Description

Technical Field

[0001] This utility model relates to the field of teaching demonstration device technology, specifically a multi-dimensional linkage coordinate system positioning demonstration ruler. Background Technology

[0002] In the field of mathematics and physics teaching, the spatial abstract concept of three-dimensional coordinate system has always been a teaching challenge. Traditional teaching often relies on planar drawings or static models, which makes it difficult to intuitively demonstrate the dynamic positioning process of coordinate points.

[0003] As proposed in announcement number CN209343606U, a novel three-dimensional coordinate teaching demonstration stand is described. Although the stand achieves spatial point positioning through a sliding sleeve structure (Y-axis sliding sleeve, X-axis sliding sleeve, Z-axis sliding sleeve), each coordinate axis (Y-axis, X-axis, Z-axis) needs to be adjusted individually, making operation cumbersome and unable to simultaneously demonstrate the spatial linkage relationship of points. Furthermore, it relies on damped sliding, such as the sliding connection between the indicator rod and the connecting sleeve, which is prone to offset or rebound, making it difficult to achieve and maintain accurate coordinate positioning, thus affecting the accuracy of the demonstration. Moreover, the split design results in weak overall rigidity and poor stability, which may cause shaking during operation, further affecting the demonstration accuracy and service life. This device mainly solves the problem of static positioning of coordinate points, but it is insufficient in intuitively displaying the dynamic spatial trajectory of points and driving three-axis synchronous movement through single-point operation.

[0004] In summary, a multi-dimensional linkage coordinate system positioning demonstration ruler is proposed to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a multi-dimensional linkage coordinate system positioning demonstration ruler. It features the ability to change the position of coordinate points through multi-axis linkage and to perform three-axis synchronous movement through single-point operation, intuitively displaying the spatial trajectory of coordinate points. This makes operation more convenient, demonstration more accurate, and the integrated frame extends the service life. It solves the problems of existing technologies, such as cumbersome operation and inability to synchronously demonstrate the spatial linkage relationship of points, inaccurate positioning affecting the accuracy of the demonstration, insufficient rigidity further affecting the demonstration precision and service life, and insufficient ability to intuitively display the dynamic spatial trajectory of points and drive three-axis synchronous movement through single-point operation.

[0007] (II) Technical Solution

[0008] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A multi-dimensional linkage coordinate system positioning demonstration ruler includes a base plate. A Z-axis guide rod is fixedly connected to the top of the base plate, perpendicular to it and located at its upper left corner. A limit ring is fixedly connected to the outer side of the lower end of the Z-axis guide rod. An auxiliary guide rod is fixedly connected to the top of the base plate, located in front of and to the right of the Z-axis guide rod and parallel to it. The same right-angle support frame is fixedly connected to the outer side of the upper end of the Z-axis guide rod and the auxiliary guide rod. A Z-axis sliding sleeve adapted to the limit ring is sleeved on the outer side of the Z-axis guide rod. The auxiliary guide rod in front of the Z-axis sliding sleeve is fixedly connected to the front side of the auxiliary guide rod. A sliding Y-axis guide rod is provided, and an X-axis guide rod is fixedly connected to the right side of the Z-axis sliding sleeve and slidably connected to the auxiliary guide rod on its right side. Both the Y-axis guide rod and the X-axis guide rod have sliding grooves at their tops. Y-axis sliding sleeves and X-axis sliding sleeves that are slidably connected to the top sliding grooves are respectively fitted on the outer sides of the Y-axis guide rod and the X-axis sliding sleeve. An X-axis sliding guide assembly perpendicular to the Y-axis guide rod is provided on the right side of the Y-axis sliding sleeve. A Y-axis sliding guide assembly perpendicular to the X-axis guide rod and passing through the X-axis sliding guide assembly is provided on the front side of the X-axis sliding sleeve. The X-axis sliding guide assembly and the Y-axis sliding guide assembly are fitted with the same intersection assembly that is slidably connected to them.

[0009] The beneficial effects of this utility model are:

