Description

一种等高线演示装置
技术领域
本发明涉及科普教育技术领域，尤其涉及一种等高线演示装置。
背景技术
等高线指的是地形图上高程相等的各点所连成的闭合曲线，在中学学习中，等高线是难点之一。针对这一问题，已经出现了较多的等高线演示器，如公开号CN202013688U，CN203616940U和 CN204066598U的专利文献，这些专利中涉及到的等高线演示装置，存在结构复杂，演示整体效果不佳等问题。
发明内容
本发明的目的在于克服现有技术中采用透明塑料板来演示等高线，存在整体演示效果不佳的问题，而提供的一种利用光束来显示等高线的演示装置。
为解决上述技术问题，本发明采取如下技术方案：
一种等高线演示装置，包括箱体，在所述的箱体内部设有圆柱形凹槽，在所述的圆柱形凹槽的内壁设有多个平行的缝隙，在所述圆柱形凹槽的外侧设有激光器装置，所述的激光器装置包括支架、激光笔、分光镜和一字镜片，镜片固定架通过转轴按照直线阵列分布在所述支架上，所述的分光镜和一字镜片安装在所述的镜片固定架上，所述的激光笔通过激光座固定在所述的支架上。
与现有技术相比，本发明的有益效果为：
本发明一种等高线演示装置，通过激光束在物体表面显示出等高线，利用统一平面上的光线能够在任一物体上显示等高线，简单明了，有助于人们对等高线的理解和学习。
附图说明
图1为本发明主视结构示意图；
图2为本发明侧视结构示意图；
图3为本发明I处局部放大结构示意图；
图4为本发明俯视结构示意图。
具体实施方式
参见附图1-4所示，一种等高线演示装置，包括箱体1，在所述的箱体1内部设有圆柱形凹槽2，在所述的圆柱形凹槽2的内壁设有多个呈现平行的缝隙2-1，在所述圆柱形凹槽2的外侧设有激光器装置3，所述的激光器装置3包括支架3-1、激光笔3-2、分光镜3-3和一字镜片3-4，镜片固定架3-5通过转轴3-6按照直线阵列分布在所述支架3-1上，所述的分光镜3-3和一字镜片3-4安装在所述的镜片固定架3-5上，所述的激光笔3-2通过激光座3-7固定在所述的支架3-1上。
操作方式及原理为：操作者将任意物体放入圆柱形凹槽2内，然后打开本发明装置的激光笔3-2，激光笔3-2发出的光线通过分光镜3-3分离成激光束后，再通过一字镜片3-4折射透过缝隙2-1射入到圆柱形凹槽2内，此时激光束就会在物体表面显示出其等高线的所在。该发明装置利用统一平面上的光线能够在任一物体上显示等高线，简单明了，有助于人们对等高线的理解和学习。
以上所述，仅是对本发明的较佳实施例而已，并非是对本发明做其他形式的限制，任何熟悉本专业的技术人员可能利用上述揭示的技术内容加以变更或改型为等同变化的等效实施例。但是，凡是未脱离本发明方案内容，依据本发明的技术实质对以上实施例所做的任何简单修改、等同变化与改型，仍属于本发明的保护范围。
