[0002] In the process of building engineering detection, the floor height in the building needs to be measured, and a floor height detection device such as a laser range finder will be used during measurement. When the laser range finder is working, it emits a very thin laser beam towards the target. The laser beam reflected by the target is received by a photoelectric element, and the time from emission to reception of the laser beam is measured by a timer to calculate the distance from the observer to the target.
[0003] Prior art such as the utility model with publication number CN214252577U discloses a laser range finder for building engineering, which comprises a laser range finder main body and a plug rod. A display screen is embeddedly installed on the front side of the laser range finder main body. A control button is arranged on the front side of the laser range finder main body, below the display screen. A rectangular through hole is formed on the rear side of the laser range finder main body, and a cover plate is movably installed in the rectangular through hole by a hinge. A socket is fixedly installed on the rear side of the laser range finder main body, above the cover plate. A clamping hole is formed in the bottom of the socket. A hollow cylinder is fixedly installed on the rear side of the cover plate. An electromagnet is fixedly installed on the inner bottom of the hollow cylinder. The laser range finder for building engineering can automatically open the cover plate to facilitate maintenance of the internal components of the laser range finder main body when they fail, bringing a better use prospect. It solves the problems of the existing laser range finder for building engineering, such as certain drawbacks in use, precise structure assembly, difficulty in disassembly, and difficulty in maintenance when the internal components of the laser range finder fail.
[0004] In daily work, it is found that the existing laser range finder for building engineering detection lacks effective protection. Since it is always exposed, the laser head is continuously attacked by dust particles. The attachment of dust may interfere with the emission and reception of laser, and also cause erosion.
