Abstract
Description
Technical fields:
[0002] This utility model relates to the field of measuring tool technology, specifically a combined vernier length measuring structure. Background technology:
[0004] Students face a multitude of learning tools. Students frequently encounter various measuring tools during their daily studies. For example, in junior high school, students learn to use vernier calipers; however, this learning period lasts only a few weeks. Some impoverished schools cannot afford to purchase teaching aids in bulk, making it impossible to provide each student with one. Furthermore, these calipers are collected after class, forcing students to practice in groups, or even learn by reading diagrams, thus reducing learning efficiency. While students can purchase vernier calipers individually, this significantly increases procurement costs, shortens the learning period, and makes the organization, storage, and transport of the tools extremely inconvenient, creating unnecessary trouble and cost burdens for students and reducing learning efficiency and teaching quality. Additionally, the difficulty in aligning the multiple graduations on a standard 50-division vernier caliper is a major problem. In conclusion, the lack of hands-on practice with vernier calipers is the biggest obstacle for students learning to use them. Utility Model Content:
[0006] The purpose of this invention is to provide a combined vernier length measuring structure to solve the problems mentioned in the background art.
[0007] This utility model is implemented by the following technical solution:
[0008] A combined vernier length measuring structure includes an independent plate-shaped first structure and a second structure with their edges fitting together. The first structure includes at least four straight edges connected end-to-end, and has at least one concave corner formed by two edges. A length scale mark is provided on one of the straight edges in the horizontal direction of the concave corner. The second structure includes at least three straight edges connected end-to-end, and has at least one convex corner formed by two straight edges. A vernier scale mark is provided on one of the straight edges in the horizontal direction of the convex corner. Both the length scale mark and the vernier scale mark consist of multiple evenly distributed scale lines. The concave and convex corners are both right angles. One edge in the horizontal direction of the concave corner and one edge in the horizontal direction of the convex corner fit together and slide against each other.
[0009] Preferably, both the concave and convex angles are right angles, and both the first and second structures are independent plate-shaped structures.
[0010] Preferably, the first structure includes four straight edges connected end to end, and the whole is formed by splicing two triangles together to form four straight edges, two of which form concave angles; the second structure includes three straight edges connected end to end, and the whole is a right triangle, two of which form convex angles.
[0011] Preferably, the first structure includes six straight edges connected end to end, two of the straight edges of the first structure form a concave angle, and the other two straight edges that are parallel to the two straight edges that form the concave angle form a convex angle. The second structure is the same as the first structure.
[0012] Preferably, the vernier scale is marked in 10, 20, or 50 divisions.
[0013] Preferably, because the precision of mechanical manufacturing is higher than that of printing, the scale lines are engraved on the surface of the structure to form indentations.
[0014] The advantages of this invention are: it adopts the principle of vernier calipers, and through the cooperation between the first and second structures, it can effectively improve the measurement accuracy of length compared with existing rulers.
[0015] This product utilizes four edges and a concave corner, corresponding to different scales. Users can easily switch between two ruler modes, requiring only one tool to fully satisfy students' learning needs for vernier calipers. Of course, the same effect can be achieved by using more edges. However, the core R&D investment of this utility model patent focuses on structural simplification. The simpler the structure of an object, the more prominent its integrability becomes, significantly improving its compatibility with different products. In cases with strict requirements on the number of sides or shape, it can be embedded into various other products as much as possible, greatly facilitating secondary development. Particularly noteworthy is the significant improvement in both measurement accuracy and ease of use compared to conventional measuring tools of the same type. The overall structure is simple, with no moving parts, making it less prone to damage. Due to the low production cost and small size of the ruler, it achieves high measurement accuracy. The vernier caliper function is integrated into a regular ruler, eliminating the need to increase the purchase cost while still including the vernier function, allowing every student to practice with vernier calipers. At the same time, its simple structure makes it easy to store, carry, and manufacture. This addresses the issue of students carrying a wide variety of stationery and incurring high purchase costs.
[0016] Secondly, the design of the concave graduations avoids the problem of multiple graduation lines aligning and affecting the accuracy of the graduations due to factors such as printing precision and limited visual observation capabilities.
[0017] Secondly, due to its low production cost and low purchasing pressure, students can use this ruler to learn vernier caliper measurement, making the combination of learning and practice a reality. Attached image description:

[0020] Figure 2 This is a reference diagram of the combined state of Example 2.
