Description

Technical Field

[0001] The utility model relates to the technical field of drawing tools, in particular to a drawing tool. Background Art

[0002] Currently, in the application of geometric drawing tools, especially in engineering drawing and school teaching practice, a variety of drawing and measuring tools are often required, such as set squares, protractors, rulers and compasses.

[0003] Regarding the above-mentioned related technologies, the inventor believes that the following defects exist: the existing drawing tools are mostly a set of drawing tools consisting of a ruler, a triangle and a protractor. In this process, when the staff is drawing, the drawing tools need to be constantly replaced, thereby reducing the staff's work efficiency, because each tool is independent, which easily causes the loss of a single tool. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a drawing tool for drawing.

[0005] The above technical purpose of the present utility model is achieved through the following technical solutions: a drawing tool, comprising an angle plate with an arc-shaped cross-section, a plurality of angle lines on the side wall of the angle plate, an arc groove penetrating the side wall of the angle plate, a ruler installed at one end of the straight edge of the angle plate, a plurality of scale lines on the side wall of the ruler, a rotating shaft rotatably provided on the side wall of the angle plate, a rotating rod sleeved on the side wall of the rotating shaft, and the axis of the rotating shaft and the degree angle lines are perpendicular to each other.

[0006] By adopting the above technical solution, when a worker needs to use a drafting tool to draw a map, the worker can use a ruler to draw straight lines and use the angle plate to measure angles. Furthermore, when the worker needs to draw an angle, the worker rotates the rotating rod to the corresponding angle line. At this point, the worker simply draws a straight line along the rotating rod. This process can complete the work of a single set of drafting tools, eliminating the need to frequently change drafting tools during the drawing process, thereby improving worker efficiency.

[0007] Furthermore, a slide groove is provided on the upper surface of the ruler, a slider is slidably provided in the slide groove, a through groove is provided on the upper surface of the slider, a groove is provided on the side wall of the ruler, and the axis of the groove is perpendicular to the scale line.

[0008] By adopting this technical solution, when a worker needs to draw a circle, they slide the slider according to the radius of the circle until it reaches the appropriate scale line. At this point, the worker inserts the pen through the slot, with the axis of the groove as the center of the circle, into contact with the paper. The worker then rotates the pen around the groove to draw the circle, thus simplifying the process.

[0009] Furthermore, a tapered block is fixedly provided on the side wall of the ruler away from the groove, and the axis of the tapered block coincides with the axis of the groove.

[0010] By adopting the above technical solution, when the worker draws a circle, the conical block is pressed tightly against the paper. During this process, the conical block reduces the probability of deviation during the circle drawing process.

[0011] Furthermore, a limiting groove is provided on the inner wall of the slide groove, a limiting block is slidably arranged in the limiting groove, and the limiting block and the slide block are fixed to each other.

[0012] By adopting the above technical solution, when the staff slides the slider, the limit block slides synchronously with the slider under the action of the slider. During this process, the side wall of the limit block abuts against the inner wall of the limit groove, thereby reducing the probability of the slider and the slide groove separating from each other, thereby improving the stability of the device.

[0013] Furthermore, a rubber pad is fixedly provided on the side wall of the limiting block away from the sliding block, and the side wall of the rubber pad away from the limiting block abuts against the inner wall of the limiting groove.

[0014] By adopting the above technical solution, the rubber has good elasticity, and the rubber pad made of rubber increases the upper limit of the maximum static friction between the limit block and the limit groove, thereby reducing the probability of the slider sliding when the staff draws a circle, thereby improving the stability of the device.

[0015] Furthermore, both ends of the rotating rod are provided with rounded corners.

[0016] By adopting the above technical solution, both ends of the rotating rod are provided with rounded corners, which reduces the probability of the rotating rod causing injuries to workers due to sharp corners.

[0017] Furthermore, the angle plate is made of plastic material, and the ruler is made of plastic material.

[0018] By adopting the above technical solution, the angle plate and ruler made of plastic material not only reduce the weight of the device body but also the plastic has good toughness, thereby reducing the probability of damage to the angle plate and ruler.

[0019] Furthermore, a pointer is fixedly provided on the side wall of the slider.

[0020] By adopting the above technical solution, the pointer improves the accuracy of workers when drawing circles.

[0021] Furthermore, a fixing knob is threadedly provided on the side wall of the slider, and the fixing knob extends into the through slot.

[0022] By adopting the above technical solution, when the staff installs the pen in the through slot, the staff needs to fix the pen by turning the fixing knob, thereby reducing the probability of the pen shaking during drawing, and thus reducing the probability of the pen tip offset.

