[0001] The utility model relates to the technical field of measuring instruments, in particular to a portable gravity type construction measuring instrument. Background Technique

[0002] During the construction process, the control of the levelness and perpendicularity is a key process in quality control. How to control the levelness and perpendicularity of building construction has long become a key factor affecting the construction quality. Due to the large volume of various levelness and perpendicularity measuring devices, they are not suitable for carrying during daily construction management work and can only be carried by a special person during special quality inspections. Coupled with the fact that the naked eye cannot accurately distinguish the levelness and perpendicularity to meet the construction quality requirements, it is difficult to manage and control the levelness and perpendicularity in construction management work, which in turn affects the overall quality perception of building construction and causes a series of subsequent problems. Therefore, the utility model proposes a portable gravity type construction measuring instrument to solve the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to provide a portable gravity type construction measuring instrument to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A portable gravity type construction measuring instrument, comprising: a handle, a grooved frame and a transparent scale disk. The handle is fixedly installed on the outer wall of one end of the grooved frame, and the transparent scale disk is rotatably connected within the grooved frame. A groove is formed on the side wall of one end of the handle, and a round bead is rotatably connected to the center of the transparent scale disk through a mounting block.

[0005] The upper and lower ends of the round bead are located outside the mounting block and the transparent scale disk, and a plumb bob component is installed at the lower end of the round bead through a pendulum rope.

[0006] Preferably, a rubber sleeve is fixedly installed in the groove.

[0024] For the purposes of simplicity and illustration, the principles of the embodiments are mainly described by reference to examples. In the following description, many specific details are set forth in order to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures are not described in detail to avoid unnecessarily obscuring these embodiments. Additionally, all embodiments can be used in combination with each other.

[0025] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: a portable gravity construction surveying instrument, including: a handle 1, a grooved frame 4, and a transparent scale disk 5. The handle 1 is fixedly installed on the outer wall of one end of the grooved frame 4. A groove 2 is formed on the side wall of one end of the handle 1, and a rubber sleeve 3 is fixedly installed in the groove 2. When not in use, the plumb bob 15 can be inserted into the groove 2 by squeezing the rubber sleeve 3, which is convenient for fixing and storing the plumb bob 15.

[0026] The transparent scale disk 5 is rotatably connected in the grooved frame 4. Symmetrically fixed on the side walls at the front and rear ends of the transparent scale disk 5 are rotating shafts 6. The other ends of the rotating shafts 6 are rotatably connected to fixing blocks 7. The fixing blocks 7 are fixedly installed at the inner ends of the grooved frame 4. The transparent scale disk 5 can thus rotate in the grooved frame 4 through the rotating shafts 6. A scale table is provided on the outer side wall of the transparent scale disk 5, which is convenient for observation during use.

[0027] At the center of the transparent dial 5, a ball 11 is rotatably connected through a mounting block 9. The upper and lower ends of the ball 11 are located outside the mounting block 9 and the transparent dial 5. At the center of the upper end of the transparent dial 5, a mounting groove 8 is provided. A mounting block 9 is fixedly installed in the mounting groove 8. A spherical rotating groove 10 is provided in the mounting block 9 and the mounting groove 8. The spherical rotating groove 10 penetrates the side walls of the transparent dial 5 and the mounting block 9. The ball 11 is rotatably installed in the rotating groove 10. By first placing the ball 11 in the mounting groove 8 and then bonding the mounting block 9 in the mounting groove 8, the ball 11 is rotatably installed in the transparent dial 5. One end of the pendulum rope 12 is fixedly installed on the side wall of one end of the ball 11. A plumb weight component 101 is installed at the lower end of the ball 11 through the pendulum rope. When the transparent dial 5 is rotated, the pendulum rope 12 drives the plumb weight component 101 to rotate on one side of the transparent dial 5 under the action of the ball 11.

[0028] The plumb weight component 101 includes a cover plate 13 and a plumb bob 15. A round hole is provided on the side wall of the cover plate 13. A threaded cylinder 14 is installed outside one end of the cover plate 13. The other end of the pendulum rope 12 passes through the round hole on the cover plate 13 and is fixedly installed with a baffle 17. The baffle 17 is located inside the threaded cylinder 14, thereby fixedly connecting the other end of the pendulum rope 12 and the cover plate 13.

[0029] A threaded groove 16 is provided at the upper end of the plumb bob 15. The outer wall of the threaded cylinder 14 is threadedly connected to the inner wall of the threaded groove 16, thereby fixing the plumb bob 15 at the lower end of the cover plate 13, which facilitates the disassembly and assembly of the plumb bob 15 and the replacement of the pendulum rope 12.

[0030] During the use of this device, due to the gravity factor, the plumb bob 15 is always perpendicular to the horizontal plane, and drives the transparent dial 5 to be horizontal or vertical through the pendulum rope 12 and the ball 11. At this time, through the transparent dial 5, the angle between the structure to be measured and the horizontal line or the vertical line can be read, so as to determine the levelness and perpendicularity of the structure to be measured.

[0031] This tool has two usage methods:

[0032] (1) Use the plumb bob 15 to adjust the transparent dial 5 to the vertical state, and read the inclination of the wall through the transparent dial 5;

[0033] (2) Use the plumb bob 15 to adjust the transparent dial 5 to the vertical state, and read the levelness of the wall through the transparent dial 5.

[0034] In addition to the rough measurement of levelness and perpendicularity, this device can also use the plumb bob 15, the pendulum line 12 and the transparent dial 5 as a simple protractor to check the dimensions of the construction site materials.

[0035] The radius of the transparent scale dial 5 is 10 cm. The scale can be in degrees or the scale on one side can be marked in a style that allows for direct reading of data according to a conversion table. As shown in the table below. In this way, the invention can be used to read both lengths and angles. The sine table can be engraved on the handle 1 for convenient on-site reading of data.

The scope of the present utility model is defined by the appended claims and their equivalents.
