DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1 - Figure 6 As shown, a training demonstration model based on human resource management includes a display board 1, a connecting seat 2 is arranged at the bottom end of the rear part of the display board 1, a first hinged seat 3 is fixedly connected to the front part of the connecting seat 2, the first hinged seat 3 is hinged to one end of a first rotating rod 4, the other end of the first rotating rod 4 is fixedly connected to the rear part of the display board 1, a moving mechanism is arranged at the top of the display board 1, the moving mechanism includes a moving groove 5, the moving groove 5 is opened at the top of the connecting seat 2, the two ends of the moving groove 5 are rotatably connected to the screw rod 6, the outer side of the screw rod 6 is threadedly connected to the moving block 7, the rear part of the connecting seat 2 is fixedly connected to the motor 8, and the output shaft of the motor 8 passes through the connecting seat 2 and is fixedly connected to one end of the screw 6;

[0027] When working, the motor 8 will drive the screw 6 to rotate, thereby driving the moving block 7 and the second hinge seat 9 to move. In cooperation with the moving mechanism, the display board 1 will rotate with the first rotating rod 4 fixedly connected at the rear bottom end and the hinged point of the first hinge seat 3 as the center of the circle, so as to adjust the angle of the display board 1. This solves the problem that the angle and height of the display board 1 cannot be adjusted when the display board 1 is currently used for training and teaching of human resource management. The fixed angle and height of the display board 1 are not convenient for teachers of different heights to teach, and it also cannot provide students in the classroom with the best viewing position, thereby reducing the efficiency of teaching and training.

[0028] Further, such as Figure 2 and Figure 3 As shown, the top of the moving block 7 is fixedly connected with a second hinge seat 9, and the second hinge seat 9 is hinged to one end of a second rotating rod 10, and the other end of the second rotating rod 10 is hinged to a third hinge seat 11, and the third hinge seat 11 is fixedly connected to the rear of the display board 1;

[0029] During operation, the movement of the moving block 7 and the second hinge seat 9 can cooperate with the third hinge seat 11 to realize the rotation of the rotating rod, and then realize the rotation of the display board 1, so as to adjust the angle of the display board 1.

[0030] Further, such as Figure 3 As shown, the moving block 7 is inside the moving groove 5, and the size of the moving block 7 is adapted to the moving groove 5;

[0031] During operation, the rotation of the screw 6 will cause the moving block 7 to have the same tendency to rotate. Since the size of the moving block 7 is adapted to the moving groove 5, the tendency of the moving block 7 to rotate will be hindered by the lifting groove. Due to the characteristics of the threaded connection between the moving block 7 and the screw 6, the moving block 7 can move on the screw 6 as the screw 6 rotates.

[0032] Further, such as Figure 1 As shown, the bottom end of the connecting seat 2 is fixedly connected to the top end of the electric telescopic rod 12, and the bottom end of the electric telescopic rod 12 is fixedly connected to the base 13;

[0033] During operation, the lifting and lowering of the electric telescopic rod 12 can change the height of the display board 1, so as to adjust it to a suitable height, and the base 13 is used to place a ground support device.

[0034] Further, such as Figure 1 and Figure 4 As shown, a slide groove 14 is provided at the top and bottom of the display board 1, a sliding mechanism is provided inside the slide groove 14, and the sliding mechanism includes a long rod 15, two ends of the long rod 15 are fixedly connected to the two ends inside the slide groove 14, and a slider 16 is sleeved on the outside of the long rod 15. A cleaning plate 17 is provided at the front of the display board 1, and the top and bottom ends of the cleaning plate 17 are fixedly connected to the slider 16;

[0035] During work, when the display board 1 needs to be cleaned, the teacher only needs to hold the cleaning board 17 and move it toward the other end of the display board 1 to clean the display board 1.

[0036] Further, such as Figure 4 As shown, a spring 18 is sleeved on the outside of the long rod 15, and both ends of the spring 18 are fixedly connected to the slider 16 and one end of the slide slot 14;

[0037] During operation, the elastic force of the spring 18 keeps the slider 16 and the cleaning plate 17 at one end of the display board 1 at all times, which does not affect the normal display of the display board 1. At the same time, after the staff slides the cleaning plate 17 to clean the display board 1, the elastic force of the spring 18 resets the cleaning plate 17.

