Description

Technical Field

[0001] This utility model relates to the field of stirrer technology, specifically a heating magnetic stirrer with a telescopic structure. Background Technology

[0002] A heated magnetic stirrer is a commonly used laboratory device that combines heating and stirring functions, providing convenience for processes such as chemical reactions and solution preparation.

[0003] Currently, in the existing technology, Chinese patent CN218901674U discloses a constant temperature heating magnetic stirrer. This device is equipped with a clamping component to hold a temperature measuring rod, so that the temperature measuring probe part of the rod is located inside the stirring cup and in contact with the heating liquid in the stirring cup. By clamping the temperature measuring rod, the possibility of displacement of the temperature measuring rod during temperature measurement is reduced, thereby reducing the possibility of contact between the temperature measuring probe and the cup wall, thus improving the accuracy of temperature measurement. However, in actual use, this device does not have a corresponding clamping component for the stirring cup, and the stirring cup may shift during the stirring process, thus affecting the stirring quality. In view of this, we propose a heating magnetic stirrer with a telescopic structure. Utility Model Content

[0004] The main objective of this invention is to provide a heating magnetic stirrer with a telescopic structure, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a heating magnetic stirrer with a telescopic structure, comprising a heating base, an auxiliary plate fixedly connected to the side wall of the heating base, a telescopic column fixedly connected above the auxiliary plate, a bolt threaded onto the telescopic column, a clamping sleeve fitted onto the telescopic column, a temperature measuring rod fitted onto the clamping sleeve, a fixing plate fixedly connected above the telescopic column, a second motor fixedly connected above the fixing plate, an auxiliary mechanism provided on the fixing plate, the auxiliary mechanism including a sleeve, the sleeve being fixedly connected to the output end of the second motor.

[0006] Preferably, the sleeve has a movable groove, the inner wall of the movable groove has a sliding groove, the sliding groove is slidably connected to a slider, the slider is fixedly connected to a sleeve rod, and a stirring rod is provided below the sleeve rod.

[0007] Preferably, the sleeve rod is fixedly connected to a spring, and the end of the spring away from the sleeve rod is fixedly connected to the end of the movable groove.

[0008] Preferably, auxiliary rods are fixedly connected to both side walls of the fixing plate, protrusions are fixedly connected below the auxiliary rods, a connecting plate is fixedly connected to the sleeve rod, and multiple sets of round blocks are fixedly connected below the connecting plate.

[0009] Preferably, a connecting plate is fixedly connected above the heating base, a positioning rod is fixedly connected to the connecting plate, a bidirectional lead screw is threaded to the connecting plate, a clamping plate is threaded to the bidirectional lead screw, and the clamping plate is slidably connected to the positioning rod. A motor is fixedly connected to the side wall of the connecting plate, and the motor is fixedly connected to the bidirectional lead screw through its output end.

[0010] Preferably, the heating base is equipped with a stirring cup. The first motor is then started to drive the bidirectional lead screw to rotate. With the cooperation of the positioning rod, this causes two sets of clamping plates to hold the stirring cup. After the stirring cup is clamped, the first motor is turned off. The operation is simple and convenient, ensuring the stability of the stirring cup. The temperature measuring rod and stirring rod are inserted into the stirring cup by pulling the telescopic column, and the telescopic column is fixed with bolts. Then, the second motor is started, and its output drive rotates the sleeve. With the cooperation of the sliding groove and the slider, the rotation of the sleeve causes the sleeve rod to rotate as well, thus rotating the stirring rod. Simultaneously, the rotation of the sleeve rod causes the connecting plate to rotate as well. The rotation of the connecting plate causes the round block to rotate. The continuous rotation of the round block continuously contacts the protrusion. With the cooperation of the spring, the sliding groove, and the slider, the sleeve rod continuously extends and retracts, causing the stirring rod to rotate while also reciprocating up and down, thus fully stirring the material in the stirring cup.

[0011] This invention provides a heating magnetic stirrer with a telescopic structure. It has the following beneficial effects:

[0012] (1) The heating magnetic stirrer with telescopic structure drives the bidirectional lead screw to rotate by starting the motor. With the cooperation of the positioning rod, it drives two sets of clamping plates to hold the stirring cup. After the stirring cup is clamped, the motor can be turned off. The operation is simple and convenient, thus ensuring the stability of the stirring cup.

[0013] (2) The heating magnetic stirrer with telescopic structure extends the temperature measuring rod and stirring rod into the stirring cup by pulling the telescopic column and fixing the telescopic column with bolts. Then, the second motor is started, and the output end of the second motor drives the sleeve to rotate. With the cooperation of the slide groove and the slider, the rotation of the sleeve will drive the sleeve rod to rotate together, thereby driving the stirring rod to rotate. At the same time, the rotation of the sleeve rod will drive the connecting plate to rotate together. The rotation of the connecting plate will drive the round block to rotate. The continuous rotation of the round block will continuously touch the protrusion. With the cooperation of the spring, slide groove and slider, the sleeve rod will continuously extend and retract, so that the stirring rod will perform reciprocating motion in the up and down direction while rotating, thereby making the stirring rod fully stir the material in the stirring cup.
