[0043] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. 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.

[0044] The first aspect of the embodiment of the present invention provides a practical training teaching method applied to intelligent warehousing technology, which mainly improves the learning and understanding of intelligent warehousing devices in intelligent warehousing technology, and deepens the understanding of the structure and operation of intelligent warehousing devices in combination with the various processing steps of intelligent warehousing devices, so as to achieve the purpose of improving the practical training teaching effect. The practical training teaching method applied to intelligent warehousing technology includes:

[0045] First, a physical model of the intelligent storage device to be used for practical teaching is made in a proportional manner, so as to improve the effect of practical teaching in a more intuitive way during the practical teaching process.

[0046] Second, make videos and / or pictures of each processing procedure of the intelligent storage device to be used for practical training and store them in a computer as courseware.

[0047] At this time, the computer is one of the components in the practical teaching method. First, the video and / or pictures of each processing process of the intelligent storage device to be trained are collected on site or videos or pictures simulating the processing process of each processing process are made and formed into courseware, and then stored in the computer. It can be opened for students to watch during the practical teaching process.

[0048] Third, the above-mentioned physical model includes an overall model of the intelligent storage device and a plurality of partial models formed by disassembling the physical model according to the processing procedures of the intelligent storage device.

[0049] At this time, the local model is formed by dividing the intelligent warehousing device into modules corresponding to each processing procedure according to the processing procedures of the intelligent warehousing device in the actual processing process, and then disassembling the other overall model according to the divided modules to form a local model.

[0050] Fourthly, a model calling device 1 is provided, and the model calling device 1 comprises a model storage unit 1.1 for storing the overall model and a plurality of local models respectively.

[0051] At this time, one of the multiple model storage units 1.1 is used to store the overall model, while the other model storage units 1.1 are used to store each local model. In this way, in the practical teaching process, for the intelligent storage device to be implemented, the overall model is used in conjunction with its video or / and picture, so that the college can first recognize and understand the intelligent storage device as a whole.

[0052] At the same time, by storing the local models in each model storage unit 1.1, when explaining the various parts of the intelligent storage device, the corresponding local models can be displayed to improve the effect of practical training teaching by combining entities with videos and / or pictures.

[0053] In addition, after adopting the model calling device 1, the overall model and each local model can be stored in each model storage unit 1.1 in advance. During the practical training teaching process, the overall model or the corresponding local model can be directly called for display using the model calling device 1.

[0054] Fifth, the models are stored in a number greater than the number to form a first serial number, and the courseware is numbered according to the number of the model storage unit 1.1 to form a second serial number corresponding to the state of the physical model in each model storage unit 1.1, and the model calling device 1 is used to display the physical model in the model storage unit 1.1 with the corresponding first serial number according to the second serial number of the courseware played on the computer.

[0055] At this time, the first serial number and the second serial number are set correspondingly, so that the model storage unit 1.1 where the physical model corresponding to the courseware selected for playing is located can be determined according to the second serial number of the courseware, and then the corresponding model storage unit 1.1 can be called by the model calling device 1 according to the courseware selected for playing, and the corresponding physical model can be displayed.

[0056] It should be noted that, in this embodiment, the purpose of numbering the model storage unit 1.1 and the courseware to form the first serial number and the second serial number respectively is to facilitate the selection of the corresponding entity model according to the courseware and to facilitate the display of the entity model using the model calling device 1.

[0057] After adopting the practical teaching method for intelligent warehousing technology according to the first aspect of the embodiment of the present invention, firstly, a physical model of the intelligent warehousing device to be trained is made in a proportional manner, and then a video and / or picture of the actual processing process of the intelligent warehousing device is made and stored in a computer as a courseware. In the process of practical teaching, the courseware of the intelligent warehousing device is played on the computer in combination with the physical model to improve the effect of practical teaching. In the process of practical teaching, the required physical model can be called by the model calling unit, which is more convenient for practical teaching.

