[0021] Please see Figure 1 In this embodiment of the utility model, a vertical measuring ruler for building engineering includes a horizontal ruler 1. The horizontal ruler 1 includes a ruler body 2. A gripping hole 3 is provided inside the ruler body 2, and a level tube 4 is embedded and fixedly connected to both the upper and lower sides of the gripping hole 3 inside the ruler body 2.

[0022] The ruler 2 is placed against the wall of the building or other location, and its verticality is determined by the position of the bubble level in the level tube 4.

[0023] exist Figures 1 to 4 The system includes a first support block 5 and a support base 6 located above the first support block 5. The first support block 5 is fixed to the lower end of the left side surface of the ruler body 2, and the support base 6 is fixed to the upper end of the left side surface of the ruler body 2. A rack 7 is movably connected through the upper and lower surfaces of the support base 6. The rack 7 is slidably connected to the inner right side surface of the support base 6. A second support block 8 is fixed to the upper end of the rack 7. The second support block 8 is movably fitted against the left side surface of the ruler body 2. A rotating rod 9 is rotatably connected through the front surface of the support base 6. The rear end of the rotating rod 9 is fixed to... There is a gear 10, which is meshed with the rack 7. The outer surface of the rotating rod 9 is fixedly connected to the ratchet 11 in front of the support base 6. The front surface of the support base 6 is provided with a positioning mechanism 12 above the rotating rod 9. The positioning mechanism 12 includes a spring 13. The upper end of the spring 13 is fixedly connected to a positioning block 14, and the lower end of the spring 13 is fixedly connected to a pawl 15. The pawl 15 is attached to the ratchet 11. The right end of the pawl 15 is rotatably connected to a positioning rod 16. The rear ends of the positioning block 14 and the positioning rod 16 are both fixedly connected to the front surface of the support base 6.

[0024] The left surfaces of the first support block 5 and the second support block 8 are flush, that is, they are located on the same plane;

[0025] Pulling the second support block 8 upwards causes the rack 7 to rise, which increases the distance between the first support block 5 and the second support block 8, effectively lengthening the entire measuring ruler so that it can measure higher positions.

[0026] Pawl 15 engages with ratchet 11, preventing ratchet 11 from rotating clockwise. Consequently, gear 10 cannot rotate clockwise, and the second support block 8 will not cause rack 7 to descend due to its own weight. After pulling pawl 15 away from ratchet 11, the second support block 8 will cause rack 7 to descend.

[0027] The working principle of this utility model is as follows: When in use, when the detection point is high, the user can directly pull the second support block 8 upward to drive the rack 7 to rise, thus lengthening the entire detection ruler; then, the ruler body 2 is placed against the detection point through the first support block 5 and the second support block 8, with the first support block 5 against the lower position of the detection point and the second support block 8 against the higher position of the detection point. The verticality of the wall is judged by the state of the level tube 4. After the detection is completed, the pawl 15 is pulled upward to move it away from the ratchet 11, and the second support block 8 will drive the rack 7 to descend to complete the reset.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
