[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The embodiment of the present application discloses a measuring ruler for engineering assessment. Figure 1-Figure 2, including a measuring rod 1, the bottom end of the outer wall of the measuring rod 1 is fixedly connected to a handle 13, which is convenient for hand-held use and improves convenience. A movable slide 2 is provided inside the measuring rod 1, and a movable rotating shaft 5 is provided inside the movable slide 2. A measuring scale plate 3 is installed on the rotating shaft 5, and a slide groove 7 is provided inside the measuring scale plate 3. One end of the rotating shaft 5 extends to the outside of the slide groove 7 and is connected with a fixing nut 6. Therefore, when the fixing nut 6 is loosened, the rotating shaft 5 can move horizontally or vertically in the movable slide 2 and the slide groove 7, and the practical position and height of the measuring scale plate 3 can be adjusted accordingly, which is suitable for various surveying and mapping needs of engineering design, and scale bars 4 are provided on the surfaces of the measuring rod 1 and the measuring scale plate 3. The design of the scale bar 4 facilitates observation of the measured distance.

[0020] In the present application, a marking pen 12 is provided at one end of the measuring scale plate 3, and a rotating shaft 10 is installed on the top of one end of the measuring scale plate 3. A mounting part 11 is rotatably connected to the rotating shaft 10. The marking pen 12 is connected to the mounting part 11 by screws. Therefore, the mounting part 11 rotates on the rotating shaft 10 to drive the marking pen 12 to adjust to the corresponding position, thereby facilitating marking.

[0021] Combine Figure 3 As shown, a movable frame 9 is slidingly provided at the bottom of the measuring scale plate 3, and a marking pen 14 is connected to the outer wall of the movable frame 9. A positioning mechanism is provided inside the movable frame 9, and the positioning mechanism includes a card block 18. A plurality of tooth grooves 8 adapted to the card block 18 are equidistantly provided on the back wall of the measuring scale plate 3. A mounting cavity is provided inside the movable frame 9, and a roller is rotatably installed at the bottom end of the inner wall of the mounting cavity. A sliding groove adapted to the roller is provided at the center of the bottom of the measuring scale plate 3. The roller is located in the sliding groove to facilitate the sliding adjustment of the position of the movable frame 9 on the measuring scale plate 3. The adjustability of the movable frame 9 makes the positioning of the surveying and mapping points more accurate, and can be fine-tuned according to actual conditions to ensure the reliability of the surveying and mapping results.

[0022] In the present application, a movable cavity 15 is opened on one side of the inner wall of the movable frame 9, and a pull rod 16 is movably connected to the center of the inner wall of the movable cavity 15. One end of the pull rod 16 extends into the installation cavity and is movably connected to the block 18, and a spring 17 is provided between the block 18 and the pull rod 16. Therefore, by pulling the pull rod 16 outward, the block 18 can be driven out of the tooth groove 8, and the limit can be released, thereby facilitating and flexibly adjusting the marking position of the marking pen 2 14.

[0023] The implementation principle of a measuring ruler for engineering assessment in the embodiment of the present application is as follows:

[0024] During use, according to the surveying and mapping requirements, loosen the fixing nut 6, then operate the rotating shaft 5 to slide in the moving slide 2 and the slide groove 7 to adjust the height and angle of the measuring scale plate 3 on the measuring rod 1. During this process, the reading can be made through the scale bar 4. After adjusting to the appropriate position, tighten the fixing nut 6 to fix it. Then, the mounting part 11 outside the rotating shaft 10 can be rotated to adjust the marking angle of the marking pen 12, thereby improving the flexibility of use. By pulling the pull rod 16 to squeeze the spring 17, the block 18 is driven out of the tooth groove 8. At this time, the movable frame 9 can be pushed to move with the roller at the bottom of the measuring scale plate 3 to adjust the corresponding surveying and mapping position, which is convenient for the operator to quickly lock and unlock the movable frame 9, and then hold the handle 13 to make the marking pen 2 14 close to the surveying and mapping point for marking. The overall structure is simple and ingenious, which can meet different surveying and mapping requirements and improve the precision and accuracy of surveying and mapping.
