Description

Technical Field

[0001] The present disclosure relates to the technical field of stationery, and more particularly, to a measuring tool. Background Art

[0002] Measuring tools play a crucial role in scientific research and daily life. They are not only the basis of scientific research but also an important means to ensure the quality of production and life. For example, in the production process, precise measuring tools can ensure the quality and consistency of products; in the scientific research field, accurate measuring tools can help scientists conduct precise experiments and analyses; in daily life, measuring tools help us better manage and control various resources.

[0003] In daily study and life, length measuring tools often use tools such as straight rulers with straight edges for easy carrying and measurement. Straight rulers can also be used for drawing lines, making drawings, etc., and are widely used in disciplines such as mathematics, measurement, and engineering. Currently, when implementing functions such as measurement or line drawing with measuring tools such as straight rulers, since the straight ruler moves relative to the surface to be measured, it is difficult to accurately determine the relative position between the straight ruler and the surface to be measured during measurement or line drawing, resulting in deviations in line drawing or measurement and a poor user experience.

[0004] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art.

By providing an anti-slip portion on the body, the measuring tool can be fixed to the surface of the object to be measured through the anti-slip portion, improving the accuracy of line drawing or measurement and the use stability of the measuring tool.

[0006] Other features and advantages of the present disclosure will become apparent through the following detailed description, or will be partially learned through the practice of the present disclosure.

However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; on the contrary, these embodiments are provided so that the present disclosure will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted. In addition, the drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0030] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of an icon to another component, these terms are used in this specification only for convenience, for example, according to the directions of the examples described in the drawings. It can be understood that if the device of the icon is turned upside down, the component described as "upper" will become the component described as "lower". When a structure is "on" another structure, it may mean that a structure is integrally formed on another structure, or that a structure is "directly" disposed on another structure, or that a structure is "indirectly" disposed on another structure through another structure.

[0031] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "comprising" and "having" are used to mean an open inclusion and mean that there may be additional elements / components / etc. in addition to the listed elements / components / etc.; the terms "first", "second", "third", etc. are used only as labels and are not a limitation on the quantity of their objects.

[0032] In the related art, a measuring tool refers to a tool used to measure a certain property, including length, angle, temperature, time, mass, force, etc. These tools are widely used in various aspects such as production, scientific research fields and people's lives. And a ruler, as a length measuring tool, is widely used in daily life and study, especially as a tool for assisting in drawing lines and measuring. As a stationery, a ruler is an essential product for every student.

[0033] Whether it is measurement or drawing a line, one surface of the ruler needs to be in contact with and fit the surface of the object to be measured. When the user uses it, there will be displacement between the ruler and the object to be measured, making it difficult to accurately control the ruler and difficult to ensure the accuracy of the relative position between the ruler and the object to be measured, resulting in deviations during line drawing or measurement and reducing the accuracy of ruler use.

[0034] Based on this, the embodiments of the present disclosure provide a measuring tool for an object to be measured, such as Figure 1 shown, in combination with Figure 2 , the measuring tool includes: a body 100 and an anti-slip portion 200.

[0035] Wherein, the body 100 has a through hole 300. The body 100 includes a first surface 101 and a second surface 102 which are oppositely arranged. The through hole 300 penetrates through the first surface 101 and the second surface 102. The first surface 101 is at least in contact with a partial surface of the object to be measured 500; the anti-slip portion 200 is made of an elastic material. The anti-slip portion 200 is embedded in the through hole 300. At least one adsorption portion 210 is arranged on the surface of the anti-slip portion 200 facing the object to be measured 500. The adsorption portion 210 is a hollow structure.

[0036] The measuring tool provided by the present disclosure has an anti-slip portion 200 provided on the body 100 of the measuring tool. The surface of the anti-slip portion 200 has an adsorption portion 210. When using the measuring tool, through the elastic deformation of the anti-slip portion 200, the adsorption portion 210 thereon can adsorb on the surface of the object 500 to be measured, so as to fix the position of the measuring tool, reduce the use error of the measuring tool, and improve the use stability of the measuring tool.

[0037] The following will describe in detail each part of the measuring tool provided by the embodiments of the present disclosure with reference to the accompanying drawings:

[0038] In the embodiment provided by the present disclosure, as Figure 1 shown, the measuring tool includes a body 100. The body 100 has a through hole 300. The body 100 includes a first surface 101 and a second surface 102 arranged opposite to each other. The through hole 300 penetrates the first surface 101 and the second surface 102. The first surface 101 at least fits with a part of the surface of the object 500 to be measured.

