Description

Technical Field

[0001] This utility model relates to the field of measuring tool technology, and in particular to a multifunctional measuring ruler. Background Technology

[0002] Currently, in the fields of civil engineering, construction, and manufacturing, traditional measuring rulers do not have precise positioning functions. Since the ruler itself is not a fixed integrated structure with the operator's hand, to achieve the positioning function, one hand needs to hold the ruler and the other hand needs to hold a pen to draw points or lines on the edge of the ruler. This often results in situations where the ruler is not held level or the pen is not held firmly, leading to errors in the drawn points or lines. In addition, relying on the method of drawing points or lines on the edge of the ruler is also prone to accuracy errors.

[0003] To address the aforementioned issues, existing technology proposes a positioning ruler with a calibration pen function. Based on a body with a translational shaft hole and a scale gauge, it achieves precise length measurement through a locator that can slide along the shaft hole. The calibration pen on the locator can mark corresponding scales on the measurement surface, while the level on the body is used to confirm whether the ruler is in a horizontal state.

[0004] However, existing technology still cannot meet the needs of drawing arcs in building construction or manufacturing, or the need to draw arcs at specified angles on a vertical reference plane. Users need to carry additional tools such as protractors and compasses, which increases the burden of carrying them and may also lead to cumbersome operation and error accumulation due to tool switching.

[0005] Therefore, there is an urgent need to develop a multifunctional measuring ruler to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a multifunctional measuring ruler that integrates the functions of positioning, drawing lines, drawing arcs, and drawing arcs at specified angles on a vertical reference plane, thus solving the problems of frequent tool switching, cumbersome operation, and accumulated errors during construction.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] Multifunctional measuring ruler, including:

[0009] The ruler body has a groove extending through it along its thickness direction, and the groove extends along the length direction of the ruler body. The ruler body has scale lines parallel to the groove.

[0010] The origin component is at least partially protruding from the surface of the ruler body;

[0011] The marking assembly includes a positioning seat and a marking device. The positioning seat is disposed in the slide groove and can slide along the length direction of the slide groove. The marking device is adjusted to pass through the positioning seat along the thickness direction of the ruler body.

[0012] An angle measuring instrument, fixedly installed on the ruler body, includes a circular transparent shell and an indicator movably installed inside the transparent shell. An angle scale ring is provided around the transparent shell on the ruler body, and when the ruler body is against a vertical reference plane, the indicator rotates with the ruler body.

[0013] Preferably, the origin component is slidably disposed on the groove.

[0014] Preferably, the ruler body is provided with a locking element for locking the position of the origin component on the slide groove.

[0015] Preferably, the indicator includes an indicator liquid, which is sealed within the transparent housing.

[0016] Preferably, the marker includes a connecting rod, a pressing cap, a marking pin, and an elastic element. The connecting rod is screwed to the positioning seat and has a telescopic cavity extending through it along the axial direction. One end of the marking pin is connected to the pressing cap, and the other end extends into the telescopic cavity. The elastic element is sleeved on the outside of the marking pin and abuts between the pressing cap and the end of the connecting rod. The marking pin can extend out of the ruler surface when sliding in the telescopic cavity.

[0017] Preferably, the outer circumferential surface of the pressing cap is provided with anti-slip texture.

[0018] Preferably, the ruler body is provided with two sets of limiting parts, which are spaced apart along the depth direction of the slide groove to form a limiting cavity. The positioning seat is slidably disposed in the limiting cavity, and the marker passes through the two sets of limiting parts.

[0019] Preferably, the multifunctional measuring ruler further includes at least one level bubble level, which is mounted on the ruler body.

[0020] Preferably, the groove and the scale line extend for the same length along the length of the ruler body, and the two ends of the groove are aligned with the zero mark and the maximum range mark of the scale line, respectively.

[0021] Preferably, at least one weight-reducing hole is provided through the ruler body.

[0022] The beneficial effects of this utility model are:

