[0028] The following describes an embodiment of the present invention based on its overall structure. Example 1
[0029] An auxiliary drawing tool for architectural engineering design, such as Figures 1-4As shown, it includes a magnetic plate 1, two sides of the magnetic plate 1 are slidably connected to sliding blocks 2, one side of the sliding block 2 is rotatably connected to a connecting rod 12, the top of the connecting rod 12 is rotatably connected to a cross bar 3, and the back of the cross bar 3 is provided with a fixing mechanism 4, the fixing mechanism 4 includes a mounting groove 401, the interior of the mounting groove 401 is fixedly connected to a first electrical soft iron 402 and a second electrical soft iron 403, a bronze sheet 405 is fixedly connected between the first electrical soft iron 402 and the second electrical soft iron 403, and a bronze sheet 405 is fixedly connected between the first electrical soft iron 402 and the second electrical soft iron 403. A permanent magnet 404 is arranged between the magnetic plate 1 and the sliding block 2, and the permanent magnet 404 is rotatably connected to the mounting groove 401. Through the combination of the permanent magnet 404, the first electrical soft iron 402 and the second electrical soft iron 403 in the fixing mechanism 4, the cross bar 3 is firmly fixed when needed and easily slides when not needed, which greatly improves the convenience and accuracy of architectural engineering design drawings. At the same time, the sliding connection between the magnetic plate 1 and the sliding block 2, and the rotational connection between the connecting rod 12 and the cross bar 3, realize the flexible adjustment and stable support of the ruler on the magnetic plate 1.
[0030] See Figure 1 、 Figure 2 and Figure 3 The back of the cross bar 3 is fixedly connected to the mounting plate 5 by bolts, and the mounting plate 5 is rotatably connected to the knob 6. The knob 6 is fixedly connected to the permanent magnet 404. The mounting plate 5 fixedly connected to the back of the cross bar 3 by bolts provides a stable support for the knob 6. At the same time, the fixed connection between the knob 6 and the permanent magnet 404 allows the user to control the rotation of the permanent magnet 404 by simply rotating the knob 6, thereby achieving the fixation and release of the cross bar 3 on the magnetic plate 1, and the operation is simple and quick.
[0031] See Figure 1 、 Figure 2 and Figure 3 , multiple fixing mechanisms 4 and knobs 6 are provided, and the multiple fixing mechanisms 4 and knobs 6 are arranged linearly and equidistantly. The multiple fixing mechanisms 4 enhance the fixed point position of the cross bar 3 on the magnetic plate 1, improve the stability of the fixation, and make the drawing tool more reliable during use. At the same time, the multiple knobs 6 are arranged linearly and equidistantly, so that the fixing mechanisms 4 in different positions can be transformed at the same time, which improves the adjustment speed and thus improves the convenience of the drawing tool.
[0032] See Figure 1 、 Figure 2 and Figure 3One end of each knob 6 is rotatably connected to a pressure plate 7, and a spring 8 for resetting is provided between the pressure plate 7 and the cross bar 3. The pressure plate 7 rotatably connected at one end of the knob 6 provides the user with an intuitive and easy-to-operate interface. The cross bar 3 can be fixed and released by simply pressing. At the same time, the reset spring 8 provided between the pressure plate 7 and the cross bar 3 ensures that the pressure plate 7 can automatically reset when not subjected to external force, thereby realizing automatic locking operation and improving the user experience.
[0033] See Figure 4 A slot 9 is provided at the front end of the cross bar 3, and a rubber fixing block 10 is fixedly connected to the inside of the slot 9. The slot 9 provided at the front end of the cross bar 3 provides a stable insertion position for the ruler, ensuring that the ruler will not slide or fall off during use. At the same time, the rubber fixing block 10 fixedly connected to the inside of the slot 9 not only enhances the friction between the ruler and the slot 9, but also improves the fixing stability of the ruler, prevents the ruler from falling, and extends the service life of the drawing tool.
[0034] The implementation principle of the present invention is as follows: first, a ruler is inserted into the card slot 9, and the rubber fixing block 10 plays a fixing role. When sliding is required, the pressure plate 7 is first pressed, and the pressure plate 7 drives the permanent magnet 404 to rotate through the knob 6. When the two poles of the permanent magnet 404 are in the horizontal direction and the middle of NS is facing the first electrical soft iron 402 and the second electrical soft iron 403 (the middle of the long strip permanent magnet 404 has only very small magnetism and can be ignored), the first electrical soft iron Iron 402 and the second electrical soft iron 403 are not magnetized. Therefore, at this time, there is almost no magnetic force at the bottom of the first electrical soft iron 402 and the second electrical soft iron 403, allowing the cross bar 3 to slide smoothly. When the pressure plate 7 is released, the spring 8 pushes the pressure plate 7 to return to its original position, and the pressure plate 7 drives the permanent magnet 404 to rotate. At this time, when the two poles (N or S) of the permanent magnet 404 are in the vertical direction, that is, when the N or S pole of the magnet is facing the first electrical soft iron 402 and the second electrical soft iron 403, the first electrical soft iron 402 and the second electrical soft iron 403 are magnetized. The bottom of the first electrical soft iron 402 and the second electrical soft iron 403 have strong magnetism, which attracts the magnetic plate 1 and fixes the cross bar 3. Example 2
[0035] See Figure 4 A metal strip 11 is adsorbed on the surface of the magnetic plate 1, and a plurality of metal strips 11 are provided. The metal strips 11 adsorbed on the surface of the magnetic plate 1 provide additional pressing force for the paper during the drawing process, effectively preventing the paper from sliding or shifting during drawing. At the same time, the provision of multiple metal strips 11 makes the pressing force more uniform and adjustable. Users can adjust the number and position of the metal strips 11 as needed to adapt to papers of different sizes, thereby improving the applicability and flexibility of the drawing tool.
[0036] The implementation principle of the present invention is as follows: first, the metal pressure strip 11 can be used to press the paper to prevent it from sliding during drawing.