[0039] In the present disclosure, the object 500 to be measured can be an object with various materials and shapes such as paper, an object with a flat surface, an object with a curved surface, a metal surface, a porcelain surface, etc. The embodiment provided by the present disclosure takes the object 500 to be measured as paper as an example for description, but the object 500 to be measured includes but is not limited to paper, and the object 500 to be measured not only includes the function of measuring length, but also can have other functions such as drawing lines, which will not be listed one by one here.

[0040] The body 100 can be a rectangular outer shape structure with straight edges on both sides, or a quasi-rectangular structure with a straight edge on one side and a wavy edge on the other side. Among them, the straight edge can be used for drawing a straight line, and the wavy edge can be used for drawing a wavy line. Of course, the two sides of the body 100 can also adopt other different curved lines for drawing different forms of curves, such as a serrated edge, etc.

[0041] Taking the case where one side of the body 100 is a straight edge and the other side is a wavy edge as an example, on one side of the first surface 101 or the second surface 102 of the body 100 close to the straight edge, scale lines can be provided. The scale lines are used to divide the length to facilitate the user to read the measurement data. Among them, the scale lines can be printed on the first surface 101 or the second surface 102 by printing, or engraved on the first surface 101 or the second surface 102 by engraving. The setting of the scale lines can be selected according to the actual design requirements.

[0042] The main body 100 can be made of hard plastic such as ABS material, or can be made of metal such as stainless steel, or can also be made of other materials such as glass and ceramics that can be used to manufacture the main body 100 of the measuring tool. The specific material can be adaptively adjusted according to its usage scenario and design requirements.

[0043] A through hole 300 is provided on the main body 100, such as Figure 1 shown, in combination with Figure 2 , the through hole 300 penetrates the first surface 101 and the second surface 102. Among them, the through hole 300 can be one of various shapes such as a long waist hole, an oval hole, a rectangular hole, a polygonal hole, etc. Taking the long waist hole as an example, the length of the long waist hole can be 30% - 40% of the length of the main body 100, the width of the long waist hole can be 40% - 50% of the width of the main body 100, and the depth of the long waist hole is equal to the thickness of the main body 100. For example, if the main body 100 is a straight ruler with a length of 15 cm (centimeters) and a width of 3 cm, then the length of the long waist hole can be 5 cm - 6 cm, and the width can be 1.2 cm - 1.5 cm.

[0044] In the embodiment provided by the present disclosure, the measuring tool includes an anti-slip portion 200. The anti-slip portion 200 is made of an elastic material. The anti-slip portion 200 is embedded in the through hole 300, and at least one adsorption portion 210 is provided on the surface of the anti-slip portion 200 facing the object 500 to be measured. The adsorption portion 210 is a hollow structure.

[0045] Among them, the anti-slip portion 200 is made of an elastic material, and it can have elastic deformation under the action of an external force. After the external force disappears, it can return to its original shape. For example, the anti-slip portion 200 can be made of materials such as silica gel, rubber, and polyurethane elastomer.

[0046] The anti-slip portion 200 is embedded in the through hole 300 of the main body 100, and the anti-slip portion 200 can be integrally formed with the main body 100. For example, when manufacturing the measuring tool, after forming the main body 100, the anti-slip portion 200 can be directly formed on the main body 100 with the through hole 300 by an injection molding process. During subsequent use, since the anti-slip portion 200 is integrally formed with the main body 100, it is avoided that the anti-slip portion 200 falls off from the main body 100, and the durability of the anti-slip portion 200 is improved. Or the anti-slip portion 200 is a detachable structure. After it and the main body 100 are separately manufactured and formed, the anti-slip portion 200 is installed in the through hole 300 of the main body 100. Among them, the protective portion and the main body 100 can be connected by means of clamping or bonding, etc. During long-term use, after the anti-slip portion 200 is damaged, the damaged anti-slip portion 200 can be removed from the main body 100 and replaced with a new anti-slip portion 200, which increases the service life of the main body 100 and improves the utilization rate of the main body 100.

