[0024] like Figures 1-7 As shown, a portable construction engineering surveying tool includes a first level body 1. A second level body 2 is symmetrically arranged on the left and right sides of the first level body 1. Two guide rods 3 are connected side-by-side on the side walls of the second level body 2 near the first level body 1. Guide holes 1-1 matching the guide rods 3 are provided on the left and right side walls of the first level body 1. A central level bubble 5 is installed in the middle of the top surface of the first level body 1. The levelness of the building is determined by judging the bubble in the central level bubble 5. A rotating handle 9 is installed on the top surface of the first level body 1, located to one side of the central level bubble 5. A side level bubble 6 is installed on the top surface of the second level body 2. A tension handle 7 is connected to the outer side wall of the second level body 2. Specifically, an angle scale is provided on the top surface of the second level body 2. Scale lines are engraved on the wall of the angle scale, and a side level bubble fixing seat is embedded inside the angle scale. The side level bubble 6 is installed inside the side level bubble fixing seat.
[0025] A magnetic block 8 is also installed on the side wall of the second level ruler body 2 near the first level ruler body 1. Metal insertion slots 1-2 matching the magnetic block 8 are opened on the left and right side walls of the first level ruler body 1. The magnetic block 8 is inserted into the metal insertion slot 1-2, and the magnetic block can be attracted to the inner wall of the metal frame to limit the position of the second level ruler body 2.
[0026] like Figure 3 As shown, a limiting groove 3-1 is provided on the top outer wall of the guide rod 3. A positioning bolt 4 is threadedly connected to the top surface of the first level body 1. The bottom of the positioning bolt 4 is pressed against the limiting groove 3-1. Hold the tension handle 7 and pull the second level body 2 outward to move the second level body 2 away from the first level body 1. The guide rod 3 slides along the guide hole 1-1. When the second level body 2 is pulled to the appropriate position, tighten the positioning bolt 4 so that the bottom end of the positioning bolt 4 is pressed against the limiting groove 3-1 to limit the second level body 2.
[0027] likeFigures 4-5 As shown, a limiting protrusion 3-3 is connected to one end of the limiting groove 3-1 away from the second level body 2, and a stop block 1-1-2 is connected to the outside of the guide hole 1-1 to prevent the limiting protrusion 3-3 from disengaging from the guide hole 1-1; by setting the limiting protrusion 3-3 and the stop block 1-1-2, the guide rod 3 is prevented from falling out of the guide hole 1-1.
[0028] like Figure 6 As shown, a guide bar 3-2 is connected to the bottom outer wall of the guide rod 3, and a guide groove 1-1-1 matching the guide bar 3-2 is opened on the inner wall of the guide hole 1-1; during the sliding process of the guide rod 3 along the guide hole 1-1, the guide bar 3-2 moves in the guide groove 1-1-1 to improve stability and prevent the position of the second level body 2 from shifting.
[0029] like Figure 7 As shown, the rotating handle 9 includes two mounting seats 9-1, which are mounted on the top surface of the first level body 1. A handle body 9-2 is movably disposed between the two mounting seats 9-1. A U-shaped mounting groove 9-1-1 is provided on the top of the mounting seat 9-1, and the end of the handle body 9-2 is rotatably connected to the mounting groove 9-1-1 through a rotating shaft.
[0030] The usage process of this utility model is as follows:
[0031] First, grasp the tension handle 7 and pull the second level ruler body 2 outward to move the second level ruler body 2 away from the first level ruler body 1. The guide rod 3 slides along the guide hole 1-1. After the second level ruler body 2 is pulled to the appropriate position, tighten the positioning bolt 4 so that the bottom end of the positioning bolt 4 is pressed against the limiting groove 3-1 to limit the second level ruler body 2. This installation method pulls both second level ruler bodies 2 to the appropriate position so that the overall length of the device meets the usage requirements.
[0032] Then, when using it, depending on the environment, hold the rotating handle 9 and place the device on the building to be calibrated. Determine whether the building is level by judging the bubble in the middle level bubble 5. If the bubble is in the middle position of the middle level bubble 5, it is level; otherwise, it is not level. If the building itself has a certain angle, such as 45 degrees, rotate the side level bubble fixing seat until the calibration line on the side level bubble 6 points to the 45-degree position of the scale line, and then perform calibration. At this time, place the device on the tilted building. If the bubble in the side level bubble 6 is in the middle position, it means that the tilt angle of this building is 45 degrees.
[0033] After use, the positioning bolt 4 is loosened, the second horizontal ruler body 2 is pushed to move towards the first horizontal ruler body 1, the magnetic block 8 is inserted with the metal insertion slot 1-2, the second horizontal ruler body 2 can be limited, the overall length of the device is shortened, and the device is convenient to carry.
[0034] The above-described embodiments are only used to describe the preferred modes of the present application, and do not limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements of the technical solutions of the present application made by those skilled in the art shall fall within the protection scope determined by the claims of the present application.
