Description

Technical Field

[0001] This utility model relates to the field of drawing ruler technology, specifically a drawing ruler for architectural design. Background Technology

[0002] A drafting ruler is a commonly used drawing tool in architectural design. It is used to draw lines (especially straight lines) and measure lengths. Rulers usually have graduations for measuring lengths, and some rulers have special shapes such as letters or circles in the center to facilitate drawing. In the architectural design process, a large number of straight lines and angles need to be drawn; therefore, the drafting ruler is one of the essential tools in architectural design.

[0003] Patent document CN219446579U discloses a drawing ruler for architectural design, including a first ruler and a second ruler. A screw rod passes through the cavity of the first ruler, and a first connecting rod is installed at the right end of the screw rod. A movable plate is sleeved on the outside of the screw rod, and the second ruler is located above the first ruler. This invention features a second ruler and a first ruler. A horizontal line is drawn on the drawing along the first ruler, and then the second ruler can be moved left or right by rotating the handle to control the screw rod's rotation. This allows the second ruler to be moved without moving the first ruler, enabling the drawing of multiple vertical lines perpendicular to the first ruler. Each vertical line remains parallel and does not skew, reducing drawing errors. Furthermore, because the first ruler is stationary, the second ruler remains vertical, eliminating the need to spend time adjusting its position, thus saving drawing time. However, the existing technology still has shortcomings:

[0004] (1) In the prior art, the second ruler is driven to move by a screw. When the second ruler needs to move a large range, this method takes a lot of time.

[0005] (2) Existing drawing rulers cannot accurately draw angle lines when drawing graphics. Since construction is strictly carried out according to architectural design drawings, a large number of straight lines at different angles need to be drawn during the process of hand-drawing architectural drawings. Existing drawing rulers need to be used with protractors when drawing oblique lines. However, protractors are prone to movement during drawing, which reduces the accuracy of drawing. Moreover, current rulers and protractors are all separate structures. When designing and drawing, multiple rulers need to be prepared at the same time, which is inconvenient to carry and reduces the practicality of drawing rulers.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the above-mentioned defects and provide a drawing ruler for architectural design.

[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a drawing ruler for architectural design, comprising:

[0009] The first ruler, with a protractor at the top;

[0010] The second ruler is set on the protractor;

[0011] A movable structure is located at the bottom of a first ruler. The movable structure includes a groove formed at the top of the first ruler. Limiting rods are fixedly connected to both ends of the inner wall of the groove. A slider is slidably connected within the groove and is slidably connected to the limiting rods. A toothed plate is fixedly connected to the bottom of the slider. A toothed plate is slidably connected to the bottom of the groove. The toothed plate is engaged with the toothed plate. A guide rod is fixedly connected to the bottom of the toothed plate. There are several guide rods of the first type, which are evenly spaced. The bottom end of each guide rod passes through the bottom of the first ruler and is fixedly connected to a connecting plate at its end. A spring is sleeved on the outside of each guide rod and is located inside the groove. A handle is fixedly connected to the bottom of the connecting plate.

[0012] An angle adjustment structure is provided on a protractor. The angle adjustment structure includes a rotating slot at the top of the protractor, with a rotating shaft rotatably inserted at both ends of the inner wall of the rotating slot. One end of the rotating shaft extends to the outside of the protractor and is fixedly connected to a gear at its end. An L-shaped support rod is fixedly connected to the front surface of the protractor, and a pull rod is inserted through the L-shaped support rod. A circular plate is fixedly connected to one end of the pull rod, and a circular groove is formed at the end of the circular plate near the gear. A gear ring is fixedly connected to the inner wall of the circular groove and meshes with the gear. A second spring is sleeved on the outside of the pull rod and is located at the end of the L-shaped support rod near the gear. Two guide rods are fixedly connected to both ends of the circular plate and are inserted through the L-shaped support rod.

[0013] Furthermore, the protractor is fixedly connected to the slider.

[0014] Furthermore, the second ruler is fixedly connected to the outer wall of the rotating shaft.

[0015] Furthermore, the first ruler has a first scale line on its front surface.

[0016] Furthermore, the second ruler has a second scale line on its front surface.

[0017] The advantages of this utility model compared with the prior art are as follows:

[0018] (1) In this utility model, by setting up a movable structure, by pulling the handle outward, the connecting plate drives the toothed plate two to move outward and squeezes the spring one, so that the toothed plate one is disengaged from the toothed plate two. At this time, the second ruler can be moved quickly, so that the second ruler drives the protractor, and then drives the slider to slide left and right on the limit rod. When the second ruler moves into place, the handle is released, and under the elastic action of the spring one, the toothed plate two is re-engaged on the toothed plate one, so that the position of the second ruler can be fixed. There is no need to repeatedly turn the handle, which saves time and effort and is quick and convenient to use.

[0019] (2) In this utility model, by setting the angle adjustment structure, the protractor and the second ruler are combined. When drawing straight lines at different angles, the pull rod can be pulled outward to move the circular plate and squeeze the second spring, so that the gear ring disengages from the gear. At this time, the second ruler can be rotated quickly, so that the second ruler drives the rotating shaft to rotate in the rotating slot on the protractor. When the second ruler rotates to the required angle, the pull rod is released. Under the elastic action of the second spring, the gear ring is re-engaged and connected to the gear, so that the second ruler can be fixed. This ensures that angle lines can be drawn accurately when drawing graphics. It is also easy to carry, use, and operate, which greatly improves the practicality of the drawing ruler.

