Description

Technical Field

[0001] This utility model relates to the field of teaching aids technology, specifically a physics problem solving display stand. Background Technology

[0002] The core purpose of solving difficult physics problems is to reveal the essence of natural laws, verify the correctness of theoretical models, and cultivate the ability to solve complex problems through deep thinking training and logical deduction. Difficult physics problems often involve phenomena under multiple coupled factors or extreme conditions (such as high-speed motion, microscopic quantum effects, and strong gravitational fields). Through calculation, superficial interference can be stripped away to uncover hidden physical relationships.

[0003] Currently, physics teaching requires blackboard writing to demonstrate formulas for solving physics problems. However, when dealing with complex physics problems, teachers often write a lot. While existing blackboards can increase the writing surface area, the angle of this increased area cannot be adjusted. Because of the increased blackboard area, the sides of the blackboard tend to reflect light, making it difficult for students to see clearly and hindering the teaching process. Furthermore, the lack of a proper rotation and adjustment mechanism makes it inconvenient for students to view the material from multiple angles in public spaces, thus the presentation effect needs improvement. Additionally, erasing a fully written blackboard is time-consuming and easily leaves chalk dust on hands. Utility Model Content

[0004] The purpose of this invention is to provide a physics problem solving demonstration rack to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a physics problem solving display stand, including a calculation board, wherein the calculation board provides a writing surface;

[0006] An assembly rack is used to mount the calculation boards, which are distributed horizontally or vertically.

[0007] When the calculation board is laid out horizontally, it is used to write and display the calculation process;

[0008] When the calculation board is distributed vertically, the horizontal proportion should be reduced.

[0009] It also includes a support frame for supporting the assembly frame, the assembly frame being detachably connected to the support frame, the assembly frame being rotatable and adjustable on the support frame, thereby adjusting the display orientation of the calculation board.

[0010] In a further embodiment, the assembly frame has a top cap, a first plug sleeve, and a connecting rod. The top cap and the first plug sleeve are coaxially distributed, and the two ends of the connecting rod are fixedly connected to the opposite side wall edges of the top cap and the first plug sleeve.

[0011] The support frame includes an upright and a base plate fixed to the bottom wall of the upright. The plug sleeve is rotatably sleeved on the outer wall of the upright, and the bottom wall of the top cap has a rotating groove for rotatably inserting into the top wall of the upright.

[0012] In a further embodiment, the calculation board includes a writing board and a frame embedded in the four perimeter sidewalls of the writing board, and the two long sidewalls of the frame are provided with grooves.

[0013] The top cap and the radial sidewall of the first insertion sleeve are both fixed with a support plate at their ends that are far apart from each other. The two support plates are provided with multiple rotating pins on their opposite sidewalls. The two long sidewalls of the calculation plate are respectively slidably attached to the opposite sidewalls of the two support plates, and the rotating pins are slidably inserted into the corresponding grooves.

[0019] A wiping plate is fixed to the side wall of the flip-up panel facing the calculation board, and a cleaning cloth for wiping the calculation board is pasted on the surface of the wiping plate.

[0020] In a further embodiment, a limiting pressure plate is provided on the upper end face of the protrusion. When the flip plate is in a vertical state, the limiting pressure plate rotates around the position of the protrusion, so that the bottom wall of the end of the limiting pressure plate can rotate and press against the top wall of the flip plate.

[0021] A limiting block is fixed to the side wall of the end of the tray connected to the insertion sleeve. The limiting block has a snap-fit ​​notch. A snap-fit ​​block is fixed to the bottom wall of the flip plate and snaps into the snap-fit ​​notch.

Detailed Implementation

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] This embodiment provides a physics problem solving demonstration stand, such as... Figure 1 and Figure 6 As shown, the calculation board includes a writing board 2 and a frame 3 embedded in the four sides of the writing board 2. The two long side walls of the frame 3 are provided with grooves 31. The writing board 2 of the calculation board provides a writing surface. The frame 3 is used to reinforce the writing board 2 on the side walls of the writing board 2.

