因此，如何改进安装底脚的结构，以降低装置的安装难度，成为本领域技术人员亟待解决的技术问题。

可选地，托台上开设有贯穿托台的主体板面厚度方向的第一光孔和第二光孔；第一调节部位于第一光孔上方，第二调节部位于第二光孔上方；且安装底脚还包括：第一连接件，其一端与第一调节部固定连接或与第一调节部为一体件，另一端穿过第一光孔并与第一光孔的下周缘配合，以限制第一调节部沿其旋转轴线方向相对于托台的直线运动自由度；和第二连接件，其一端与第二调节部固定连接或与第二调节部为一体件，另一端穿过第二光孔并与第二光孔的下周缘配合，以限制第二调节部沿其旋转轴线方向相对于托台的直线运动自由度。
可选地，第一连接件和第二连接件均为下缘周向带有多个外凸卡扣的中空筒状卡爪，每个外凸卡扣在其所处的卡爪的周壁区段之间具有间隙开口，且每个外凸卡扣的下表面为沿径向向外方向倾斜向上的斜面，每个外凸卡扣的上表面为与卡爪的周壁垂直的平面。
可选地，第一光孔的孔壁和第二光孔的孔壁在托台的下表面均形成有一个下环形凸缘，以与外凸卡扣的上表面形成卡扣配合。

本发明的安装底脚以及具有其的冰箱，安装底脚包括托座、滚轮、第一调节部和第二调节部。滚轮可转动地设置于托座的托台下方，第一调节部和第二调节部均具有可转动地设置于托台的螺杆、以及用于带动螺杆转动的调节旋盘。在安装过程中，由于滚轮可以沿安装底脚所在的支撑面滚动，螺杆可以相对于托台转动，使得本发明的安装底脚既适用于装置的调平过程，又适用于装置的移动过程，且体积小巧，简单易调节，调节范围大，制造成本低。采用本发明的安装底脚，可以降低装置的安装难度，提高安装效率，节省人工成本。

进一步地，本发明的安装底脚以及具有其的冰箱，由于每个螺杆可以相对于托台转动，当驱动每个调节旋盘带动对应的螺杆转动时，托台可以固定不动，从而可以防止滚轮在螺杆转动过程中随之转动，不仅使得装置的调平过程操作简便，省时省力，还会减少或避免滚轮磨损，延长安装底脚的使用寿命。
更进一步地，本发明的安装底脚以及具有其的冰箱，由于冰箱的安装底脚兼具有调平功能和移动功能，因此，可以减少或避免在冰箱的底部安装其他辅助结构，从而可以简化冰箱的安装结构，降低制造成本。
根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。
附图说明
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具 体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解，这些附图未必是按比例绘制的。附图中：
图1是根据本发明一个实施例的安装底脚的示意图；
图2是图1所示的安装底脚的剖视图；
图3是图1所示的安装底脚底部的部分区域的仰视图；
图4是图1所示的安装底脚的分解图；
图5是图4所示的安装底脚的连接件的部分区域的示意图；
图6是根据本发明一个实施例的冰箱的示意图。
具体实施方式
图1是根据本发明一个实施例的安装底脚10的示意图。本实施例的安装底脚10适于安装在装置的底部，用于将装置安装到设定位置。本实施例的安装底脚10可以适用于各种装置，例如冰箱70、空调、洗衣机等家用电器，也可以适用于任意其他设备，尤其适用于嵌入式的冰箱70。
安装底脚10一般性地可以包括滚轮、托座和调节部，还可以进一步地包括连接件。其中，滚轮安装于托座上。调节部通过连接件安装于托座上。调节部可以为两个，包括第一调节部400和第二调节部500。连接件也可以为两个，包括第一连接件和第二连接件。
托座包括托台210和下翻连轴部230。
托座的一部分形成托台210，托台210可以为托座上的水平板壁部。其中，“水平”是相对于安装底脚10的实际使用状态而言的。在一些可选的实施例中，托台210的板壁也可以为曲面。
托台210大致可以呈长方形，圆形，三角形或者其他任意多边形。本实施例中，托台210大致呈长方形。托台210上开设有贯穿托台210的主体板面厚度方向的光孔。本实施例中，光孔可以为两个，分别为第一光孔211和第二光孔212。第一光孔211和第二光孔212相对于托台210的中心轴线对称设置，中心轴线可以为沿托台210宽度方向延伸的中心轴线。其中，“宽度方向”和“长度方向”是相对而言的。
