[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-6 This utility model provides a technical solution for a multifunctional ruler that can measure angles:
[0022] A multi-functional ruler capable of measuring angles includes a rectangular ruler plate 1, on which a first through groove 2, a second through groove 3, a third through groove 4, and a fourth through groove 5 are provided; wherein the first through groove 2 and the fourth through groove 5 are located at the bottom left and right sides of the ruler plate 1, respectively, the second through groove 3 and the third through groove 4 are located at the top and bottom sides of the ruler plate 1, respectively, and the third through groove 4 and the fourth through groove 5 are connected.
[0023] This results in the following edges appearing on ruler 1: first edge 1.1, second edge 1.2, third edge 1.3, fourth edge 1.4, fifth edge 1.5, sixth edge 1.6, seventh edge 1.7, first inner vertex angle 1.8, second inner vertex angle 1.9, first outer vertex angle 1.10, second outer vertex angle 1.11, and third outer vertex angle 1.12; wherein the second edge 1.2 and the fourth edge 1.4 are collinear, the included angle of the third outer vertex angle 1.12 is 45°, and the first inner vertex angle 1.8 is located on the second inner vertex angle 1.7. The first inner vertex 1.8 and the first outer vertex 1.10 are directly above the second outer vertex 1.11 and have the same angle. The first inner vertex 1.8 and the first outer vertex 1.10 are alternate interior angles, and the second inner vertex 1.9 and the second outer vertex 1.11 are also alternate interior angles. Therefore, the first inner vertex 1.8, the second inner vertex 1.9, the first outer vertex 1.10, and the second outer vertex 1.11 all have the same angle of 30°, laying the foundation for the subsequent combined use of the two rulers.
[0024] like Figure 1 , Figure 5 and Figure 6 As shown, graduation values are engraved on the first edge 1.1 and the second edge 1.2 of the ruler 1. The first edge 1.1 is engraved with a 20-degree graduation value, and the second edge 1.2 is engraved with a 10-degree graduation value, which are used as verniers. When using the second ruler, the first edge 1.1 or the second edge 1.2 of the first ruler is placed against the third edge 1.3 of the second ruler, and the object to be measured 6 is held between the two rulers, so that the diameter of the object to be measured 6 can be measured.
[0025] like Figure 1 and Figure 4 As shown, length scale values are engraved on the third edge 1.3 and the fourth edge 1.4 of the ruler 1 for drawing lines and lengths. When using the second ruler, the fourth edge 1.4 of the first ruler is placed against the third edge 1.3 of the second ruler. At this time, some small objects to be measured 6 can be placed in the gap between the first outer apex 1.10 of the first ruler and the first inner apex 1.8 of the second ruler for clamping and measurement. By using the length scale value D at the position of the tip of the first outer apex 1.10 of the first ruler on the third edge 1.3 of the second ruler, the diameter of the object to be measured 6 can be obtained by using trigonometric functions = D·sin30°.
[0026] like Figure 1 , Figure 2 and Figure 3 As shown, angle scale values are engraved on the left side surface of ruler 1, the sixth edge 1.6, and the seventh edge 1.7.
[0027] The angle scale on the left side of ruler 1 is in a fan-shaped structure, divided into a first fan-shaped scale line 1.01 and a second fan-shaped scale line 1.02. The first fan-shaped scale line 1.01 is located to the right of the second fan-shaped scale line 1.02, and the center of the first fan-shaped scale line 1.01 is located to the left of the third edge 1.3 at the 0-degree mark. When using the second ruler, the seventh edge 1.7 of the first ruler is aligned with the third edge 1.3 of the second ruler, and the second outer apex angle 1.11 of the first ruler is inserted into the first inner apex angle 1.8 of the second ruler. At this time, the first fan-shaped scale line 1.01 of the first ruler and the second fan-shaped scale line 1.02 of the second ruler will form a 90° protractor scale line, which can be used for angle measurement.
[0028] When using the second ruler, align the fifth edge (1.5) of the first ruler with the third edge (1.3) of the second ruler. Insert the third outer apex (1.12) of the first ruler into the first inner apex (1.8) of the second ruler. At this point, the left-hand graduation (1) on the third edge (1.3) of the second ruler coincides with the center of the angle graduations on the sixth and seventh edges (1.6 and 1.7). Using this center as a starting point, find the corresponding angle graduation on the first ruler based on the angle you are drawing to quickly draw the corresponding angle line.
[0029] This product has an overall length of no more than 190mm and a width of no more than 25mm, making it easy to fit into a file box. It can also draw length lines, measure angles, and has the function of a vernier caliper. It can draw lines at the required angles. It has diverse functions, a simple structure, and is easy to process and produce.
[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
