Description
本申请要求2018年04月08日在中国国家知识产权局提交的申请号为201810304704.6、发明名称为“脚轮安装组件和空气调节设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
本发明涉及空调技术领域，具体而言，涉及一种脚轮安装组件和一种空气调节设备。
目前市场上脚轮形式各样，用于空气调节设备上的脚轮组件装配方式主要是通过螺钉和螺栓等紧固件与底组件连接，该装配方式虽然可靠牢固，但零件数量多，生产和装配效率低下，成本较高。
发明内容
本发明旨在至少解决现有技术或相关技术中存在的技术问题之一。
有鉴于此，本发明的一个目的在于提供一种脚轮安装组件。
本发明的另一个目的在于提供一种空气调节设备。
为了实现上述目的，本发明第一方面的技术方案提供了一种脚轮安装组件，包括：底盘；脚轮组件，脚轮组件包括：脚轮本体；连接杆，连接杆的一端与底盘固定连接，且连接杆的另一端伸入脚轮本体的安装孔内可转动地固定；其中，连接杆伸入安装孔的一端设有周向的定位槽，安装孔内壁设有沿径向向安装孔的轴线凸出且与定位槽对应的定位圈，定位圈的最小直径大于定位槽的最大直径。
在该技术方案中，连接杆与底盘固定连接，脚轮本体上设有安装孔，通过连接杆伸入脚轮本体上的安装孔实现脚轮组件与底盘的连接，这样的 安装快速方便，相对于现有技术中连接杆与脚轮固定的方式，减少了零件数量，结构简单，且由于底盘和连接杆一般都是轴对称部件，将这两者进行固定连接，更有利于相互定位和生产，从而提高了生产效率和装配效率。
更具体地，由于连接杆和底盘一般都是轴对称部件，连接杆的一端与底盘固定连接，便于生产和装配；同时，脚轮安装组件使用时，脚轮本体需要随着设备的移动而转动，并不需要连接杆和底盘进行转动，因此，将连接杆和底盘固定连接在一起，有利于提高脚轮安装组件在使用中的稳定性，进而提高产品的安全性；连接杆的另一端伸入脚轮本体的安装孔内可转动地固定，且连接杆伸入安装孔的一端设有周向的定位槽，安装孔的内壁设有沿径向向安装孔的轴线凸出且与定位槽对应的定位圈，定位圈的最小直径大于定位槽的最大直径，这样的结构，在连接杆插入安装孔后，当定位槽到达定位圈的位置时，可以快速定位，便于连接杆快速与脚轮本体安装连接，且不易脱落，相对于现有技术中，在定位槽上设置卡簧、弹性件的方式，减少了零件数量，简化了结构，提高了生产和装配效率。
可以理解地，连接杆与底盘的固定连接方式，可以是一体成型，也可以是卡接、或过盈配合的插接，或者其他固定方式。
在上述技术方案中，进一步地，连接杆靠近底盘的一端沿径向向外凸起形成环形限位部，环形限位部的一端与底盘的底壁相抵。
在该技术方案中，连接杆靠底盘的一端设有与底盘的底壁相抵靠的环形限位部，使连接杆不能完全伸入底盘内，由此，设备的一部分重量可以由环形限位部和底盘底壁共同承担，而环形限位部是沿连接杆的径向向外凸出形成的，因此环形限位部的面积大于连接杆的横截面积，设备的一部分重量被均分在了较大面积的环形限位部和底盘的底壁上，减小了底盘局部受力过大导致破坏的可能，延长了底盘的使用寿命，同时，环形限位部的设置，还使底盘容纳连接杆的空间可以是一个通孔，减少了连接杆完全插入通孔内导致脚轮和底盘抵接以致转动不顺畅的可能，从而可以简化结构，提高生产和装配效率。
在上述技术方案中，进一步地，环形限位部远离底盘的一端与安装孔 的外端面之间存在间隙。
在该技术方案中，在环形限位部与安装孔外端面之间设置间隙，使脚轮本体与环形限位部不能抵靠在一起，从而脚轮本体不会与环形限位部接触，进而不会在转动时受到来自环形限位部的摩擦阻力，从而在设备移动时，脚轮本体可以顺畅地进行转动。
