上滑动门16以及下滑动门17可以在对开口进行封闭的封闭位置以及打开开口的打开位置之间进行滑动。当上滑动门16以及下滑动门17滑动到封闭位置时，对开口进行密封。
支撑机构安装在开口处，用于对滑动开合机构进行支撑，包括支架1612以及卡合件。支架1612就相当于支撑架。
支架1612具有台阶部、延伸板安装槽1607(相当于第四限位槽)、第一卡合槽1605(相当于第二限位槽)以及第二卡合槽1611(相当于第一限位槽)。
台阶部设置在开口两端，具体地，设置在开口的两个长边所在的两端。台阶部包括第一台阶1613(相当于第一滑动台阶)和设置在第一台阶1613下方的第二台阶1614(相当于第二滑动台阶)。
第一台阶1613沿开口的长边方向延伸，对上滑动门16进行承托并使该上滑动门16沿第一台阶1613的延伸方向滑动。具体地，第一台阶1613对上滑动门16的上滑块1603进行承托并使上滑块1603沿第一台阶1613的延伸方向滑动。
第二台阶1614沿开口的长边方向延伸，对下滑动门17进行承托并使该上滑动门17沿第二台阶1614的延伸方向滑动。具体地，第二台阶1614对下滑动门17的下滑块1703进行承托并使下滑块1703沿第二台阶1614的延伸方向滑动。
在第二台阶1614的下方还设有第三滑动台阶1615，用于承托托架4，在托架4上安装有网篮5。
延伸板安装槽1607设置在第一台阶1613的上方，该延伸板安装槽1607向平行于上滑块1603的上表面的方向延伸。在延伸板安装槽1607内设有沿垂直于上滑块1603的上表面的方向延伸的延伸板限位槽。
第一卡合槽1605设置在第一台阶1613的上方，与上滑动门16的端部，也就是上滑块1603的端部相对。
第二卡合槽1611设置在支架1612远离开口的外侧面上。
卡合件卡合在支架1612上，具有卡合件本体1609(相当于第二限位凸筋)、嵌入第一卡合槽1605的钩部1606(相当于第三限位凸筋)、嵌入第二卡合槽1611的卡合凸部1610(相当于第一限位凸筋)。

支撑机构还具有限位块本体1601。限位块本体1601与支撑架1602之间形成了第三限位槽1608，在第三限位槽1608内设有卡合件本体1609。
上滑块16和下滑块17滑动到封闭位置时，分别插入到限位块本体1601中形成密封。
密封机构具有安装在支撑机构上的延伸部1604(相当于第一限位挡板)以及挡板1703(相当于第二限位挡板)
延伸部1604设置在延伸板1604，位于上滑动门16的上方，与上滑动门16之间形成间隙。具体地，延伸板1604嵌在延伸板安装槽1607中，并且延伸板1604具有与延伸板限位槽相配合对延伸板1604进行限位的凸起。
上滑动门16和下滑动门17滑动到封闭位置时，在竖直方向上形成重叠部分，本实施例一中，延伸板1604仅设置在重叠部分的上方，在其他实施例中，延伸板1604也可以设置在整个上滑动门16和下滑动门17的上方。
挡板1703设置在下滑块1702上，在靠近第二台阶1613的位置处向下延伸，并且与第二台阶1613的向下延伸的台阶面之间形成间隙。
实施例一的作用与效果
本实施例一中，提供了一种柜门装置以及具有该柜门装置的冷冻柜。柜门装置具有上下交错的上滑动门和下滑动门，对上滑动门和下滑动门进行承托的第一台阶和第二台阶，上滑动门可以沿第一台阶滑动，下滑动门可以沿第二台阶滑动，在上滑动门的上方设有安装在支撑机构上的延伸部，并且延伸部与上滑动门之间形成间隙，利用延伸部与上滑动门的上滑块之间的间隙配合提高了上滑动门闭合后的密封性。并且通过延伸部的结构使得冷冻柜柜体内的冷气需要经过弯曲的通路才能到达外界，因此可以有效避免冷冻柜柜体内冷气的溢散。
另外，将延伸部设置成延伸板，在支架上设有用于让延伸板嵌入的延伸板安装槽，并在该延伸板安装槽设有对延伸板上的凸起进行限位的延伸板限位槽，保证了延伸板安装的稳定性。
另外，上滑动门和下滑动门在滑动到封闭位置时，插入限位块本体中，实现了在封闭位置对冷冻柜柜体的开口的密封，与延伸部相配合，进一步提高了冷冻柜的冷冻柜性。
另外，上滑动门和下滑动门在滑动到封闭位置时，形成重合部分，延伸部仅设置在重合部分的上方，就可以提高对冷冻柜柜体开口的密封性，结构简单，易于制造。
另外，在下滑动门的滑块上还设有向下延伸的挡板，挡板与第二台阶之间具有间隙，通过间隙配合进一步提高了下滑块与冷冻柜柜体之间的密封性，可以有效避免冷冻柜柜体内冷气的溢散。
另外，在上滑动门和下滑动门上分别设置可以透视的一透视窗和第二透视窗，使得用户在使用该冷冻柜时，可以直观的观察冷冻柜内 存储的物品。
<实施例二>
如图7所示，本实施例二提供一种新的柜门装置，具有与实施例一相同的滑动开合机构以及支撑机构。另外，本实施例二的密封机构还具有与实施例一相同的延伸部1604以及挡板1703。
与实施例一不同之处在于，本实施例二的密封机构还具有密封垫1616(相当于密封橡胶垫)，该密封垫1616设置在延伸部1604的底面，也就是延伸部1604朝向上滑块1603的一侧面与上滑块1603之间。
在密封垫1616的底面设有环形密封槽1617。由于环形密封槽1617与延伸部以及上滑动门16配合提高了密封性，当有冷气从上滑动门16与第一台阶1613之间溢散时，可以减缓冷气溢散的速度，进一步保证了冷冻柜的制冷效果，降低了冷冻柜的耗电量。
上述实施例仅用于举例说明本发明的具体实施方式，而本发明不限于上述实施例的描述范围。