下翻连轴部230从托台210向下延伸，且具有用于与滚轮的轮轴310(将在下文详述)配合的轴孔231，以使滚轮的轮轴310可转动地连接于托座。本实施例中，下翻连轴部230可以为托座上的竖直侧壁部。下翻连轴部230 可以为两个，分别从托台210的相对的边缘部位处向下延伸形成。该“相对的边缘部位”可以为在托台210的宽度方向上相对的边缘部位。每个下翻连轴部230各具有轴孔231。两个下翻连轴部230的轴孔231相对设置。每个轴孔231与滚轮的轮轴310的一端配合。
在另一些可选的实施例中，可以对下翻连轴部230的位置和数量进行变换。下翻连轴部230可以为一个，从托台210的中间部位处向下延伸形成。下翻连轴部230的轴孔231可以与滚轮的轮轴310的中间区段配合。
在一些进一步的实施例中，托座还可以进一步地包括上翻止转部。上翻止转部从托台210向上延伸，用于插入安装于安装底脚10上的装置的相应卡槽内，以限制托台210相对于装置转动。优选地，上翻止转部从托台210的与调节部的调节旋盘(将在下文详述)存有间距的部位处向上延伸，这可以防止上翻止转部阻碍调节旋盘转动。
滚轮可滚动地设置于托台210下方，例如，滚轮大致可以位于托台210的中间部位的下方。滚轮包括沿水平方向延伸的轮轴310和绕轮轴310转动的轮体320。轮轴310的中心轴线可以与托台210的沿宽度方向延伸的中心轴线位于同一竖直面内。
第一调节部400位于第一光孔211上方，第二调节部500位于第二光孔212上方。每个调节部均具有一个螺杆和一个调节旋盘。
第一调节部400具有第一螺杆410和第一调节旋盘420。第一螺杆410可转动地设置于托台210。第一调节旋盘420与第一螺杆410固定连接或与第一螺杆410为一体件，以带动第一螺杆410转动。
第二调节部500具有第二螺杆510和第二调节旋盘520。第二螺杆510可转动地设置于托台210。第二调节旋盘520与第二螺杆510固定连接或与第二螺杆510为一体件，以带动第二螺杆510转动。
使用状态下的安装底脚10，每个螺杆与装置底部的螺纹孔螺接，其滚轮支撑在装置所在安装空间的支撑面上，例如，地面。在装置的安装过程中，由于滚轮可以沿安装底脚10所在的支撑面滚动，螺杆可以相对于托台210转动，使得本实施例的安装底脚10既适用于装置的调平过程，又适用于装置的移动过程。采用本实施例的安装底脚10，可以降低装置的安装难度，提高安装效率，节省人工成本。
例如，在装置的安装过程中，可以先进行移动步骤，然后进行调平步骤。 在移动过程中，滚轮沿支撑面滚动，可以降低移动过程中的摩擦阻力，降低移动难度。在调平步骤中，利用调节旋盘带动螺杆转动，可以调节螺杆旋入装置底部的螺纹孔的旋入深度，从而调节装置底部的高度和/或平行度，操作简便。
由于螺杆可以相对于托台210转动，当驱动调节旋盘带动螺杆转动时，托台210可以固定不动，从而可以防止滚轮在螺杆转动过程中随之转动，不仅使得装置的调平过程操作简便，省时省力，还会减少或避免滚轮磨损，延长安装底脚10的使用寿命。
本实施例的安装底脚10包括两个调节部。在装置的安装过程中，可以分别调节第一调节旋盘420和第二调节旋盘520，从而调节第一螺杆410和第二螺杆510旋入对应螺纹孔的深度，这有利于提高装置在安装调节过程中的调节平稳性和可靠性，减少或避免装置在安装调节过程中发生晃动，提高安装质量。
图2是图1所示的安装底脚10的剖视图。
第一调节旋盘420与第一螺杆410的旋转轴线与第一调节旋盘420的中心轴线及第一螺杆410的中心轴线同轴。第一调节旋盘420从第一螺杆410的底部区段沿径向向外延伸。第二调节旋盘520与第二螺杆510的旋转轴线与第二调节旋盘520的中心轴线及第二螺杆510的中心轴线同轴。第二调节旋盘520从第二螺杆510的底部区段沿径向向外延伸。
