Description
Technical Field
[0001] This invention relates to the field of educational supplies, and more specifically, to a teaching device for business administration majors. Background Technology
[0002] Business Administration is one of the most common management majors in a market economy, generally referring to the management of industrial and commercial enterprises. (The English name is literally translated as Industry & Business Administration, but it is usually translated as Business Administration). Business Administration is a discipline that studies the basic theories and general methods of economic management of industrial and commercial enterprises, mainly including two aspects: the formulation of business strategies and the management of internal behavior. Business Administration is a highly applied major. Its goal is to use modern management methods and tools, based on the basic theories of management, economics, and accounting, to conduct effective enterprise management and business decision-making, thereby ensuring the survival and development of enterprises.
[0003] In business administration education, traditional teaching devices cannot reasonably extend and lift according to human mechanics, which limits their ability to analyze and simulate cases. In addition, other existing patent technologies, such as CN110689772A, require a separate storage device to store simulated block parts and additional fixing mechanisms to arrange and form simulated blocks. To address these issues, we propose a teaching device for business administration majors. Summary of the Invention
[0004] 1. Technical problems to be solved
[0005] Traditional teaching devices, which lack the ability to extend and lift in a manner appropriate to human biomechanics, present limitations in case analysis and simulation. The present invention aims to provide a teaching device for business administration majors that allows for reasonable extension and lifting based on the human body, enhancing teaching effectiveness through case analysis and simulation.
[0006] 2. Technical Solution
[0007] To solve the above problems, the present invention adopts the following technical solution:
[0008] A teaching device for business administration includes a base. An octagonal support column is fixedly connected to the upper end of the base. A fixing groove is carved into the upper end of the octagonal support column. A motor slot is carved into the lower inner wall of the fixing groove. A motor is fixedly connected to the lower inner wall of the motor slot. A lead screw is rotatably connected to the upper end of the motor. An octagonal frustum support column is rotatably connected to the circumferential surface of the lead screw. A table is fixedly connected to the upper end of the octagonal frustum support column. A lower limit pad is fixedly connected to the lower inner wall of the fixing groove. Four guide blocks are fixedly connected to the upper end of the lower limit pad. The octagonal inner wall surface of the fixing groove is fixed with four evenly distributed upper limit blocks. The lower ends of the four upper limit blocks are all fixedly connected to upper contact pressure switches. Contact pressure blocks are provided between the four upper limit blocks and the four upper contact pressure switches. The four contact pressure blocks are all fixedly connected to the octagonal frustum support column. The octagonal inner wall of the fixing groove is evenly distributed with four guide pulley grooves. The octagonal frustum support column is evenly distributed with four guide fixing blocks. The front ends of the four guide fixing blocks are rotatably connected to four guide pulley grooves. The four guide fixing blocks slide within the guide pulley grooves.
[0009] The octagonal support column has eight evenly distributed hidden grooves carved on its octagonal surface. Seat support frames are rotatably connected between the left and right inner walls of each of the eight hidden grooves. Seats are rotatably connected to the upper ends of the eight seat support frames. A first magnetic block is installed on the top of the seat body. A simulation board receiving groove and seven simulation block placement grooves are carved at the upper end of the table. A simulation board is inserted between the inner walls of the simulation board receiving groove. Evenly distributed simulation block slots are carved at the upper end of the simulation board. Multiple simulation blocks are inserted between the left and right inner walls of the seven simulation block placement grooves. The two ends of the simulation block body are cylindrical rods, and a second magnetic block is embedded within each of the two cylindrical rods at both ends. The two ends of the second magnets have opposite magnetic poles on their farthest sides. The contour of the simulation block slot matches the end of the cylindrical rod of the simulation block. Multiple third magnetic blocks, which are columnar magnets, are arranged between the simulation block slots on the simulation board body and can be attracted to the simulation board body with their magnetic poles facing in opposite directions.
[0010] Each of the eight seats has a handle fixedly connected to its front end.
[0011] Each of the eight seats has a sponge pad fixedly attached to its upper end.
[0012] The motor is a three-phase asynchronous motor.
[0013] Control buttons are fixedly connected to the upper part of the table.
[0014] The surfaces of the upper limit block and the lower limit pad are covered with rubber sleeves.
[0015] 3. Beneficial effects
[0016] Compared with the prior art, the advantages of this invention are:
[0017] (1) The present invention utilizes the insertion design of the first to third magnetic blocks and the rod-shaped cylinders at both ends, so that the stable simulated splicing state can be maintained in various simulated operations, while the stability of each part and simulated block during transportation can be achieved without setting up an additional loading mechanism.
[0018] (2) The base of this design provides support for the octagonal support column. The chiseling of the fixing groove facilitates the insertion of the octagonal support column, and the chiseling of the motor groove facilitates the accommodation of the motor. The installation of the motor provides useful work for the lifting and lowering of the table. A lead screw is rotatably connected to the upper end of the motor. The lead screw transmits the useful work of the motor. The lead screw and the octagonal support column cooperate to convert the horizontal rotation force of the lead screw into vertical extension force, providing power for the lifting and lowering of the table. The setting of the lower limit pad helps to limit the lowering of the octagonal support column. A rubber sleeve is fixed to the upper end of the lower limit pad. The lower limit pad provides support for the four guide fixing blocks. The octagonal inner wall of the groove provides a fixing surface for four upper limit blocks, which in turn provide support for four guide fixing blocks. The four contact pressure blocks facilitate the cooperation with four upper contact pressure-sensitive switches and four guide fixing blocks to restrict the vertical movement of the octagonal frustum support column. The four guide fixing blocks facilitate the rotatable connection of the four blocks. The four guide pulley grooves provide a track for the vertical sliding of the four blocks and restrict their horizontal movement. The cooperation of the four guide pulley grooves guides and restricts the position of the octagonal frustum support column. The telescopic height of the octagonal frustum support column conforms to human mechanics, allowing for reasonable telescopic lifting based on the human body.