[0047] Among them, such as Figures 3 to 5As shown, one side of the anti-slip portion 200 facing the object 500 to be measured is flush with the first surface 101; or one side of the anti-slip portion 200 facing the object 500 to be measured is recessed from the first surface 101. To ensure that there is no gap between the first surface 101 of the main body 100 and the surface of the object 500 to be measured, which may affect the measurement or line-drawing accuracy, generally, the side of the anti-slip portion 200 in contact with the object 500 to be measured is not protruded from the first surface 101. Specifically, the side of the anti-slip portion 200 in contact with the object 500 to be measured can be flush with the first surface 101, so that when the first surface 101 is in contact with the surface of the object 500 to be measured, the surface of the anti-slip portion 200 is also in contact with the surface of the object 500 to be measured; or the side of the anti-slip portion 200 in contact with the object 500 to be measured is recessed from the first surface 101. When the first surface 101 is in contact with the surface of the object 500 to be measured, there is a gap between the surface of the anti-slip portion 200 and the surface of the object 500 to be measured, so that when the anti-slip portion 200 undergoes elastic deformation later, enough deformation space is provided for the anti-slip portion 200 to generate enough adsorption force.

[0048] As Figures 3 to 5 shown, one side of the anti-slip portion 200 away from the object 500 to be measured is flush with the second surface 102; or one side of the anti-slip portion 200 away from the object 500 to be measured protrudes from the second surface 102. To ensure that the setting of the anti-slip portion 200 does not affect the measurement or line-drawing functions of the measuring tool, generally, the side of the anti-slip portion 200 away from the object 500 to be measured is not recessed from the second surface 102. Specifically, the side of the anti-slip portion 200 away from the object 500 to be measured can be flush with the second surface 102; or one side of the anti-slip portion 200 away from the object 500 to be measured protrudes from the second surface 102, so that when the first surface 101 of the main body 100 is in contact with the surface of the object 500 to be measured, there is a gap between the surface of the anti-slip portion 200 and the surface of the object 500 to be measured, so that when the anti-slip portion 200 undergoes elastic deformation later, enough deformation space is provided for the anti-slip portion 200 to generate enough adsorption force. At the same time, the anti-slip portion 200 protrudes from the second surface 102, which is convenient for the user to apply force to the anti-slip portion 200 and ensures that enough external force is provided for the elastic deformation of the anti-slip portion 200. In addition, through the setting of different surfaces of the anti-slip portion 200, it can also provide the user with the difference between the front and back sides of the measuring tool, improving the user experience.

[0049] In the length direction of the main body 100, as Figure 3As shown, the length L2 of the anti-slip part is 30% - 40% of the length L1 of the body, such as 30%, 32%, 34%, 36%, 38% or 40%, etc. Taking the length L1 of the body as 15 cm as an example, the length L2 of the anti-slip part can be 4.5 cm - 6 cm. For example, it can be 4.5 cm, 5 cm, 5.5 cm or 6 cm, etc. Taking the length L1 of the body as 20 cm as an example, the length L2 of the anti-slip part can be 6 cm - 8 cm. For example, it can be 6 cm, 6.5 cm, 7 cm, 7.5 cm or 8 cm, etc. According to the different length L1 of the body of the measuring tool, the length L2 of the anti-slip part can be adjusted appropriately. However, the length L2 of the anti-slip part should not be too long, so as not to reduce the strength of the body 100. The length L2 of the anti-slip part should not be too short either, so as not to make it difficult for the anti-slip part 200 to produce elastic deformation. When the length L2 of the anti-slip part is 30% - 40% of the length L1 of the body, it not only ensures sufficient elastic deformation space but also can ensure the strength of the body 100.

[0050] In the width direction of the body 100, as Figure 4 shown, the width W2 of the anti-slip part is 40% - 50% of the width W1 of the body, such as 40%, 42%, 44%, 46%, 48% or 50%, etc. Taking the width W1 of the body as 3.1 cm as an example, the width W2 of the anti-slip part can be 1.2 cm - 1.5 cm. For example, it can be 1.2 cm, 1.3 cm, 1.4 cm or 1.5 cm, etc. According to the different width W1 of the body of the measuring tool, the width W2 of the anti-slip part can be adjusted appropriately. However, the width W2 of the anti-slip part should not be too large, so as not to reduce the strength of the body 100. The width W2 of the anti-slip part should not be too small either, so as not to make it difficult for the anti-slip part 200 to produce elastic deformation. When the width W2 of the anti-slip part is 40% - 50% of the width W1 of the body, it not only ensures sufficient elastic deformation space but also can ensure the strength of the body 100.

