Description

Technical Field

[0001] The utility model belongs to the technical field of measuring rulers, and in particular relates to a measuring ruler. Background Art

[0002] When carrying out construction of a building project, it is necessary to draw and measure the construction drawings on the surface of the drawing board. In the process of drawing and measuring the drawings, it is often necessary to measure some information such as length, angle, verticality, etc. with a measuring ruler.

[0003] A Chinese patent with authorization announcement number CN 208313298 U discloses a measuring ruler for construction engineering management, including a measuring ruler, a level ruler, a calibration component and a storage slot. The measuring ruler consists of a horizontal ruler and a vertical ruler. The vertical ruler is arranged on one side of the horizontal ruler. The front surfaces of the horizontal ruler and the vertical ruler are both provided with scale lines. The patent can perform length measurement and verticality detection by arranging the horizontal ruler and the vertical ruler. However, since the relative angle between the horizontal ruler and the vertical ruler is fixed, angle measurement cannot be performed. At the same time, the measuring ruler is not convenient for adjusting the length of the measuring ruler during use. The existing engineering drawings are generally large in size and require a longer ruler for measurement, but the longer ruler is not convenient for the staff to carry. Utility Model Content

A sliding groove 4 for storing the movable ruler 2 is downwardly opened on the top of the fixed ruler 1, and the end of the sliding groove 4 away from the angle ruler 3 penetrates to the outside of the fixed ruler 1. A movable groove 5 connected to the sliding groove 4 is opened on the outer surface of the fixed ruler 1. A lever 6 connected to the movable ruler 2 is slidably connected inside the movable groove 5. A limiting component for positioning the movable ruler 2 is arranged at the bottom of the lever 6. By arranging the fixed ruler 1, the movable ruler 2 and the angle ruler 3, it is not only convenient to The length of the measuring ruler can be adjusted, which is convenient for the staff to carry and use, and can also be convenient for measuring the angles of the drawings, without carrying multiple measuring tools, thereby improving the practicality of the measuring ruler. The limit assembly includes a limit plate 7 arranged at the bottom of the lever 6, a limit rod 8 slidably connected to the middle of the limit plate 7, a jack 9 opened on the side of the movable ruler 2 close to the lever 6, a spring 10 arranged on the outside of the limit rod 8 and used to connect the limit rod 8 and the limit plate 7, and positioning holes 11 symmetrically opened on both sides of the fixed ruler 1 and adapted to the limit rod 8. When the movable ruler 2 is moved out of the fixed ruler 1 along the slide groove 4, the limit rod 8 is pulled outward to release the limit of the movable ruler 2 by the limit rod 8, and the spring 10 is stretched, and the movable ruler 2 is moved to the tail end of the slide groove 4. After that, the limit rod 8 is reset and inserted into the socket 9 along the positioning hole 11 again to fix the position of the movable ruler 2. The angle ruler 3 includes an extension plate 12 arranged at the head end of the fixed ruler 1, a fixed shaft 13 arranged on the outer surface of the extension plate 12, a protractor 14 sleeved on the outside of the fixed shaft 13 and connected to the extension plate 12, and a protractor 15 arranged on the outside of the protractor 14 and rotatably connected to the fixed shaft 13. When measuring the angle, the protractor 15 and the fixed ruler 1 are unfolded, and the angle between the protractor 15 and the fixed ruler 1 is measured by the protractor 14, so that the angle of the drawing can be measured. The fixed ruler 1, the protractor 14 and the protractor 15 are all made of transparent material. By setting the transparent material, it is convenient to measure the angle through the protractor 14. The value of the angle between the protractor 15 and the fixed ruler 1 is observed. A limiting hole 16 is provided on one side of the protractor 15 close to the fixed axis 13. A circular hole corresponding to the limiting hole 16 is provided on the protractor 14. The inner end of the circular hole extends to the inside of the fixed ruler 1, and a plug rod 17 for limiting the protractor 15 is inserted into the inside of the limiting hole 16. The plug rod 17 is magnetically connected to the fixed ruler 1 through a magnet. When the protractor 15 is not in use, the protractor 15 is rotated to a state perpendicular to the fixed ruler 1, and the plug rod 17 is inserted into the circular hole along the limiting hole 16, and connected to the fixed ruler 1 through a magnet, so as not to affect the measurement of the length of the drawing by the fixed ruler 1. A circular groove 18 is provided in the middle of the fixed ruler 1.A fixing rod 19 is provided in the middle of the circular groove 18, and a swivel 20 is rotatably connected to the outer wall of the fixing rod 19.

The two sides of the bottom of the fixed ruler 1 are provided with arc-shaped handles 23 for easy gripping of the fixed ruler 1. By providing the arc-shaped handles 23 at the bottom of the fixed ruler 1, when the fixed ruler 1 is used to measure the length of the drawing, the fixed ruler 1 can be easily moved by gripping the arc-shaped handles 23.

[0033] The working principle and use process of the utility model are as follows: when using the measuring ruler, in order to measure drawings with larger sizes, when the movable ruler 2 is moved out of the fixed ruler 1 along the slide groove 4, the limit rod 8 is pulled outward to release the limit of the movable ruler 2 by the limit rod 8, and the spring 10 is stretched. After the movable ruler 2 moves to the tail end of the slide groove 4, the limit rod 8 is reset and inserted into the insertion hole 9 along the positioning hole 11 again to fix the position of the movable ruler 2, so that the length of the fixed ruler 1 can be extended. When the fixed ruler 1 is used to measure the drawings, when the hanging rope 21 is on the gravity ball 22 When the movable ruler 2 is kept in a vertical state under the action of gravity, the horizontality of the fixed ruler 1 can be judged. After use, the movable ruler 2 can be retracted into the slide groove 4, which is convenient for the staff to carry. When measuring the angle of the drawing, unfold the protractor 15 and the fixed ruler 1, and measure the angle between the protractor 14 and the fixed ruler 1. When the protractor 15 is not in use, rotate the protractor 15 to a state perpendicular to the fixed ruler 1, insert the insertion rod 17 into the circular hole along the limiting hole 16, and connect it to the fixed ruler 1 through a magnet to avoid affecting the measurement of the length of the drawing by the fixed ruler 1.
