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10是根据本发明一个实施例的冰箱的底板和底脚调节系统的示意图。
具体实施方式
图1是根据本发明一个实施例的底脚调节系统10的示意图。本实施例的底脚调节系统10适于安装在装置的底部，用于将装置安装到设定位置。本实施例的底脚调节系统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。
底脚调节系统10一般性地可以包括主动转轮120、传动带150和底脚110。其中，传动带150套设于主动转轮120和底脚110上。
传动带150可以为同步带或同步链条，也可以为任意其他类型。本实施例中，传动带150可以为同步带。本实施例仅以传动带150为同步带的情况进行示例，本领域技术人员在了解本实施例的基础上应当完全有能力针对其他类型的传动带150进行拓展，在此不再一一示出。
图2是图1所示的底脚调节系统10的分解图，图3是图2中A处的局部放大图。
同步带的内周缘形成有带齿151。同步带可以为环形。同步带通过其内周缘与主动转轮120和底脚110相啮合。带齿151可以沿同步带的内周缘间隔均匀分布。
主动转轮120包括主动转轴121和主动旋盘122，还可以进一步地包括支撑板123。主动转轮120的一部分形成主动转轴121。传动带150可以套设于主动转轴121的外周。主动转轴121可以为齿轮轴，其外周缘形成有与带齿151啮合的第一轮齿121a。主动旋盘122为圆盘形，主动旋盘122的外周形成有至少一个凹槽或凸起，以与扳手工具和/或另一传动带150配合。并且主动旋盘122与主动转轴121固定连接或与主动转轴121为一体件，以带动主动转轴121转动。也就是说，主动旋盘122可以在扳手工具和/或另一传 动带150的驱动下转动，从而带动主动转轴121转动。
本实施例中，主动旋盘122和主动转轴121的旋转轴线与主动旋盘122的中心轴线、以及主动转轴121的中心轴线同轴。主动旋盘122的中心轴线和主动转轴121的中心轴线均可以沿竖直方向延伸。
主动旋盘122从主动转轴121的底部区段沿径向向外延伸。也就是说，主动转轴121可以大致位于主动旋盘122的上方。
主动旋盘122不仅用于带动主动转轴121转动，还形成主动转轴121的底座，以支撑主动转轴121。主动转轴121的直径可以小于主动旋盘122的盘径，盘径是指圆盘的外周缘所在圆的直径，这可以提高主动转轮120的结构稳定性。本实施例中，主动旋盘122用于支撑在装置所在的支撑面(例如，地面)上。
支撑板123可以位于主动转轴121的顶端，既可以将同步带限定在主动转轴121上，又可以抵靠于装置的底部。
底脚110一般性地可以包括螺杆410和从动旋盘420，还可以进一步地包括托座200和滚轮300。其中，螺杆410和从动旋盘420形成底脚110的调节部400。调节部400可以连接于托座200。
螺杆410用于可转动地螺接于安装有底脚调节系统10的装置的底部螺纹孔中，从动旋盘420的外周套接于传动带150，以与主动转轴121传动连接，且从动旋盘420与螺杆410固定连接或与螺杆410为一体件，以带动螺杆410转动。
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。
螺杆410具有外螺纹，可以与装置的底部螺纹孔螺接。螺杆410转动时，可以调节螺杆410旋入装置底部螺纹孔的深度。采用本实施例的底脚调节系统10，可以在安装人员易于操作的位置处设置主动转轮120。通过驱动主动转轴121转动，利用传动带150的传动作用即可间接地驱动从动旋盘420转动，从而驱动螺杆410转动，可以明显降低装置的调平难度，降低装置的安装难度。
例如，当将冰箱70嵌入橱柜时，可以在冰箱70的底部前侧安装主动转轮120，底脚110可以安装于冰箱70的底部后侧，可以利用传动带150带动 从动旋盘420转动，从而间接带动底脚110的螺杆410转动。由于橱柜内部空间有限，采用本实施例的底脚调节系统10，可以降低冰箱70嵌入橱柜时的调平难度。
