Description

Technical Field

[0001] The utility model relates to the technical field of laser rangefinders, and more specifically, to a laser rangefinder for indoor measurement. Background Art

[0002] Indoor measurement is a very important link in industries such as construction, decoration, real estate, and property management. Traditional indoor measurement methods mostly use tools such as tape measures, distance measuring wheels, or optical levels. Although these methods can complete basic measurement tasks, they have problems such as cumbersome operation, low efficiency, and limited accuracy. With the development of technology, laser ranging technology has been widely used in the field of indoor measurement due to its non-contact, high-precision, and fast response characteristics.

[0003] For example, a Chinese patent with the publication number CN209541723U discloses a laser rangefinder, which includes a housing having a receiving space, a ranging device received inside the housing. The ranging device includes a laser emitting device and a laser receiving device exposed from the front end of the housing. A rod extends backward from the rear end of the housing, and a weight is provided on the rod and fixed to the rod by a flexible cord. A right-angle ruler is provided below the rod at the rear end of the housing. The right-angle ruler includes a horizontal portion and a vertical portion. The horizontal portion is disposed opposite to the rod, the vertical portion faces the bottom end of the housing and is perpendicular to the bottom surface of the housing, and the vertical portion is located between the housing and the cord and is disposed opposite to the cord;

[0004] The technical solution described in this scheme can reflect whether the front end and the rear end of the laser rangefinder are in a horizontal state by comparing the intervals between the top and the bottom of the cord and the vertical portion, and thus can reflect whether the laser rangefinder is in a horizontal state during use. However, when this scheme is in use, it does not have a protection function for the laser emitting device and the laser receiving device, resulting in easy wear of these parts during carrying, and inconvenient holding during measurement, affecting the user experience.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a laser rangefinder for indoor measurement is provided, in order to achieve a more practical and valuable purpose. Summary of the Utility Model