在上述技术方案中，进一步地，连接杆伸入安装孔的伸入部自环形限位部远离底盘的一端至定位槽的上端的部分的直径相同，这样的结构简单，便于生产，同时，在相同的直径使伸入部与安装孔内壁之间能够保持相同的间隙，从而具有更好的径向平衡性能，提高了脚轮安装组件的平衡性，不易晃动，进而减少因晃动导致安装孔破裂的可能，提高了脚轮安装组件使用的稳定性。
在上述技术方案中，进一步地，连接杆远离底盘的一端构造成设有倒角的导向端，定位槽设于导向端与环形限位部之间。
在该技术方案中，通过设有倒角的导向端，连接杆可以快速与安装孔定位并插入安装孔内；定位槽位于导向段与环形限位部之间，使连接杆插入安装孔后，定位槽可以同时进入安装孔并到达定位圈所在位置，实现连接杆在安装孔内的定位，从而降低了装配难度，提高了装配效率。
在上述技术方案中，进一步地，安装孔的直径与伸入部的直径的差值大于0.05mm，其中，伸入部的直径小于安装孔的直径。
在该技术方案中，将安装孔的直径设置为大于连接杆的伸入部的直径，使连接杆与安装孔为间隙配合，便于连接杆的安装和拆卸，也有利于提高脚轮本体转动的舒畅度，同时，将差值限定为大于0.05mm，避免了差值过小导致精度难以达到而生产困难的可能。
在上述技术方案中，进一步地，伸入部的直径与定位圈的最小直径的差值大于0.05mm，其中，定位圈的最小直径小于伸入部的直径。
在该技术方案中，将定位圈的最小直接设置为小于伸入部的直径，使定位圈与伸入部为过盈配合，从而在连接杆插入安装孔，并使定位槽到达定位圈的位置后，由于伸入部的直径大于定位圈的最小直径，使连接板难以再移动，实现定位。
具体地，在连接杆插入安装孔后，先由具有倒角的导向端接触到定位圈，由于倒角的设置，使导向端能够顺利通过定位圈，并使定位槽到达定位圈的位置处，与定位圈间隙配合，当连接杆再继续插入时，定位槽的上端直径与伸入部的直径相同，即大于定位圈的直径，从而不能再移动，实现连接杆在安装孔内的定位。
这样的定位结构，相较在定位槽上设置卡簧、弹性件等现有技术，节省了零件数量，减少了生产工序，且结构简单，安装快速便捷。
在上述技术方案中，进一步地，定位圈的最小直径与定位槽的最大直径的差值大于0.1mm。
在该技术方案中，定位圈的最小直径比定位槽的最大直径大0.1mm，使定位圈与定位槽为间隙配合，有利于提高脚轮本体转动的舒畅度。
在上述任一项技术方案中，可选地，安装孔为盲孔，使盲孔和定位圈一同对连接杆起到限位的作用，可以减少连接杆插入孔内太深，导致环形限位部与脚轮本体抵接，最终导致脚轮本体旋转困难的可能；同时，安装孔设为盲孔，还可以避免地面的水浸入脚轮本体内，提高脚轮使用的可靠性。
本发明第二方面的技术方案提供了一种空气调节设备，包括：壳体；和上述第一方面中的任一项技术方案的脚轮安装组件，脚轮安装组件设于壳体的底板上。
在该技术方案中，通过采用上述任一项技术方案的脚轮安装组件，从而具有了上述全部技术方案的有益效果，在此不再赘述。
其中，需要说明的是，空气调节设备可以为除湿机、移动空调、净化器或其它的底部可安装上述脚轮的家电设备。

为了可以更清楚地理解本发明的上述目的、特征和优点，下面结合附图和具体实施方式对本发明进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本发明，但是，本发明还可以采用其他不同于在此描述的其他方式来实施，因此，本发明的保护范围并不受下面公开的具体实施例的限制。
下面参照图1至图4描述根据本发明的一些实施例。