[0058] Please refer to Figures 1 to 14 As shown, the second aspect of this embodiment provides a practical teaching platform for implementing the teaching method for intelligent warehousing technology, which mainly includes a box 2, a channel opening 3 and the above-mentioned computer and model calling device 1, wherein:

[0059] See also Figure 1 and Figure 2As shown, the box 2 serves as the shell part of the training teaching platform, which is arranged in a rectangular parallelepiped structure in this embodiment. The model mobilization device is arranged in the box 2, and the model storage unit 1.1 is also located in the box 2 in a hidden state. The computer is placed on the box 2, and the box 2 is provided with a channel opening 3 for the physical model to move from the inside of the box 2 to the outside of the box 2.

[0060] When the model calling device 1 is used to display the physical model of the specified first serial number, the model calling device 1 causes the physical model to move from the inside of the box 2 through the passage opening 3 to the top of the box 2 for display.

[0061] See also Figure 2 and Figure 3 As shown, the model calling device 1 also includes a suspension chain 1.2, a stepping motor 1.4 and an upper electric telescopic rod 1.5. Specifically:

[0062] There are two suspension chains 1.2 in the box 2, and the two suspension chains 1.2 are symmetrically distributed up and down. Figure 5 and Figure 6 As shown, sprockets 11 are provided at both ends of the two suspension chains 1.2, and the sprockets 11 are used to support the suspension chains 1.2 and drive the suspension chains 1.2 to rotate. A synchronization shaft 1.3 is provided between the sprockets 11 at the same side ends of the two suspension chains 1.2, and at this time, the synchronization shaft 1.3 is fixed to the two sprockets 11 at the same time.

[0063] See also Figure 4 and Figure 5 As shown, the stepper motor 1.4 provides power for the rotation of the suspension chain 1.2 by connecting with one of the synchronous shafts 1.3, and the stepper motor 1.4 is fixedly mounted on the inner wall of the box body 2.

[0064] See also Figure 2 , Figure 5 and Figure 7 As shown, a plurality of model storage units 1.1 are equidistantly arranged between two suspension chains 1.2, and there is always a model storage unit 1.1 located below the passage opening 3. In this way, a stepper motor 1.4 can be combined so that each time the stepper motor 1.4 rotates, the suspension chain 1.2 is driven to rotate once with the distance between two adjacent model storage units 1.1 as the stroke, and finally the model storage unit 1.1 below the passage opening 3 is replaced each time the stepper motor 1.4 moves.

[0065] See also Figure 1 and Figure 2 As shown, the electric telescopic lifting rod 1.5 is arranged in the box body 2 and is located directly below the passage opening 3. It is mainly used to lift the model storage unit 1.1 located directly above it after startup, so that the physical model in the lifted model storage unit 1.1 moves through the passage opening 3 to the outside of the box body 2 for display.

[0066] It should be noted that, in the embodiment of the practical teaching platform, buttons for controlling the stepping motor 1.4 and the upper electric telescopic rod 1.5 may be provided on the box body 2 to control the model calling device 1.

[0067] For further information, see Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the model storage unit 1.1 includes a guide rod 1.1.1, a guide sleeve 1.1.2, a placement box 1.1.3, a lifting plate 1.1.4 and an upward lifting drive component 1.1.5. The guide rod 1.1.1 is fixedly arranged between two suspension chains 1.2. In this embodiment, the guide rod 1.1.1 is arranged as a rectangular parallelepiped structure with square ends, and its two ends are respectively fixedly connected to the chain plates of the suspension chains 1.2 on the corresponding sides. After such arrangement, the guide rod 1.1.1 and the chain plates connected thereto can be kept relatively fixed, and the state of the model storage unit 1.1 can be stabilized by maintaining the state of the chain plates.

[0068] See also Figure 4 , Figure 5 , Figure 6 , Fig.12 and Fig.13 As shown, the guide sleeve 1.1.2 is slidably mounted on the outside of the guide rod 1.1.1, and the placement box 1.1.3 is fixedly mounted on the outside of the guide sleeve 1.1.2. The placement box 1.1.3 is lifted and lowered by the lifting and lowering movement of the guide sleeve 1.1.2 outside the guide rod 1.1.1, thereby realizing the lifting and lowering movement of the physical model placed in the placement box 1.1.3. When displaying a physical model of a first serial number, the upper electric telescopic rod 1.5 directly lifts the bottom of the placement box 1.1.3, so that the placement box 1.1.3 carrying the physical model moves toward the passage opening 3.

