Description

Technical Field

[0001] This utility model relates to the field of laser ranging technology, and more specifically, to a portable laser rangefinder. Background Technology

[0002] A laser rangefinder is an instrument that measures the distance to a target by modulating a laser beam with specific parameters. The measurement range of a laser rangefinder is typically 3.5 to 5000 meters. It works by emitting a laser beam towards the target, receiving the reflected laser beam, and using a timer to measure the time it takes for the laser beam to travel from emission to reception, thereby calculating the distance from the observer to the target.

[0003] Currently, traditional laser rangefinders on the market typically require a gimbal tripod for use. The tripod is fixed at the measurement location, and the laser rangefinder is placed on it for distance measurement. This is because: firstly, using a gimbal tripod improves distance measurement accuracy; secondly, traditional laser rangefinders are generally medium-sized devices, and their size makes them inconvenient for operators to hold while measuring, thus requiring the gimbal tripod for support. However, when the measurement location is complex and requires operators to carry the equipment on foot, traditional laser rangefinders, due to their complex structure and insufficient integration of functional modules, are large and inconvenient to carry. Furthermore, the need to carry a tripod during measurement undoubtedly increases the operator's workload and fails to meet the need for convenient measurement.

[0004] Therefore, how to provide a portable laser rangefinder with a compact structure, integrated functional modules, convenient portability and measurement, and simplified measurement difficulty has become a technical problem that urgently needs to be solved by those skilled in the art.
