Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical drawing technology, specifically a measuring tool for drawing design. Background Technology
[0002] In drawing design, the selection and use of measuring tools directly determines the accuracy of the design. Commonly used measuring tools include vernier calipers, micrometers, micrometers, steel rulers, squares, and spirit levels. When selecting measuring tools, priority should be given to their measurement accuracy and applicability to ensure that they can meet the design requirements. Vehicle design often uses drawings for surveying. The surveying work is extensive and requires high accuracy. In addition, the drawings need to be transferred and used in different environments, which makes the drawings susceptible to environmental influences, causing unevenness on the surface and affecting the surveying accuracy.
[0003] For example, a measuring tool for drawing design described in patent document CN214065880U uses a long groove on the measuring tool body to fix a movable box in the long groove with a pressure rod. The user can move the movable box to any position with a pen tip, making it convenient for the user to draw a straight line of a fixed length using the long groove. A rubber pad is set at the second end of the pressure rod to increase the friction between the second end of the pressure rod and the long groove, making the movable box more stable in the long groove. However, this measuring tool for drawing design cannot check whether the drawing is flat, which can easily affect the measurement results. It is also inconvenient to measure circular patterns, requiring additional drawing steps, and its applicability is limited.
[0004] Based on this, a measuring tool for drawing design is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0026] In one embodiment, such as Figures 1-3 As shown, a measuring tool for drawing design includes a ruler 101 with an opening 102 and markings 103 on its surface. The markings 103 have a pointer 308 for displaying measurement results. The measuring position of the ruler 101 is equipped with a checking mechanism for inspecting the flatness of the drawing. The ruler 101 has an adjustment structure for adjusting the pointer 308. By aligning the ruler 101 with the drawing and adjusting the pointer 308, the measurement result is obtained through the markings 103, avoiding errors in the observation results caused by light refraction.
[0027] In one embodiment, such as Figure 2 As shown, the inspection mechanism includes a fixed base 201, which is fixedly connected to the surface of the measuring scale 101. A first laser 202 is provided at the front end of the fixed base 201, and a second laser 203 is provided on the side of the fixed base 201. A measuring device for directly measuring the diameter of a circular pattern is provided on the side of the fixed base 201. By turning on the second laser 203, the second laser 203 emits a ray that is parallel to the drawing. By observing whether the ray intersects with the drawing, it is determined whether the drawing is flat, thus avoiding errors in the measurement results due to unevenness of the drawing surface.
[0028] In one embodiment, such as Figure 2 and Figure 3As shown, the measuring device includes an adjustment block 206, which is located on the side of the fixed base 201. A third laser 204 is provided on the side of the adjustment block 206, and a fourth laser 205 is provided at the front end of the adjustment block 206. By turning on the third laser 204 and the second laser 203, the intersection of the two rays is observed to determine whether the second laser 203 and the third laser 204 are parallel to the tabletop, and the measurement results are further refined. By adjusting the measuring end of the ruler 101 to be tangent to the circular pattern through the rays of the first laser 202 and the fourth laser 205, the size of the circular pattern can be directly obtained, thus increasing the applicability of the measurement.
[0029] In one embodiment, such as Figure 3 and Figure 4 As shown, the adjustment structure includes a sliding block 307, which is slidably connected to a measuring scale 101. One end of the sliding block 307 is fixedly connected to an adjustment block 206, and the other end of the sliding block 307 is fixedly connected to a pointer 308. The upper end of the sliding block 307 is fixedly connected to a transmission block 306, and the upper end of the transmission block 306 is fixedly connected to a drive component that drives the transmission block 306 to move. The sliding of the sliding block 307 within the measuring scale 101 provides conditions for adjusting the positions of the adjustment block 206 and the pointer 308.
[0030] In one embodiment, such as Figure 3 and Figure 4 As shown, the drive assembly includes a rack 305, which is fixedly connected to the upper end of the transmission block 306. A gear 303 is provided on the side of the rack 305, and the gear 303 meshes with the rack 305. The upper end of the gear 303 is rotatably connected to the inner wall of the measuring scale 101, and the lower end of the gear 303 is fixedly connected to a worm gear 304. A worm 302 is provided on the side of the worm gear 304, and a rotating block 301 is fixedly connected to the side of the worm 302. By rotating the rotating block 301, the rotating block 301 drives the worm 302 to rotate, the worm 302 drives the worm gear 304 to rotate, the worm gear 304 drives the gear 303 to rotate, the gear 303 drives the rack 305 to move, the rack 305 drives the transmission block 306 to move, and the transmission block 306 drives the sliding block 307 to slide within the measuring scale 101, providing conditions for the movement of the transmission block 306.
[0031] The above embodiment discloses a measuring tool for drawing design. Before measurement, the intersection of two rays is observed by turning on laser 204 (number three) and laser 203 to determine if laser 203 and laser 204 are parallel to the table. The flatness of the drawing is determined by observing whether the rays intersect with the drawing. Rotating the rotating block 301 causes the worm gear 302 to rotate, which in turn causes the worm wheel 304 to rotate. The worm wheel 304 then causes the gear 303 to rotate, which in turn causes the gear 303 to rotate. When rack 305 moves, it drives transmission block 306 to move. Transmission block 306 drives sliding block 307 to slide within measuring scale 101. Adjusting the positions of adjusting block 206 and pointer 308, the measurement result is obtained through scale mark 103 after adjustment, avoiding errors in the observation result caused by light refraction. When it is necessary to measure a circular pattern, the rays of laser 1 202 and laser 4 205 are tangent to the circular pattern. The measuring end of measuring scale 101 is adjusted to be tangent to the circular pattern, and the size of the circular pattern is directly obtained.
[0032] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