[0069] See also Figure 2 , Figure 5 and Figure 7 As shown, the lifting plate 1.1.4 is arranged in the placing box 1.1.3, and the four side surfaces of the lifting plate 1.1.4 are slidably matched with the four side inner walls of the placing box 1.1.3. Specifically, in this embodiment, the sliding match between the lifting plate 1.1.4 and the inner wall of the placing box 1.1.3 is achieved by the lifting plate 1.1.4 contacting the side inner wall of the placing box 1.1.3. In this way, the placing box 1.1.3 can stabilize the state of the lifting plate 1.1.4 and prevent the lifting plate 1.1.4 from tilting, especially when the lifting plate 1.1.4 is lifted and lowered in the placing box 1.1.3, the placing box 1.1.3 guides and limits the lifting plate 1.1.4 to keep the stability of the physical model on the lifting plate 1.1.4.

[0070] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figures 10 to 14 As shown, the lifting drive component 1.1.5 is arranged between the lifting plate 1.1.4 and the guide rod 1.1.1, and the lifting drive component 1.1.5 is configured to make the lifting plate 1.1.4 slide upward to the channel opening 3 in the placement box 1.1.3 when the guide sleeve 1.1.2 moves to the highest position on the guide rod 1.1.1, and the top end of the placement box 1.1.3 contacts the inner top wall of the box body 2.

[0071] At this time, in this embodiment, when the placement box 1.1.3 moves upward, the lifting plate 1.1.4 is driven by the lifting driving component 1.1.5 in the placement box 1.1.3 to move toward the top of the placement box 1.1.3. The guide sleeve 1.1.2 has a highest position and a lowest position on the guide rod 1.1.1. Figure 12 to Figure 14 As shown, the highest position corresponds to the position of the guide sleeve 1.1.2 on the guide rod 1.1.1 when the physical model is displayed outside the box 2, see Figure 4 , Figure 5 and Figure 7 As shown, the lowest position corresponds to the position where the guide sleeve 1.1.2 is located on the guide rod 1.1.1 when the placement box 1.1.3 is in the initial state and is not pushed up by the electric telescopic rod 1.5.

[0072] Also, see Figure 1 and Figure 2 As shown, before the top of the placement box 1.1.3 contacts the inner top wall of the box body 2, the lifting plate 1.1.4 enters the passage opening 3, and after the top of the placement box 1.1.3 contacts the inner top wall of the box body 2, the top of the lifting plate 1.1.4 is flush with the top of the box body 2.

[0073] Such arrangement enables the combination of the placement box 1.1.3 and the passage opening 3 to achieve stable guiding and limiting effects on the lifting plate 1.1.4, specifically, before the lifting plate 1.1.4 leaves the top opening of the placement box 1.1.3, its top end has entered the passage opening 3; conversely, before the lifting plate 1.1.4 leaves the passage opening 3, its bottom end has entered the placement box 1.1.3.

[0074] During this process, the cooperation between the placement box 1.1.3 and the channel opening 3 can always ensure the stability of the lifting plate 1.1.4 when the lifting plate 1.1.4 moves between the placement box 1.1.3 and the channel opening 3, thereby keeping the lifting plate 1.1.4 in a stable state during the entire lifting and displacement process.

[0075] For further information, see Figure 12 to Figure 14As shown, the lifting driving component 1.1.5 includes a support plate 1.1.5a, a screw sleeve 1.1.5b, a screw rod 1.1.5c, a rack 1.1.5d, a rack gear 1.1.5e and a transmission structure 1.1.5f.