[0038] Further, such as Figure 5 As shown, the four corners of the bottom end of the base 13 are fixedly connected with universal wheel assemblies 18, the bottom end of the base 13 is provided with two groups of lifting grooves 19, the two ends of the lifting grooves 19 are rotatably connected with threaded rods 20, the outer sides of the two ends of the threaded rods 20 are threadedly connected with lifting blocks 21, the bottom end of the lifting block 21 is fixedly connected with two groups of first connecting blocks 22, the first connecting block 22 is hinged to one end of the lifting rod 23, the other end of the lifting rod 23 is hinged to two groups of second connecting blocks 24, the bottom end of the second connecting block 24 is fixedly connected to the lifting plate 25, the outer side of the middle part of the threaded rod 20 is fixedly connected with a limiting column 26, and the threads opened at the two ends of the threaded rod 20 are opposite;

[0039] During operation, the base 13 can be moved by the universal wheel assembly 18, so as to be moved to a position suitable for teaching. After moving, in order to prevent the base 13 from moving, it is necessary to turn on the electric motor 30 to drive the two sets of threaded rods 20 to rotate, so as to cooperate with the opposite threads opened at both ends of the threaded rods 20 to realize the relative movement of the two sets of lifting blocks 21 and the first connecting block 22, and then cooperate with the rotation of the second connecting block 24 and the lifting rod 23 to realize the touching of the lifting plate 25, and suspend the universal wheel assembly 18 in the air, so that the lifting plate 25 supports the entire device, and will not slide due to the universal wheel assembly 18. The limiting column 26 can limit the moving position of the first connecting block 22 to prevent the first moving block 7 from moving to be aligned with the second moving block 7 up and down. This will make the base 13, the lifting rod 23 and the lifting plate 25 form a parallelogram, which is not stable. Otherwise, the three are always in a trapezoid and are stable.

[0040] Further, such as Figure 6 As shown, two groups of rotating columns 27 are provided on one side of the base 13, and the output shaft of the rotating column 27 passes through the base 13 and is fixedly connected to one end of the two groups of threaded rods 20, a transmission belt 28 is sleeved on the outer side of the rotating column 27, the transmission belt 28 is meshed with the rotating column 27, a protective shell 29 is provided on the outer side of the transmission belt 28, and the protective shell 29 is fixedly connected to one side of the base 13, an electric motor 30 is provided at one end of the protective shell 29, and the output shaft of the electric motor 30 passes through the protective shell 29 and is fixedly connected to one group of rotating columns 27;

[0041] During operation, since the stable lifting of the lifting plate 25 requires the two groups of threaded rods 20 to rotate in the same direction and speed at the same time, two groups of motors 8 are originally required to control the rotation of the two groups of screw rods 6 respectively. In order to prevent errors and the high production cost of setting up multiple groups of electric motors 30, two groups of rotating columns 27 are used to be fixedly connected with the two groups of threaded rods 20, and the same transmission belt 28 is used to be sleeved on the outside of the two groups of rotating columns 27. In this way, only one group of threaded rods 20 is needed to control the rotation of the two groups of rotating columns 27 and the threaded rods 20 at the same time, and the engagement of the transmission belt 28 with the rotating column 27 is to prevent the transmission belt 28 from slipping on the rotating column 27.

[0042] Working principle: the base 13 can be moved by the universal wheel assembly 18 to a position suitable for teaching. After moving, in order to prevent the base 13 from moving, it is necessary to turn on the electric motor 30 to drive the two sets of threaded rods 20 to rotate, so as to cooperate with the opposite threads opened at both ends of the threaded rods 20 to realize the relative movement of the two sets of lifting blocks 21 and the first connecting block 22, and then cooperate with the rotation of the second connecting block 24 and the lifting rod 23 to realize the touching of the lifting plate 25, and suspend the universal wheel assembly 18 in the air, so that the lifting plate 25 supports the entire device, and will not slide due to the universal wheel assembly 18. The height of the display board 1 can be adjusted by turning on the electric telescopic rod 12, and the screw rod 6 can be driven to rotate by turning on the motor 8. Thereby, the moving block 7 and the second hinge seat 9 are driven to move, and then the second rotating rod 10 is realized to rotate in cooperation with the third hinge seat 11, so that the display board 1 can rotate with the first rotating rod 4 fixedly connected at the rear bottom end and the hinged point of the first hinge seat 3 as the center, so as to adjust the angle of the display board 1. When the display board 1 needs to be cleaned, the teacher only needs to hold the cleaning board 17 and move it to the other end of the display board 1 to scrub the display board 1, and the elastic force of the spring 18 makes the slider 16 and the cleaning board 17 always at one end of the display board 1, which will not affect the normal display of the display board 1. At the same time, after the staff slides the cleaning board 17 to clean the display board 1, the elastic force of the spring 18 resets the cleaning board 17.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
