实用新型内容：
本实用新型所要解决的技术问题是：提供一种结构简单且有效适用于狭小空间内使用的便携式自吸泵。
为了解决上述技术问题，本实用新型是通过以下技术方案实现的：
一种便携式自吸泵，包括泵体、泵盖、橡胶叶轮以及金属转轴，所述泵体内部具有内腔体，泵体的侧面具有连通内腔体的进水口以及出水口，所述进水口与出水口处于同一平面内且两者的轴线之间呈20°-160°设置，外端设置连接水管的螺纹，所述内腔体呈凸轮状结构设计且所述橡胶叶轮置于内腔体内，所述金属橡胶叶轮环套镶嵌在金属转轴的端部，所述金属转轴的另一端穿过泵体一端面中部的轴孔并延伸至泵体外，所述泵体的另一端面设有盖合在端部的泵盖。
作为优选，所述轴孔与金属转轴之间设有套接在金属转轴上的油封和压套，中部的轴孔靠近内腔体的一侧设置有油封室，所述油封套接在压套外部并置于油封室内。
作为优选，所述泵体的进水口和出水口之间设置有一条与油封室相连的凹 槽
作为优选，所述内腔体外侧边缘的泵体上设有密封槽，所述密封槽内设有O型密封圈，所述O型密封圈通过泵盖压紧固定在内腔边缘的泵体上。
作为优选，所述进水口与出水口的轴线之间所呈的角度设置为50°-130°。作
为优选，所述进水口和出水口外端设置有连接水管的螺纹。
作为优选，所述泵体与泵盖接触的一端面上设有多个螺纹孔，所述泵盖上设有多个与螺纹孔配合的通孔，所述泵盖与泵体之间通过螺栓穿过螺纹孔以及通孔可拆卸连接紧固。
作为优选，所述金属转轴的自由端设置为多边形端头。
与现有技术相比，本实用新型的有益之处是：所述便携式自吸泵整体简单，安装制作以及拆卸维护方便，自吸时间短，效率高，且整体结构体积小，占用空间资源小，操作使用方便，因而适合狭小空间作业，实用性高，适合推广应用。
附图说明：
下面结合附图对本实用新型进一步说明：
图1是本实用新型的爆炸结构示意图；
图2是本实用新型的侧面剖视结构示意图；
图3是本实用新型的泵体的结构示意图。
具体实施方式：
下面将对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本实用新型的一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本实用新型保护的范围：
如图1、图2所示的一种便携式自吸泵，包括泵体1、泵盖2、橡胶叶轮3以及金属转轴4，所述泵体内部具有内腔体5，泵体的侧面具有连通内腔体的进水口6以及出水口7，所述进水口与出水口处于同一平面内且两者的轴线之间呈20°-160°设置，优选设置为50°-130°，且为方便连接外部水管，所述进水口和出水口外端设置有连接水管的螺纹，在实际应用中，在所述自吸泵第一次加水时，由于进水口与出水口之间成角度设置，因而第一次使用完后，进水口与出水口与内腔体之间的连接处会存储少量的水，因而下次使用则不用加水，提高了自吸的时间和效率。
所述内腔体呈凸轮状结构设计且所述橡胶叶轮置于内腔体内，当橡胶叶轮在内腔体内转动时，其柔性的叶轮片会折弯变形，叶轮片在这边变形过程中会产生容积变化，因而有效且快速的将水吸入和挤出，实现自吸泵的自吸过程。
所述金属橡胶叶轮环套镶嵌在金属转轴的端部，所述金属转轴的另一端穿过泵体一端面中部的轴孔并延伸至泵体外，在本实施例中，为提高金属转轴与泵体之间的密封效果，所述轴孔与金属转轴之间设有套接在金属转轴上的油封8和压套9，中部的轴孔靠近内腔体的一侧设置有油封室14，所述油封套接在压套外部并置于油封室内，具体地，所述轴孔设置为台阶孔，靠近内腔体一侧的孔为大直径孔也即油封室，所述油封套接在金属转轴上且置于油封室内，所述压套设置为T型且中部设有套接在金属转轴上的通孔，所述压套插接在油封的环形槽内，因而有效提高泵体的密封效果，避免漏水的情况发生。
如图3所示，进一步地，所述泵体的进水口和出水口之间设置有一条与油封室14相连的凹槽15，所述凹槽内凹于内腔体的侧壁，内腔体内的部分流体会进入凹槽继而进入油封室内，继而提高油封的润滑和冷却效果。
所述泵体的另一端面设有盖合在端部的泵盖，继而将泵体的内腔体形成完 整而密封的自吸腔，为提高自吸腔的密封效果，所述内腔体外侧边缘的泵体上设有密封槽11，所述密封槽内设有O型密封圈12，所述O型密封圈通过泵盖压紧固定在内腔边缘的泵体上。
另外，为提高整体结构的稳固性，且为方便拆卸维护，所述泵体与泵盖接触的一端面上设有多个螺纹孔13，所述泵盖上设有多个与螺纹孔配合的通孔，所述泵盖与泵体之间通过螺栓穿过螺纹孔以及通孔可拆卸连接紧固。
在实际应用中，所述金属转轴的自由端可以设置为多边形端头，因而在实际使用中，可以直接通过电动手枪钻或者其它具有多边形电动转头的小型便捷式设备，即可与金属转轴的多边形端头连接，并带动金属转轴转动，继而为自吸泵提供动力，因而使用方便。
上述便携式自吸泵整体简单，安装制作以及拆卸维护方便，自吸时间短，效率高，且整体结构体积小，占用空间资源小，操作使用方便，因而适合狭小空间作业，实用性高。
需要强调的是：以上仅是本实用新型的较佳实施例而已，并非对本实用新型作任何形式上的限制，凡是依据本实用新型的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本实用新型技术方案的范围内。