本实施例中，第一螺杆410的旋转轴线与第二螺杆510的旋转轴线均沿竖直方向延伸。也就是说，每个调节旋盘和对应螺杆的旋转轴线方向可以为竖直方向。每个螺杆可以从对应的调节旋盘的中间部位处向上延伸形成。且螺杆的头部可以埋设于调节旋盘内，这可以简化调节部的成型过程。螺杆的头部与螺杆为一体件。且螺杆的头部可以从螺杆的底部区段沿径向向外延伸形成。
第一调节旋盘420和第二调节旋盘520均为圆盘形。第一调节旋盘420的外周缘形成有多个第一轮齿421，以与扳手工具和/或传动带(例如，同步链条，同步带)配合。第二调节旋盘520的外周缘形成有多个第二轮齿521，以与扳手工具和/或传动带(例如，同步链条，同步带)配合。每个调节旋盘可以具有相同的设定厚度，以便于扳手工具和/或传送带对调节旋盘施加作用力。设定厚度可以根据实际应用情况进行设计，例如可以为0.5～10cm，也可 以为大于10cm的任意值。在另一些可选的实施例中，可以对调节旋盘的形状进行变换，例如，调节旋盘也可以为方形、六边形或者任意其他形状。
一般情况下，当装置的安装空间比较狭小时，由于安装人员无法触及装置的部分部位，这会限制安装人员在该部位对装置进行调节，导致调平过程十分困难。
本实施例的调节旋盘能与传动带配合，可以在安装人员易于操作的位置处设置主动件，例如，齿轮或外周缘带有凹槽的圆柱体。安装底脚10、传动带、主动件可以形成安装系统。将传动带绕设在主动件和调节旋盘上，通过转动主动件即可带动调节旋盘转动，从而可以大大降低装置的调平难度。
例如，当将冰箱70嵌入橱柜时，可以利用传动带带动调节旋盘转动，从而间接带动螺杆转动。由于橱柜内部空间有限，采用上述安装系统，可以降低冰箱70嵌入橱柜时的调平难度。
第二轮齿521与第一轮齿421传动啮合，可以使得第二调节旋盘520从动地随第一调节旋盘420转动。第一调节旋盘420的盘径大于第二调节旋盘520的盘径。其中，盘径是指圆盘的外周缘所在圆的直径。第一调节旋盘420的盘径大于第二调节旋盘520的盘径，这便于在安装底脚10上布置传动带，传动带可以套设于第一调节旋盘420上，从而直接带动第一调节旋盘420转动。第二调节旋盘520可以从动地布置在第一调节旋盘420的一侧，且位于传动带的内侧，从而在第一调节旋盘420的带动下随之转动。
本实施例的安装底脚10，在装置的安装过程中，还可以利用扳手工具和/或传动带调节第一调节旋盘420，并使第一调节旋盘420带动第二调节旋盘520转动，从而同时调节第一螺杆410和第二螺杆510旋入对应螺纹孔的深度，这既可以保证装置的调节平稳性，又可以简化安装底脚10的调节过程。
第一螺杆410的螺纹旋向与第二螺杆510的螺纹旋向相反，例如第一螺杆410的螺纹可以为正牙螺纹，第二螺杆510的螺纹可以为反牙螺纹。由于第二调节旋盘520从动地随第一调节旋盘420转动，将两个螺杆的螺纹旋向设置为相反，可以保证两个螺杆在对应螺纹孔内同步地旋进或旋出，从而保证第一调节部400和第二调节部500在调节过程中的一致性。
图3是图1所示的安装底脚10底部的部分区域的仰视图。图4是图1所示的安装底脚10的分解图。图5是图4所示的安装底脚10的连接件的部分区域的示意图。
第一连接件的一端与第一调节部400固定连接或与第一调节部400为一体件，另一端穿过第一光孔211并与第一光孔211的下周缘配合，以限制第一调节部400沿其旋转轴线方向相对于托台210的直线运动自由度。第二连接件的一端与第二调节部500固定连接或与第二调节部500为一体件，另一端穿过第二光孔212并与第二光孔212的下周缘配合，以限制第二调节部500沿其旋转轴线方向相对于托台210的直线运动自由度。也就是说，在装置的安装过程中，调节部沿其旋转轴线转动时，连接件会阻止对应的调节部相对于托台210沿竖直方向移动，使得调节部在竖直方向上不会相对于托台210发生位移。
每个连接件不与对应光孔的下周缘固定连接，可仅使调节部自身进行转动，而不会带动托台210一同转动，从而能减小转动阻力，提高安装效率。