如图1至图4所示，根据本发明提出的一个实施例的脚轮安装组件，包括，底盘10和脚轮组件，脚轮组件包括：脚轮本体12和连接杆14，连接杆14的一端与底盘10通过注塑一体成型，安装孔120的直径D1大于连接杆14直径d1，使连接杆14可插入安装孔120内；连接杆14的另一端伸入脚轮本体12的安装孔120内可转动地固定，使脚轮本体12能绕连接杆14的中心轴进行圆周旋转。
如图3所示，进一步地，底盘10包括同轴相互套接的内圆筒和外圆筒，内圆筒与外圆筒之间设有以轴线为中心呈放射状的多条加强筋，连接杆14设于内圆筒内，通过多条加强筋，可以提高底盘10的强度，减少其在周向受力时被撕裂。
如图2与图3、图4所示，连接杆14伸入安装孔120的一端的端部设有倒角，构造成导向端140；连接杆14靠近底盘10的一端沿径向向外凸起形成环形限位部144，环形限位部144的一端与底盘10的底壁相 抵，以分散底盘10的受力，减少其局部受力过大的可能；在环形限位部144与导向端140之间设有周向的定位槽142，且定位槽142更靠近导向端140；安装孔120内壁设有沿径向向安装孔120的轴线凸出且与定位槽142对应的定位圈122，定位圈122的最小直径D2大于定位槽142的最大直径d2，以形成间隙配合，使脚轮本体12能够顺畅地旋转；优选地，定位圈122的最小直径D2比定位槽142的最大直径d2大0.1mm。
具体地，连接杆14伸入安装孔120内的伸入部自环形限位部144远离底盘10的一端至定位槽142的上端的部分的直径相同，且该伸入部的直径d1小于安装孔120的直径D1，以使伸入部与安装孔120形成间隙配合，使脚轮本体12能够顺畅地旋转；还使伸入部与安装孔120内壁之间能够保持相同的间隙，提高脚轮安装组件的平衡性，减少其晃动；优选地，伸入部的直径d1比安装孔120的直径D1小0.05mm。
进一步地，伸入部的直径d1大于定位圈122的最小直径D2，使定位槽142进入到定位圈122的位置后，伸入部能够受到定位圈122的阻挡而停止移动；优选地，伸入部的直径d1比定位圈122的最小直径D2大0.05mm。
通过上述结构，连接杆14在插入安装孔120时，可以利用导向端140快速与安装孔120定位，并在通过定位圈122时，通过导向端140的倒角挤压定位圈122，使定位槽142到达定位圈122的位置，此时，定位槽142的最大直径d2小于定位圈122的最小直径D2，两者为间隙配合，而伸入部的直径d1大于定位圈122的最小直径D2，使伸入部难以通过定位圈122，从而实现连接杆14在安装孔120内的定位。
可以理解地，在非工作状态时，定位槽142上下两部分端面的直径为伸入部的直径d1，都大于定位圈122的直径D2，从而使脚轮本体12难以从连接杆14上脱落下来；工作状态时，在重力作用下，连接杆14有继续向安装孔120深处移动的趋势，由于伸入部的直径d1大于定位圈122的最小直径D2，使连接杆14的伸入部难以通过定位圈122而紧贴定位圈122，使脚轮本体12不会上下移动，提高了脚轮安装组件的稳定性。
更进一步地，安装孔120被设置为盲孔，这样，盲孔可以与定位圈 122一起阻挡连接杆14向下的运动，或者在定位圈122失效时，盲孔独自阻挡连接杆14向下的运动，提高了脚轮安装组件的稳定性，同时，盲孔的设计，还可以减少地面的水浸入到脚轮本体12中的可能。
如图2所示，环形限位部144与安装孔120的外端面之间具有间隙，以使脚轮本体12与环形限位部144不能抵靠在一起，从而在设备移动时，脚轮本体12可以顺畅地进行转动。
可以理解地，本实施例中的连接杆14与脚轮本体12的转动连接，通过轴承实现，即在安装孔120内固设有轴承，连接杆14通过轴承与安装孔120相连。
可选地，连接杆14与底盘10通过卡接固定，或者过盈配合而固定。
