进一步的为了提高卡箍的整体强度，所述的下卡箍底部与隔板之间的中空部内填充有保温材料。填充保温材料后整体强度提高。
进一步的，所述的保温材料为硬质保温材料。硬质保温材料能够有效的提供支撑力。
进一步的，所述的保温材料为气凝胶绝热毡。气凝胶绝热毡的隔热性能更优。
作为优选，所述的保温材料包括硬质保温材料和气凝胶绝热毡，所述的硬质保温材料贴合在下卡箍上，所述的气凝胶绝热毡位于硬质保温材料和隔板之间。采用硬质保温材料和气凝胶绝热毡的组合形式，在有效提供支撑力的同时，提高保温性能。
进一步的，所述的保温材料层包括二圈，外圈为硬质保温层，内圈为软质保温层。
具体实施方式，所述的隔板呈圆弧形，或隔板由至少两块直板连接而成。
