Description

Technical Field

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

[0002] Construction projects refer to the construction and building activities of various buildings and facilities carried out on land, including house construction, road construction, bridge construction, water conservancy projects, urban planning and landscaping, etc. Construction projects need to go through multiple stages such as planning, design, construction and acceptance, involving land use, resource allocation, environmental protection and other aspects.

[0003] During the construction process, construction workers need to measure the length of building materials and other objects from time to time. The existing measuring tools have at least the following disadvantages: the existing measuring tools have relatively single functions and are not convenient to use. Moreover, when the existing measuring tools are used in a dark environment, it is not convenient to observe the measurement results. Therefore, we have introduced a new multifunctional measuring tool for construction projects.

[0004] A Chinese patent for a multifunctional measuring tool for construction projects (publication number CN219121227U) is proposed in the prior art to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: by integrating a tape measure, an angle ruler and a horizontal tube into one, the device can perform length measurement, horizontal measurement and angle measurement of objects. Combining multiple measuring tools together can make users do not need to carry more measuring tools when measuring, and it is more convenient to use. However, in this technology, during the measurement of the angle of the object, the angle ruler is fixedly connected to the shell. When the angle ruler measures the angle, the center point of the angle ruler needs to be aligned with the angle to be measured. However, the angle ruler in the device cannot be aligned with the angle to be measured due to the influence of the shell, and cannot fit the angle to be measured at all when measuring the angle in some narrow areas, so it is difficult to accurately measure the angle, which needs to be improved urgently. Summary of the invention

[0005] The purpose of the utility model is to provide a multifunctional measuring tool for construction to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

The independently arranged angle ruler can measure the angle more flexibly. At the same time, the angle ruler is fixed by the lock, which is extremely convenient to take and fix, thereby greatly improving the measurement efficiency and accuracy of the construction project.

[0013] A further improvement of the technical solution of the utility model is that: the outer side of the extension rod is threadedly connected with a second adjusting screw for fixing the graphite core, and one end of the second adjusting screw extends to the inside of the placement hole and contacts the outer side of the graphite core.