[0051] Among them, at least one adsorption part 210 is arranged on the surface of the anti-slip part 200 facing the object to be measured 500, and the adsorption part 210 is a hollow structure. By applying an external force to the anti-slip part 200 for a period of time, the adsorption part 210 can be deformed. When the adsorption part 210 presses on the surface of the object to be measured 500, the air in the hollow structure of the adsorption part 210 is discharged, making the adsorption part 210 in a vacuum state. The external atmospheric pressure is higher than the air pressure inside the adsorption part 210, so that the anti-slip part 200 is adsorbed on the surface of the object to be measured 500 through the adsorption part 210, preventing the measuring tool from moving during use.

[0052] The adsorption part 210 can be in the structure of a hollow cylinder, as Figure 1 shown, combined with Figure 3, the outer diameter D of each adsorption part is 4% to 6% of the length L1 of the body, such as 4%, 4.5%, 5%, 5.5% or 6%. Taking the length L1 of the body as 15 cm as an example, the outer diameter D of the adsorption part can be 0.6 cm to 0.9 cm, for example, 0.6 cm, 0.7 cm, 0.8 cm or 0.9 cm. Taking the length L1 of the body as 20 cm as an example, the outer diameter D of the adsorption part can be 0.8 cm to 1.2 cm, for example, 0.8 cm, 0.9 cm, 1 cm, 1.1 cm or 1.2 cm. According to the length L1 of the body of the measuring tool, the outer diameter D of the adsorption part can be appropriately adjusted. The outer diameter D of the adsorption part within the above range can not only ensure the adsorption effect of each adsorption part 210 under elastic deformation, but also ensure that no large force will be used when separating the measuring tool and the object to be measured 500 in the future, thereby avoiding damage to the object to be measured 500 or the measuring tool. In addition, the adsorption part 210 adopts the above-mentioned size, so that the contact area between the adsorption part 210 and the surface of the object to be measured 500 is small, preventing the adsorption part 210 from having more contact with the painting handwriting when the user uses the measuring tool to draw, etc., causing dirt on the surface of the object to be measured 500.

[0053] The number of the adsorption parts 210 is at least one, and can generally be multiple, wherein the multiple adsorption parts 210 can all be hollow cylindrical structures, and the outer diameters D of the multiple adsorption parts can be the same or different, and their sizes can be selected and adjusted according to the shape and structure of the anti-slip part 200. In addition, the adsorption part 210 can also be a hollow cuboid, a hollow prism, and other external structures, which can be selected according to actual design requirements. Specifically, the number of adsorption parts 210 can be 4 to 6, such as Figure 1 As shown, there may be 4, 5 or 6 adsorption parts 210 arranged side by side along the length direction of the anti-slip part 200. This arrangement can ensure that when an external force acts on any part of the anti-slip part 200, there is an adsorption part 210 that can provide adsorption. Of course, the multiple adsorption parts 210 can also be arranged on one side of the anti-slip part 200 in other ways such as array distribution, which can be adjusted according to actual design requirements.

[0054] In order to increase the friction force and improve the user's feeling of use, a plurality of protrusion structures 400 are arranged on the side of the anti-slip portion 200 away from the object to be measured 500. The plurality of protrusion structures 400 are arranged in an array, such as Figure 2 The size of the protrusion structure 400 is much smaller than the surface area of the anti-slip part 200. For example, the protrusion structure 400 may be a brush protrusion, and a plurality of brush protrusions are distributed on the side of the anti-slip part 200 away from the object to be measured 500. When an external force is applied to the anti-slip part 200, the protrusion structure 400 can increase the friction force, making it easier for the user to apply force.

[0055] It should be noted that, in the above embodiments of the present disclosure, a straight ruler is taken as an example for the measuring tool, but the measuring tool is not limited to a straight ruler, and it can also be a protractor, a folding ruler, a triangular plate, etc. By making adaptive adjustments or deformations to the anti-slip portion 200 provided by the present disclosure according to different parameters such as shape or size, they are all within the protection scope of the present disclosure.

[0056] For the measuring tool provided by the present disclosure, by providing the anti-slip portion 200 on the body 100 of the measuring tool, and the adsorption portion 210 is provided on the surface of the anti-slip portion 200. When using the measuring tool, through the elastic deformation of the anti-slip portion 200, the adsorption portion 210 thereon can adsorb on the surface of the object 500 to be measured, so as to fix the position of the measuring tool, reduce the use error of the measuring tool, and improve the use stability of the measuring tool.

[0057] Those skilled in the art will readily conceive of other embodiments of the present disclosure after considering the specification and practicing the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present disclosure, which follow the general principles of the present disclosure and include known common knowledge or conventional technical means in the technical field not disclosed by the present disclosure.
