Description

Technical Field

[0001] The present application relates to the technical field of quartz crucibles, and in particular to a quartz crucible with high stability. Background Art

[0002] Quartz crucibles have the advantages of high purity, strong temperature resistance, large size and high precision, good thermal insulation, energy saving, and stable quality. They are used more and more widely. The detection of quartz crucibles is a very important link, and the detection of quartz crucibles is developing towards on-site detection. Existing quartz crucibles have certain instability when placed or installed. Moreover, because the quartz crucible itself is brittle and easy to break, it is very easy to break when placed by workers, which directly increases the cost of using quartz crucibles. Therefore, a quartz crucible with high stability is needed.

[0003] According to the announcement number: CN216967495U, a quartz crucible with high stability is disclosed. This technology discloses "a quartz crucible body, the quartz crucible also includes a supporting seat, the supporting seat is arranged directly below the quartz crucible body, the top side wall of the supporting seat is provided with a placement groove, the quartz crucible body is placed in the placement groove, the top side wall of the supporting seat slides through a plurality of symmetrically distributed support plates, the side wall of the support plate away from the supporting seat is fixed with a bottom plate; an additional plate, two additional plates are provided, etc. The utility model has the technical effect of the base being moved downward by the elastic force of spring a, and the base stretching spring b when moving, and the elastic force of spring b makes the quartz crucible body and the base fit more firmly."

[0004] In response to the above-mentioned related technologies, the inventor believes that the existing quartz crucible structure is not stable enough when placed. Since the bottom of the crucible is curved, the crucible is prone to tilting and damage during the placement process. It does not have a centering positioning mechanism, which makes it inconvenient to place the crucible firmly, reducing the stability of the crucible placement; secondly, the existing quartz crucible structure does not have a lifting assembly. Since the crucible needs to be taken out of the placement slot when using it, and since a frame is set on the outside of the crucible placement seat, it is not convenient to take out the crucible. There is no lifting assembly, which makes it inconvenient to take the crucible out of the placement slot, reducing the convenience of using the crucible structure. Utility Model Content