传动带150同时套设于主动转轴121的外周、以及从动旋盘420的外周。从动旋盘420可以为圆盘形，其外周缘形成有与带齿151啮合的第二轮齿421。
主动转轴121和从动旋盘420可以具有相同的设定厚度，以便于与传动带150配合。设定厚度可以根据实际应用情况进行设计，例如，可以与传动带150的带宽相适配。例如，设定厚度可以为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，可以对从动旋盘420的形状进行变换，例如，可以为四方柱形、六方柱形或者任意其他形状。
从动旋盘420和螺杆410的旋转轴线与从动旋盘420的中心轴线以及螺杆410的中心轴线同轴。且从动旋盘420从螺杆410的底部区段沿径向向外延伸。本实施例中，从动旋盘420和螺杆410的旋转轴线方向可以为竖直方向。螺杆410可以从从动旋盘420的中间部位处向上延伸形成。例如，螺杆410可以从从动旋盘420的中间部位处向上延伸形成。且螺杆410的头部可以埋设于从动旋盘420内，这可以简化调节部400的成型过程。其中，螺杆410的头部与螺杆410为一体件。且螺杆410的头部可以从螺杆410的底部区段沿径向向外延伸形成。
托座200的一部分形成托台210。从动旋盘420设置于托台210。滚轮300可滚动地设置于托台210下方。
使用状态下的底脚调节系统10，其螺杆410与装置底部的螺纹孔螺接，其滚轮300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300可以沿装置所在的支撑面滚动，螺杆410可以相对于装置的底部螺纹孔转动，使得本实施例的底脚调节系统10既适用于装置的调平过程，又适用于装置的移动过程。采用本实施例的底脚110，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300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，驱动螺杆410转动，可以调节螺杆410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。
托座200可以为圆柱形，方柱形(其顶壁和底壁均为长方形)，或者可以为其他任意形式的柱状。
图4是图1所示的底脚调节系统10中底脚110的示意图。
本实施例中，托座200可以为圆柱形。滚轮300可以为球形，且为多个，托座200具有水平底壁部、水平顶壁部以及连接于水平底壁部和水平顶壁部之间的柱体。托座200的水平底壁部(即，圆柱的底面)和水平顶壁部(即，圆柱的顶面)均呈圆形，且均位于水平面上。
托座200的水平底壁部的一部分向内凹陷形成有多个球窝部。其中，“向内”是相对于托座200的实际使用状态而言的，大致可以为向上方向。球窝部限定出滚轮300的活动空间。每个滚轮300可滚动地嵌设于一个球窝部。
球窝部的数量为不小于3，例如，可以为3个或者4个。多个球窝部在以水平底壁部的中心为圆心的同一圆周上间隔均匀分布。
托台210即为托座200上的水平顶壁部。从动旋盘420可以与托台210为一体件，并从托台210向上延伸形成。也就是说，从动旋盘420位于托台210上方。从动旋盘420的中心轴线可以与托座200的中心轴线同轴。
直接在托台210上设置从动旋盘420，并使从动旋盘420与托台210为一体件，可以提高底脚110的结构整体性，增强结构稳定性。
球窝部配置成使滚轮300嵌设于其中时至少一部分凸出于球窝部的底端。滚轮300可以为万向球，例如，钢球，可以沿水平度旋转，使得安装有底脚调节系统10的装置可以灵活地滑移，降低了底脚调节系统10的螺杆410的转动难度，从而可以大大降低安装过程的劳动强度，使得装置的调平过程操作简便，省时省力。
滚轮300凸出于托座200的球窝部底端，并直接抵压于支撑面，螺杆410可以与托座200同步转动，当驱动螺杆410转动时，滚轮300可以水平度旋转，既能降低安装底脚110的螺杆410的转动难度，从而可以大大降低安装过程的劳动强度，又能减少或避免托座200因与支撑面接触而发生磨损，延长底脚调节系统10的使用寿命。
