Description

Technical Field

[0002] In the process of building construction, in order to ensure the accuracy and efficiency of construction, a series of distance measurement and positioning devices are usually relied on. The main function of these devices is to help construction workers accurately measure specific distances and accurately locate the position of target points. These devices are generally composed of key structures such as rangefinders and three-dimensional locators, which play a vital role in building construction.

[0003] However, existing distance measurement and positioning devices for construction often face a common problem after completing their measurement tasks, that is, these measuring instruments are not easy to seal and protect after use. Due to the lack of effective protection measures, these instruments are often exposed to the external environment, which makes them extremely vulnerable to various damages, such as dust, moisture, impact and other external factors, thus affecting the service life and measurement accuracy of the instrument.