[0076] The support plates 1.1.5a are arranged on both sides of the bottom of the upper platform, and the support plates 1.1.5a on both sides of the bottom of the lifting plate 1.1.4 are arranged relative to each other. Specifically, the support plates 1.1.5a are located between the inner bottom wall of the placement box 1.1.3 and the bottom of the lifting plate 1.1.4. The screw rod 1.1.5c is rotatably mounted on the inner bottom wall of the placement box 1.1.3, and the screw sleeve 1.1.5b is in a state of being threadedly sleeved on the screw rod 1.1.5c, and one screw sleeve 1.1.5b is arranged corresponding to the support plates 1.1.5a on both sides of the lifting plate 1.1.4, and the outer end of the support plate 1.1.5a is rotatably connected to the first connecting rod, and the screw sleeve 1.1.5b is fixedly arranged on the first connecting rod.

[0077] Specifically, the screw sleeves 1.1.5b on both sides below the lifting plate 1.1.4 are threadedly connected to the outside of the screw rod 1.1.5c. When the screw rod 1.1.5c rotates, the two screw sleeves 1.1.5b are driven to move relative to or away from each other. At this time, the screw sleeves 1.1.5b drive the outer ends of the lifting plate 1.1.4 to move relative to or away from each other. The inner end of the support plate 1.1.5a is rotatably connected to the bottom of the lifting plate 1.1.4. When the two screw sleeves 1.1.5b move relative to each other, the outer ends of the two support plates 1.1.5a move relative to each other. At this time, the inner end of the support plate 1.1.5a props up the lifting plate 1.1.4 so that the lifting plate 1.1.4 moves upward in the placement box 1.1.3. On the contrary, when the outer ends of the support plates 1.1.5a move away from each other, the inner ends of the support plates 1.1.5a will support the lifting plate 1.1.4 to move downward in the placement box 1.1.3.

[0078] The rack 1.1.5d is arranged on the surface of the guide rod 1.1.1, specifically, the rack 1.1.5d is arranged on the side surface of the guide rod 1.1.1 facing the placement box 1.1.3, and the rack 1.1.5d is arranged parallel to the length direction of the guide rod 1.1.1. The track gear 1.1.5e is rotatably mounted on the guide sleeve 1.1.2, and the track gear 1.1.5e is meshed with the rack 1.1.5d. When the guide sleeve 1.1.2 is lifted and displaced on the guide rod 1.1.1, the track gear 1.1.5e rolls on the rack 1.1.5d.

[0079] The transmission structure 1.1.5f is arranged between the track gear 1.1.5e and the screw 1.1.5c, and is used to drive the screw 1.1.5c to rotate when the track gear 1.1.5e rolls on the rack 1.1.5d. Specifically, when the guide sleeve 1.1.2 moves upward on the guide rod 1.1.1, the track gear 1.1.5e drives the screw 1.1.5c to rotate through the transmission structure 1.1.5f, and then uses the screw 1.1.5c to drive the screw sleeve 1.1.5b and the support plate 1.1.5a to move, and finally the lifting plate 1.1.4 moves upward in the placement box 1.1.3. On the contrary, when the guide sleeve 1.1.2 moves downward on the guide rod 1.1.1, the rail gear 1.1.5e drives the screw 1.1.5c to rotate through the transmission structure 1.1.5f, and then uses the screw 1.1.5c to drive the screw sleeve 1.1.5b and the support plate 1.1.5a to move, and finally the lifting plate 1.1.4 moves downward in the placement box 1.1.3 and recovers.

[0080] At this time, in this embodiment, the transmission structure 1.1.5f includes a transmission belt and a transmission gear set. One end of the transmission belt is connected to the rail gear 1.1.5e. When the rail gear 1.1.5e rolls, it drives the transmission belt to rotate. The other end of the transmission belt is rotatably installed on the inner bottom wall of the placement box 1.1.3. The transmission gear set is connected between the other end of the transmission belt and the screw 1.1.5c. When the transmission belt rotates, the screw 1.1.5c is driven to rotate through the transmission gear set.

