Description

Technical Field

[0001] This application relates to the technical field of multifunctional rulers, and particularly to a multifunctional ruler. Background Art

[0002] Rulers are one of the essential stationery items for students during the learning process. In our daily lives, rulers are almost everywhere. In math classes during our student days, we use straight rulers to draw neat figures; when decorating houses, workers use tape measures to accurately measure the dimensions of each piece of board; in the field of fashion design, designers use flexible rulers to take body measurements to ensure the fit and beauty of the clothing. The existence of rulers makes our lives more orderly and precise. Students often encounter problems with insufficient ruler length during the drawing process, resulting in poor drawing quality and long time consumption. Sometimes, they need to rotate at certain angles for marking or drawing, but traditional rulers are not suitable for adjustment and angle rotation, and for increasing the ruler length. Not only in the classroom, sometimes when measuring an object on its side with an uneven surface, a level needs to be added to the ruler before trimming the object. The level bubble is directly fixed on the ruler, but this installation method is not conducive to disassembly and replacement. Utility Model Content

Specific implementation mode

[0018] The following will further elaborate on this application in conjunction with the attached Figures 1-4 drawings.

[0019] An embodiment of this application discloses a multifunctional ruler. Referring to Figure 1 and Figure 2 , it includes the first ruler 1. On both sides of the first ruler 1, there are fixedly connected the first rotating blocks 2. The thickness of the first rotating block 2 is half of that of the first ruler 1. The two first rotating blocks 2 are located in the lower half of the thickness of the first ruler 1. One side of the first rotating block 2 is hinged to the second rotating block 3. One side of the second rotating block 3 is fixedly connected to the second ruler 4. The thickness of the second rotating block 3 is half of that of the second ruler 4. The second rotating block 3 is located in the upper half of the thickness of the second ruler 4. One side of the second ruler 4 is fixedly connected to another second rotating block 3. The bottom surface of the second rotating block 3 is hinged to the third rotating block 5. By placing the second rotating block 3 on the first rotating block 2 and then connecting the second rotating block 3 and the first rotating block 2 through a connecting piece, rotating the first rotating block 2 or the second rotating block 3 around the connecting piece can further rotate the first ruler 1 or the second ruler 4, changing the angle between the first ruler 1 and the second ruler 4. By continuously adjusting the angle, the thickness of the first rotating block 2 and the second rotating block 3 is equal to the thickness of the first ruler 1 or the second ruler 4. When drawing a line along the first ruler 1 or the second ruler 4 with a pen, the first ruler 1 or the second ruler 4 is on the same horizontal line with a unified thickness, which is convenient for drawing lines without layers. When drawing from the first ruler 1 to a horizontal line at the same height as the second ruler 4, the connecting piece can limit the rotation of the first ruler 1 and the second ruler 4 by rotating the outer ring.

[0020] Referring to Figure 1 , one side of the third rotating block 5 is hinged to the third ruler 6. The third rotating block 5 is located in the lower half of the thickness of the third ruler 6. One side of the third ruler 6 is fixedly connected to another third rotating block 5. The top surface of the third rotating block 5 is hinged to the fourth rotating block 7. One side of the fourth rotating block 7 is fixedly connected to the fourth ruler 8. The fourth rotating block 7 is located in the upper half of the thickness of the fourth ruler 8. One side of the fourth ruler 8 is fixedly connected to another fourth rotating block 7. The bottom surface of the other fourth rotating block 7 is hinged to the first rotating block 2. By placing the third rotating block 5 on the bottom surface of the second rotating block 3 and connecting the second rotating block 3 and the third rotating block 5 through a connecting piece, rotating the third rotating block 5 or the second rotating block 3 can change the angle between the third rotating block 5 and the second rotating block 3 to the required angle.

[0021] Referring to Figure 4, on one side of the ruler one 1, ruler two 4, ruler three 6, and ruler four 8, there is a snap connection with a spirit level handle 9. A hole is provided in the middle of the spirit level handle 9. A threaded hole is provided on one side of the spirit level handle 9. A screw rod 10 is threadedly connected to one side of the spirit level handle 9. One end of the screw rod 10 passes through the outside of the threaded hole and is connected to the ruler one 1, or ruler two 4, ruler three 6, or ruler four 8. The other end of the screw rod 10 is threadedly connected to a nut 11, and the nut 11 plays a limiting role on the screw rod 10.

[0022] Refer to Figure 4 , a bayonet is provided on one side of the spirit level handle 9. Convex card holes are provided on one side of the ruler one 1, ruler two 4, ruler three 6, and ruler four 8. One end of the screw rod 10 is fixedly connected to a connecting block. One end of the connecting block is fixedly connected to a convex card block 12. One side of the convex card block 12 is located on one side of the bayonet of the spirit level handle 9. By passing the screw rod 10 through the threaded hole of the spirit level handle 9, the connecting block is attached to the inner wall of the hole of the spirit level handle 9, so that the front elevation of the convex card block 12 forms a ninety-degree angle with the inner wall of the hole of the spirit level handle 9. The bayonets of the spirit level handle 9 move along the inner walls of the convex card holes of the ruler one 1, ruler two 4, ruler three 6, and ruler four 8 respectively, so that the convex card block 12 moves along the convex card hole, achieving the function of convenient disassembly and assembly.

[0023] Refer to Figure 3 and Figure 4 , a square hole is provided on the top surface of the spirit level handle 9. A spirit level 13 is fixedly connected to the inner wall of the square hole. When the ruler one 1, ruler two 4, ruler three 6, and ruler four 8 rotate, when they are close to the wall surface or the outside of an object, the surface is uneven. It is necessary to level it through the spirit level 13 and carefully observe whether the bubble in the spirit level is within the central scale line. If the bubble is completely centered, it means the object is in a horizontal state; if the bubble deviates to one side, it means the object is tilted, and adjustment needs to be made according to the direction of the bubble deviation. Place the ruler one 1, or ruler two 4, ruler three 6, or ruler four 8 close to the object, and then observe which side the bubble of the spirit level 13 deviates to, to detect the flatness of the surface of the item.

[0024] The implementation principle of a multifunctional ruler in an embodiment of this application is as follows: First, place the second rotating block 3 on the first rotating block 2, then connect the second rotating block 3 and the first rotating block 2 through a connecting piece, and rotate the first rotating block 2 or the second rotating block 3 around the connecting piece, further enabling the first ruler 1 or the second ruler 4 to rotate, and the included angle between the first ruler 1 and the second ruler 4 is changed. Continuously adjust the angle. Secondly, place the third rotating block 5 on the bottom surface of the second rotating block 3, connect the second rotating block 3 and the third rotating block 5 through a connecting piece, and by rotating the third rotating block 5 or the second rotating block 3, the included angle between the third rotating block 5 and the second rotating block 3 is changed, and rotate to the required angle. Finally, pass the screw 10 through the threaded hole of the spirit level handle 9, make the connecting block fit along the inner side wall of the hole position of the spirit level handle 9, so that the front elevation of the convex-shaped block 12 forms a 90-degree angle with the inner side wall of the hole position of the spirit level handle 9, and the bayonets of the spirit level handle 9 move along the inner side walls of the convex-shaped card holes of the first ruler 1, the second ruler 4, the third ruler 6, and the fourth ruler 8 respectively, so that the convex-shaped block 12 moves along the convex-shaped card hole, achieving the effect of facilitating disassembly and assembly.
