Description

Technical Field

[0001] The utility model relates to the technical field of vacuum furnaces, in particular to an electrode connection structure for a vacuum furnace. Background Art

[0002] A vacuum furnace uses a vacuum system (carefully assembled from components such as a vacuum pump, a vacuum measuring device, and a vacuum valve) to discharge some of the material in the furnace cavity, making the pressure in the furnace cavity less than one standard atmospheric pressure, thereby achieving a vacuum state in the furnace cavity.

[0003] In the prior art, for example, the patent publication number CN220728940U states, "A vacuum furnace electrode connection structure," which includes an electrode body, a fixed disk disposed on the outside of the electrode body, a fixing hole formed on the fixed disk, a through cavity formed in the fixed disk, guide frames fixed at both ends of the fixed disk, and a movable plate installed in the guide frame. The beneficial effect is that the utility model provides a transition connection structure consisting of a telescopic column, a spring, a movable plate, a limit rod, and a limit hole. During use, the limit rod is located in the limit hole to fix the electrode body. When maintenance is required, the fixation can be released by applying an external force to the movable plate to compress the telescopic column and the spring and separate the limit rod from the limit hole. Repeating the above operation during installation allows the limit rod to be located in the limit hole by relying on the rebound force of the spring and the telescopic column when the external force is released. This eliminates the need to disassemble the fixed disk, effectively improving the portability of the connection structure.
