Description

Single erlenmeyer flask fixed suction cup for chemistry experiments

Technical Field

The utility model belongs to the technical field of chemistry experiment appurtenance, concretely relates to fixed sucking disc of single erlenmeyer flask when relevant laboratories such as chemistry are experimental.

Background

In chemical experiments, the conical flask is a common solution container, and prepared solution or filtered solution needs to be filled into the conical flask, placed on a laboratory bench and then subjected to the next operation. In the actual operation process, the erlenmeyer flask places the in-process that the laboratory bench waited for experimental operation on next step, and the error of experimenter often appears and hits the erlenmeyer flask and lead to solution to flow out, causes the experiment merit in earlier stage to lack one and be short of one and weak point, pushes away to heavily coming, extravagant experimenter time, if corrosive solution simultaneously, can cause the harm to other article, data on experimenter or the laboratory bench. Chinese patent CN 204021521U provides a flask rack which occupies a large area on the test bed and is not suitable for single flask operation. The erlenmeyer flask frame or the erlenmeyer flask frame all belong to the erlenmeyer flask frame in the biological incubator among other common patents, or the erlenmeyer flask frame of drying after the erlenmeyer flask washs of being convenient for, or the erlenmeyer flask inclined stand of being convenient for single aseptic technique, all are not applicable to the fixed of single erlenmeyer flask in the chemical experiment.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a be convenient for fix single erlenmeyer flask in chemical experiment process, make the erlenmeyer flask be difficult for hitting down, small and exquisite convenient erlenmeyer flask fixed suction cup.

The utility model discloses an above-mentioned technical problem is solved to following technical scheme:

the utility model provides a single erlenmeyer flask fixed suction cup for chemistry experiments, includes sucking disc and retainer plate and constitutes, its characterized in that, the sucking disc convex surface links to each other with the retainer plate bottom.

The sucking disc is the uplift circular, covers the concave surface in smooth laboratory bench, presses sucking disc convex surface top, also is the retainer plate bottom with the hand, arranges the air in the concave surface, can fix fixed suction cup at the experiment mesa.

The whole shape of the fixed ring is similar to that of the bottom of the conical flask, the diameter of the lower part is large, and the diameter of the upper part is small. Three grooves are arranged on the fixed ring, and the positions of the three grooves are distributed on the fixed ring in a regular triangle manner.

The utility model discloses by acid and alkali-resistance stereoplasm silica gel or silica gel preparation, the retainer plate has certain elasticity very much, can squeeze the retainer plate border at the in-process of the erlenmeyer flask of packing into or pull open, and the erlenmeyer flask is packed into the back and is found the horse and resume to the normal position and wrap up in tight erlenmeyer flask.

The size of the utility model, including the diameter of the sucker, the bottom diameter of the fixing ring, the height of the fixing ring, etc., can be determined according to conical bottles with different sizes.

The utility model is designed according to the conical flask, but can also be used for fixing the same-size triangular flask, the beaker and other equipment. The utility model discloses also can design into the hemisphere with the retainer plate to be applicable to the round flask.

The utility model discloses simple structure, occupation space is little, convenient operation can fix the erlenmeyer flask again, is difficult for hitting down.

Drawings

FIG. 1 is a schematic overall view of the present invention (fixed on the surface of an experiment table);

FIG. 2 is a schematic side view of the present invention (not fixed on the table top);

in the figure, 1 is a sucker and 2 is a fixing ring.

Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings and examples. It should be understood that the preferred embodiments described herein are for purposes of illustration and explanation only and are not intended to limit the invention. Based on the embodiments in the present invention, other embodiments about obtained under the premise that creative work is not done by ordinary skilled in the art all belong to the protection scope of the present invention.

A conical bottle fixing sucker for chemical experiments comprises a sucker 1 and a fixing ring 2.

The sucker 1 is slightly raised and round, and the top of the sucker 1 is connected with the bottom of the fixing ring 2;

the diameter of the bottom of the fixing ring 2 is larger than that of the upper part, so that the whole fixing ring 2 is similar to the shape of the bottom of the conical flask.

Three grooves are formed in the fixing ring 2, so that the fixing ring 2 can be conveniently filled in a conical bottle.

The three grooves are distributed in a regular triangle shape.

Use the utility model discloses the time, at present place smooth experiment mesa suitable position downwards with 1 concave surface of sucking disc in, press the retainer plate 2 bottom with the hand, arrange the air in the sucking disc 1 to the greatest extent, can with the utility model discloses be fixed in the experiment mesa, then break off retainer plate 2 with the hand off with the fingers and thumb, put into retainer plate 2 with the erlenmeyer flask, loose hand retainer plate 2 wraps up the erlenmeyer flask promptly.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

Claims (1)

1. A single conical flask fixing sucker for chemical experiments comprises a sucker and a fixing ring, and is characterized in that the convex surface of the sucker is connected with the bottom of the fixing ring, and the sucker is in a raised circular shape; the whole fixed ring is similar to the bottom of the conical flask in shape, the diameter of the lower part is large, and the diameter of the upper part is small; three grooves are formed in the fixed ring, and the positions of the three grooves are distributed on the fixed ring in a regular triangle manner; the material is acid and alkali resistant hard silica gel or silica gel.
