Description

Drainage device is emptyd to volumetric flask solution

Technical Field

The utility model relates to a drainage device for pouring a solution in a volumetric flask.

Background

The chemical laboratory often uses volumetric flask of different specifications when doing the experiment, and the thin neck of volumetric flask easily forms solution surface tension, and it is difficult for flowing out or liquid outflow to carry out the liquid and topple over, and especially for the small-size volumetric flask liquid when 2ml volumetric flask forms more easily above-mentioned phenomenon.

SUMMERY OF THE UTILITY MODEL

The present invention aims to solve the above technical problem at least to some extent. Therefore, the utility model provides a volumetric flask solution pouring drainage device, which aims to solve the problem that the volumetric flask in a laboratory is difficult to flow out due to surface tension when the volumetric flask pours liquid.

In order to achieve the purpose, the utility model adopts the following technical scheme:

a volumetric flask solution pouring drainage device comprising:

the volumetric flask has a slender bottleneck and a bottleneck at the top end;

the sleeve is of a truncated cone-shaped tubular structure with a large lower end and a small upper end, the large end is provided with an opening and a bayonet which is matched with the mouth of the volumetric flask, the large end is downwards clamped on the mouth of the volumetric flask through the bayonet, the small end is provided with a drainage nozzle which is exposed along the length direction of the sleeve, a sunken drainage groove is formed in the sleeve along the whole length of the sleeve along the drainage nozzle, the sleeve further comprises a drainage tube, the drainage tube is arranged along the drainage groove, is embedded in the drainage groove, keeps a gap between the drainage tube and the drainage groove, is exposed downwards and extends into the volumetric flask, and vertically keeps a gap between the drainage tube and the bottom of the volumetric flask.

The utility model also has the structural characteristics that:

the inner wall of the sleeve is sunken corresponding to the drainage groove to form the drainage groove, and the drainage groove is a rectangular long groove.

The drainage tube is a plastic tube.

The drainage tube is a glass tube.

The drainage nozzle is a sharp-nozzle-shaped structure with the pointed end outwards.

The sleeve is made of transparent plastic, and scales arranged along the whole length of the cylinder body are arranged on the outer wall of the sleeve corresponding to the drainage groove.

Compared with the prior art, the utility model has the beneficial effects that:

according to the utility model, the sleeve is clamped on the bottle mouth of the volumetric flask, and the solution in the volumetric flask can be poured and drained more easily by virtue of the drainage tube, the drainage groove and the drainage nozzle which are arranged on the sleeve, so that the problem that the liquid is difficult to flow out or flows out due to surface tension when the liquid is poured in the existing laboratory volumetric flask is solved.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 3, the volumetric flask solution pouring drainage device of the present embodiment includes:

the volumetric flask 1 has a slender bottleneck and a bottleneck at the top end;

sleeve 2, be big-end-up's round platform shape tubular structure down, the main aspects opening is equipped with the bayonet socket 3 of adaptation in the 1 bottleneck of volumetric flask, clamp on 1 bottleneck of volumetric flask down with the main aspects through bayonet socket 3, the tip is equipped with along the exerted drainage mouth 5 of section of thick bamboo length direction, set up sunken drainage groove 4 along the barrel overall length along drainage mouth 5 in the section of thick bamboo, still include drainage tube 6, drainage tube 6 arranges along drainage groove 4, inlay the dress in drainage groove 4, and remain the interval between the drainage groove 4, drainage tube 6 exposes down and stretches into in volumetric flask 1, and the vertical clearance that leaves between the bottom of the bottle of volumetric flask 1.

In the specific implementation:

the inner wall of the sleeve 2 is sunken to form a drainage groove 4 corresponding to the drainage groove 4, and the drainage groove 4 is a rectangular long groove.

The drainage tube 6 is a plastic tube.

The drainage tube 6 is a glass tube.

The drainage nozzle 5 is a sharp-nozzle-shaped structure with the pointed end facing outwards.

The sleeve 2 is transparent plastic material, and the position corresponding to drainage groove 4 on the outer wall is equipped with along the scale 7 that the barrel full length was arranged.

The operation mode is as follows:

the sleeve 2 is clamped on the volumetric flask 1 with the large end facing downwards and vertically, the drainage tube 6 is hung downwards in the volumetric flask 1 and extends to the bottom of the flask, the surface tension of the liquid in the volumetric flask 1 is damaged to a certain extent due to the drainage tube 6, so that the liquid can flow out more easily, and the problem of the original liquid outflow can be solved due to the surrounding of the sleeve 2;
