Description

Technical Field

[0001] This utility model belongs to the field of magnetic stirrers, specifically a heated magnetic stirrer. Background Technology

[0002] Magnetic stirrers are laboratory instruments used for mixing liquids, primarily for stirring or simultaneously heating and stirring low-viscosity liquids or solid-liquid mixtures. Their basic principle utilizes the repulsion and attraction of like poles in a magnetic field. The magnetic field drives a magnetic stir bar placed in a container to rotate in a circular motion, thus achieving the purpose of stirring the liquid. Magnetic stirrers require a heating and temperature control system to heat and control the sample temperature according to specific experimental requirements, maintaining the necessary temperature conditions to ensure the liquid is mixed to the required level. However, existing magnetic stirrers lack protective measures during use and are easily damaged by impacts. Therefore, we have designed a retractable protective device for heated magnetic stirrers.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] A heated magnetic stirrer, such as Figure 1 , 2As shown in Figures 3 and 4, the device includes a box body 1, inside which a magnetic stirrer body 2 is housed. The box body 1 has an opening on its upper side. A fixing plate 4 is hinged to the top side of the box body 1 via a first damping shaft 3. A crossbar 6 is hinged to the fixing plate 4 via a second damping shaft 5. A sliding sleeve 7 is fixedly mounted on the crossbar 6, and a temperature measuring rod 8 slides within the sliding sleeve 7. The sliding sleeve 7 has a limiting mechanism to restrict the vertical movement of the temperature measuring rod 8. The fixing plate 4 can house the crossbar 6 and the temperature measuring rod 8 within the box body 1. This utility model has a simple structure and ingenious design. By housing the temperature measuring rod 8 and connecting components within the box body 1, it achieves a protective effect, meets market demands, and is suitable for widespread application. When using this invention, the magnetic stirrer body 2 is initially located inside the box 1. When needed, first rotate to open the fixing plate 4, then rotate to open the crossbar 6. Place the container holding the liquid on the heating plate of the magnetic stirrer body 2, and then place the stir bar in the container. Adjust the height of the temperature measuring rod 8 using the limiting mechanism so that the bottom of the temperature measuring rod 8 is placed in the container. After use, rotate the crossbar 6 forward and the fixing plate 4 downward in sequence so that the crossbar 6 is placed inside the box 1, and the fixing plate 4 abuts against the top side of the box 1. At this point, storage is complete. The box 1 and the fixing plate 4 can protect the magnetic stirrer body 2 inside.

[0017] Specifically, as shown in the figure, the limiting mechanism in this embodiment includes a fastening bolt 20, a threaded hole 21 on the sliding sleeve 7, and a protective sleeve 22 fixedly fitted on the outer periphery of the top of the temperature measuring rod 8. The fastening bolt 20 and the outer periphery of the protective sleeve 22 are in abutting contact. The fastening bolt 20 can limit the protective sleeve 22, thereby facilitating the adjustment of the height of the temperature measuring rod 8.

[0018] Specifically, as shown in the figure, the side wall of the box body 1 and the fixing plate 4 of this embodiment are respectively provided with grooves 31, and the same C-shaped block 30 is inserted into the grooves 31. The two ends of the C-shaped block 30 can be inserted into the grooves 31 provided in the side wall of the box body 1 and the fixing plate 4, thereby limiting the fixing plate 4 and keeping it in a vertical state.

[0019] Furthermore, as shown in the figure, in this embodiment, C-shaped rods 40 are provided on the front and rear sides of the crossbar 6, and the C-shaped rods 40 are inserted into the through slots 41 opened in the fixing plate 4. The two ends of the C-shaped rods 40 pass through the through slots 41 to limit the crossbar 6, preventing the crossbar 6 from shaking back and forth due to force during stirring.

[0020] Furthermore, as shown in the figure, in this embodiment, protective plates 50 are slidably fitted on the front, rear, and right sides of the box body 1. Through holes 51 are respectively opened on the protective plates 50, and bolts 52 are slidably fitted into the through holes 51. Two vertically distributed second threaded holes 53 are respectively opened on the front, rear, and right side walls of the box body 1, and the bolts 52 are threaded into the second threaded holes 53. Moving the protective plate 50 upwards allows the bolts 52 to be inserted into the second threaded holes 53 at the top, thereby raising the protective plate 50 and preventing splashing during stirring.

[0021] Furthermore, as shown in the figure, in this embodiment, two vertical dovetail grooves 60 are respectively provided on the front, back, and right side walls of the box body 1. Dovetail sliders 61 are slidably fitted in the dovetail grooves 60, and the dovetail sliders 61 are fixedly installed on the corresponding protective plates 50. When the protective plates 50 move up and down, they can drive the dovetail sliders 61 to slide within the dovetail grooves 60.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
