DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0022] The utility model discloses a laboratory magnetic stirrer mainly used in the field of magnetic stirrers.

[0023] Reference Figures 1 to 5 A laboratory magnetic stirrer comprises: a placing plate 1, a container 2 is arranged on the top of the placing plate 1, a mounting plate 3 is fixedly connected to the top of the placing plate 1, a through groove 4 is opened inside the mounting plate 3, a connecting plate 5 is slidably connected inside the through groove 4, a stirring rod 6 is arranged at the bottom of the connecting plate 5, an adjusting component is arranged inside the through groove 4, two clamping plates 16 are arranged on the outside of the container 2, a connecting component is arranged inside the placing plate 1, and the connecting component is used to drive the clamping plate 16 to move.

[0024] In the above technical solution, it is taken into account that in the prior art, bolt clamps are used to fix the container to ensure the stability of the container, but the heights and calibers of the containers in the laboratory are different, and the method of fixing the container with transmitted bolts is convenient for fixing containers of different heights. In order to solve such problems, the specific operations are as follows: by setting a connecting component to drive the clamp 16 to move above the placement plate 1, clamping and fixing the container 2 from both sides, the stability of the container 2 is effectively improved, and the risk of leakage or dumping caused by vibration or movement during the stirring process is reduced. At the same time, the device can adapt to containers 2 of different calibers, has great flexibility, and can handle a variety of experimental needs. By setting an adjustment component, the stirring rod 6 can be driven to move up and down, so that the device can adapt to containers 2 of different heights. The experimenter can easily adjust the height of the stirring rod 6 to ensure that it is always in the optimal stirring position.

[0025] Reference Figures 1 to 5 The outer side of the gear 13 is fixedly connected to the gear 14, and the outer side of the gear 13 is screwed to the gear 14, and the gear 14 is engaged with the gear 14.

[0026] In the above technical solution, considering that there is a problem in the prior art that bolt clamps are used to fix the container to ensure the stability of the container, but the heights and calibers of the containers in the laboratory are different, the method of fixing the container with transmission bolts is convenient for fixing containers of different heights. In order to solve such problems, the specific operation is as follows: place the container 2 in the middle of the placement plate 1, then start the motor 10 to drive the screw 8 to rotate, thereby driving the two racks 11 to move in the opposite direction, and utilizing the meshing relationship between the rack 11 and the spur gear 13 to further drive the spur gear 13 and the rotating rod 12 to rotate, and then drive the connecting rod 14 to swing in the slot 17, thereby allowing the clamp 16 to approach the container 2. When the corners on the clamp 16 conflict with the outer wall of the container 2, under its rotation relationship, the clamp 16 will slowly fit together with the container 2, and finally clamp and fix the container 2. The connecting rod 14 has a large range of motion, so that it can flexibly adapt to containers 2 of different heights and calibers without manual adjustment, which greatly enhances the applicability of the equipment. The provision of a rubber pad can protect the clamp 16 and the container 2 to avoid hard contact and scratches.

[0027] Reference Figures 1 to 5 In a preferred embodiment, the adjustment assembly includes a threaded rod 18, which is rotatably connected to the interior of the through slot 4, and the outer side of the threaded rod 18 is threadedly connected to the inner side of the connecting plate 5. One side of the mounting plate 3 is rotatably connected to a connecting rod 19, one end of the connecting rod 19 extends to the interior of the through slot 4 and is fixedly connected to a first bevel gear 20, and the outer side of the threaded rod 18 is fixedly connected to a second bevel gear 21, and the first bevel gear 20 is meshed with the second bevel gear 21;

[0028] In the above technical solution, the problem of containers of different heights is taken into consideration. In order to solve such problems, the specific operations are as follows: the first bevel gear 20 is driven to rotate by rotating the connecting rod 19, and then the meshing relationship between the first bevel gear 20 and the second bevel gear 21 is utilized to further drive the second bevel gear 21 and the threaded rod 18 to rotate, thereby driving the connecting plate 5 to move up and down, and then adjusting the height of the stirring rod 6, so that the device can be quickly adjusted to containers 2 of different heights, so that the stirring rod 6 can adapt to the needs of various containers 2, thereby improving the versatility of the equipment.

[0029] Working principle: When in use, first place the container 2 in the middle of the placing plate 1, then start the motor 10, drive the screw rod 8 to rotate, thereby driving the two racks 11 to move in the opposite direction, and utilize the meshing relationship between the rack 11 and the spur gear 13 to further drive the spur gear 13 and the rotating rod 12 to rotate, and then drive the connecting rod 14 to swing in the slot 17, thereby allowing the splint 16 to approach the container 2. When the corners above the splint 16 conflict with the outer wall of the container 2, under its rotation relationship, the splint 16 will slowly fit together with the container 2, and finally clamp the container 2 and fix it. Then, the first bevel gear 20 is driven to rotate by rotating the connecting rod 19, and then the meshing relationship between the first bevel gear 20 and the second bevel gear 21 is utilized to further drive the second bevel gear 21 and the threaded rod 18 to rotate, thereby driving the connecting plate 5 to move up and down, and then adjusting the height of the stirring rod 6, and the experiment can be carried out.