[0021] In the diagram: 1. First structure, 2. Second structure, 3. Length scale mark, 4. Vernier scale mark, 5. Concave corner, 6. Convex corner. Detailed implementation method:
[0023] 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.
[0024] The straight edge mentioned in this utility model is the simplest form expressed using a straight edge. Whenever an arc edge is used to replace a straight edge, it is considered that the arc edge is composed of countless straight edges, which is an equivalent substitution.
[0025] The concave and convex angles formed by the two edges mentioned in this utility model are the simplest forms. Any addition of other edges between the concave and convex angles is considered an equivalent substitution.
[0026] Please see Figure 1-2 This utility model provides a technical solution for a combined vernier length measuring structure:
[0027] Example 1
[0028] Please see Figure 1A combined vernier length measuring structure includes an independent plate-shaped first structure 1 and a second structure 2 with their edges fitting together; both the first structure 1 and the second structure 2 are independent plate-shaped structures. The first structure 1 includes four straight edges connected end to end, and is formed by two triangles spliced together to form the four straight edges, two of which form a concave angle 5; the concave angle 5 is formed by two straight edges, and a length scale mark 3 is provided on one of the straight edges in the horizontal direction of the concave angle 5; the second structure 2 includes three straight edges connected end to end, forming a right-angled triangle, two of which form a convex angle 6, and a vernier scale mark 4 is provided on one of the straight edges in the horizontal direction of the convex angle 6; both the length scale mark 3 and the vernier scale mark 4 are composed of multiple evenly distributed scale lines, and both the concave angle 5 and the convex angle 6 are right angles. The second structure 2 and the first structure 1 are placed on the same bearing plane, and one edge in the horizontal direction of the concave angle 5 and one edge in the horizontal direction of the convex angle 6 fit together and slide against each other. The scale lines are formed by indentations engraved on the surface of the structure, and all the indentations have the same width and depth.
[0029] The vernier scale marking 4 is 10 divisions, 20 divisions, or 50 divisions; in this embodiment, 10 divisions are used.
[0030] The method for measuring length includes the following steps:
[0031] Step 1: Locate the first structure 1 or the second structure 2 with length scale mark 3 and vernier scale mark 4. For example, if the first structure 1 has length scale mark 3, then the second structure 2 must have vernier scale mark 4.
[0032] Step 2: Place the first structure 1 and the second structure 2 on the same bearing plane, and align the convex corner 6 of the second structure 2 with the concave corner 5 of the first structure 1 so that the "0" scale line of the length scale mark 3 of the first structure 1 and the "0" scale line of the vernier scale mark 4 of the second structure 2 are aligned, thus completing the splicing between the first structure 1 and the second structure 2.
[0033] Step 3: Then slide the second structure 2 so that the convex corner 6 and the concave corner 5 gradually move away from each other, and clamp the object to be measured through the edges where the two "0" scale lines are located;
[0034] Step 4: After clamping, use a sharp object that can be inserted into the indentation of the scale mark to slide from the inside of the indentation of the minute scale mark to the inside of the indentation of the length scale mark. If it gets stuck at the edge of the minute scale mark, it means that it is not aligned. When it gets to the edge of the minute scale mark with the smallest sticking, it means that a certain scale line of the minute scale mark is aligned with a certain scale line of the length scale mark, which makes it easy to read.
[0035] Step 5: By observing the reading on the vernier caliper, you can determine the length of the object being measured.
[0036] Example 2
[0037] Please see Figure 2 and Figure 1 Compared with Example 1, Example 2 uses the same method. The difference is that the first structure 1 includes six straight edges connected end to end. Two of the straight edges of the first structure 1 form a concave angle 5. A length scale mark 3 is provided on one of the straight edges in the horizontal direction of the concave angle 5. The other two straight edges, which are parallel to the two straight edges that form the concave angle 5, form a convex angle 6. A vernier scale mark 4 is provided on one of the straight edges in the horizontal direction of the convex angle 6. Both the length scale mark 3 and the vernier scale mark 4 are composed of multiple evenly distributed scale lines. The second structure 2 is the same as the first structure 1.
[0038] The vernier scale marking 4 is 10 divisions, 20 divisions, or 50 divisions; in this embodiment, 50 divisions are used.
[0039] 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.