[0019] (3) The slots for accommodating the simulation board in this scheme are designed to facilitate the placement of the simulation board. Each set of devices is equipped with multiple simulation boards. The slots for multiple simulation blocks are cut into the simulation board to facilitate the insertion of multiple simulation blocks to achieve the simulation function. This facilitates the analysis and simulation of teaching problems in business administration majors and is in line with the case analysis simulation to enhance the teaching effect.

[0035] Specifically, please refer to the figure. The upper end of the table 8 has a simulation board receiving groove 9 and seven simulation block placement grooves 12. Simulation boards 10 are inserted between the inner walls of the simulation board receiving groove 9. The upper end of the simulation board 10 has evenly distributed simulation block slots 11.

[0036] In this embodiment, the opening of the simulation board receiving slot 9 facilitates the placement of the simulation board 10. Each set of devices is equipped with multiple simulation boards 10. The multiple simulation block slots 11 opened on the simulation board 10 are for the insertion of multiple simulation blocks 13 to realize the simulation function, which facilitates the analysis and simulation of teaching and learning questions in business administration majors, and conforms to the case analysis simulation to enhance the teaching effect.
[0037] Specifically, please refer to the figure. Each of the eight seats 5 has a handle 6 fixedly connected to its front end.
[0038] In this embodiment, the eight handles 6 are provided to facilitate pulling the seat support frame 4 and the seat 5 out from between the left and right inner walls of the hidden groove 3. The surfaces of the eight handles 6 are covered with rubber anti-slip sleeves to prevent the hands from slipping off.
[0039] Specifically, please refer to the figure. Each of the eight seats 5 has a sponge pad 7 fixedly connected to its upper end.
[0040] In this embodiment, the arrangement of eight sponge pads 7 makes it easier for a person to sit on the seat 5, increasing the comfort of the seat 5.
[0041] Specifically, please refer to the figure. Motor 27 is a three-phase asynchronous motor.
[0042] In this embodiment, the motor 27 is a three-phase asynchronous motor, and the forward and reverse rotation of the three-phase asynchronous motor facilitates the control of the up and down movement of the table 8.
[0043] Specifically, please refer to the figure. A control button 14 is fixedly connected to the upper end of the table 8.
[0044] In this embodiment, the control button 14 is used to control the start and stop of the motor 27.
[0045] Specifically, please refer to the figure. The surfaces of the upper limit block 20 and the lower limit pad 28 are fitted with rubber sleeves.
[0046] In this embodiment, the surfaces of the upper limit block 20 and the lower limit pad block 28 are covered with rubber sleeves, which serve as a buffer for the rise and fall of the octagonal frustum support column 15.
[0047] Working principle: Connect the device to the power supply, press the control button 14 to start the motor 27 to perform forward work, driving the lead screw 19 to rotate clockwise, causing the octagonal frustum support column 15 to move upward. During the upward movement of the octagonal frustum support column 15, the four guide pulleys 23 are guided upward within the guide rails of the four guide fixing blocks 24 respectively. When the four contact pressure blocks 22 touch the four upper contact pressure-sensitive switches 21, the motor 27 is automatically turned off, realizing the raising and lowering of the table 8. To lower it, press the control button 14 again to start the motor 27. 7. Reverse work is performed to move the octagonal frustum support column 15 downward. During the downward movement of the octagonal frustum support column 15, the four 23s are guided downward in the guide rails of the four guide fixing blocks 24 respectively. When the four contact pressure blocks 22 touch the four guide fixing blocks 25, the motor 27 is automatically turned off, realizing the lowering of the table 8. The table 8 can be raised and lowered. By holding the eight handles 6 respectively, the eight seats 5 hidden in the hidden slot 3 can be pulled out and sat on the sponge cushion 7. When not in use, holding the handles 6 respectively can hide and retract the eight seats 5.
[0048] Furthermore, before the entire device is transported to the display area or when it needs to be moved, each simulation block 13 is first placed into the placement slot 12. Then, the seat 5 is retracted into the hiding slot 3 using the handle 6. This causes the first magnetic block on the top of the seat 5 to attract the second magnetic block at the end of the simulation block 13, thus stably attaching the simulation block 13 to the placement slot 12. After the device is moved to the display area or after the relocation is completed, the handle 6 is pulled to make the seat 5 protrude out of the hiding slot 3 again. This causes the first magnetic block on the top of the seat 5 to detach from the second magnetic block at the end of the simulation block 13, allowing the simulation block 13 to be in a free and movable state. Then, the simulation blocks are spliced together according to the shape of the target simulated object. Multiple third magnetic blocks with switchable magnetic pole orientations are set between the simulation block slots 11 on the simulation board 10. By interchanged, the end orientation of the simulation blocks and the orientation of the third magnetic blocks can be changed, thus achieving any splicing state display during the simulation display process without the need for additional external fixing structures.
[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
