Description

Technical Field

[0001] The utility model relates to the technical field of crucibles, and more particularly to a crucible for experiments. Background Art

[0002] A crucible is a cup-shaped vessel used in laboratories for high-temperature heating of solids.

[0003] During the use of existing experimental crucibles, when heating materials, in most cases, it is necessary to stir the materials while heating. Usually, a heating through groove is provided on the crucible cover rod to shake and stir the glass plate. However, due to the vertical structure of the glass plate, the stirring rotation speed is the same as the shaking speed, which requires the operator to operate quickly, increasing the labor intensity of the operator. Therefore, we propose a crucible for experiments. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a crucible for experiments to solve the problems existing in the above background art.

[0009] Further, the movable stirring mechanism includes a rotating installation rod, a driven gear is fixedly connected to the top of the rotating installation rod, a fixed limiting ring is fixedly sleeved on the outer surface of the rotating installation rod, a connecting stirring arm is fixedly connected to the lower part of the outer surface of the rotating installation rod, and a conical block is fixedly connected to the bottom end of the rotating installation rod.

[0010] Furthermore, the connecting teeth are meshed and connected with the driven gear.

[0011] Furthermore, the fixed plugging mechanism includes a connecting sleeve. A second fixed through groove is formed on the outer side of the surface of the connecting sleeve. An active connecting rod is movably connected inside the connecting sleeve. A connecting mounting disc is fixedly connected to the bottom of the active connecting rod. Connecting plugging rods are symmetrically arranged at the bottom of the connecting mounting disc. A stress spring is fixedly connected to the top of the connecting mounting disc. A connecting mounting top ring is fixedly connected to the top of the stress spring. A connecting pulling disc is fixedly connected to the top of the active connecting rod.

[0012] The technical effects and advantages of the present utility model:

[0013] 1. By providing the fixed positioning frame, the fixed guiding block, the moving driving mechanism and the active stirring mechanism, the fixed positioning frame and the fixed guiding block can guide and limit the moving driving mechanism. Then, by moving the moving driving mechanism horizontally back and forth, the moving driving mechanism can drive the active stirring mechanism, enabling the active stirring mechanism to rotate and stir, thereby fully stirring the materials inside the crucible body, and the operation is convenient.

[0014] 2. By providing the fixed through hole and the fixed plugging mechanism, when heating the materials, the fixed plugging mechanism can plug the fixed through hole to avoid heat loss during heating. If the materials will volatilize gas to the outside during heating, in order to avoid the pressure inside the crucible body from increasing, the fixed plugging mechanism can be adjusted before heating to open the fixed through hole, improving the overall practicality.