[0010] This multi-dimensional, interconnected coordinate system positioning demonstration ruler treats the intersection component as a coordinate point. By moving the Y-axis sliding guide component, the X-axis sliding sleeve and the intersection component can slide along the X-axis guide rod and the X-axis sliding guide component respectively, thus changing the X value of the coordinate point. Similarly, moving the X-axis sliding guide component causes the Y-axis sliding sleeve and the intersection component to slide along the Y-axis guide rod and the Y-axis sliding guide component respectively, thereby changing the Y value of the coordinate point. Moving the Z-axis sliding sleeve to slide outside the Z-axis guide rod simultaneously causes the Y-axis guide rod and the X-axis guide rod to slide along the auxiliary guide rod, thus changing the Z value of the coordinate point. A right-angle support frame enhances the rigidity of the device, ensuring its stability. The frame is stable and allows direct manipulation of the intersection component, enabling it to move within the XY plane. During this process, the motion is transmitted to the Z-axis system through the mechanical coupling of the X-axis and Y-axis sliding guide components. The displacement of the X-axis and Y-axis sliding sleeves pulls the Z-axis sliding sleeve, which slides along the Z-axis guide rod. Simultaneously, it drives the Y-axis and X-axis guide rods to rise and fall along the auxiliary guide rod, changing the Z-coordinate of the intersection component. This allows for multi-axis linkage to change the coordinate point position and single-point operation for synchronous three-axis movement, providing a clear visual display of the coordinate point's spatial trajectory. This makes operation more convenient, demonstrations more accurate, and extends the service life of the integrated frame.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the X-axis sliding guide assembly includes an X-axis guide post and a strip-shaped hole. The right side of the Y-axis sliding sleeve is fixedly connected to an X-axis guide post perpendicular to the Y-axis guide rod. A strip-shaped hole extending to the rear side of the X-axis guide post is opened on the front side of the X-axis guide post.

[0013] Furthermore, the Y-axis sliding guide assembly includes a Y-axis guide post and a flat surface. The front side of the X-axis sliding sleeve is fixedly connected to a Y-axis guide post that is perpendicular to the X-axis guide rod and passes through the X-axis guide post through a strip-shaped hole. The top and bottom of the Y-axis guide post are provided with flat surfaces that are adapted to the strip-shaped hole.

[0014] Furthermore, the intersection component includes a sphere, a circular hole, and a rectangular hole. The same sphere is fitted on the outer side of the X-axis guide post and the Y-axis guide post. A circular hole extending to the left side of the sphere and adapted to the X-axis guide post is opened on the right side of the sphere. A rectangular hole extending to the rear side of the sphere and communicating with the circular hole and adapted to the outer flat surface of the Y-axis guide post is opened on the front side of the sphere.

[0015] The beneficial effects of adopting the above-mentioned further solution are as follows: the design of the strip hole allows the Y-axis guide post to pass through, forming a mechanical coupling. When the ball or related components are moved, the X-axis guide post guides the Y-axis sleeve to slide smoothly along the Y-axis guide rod, avoiding offset or rebound. The precise matching of the flat surface and the strip hole ensures that the Y-axis guide post passes through without jamming, achieving low-friction sliding, solving the offset problem that is prone to occur in traditional devices, and improving the coordinate positioning accuracy. When the ball is moved, the movement of the Y-axis guide post is transmitted to the X-axis guide post through the flat surface, and then coupled to the Z-axis sleeve through the Y-axis guide rod and the X-axis guide rod, so that the Z-axis sleeve slides along the Z-axis guide rod, realizing the three-axis synchronous demonstration of spatial trajectory, intuitively displaying the spatial trajectory of coordinate points, avoiding the cumbersome independent adjustment of each axis. The ball is guided by the round hole and the rectangular hole, which allows the ball to move freely in the XY plane. At the same time, the fit between the rectangular hole and the flat surface ensures no rotational deviation. On this basis, the tight fit between the round hole and the X-axis guide post can eliminate the damping sliding error of traditional devices.

[0016] Furthermore, the outer sides of the Z-axis guide rod, Y-axis guide rod, and X-axis guide rod are all engraved with scale lines, and the scale lines increase from the side closest to the Z-axis sliding sleeve to the other side.

[0017] Furthermore, the top of the substrate is engraved with a rectangular grid that matches the outer scale lines of both the Y-axis guide rod and the X-axis guide rod;

[0018] Furthermore, the outer sides of the Z-axis sliding sleeve, Y-axis sliding sleeve, and X-axis sliding sleeve are all threaded with limiting bolts that extend into their interiors and abut against the outer sides of the Z-axis guide rod, Y-axis guide rod, and X-axis guide rod, respectively.

[0019] The advantages of adopting the above-mentioned further solution are that the scale lines provide a linear coordinate reference, the top of the substrate is engraved with a rectangular grid that matches the scale lines on the outer sides of the Y-axis guide rod and the X-axis guide rod, forming an integrated reference system of planar and three-dimensional coordinates, improving the intuitiveness of the demonstration, and the limiting bolts realize the position locking of the Z-axis slide sleeve, Y-axis slide sleeve and X-axis slide sleeve, ensuring no accidental displacement.

The top of both the Y-axis guide rod 7 and the X-axis guide rod 8 is provided with a sliding groove 9. The outer sides of the Y-axis guide rod 7 and the X-axis guide rod 8 are respectively fitted with a Y-axis sliding sleeve 10 and an X-axis sliding sleeve 11 that are slidably connected to the top sliding groove 9. The right side of the Y-axis sliding sleeve 10 is provided with an X-axis sliding guide assembly 12 that is perpendicular to the Y-axis guide rod 7. The front side of the X-axis sliding sleeve 11 is provided with a Y-axis sliding guide assembly 13 that is perpendicular to the X-axis guide rod 8 and passes through the X-axis sliding guide assembly 12. The outer sides of the X-axis sliding guide assembly 12 and the Y-axis sliding guide assembly 13 are fitted with the same intersection assembly 14 that is slidably connected to them.

