[0002] Mechanical design is a comprehensive field encompassing art, science, and technology. It aims to conceive, analyze, and calculate a machine's operating principles, structure, motion, force and energy transmission, component materials, dimensions, and lubrication methods, based on operational requirements. This process translates into detailed descriptions that serve as a basis for manufacturing. Mechanical design involves measuring drawings or components.

[0003] Measuring devices used in mechanical design in the prior art generally have relatively simple functions. "A Multifunctional Measuring Device for Mechanical Design, Publication No. 'CN218380695U'," discloses that by rotating a first measuring ruler, measurement can be achieved through the desired length, thereby achieving an extended measurement operation for the desired length of the object being measured, effectively reducing the limitations caused by the short distance between the measuring rulers during the measurement process. However, the above-mentioned device does not ensure that the two measuring rulers are on the same horizontal line during the length extension. If there is an angle between the two, the result obtained is inaccurate. Moreover, due to the size of the measuring plate and the rotating shaft, the measured angle is also not precise. The device also cannot conveniently draw a circle based on the radius, and its functions are relatively simple. Therefore, to solve the above-mentioned problems, the present application provides a multifunctional measuring device for mechanical design. Utility Model Content

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-5 This application is described in further detail.

[0024] Example 1

[0025] Reference Figure 1-5 A multifunctional measuring device for mechanical design includes a first measuring plate 1, one end of the first measuring plate 1 is fixedly connected to a rotating tube 7, the outer wall of the rotating tube 7 is rotatably connected to the second measuring plate 2, the second measuring plate 2 is located above the first measuring plate 1 and the two have the same size, a moving groove 4 is provided through the side wall of the first measuring plate 1, a moving block 6 is slidably provided in the moving groove 4, the moving block 6 is fixedly connected to a limiting plate 5, the limiting plate 5 is in contact with the side wall of the first measuring plate 1, the limiting plate 5 slides and is in contact with the side wall of the second measuring plate 2, the first measuring plate 1 and the second measuring plate 2 are aligned, and the sliding limiting plate 5, when the limiting plate 5 slides to one end close to the rotating tube 7, pushes the second measuring plate 2 and the first measuring plate 1 to be aligned, thereby reducing the measurement error.

[0026] The upper walls of both the first and second measuring plates 1, 2 are marked with scales. The first and second measuring plates 1, 2 are aligned, with the end of the scale on the first measuring plate 1 corresponding to the start of the scale on the second measuring plate 2. If a complete measurement using the first measuring plate 1 is difficult, the length of the first measuring plate 1 can be directly added to the scale on the second measuring plate 2 to obtain an accurate value. A sliding groove 9 is provided through both the first and second measuring plates 1, 2. The sliding groove 9 cooperates with the rotating tube 7, with the center of the sliding groove 9 aligned with the center of the circle of the rotating tube 7. A sliding block 3 is slidably mounted within each sliding groove 9. The sliding of the sliding block 3 within the sliding groove 9 is achieved through the cooperation of sliding grooves provided on the front and rear walls of the sliding groove 9 and a slider fixedly connected to the sliding block 3, as is known in the art. An indicator plate 13 is fixed above each sliding block 3. If the distance below is insufficient, the device can be placed above the point to be measured, and measurement can be performed using the cooperation of the sliding block 3 and the indicator plate 13.

[0027] An alignment plate 10 is located at the bottom of the rotating tube 7, located at its center. It is fixedly connected to the rotating tube 7 via four fixing posts. This plate is used to align the center of a circle when measuring angles and drawing circles, improving the accuracy of the device. A scale for angle measurement is provided on the top wall of the rotating tube 7. An indicator bar 8 is fixedly connected to the top wall of the second measuring plate 2. This indicator bar 8 is located in the middle of the second measuring plate 2 and aligns with the scale on the top wall of the rotating tube 7. When the second measuring plate 2 rotates, the indicator bar 8 rotates accordingly and aligns with the scale on the top wall of the rotating tube 7.

[0028] A first alignment bar 11 is fixedly connected to the inner wall of the sliding groove 9 of the first measuring plate 1, and a second alignment bar 12 is fixedly connected to the inner wall of the sliding groove 9 of the second measuring plate 2. The second alignment bar 12 is arranged away from the rotating tube 7 and its lower end is flush with the lower end of the first measuring plate 1. The first alignment bar 11 and the second alignment bar 12 are both located in the center of the sliding groove 9. The first alignment bar 11 and the second alignment bar 12 are aligned with the line to be measured during measurement, thereby improving the measurement accuracy and reducing the error caused by the equipment size.

[0029] The lower wall of the sliding block 3 of the second measurement plate 2 is fixedly connected to a fixed box 14. A screw 15 is rotatably mounted on the upper wall of the fixed box 14. A sleeve 16 is threadedly connected to the lower end of the screw 15. The sleeve 16 extends through the lower wall of the fixed box 14 and is snap-fitted to the lower end of the sleeve 16, allowing replacement of the brush. A gear 17 is coaxially fixedly mounted on the screw 15. A rack 18 is slidably mounted on the side wall of the fixed box 14. The groove in the fixed box 14 for the rack 18 to slide inward is provided with a limiter. When the rack 18 slides to its innermost position, the sleeve 16 reaches its highest position. When the rack 18 slides to its outermost position, the sleeve 16 reaches its lowest position and remains engaged with the screw 15. The lowest position of the sleeve 16 is lower than the lower wall of the first measurement plate 1, ensuring that the brush can contact the surface to be drawn. The rack 18 meshes with the gear 17 and extends through the fixed box 14 and is slidably connected thereto.

[0030] In actual use, first slide the limit plate 5 until its side wall is in contact with the side wall of the second measuring plate 2. At this time, the first measuring plate 1 and the second measuring plate 2 are flush, and the length measurement can be performed. The device makes the first measuring plate 1 and the second measuring plate 2 flush during measurement, thereby improving the measurement accuracy.

[0031] Align the connection of the angle to be measured with the alignment piece 10, and align the line to be measured with the first alignment bar 11. Rotate the second measuring plate 2 so that the second alignment bar 12 is aligned with the other line to be measured. The angle can be read according to the scale on the indicator bar 8 and the rotating tube 7. The arrangement of the first alignment bar 11, the second alignment bar 12 and the alignment piece 10 reduces the error caused by the size of the device itself and improves the measurement accuracy.

[0032] When drawing a circle, align the line segment with the first alignment bar 11, align the alignment piece 10 with the center of the circle at one end of the line segment, slide the indicator piece 13 on the second measuring plate 2 to the radius position, push the rack 18 so that the paintbrush touches the paper, and rotate the second measuring plate 2 to draw the circle. After drawing most of the circle, hold the second measuring plate 2 to ensure that the center of the circle does not move, rotate the first measuring plate 1 and rotate the rotating tube 7; after changing the position of the first measuring plate 1, fix the first measuring plate 1 again and rotate the second measuring plate 2 to complete the subsequent circle drawing.
