Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, specifically to an indoor distance measuring device for civil engineering structural design. Background Technology

[0002] Modern interior design and decoration rely heavily on computer-aided design. Before interior design and decoration, reverse modeling of the building's interior is necessary, which requires detailed and accurate interior dimensions. Due to construction errors and other factors, the dimensions of the completed building's interior usually need to be remeasured to be known.

[0003] For example, patent number 201720522225.2 proposes an indoor four-way ranging device. Its description states: "It includes four parts: bracket 106, four-way laser ranging module, display screen 107, and internal power circuit..." Although this patent proposes an indoor four-way laser ranging module, the device has an irregular overall structure. In actual use, it is complex, bulky, and lacks flexibility, making it difficult to adapt to changes in different indoor environments and measurement needs. It cannot be freely switched for different indoor situations, thus limiting its effectiveness. Utility Model Content

[0047] For scenarios where measurement points need to be changed frequently, engineers can quickly adjust the measurement direction by simply plugging and unplugging component 4.

[0048] Engineers assess and analyze the structure of the interior space based on the measurement results and their professional knowledge.

[0052] A battery is fixedly connected to the inner wall of the grip 1 to provide power to the entire device.

[0053] A charging head 11 is fixedly connected to the bottom of the grip 1, which allows users to charge the battery and ensure the continuous use of the ranging device.

[0054] Fixed block 2:

[0055] The fixing block 2 is fixedly connected to the top of the handle 1, serving to support and connect other components.