[0028] The X-axis sliding guide assembly 12 includes an X-axis guide post 121 and a strip hole 122. The right side of the Y-axis sliding sleeve 10 is fixedly connected to the X-axis guide post 121, which is perpendicular to the Y-axis guide rod 7. The front side of the X-axis guide post 121 is provided with a strip hole 122 extending to its rear side.

[0029] The Y-axis sliding guide assembly 13 includes a Y-axis guide post 131 and a flat surface 132. The front side of the X-axis sliding sleeve 11 is fixedly connected to a Y-axis guide post 131 that is perpendicular to the X-axis guide rod 8 and passes through the X-axis guide post 121 through the strip hole 122. The top and bottom of the Y-axis guide post 131 are provided with flat surfaces 132 that are adapted to the strip hole 122.

[0030] The intersection assembly 14 includes a sphere 141, a circular hole 142 and a rectangular hole 143. The same sphere 141 is sleeved on the outer side of the X-axis guide post 121 and the Y-axis guide post 131. A circular hole 142 extending to the left side and adapted to the X-axis guide post 121 is opened on the right side of the sphere 141. A rectangular hole 143 extending to the rear side and communicating with the circular hole 142 and adapted to the outer flat surface 132 of the Y-axis guide post 131 is opened on the front side of the sphere 141.

[0031] The outer sides of the Z-axis guide rod 2, Y-axis guide rod 7 and X-axis guide rod 8 are all engraved with scale lines 15, which increase from the side closest to the Z-axis sliding sleeve 6 to the other side.

[0032] The top of the substrate 1 is engraved with a rectangular grid 16 that matches the outer scale lines 15 of the Y-axis guide rod 7 and the X-axis guide rod 8.

[0033] The outer sides of the Z-axis sliding sleeve 6, Y-axis sliding sleeve 10, and X-axis sliding sleeve 11 are all threaded with limiting bolts 17 that extend into their interiors and abut against the outer sides of the Z-axis guide rod 2, Y-axis guide rod 7, and X-axis guide rod 8, respectively.

[0034] Working principle:

[0035] Step 1: Treat sphere 141 as a coordinate point. Adjust the Z-axis coordinate of the coordinate point. Move the Z-axis sliding sleeve 6 up and down along the Z-axis guide rod 2. The limit ring 3 prevents slippage. At the same time, drive the Y-axis guide rod 7 and X-axis guide rod 8 to move up and down synchronously along the auxiliary guide rod 4 to change the Z-coordinate value of sphere 141. Adjust the X-axis coordinate of the coordinate point. Move the Y-axis sliding guide component 13 to drive the X-axis sliding sleeve 11 to slide along the X-axis guide rod 8. The slide groove 9 limits the movement. At the same time, drive the sphere 141 to move along the X-axis guide column 121 to change the X-coordinate. Adjust the Y-axis coordinate of the coordinate point. Move the X-axis sliding guide component 12 to drive the Y-axis sliding sleeve 10 to slide along the Y-axis guide rod 7. At the same time, drive the sphere 141 to move along the Y-axis guide column 131 to change the Y-coordinate.

[0036] Step 2: Single-point operation synchronously drives the three axes. Directly move the ball 141 to allow it to move freely in the XY plane. The ball 141 slides along the X-axis guide post 121 through the circular hole 142, and simultaneously slides along the Y-axis guide post 131 through the rectangular hole 143. The rectangular hole 143 is adapted to the flat surface 132 of the Y-axis guide post 131 to limit rotational deviation. Based on this, the tight fit between the circular hole 142 and the X-axis guide post 121 can eliminate the damping sliding error of the traditional device. The displacement is transmitted to the Z-axis sliding sleeve 6, causing the Z-axis sliding sleeve 6 to slide along the Z-axis guide rod 2. At the same time, it drives the Y-axis guide rod 7 and the X-axis guide rod 8 to rise and fall along the auxiliary guide rod 4, realizing synchronous change of the Z coordinate. This achieves multi-axis linkage to change the position of the coordinate point, realizes single-point operation to perform synchronous movement of the three axes, and intuitively displays the spatial trajectory of the coordinate point, making the operation more convenient and the demonstration more accurate.

[0037] Step 3: Tighten the limiting bolts 17 on the outside of the Z-axis sliding sleeve 6, Y-axis sliding sleeve 10 and X-axis sliding sleeve 11 to abut the guide rod in the fixed position. Observe the scale lines 15 on the outside of the Z-axis guide rod 2, Y-axis guide rod 7 and X-axis guide rod 8. Combine the rectangular grid 16 on the top of the substrate 1 to verify the accuracy of the planar coordinates, form an integrated reference system of planar and three-dimensional coordinates, and improve the intuitiveness of the demonstration.