[0042] The assembly rack was also disclosed, on which the calculation boards are mounted. The calculation boards can be distributed horizontally or vertically, specifically, such as... Figure 2 As shown, the assembly frame has a top cap 4, a plug sleeve 6, and a connecting rod 7. The top cap 4 and the plug sleeve are coaxially distributed, and the two ends of the connecting rod 7 are fixedly connected to the opposite side wall edges of the top cap 4 and the plug sleeve 6. At the same time, the ends of the radial side walls of the top cap 4 and the plug sleeve 6 that are far apart from each other are fixed with a support plate 41. The opposite side walls of the two support plates 41 are rotatably provided with multiple rotating pins 42. The two long side walls of the writing board 2 of the calculation board are slidably attached to the opposite side walls of the two support plates 41, and the rotating pins 42 are slidably inserted into the corresponding grooves 31.

[0043] Multiple rotating pins 42 are rotatably arranged on the same tray 41. The purpose of these rotating pins 42 is to provide support for the frame 3 to maintain a horizontal and stable state on the two trays 41 by sliding and inserting them into the groove 31. Compared with only one rotating pin 42, multiple rotating pins 42 can form multiple support points on the same horizontal plane, thereby enhancing the installation support strength of the writing board 2.

[0044] It also includes support frames for supporting the assembly rack, such as Figure 1 As shown, the assembly frame and the support frame are detachably connected. The support frame includes an upright 1 and a base 11 fixed to the bottom wall of the upright 1. The base 11 provides a support base for the upright 1. The plug sleeve 6 is rotatably sleeved on the outer wall of the upright 1, and the bottom wall of the top cap 4 has a rotating groove for rotatably plugging into the top wall of the upright 1.

[0045] The two long side walls of the writing board 2 of the calculation board slide against the opposite side walls of the two support plates 41 respectively, and the rotating pin 42 slides into the corresponding groove 31. At the same time, the insertion sleeve 6 is aligned with the upper end of the upright 1 and put down on the upright 1. As the insertion sleeve 6 falls down along the outer wall of the upright 1, the top cap 4 can be inserted into the outer wall of the top of the upright 1. The calculation board is then suspended on the support frame by the assembly frame.

[0046] At this time, the long side wall of writing board 2 is like Figure 1 The state distribution is shown. When the calculation board is laid out horizontally, it is used to write and display the calculation process.

[0047] When solving challenging physics problems, the teacher can demonstrate and deduce the solution process on the writing board 2 simply by holding a piece of chalk. Since the top cap 4 is rotatably fitted onto the top of the upright 1, and the connecting sleeve 6 is rotatably fitted onto the outer wall of the upright 1, the teacher can move the writing board 2 during the calculation process. This causes the writing board 2, along with the top cap 4 and the connecting sleeve 6, to rotate around the upright 1, changing the display orientation of the writing board 2. This makes it easier to display the solution to students in all directions of the classroom and ensures that students can see it clearly.

[0048] Of course, during the demonstration and calculation process, in order to enhance the support stability of the support frame, multiple pull-out grooves are provided on the radial side wall of the chassis 11. A foot 12 is slidably inserted into each pull-out groove. A connecting hole communicating with the pull-out groove is provided on the upper surface of the chassis 11. A sliding post 13, which is slidably engaged with the connecting hole, is fixed to the upper wall of one end of the foot 12 located within the pull-out groove. For example... Figure 1 and Figure 3 As shown, during use, the base 12 is pulled out of the pull-out slot towards the side away from the center of the chassis 11, thereby expanding the support range of the chassis 11 and enhancing the overall support stability of the support frame. Simultaneously, the sliding column 13 slides synchronously along the connecting hole, preventing the base 12 from being completely pulled out of the pull-out slot. When not in use, the base 12 can be pushed back into the pull-out slot to reduce its footprint on the ground.

