背景技术
红外线水平仪、激光投线仪、激光测距仪等广泛应用于建筑施工、工程监测、工程装饰及家具装修领域等。激光投线仪，又被称作是激光标线仪或激光水准仪，激光投线仪是利用半导体激光器经过扩束而成的一条或多条高亮度的激光线，通过激光线投射在物体上而产生投线，使用者可根据该投线对物体进行切割、对齐或其他用处。激光测距仪，是利用调制激光的某个参数实现对目标的距离测量的仪器。按照测距方法分为相位法测距仪和脉冲法测距仪，脉冲式激光测距仪是在工作时向目标射出一束或一序列短暂的脉冲激光束，由光电元件接收目标反射的激光束，计时器测定激光束从发射到接收的时间，计算出从观测者到目标的距离。相位法激光测距仪是利用检测发射光和反射光在空间中传播时发生的相位差来检测距离的。激光测距仪重量轻、体积小、操作简单速度快而准确，其误差仅为其它光学测距仪的五分之一到数百分之一。目前，在现有的建筑施工场景中，通常要将投线仪与测距仪组合使用，分别操作投线仪和测距仪以实现投线和测距，但是，由于两种仪器各种占有一定体积，在携带和摆放过程中均会产生不便。

参考图3，为符合本发明一优选实施例的投线仪的内部结构示意图。所述投线仪11包括第一上壳、第一下壳、第一激光模块111、水准模块112、第一按键模块113、第一电源模块114；所述第一激光模块111，位于所述第一下壳的投线仪出光面一端，面向所述投线仪出光面设置；所述水准模块112，位于所述第一下壳的所述投线仪出光面的相对端，面向所述第一上壳设置；第一按键模块113位于投线仪11的侧面，当然，也可以设置于投线仪外壳的任意一面；第一电源模块114位于第一激光模块111、水准模块112与第一下壳之间。
参考图4-5，为符合本发明一优选实施例的测距仪的内部结构示意图。所述测距仪包括第二上壳、第二下壳、支架、第二激光模块121、测距模块122、数显模块123、第二按键模块、第二电源模块124；所述第二激光模块121，位于所述支架的测距仪出光面一端，面向所述测距仪出光面设置；所述测距模块122，位于所述支架的所述第二激光模块121之后，在所述第二 激光模块121、第二电源模块124之间；所述数显模块123，位于所述第二上壳；第二按键模块可以设置于测距仪外壳的任意一面，第二电源模块124位于支架的测距模块122之后。
首先，基于上述配置，本发明提供的投线仪11与测距仪12在尺寸、体积、重量等方面均比市面上的普通产品要小很多，可以在口袋中携带，非常适合在民用建筑施工场景中使用。而且，本发明提供的投线仪11与测距仪12均呈立方体(长方体)结构，不仅便于包装，而且更加方便携带。
其次，所述小型测距仪12与小型投线仪11均可单独使用，实现其基本功能。所述测距仪12体积小，重量轻，集成度高，速度快，容易操作，对人眼安全，可在日常生产、生活中得到广泛应用，例如用于野外打猎、高尔夫球洞测距，或者用于室内尺度丈量等。
更重要的是，所述小型测距仪12与小型投线仪11可组合使用，可在投线的同时实现测距，达到意想不到的便利效果。同样的，本发明提供的投线仪11与测距仪12均呈立方体(长方体)结构，这种结构更加方便安装，便于搭配使用。且投线仪11与测距仪12在尺寸上互相配合，例如，投线仪11的上下底面的宽度与测距仪12上下底面的宽度相当，投线仪11与测距仪12上下叠加设置；在投线仪11上设置限位装置，将投线仪11、测距仪12叠加放置，投线仪11上的限位装置将测距仪12固定在投线仪11的一侧，或者，在测距仪12上设置限位装置，将投线仪11、测距仪12叠加放置，测距仪12上的限位装置将投线仪11固定在测距仪12的一侧。
参考图1，在投线仪11与测距仪12的第一种组合使用方式下，一个仪器可以放置在另一个仪器的上方，且在外壳上有特定的限位装置确保两台仪器的平行放置，使得激光发射方向一致。这样，在工作时，可以在投线仪11向墙面投线的同时测距仪12测得工作点到墙面的距离。
在一优选实施例中，限位装置包括位于所述投线仪11两侧面边缘的凸起条13，类似于两段高出的边框，所述凸起条13之间的距离与所述测距仪12沿其径向的宽度相当，使所述测距仪12卡入所述凸起条13间。这样，可 以很快地将投线仪11摆放到准确的位置，且放好后刚好处于凸起条13内而不易再产生移动。
在该实施例中，投线仪11与测距仪12均呈立方体(长方体)结构，两者水平放置且上下叠加、平行设置，测距仪12放置在投线仪11上方。投线仪11与测距仪12在尺寸上互相配合，投线仪11的上下底面的宽度略大于测距仪12上下底面的宽度，并且在投线仪11两侧面的边缘上设置凸起条13，凸起条13之间的距离与测距仪12沿其径向的宽度相当，从而使得测距仪12卡入所述凸起条13间而不易再产生径向移动。
