A protective cover device for a laser range finder comprises a concave laser protective cover (1) and a concave reflector protective cover (3). The concave laser protection cover is installed on the laser range finder (2), and the reflector (4) is installed in the concave reflector protection cover. And laser (5) emitted by the laser range finder passes through the concave laser protection cover and is vertically emitted to the reflecting plate in the concave reflecting plate protection cover. According to the device provided by the utility model, through the design of the concave protective cover, the interference of external strong light on laser ranging measurement is solved, and the laser range finder provided with the protective cover device can accurately judge the deformation measurement of a geological disaster monitoring point. 一种用于激光测距仪的保护罩装置，包括凹型激光保护罩（1）和凹型反光板保护罩（3）；所述凹型激光保护罩安装在激光测距仪（2）上，所述反光板（4）安装在凹型反光板保护罩内。所述激光测距仪发出的激光（5）穿过凹型激光保护罩垂直射向凹型反光板保护罩内的反光板上。本实用新型装置，通过内凹型保护罩设计，解决外部强光对激光测距测量的干扰，装有保护罩装置的激光测距
