Description

Technical Field

[0001] This utility model relates to the field of teaching tools technology, specifically an economic and financial teaching tool. Background Technology

[0002] Economics studies the laws governing human economic activities, specifically the laws governing the creation, transformation, and realization of value—the laws of economic development. Finance, on the other hand, focuses on the study of economic activities in the financial and monetary markets. Therefore, both economics and finance require extensive analysis of charts and graphs, as well as the analysis of trends in various business operations. Display boards are typically used in teaching, and these are generally divided into hanging boards and those with stands. Hanging boards are more commonly used due to their simpler structure. Lecturers use them to write analyses or post photos, resulting in a lot of writing and drawing, which necessitates constant cleaning and wiping of the display boards.

[0003] To enhance the stability of the mounting plate during use, a patent document with publication number CN214796407U describes a method where the plate is attached to a wall-mounted hook using a hook. Furthermore, the connecting spring design ensures a tighter contact between the L-shaped plates on both sides of the slider and the guide groove, thereby improving the slider's stability and consequently enhancing the stability of the magnetic whiteboard during installation and use.

[0004] Theoretically, the implementation of the aforementioned technical structure should facilitate the installation of the mounting board. However, according to the description in the disclosed technical content, when the magnetic whiteboard needs to be wiped, the writing on the magnetic whiteboard can be cleaned by moving the blackboard eraser. However, due to the one-piece design of the blackboard eraser and its length limitation, the blackboard eraser may accidentally erase writing that does not need to be wiped when wiping the magnetic whiteboard. Furthermore, when the teacher pastes a photo on the magnetic whiteboard, the one-piece design of the blackboard eraser will come into contact with the photo when wiping the magnetic whiteboard. Moving the blackboard eraser can easily cause the photo to fall off the magnetic whiteboard, thus resulting in certain limitations in the use of the blackboard eraser. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an economic and financial teaching tool that features a segmented blackboard eraser that replaces the single-piece blackboard eraser, improves the flexibility of the blackboard eraser during use, and avoids accidental erasure of blackboard writing.

[0024] 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.

[0025] Please see Figure 1 , Figure 2 and Figure 4 An economics and finance teaching tool includes a whiteboard 1. Blackboard erasers 2 are located at the top and bottom of the front of the whiteboard 1 for cleaning writing. A mounting block 3 is magnetically attached to the side of the eraser 2 away from the whiteboard 1. This magnetic connection facilitates both mounting and detaching the eraser 2 from the mounting block 3, making it easier to replace a soiled eraser 2 and improving its cleaning effect on the whiteboard 1. A lifting assembly 4 is located on the back of the mounting block 3 for resetting the eraser 2 after use. The lifting assembly 4 enables vertical movement of the eraser 2 and allows for easy use of the eraser 2. After the reset is completed, a telescopic rod 6 is fixedly installed on the back of the lifting component 4. The end of the telescopic rod 6 away from the lifting component 4 is connected to the cylinder 8 through the movable component 7. The installation of the movable component 7 serves to connect the telescopic rod 6 and the cylinder 8. A movable block 9 is fixedly installed at the rear end of the cylinder 8, and the inner wall of the movable block 9 is slidably connected to the whiteboard 1. The movement of the movable block 9 can realize the horizontal movement of the blackboard eraser 2. Clamping components 10 are respectively provided on the left and right sides of the whiteboard 1. The clamping components 10 are clamped to the bracket 12 by fastening bolts 11, and the back of the bracket 12 is fixed to the wall. The installation of the fastening bolts 11 serves to connect the clamping components 10 and the bracket 12.

[0026] Extension plates 13 located below clamping assembly 10 are fixedly installed on the left and right sides of whiteboard 1, respectively. Slide grooves 14 are provided on the front and back of extension plates 13 and whiteboard 1, respectively. The slide grooves 14 provide space for the movement of slider 15. The slide grooves 14 on extension plates 13 and whiteboard 1 are internally connected. Slide slider 15 is slidably connected to the inner wall of slide groove 14, and the outer end of slider 15 is fixedly connected to the inner wall of moving block 9.

[0027] Please see Figure 3 , Figure 5 and Figure 7 The lifting assembly 4 includes a round rod 401, a first spring 402, and a sleeve 403. The outer wall of the round rod 401 is movably sleeved with the inner wall of the sleeve 403, and the inner side of the first spring 402 is movably sleeved with the outer wall of the round rod 401.

