[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] Reference Figures 1-3 This utility model provides a technical solution: an improved modular ruler, including a first ruler body 1 and a second ruler body 2, the second ruler body 2 being located on the back of the first ruler body 1, and an mounting plate 3 being provided on the inner side of the first ruler body 1 and the second ruler body 2. It also includes a snap-fit mechanism, which can connect the first ruler body 1 and the second ruler body 2 through the snap-fit mechanism. After assembling the first ruler body 1 and the second ruler body 2, the mounting plate 3 can be installed. The ruler can be adapted to the usage environment by replacing the mounting plate 3. Moreover, the scale on the first ruler body 1 is laser-engraved or printed inside the ruler, rather than printed on the surface of the ruler, thereby improving the durability of the ruler scale.
[0025] Reference Figures 1-3 In a preferred embodiment, a snap-fit mechanism is provided, which includes a snap-fit groove 4 and a snap-fit member 5. The snap-fit groove 4 is located on the back of the first ruler 1, and the snap-fit member 5 is installed on the front of the second ruler 2. The snap-fit member 5 engages with the snap-fit groove 4, allowing the first ruler 1 and the second ruler 2 to be combined after the snap-fit member 5 is inserted into the snap-fit groove 4. The mounting plate 3 can be installed on the inside of the first ruler 1 and the second ruler 2, and the first ruler 1 and the second ruler 2 can be disassembled, improving the convenience of using and replacing the mounting plate 3. This allows users to easily replace the mounting plate 3 with the corresponding type according to the content of their painting, reducing the hassle of users having to carry many rulers.
[0026] Reference Figures 1-3 In a preferred embodiment, a first mounting part 6 is installed on the right side of the second ruler 2, and a second mounting part 7 is installed on the left side of the second ruler 2. The first mounting part 6 and the second mounting part 7 can block the first ruler 1, preventing the first ruler 1 from being squeezed and deviated during drawing. A sliding groove 8 is provided on the left side of the first mounting part 6, and a sliding plate 9 is slidably installed on the inner wall of the sliding groove 8. A moving groove 10 is provided on the top of the first mounting part 6, and a moving plate 11 is installed on the top of the sliding plate 9. The moving plate 11 slides and engages with the moving groove 10, so that when the moving plate 11 is moved forward, the moving plate 11 can drive the sliding plate 9 to move in the sliding groove 8, thereby blocking the pen drawn from the starting point, making it convenient for the user to start drawing from the "0" position without spending time aligning the "0" position.
[0027] Reference Figures 1-2 In a preferred embodiment, a first notch 12 is provided on the front side of the bottom of the first ruler 1, and a second notch 13 is provided on the rear side of the bottom of the second ruler 2. This can appropriately raise the bottom of the first ruler 1 and the second ruler 2. When drawing against the first ruler 1, the pen tip will avoid directly contacting the edge of the first ruler 1, but the upper part of the pen tip will rest against the ruler, thus preventing ink residue on the first ruler 1. The appropriate increase in height also allows the first ruler 1 and the second ruler 2 to form a certain gap with the table, making it easier for the user to pick up the ruler from the flat surface. This prevents ink residue on the first ruler 1 from easily staining the picture and getting fingers dirty, and contaminated fingers can also easily stain the picture.
[0028] Reference Figures 1-3 In a preferred embodiment, both the surface of the first ruler 1 and the surface of the second ruler 2 are coated with an anti-reflective coating, which facilitates clearer reading of the scale when the ruler is used in a brightly lit environment, improving measurement accuracy. The first ruler 1, the mounting plate 3, and the second ruler 2 are made of acrylic material. The acrylic material of the first ruler 1, the mounting plate 3, and the second ruler 2 has a smooth surface, making it difficult for eraser debris to adhere. It is lightweight and transparent, suitable for drawing, and can also prevent the ruler from sticking together with other erasers when placed together for a long time. Some areas of the ruler surface are treated with a frosted anti-slip texture to increase the friction between the ruler and the hand and prevent slippage.
[0029] Specifically, the working process or principle of this improved modular ruler is as follows: When in use, the templated mounting plate 3 is placed on the second ruler body 2. The snap-fit groove 4 on the back of the first ruler body 1 is aligned with the snap-fit piece 5 on the second ruler body 2. Then, when the first ruler body 1 and the second ruler body 2 are moved inward, the snap-fit piece 5 is inserted into the snap-fit groove 4, and the first ruler body 1 and the second ruler body 2 are engaged to install the mounting plate 3. When drawing from the initial mark with a pen, the moving plate 11 is moved forward, which drives the sliding plate 9 to move, making it easier to press the upper part of the pen tip against the sliding plate 9, which facilitates drawing from the initial mark. When the mounting plate 3 needs to be disassembled and replaced, the first ruler body 1 and the second ruler body 2 are pulled outward to separate the first ruler body 1 and the second ruler body 2. Then the mounting plate 3 is disassembled and replaced with a mounting plate 3 of the type corresponding to the drawing content.
