[0002] A magnetic stirrer is a laboratory instrument used for liquid mixing. It is mainly used for stirring or simultaneously heating and stirring low-viscosity liquids or solid-liquid mixtures. A magnetic stirrer is an instrument that utilizes the property of like poles repelling each other in magnetic materials. It drives the magnetic stirrer to rotate by continuously changing the polarity of the two ends of the base. The rotation of the magnetic stirrer then drives the sample to rotate, so that the sample is evenly mixed. In conjunction with a heating temperature control system, the sample temperature can be heated and controlled according to specific experimental requirements, maintaining the temperature conditions required by the experimental conditions, and ensuring that the liquid mixing meets the experimental requirements.

[0003] During the use of the existing magnetic stirrer, the beaker placed on the stirring table is easily offset due to the stirring of the solution inside, and in severe cases it may cause tilting, thereby affecting the safety of the experiment. Based on this, a magnetic stirrer with an anti-dumping function is provided. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 4 In an embodiment of the utility model, a magnetic stirrer with an anti-dumping function includes a magnetic stirrer 1 composed of a base shell 101 and a base platform 102, the base platform 102 is fixed to the top of the base shell 101, the top of the base shell 101 is located on the outside of the base platform 102 and a protective component 2 is provided, and a locking component 3 is provided on the outside of the protective component 2;

[0028] The protection component 2 is used to limit the position of containers of different diameters placed on the top of the base platform 102 to prevent the containers from shifting; the locking component 3 is used to lock the protection component 2 to achieve the fixing of the protection component 2 on the container limit state;

[0029] The protection assembly 2 includes a fixed ring seat 201, a straight notch 202, a transmission gear 203, a connecting arm 204, and a roller 205;

[0030] The fixed ring seat 201 is fixed to the top of the base housing 101 and is located outside the base platform 102. The straight slot 202 is opened outside the fixed ring seat 201 and passes through the inside of the fixed ring seat 201.

[0031] The transmission gear 203 is rotatably connected to the top of the inner side of the fixed ring seat 201, the connecting arm 204 is fixedly connected to one side of the transmission gear 203 and is located on the inner side of the fixed ring seat 201, and the roller 205 is rotatably connected to the inner side of the connecting arm 204 away from the transmission gear 203;

[0032] There are multiple straight slots 202, transmission gears 203, connecting arms 204, and rollers 205, which are distributed in a ring shape with the base 102 as the center. The synchronous rotation of multiple connecting arms 204 can achieve the limitation of containers with different diameters.

[0033] The locking assembly 3 includes a lifting collar 301, a top limiting ring 302, an annular tooth groove 303, a threaded hole 304, a knob 305, and a locking bolt 306;

[0034] The lifting ring 301 is vertically slidably sleeved on the outside of the fixed ring seat 201, the top limit ring 302 is fixed on the top of the lifting ring 301, and the annular tooth groove 303 is integrally formed on the inside of the lifting ring 301 and multiple teeth are evenly arranged along the vertical direction;

[0035] The plurality of transmission gears 203 protrude to the outside of the fixed ring seat 201 and mesh with the annular tooth groove 303 to achieve synchronous rotation of the plurality of transmission gears 203;

[0036] The threaded hole 304 is formed at one end of the outer side of the lifting collar 301 and passes through the inner side of the lifting collar 301. The locking bolt 306 is fixed to one end of the knob 305, and the locking bolt 306 is threadedly connected to the inner side of the threaded hole 304.

[0037] The locking bolt 306 passes through the threaded hole 304 and fits tightly against the outer side of the fixing ring seat 201 to achieve relative fixation of the lifting ring 301 and the fixing ring seat 201 .

[0038] In this embodiment: It should be noted that: this solution only improves the structure of the top of the base housing 101, so the internal structure of the magnetic stirrer 1 is not described in detail;

[0039] When the magnetic stirrer 1 is in use, the locking bolt 306 is first loosened by the knob 305 to release the locking bolt 306 from the tight fit with the fixed ring seat 201, and the relative fixation between the lifting ring 301 and the fixed ring seat 201 is released.

[0040] Then, the container containing the solution to be mixed is placed on the top of the base 102. During this process, the container will contact with the multiple rollers 205 and give them an extrusion force. The rollers 205 transmit the extrusion force to the connecting arm 204 and the transmission gear 203. At this time, the connecting arm 204 and the transmission gear 203 rotate around the rotation point of the transmission gear 203. The multiple rotating arms 204 rotate downward to expand the distribution track diameter of the multiple rollers 205. Finally, the distribution track of the multiple rollers 205 matches the outer diameter of the container. At this time, the container easily passes through the middle area of ​​the multiple rollers 205 and is placed on the top of the base 102, and the multiple rollers 205 are attached to the outside of the container.

[0041] At the same time, when the transmission gear 203 rotates, the lifting ring 301 can be pushed upward. When the container is placed, the locking bolt 306 is tightened by the knob 305 so that the locking bolt 306 is closely attached to the outer side of the fixed ring seat 201. In this way, the height of the lifting ring 301 is fixed. That is, at this time, the transmission gear 203 and the rotating arm 204 cannot rotate, and the position of the roller 205 remains fixed. In this way, the container is clamped and fixed in the middle of the multiple rollers 205, effectively avoiding the deviation in the later stage.

[0042] It should be noted that: during the secondary operation, if the container specifications are the same as the first container, there is no need to loosen the locking bolt 306. If the container diameter is different during the secondary operation, it is necessary to loosen the locking bolt 306 before placing the container.

[0043] Please refer to Figures 1 to 3 The overall weight of the lifting ring 301 and the top limiting ring 302 is greater than the overall weight of the multiple sets of transmission gears 203 , the connecting arm 204 , and the roller 205 .

[0044] In this embodiment: through this structure, after loosening the locking bolt 306 and when there is no container among the multiple rollers 205, the lifting ring 301 can move downward under the action of its own gravity, so that the multiple connecting arms 204 rotate to return to the initial state, which is convenient for limiting operations on containers of other diameters.

[0045] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