[0023] This invention provides a multifunctional measuring ruler. When precise positioning and marking are required, the positioning seat is slid along the groove to the target scale, and the marker is adjusted to fit the measuring surface to mark points or draw lines. When drawing an arc, the origin component is fixed as the center fulcrum, the distance between the marker component and the origin component is used as the radius, the marker is adjusted to fit the measuring surface, and the ruler is swung to draw the arc. When drawing an arc at a specified angle on a vertical reference plane, the ruler is pressed against the reference plane, and the ruler is swung while observing the angle of the corresponding angle scale ring on the goniometer indicator. When the specified angle is reached, the ruler is stopped, and the arc at the corresponding angle is drawn. By integrating a goniometer and a sliding marker component, the functions of positioning and marking, drawing arcs, and drawing arcs at specified angles on a vertical reference plane are realized on a single tool. This solves the problem of frequently switching between protractors, compasses, and other tools during construction, reduces the carrying burden on operators, and reduces error accumulation.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] like Figures 1-5 As shown, this utility model provides a multifunctional measuring ruler, including a ruler body 1, an origin component 2, a marking component 3, and a goniometer 4. The ruler body 1 has a through groove 10 extending along its thickness direction, and the groove 10 extends along the length direction of the ruler body 1. The ruler body 1 has scale lines 11 parallel to the groove 10. At least a portion of the origin component 2 protrudes from the surface of the ruler body 1. The marking component 3 includes a positioning seat 31 and a marker 32. The positioning seat 31 is disposed in the groove 10 and can slide along the length direction of the groove 10. The marker 32 is adjustablely positioned through the positioning seat 31 along the thickness direction of the ruler body 1. The goniometer 4 is fixedly installed on the ruler body 1 and includes a circular transparent shell 41 and an indicator 42 movably installed in the transparent shell 41. An angle scale ring 12 is circumferentially provided around the transparent shell 41 on the ruler body 1.

[0040] By integrating the protractor 4 with the sliding marking component 3, the system achieves the functions of positioning and marking, drawing arcs, and drawing arcs at specified angles on a vertical reference plane using a single tool. This solves the problem of frequently switching between tools such as protractors and compasses during construction, reduces the carrying burden on operators, and minimizes error accumulation.

[0041] When precise positioning and marking of specific points are required, starting from the origin component 2, the positioning seat 31 is slid along the length of the slide groove 10. The slide groove 10 provides a stable sliding trajectory for the positioning seat 31, avoiding deviation during the sliding process. After the positioning seat 31 slides to the target scale position, the extension length of the marker 32 is adjusted along the thickness direction of the ruler 1 to ensure that the marker 32 can fit the measuring surface. Then, the marker 32 is used to complete the dot or line marking.

[0042] When drawing an arc, first determine the center position of the arc. With the origin component 2 as the center, according to the required radius of the arc, slide the positioning seat 31 of the marking component 3 to move it along the slide groove 10. The distance between the marking component 3 and the origin component 2 is used as the radius. Adjust the marking device 32 of the marking component 3 to fit the measuring surface. Finally, swing the ruler 1 to rotate around the center, and the marking device 32 can draw an arc that meets the accuracy requirements on the measuring surface.

[0043] The indicator 42 includes an indicator liquid, which can be a brightly colored liquid, such as red or green. The colored indicator liquid 32, through color contrast, creates a clear visual distinction between the liquid surface and the inner wall of the transparent housing 41 and the angle scale ring 12, allowing the operator to quickly locate the liquid surface and avoid reading delays or misjudgments caused by visual blur. Furthermore, when the ruler 1 is against a vertical reference plane, the liquid surface of the indicator 32 coincides with the diameter of the angle scale ring 12, facilitating user identification of the scale indicated by the indicator liquid. In other embodiments, the indicator 42 can also be made of a solid material such as a ball bearing or sand grains. The ball bearing or sand grains can roll freely within the transparent housing 41 and indicate the tilt angle of the ruler 1 through gravity.

[0044] When you need to draw an arc at a specified angle on a vertical reference plane, refer to Figure 2 First, place the ruler 1 close to the reference surface and observe the angle indicated by the indicator liquid on the scale ring 12 inside the transparent shell 41. Swing the ruler 1 around the center and observe the change in the angle indicated by the liquid surface of the indicator liquid 32 on the scale ring 12 while rotating. When the rotation angle is the specified angle of the arc, the marker 32 on the sliding marker component 3 can draw an arc of the specified angle on the reference surface.

[0045] In this embodiment, one marker component 3 is provided. In other embodiments, two or more marker components 3 may be provided. The number of marker components 3 is not specifically limited here.

[0046] Specifically, such as Figure 3 and Figure 4 As shown, the ruler body 1 is provided with two sets of limiting parts 13. The two sets of limiting parts 13 are arranged at intervals and opposite each other along the depth direction of the slide groove 10, together forming a limiting cavity 130. The positioning seat 31 is slidably disposed in the limiting cavity 130. The marker 32 is sequentially inserted from top to bottom through the upper limiting part 13, the positioning seat 31, and the lower limiting part 13. The limiting cavity 130 formed by the upper and lower sets of limiting parts 13 provides a stable sliding guide and support for the positioning seat 31, effectively preventing the positioning seat 31 from tilting, shaking, or falling off during the sliding process, thus ensuring the accuracy of length measurement.

