[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1:

[0029] like Figure 1-3 As shown, it provides an example of the basic structure of the level measuring device used for engineering supervision in this example.

[0030] Based on the diagram, the level measuring device used for project supervision specifically includes a support 1, a groove 2 is provided at the front end of the support 1, a slide groove 3 is provided at the front end of the support 1, an insert block 4 is provided inside the slide groove 3, the front end of the support 1 is rotatably connected to the measuring cross bar 5, the upper end of the support 1 is fixedly connected to the handle 6, the lower end of the support 1 is fixedly connected to the adjustable support foot 7, the rear end of the support 1 is fixedly connected to the pulley 8, the rear end of the support 1 is provided with a first placement groove 9 and a second placement groove 10, the inside of the first placement groove 9 and the second placement groove 10 are both fixedly connected to a baffle 11, the inside of the first placement groove 9 is provided with a measuring vertical rod 12, and the inside of the second placement groove 10 is provided with a support rod 13.

[0031] The following is a detailed description of the structure and technical features of the level measuring device for engineering supervision given in this example.

[0032] Combine Figure 1 and Figure 5As shown, in some embodiments of this example, the measuring crossbar 5 in the level measuring device for engineering supervision specifically includes the following components: a crossbar body 501, a long slot 502, a sliding bar 503, a slider 504, a paddle 505, a first scale line 506, a limiting slot 507, and a spirit level 508. The front end of the crossbar body 501 is provided with a long slot 502, the interior of the long slot 502 is fixedly connected to the sliding bar 503, the interior of the long slot 502 is provided with a slider 504, the front end of the slider 504 is fixedly connected to the paddle 505, the front end of the crossbar body 501 is provided with a first scale line 506, limiting slots 507 are provided on both sides of the crossbar body 501, and the left side of the crossbar body 501 is fixedly connected to the spirit level 508.

[0033] The measuring horizontal rod 5 of such a structure can cooperate with the measuring vertical rod 12 to perform levelness measurement.

[0034] Furthermore, the slider 504 in the measuring crossbar 5 is slidably connected to the long slot 502, which is in turn slidably connected to the slide bar 503. Through the organic coordination between the slider 504 and the long slot 502, the measuring vertical rod 12 is inserted into the slider 504. By turning the paddle 505, the slider 504 moves within the long slot 502 along the slide bar 503, and the measuring vertical rod 12 moves accordingly. The roller 1203 rolls in contact with the contact surface, and when the horizontal height increases, the vertical rod body 1201 moves upward. The horizontal height difference within a unit length can be measured through the changes in the readings of the first scale line 506 and the second scale line 1202.

[0035] Furthermore, the retaining groove 507 in the measuring crossbar 5 is adapted to fit the insert block 4, which is slidably connected to the chute 3. Due to the seamless coordination between the retaining groove 507 and the insert block 4, the measuring crossbar 5 can be rotated and placed into the groove 2 when not in use, with the retaining plate 11 securing the measuring crossbar 5. To perform level measurements, the measuring crossbar 5 is rotated and the insert block 4 is moved toward the center until the insert block 4 fits into the retaining groove 507, locking the measuring crossbar 5.

[0036] Example 2:

[0037] Based on the solution in Example 1, this example further provides an optimized solution.

[0038] Combine Figure 3 and 4 To be honest, in this example, a specific structural solution is provided for the measuring vertical rod 12 in the level measuring device for engineering supervision.

[0039] Specifically, the measuring rod 12 includes a rod body 1201, a second scale line 1202, and a roller 1203. The second scale line 1202 is formed at the rear end of the rod body 1201, and the lower end of the rod body 1201 is fixedly connected to the roller 1203. With this structure, the measuring rod 12 is configured to cooperate with the support rod 13, allowing the measuring rod 12 and the support rod 13 to be placed in the first placement slot 9 and the second placement slot 10, respectively, for easy storage.

[0040] Furthermore, in this embodiment, the vertical rod body 1201 is slidably connected to the slider 504, and the upper end of the support rod 13 is threaded, and the support rod 13 is threadedly connected to the crossbar body 501. In this way, during testing, the support rod 13 is threadedly connected to the crossbar body 501 to provide support for the crossbar body 501. The level 508 is observed to adjust the height of the adjustable foot 7 or the screwing height of the support rod 13 and the crossbar body 501 until the level 508 is balanced, thereby adjusting the level of the crossbar body 501.

[0041] For further explanation, in this example, the baffle 11 in the engineering supervision level gauge is made of natural rubber, and two identical pulleys 8 are provided. This natural rubber baffle 11 retracts the horizontal measuring rod 5, vertical measuring rod 12, and support rod 13 into the support 1. The baffle 11 blocks and limits the level gauge, and by pulling the handle 6, the pulley 8 can be used to drag and transport the level gauge, enhancing portability.

[0042] Regarding the level measuring device for engineering supervision formed by the above example solution, the application process is described in detail below.

[0043] Combine Figures 1 to 5 As shown, when using this engineering supervision level measuring device, the measuring crossbar 5 is rotated, the insert block 4 is moved toward the center until the insert block 4 is inserted into the limit slot 507, the measuring crossbar 5 is locked, the support rod 13 is threadedly connected to the crossbar body 501 to provide support for the crossbar body 501, and the level 508 is observed to adjust the height of the adjustable support foot 7 or the screwing height of the support rod 13 and the crossbar body 501 until the level 508 is balanced, thereby adjusting the level of the crossbar body 501.

[0044] Insert the measuring vertical rod 12 into the slider 504, and by toggling the paddle 505, the slider 504 moves along the slide bar 503 in the long slot 502, and the measuring vertical rod 12 moves accordingly, and the roller 1203 rolls in contact with the contact surface;

[0045] When the level height increases, the vertical rod body 1201 moves upward. The level height difference within a unit length can be measured through the changes in the readings of the first scale line 506 and the second scale line 1202. The handle 6 is pulled and the level meter is dragged and transported with the help of the pulley 8 to improve portability.
