[0007] To achieve the above object, the utility model provides the following technical solutions: a building construction leveling tool, including a chassis. The center of the upper surface of the chassis is fixedly connected with a support column, and the upper end of the support column is fixedly connected with a lower fixing plate. And a leveling instrument for leveling operation is arranged on the upper surface of the lower fixing plate. At the same time, a liquid state observer is fixedly connected to the front side of the upper surface of the chassis.

Specific implementation mode

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1: As Figures 1 - 5 shown in the technical solution, the present utility model provides the following technical solution: A leveling tool for building construction discloses a protection mechanism. By means of the protection mechanism, the phenomenon that the level gauge 19 is damaged during the handling of the device can be avoided: A support column 4 is fixedly connected to the center of the upper surface of the chassis 1, and the upper end of the support column 4 is fixedly connected to a lower fixing plate 5. And a level gauge 19 for leveling operation is arranged on the upper surface of the lower fixing plate 5. At the same time, a liquid level monitor 3 is fixedly connected to the front side of the upper surface of the chassis 1. A fixed protection plate 6 is fixedly connected to the upper surface of the lower fixing plate 5. And an upper fixing plate 7 is fixedly connected to the upper surface of the fixed protection plate 6. And a protection mechanism is arranged between the side of the upper fixing plate 7 and the side of the lower fixing plate 5. The protection mechanism realizes the all-round protection of the level gauge 19 through the position change of the adjusting protection plate 8 it includes. The protection mechanism includes limit blocks 11. Four groups of limit blocks 11 are respectively nested on the outer sides of the lower fixing plate 5 and the upper fixing plate 7. And an adjusting protection plate 8 is fixedly connected between the upper and lower groups of limit blocks 11. And an adjusting plate 9 is fixedly connected to the upper surface of the upper limit block 11 arranged on the upper side. At the same time, an adjusting shaft 10 is fixedly connected to the center of the adjusting plate 9. Two groups of fixed protection plates 6 and adjusting protection plates 8 are respectively arranged. And both the fixed protection plate 6 and the adjusting protection plate 8 are arranged in an arc structure. And the diameter of the adjusting protection plate 8 is greater than the maximum value of the diameter of the fixed protection plate 6. The upper limit block 11 forms a sliding structure with the upper fixing plate 7 through the adjusting plate 9. And the lower limit block 11 forms a sliding structure with the lower fixing plate 5 through the adjusting protection plate 8.

[0030] On the left and right sides of the lower surface of the chassis 1, adjusting screws 2 are provided. When it is necessary to level the building construction, the device can be moved to the required working location. At this time, observe the liquid state inside the liquid level indicator 3 provided on the upper surface of the chassis 1 to check whether the device is placed stably. At the same time, the user can manually rotate the adjusting screw 2, so that the adjusting screw 2 adjusts its position along the side of the chassis 1. Through the mutual cooperation between the adjusting screw 2 and the liquid level indicator 3, the overall horizontal state of the device can be further fine-tuned. When carrying the device, the adjusting shaft 10 can be rotated, so that the adjusting shaft 10 drives the adjusting plate 9 to rotate. At this time, the adjusting plate 9 can synchronously drive the limiting block 11 provided above to rotate, and drive the adjusting protection plate 8 to rotate in position through the limiting block 11, so that the adjusting protection plate 8 is misaligned with the fixed protection plate 6 to completely shield the level gauge 19. When the adjusting protection plate 8 rotates under the driving action of the upper limiting block 11, it will synchronously drive the lower limiting block 11 to slide along the side of the lower fixing plate 5. The upper fixing plate 7 limits the upper limiting block 11, and the lower fixing plate 5 limits the lower limiting block 11, so as to further improve the stability of the rotation of the adjusting protection plate 8, so that the adjusting protection plate 8 can change its position more stably, and further avoid the phenomenon that the level gauge 19 is damaged during the process of carrying the device.

[0031] Embodiment 2: As Figure 2 , Figure 4 , Figure 6 and Figure 7 shown in the technical solution, the present utility model provides the following technical solution: A leveling tool for building construction discloses a moving plate 13. The level gauge 19 can be further clamped by the moving plate 13 to ensure the stability of the level gauge 19: The adjusting shaft 10 is nested and connected below the upper fixing plate 7, and the lower end of the adjusting shaft 10 is fixedly connected with a turntable 12, and a rotating rod 18 is hinged to the side of the turntable 12. The other end of the rotating rod 18 is hinged with a moving plate 13. A limiting block 16 is fixedly connected to the upper surface of the moving plate 13, and a limiting groove 17 is opened on the lower surface of the upper fixing plate 7. The upper end of the limiting block 16 is nested and connected inside the limiting groove 17. The rotating rod 18 forms a rotating structure with the moving plate 13 through the turntable 12, and the limiting block 16 forms a sliding structure with the limiting groove 17 through the moving plate 13.

[0032] During the rotation of the adjustment shaft 10, the turntable 12 can be driven to rotate synchronously. At this time, the rotating turntable 12 can cause the rotating rods 18 on both sides to rotate, and the moving plate 13 is pulled to move through the rotating rods 18. While the moving plate 13 is moving, the limiting block 16 can be driven to slide limitedly inside the limiting groove 17 synchronously, thereby improving the stability of the movement of the moving plate 13. The moving plates 13 moving towards each other can clamp the leveling instrument 19, thereby further ensuring the stability of the leveling instrument 19 during use.

[0033] Embodiment 3: As Figure 6 and Figure 7 shown in the technical solution, the present utility model provides the following technical solution: A leveling tool for building construction discloses an airbag 14. The airbag 14 can reduce dust adhering to the surface of the leveling instrument 19. Two groups of moving plates 13 are symmetrically arranged on the left and right about the center point of the upper fixing plate 7, and an airbag 14 is fixedly connected between the two groups of upper fixing plates 7. A nozzle 15 is arranged through the front side of the airbag 14, and the output end of the nozzle 15 is located at the front end of the leveling instrument 19.

[0034] When the two groups of moving plates 13 are moving, the airbag 14 can be squeezed synchronously. At this time, the gas inside the airbag 14 can be ejected out through the nozzle 15, thereby cleaning the surface of the leveling instrument 19, and further avoiding the influence of the dust adhering to the surface of the leveling instrument 19 on the leveling operation.
