AI Technical Summary
During the use of existing round-bottom flasks, the friction between the bottle plug and the bottle mouth leads to a worse sealing effect, resulting in the volatility of the experimental samples and excessive internal air pressure, causing the bottle plug to fall off.
A snap-on round bottom flask is designed. By setting a circular top plate on the upper end of the bottle plug and a curved snap buckle on the outer edge of the upper end of the bottle mouth, combined with the design of the curved plate and the slot, the fit and stability of the bottle plug and the bottle mouth are enhanced.
By enhancing the sealing properties, the volatility of the experimental samples and contact with air are reduced, and the problem of excessive internal air pressure is prevented from falling off the bottle plug, ensuring the normal progress of the reaction.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of round-bottom flasks, in particular to a snap-on round-bottom flask. Background Art
[0002] A round-bottom flask is a transparent glass flask with a spherical bottom. It is a commonly used heating and reaction container in chemical experiments and has a wide range of uses. The mouth of a round-bottom flask is designed to be circular. During experiments, the mouth of an existing round-bottom flask is plugged with a bottle stopper to prevent the experimental sample from volatilizing. However, during use, the bottle stopper will rub against the bottle mouth. After multiple frictions, the bottle stopper and the bottle mouth will be worn, resulting in a poor sealing effect, causing the experimental sample to volatilize and increase contact with the air. Even when the reaction is intense, the internal air pressure is too high, causing the bottle stopper to fall off, affecting the normal reaction. Utility Model Content
[0003] The utility model aims to provide a snap-on round-bottom flask, which can enhance the airtightness of the round-bottom flask and the stability of the bottle stopper.
[0004] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a snap-on round-bottom flask, comprising a flask body, a bottle mouth and a bottle stopper, the flask body is a hollow sphere, the upper part of the flask body is fixedly connected to the bottle mouth, the bottle stopper is arranged on the bottle mouth, the upper outer edge of the bottle mouth is provided with an arc-shaped snap, the bottle stopper comprises a bottle stopper body, a circular top plate, an arc-shaped vertical plate and an arc-shaped plate, the bottle stopper body matches the size and shape of the bottle mouth, the circular top plate is arranged at the upper end of the bottle stopper body, the arc-shaped vertical plate is arranged at the lower end edge of the circular top plate, the arc-shaped plate is arranged at the lower end of the side of the arc-shaped vertical plate, the sum of the central angles of the arc-shaped plate, the arc-shaped vertical plate and the arc-shaped snap does not exceed 360°, and a slot is formed between the arc-shaped plate and the circular top plate, and the slot can be used for the arc-shaped snap to be inserted.
[0005] The effect of the above technical solution is: by setting a circular top plate on the upper end of the bottle stopper, the airtightness of the round-bottom flask is enhanced, the volatilization of the experimental sample and the contact with the air are reduced, and due to the mutual cooperation between the arc-shaped buckle and the groove, the fit between the circular top plate and the bottle mouth is enhanced, and the airtightness of the round-bottom flask is further improved. At the same time, it can also prevent the excessive air pressure inside the flask from causing the bottle stopper to fall off and affecting the normal reaction.
[0006] The utility model is further configured that a handle is provided at the upper end of the circular top plate.
[0007] By adopting the above technical solution, the handle provides a stable gripping point for the user, and the bottle cork can be easily removed when placed for use, while the bottle cork can be easily inserted and removed.
[0008] The utility model is further configured that the handle is spherical.
[0009] By adopting the above technical solution, the spherical handle is easy for the user to rotate to drive the arc plate to cooperate with the arc buckle, and the smooth spherical handle reduces the potential safety hazards caused by sharp edges.
[0010] The utility model is further configured that the thickness of the arc plate is H, the distance from the arc plate to the flask body is h, and h>H≥1mm is satisfied.
[0011] By adopting the above technical solution, the minimum and maximum thickness of the arc plate are guaranteed. The minimum value is guaranteed so that the arc plate has a certain strength to avoid breakage, which makes it impossible to cooperate with the arc buckle. The maximum value is guaranteed to avoid the arc plate and the card slot from being misaligned and causing the connection to fail.
[0012] The utility model is further configured that a plurality of scale lines are arranged on the outer wall of the flask body.
[0013] By adopting the above technical solution, the scale lines on the beaker body can be used to roughly estimate the volume of the liquid in the beaker, and help the user control the amount of liquid added to avoid exceeding a certain volume, thereby ensuring the accuracy and safety of the experiment.