[0049] When the problem is solved, if the writing board 2 on the calculation board is horizontally distributed, it will occupy horizontal space. Therefore, when the calculation board is vertically distributed, the horizontal proportion will be reduced. The specific solution is as follows: Figure 4 and Figure 5 As shown, the assembly frame also includes a second plug-in sleeve 5. The axis of the second plug-in sleeve 5 is perpendicular to the connecting rod 7 and they are fixedly welded together. Here, the inner diameter of the second plug-in sleeve 5 is the same as the outer diameter of the upright 1. When the second plug-in sleeve 5 is fitted onto the outer wall of the upright 1, the two long side walls of the calculation board are in the vertical direction. In this way, the lateral proportion of the calculation board is greatly reduced.

[0050] In this embodiment, further, such as Figure 7 , Figure 8 and Figure 9 As shown, a protrusion 43 is fixed to the upper surface of the support plate 41 connected to the top cap 4. The protrusion 43 has a rotating hole, and an I-beam shaft 83 is rotatably inserted into the rotating hole. A flip plate 8 is fixed to the end of the I-beam shaft 83. A wiping plate 81 is fixed to the side wall of the flip plate 8 facing the calculation board. A cleaning cloth for wiping the calculation board is attached to the surface of the wiping plate 81. The flip plate 8 can swing between the horizontal and vertical directions with the I-beam shaft 83 as the rotation center. In this way, as long as the flip plate 8 is flipped to the vertical position, the cleaning cloth can be brought into contact with the surface of the writing board 2 through the wiping plate 81. When the sliding groove 31 of the frame 3 is pushed horizontally along the outer wall of the rotating pin 42, the entire calculation board can slide horizontally between the two support plates 41 to adjust its position. The writing on the surface of the writing board 2 can be wiped off by the cleaning cloth.

[0051] By using a horizontal pushing and extending method, the calculation board is pushed back and forth horizontally once or twice. The writing surface of the calculation board passes through the erasing plate 81, which quickly erases the writing so that it can be used again. This achieves quick erasing of the calculation board while avoiding chalk dust from soiling the teacher's hands and clothes.

[0052] To improve wiping effectiveness, the wiping plate 81 has a corrugated elastic structure (it can be made of PVC plastic, which has good elastic deformation characteristics), and the two side walls are bent and fixedly connected to the flip plate 8. When the flip plate 8 is in a vertical position, the corrugated elastic structure of the wiping plate 81 has elasticity, pressing the cleaning cloth tightly against the surface of the writing board 2. As long as the writing board 2 moves horizontally back and forth, the cleaning cloth can quickly wipe away the writing on the surface of the writing board 2.

[0053] The I-beam shaft 83 is fitted with a torsion spring located in the rotating hole. One end of the torsion spring is fixedly inserted into the inner wall of the rotating hole, and the other end is fixedly inserted into the end side wall of the I-beam shaft 83. The torsion spring has torsional potential energy, which in turn flips the flipping rod to the horizontal direction under normal conditions.

[0054] In addition, such as Figure 8 and Figure 10 As shown, a limiting pressure plate 44 is rotatably provided on the upper end face of the protrusion 43. When the flip plate 8 is flipped to a vertical state, the limiting pressure plate 44 rotates around the position of the protrusion 43, and can rotate the bottom wall of the limiting pressure plate 44 onto the top wall of the flip plate 8. At the same time, a limiting block 9 is fixed to the side wall of the end of the tray 41 connected to the insertion sleeve 6. The limiting block 9 has a snap-fit ​​notch, and a snap-fit ​​block 82 is fixed to the bottom wall of the flip plate 8 to snap into the snap-fit ​​notch. That is to say, when it is necessary to wipe away the writing on the writing board 2, the flip plate 8 is flipped to a vertical state. At this time, the snap-fit ​​block 82 can follow the flipped flip plate 8 and snap into the snap-fit ​​notch. At the same time, the limiting pressure plate 44 rotates around the position of the protrusion 43, and the bottom wall of the limiting pressure plate 44 rotates and presses onto the top wall of the flip plate 8. In this way, the flip plate 8 is stably in a vertical state and will not be affected by the torque of the torsion spring to flip back to a horizontal state, causing the wiping plate 81 to detach from the writing board 2.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
