Description

Technical Field

[0001] The utility model relates to the technical field of measuring rulers, in particular to a marking measuring ruler used on engineering sites. Background Art

[0002] A marking ruler used on construction sites, often referred to as an engineering ruler or construction site ruler, is a tool used to measure dimensions such as building width, height, and depth. This ruler, with its clearly marked graduations, helps users accurately measure various building dimensions and easily read the results. However, while traditional rulers can be extended or rotated to enhance their usability, they often lack a fixing mechanism. This can cause displacement during measurement, affecting data accuracy. Furthermore, due to frequent and long-term use on construction sites, rulers are susceptible to wear and tear, which reduces the accuracy of readings and potentially impacts the quality and safety of the project.

[0003] For example, Chinese patent CN220356228U discloses an engineering measuring ruler that includes a main ruler, a groove, a first movable axis, a secondary ruler, a scale, an automatically retractable rod, a marking assembly, and other components, capable of marking buildings. However, during use, the secondary ruler often struggles to securely fixate after rotation, which can lead to slight displacement or deformation during measurement, affecting the accuracy of the data and causing errors. Furthermore, after long-term use, the scale on the ruler may become blurred due to wear, which not only reduces the accuracy of the readings but also increases uncertainty during the measurement process, potentially impacting the quality and safety of the project.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0027] According to an embodiment of the utility model, a marking measuring ruler for use on a construction site is provided.

[0028] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Figure 1-Figure 5 As shown, a marking measuring ruler for an engineering site according to an embodiment of the present utility model includes a measuring plate 1, a groove 2 is provided at the top of the measuring plate 1, a telescopic measuring component 3 is arranged inside the groove 2, and the telescopic measuring component 3 is matched with the groove 2 through a rotating shaft 4, a fixing groove 5 is provided at the bottom of the groove 2, and an angle measuring component 6 connected to the telescopic measuring component 3 is arranged inside the fixing groove 5; a scale component 7 is provided on one side of the measuring plate 1, a protective component 8 is provided on the other side of the measuring plate 1, and a placement groove 9 is provided at one end of the measuring plate 1 to match the protective component 8.

[0032] In one embodiment, for the above-mentioned telescopic measuring component 3, the telescopic measuring component 3 includes a telescopic shell 301 arranged inside the groove 2 and cooperating with the rotating shaft 4, a limit groove 1 302 is symmetrically opened on the inner wall of the telescopic shell 301, a telescopic rod 303 cooperating with the limit groove 1 302 is arranged inside the telescopic shell 301, and a bolt 2 304 fixed to the telescopic rod 303 is arranged at the top of the telescopic shell 301; a scale 1 305 is provided on one side of the telescopic shell 301 and the telescopic rod 303, so that the length of the measuring ruler can be flexibly adjusted according to actual needs to adapt to measurement needs of different lengths.

[0034] The working principle of the angle measurement component 6 is as follows: by rotating the telescopic measuring component 3, the arc plate 606 moves under the rotation of the telescopic shell 301, thereby driving the limit column 2 607 to slide inside the through hole 2 605, prompting the arc shell 2 603 to move, so that the limit column 1 604 slides inside the through hole 1 602, thereby achieving accurate measurement of different angles, which helps the staff to grasp various angles more accurately and ensure the accuracy and quality of the project; when it is rotated to the specified angle, the telescopic shell 301 is fixed by rotating the bolt 10 to prevent slight deformation during the measurement process, thereby reducing measurement errors.

By providing bolts 10 and 2 304, the measuring ruler can be stably fixed at the required angle or length, not only effectively avoiding measurement errors caused by unexpected changes in angle or length during the measurement process, but also significantly enhancing the safety and reliability of the construction process; at the same time, the time for repeated adjustment and verification is reduced, thereby significantly improving work efficiency. By providing the scale assembly 7, the scale plate 702 can be easily replaced, thereby effectively avoiding wear or damage to the scale plate 702 after long-term use on the construction site.