[0047] Specifically, such as Figure 3 and Figure 5 As shown, the marker 32 includes a connecting rod 321, a pressing cap 322, a marking pin 323, and an elastic element 324. The connecting rod 321 is screwed to the positioning seat 31 and has a telescopic cavity 3210 extending through it axially. One end of the marking pin 323 is connected to the pressing cap 322, and the other end extends into the telescopic cavity 3210. The elastic element 324 is sleeved on the outside of the marking pin 323 and abuts against the end of the pressing cap 322 and the connecting rod 321. The pressing cap 322 can compress the elastic element 324, causing the marking pin 323 to extend out of the telescopic cavity 3210 and out of the surface of the ruler 1. By pressing down the pressing cap 322, the elastic element 324 can be compressed, driving the marking pin 323 to extend stably and contact the measuring surface for marking or drawing lines. After releasing, the elastic element 324 automatically rebounds, causing the marking pin 323 to retract, effectively avoiding unintentional marking or scratching the surface. The threaded connection structure of the connecting rod 321 is not only easy to install and disassemble, but also allows for flexible adjustment of the position of the connecting rod 211 in the thickness direction of the ruler body 1.

[0048] In this embodiment, the elastic element 324 is a spring.

[0049] More specifically, the outer circumferential surface of the pressing cap 322 is provided with anti-slip texture 3221. The anti-slip texture 3221 can increase friction, reduce marking offset or errors caused by hand slippage, reduce fatigue during long-term continuous operation, and further ensure measurement accuracy.

[0050] More specifically, the 323 marker pegs are made of metal. Metal provides excellent hardness, wear resistance, and rigidity, ensuring that the marker pegs remain sharp on various hard or rough construction surfaces such as concrete, brick, and wood, without easily deforming or wearing down, thus guaranteeing clear and durable markings.

[0051] In this embodiment, the marker 323 is made of steel. In other embodiments, the marker 323 can also be replaced with a crayon tip, an ink pen refill, or other markable object.

[0052] The origin component 2 is slidably mounted on the slide groove 10 and can slide along the length of the slide groove 10. The specific implementation can be consistent with the implementation of the marking component, i.e., the origin component 2 contains the structural components of the marking component 3, including a positioning seat 31 and a marker 32. The marker 32 includes a connecting rod 321, a pressing cap 322, a marking pin 323, and an elastic element 324. The marker 32 is slidably mounted on the slide groove 10 via the positioning seat 31. Furthermore, the ruler 1 is provided with a locking element for locking the position of the origin component 2 on the slide groove 10. The locking element includes a damping layer on the outer peripheral wall of the pressing cap 322. When the pressing cap 322 is pressed, it embeds into the slide groove 10 and abuts against the inner wall of the slide groove 10, thereby limiting the sliding of the positioning seat 31 within the slide groove 10. This prevents the position of the origin component 2 from becoming loose when the user marks or draws arcs, thus avoiding marking errors or skewed arcs, thereby improving the accuracy of marking and drawing.

[0053] Specifically, such as Figure 1 As shown, the multifunctional measuring ruler also includes at least one bubble level 5, which is mounted on the ruler body 1. The bubble level 5 can intuitively and quickly determine whether the ruler body 1 is in an absolutely level state by observing the centering of the bubble, without needing to read the scale values, thus improving the operational efficiency of the basic level calibration of the plate 1.

[0054] In this embodiment, two horizontal bubble meters 5 are provided. One horizontal bubble meter 5 is located at the middle position along the length direction of the ruler 1, and the other horizontal bubble meter 5 and the goniometer 4 are symmetrically arranged along the middle position of the horizontal bubble meter 5 along the length direction of the ruler 1.

[0055] Specifically, the slide groove 10 and the scale line 11 extend for the same length along the length of the ruler body 1, and the two ends of the slide groove 10 are aligned with the zero mark and the maximum range mark of the scale line 11. The consistent extension length of the slide groove 10 and the one-to-one correspondence between the two ends eliminate the problem of mismatch between the sliding range of the positioning seat 31 and the scale range. When the positioning seat 31 is at any position of the slide groove 10, accurate values ​​can be directly read from the scale line 11 without additional conversion or estimation, further reducing positioning errors and ensuring that the marked point and the measured value are completely consistent.

[0056] Specifically, such as Figure 1 As shown, at least one weight-reducing hole 14 is provided through the ruler body 1 along its thickness direction. The weight-reducing hole 14 can effectively reduce the overall weight of the ruler body 1. Especially when the measuring ruler is large or the ruler body 1 is made of metal, it can greatly reduce the fatigue of the operator when holding the ruler, improve the convenience of operation during long-term construction, and ensure the accuracy of functions such as length measurement and arc drawing.

[0057] In this embodiment, two weight-reducing holes 14 are provided on the ruler body 1.

[0058] In other embodiments, a weight-reducing hole 14 may also be provided on the ruler body 1. The number of weight-reducing holes 14 is not specifically limited here.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