[0023] In summary, the present invention has the following beneficial effects:

[0024] 1. In this application, when a worker needs to use a drawing tool to draw a map, the worker can use a ruler to draw a straight line and use an angle plate to measure an angle. In addition, when the worker needs to draw an angle, the worker needs to rotate the rotating rod to rotate the rotating rod to the corresponding angle line. At this time, the worker can draw a straight line along the rotating rod. In this process, the work of a set of drawing tools can be completed, eliminating the need to frequently change drawing tools during the drawing process, thereby improving the worker's work efficiency;

[0025] 2. In this application, when the staff needs to draw a circle, they need to slide the slider according to the radius of the circle, and then slide the slider to the appropriate scale line. At this time, the staff uses the axis of the groove as the center of the circle, passes the pen through the groove and contacts the paper. Then, the staff rotates the pen with the groove as the center of the circle to draw the circle, thereby reducing the difficulty of drawing the circle for the staff, thereby reducing the difficulty of the staff's work;

[0026] 3. In this application, when the staff draws a circle, the conical block is pressed against the paper. During this process, the conical block reduces the probability of deviation during the circle drawing process. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0032] like Figure 1-3 As shown, an embodiment of the present application discloses a drawing tool, comprising an angle plate 1, a ruler 11, a rotating shaft 12, a rotating rod 13, a slider 3, a tapered block 4, a limit block 5 and a rubber pad 6. The cross section of the angle plate 1 is arc-shaped, and there are multiple angle lines on the side wall of the angle plate 1. An arc groove 2 is provided through the side wall of the angle plate 1. The ruler 11 is installed at one end of the straight edge of the angle plate 1, and there are multiple scale lines on the side wall of the ruler 11. The rotating shaft 12 is a round rod-shaped structure with a horizontal axis. The rotating shaft 12 is rotatably set on the side wall of the angle plate 1. The rotating rod 13 is a rectangular rod-shaped structure. The rotating rod 13 is sleeved on the side wall of the rotating shaft 12, and the axis of the rotating shaft 12 is perpendicular to the angle line.

[0033] When using a drafting tool, a worker can draw a straight line with a ruler 11 and measure an angle with the angle plate 1. Furthermore, when drawing an angle, the worker rotates the rotating rod 13 until it reaches the corresponding angle. At this point, the worker simply draws a straight line along the rotating rod 13. This process allows the work of a single set of drafting tools to be completed, eliminating the need to frequently change drafting tools during the drawing process, thereby improving work efficiency.

[0034] A slide groove 21 is provided on the upper surface of the ruler 11. The slider 3 is a rectangular block structure. The slider 3 is slidably arranged in the slide groove 21. A through groove 22 is provided on the upper surface of the slider 3. A groove 23 is provided on the side wall of the ruler 11, and the axis of the groove 23 is perpendicular to the scale line.

[0035] To draw a circle, the operator slides slider 3 according to the radius of the circle until it reaches the appropriate scale line. At this point, the operator inserts the pen through slot 22, with the axis of groove 23 as the center, into contact with the paper. The operator then rotates the pen around groove 23 to draw the circle, simplifying the process.

[0036] The conical block 4 is fixedly arranged on the side wall of the ruler 11 away from the groove 23 , and the axis of the conical block 4 coincides with the axis of the groove 23 .

[0037] When the worker draws a circle, the conical block 4 is pressed against the paper. During this process, the conical block 4 reduces the probability of deviation during the circle drawing process.

[0038] A limiting groove 24 is provided on the inner wall of the slide groove 21 . The limiting block 5 is a rectangular block structure. The limiting block 5 is slidably disposed in the limiting groove 24 , and the limiting block 5 and the slider 3 are fixed to each other.

[0039] When the staff slides the slider 3, the limit block 5 slides synchronously with the slider 3 under the action of the slider 3. During this process, the side wall of the limit block 5 abuts against the inner wall of the limit groove 24, thereby reducing the probability of the slider 3 and the slide groove 21 separating from each other, thereby improving the stability of the device.

[0040] The rubber pad 6 is fixedly arranged on the side wall of the limiting block 5 away from the sliding block 3 , and the side wall of the rubber pad 6 away from the limiting block 5 abuts against the inner wall of the limiting groove 24 .

[0041] Rubber has good elasticity. The rubber pad 6 made of rubber increases the upper limit of the maximum static friction between the limit block 5 and the limit groove 24, thereby reducing the probability of the slider 3 sliding when the staff draws a circle, thereby improving the stability of the device.

[0042] In order to reduce the probability of the rotating rod 13 corners being too sharp and causing harm to the staff, both ends of the rotating rod 13 are provided with rounded corners 7. Both ends of the rotating rod 13 are provided with rounded corners 7 to reduce the probability of the rotating rod 13 corners being too sharp and causing harm to the staff.

[0043] To reduce the probability of damage to the angle plate 1 and the ruler 11, the angle plate 1 is made of plastic, and the ruler 11 is made of plastic. Plastic not only reduces the weight of the device, but also provides good toughness, thereby reducing the probability of damage to the angle plate 1 and the ruler 11.

[0044] In order to improve the accuracy of the staff when drawing a circle, a pointer 8 is fixedly provided on the side wall of the slider 3. The pointer 8 improves the accuracy of the staff when drawing a circle.

[0045] In order to reduce the probability of the pen tip shifting, a fixing knob 9 is threadedly provided on the side wall of the slider 3, and the fixing knob 9 extends into the through slot 22. When the staff installs the pen in the through slot 22, the staff needs to fix the pen by turning the fixing knob 9, thereby reducing the probability of the pen shaking during drawing and thus reducing the probability of the pen tip shifting.

[0046] The working principle of a drawing tool in this embodiment is as follows: when a worker uses the drawing tool to draw a line, they draw a straight line with a ruler 11 and measure an angle with an angle plate 1. Furthermore, when the worker needs to draw an angle, they rotate a rotating rod 13 to the corresponding angle line. At this point, the worker simply draws a straight line along the rotating rod 13. This process completes the work of a single drawing tool, eliminating the need to frequently change drawing tools during the drawing process, thereby improving worker efficiency.

[0047] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