[0081] Furthermore, in this embodiment, a pair of racks 1.1.5d, a pair of track gears 1.1.5e and a transmission gear set are provided, and the pair of racks 1.1.5d are symmetrically arranged on both sides of the surface of the guide rod 1.1.1, and the pair of track gears 1.1.5e are rotatably mounted on both sides of the inside of the guide sleeve 1.1.2. At this time, grooves are provided on both sides of the surface of the guide rod 1.1.1, and the pair of racks 1.1.5d are fixedly mounted in the grooves, and a through groove is provided in the middle of one side of the guide sleeve 1.1.2 facing the placement box 1.1.3, and a pair of track gears 1.1.5e are rotatably mounted on the inner walls of both sides of the through groove, and the pair of track gears 1.1.5e are connected by a gear shaft, and one end of the transmission belt is mounted on the gear shaft.

[0082] The transmission gear set includes two meshing circular gears, one of which is fixed on the screw 1.1.5c, and the other circular gear is rotatably mounted on the inner bottom wall of the placement box 1.1.3 through the gear shaft, and the other end of the transmission belt is mounted on the gear shaft of the circular gear between the two circular gears.

[0083] For further information, see Figure 3 , Figure 8 and Fig.11As shown, the end of the guide rod 1.1.1 is fixed to the middle part of one of the chain plates of the suspension chain. At this time, the chain shafts 1.2.1 at both ends of the chain plate connecting the guide rod 1.1.1 are symmetrically distributed on both sides of the guide rod 1.1.1. And the chain plate is provided with suspension wheels 4 on both sides of the ends of the guide rod 1.1.1. Specifically, the suspension wheels 4 are located on the opposite sides of the two suspension chains 1.2, and are symmetrically distributed on both sides of the ends of the guide rod 1.1.1 in the rotation direction of the suspension chain 1.2, and the two suspension wheels 4 corresponding to the same guide rod 1.1.1 are provided at both ends of the chain plate connected to the end of the guide rod 1.1.1. At this time, two suspension wheels 4 of this embodiment are provided on the suspension chain 1.2 corresponding to the ends of each guide rod 1.1.1.

[0084] See also Figure 4 , Figure 5 and Fig. 9 As shown, a suspension track 5 fixedly installed in the box body 2 is provided on the outer side of the suspension chain 1.2. Two suspension tracks 5 are provided, and the two suspension tracks 5 are arranged opposite to each other up and down, and the two suspension chains 1.2 are located between the two suspension tracks 5. The suspension track 5 is arranged to match the shape of the suspension chain 1.2. A track cavity is provided inside the suspension track 5, and closed-loop track openings 6 are provided on opposite sides of the two suspension tracks 5. The suspension wheel 4 is located in the suspension track 5 and can roll in the track cavity. The wheel axle of the suspension wheel 4 passes through the track opening 6 and is connected to the suspension chain 1.2. The wheel axle is arranged in a state parallel to the axial direction of the sprocket 11.

[0085] At this time, the two suspension chains 1.2 are connected by the guide rod 1.1.1, and the suspension wheels 4 on the two suspension chains 1.2 cooperate with the suspension track 5, so that the overall stability of the suspension chain 1.2 is strong. At the same time, the suspension chain 1.2 is set in a vertical state, and the suspension chain 1.2 itself also has strong stability in this state. For each model storage unit 1.1, after the above setting, a pair of suspension wheels 4 are set on both sides of the end of each guide rod 1.1.1. At this time, the suspension wheels 4 cooperate with the suspension track 5, and the suspension wheels 4 are located at both ends of the same chain plate, which can further improve the stability of the model storage unit 1.1 and also make the guide rod 1.1.1 have extremely strong stability. When any model storage unit 1.1 moves to the position directly below the passage opening 3, the guide rod 1.1.1 is stably maintained in a vertical state, which has a stable guiding effect on the placement box 1.1.3, so that the lifting plate 1.1.4 can accurately enter the passage opening 3.

[0086] For further information, see Figure 4 , Figure 6 and Figure 8As shown, a calibration rod 7 is provided on the box body 2. Specifically, the suspension track 5 is fixedly provided on a bracket 10, and the bracket 10 is fixedly connected to the inner wall of the box body 2. The calibration rod 7 is fixed to the box body 2 by being installed on the bracket 10. The calibration rod 7 includes an elastic rod body 7.1, an intermediate rod body 7.2 and a side rod body 7.3.

