Description

Technical Field

[0001] The utility model relates to a laboratory anti-dumping round-bottom flask base, belonging to the technical field of flask bases. 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. Compared with a flat-bottom flask, the bottom of a round-bottom flask is evenly thick and has no edges and corners, which is suitable for long-term heating and has a wide range of uses. When it is generally used or placed, because the bottom of a round-bottom flask is spherical, it cannot be placed directly on the table like a flat-bottom flask, and needs to be placed using a flask stand or flask base.

[0003] Most of the existing flask bases are metal frames. Because the edge of the metal frame is thin, there is only one ring at the force point supporting the flask. Therefore, if the flask is accidentally touched, it will cause the flask to tip over. The stability is poor and the defects are obvious. Improvement is urgently needed. Therefore, a laboratory anti-tipping round-bottom flask base is needed for people to use. Utility Model Content

[0004] The utility model aims to provide a laboratory anti-tipping round-bottom flask base. After the flask is placed in the flask placement groove, the spacing between the fastening clamps can be adjusted by adjusting the structure such as the screw rod, so that the diameter of the flask can be clamped and fixed, thereby ensuring the stability of the flask placement and preventing it from tipping over during use. Moreover, after the flask is used, it is convenient to quickly cool it down through the operation of the heat dissipation fan, and it is easy to use, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A laboratory anti-tipping round-bottom flask base comprises a flask base, the bottom end surface of the flask base is fixedly connected with a base leg, and the base legs are evenly distributed at the four corner positions of the bottom of the flask base, a flask placement groove is provided on the inner side of the flask placement groove, an exhaust filter is provided on the inner side of the flask base, an air intake filter is fixedly connected on the inner side of the flask base, a mounting groove is provided on the inner side of the flask base, a heat dissipation fan is fixedly connected on the inner side of the mounting groove, and a fixed leg is fixedly connected to the top surface of the flask base, the number of the fixed legs is four, and the other end of each of the fixed legs is fixedly connected to a flask fixing seat, and a fixing groove is provided on the inner side of the flask fixing seat.

[0007] Furthermore, the heat dissipation fans are arranged to be tilted upward, and there are four heat dissipation fans distributed in a ring array.

[0008] Furthermore, an adjusting groove is provided on the inner side of the flask fixing seat, an adjusting screw rod is rotatably connected to the inner side of the adjusting groove, and one end of the adjusting screw rod is fixedly connected to an adjusting turntable.

[0009] Furthermore, the adjusting screw rod is a bidirectional screw rod, and the outer side of the adjusting screw rod is spirally connected to an adjusting slider.

[0010] Furthermore, one side of the adjusting slider is fixedly connected to an adjusting support plate, one side of the adjusting support plate is fixedly connected to a fastening clamping plate, and the fastening clamping plate is arranged in an arc shape.

[0011] Furthermore, an anti-slip groove is provided on the inner side of the flask fixing seat, and the adjustment support plate is slidably connected to the flask fixing seat through the anti-slip groove.

[0012] The beneficial effects of the utility model are:

[0013] The flask can be placed in the flask placing groove and the bottle diameter can be placed in the fixing groove by adjusting the screw rod, and then the adjusting dial can be turned to move the adjusting slider in the opposite direction, and the slider drives the adjusting support plate and the fixing clamping plate to move in the opposite direction, so as to facilitate the clamping and fixing of the flask. After the flask is used, the heat dissipation fan can be used to blow air, which can accelerate the cooling and heat dissipation of the flask, and the adjusting dial can be reversed later to move the fixing clamping plate away from the flask so as to remove the flask. In summary, when the utility model is in use, after the flask is placed in the flask placing groove, the spacing between the fixing clamping plates can be adjusted by adjusting the screw rod and other structures, so that the bottle diameter of the flask can be clamped and fixed, ensuring the stability of the flask placement and preventing it from tipping over during use. Moreover, after the flask is used, it is convenient to quickly cool it down through the operation of the heat dissipation fan, which is convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