本实施例中，底脚110还可以包括限位板430，固定设置于从动旋盘420的上方，以与托台210限定出同步带的安装空间，提高同步带与从动旋盘420之间配合连接的可靠性。
图5是根据本发明另一实施例的底脚调节系统10中底脚110的示意图。
在另一些可选的实施例中，可以对托座200和滚轮300的结构进行变换，底脚110还可以进一步地包括连接件。托座200可以包括托台210和下翻连轴部230，还可以进一步地包括上翻止转部220。滚轮300可滚动地设置于托台210下方。滚轮300包括沿水平方向延伸的轮轴310和绕轮轴310转动的轮体320。
托台210可以为托座200上的水平板壁部。其中，“水平”是相对于安装底脚110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211。
下翻连轴部230从托台210向下延伸，且具有用于与滚轮300的轮轴310配合的轴孔231，以使滚轮300的轮轴310可转动地连接于托座200。本实施例中，下翻连轴部230可以为托座200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。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300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300的轮轴310的中间区段配合。
上翻止转部220从托台210向上延伸，用于插入安装于底脚调节系统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220从托台210的与从动旋盘420存有间距的部位处向上延伸，这可以防止上翻止转部220阻碍从动旋盘420转动。
从动旋盘420位于光孔211上方。连接件的一端与从动旋盘420固定连接或与从动旋盘420为一体件，另一端穿过光孔211并与光孔211的下周缘配合，以限制从动旋盘420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，从动旋盘420沿其旋转轴线转动时，连接件会阻止从动旋盘420相对于托台210沿竖直方向移动，使得从动旋盘420在竖直方向上不会相对于托台210发生位移。
连接件不与光孔211的下周缘固定连接，可仅使从动旋盘420和螺杆410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。
图6是图5所示的底脚调节系统10中底脚110的部分结构示意图。
连接件可以为卡爪。例如，连接件为下缘周向带有多个外凸卡扣510的中空筒状卡爪。连接件可以从从动旋盘420的底壁向下延伸，穿过光孔211，以与光孔211的下周缘配合。
每个外凸卡扣510在其所处的卡爪的周壁区段之间具有间隙开口，即，外凸卡扣510沿卡爪下缘的周向依次间隙排列。当将卡爪下缘插入光孔211时，卡爪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211。
每个外凸卡扣510的下表面为沿径向向外方向倾斜向上的斜面，这有利于使卡爪下缘平滑地穿过光孔211。其中，“向外”是相对于中空筒状卡爪的实际使用状态而言的。
中空筒状卡爪的中心轴线沿竖直方向延伸。每个外凸卡扣510的上表面为与卡爪的周壁垂直的平面，大致可以为水平面。每个外凸卡扣510的上表面可以与光孔211的孔壁形成卡扣配合。光孔211的孔壁在托台210的下表面形成有下环形凸缘202，以与外凸卡扣510的上表面形成卡扣配合，这有利于避免外凸卡扣510的上表面与托台210的主体板面接触。
且从动旋盘420可以通过一环形垫圈或形成在从动旋盘420的下表面上的环形凸起抵压于托台210的上表面，这可以减小从动旋盘420与托台210上表面的接触面积，有利于降低从动旋盘420转动时的摩擦阻力。环形垫圈可以设置于从动旋盘420下表面与托台210上表面之间。环形凸起可以形成于从动旋盘420的下表面。
图7是根据本发明又一实施例的底脚调节系统10中底脚110的示意图。
