Description
本实用新型涉及光学仪器领域，尤其涉及一种电子测距仪。
电子测距仪是一种常见的测绘仪器，也被成为全站型电子测距仪(Electronic Total Station)，是集水平角、垂直角、距离(斜距、平距)、高差测量功能于一体的测绘仪器，因其独立完成该测量站上全部测量工作，也被称为全站仪。电子测距仪广泛用于地面大型建筑和地下隧道施工等精密工程测量或变形监测领域，其工作场合基本是在户外。为了保证仪器在下雨、下雪等恶劣天气条件下正常工作不被损坏，电子测距仪常常具有防水功能，然而，电子测距仪具有可以灵活旋转的结构，针对这一结构做好防水措施是业界的难题。

然而，现有技术中的电子测距仪的防水结构仍存在问题，即V形橡胶圈105与支架外壳102之间并不能保证完全密封，由于测距头101与支架为分离式的部件，为了便于组装，会在支架外壳102的内侧设有安装槽，以便将测距头101装入，V形橡胶圈105与支架外壳102之间不可避免地出现缝隙，导致漏水。
为了解决上述问题，需要一种新式的电子测距仪，具有更好的防水效果。

以下结合附图与具体实施例进一步阐述本实用新型的优点。
参阅图2，为符合本实用新型一优选实施例中电子测距仪的正面结构示意图，所述电子测距仪包括：
-转盘211
所述转盘211设于所述电子测距仪的底部，水平放置，沿一纵轴旋转。所述转盘211支撑整个电子测距仪，允许安装于所述转盘211上的部件随着一起转动，以实现对水平面上不同位置进行检测。
-主机212
所述主机212安装于所述转盘211上，用于对各种信号进行处理并计算得到所检测的参数。所述主机212上可设有显示屏及输入按钮，向外输出检测结果和设置界面，还能接收外部输入各类参数、调节姿态及工作模式。
-支撑臂202
所述支撑臂202有一对，其底部与所述主机212连接，所述支撑臂202用于支撑下文所述的测距单元201，设于所述测距单元201两侧。所述支撑臂202的顶部由一横梁相连接，一方面与主机212一起固定所述支撑臂202，另一方面便于人员握持，从而携带所述电子测距仪。
-测距单元201
所述测距单元201通过一水平方向的横轴203与所述支撑臂202连接，并沿所述横203旋转。所述测距单元201上设有物镜209及粗瞄器210，用于光学测距及瞄准。所述横轴203内设有电气线路，连接所述测距单元201与所述主机212。所述测距单元201还可以是左右对称结构，其两侧各设有密封结构，实现与所述支撑臂202之间的密封，防止外部的水进入横轴203内导致电气故障。
参阅图3，为符合本实用新型一优选实施例中电子测距仪的局部剖面结构示意图，重点展示了所述测距单元201与支撑臂202之间的连接结构。所述支撑臂202的外壳204朝向所述测距单元201的一面设有一安装孔，从图3中可以看出外壳204被分成了上下两部分，两部分之间即安装孔。
所述横轴203伸入所述安装孔内并与所述外壳204内的轴承205连接，所述轴承205 自所述安装孔凸出于所述外壳204，所述轴承205的截面为L形，所述L形的弯折处卡在所述安装孔的边缘，从而实现对轴承205的限位固定。可以看出，所述外壳204的左侧为内侧，右侧为外侧，所述轴承205从所述外壳204的内侧向外侧凸出，这是与现有技术的区别点，图1中的轴承104完全处于所述支架外壳102内侧，本实施例中轴承205朝向所述外壳204外侧延伸后于所述支撑臂202与所述测距单元201之间形成一环绕所述横轴203一周的凸台206。
为了实现测距单元201与支撑臂202之间的密封，所述电子测距仪还包括：
-V形密封圈207
所述V形密封圈207包括第一侧壁2071及第二侧壁2072，所述第一侧壁2071安装于所述凸台206上，所述第二侧壁2072与所述测距单元201朝向所述支撑臂202的平滑的侧面紧密接触。本实用新型与现有技术最大的区别在于V形密封圈207安装在支撑臂202一侧的凸台206上，通过所述第二侧壁2072与所述测距单元201的侧面紧密接触，而所述测距单元201的侧面可以做成平滑的接触面，没有凹槽，从而实现良好的密封效果。
-O形密封圈208
所述O形密封圈208设于所述安装孔与所述轴承205之间，封闭所述安装孔与所述轴承205之间的缝隙。由于所述V形密封圈207安装在所述凸台206上，不与所述外壳204的侧面直接接触，故还需其他结构来封闭所述安装孔与所述轴承205之间的缝隙，故采用O形密封圈208。
所述外壳204、O形密封圈208、轴承205、V形密封圈207及测距单元201形成一密封结构，将所述横轴203密封在所述密封结构内，防止外部的水与所述横轴203接触，保障其内部的电气线路不被水接触造成短路损坏，延长所述电子测距仪的使用寿命。
进一步地，所述第一侧壁侧2071向加厚以形成截面为梯形或矩形的安装部。所述凸台206的边缘向内凹陷形成一与所述安装部相配合的沟槽；所述安装部安装于所述沟槽内。本改进实施例中，选用的V形密封圈207并不是标准的V字形，而是一侧较厚一侧较薄的不对称截面，较厚的一侧为所述第一侧壁2071，适用于固定安装；较薄的一侧为所述第二侧壁2072，具有一定弹性，适用于与外部紧密接触以密封。
作为所述电子测距仪的进一步改进，所述O形密封圈208及V形密封圈207为橡胶材质。
应当注意的是，本实用新型的实施例有较佳的实施性，且并非对本实用新型作任何形式的限制，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，但凡未脱离本实用新型技术方案的内容，依据本实用新型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，均仍属于本实用新型技术方案的范围内。
