies in the graduated flask body under the effect of dead weight of free state under of piston locating graduated flask, base top surface is located perpendicularly to the lift adjusting rod, the graduated flask body is located base top surface, the lift adjusting rod penetrates the through-hole and the top embedding piston of graduated flask body bottom. The measuring cylinder overcomes the defect of liquid transfer in the traditional chemical experiment, realizes quantitative liquid transfer quickly, simply and conveniently, effectively improves the working efficiency, reduces the labor intensity, ensures the accuracy of the experiment, and is convenient to manufacture and low in cost.
Drawings
The invention will be described in further detail with reference to the following drawings and embodiments:
FIG. 1 is a schematic view of a measuring cylinder for rapid, simple and quantitative liquid extraction;
FIG. 2 is a schematic view of a liquid taking state by using the measuring cylinder;
FIG. 3 is a schematic view of the piston sinking into the bottom of the measuring cylinder body after the measuring cylinder is used for taking liquid.
Detailed Description
Embodiment is shown in fig. 1, the utility model discloses a graduated flask of liquid is got to quick simple and convenient ration includes graduated flask body 1, graduated flask body 1 lateral wall is equipped with the capacity scale from the top down, still includes base 2, piston 3 and lift adjusting rod 4, open graduated flask body 1 bottom has the through-hole, piston 3 locates in graduated flask body 1 and be located graduated flask body 1's bottom under the effect of dead weight under free state, lift adjusting rod 4 is located perpendicularly base 2 top surface, graduated flask body 1 sit in base 2 top surface, lift adjusting rod 4 penetrates the through-hole and the top embedding of graduated flask body 1 bottom piston 3.
Preferably, the lifting adjustment rod 4 is a threaded rod and is in threaded connection with the base 2.
The lifting adjusting rod 4 in the measuring cylinder is not limited to a screw rod, and can be a component such as a spring and the like which can adjust the lifting of the piston, and the lifting of the piston can be adjusted by adopting a proper mechanism such as a pull rope and the like to control the stretching amount of the spring.
The piston in this graduated flask can select glass material or plastics material embedding metal pouring weight for use in order to improve its dead weight, and the graduated flask body is gone up along for capacity scale zero point, and the number of graduations from top to bottom increases gradually. When the measuring cylinder body is placed on the base, the bottom surface of the measuring cylinder is folded with the top surface of the base, the piston is positioned at the bottom of the measuring cylinder body, and the scale indicated by the upper edge of the piston is the total volume of the measuring cylinder. When carrying out the lift adjustment to the lift adjustment pole through the base, the drive piston goes up and down at this internal lift of graduated flask to change the piston at this internal position of graduated flask, realize the regulation of graduated flask capacity, with the demand that adapts to different sample volumes.
As shown in fig. 2 and 3, during sampling, the piston 3 is adjusted to a sampling volume scale through the lifting adjusting rod 4 according to the sampling volume, the measuring cylinder body 1 is placed into the water tank along with the base 2, the measuring cylinder body 1 is filled with the sampling liquid, the excess liquid overflows along the upper edge of the measuring cylinder body 1, so that the liquid with the required volume is accurately obtained, the measuring cylinder body 1 is taken up during liquid transfer, at the moment, the piston 3 inside the measuring cylinder body 1 sinks to the bottom of the measuring cylinder body 1 due to self weight, the base 2 sinks along with the piston 3, the liquid level is lower than the upper edge of the measuring cylinder body 1 along with the liquid level, and liquid does not spill even if the measuring cylinder body 1 vibrates in the moving and liquid transfer processes, so that continuous and rapid quantitative sampling can be realized. The measuring cylinder has the advantages of simple structure, low cost, simple and quick operation and easy cleaning.
