Description

Technical Field

[0001] This utility model relates to the field of stirring technology, specifically to an experimental stirrer. Background Technology

[0002] Experimental stirring technology is an interdisciplinary field between laboratory instruments and chemical processes, mainly involving the homogenization, dispersion, dissolution, and intensification of reaction processes of liquids, slurries, or gas-liquid mixtures.

[0003] A search of CN206810157U, a laboratory stirrer, reveals a motor whose output shaft is coaxially connected to a stainless steel stirring rod via a coupling. A disc is coaxially connected to the lower end of the stainless steel stirring rod. Six to ten sets of blades are evenly spaced around the circumference of the disc. Each set of blades includes an upper blade and a lower blade, both rectangular in shape. The upper blade is positioned on the upper side of the disc, and the lower blade on the lower side. The coupling includes an upper cover and a lower cover. The upper cover is fixedly connected to the output shaft, and the lower cover is fixedly connected to the stainless steel stirring rod. The upper and lower covers are connected by bolts. This invention utilizes a coupling to connect the stirring rod, allowing for the replacement of stainless steel stirring rods of various lengths and discs of various diameters, making the stirrer suitable for containers of various depths and inner diameters. The rectangular blades, positioned on the upper and lower sides of the disc's circumference, result in a simple structure, good mixing effect, and effective prevention of material sedimentation.

[0004] However, current small stirring devices often require manual stirring by the experimenter, which often results in liquid leakage due to unstable stirring force, thus causing waste and posing safety hazards. Utility Model Content

[0005] The purpose of this invention is to provide an experimental stirrer to address the shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a suction cup is included, a fixed plate is provided on the suction cup, one end of a first wire is connected to the suction cup near the outer ring, the other end of the first wire passes through one side of the fixed plate to the other side of the fixed plate, and a first limiting handle is provided at one end of the first wire that is not connected to the suction cup.

[0007] Furthermore, a cup body is provided on the fixed plate, a round cover is provided on the top of the cup body, a limiting member is provided on the round cover, a rubber layer is provided on the limiting member, and the limiting member corresponds to the position of the cup body.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figure 1-4 The present invention includes a suction cup 1 with a fixed plate 2. One end of a first wire 3 is connected to the suction cup 1 near the outer ring. The other end of the first wire 3 passes through one side of the fixed plate 2 to the other side. The first wire 3 is not connected to the suction cup 1 and is positioned with a first limiting handle 4. By pulling the first limiting handle 4, the first wire 3 is moved, causing one side of the suction cup 1 to be pulled, thus releasing the suction cup 1 from the table. The first limiting handle 4 is positioned away from the suction cup 1 being pulled, so that when the suction cup 1 is pulled, the finger can press against the cup body 5, preventing the cup body 5 from tipping over due to the suction cup 1 being pulled up or pulled away. At the same time, the suction cup 1 prevents the cup body 5 from tipping over if the force of pulling the second handle is too great when the liquid is being stirred. The second handle allows for quick contact and adsorption of the suction cup 1.

[0022] Preferably, a cup body 5 is provided on the fixed plate 2, and a round cover 6 is provided on the top of the cup body 5. A limiting member 7 is provided on the round cover 6, and a rubber layer is provided on the limiting member 7. The limiting member 7 corresponds to the position of the cup body 5. When it is necessary to stir the chemical product, the fixed plate 2 is fixed on the table by the suction cup 1, and then the liquid to be stirred is put into the cup body 5. The round cover 6 is then placed on the cup body 5. The setting of the limiting member 7 facilitates the fixing of the round cover 6, and the interference connection between the rubber layer and the cup body 5 prevents the cup body 5 from easily separating from the round cover 6, thus avoiding the easy leakage of the liquid.

[0023] Preferably, a torsion spring 8 is fixed on the round cover 6. The output end of the torsion spring 8 is connected to a drive shaft 9. The drive shaft 9 passes through the torsion spring 8. One end of the drive shaft 9 passes through the inside of the cup body 5. One end of several connecting rods 10 is connected to the part of the drive shaft 9 inside the cup body 5. Each of the connecting rods 10 away from the drive shaft 9 is provided with a stirring blade 11, which drives the stirring blades 11 to rotate around the drive shaft 9 as the axis. Then, the second limit handle 15 is brought close to the mounting shell 16.

[0024] Preferably, a mounting shell 16 is provided on the torsion spring 8, and one end of the drive shaft 9 passing through the top of the torsion spring 8 is located inside the mounting shell 16. The drive shaft 9 is rotatably connected to the mounting shell 16. A first limiting plate 12 and a second limiting plate 13 are sleeved on the part of the drive shaft 9 located inside the mounting shell 16. The first limiting plate 12 is rotatably connected to the mounting shell 16, and the second limiting plate 13 is rotatably connected to the torsion spring 8. One end of a second wire 14 is connected to the part of the drive shaft 9 located between the first limiting plate 12 and the second limiting plate 13. The other end of the second wire 14 passes through the outside of the mounting shell 16. A second limiting handle 15 is connected to the end of the second wire 14 located outside the mounting shell 16. Pulling the second limiting handle 15 causes the second wire 14 to be pulled, causing the drive shaft 9 to rotate, which in turn causes the first limiting plate 12 and the second limiting plate 13 to be pulled, causing the connecting rods 10 to rotate around the drive shaft 9 as the axis.

[0025] Working principle: When it is necessary to stir the chemical product, the fixing plate 2 is fixed to the table by the suction cup 1. Then, the liquid to be stirred is put into the cup body 5, and the round cover 6 is placed on the cup body 5. The setting of the limiting member 7 facilitates the fixing of the round cover 6, and the interference connection between the rubber layer and the cup body 5 prevents the cup body 5 and the round cover 6 from easily separating, avoiding easy leakage of the liquid. Then, pull the second limiting handle 15, which drives the second wire 14 to be pulled, causing the drive shaft 9 to rotate. This drives the first limiting plate 12 and the second limiting plate 13 to be pulled, causing several connecting rods 10 to rotate around the drive shaft 9 as the axis, which drives several stirring blades 11 to rotate around the drive shaft 9 as the axis. Then, bring the second limiting handle 15 close to the mounting shell 16. Under the action of the torsion spring 8, the second wire 14 is wound onto the drive shaft 9. When the torsion spring 8 moves, The drive shaft 9 is rotated, causing several stirring blades 11 to rotate in opposite directions around the drive shaft 9. Then, the action of pulling the handle is repeated, causing the liquid in the cup body 5 to be stirred by the several stirring blades 11 in a clockwise and counterclockwise rotation, which improves the stirring and mixing efficiency of the liquid. After the stirring is completed, the first limit handle 4 is pulled to move the first guide wire 3, causing one side of the suction cup 1 to be pulled, so that the suction cup 1 is released from the adsorption of the table. The first limit handle 4 is set at a position away from the suction cup 1 being pulled, so that when the suction cup 1 is pulled, the fingers can hold the cup body 5, preventing the cup body 5 from tipping over due to the suction cup 1 being pulled up or pulled away from the adsorption. At the same time, the setting of the suction cup 1 prevents the cup body 5 from tipping over if the force of pulling the second handle is too great when the liquid is stirred, and the setting of the second handle can quickly complete the contact and adsorption of the suction cup 1.

[0026] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
