Abstract
Description
Technical Field
[0001] The utility model relates to the field of level measurement, in particular to a level measuring ruler with adjustable length. Background Art
[0002] A level ruler is a tool for measuring horizontal lines. Existing level rulers are generally of fixed length, and are often difficult to use when measuring long sections. Existing level rulers do not have a stable grip structure, which easily leads to inaccurate data read during use. Existing level rulers can only measure horizontal structures, and other equipment needs to be used again when measuring length, which limits their versatility. An existing level ruler assembly and a detachable level ruler (publication number: CN218822360U) have at least the following disadvantages in use:
[0003] 1. Existing leveling rulers are generally of fixed length. When encountering gullies that are too long, they often face difficulties in use or even cannot be used normally. This is because fixed-length measuring rulers cannot flexibly adjust the length, resulting in many limitations in accurate measurement in complex projects, so a retractable leveling ruler is urgently needed.
[0004] 2. The existing level ruler lacks a stable holding structure, which makes it impossible to firmly fix it on the plane to be measured when measuring the level. Due to the lack of a stable holding structure, it is often difficult for users to keep the ruler stable when measuring, which affects the accuracy of the measurement results. Therefore, a stable holding level ruler is urgently needed.
[0005] 3. The existing leveling ruler can only measure the horizontality of objects or the ground, and cannot provide other data or measure additional parameters, which leads to its lack of sufficient versatility and multifunctionality. In practical applications, in addition to horizontality, it is sometimes necessary to measure other data such as verticality and inclination angle to comprehensively evaluate the state of objects or the ground. Due to the limitations of existing leveling rulers, users cannot perform more comprehensive and accurate measurements, which makes it appear to be very limited in certain application scenarios. Therefore, a multifunctional leveling ruler is urgently needed. Utility Model Content
