具体实施方式
在实施例的描述中，除非另有明确的规定和限定，术语“相连”、“连接”、“固定”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。
下面结合附图并通过具体实施方式来说明本公开的技术方案。在不冲突的情况下，以下实施例以及实施例中的技术特征可以相互任意组合。
如图1至5所示，本实施例提供一种水泵，包括泵体1、带有进水口21和出水口22的泵房2以及泵座3，泵座3内设置呈圆形的并贯穿泵座3的安装孔31，泵体1的一端设置有与安装孔31套接的呈环形的安装台4，当泵体1一端设置的安装台4插入到安装孔31内时，泵体1可绕安装孔31的轴线相对于泵座3转动，泵房2设置在泵座3远离泵体1的一侧并与泵体1连接。通过在泵体1上设置与泵座3的安装孔31套接的安装台4，使泵体1可相对于泵座3转 动，使出水口22的位置和方向可以在使用中进行调节，方便出水口22与管道连接。在泵体1和泵座3上进行结构更改，使得水泵的结构简单，简化了泵体1与泵座3之间的拆装，降低了生产和运行成本。
在本实施例中，泵房2可以通过螺钉与泵体1可拆卸连接。
在一个可选的实施例中，如图1和2所示，安装台4的外径小于泵体1的直径，即安装台4与泵体1之间形成有限位面，当安装台4插入至泵座3的安装孔31内时，限位面与泵座3靠近泵体1的一端的端面抵接。通过将安装台4的外径设置为小于泵体1的直径，可以利用两者之间形成的限位面与泵房2将泵座3夹设。
在一个可选的实施例中，如图3所示，安装台4的外径大于泵体1的直径，在安装孔31的内壁并沿其轴线方向设置两个呈圆环形的挡板32，挡板32的内孔直径小于安装台4的外径，两个挡板32之间的间距大于安装台4沿轴线方向的宽度。通过将安装台4的外径设置为大于泵体1的直径，并对应在安装孔31的内壁上设置有由两个间隔的呈圆环形的挡板32构成的限位槽，当安装台4插入至安装孔31内时，可以通过此限位槽对安装台4的位置进行限定，防止安装台4沿轴线方向移动。
在一实施例中，安装台4与泵座3之间还可以设置用于限制泵体1的旋转角度的限位部件。
在一个可选的实施例中，限位部件包括一个或多个沿安装孔31的周向环形设在安装孔31的内壁上的限位凸起，以及在所述安装台的外周表面至少设置一个可与所述限位凸起卡接的限位凹槽。参照图4，限位部件包括3个沿安装孔31的周向环形设在安装孔31的内壁上的限位凸起33，在安装台4的外周表面设置三个可与限位凸起33卡接的限位凹槽41。当安装台4插入至安装孔31内时，由于挤压作用安装台4被紧紧的卡设在安装孔31的限位凸起33内，当安装台4旋转至一定角度时，一个限位凸起33与安装台4外周表面的限位凹槽41卡接，此时，由于卡接作用，安装台4的旋转受到阻挡，进而泵体1不能相对于泵座3自由旋转，当需要调整安装台角度时，可以旋转泵体1。旋转力克服安装台4与限位凸起33的摩擦力以及限位凸起33与限位凹槽41的摩擦力，使限位凸起33脱离限位凹槽41，可再次实现安装台角度调整。一个或多个限位凸起33形成的环形安装面的直径与安装台4的外径的差不大于。安装台4在施加外 力卡入到安装孔31内时，若两者的差太大，将很难实现泵体的转动。如果一个或多个限位凸起33形成的环形安装面的直径大于安装台4的外径，安装台4可以在安装孔31内转动，但是无法实现转动到指定角度后对此角度下的安装台4与泵座3的位置进行固定。
可选的，限位部件包括一个或多个沿安装台4的周向环形设在安装台4的外周表面的限位凸起，在安装孔31内沿其周向至少设置一个可与限位凸起卡接的限位凹槽。
在一个可选的实施例中，如图4所示，限位部件包括限位螺钉34和与其配合的限位螺纹孔36，在泵座3上至少开设一个限位螺纹孔36，限位螺纹孔36沿安装孔31的径向延伸并与安装孔31连通，限位螺钉34的第一端设置在泵座3外，限位螺钉34的第二端螺纹旋入限位螺纹孔36内并选择性抵接安装台4的外周表面。
在一个可选的实施例中，参照图5和6，限位部件包括设置在泵座3上的第一螺纹孔35，第一螺纹孔35沿安装孔31的径向延伸并与安装孔31连通，在安装台4的外周环形设置多个与第一螺纹孔35相对应的第二螺纹孔42，限位部件还包括限位螺钉34，限位螺钉34的第一端设置在泵座3外，限位螺钉34的第二端穿过第一螺纹孔35选择性旋入第二螺纹孔42内。通过设置螺纹孔和限位螺钉34的结构，当安装台4与泵座3的旋转位置一定时，且第一螺纹孔35与第二螺纹孔42相对时，可利用限位螺钉34通过第一螺纹孔35和第二螺纹孔42将安装台4与泵座3的相对位置进行固定，当需要对出水口22的位置进行调节时，只需要旋出此限位螺钉34，并旋转泵体1，使安装台4与泵座3发生相对旋转即可。
在一个可选的实施例中，参见图7，限位部件包括环形开设在泵座3上的定位槽37，定位槽37与安装孔31连通，在安装台4上设置定位螺纹孔38，定位螺纹孔38内螺纹旋接有定位螺杆39，定位螺杆39远离安装台4的一端贯穿定位槽37并与位于泵座3上的定位螺母310螺纹旋接。安装时，可以将泵体1一端的安装台4插入至安装孔31内，将定位螺杆39穿过泵座3上的定位槽37螺纹旋接在定位螺纹孔38内，旋转泵体1，使安装台4与泵座3之间相对旋转，当旋转角度为需要的角度时，将定位螺母310旋拧在定位螺杆39上，利用定位螺母310与定位螺杆39的夹紧力，将泵座3与安装台4的位置固定，当需要再 次调整出水口22的位置时，可以将定位螺母310拧松，可使泵座3与安装台4之间的限位部件解除限位动作，泵体1可再次带动安装台4相对于泵座3旋转。
可选的，定位螺杆的直径小于定位槽沿安装孔轴线方向的宽度，定位螺母的宽度大于定位槽沿安装孔轴线方向的宽度。
在本说明书的描述中，术语“第一”、“第二”仅用于描述，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。
