Description

Technical Field

[0001] The utility model relates to the technical field of connection structures, in particular to a connection structure between a charging quartz tube and a weight. Background Art

[0002] The Czochralski method is a commonly used method for growing single crystals. Its working principle is to heat and melt the raw materials constituting the crystal in a crucible, connect a seed crystal to the surface of the melt and pull the melt. Under controlled conditions, the atoms or molecules of the seed crystal and the melt are continuously rearranged at the interface, and the single crystal grows as the temperature drops and gradually solidifies. After the crystal is pulled through one rod, a secondary feeding is carried out into the single crystal furnace through a feeding quartz tube. After the feeding is completed, the crystal is pulled. When loading, a heavy hammer can be connected to the feeding quartz tube, and the heavy hammer is lifted to drive the feeding quartz tube to rise into the furnace cover, so that the loading amount of the crucible can be increased. The original single crystal furnace feeding quartz tube uses a directly connected hook to connect with the heavy hammer, which is complicated to operate and prone to interference, resulting in accidents and adverse effects on production work. Therefore, a connection structure of the feeding quartz tube and the heavy hammer is proposed. Utility Model Content
