Description

Technical Field

[0001] This utility model belongs to the field of teaching equipment technology, and in particular relates to a tool for drawing linear equations. Background Technology

[0002] In vocational school mathematics teaching, the equation of a straight line is a fundamental part of analytic geometry, involving core concepts such as slope, intercept, and fixed point. Visually presenting the geometric meaning of the equation of a straight line through drawing is an important teaching method to help students understand and master the relevant knowledge.

[0003] Currently, the tools used in vocational school mathematics teaching to draw straight line equations are mostly traditional rulers and set squares. In actual use, when drawing a straight line with a specific slope or passing through a specific point, these tools require multiple measurements, markings, and adjustments of the tool angles. The operation is cumbersome and the accuracy is low. Human error can easily lead to a large deviation between the drawn line and the theoretical equation. Summary of the Invention

[0004] In response to the above situation, in order to overcome the shortcomings of the low accuracy of existing technologies.

[0005] The technical solution adopted by this utility model is as follows: A linear equation drawing tool includes a base frame and a drawing component. The base frame is arranged in a cross shape. The drawing component is located at the upper end of the base frame. The drawing component includes a slider one, a support one, a slider two, and a support two. A sliding groove one is opened through the base frame. The slider one is symmetrically slidably arranged inside the sliding groove one. The support one is fixedly connected to the upper end of the slider one. A sliding groove two is opened on the support one. The slider two is slidably arranged inside the sliding groove two. The two ends of the support two are respectively fixedly connected to two slider two. A sliding groove three is opened through the support two. An adjusting rod is fixedly connected to the upper end of the slider two and passes through the sliding groove three. A fixing bolt is threadedly connected to the adjusting rod.

[0006] Furthermore, the end of the base frame is also provided with a fixing component, the fixing component includes an adjusting column, the end of the base frame is provided with a fixing hole, the side of the adjusting column is threaded to the inside of the fixing hole, and a permanent magnet is fixedly connected to the lower end of the adjusting column.

[0007] Furthermore, the cross-sections of slider one and slider two are convex, and the inner sides of slide groove one and slide groove two are adapted to slider one and slider two.

[0008] Furthermore, the lower end of the fixing bolt is provided with an anti-slip groove, and the lower end of the fixing bolt is in contact with the upper end of the bracket.

[0009] Furthermore, a scale one is provided on the upper end of the base frame, and a scale two is provided on the support one.

[0010] The beneficial effects of this utility model after adopting the above structure are as follows:

[0011] This invention provides a stable reference through a cross-shaped base frame. Combined with the sliding of slider one and slider two within slide groove one and slide groove two, and the locking function of the adjusting rod and the fixing bolt, it can locate the slope, intercept, or fixed point of a straight line, greatly reducing human operation errors and ensuring that the drawing result is highly consistent with the geometric meaning of the straight line equation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all 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 protection scope of the present utility model.

[0021] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0022] like Figures 1-3 As shown, a linear equation drawing tool includes a base frame 10 and a drawing component 20. The base frame 10 is arranged in a cross shape, and the drawing component 20 is located on the upper end of the base frame 10. The drawing component 20 includes a slider 21, a support 22, a slider 24, and a support 26. A groove 11 is provided through the base frame 10. There are two supports 22. The slider 21 is located at the bottom of the support 22, and the support 22 is slidably positioned in the groove 11 via the slider 21. A groove 23 is provided on the support 22. The bottom of the support 26 has symmetrically arranged sliders 24, and the support 26 is slidably positioned in the grooves 23 of the two supports 22 via the sliders 24. A groove 35 is provided through the support 26. An adjusting rod 27 is fixedly connected to the upper end of the slider 24 and passes through the groove 35. A fixing bolt 28 is threaded onto the adjusting rod 27.

[0023] This utility model uses a cross-shaped base frame 10 to provide a stable reference, and with the sliding of slider 1 21 and slider 2 24 in slide groove 1 11 and slide groove 2 23 respectively, as well as the locking effect of adjusting rod 27 and fixing bolt 28, it can locate the slope, intercept or fixed point of a straight line.

[0024] Specifically, slider 21 slides along groove 11 (x-axis direction) of base frame 10, and slider 24 slides along groove 23 (y-axis direction) of bracket 22. The two work together to accurately locate the intercept or fixed point of the straight line, and the slope can be locked by fine adjustment of the angle of adjustment rod 27.

[0025] In one embodiment of this utility model, such as Figures 1-2 As shown, the base frame 10 is also provided with a fixing component 30 at its end. The fixing component 30 includes an adjusting column 31. The base frame 10 has a fixing hole 12 at its end. The adjusting column 31 is threaded to the inside of the fixing hole 12. A permanent magnet 32 ​​is fixedly connected to the lower end of the adjusting column 31. By rotating the adjusting column 31, it moves within the fixing hole 12, changing the distance between the permanent magnet 32 ​​and the whiteboard, thereby achieving a stable fixation between the base frame 10 and the whiteboard.

[0026] In one embodiment of this utility model, such as Figure 2 As shown, the cross-sections of slider 1 21 and slider 2 24 are convex, and the inner sides of slide groove 1 11 and slide groove 2 23 are matched with slider 1 21 and slider 2 24 to ensure the stability of sliding.
