Description

Technical Field

[0001] This utility model belongs to the field of measuring equipment technology, and specifically relates to a laser rangefinder. Background Technology

[0002] Laser rangefinders are lightweight, compact, easy to operate, fast, and accurate, with an error only one-fifth to a few hundredths that of other optical rangefinders. They are widely used in architecture and engineering, geographic surveying and mapping, industrial manufacturing, aerospace and military, geological exploration, environmental monitoring, and other fields. In architectural surveying, laser rangefinders can be used to measure the height, width, and distance of buildings, helping architects and engineers accurately assess project scale and construction costs. Furthermore, they can be used for interior layout and furniture placement, optimizing space utilization. In engineering monitoring, laser rangefinders can accurately measure the dimensions and distances of components, ensuring construction accuracy and quality, and monitoring deformation and displacement of the project, promptly identifying and addressing potential safety hazards. The most common type of laser rangefinder is the handheld laser rangefinder, which calculates distance by emitting a laser and receiving the reflected beam. It typically has high accuracy within 200 meters. To measure, press the measurement reference selection key until the desired measurement reference edge is displayed. Then move the handheld laser rangefinder so that the laser point accurately reaches the point to be measured to measure the distance. It can be seen that the distance measurement point needs to be aligned in order to measure the distance accurately. Existing handheld laser rangefinders only emit a laser beam from the front end to measure the distance. When using the rangefinder, it is not easy to detect if the rangefinder is tilted or shaken, which will not only prolong the measurement time, but also affect the measurement accuracy.

The laser auxiliary mechanism 17 includes a cross beam emitter 18, a fixing frame 19, a lens 20 and a side button 21. The cross beam emitter 18 and the side button 21 are electrically connected to the battery compartment 3. The lower end of the fixing frame 19 is installed inside the lower housing 12, and the upper end is an arc-shaped groove for receiving the cross beam emitter 18. The cross beam emitter 18 is installed vertically to the lower housing 12. The lens 20 is vertically snapped onto the lower housing 12 and is located at the front end of the cross beam emitter 18.

[0018] In this embodiment, the front end of the housing 1 is the core 4, which includes a laser emitter and a receiver for distance measurement. The middle of the side is the laser auxiliary mechanism 17, which includes a cross beam emitter 18, a fixing frame 19, a lens 20, and a side button 21. The cross beam emitter 18 is activated by the side button 21, which emits a cross laser to correct the position and angle of the rangefinder by aligning it with the wall or reference surface, preventing tilting or shaking from affecting the accuracy of distance measurement. The cross laser can quickly locate the horizontality of the distance measurement point, thereby improving the efficiency of distance measurement.

[0019] The lower housing 12 is provided with a mounting groove 22 in the middle of its side for engaging the side button 21 and the lens 20, and a partition rib 23 is provided in the corresponding upper housing 11.

[0020] In this embodiment, the side button 21 and the lens 20 are respectively snapped into the lower housing 12 by the mounting groove 22. When the upper housing 11 and the lower housing 12 are fastened together, the side button 21 and the lens 20 are respectively fixed by the partition rib 23 to prevent shaking.