[0028] A lower base plate 22 is fixedly installed at the lower end of the round rod 401, and the back of the lower base plate 22 is fixedly connected to the front of the mounting block 3. The upper end of the lower base plate 22 is fixedly connected to the lower end of the round rod 401 and the lower end of the first spring 402. The rebound of the first spring 402 can realize the reset of the blackboard eraser 2, and the stretching of the first spring 402 can realize the vertical movement of the blackboard eraser 2. An upper end plate 16 is fixedly sleeved on the outer wall of the lower end of the sleeve 403. The lower end of the upper end plate 16 is fixedly connected to the upper end of the first spring 402. The rear end of the upper end plate 16 is fixedly connected to the front end of the telescopic rod 6. The upper end plate 16 is set to connect the telescopic rod 6 and the sleeve 403.

[0029] Please see Figure 6 and Figure 8 The movable component 7 includes a movable plate 701, a second spring 702, and a limiting block 703. The front of the movable plate 701 is fixedly connected to the rear end of the telescopic rod 6, and the back of the movable plate 701 is fixedly connected to the front end of the second spring 702. The second spring 702 connects the cylinder 8 to the movable plate 701. The rear end of the second spring 702 is fixedly connected to the inner wall of the cylinder 8. The limiting blocks 703 are evenly distributed on the outer wall of the movable plate 701, and the outer wall of the limiting block 703 away from the movable plate 701 is slidably connected to the inner wall of the cylinder 8. The movement of the limiting block 703 within the cylinder 8 strengthens the stability of the telescopic rod 6's telescopic movement.

[0030] The clamping assembly 10 includes an upper clamping plate 101 and a lower clamping plate 102. Anti-slip pads 19 are fixedly connected to the inner walls of the upper clamping plate 101 and the lower clamping plate 102, respectively. The anti-slip pads 19 increase the friction between the clamping assembly 10 and the contact surface of the bracket 12. Upper horizontal plates 17 are fixedly installed on both the left and right sides of the upper clamping plate 101. A protrusion 21 is fixedly installed at the lower end of the upper horizontal plate 17. Lower horizontal plates 18 located below the upper horizontal plate 17 are fixedly connected to the left and right sides of the lower clamping plate 102. The lower horizontal plate 18 and the upper horizontal plate 17 are connected by fastening bolts 11. A groove 5 is opened on the upper end surface of the lower horizontal plate 18. The inner wall of the groove 5 is movably engaged with the outer wall of the protrusion 21. A connecting rod 20 is fixedly installed at the lower end of the lower clamping plate 102. The lower end of the connecting rod 20 is fixedly connected to the outer side of the extension plate 13.

[0031] Working principle: In use, firstly, install the upper clamping plate 101 on the upper end face of the bracket 12, and install the lower clamping plate 102 on the lower end face of the bracket 12. At this time, the protrusion 21 is inserted into the groove 5. Then, using the fastening bolt 11, move the upper horizontal plate 17 from above to the lower horizontal plate 18 by rotation. At this time, the upper horizontal plate 17 can fix the upper clamping plate 101 and the lower clamping plate 102 on the bracket 12, achieving the installation effect of the whiteboard 1. Then, install the blackboard eraser 2 on the back of the mounting block 3 by magnetic attraction. When the teacher needs to use the blackboard eraser 2 to clean the writing on the whiteboard 1, move the moving block 9 at the upper or lower end of the whiteboard 1. At this time, the sliding block 15 in the slide groove 14 reinforces the movement of the moving block 9. To ensure stability, when the whiteboard 1 is moved horizontally to the designated erasing position, the blackboard eraser 2 is moved to the erasing position and pushed towards the whiteboard 1. At this time, the compression of the second spring 702 drives the telescopic rod 6 to move into the cylinder 8 through the connection of the movable plate 701 until the blackboard eraser 2 contacts the whiteboard 1. Then, the extension of the first spring 402 allows for vertical erasing of the writing on the whiteboard 1, while the movement of the moving block 9 allows for horizontal erasing of the writing on the whiteboard 1. Finally, after the blackboard eraser 2 is used, the retraction of the first spring 402 resets the blackboard eraser 2, and the movement of the moving block 9 moves the blackboard eraser 2 to the extension plate 13 to prevent the blackboard eraser 2 from obscuring the content on the whiteboard 1.