在又一些可选的实施例中，调节部400可以为两个，分别为第一调节部400和第二调节部400。第一调节部400的从动旋盘420的外周缘形成有多个第二轮齿，第二调节部400的从动旋盘420的外周缘形成有多个第三轮齿，第二轮齿与传动带150传动啮合，第三轮齿与第二轮齿传动啮合。第一调节部400的螺杆410的螺纹旋向与第二调节部400的螺杆410的螺纹旋向相反，例如第一调节部400的螺杆410的螺纹可以为正牙螺纹，第二调节部400的 螺杆410的螺纹可以为反牙螺纹。
第二轮齿与传动带150传动啮合，这可使第一调节部400的从动旋盘420随主动转轴121转动。第三轮齿与第二轮齿传动啮合，可以使得第二调节部400的从动旋盘420从动地随第一调节部400的从动旋盘420转动。第一调节部400的从动旋盘420的盘径大于第二调节部400的从动旋盘420的盘径。其中，盘径是指圆盘的外周缘所在圆的直径。第一调节部400的从动旋盘420的盘径大于第二调节部400的从动旋盘420的盘径，这便于在第一调节部400的从动旋盘420上布置传动带150，即，传动带150可以套设于第一调节部400的从动旋盘420上，从而直接带动第一调节部400的从动旋盘420转动。第二调节部400的从动旋盘420可以从动地布置在第一调节部400的从动旋盘420的一侧，且位于传动带150的内侧，从而在第一调节部400的从动旋盘420的带动下随之转动。
本实施例的底脚调节系统10，在装置的安装过程中，可以同时调节第一调节部400的螺杆410和第二调节部400的螺杆410旋入对应螺纹孔的深度，这既可以保证装置的调节平稳性，又可以简化底脚调节系统10的调节过程。
由于第二调节部400的从动旋盘420从动地随第一调节部400的从动旋盘420转动，将两个调节部400的螺杆410的螺纹旋向设置为相反，可以保证两个调节部400的螺杆410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400在调节过程中的一致性。
以上实施例的底脚调节系统10尤其适用于嵌入式的冰箱70。图8是根据本发明一个实施例的冰箱70的示意图，图9是图8中B处的局部放大图。
冰箱70的底部设置有至少一个上述任一实施例的底脚调节系统10。且冰箱70的底部开设有螺纹孔，底脚110的螺杆410与螺纹孔螺接。
由于本实施例的冰箱70中底脚调节系统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。
底脚调节系统10可以为一个或多个，例如，可以为两个。主动转轮120和底脚110的相对位置可以根据实际需要进行布置，例如，每个底脚调节系统10的主动转轮120可以设置于冰箱70的底部前侧，每个底脚调节系统10的底脚110可以设置于冰箱70的底部后侧。在安装冰箱70的过程中，尤其在调平的过程中，可以在冰箱70的前侧调节冰箱70后侧的平整度，调平过 程十分简单。
在另一些可选的实施例中，冰箱70的底部前侧可以设置有可滚动的前轮。
图10是根据本发明一个实施例的冰箱70的底板710和底脚调节系统10的示意图。
螺纹孔形成于冰箱70的底板710上。底板710可以直接为冰箱70的箱体的底板710，也可以为在箱体上额外增设的底板710。冰箱70的底板710上形成有从底板710所在板面向上延伸的螺筒，螺筒的内部形成螺纹孔。
本实施例的底脚调节系统10以及具有其的冰箱70，底脚调节系统10包括主动转轮120、传动带150和底脚110。其中，主动转轮120的一部分形成主动转轴121，传动带150套设于主动转轴121的外周。底脚110具有螺杆410和从动旋盘420，螺杆410用于可转动地螺接于装置的底部螺纹孔中，从动旋盘420通过传动带150与主动转轴121传动连接，并且与螺杆410固定连接或与螺杆410为一体件，以带动螺杆410转动。采用本实施例的底脚调节系统10，通过驱动主动转轴121转动，即可间接地驱动螺杆410转动，可以明显降低装置的调平难度，降低装置的安装难度，提高嵌入式的冰箱70的安装效率。
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。