每个连接件均可以为卡爪600。第一连接件和第二连接件均为下缘周向带有多个外凸卡扣610的中空筒状卡爪600。每个连接件可以从调节旋盘的底壁向下延伸，穿过对应的光孔，以与光孔的下周缘配合。
每个外凸卡扣610在其所处的卡爪600的周壁区段之间具有间隙开口620，即，外凸卡扣610沿卡爪600下缘的周向依次间隙排列。当将卡爪600下缘插入光孔时，卡爪600下缘的外周受到沿径向向内的作用力而向内侧收缩，从而可以顺利穿过光孔。
每个外凸卡扣610的下表面为沿径向向外方向倾斜向上的斜面，这有利于使卡爪600下缘平滑地穿过光孔。其中，“向外”是相对于中空筒状卡爪600的实际使用状态而言的。
中空筒状卡爪600的中心轴线沿竖直方向延伸。每个外凸卡扣610的上表面为与卡爪600的周壁垂直的平面，大致可以为水平面。每个外凸卡扣610的上表面可以与对应光孔的孔壁形成卡扣配合。第一光孔211的孔壁和第二光孔212的孔壁在托台210的下表面均形成有一个下环形凸缘202，以与外凸卡扣610的上表面形成卡扣配合，这有利于避免外凸卡扣610的上表面与托台210的主体板面接触。
第一光孔211的顶部区段和第二光孔212的顶部区段均可以为喇叭口状。每个调节部可以通过一环形垫圈或形成在调节部的下表面上的环形凸起452抵压于托台210的上表面，这可以减小调节部与托台210上表面的接触面积，有利于降低调节部转动时的摩擦阻力。环形垫圈可以设置于调节旋盘 下表面与托台210上表面之间。环形凸起452可以形成于调节旋盘的下表面。每个调节部的环形凸起452可以抵压于对应光孔的外周上。
在一些可选的实施例中，调节部也可以不设置环形垫圈和环形凸起452，调节部的下表面可以为平面状，并且直接抵压于托台210的上表面，这有利于提高安装底脚10的机械强度。
图6是根据本发明一个实施例的冰箱70的示意图。冰箱70的底部设置有至少一个上述任一实施例的安装底脚10。且冰箱70的底部开设有第一螺纹孔和第二螺纹孔。安装底脚10的螺杆与螺纹孔螺接。第一螺杆410与第一螺纹孔螺接，第二螺杆510与第二螺纹孔螺接。
由于本实施例的冰箱70中安装底脚10兼具有调平功能和移动功能，因此，可以减少或避免在冰箱70的底部安装其他辅助结构，从而可以简化冰箱70的安装结构，降低制造成本。
安装底脚10可以为四个，其中的两个可以设置于冰箱70的底部前侧，另外的两个可以设置于冰箱70的底部后侧。
在另一些可选的实施例中，安装底脚10可以为两个，且均设置于冰箱70的底部后侧。冰箱70的底部前侧可以设置有可滚动的前轮。
螺纹孔形成于冰箱70的底板上。底板可以直接为冰箱70的箱体的底板，也可以为在箱体上额外增设的底板。冰箱70的底板上形成有从底板所在板面向上延伸的螺筒，螺筒的内部形成螺纹孔。
本实施例的安装底脚10以及具有其的冰箱70，安装底脚10包括托座、滚轮、第一调节部400和第二调节部500。滚轮可转动地设置于托座的托台210下方，第一调节部400和第二调节部500均具有可转动地设置于托台210的螺杆、以及用于带动螺杆转动的调节旋盘。在安装过程中，由于滚轮可以沿安装底脚10所在的支撑面滚动，螺杆可以相对于托台210转动，使得实施例的安装底脚10既适用于装置的调平过程，又适用于装置的移动过程，且体积小巧，简单易调节，调节范围大，制造成本低。采用实施例的安装底脚10，可以降低装置的安装难度，提高安装效率，节省人工成本。
本实施例的安装底脚10以及具有其的冰箱70，第一调节部400的第一调节旋盘420和第二调节部500的第二调节旋盘520均为外周缘带有轮齿的圆盘，第二调节旋盘520的轮齿可以与第一调节旋盘420的轮齿传动啮合，在装置的安装过程中，还可以利用扳手工具和/或传动带调节第一调节旋盘 420，并使第一调节旋盘420带动第二调节旋盘520转动，从而同时调节第一螺杆410和第二螺杆510旋入对应螺纹孔的深度，这既可以保证装置的调节平稳性，又可以简化安装底脚10的调节过程。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