在一优选实施例中，可以在沿着投线仪11的两侧面的边缘轮廓全包围设置两条凸起条13，并且凸起条13在长方体的八个转角处均进行圆角处理。
在另一优选实施例中，凸起条13可以仅仅在沿着投线仪11的两侧面的轴向边缘轮廓设置，长度可以刚好与轴向边缘轮廓相当，并在转角处进行圆角处理。当然，凸起条13的设置不限于上述两种，还可以沿着轴向边缘轮廓间隔设置，例如设置为均匀分布的若干小段，也可以仅仅沿两侧面的轴向边缘设置一小段。在上述在投线仪11两侧面的边缘设置凸起条13、将测距仪12卡入凸起条13以限制测距仪12的径向位移的基础上，还可以在投线仪11前后面边缘设置凸起条13，凸起条13的设置同样可以参照上述的几种形式，以此限制测距仪12在轴向上的移动。
在一优选实施例中，在上述凸起条13的基础上，还可以在投线仪11两侧面轴向边缘设置的上述凸起条13上向内相向设置轨槽，并在测距仪12的轴向边缘向外设置与上述轨槽相互配合的导轨，这样使得测距仪12沿所述轨槽滑入凸起条13之间。
可以理解的是，投线仪11、测距仪12的上下位置不限于上述位置，也可以设置为投线仪11的上下底面的宽度略小于测距仪12上下底面的宽度时，将投线仪11放置在测距仪12的上方，将投线仪11卡入测距仪12的限位装置中，限位装置的形状、位置、结构同样可参照上述的几种形式，不在赘述。
参考图2，在投线仪11与测距仪12的第二种组合使用方式下，一个仪器可以放置在另一个仪器的上方，且在外壳设置限位装置确保两台仪器的垂直放置，使得激光发射方向相互垂直，这样，在工作时，可以在向墙面投线的同时测得工作点到左右墙面的距离，例如使用者需要在目标墙面上每隔若干距离进行点或线的投影作参考，便可以在这种组合方式下很快完成工作。
在一优选实施例中，限位装置包括位于所述投线仪11两侧面边缘的带缺口14的凸起条13，所述缺口14宽度与所述测距仪12沿其轴向的长度相当，将所述测距仪12容纳其中，使得所述测距仪12、投线仪11垂直放置。这样，同样可以很快地将投线仪11摆放到准确的位置且放好后刚好处于凸起条13内而不易再产生移动。
在该实施例中，投线仪11与测距仪12均呈立方体(长方体)结构，测距仪12竖直放置，投线仪11水平放置，两者上下叠加且垂直放置，测距仪12放置在投线仪11上方。投线仪11与测距仪12在尺寸上互相配合，测距仪12的宽度小于投线仪11的轴向长度，并且在投线仪11两侧面的边缘上设置带缺口14的凸起条13，凸起条13的缺口14之间的距离与测距仪12的高度相当，从而使得测距仪12卡入所述凸起条13的缺口14之间而不易再产生移动。
同样的，凸起条13的设置可以参照上述的沿着投线仪11的两侧面的边缘轮廓全包围设置、仅仅在沿着投线仪11的两侧面的轴向边缘轮廓设置、还可以沿着轴向边缘轮廓间隔设置，例如设置为均匀分布的若干小段，也可以仅仅沿两侧面的轴向边缘设置一小段，只要使得凸起条13缺口14的宽度等于测距仪12的高度即可。
在一优选实施例中，所述缺口14方向平行于所述投线仪11径向设置。这样，测距仪12竖直放置，投线仪11水平放置，两者上下叠加垂直设置，使其激光发射方向相互垂直。在另一优选实施例中，所述缺口14方向与所述投线仪11径向呈一夹角设置。这样，测距仪12竖直放置，投线仪11水平放置，两者上下叠加呈一夹角设置，使其激光发射方向同样呈一夹角。
此外，还可以设置为，投线仪11、测距仪12水平放置，两者上下叠加但相互交错设置，使其激光发射方向呈一夹角。在投线仪11的两侧面边缘设置带缺口14的凸起条13，使得凸起条13缺口14的宽度与测距仪12的宽度相等，且缺口14的方向与所述投线仪11径向呈一夹角设置，将测距仪12容纳在缺口14之中。
在一优选实施例中，所述测量工具10还包括底座，所述投线仪11与所述底座通过螺纹可调节连接。在投线仪11的底部设有螺纹孔，与底座螺纹连接，在工作平面达不到水平的情况下，可以搭配底座进行使用，调节工作面至水平。
在一优选实施例中，所述投线仪11、测距仪12采用可充电池，在所述投线仪11、测距仪12上设有充电接口。充电接口可以是USB接口，可以设置在投线仪11、测距仪12的激光发射面的相对面。
应当注意的是，本发明的实施例有较佳的实施性，且并非对本发明作任何形式的限制，任何熟悉该领域的技术人员可能利用上述揭示的技术内容变更或修饰为等同的有效实施例，但凡未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何修改或等同变化及修饰，均仍属于本发明技术方案的范围内。
