Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering equipment, in particular to a measuring ruler. Background Art

[0002] In the construction industry, accurate measuring tools are crucial for ensuring project quality and safety. With the continuous advancement of construction technology, the requirements for measuring tools' precision and functionality are becoming increasingly stringent. As a fundamental construction tool, the measuring level has evolved from simple to complex, and from single-function to multifunctional. Early levels relied primarily on physical principles, such as buoyancy or gravity, to achieve horizontal or vertical measurements. With the advancement of electronic technology, levels with integrated electronic sensors have emerged, providing more accurate measurements and simplifying operation. Furthermore, to adapt to diverse construction environments and requirements, the design of measuring levels continues to innovate, improving their applicability and portability.

[0003] Currently, construction measurement levels on the market fall into two main categories: traditional mechanical levels and modern electronic levels. Mechanical levels typically consist of a transparent glass or plastic tube with a built-in bubble. The position of the bubble is used to determine horizontal or vertical alignment. These levels are low-cost and easy to use, but they have limitations in terms of accuracy and durability. Electronic levels integrate electronic sensors and displays, providing digital readouts and higher accuracy, but are relatively expensive and require a power supply. Additionally, some high-end levels incorporate laser projection capabilities, allowing for the projection of horizontal or vertical reference lines from a distance. However, these devices are typically bulky and difficult to carry.

[0004] While existing construction level gauges have made significant technological progress, they still have some shortcomings. For example, most existing levels are single-function and cannot simultaneously measure verticality and length, limiting their multifunctional applications on construction sites.
