Description

TECHNICAL FIELD

[0001] The utility model belongs to magnetic stirrer technical field, especially the inorganic heavy metal detection ware magnetic stirrer with positioning mechanism. BACKGROUND

[0002] Inorganic heavy metal detection is the detection mode for determining the content of inorganic heavy metal elements such as mercury, cadmium, lead, etc. in various samples such as soil, water, food, etc. At present, magnetic stirrers are often used to assist in detection during inorganic heavy metal detection. The main reason for using magnetic stirrers for auxiliary detection is that during the detection process, it can fully mix the sample and reagent. For heavy metal samples that may not be evenly distributed, stirring can ensure complete detection reaction, improve accuracy, and when the reagent is added, it can quickly disperse the reagent, speed up the reaction speed, shorten the detection time, and at the same time, when cooperating with the heating device for detection, it can also make the heat evenly distributed, avoid local overheating or uneven reaction, and improve the accuracy and reproducibility of the detection results.

[0003] The Chinese patent with publication number "CN209005657U" discloses a magnetic stirrer, which includes a main body, a tray detachably connected to the main body, a connecting mechanism provided on the tray and connecting the tray and the main body, a plurality of insertion holes with their axis along the thickness direction of the tray, an inner surface of the tray in contact with the main body, and an outer surface of the tray away from the main body, and a limiting rod inserted into the insertion hole. The utility model solves the problem that the beaker containing the sample on the magnetic stirrer is easy to tip over when the magnetic stirrer is working.

[0004] The above device adopts the design of equally spaced insertion holes during actual application, and uses a limiting rod inserted into the insertion hole to assist in limiting the vessel. However, during use, this method has some obvious drawbacks. When the magnetic stirrer needs to be used for different sizes of vessels, the limiting rod must be pulled out and then inserted into the corresponding hole inside. This operation is not only tedious, but also requires manual adjustment each time, which consumes a lot of time and effort. In addition, since there is a certain gap between the limiting rod and the vessel, the vessel may shake inside the limiting rod. Usually, the vessel used for magnetic stirring is relatively fragile, and long-term shaking and impact can cause wear and tear of the vessel, and even may cause the vessel to break. This situation not only affects the normal progress of the experiment, but also may cause certain safety hazards. Therefore, it can be seen that the existing technology indeed has certain defects and shortcomings in application. In order to improve the efficiency and safety of the experiment and meet the magnetic stirring needs of vessels of different sizes, it is urgent to improve and perfect it. UTILITY MODEL CONTENTS