[0027] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] like Figures 1 to 6 As shown, this embodiment proposes a drawing ruler for architectural design, including a first ruler 1, a protractor 2 on the top of the first ruler 1, and a second ruler 3 on the protractor 2. By combining the protractor 2 and the second ruler 3, it is not necessary to prepare multiple rulers at the same time when drawing designs, and it is easy to carry.

[0030] The bottom of the first ruler 1 is provided with a movable structure 4, which includes a groove 41 formed at the top of the first ruler 1. Limiting rods 42 are fixedly connected to both ends of the inner wall of the groove 41. There are two limiting rods 42. A slider 43 is slidably connected inside the groove 41 and is slidably connected to the limiting rods 42. The protractor 2 is fixedly connected to the slider 43. A toothed plate 44 is fixedly connected to the bottom of the slider 43. A second toothed plate 45 is slidably connected to the bottom of the groove 41. The first toothed plate 44 is engaged with the second toothed plate 45 to facilitate the limiting and fixing of the slider 43's position. A guide is fixedly connected to the bottom of the second toothed plate 45. There are several guide rods 46, which are evenly spaced. The bottom end of the guide rod 46 is inserted into the bottom of the first ruler 1 and the end is fixedly connected to the connecting plate 47. A spring 48 is sleeved on the outside of the guide rod 46 and is located inside the groove 41. A handle 49 is fixedly connected to the bottom of the connecting plate 47. By pulling the handle 49 outward, the connecting plate 47 drives the toothed plate 45 to move outward and squeezes the spring 48, so that the toothed plate 44 disengages from the toothed plate 45. At this time, the second ruler 3 can be moved quickly without repeatedly turning the handle to drive the screw to rotate for adjustment, which saves time and effort.

[0031] The protractor 2 is equipped with an angle adjustment structure 5, which includes a rotating slot 51 at the top of the protractor 2. A rotating shaft 52 is rotatably inserted into both ends of the inner wall of the rotating slot 51. A second ruler 3 is fixedly connected to the outer wall of the rotating shaft 52. One end of the rotating shaft 52 extends to the outside of the protractor 2 and is fixedly connected to a gear 53. An L-shaped support rod 54 is fixedly connected to the front surface of the protractor 2. A pull rod 55 passes through the L-shaped support rod 54. A circular plate 56 is fixedly connected to one end of the pull rod 55. A circular groove is formed at the end of the circular plate 56 near the gear 53. A gear ring 57 is fixedly connected to the inner wall of the circular groove. The gear 53 is meshed with the pull rod 55, and a second spring 58 is sleeved on the outside of the pull rod 55. The second spring 58 is located at one end of the L-shaped support rod 54 near the gear 53. The two ends of the circular plate 56 are fixedly connected to the guide rods 59, which are inserted into the L-shaped support rod 54. By pulling the pull rod 55 outward, the circular plate 56 is moved and the second spring 58 is squeezed, so that the gear ring 57 disengages from the gear 53. At this time, the second ruler 3 can be quickly rotated, so that the second ruler 3 drives the rotating shaft 52 to rotate to the required angle in the rotating slot 51 on the protractor 2. This makes it convenient to draw straight lines at different angles, and is easy to use and operate.

[0032] The first ruler 1 has a first scale line 6 on its front surface, and the second ruler 3 has a second scale line 7 on its front surface. By placing the first ruler 1 on the drawing paper and adjusting the angle between the first ruler 1 and the second ruler 3, as well as the position of the second ruler 3, it is easy to draw multiple straight lines with different angles, which helps to improve the accuracy of the drawing. Secondly, it eliminates the need to move the entire drawing ruler repeatedly, which helps to shorten the drawing time.

[0033] In practical implementation, the first ruler 1 is placed on the drawing. Then, according to actual needs, the handle 49 is pulled outward, causing the connecting plate 47 to move the toothed plate 45 outward and compress the spring 48, disengaging the toothed plate 44 from the toothed plate 45. At this point, the second ruler 3 can be quickly moved, causing the second ruler 3 to move the protractor 2, which in turn causes the slider 43 to slide left and right on the limiting rod 42. When the second ruler 3 is in position, the handle 49 is released. Under the elastic action of the spring 48, the toothed plate 45 re-engages with the toothed plate 44, thus fixing the position of the second ruler 3. Then, when it is necessary to draw... When drawing straight lines at the same angle, the pull rod 55 can be pulled outward to move the circular plate 56 and compress the second spring 58, causing the gear ring 57 to disengage from the gear 53. At this time, the second ruler 3 can be quickly rotated, causing the second ruler 3 to drive the rotating shaft 52 to rotate within the rotating slot 51 on the protractor 2. After the second ruler 3 has rotated to the required angle, the pull rod 55 can be released. Under the elastic action of the second spring 58, the gear ring 57 will re-engage with the gear 53, thus fixing the second ruler 3. This ensures that angle lines can be drawn accurately when drawing graphics. It is also easy to carry, use, and operate, greatly improving the practicality of the drawing ruler.
