Description

Technical Field

[0001] The utility model relates to a cross-disciplinary practical training teaching demonstration device, belonging to the field of teaching demonstration. Background Art

[0002] The virtual business social environment VBSE divides the panoramic simulation of the enterprise's business management into two parts: the enterprise entity and the external service agency. The main enterprise is a number of manufacturing companies in the same industry. Under the same market economic environment, these manufacturing companies operate their enterprises according to their own business policies. The decisions they make in the course of operation are ultimately reflected in the differences in their respective business performance. Each main enterprise is a competitor. The VBSE virtual business social environment is a practical teaching method. It builds a virtual business social environment on campus, simulates the real scenes in the enterprise, sets up the functional departments, positions, processes, systems, and cases of the enterprise's operations, and simulates a large number of currencies, products, account books, business licenses, official seals, etc. During use, it strictly abides by the relevant regulations of the enterprise, enabling students to choose their jobs independently and experience the real corporate working environment, thereby improving students' learning interest and professional skills, and laying the foundation for actual operations in the future.

[0003] These courses often only explain abstract theoretical knowledge, which makes the teaching content difficult to understand and boring, unable to mobilize students' enthusiasm for learning, and students' attention is easily distracted, thus affecting the quality of teaching. Therefore, practical teaching demonstration devices are needed to cooperate with teaching. However, the existing practical teaching demonstration devices need to rely on manpower for moving. Since the practical teaching demonstration devices for computer applications are large in size and heavy in weight, it is very difficult to carry them. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-2 The utility model provides a technical solution: a cross-disciplinary practical training teaching demonstration device, comprising a demonstration box 1 with a roller 23 and a base 4, the demonstration box 1 having a setting space 2 inside, the top surface of the demonstration box 1 is provided with an open groove 3 communicating with the inside of the setting space 2, a display screen 5 is fixed on the top of the base 4, a lifting component is provided inside the setting space 2, a moving component is connected to the lifting component, a shielding plate 12 blocking the opening groove 3 is provided on the moving component, the lifting component comprises a driving motor 6 arranged inside the setting space 2, a screw rod 7 is connected to the output end of the driving motor 6, a threaded seat 8 is threadedly sleeved on the screw rod 7, an L-shaped plate 9 is fixedly provided on the back of the threaded seat 8, and the top of the L-shaped plate 9 is fixedly connected to the bottom end of the base 4.

[0023] See also Figure 2 A bearing 10 is sleeved on the top of the screw rod 7, a support rod 11 is fixed on the outer wall of the bearing 10, and the other end of the support rod 11 is fixed on the inner wall of the setting space 2. The design of the bearing 10 ensures the rotation stability of the designed screw rod.

[0024] See also Figure 2A fixing plate 20 is fixed on the outer wall of the bearing 10, and a traction rod 21 that slides through the threaded seat 8 is fixed between the fixing plate 20 and the outer shell of the driving motor 6. The designed traction rod 21 can ensure the normal lifting and lowering movement of the threaded seat 8 on the screw rod 7.

[0025] See also Figure 2 and Figure 4 A bevel gear 13 is fixedly provided at the top of the screw rod 7, and the moving assembly includes a secondary bevel gear 14 meshing with the bevel gear 13. A secondary screw rod 15 is fixedly penetrated through the central axis of the secondary bevel gear 14, and a secondary threaded seat 16 is threadedly sleeved on the secondary screw rod 15. A secondary L-shaped plate 17 is fixedly provided on the side of the secondary threaded seat 16. The other end of the secondary L-shaped plate 17 is fixedly connected to the bottom end of the baffle plate 12. A slide groove 24 is provided on the top surface of the demonstration box 1 for the secondary L-shaped plate 17 to slide through. Both ends of the secondary screw rod 15 are sleeved with secondary bearings 18, and the secondary bearings 18 are fixed on the inner wall of the setting space 2, and a transverse secondary traction rod 19 that slides through the secondary threaded seat 16 is fixed in the setting space 2.

[0026] Turn on the driving motor 6 to drive the designed screw 7 to rotate, thereby driving the designed threaded seat 8 to rise and fall on the screw 7, and in the process of the screw 7 rotating, the bevel gear 13, the secondary bevel gear 14 and the secondary screw 15 are driven to rotate, thereby driving the secondary threaded seat 16 to move forward on the secondary screw, thereby driving the shielding plate 12 to move forward. At this time, the shielding plate 12 does not block the opening slot 3, so it can ensure that the display screen 5 can normally pass through the opening slot 3, and as the shielding plate 12 moves forward, the demonstration box 1 is added with the shielding plate 12, and its surface area is increased, thereby increasing the teaching area, and some teaching supplies can be placed on the surface of the shielding plate 12, thereby improving its practical effect.

[0027] On the contrary, the display screen 5 is slowly stored into the setting space 2 , and then the shielding plate 12 shields the opening groove 3 to store and protect the display screen 5 .

[0028] See also Figure 1 The demonstration box 1 is provided with a plurality of drawers 22, and the rollers 23 are provided with brake pads. The teaching supplies to be used can be stored in the drawers 22, and the designed rollers 23 ensure that the entire device can be moved, avoiding the need to rely on manpower for carrying during movement, which brings difficulty to the transportation.

[0029] During specific operation, the driving motor 6 is turned on to drive the designed screw rod 7 to rotate, thereby driving the designed threaded seat 8 to rise and fall on the screw rod 7, and the base 4 and the threaded seat 8 are connected by an L-shaped plate 9, which can finally directly drive the display screen on the base 4 to rise and fall.

[0030] Therefore, the present application utilizes the designed lifting assembly to store the display screen 5 used in the teaching demonstration into the setting space 2 in the demonstration box 1, so that the display screen 5 is protected when not in use, and can effectively prevent foreign objects from colliding with the display screen 5 when not in use, causing collision damage to the display screen 5.
