[0002] For the newly poured small-area concrete floor in a construction site, in order to prevent unevenness and subsequent water accumulation, it is necessary to measure the level. When measuring, a level surveying instrument is used for ground detection.

[0003] According to the patent with the application number 202321080349.1, a ground level surveying instrument is disclosed, which includes a U-shaped tube and two movable rods. Both movable rods movably penetrate the U-shaped tube. A plurality of jacks are opened on one side of both movable rods. One end of the bottom of both movable rods is welded with a leg. The middle of the top of the U-shaped tube is adhesively connected with a fixed block, and the middle of the top of the fixed block is fixedly embedded with a calibration tube; One end of the front side and one end of the back side of the U-shaped tube are adhesively connected with a C-shaped block, and one end of an insertion post movably penetrates through one side of both C-shaped blocks.

[0004] By pulling or pushing the two movable rods, the distance between the two movable rods is adjusted, and then one end of each of the two insertion posts is movably inserted into one of the jacks opened on one side of the two movable rods to fix the two movable rods, so that the ground with different widths can be leveled. However, there are still some deficiencies in the actual use of the above solution; although the insertion posts in the above solution can limit the position of the movable rods, if the pulled position of the movable rod is just in the middle of the insertion post, the limit of the movable rod cannot be achieved, which will affect the subsequent surveying and mapping work and thus reduce the practicability of the device. Therefore, we provide a ground level surveying instrument to solve the above problems. Content of the Utility Model

[0007] Furthermore, the surveying and mapping assembly includes two movable plates, the bottom surfaces of the two movable plates are slidably connected to the inner bottom wall of the connecting shell, and the side surfaces of the two movable plates close to each other are fixedly connected to a gear plate.

DETAILED DESCRIPTION

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] This embodiment provides a ground level surveying instrument, which is used to measure the level of the ground after concrete is poured on the ground. The limit assembly 8 can be used to limit the rotating rod 6, so that the device can arbitrarily fix different extended lengths without the situation where the movable plate 701 cannot be limited, thereby improving the practicality of the device.

[0022] See also Figure 1 to Figure 4 , including a connecting shell 1, the upper surface of which is fixedly connected with two handles 2 of the same size. The handles 2 are provided to facilitate the staff to carry the device, which is beneficial to the subsequent horizontal mapping work of the ground.

[0023] A U-shaped plate 3 is fixedly connected to the upper surface of the connecting shell 1 , a mounting plate 4 is fixedly connected to the upper surface of the connecting shell 1 , and a level 5 is mounted on the upper surface of the mounting plate 4 .

[0024] The provided mounting plate 4 enables the installation of the level 5, making the level 5 more stable during use and ensuring the accuracy during surveying and mapping. The U-shaped plate 3 can block the sunlight, making it convenient for subsequent observation of the level 5 and ensuring the accuracy during surveying and mapping.

[0025] The upper surface of the connecting shell 1 is rotatably connected to a rotating rod 6, and the upper surface of the rotating rod 6 is fixedly connected to a circular plate. The provided circular plate can facilitate the rotation of the rotating rod 6 and facilitate the subsequent adjustment of the overall length of the device.

[0026] A surveying and mapping assembly 7 is installed at the bottom end of the rotating rod 6, and the surveying and mapping assembly 7 includes two movable plates 701. The bottom surfaces of the two movable plates 701 are slidably connected to the inner bottom wall of the connecting shell 1, and the side surfaces of the two movable plates 701 close to each other are fixedly connected to a gear plate 702. The surveying and mapping assembly 7 also includes a gear body 703. The upper surface of the gear body 703 is fixedly connected to the bottom end of the rotating rod 6, and the gear body 703 is meshed with the two gear plates 702.

[0027] By rotating the rotating rod 6, during the rotation process, the rotating rod 6 utilizes the meshing between the gear body 703 and the gear plate 702 to enable the two movable plates 701 to move away from each other, thereby facilitating subsequent ground surveying and mapping work.

[0028] The surveying and mapping component 7 also includes two limit rods 705 of the same model, the top ends of the two limit rods 705 are fixedly connected to the inner bottom wall of the connecting shell 1, the upper surfaces of the two movable plates 701 are provided with limit grooves 704, and the outer surfaces of the two limit rods 705 are respectively slidably connected to the inner walls of the limit grooves 704.

[0029] When the movable plate 701 moves, the sliding connection between the limit groove 704 and the limit rod 705 can be used to guide the movable plate 701, ensure the stability of the movable plate 701 during movement, and ensure the accuracy of subsequent ground surveying.

[0030] The left and right sides of the two movable plates 701 are fixedly connected with support legs 706, and the bottom ends of the support legs 706 are fixedly connected with support seats 707, which realizes the support of the movable plates 701 and also realizes the support of this device, facilitating the subsequent horizontal mapping of the ground.

[0031] A limit assembly 8 is installed on the outer surface of the rotating rod 6, and the limit assembly 8 includes a first connecting ring 801 and a connecting rod 802. The first connecting ring 801 is fixedly connected to the outer surface of the rotating rod 6, the bottom end of the connecting rod 802 is fixedly connected to the upper surface of the connecting shell 1, and the top end of the connecting rod 802 is fixedly connected to the second connecting ring 803. The first connecting ring 801 and the connecting rod 802 are both made of 304 stainless steel. The stainless steel material can extend the service life of this device.

[0032] The outer surface of the second connecting ring 803 and the outer surface of the first connecting ring 801 are both provided with a connecting sleeve 804, and the material of the connecting sleeve 804 is rubber. The rubber material has a certain elasticity, so that the connecting sleeve 804 can fit more closely with the stainless steel tie 805 after being squeezed, and can avoid slipping. A stainless steel tie 805 is installed between the first connecting ring 801 and the second connecting ring 803. By rotating the bolts on the stainless steel tie 805, the tightness of the stainless steel tie 805 can be adjusted, and the rotation of the rotating rod 6 can be arbitrarily positioned, which is convenient for the subsequent measurement of bottom surfaces of different lengths by this device.

[0033] Working principle: When using this device, first move the device to the construction area through the handle 2, then rotate the rotating rod 6, and the gear body 703 will also rotate during the rotation of the rotating rod 6. By utilizing the meshing between the gear body 703 and the gear plate 702, the gear body 703 rotates, and the two moving plates 701 will move to the side away from each other, thereby increasing the overall length of the device and facilitating subsequent adjustments. When adjusted to an appropriate length, the stainless steel cable tie 805 is placed between the second connecting ring 803 and the first connecting ring 801. Then, the tightness of the stainless steel tie 805 is adjusted by rotating the bolt on the stainless steel tie 805. When the tightness of the stainless steel tie 805 is adjusted to be level with the first connecting ring 801 and the second connecting ring 803, the bolt is rotated half a circle to make the contact between the stainless steel tie 805 and the second connecting ring 803 and the first connecting ring 801 more closely fit, so as to limit the rotation of the rotating rod 6, so that the device can arbitrarily fix different extended lengths, and there will be no situation where the movable plate 701 cannot be limited, thereby improving the practicality of the device.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