[0087] See also Fig.12 and Fig.13 As shown, the elastic rod body 7.1 includes a rod sleeve and an inner rod which are nested with each other. One end of the inner rod is inserted into the rod sleeve and can be axially displaced in the rod sleeve. A rod spring is arranged between the end of the inner rod inserted into the rod sleeve and the inner wall of the end of the rod sleeve.

[0088] See also Fig.12 and Fig.13 As shown, the middle rod body 7.2 is vertically fixed on the extended end of the elastic rod body 7.1, the extended end of the elastic rod body 7.1 refers to the end of the inner rod located outside the rod sleeve, and the middle rod body 7.2 is parallel to the straight part of the suspension chain 1.2. Two side rod bodies 7.3 are provided, and the two side rod bodies 7.3 are respectively fixed at the two ends of the middle rod body 7.2, and the two side rod bodies 7.3 are distributed in an "eight" state, so that the distance between the side rod bodies 7.3 is smaller as they are closer to the middle rod body 7.2.

[0089] The middle rod 7.2 coincides with the center line of the passage opening 3 in the straight part of the suspension chain 1.2. At this time, the two side rods 7.3 are symmetrically distributed on both sides of the center line of the passage opening 3 in the straight part of the suspension chain 1.2.

[0090] See also Fig.12 and Fig.13 As shown, a pressure rod 8 is fixedly provided on the inner side surface of the guide sleeve 1.1.2, and before the placement box 1.1.3 moves upward to contact the inner top wall of the box body 2, the pressure rod 8 drives the calibration rod 7 to move, so that the two side rod bodies 7.3 are inserted into the chain link gaps on both sides of the top of the guide rod 1.1.1 located directly below the channel opening 3 and squeeze the chain shaft 1.2.1 to calibrate the lifting plate 1.1.4 and the channel opening 3.

[0091] Specifically, when the model storage unit 1.1 is located directly below the passage opening 3, when the lifting plate 1.1.4 is in an alignment state with the passage opening 3, the guide rod 1.1.1 is located in the middle position of the passage opening 3 in the direction of the straight portion of the suspension chain 1.2.

[0092] During the upward displacement of the guide sleeve 1.1.2 on the guide rod 1.1.1, the pressure rod 8 will move synchronously with the guide sleeve 1.1.2. Before the top of the placement box 1.1.3 contacts the inner top wall of the box body 2, the pressure rod 8 drives the calibration rod 7 to move. During the displacement process, the calibration rod 7 makes the side rod bodies 7.3 on both sides of it insert into the symmetrically distributed chain link gaps on both sides of the end of the guide rod 1.1.1, and squeeze the chain shaft 1.2.1. During the extrusion process, since the two side rod bodies 7.3 are distributed in an "eight" shape, the two side rod bodies 7.3 are continuously inserted into the chain link gaps. By squeezing the chain shaft 1.2.1 inward, it can ensure that the chain link directly connected to the guide rod 1.1.1 is stable in the state of the chain link when the lifting plate 1.1.4 is aligned with the channel opening 3, thereby achieving the purpose of calibration.

[0093] Furthermore, since the track opening 6 is arranged to be compatible with the wheel axle, when the side rod body 7.3 squeezes the chain shaft 1.2.1, the side rod body 7.3 can cooperate with the side wall of the track opening 6 to clamp the chain link directly connected to the guide rod 1.1.1, so as to improve the stability of the chain link and achieve the purpose of improving the stability of the model storage unit 1.1 of the model being exhibited.

[0094] Specifically, see Figure 4 As shown, the pressure rod 8 includes a transverse portion 8.1 arranged parallel to the elastic rod body 7.1, a vertical portion 8.2 extending vertically upward from one end of the transverse portion 8.1 away from the guide sleeve 1.1.2, and a guide portion 8.3 extending obliquely upward from the top of the vertical portion 8.2 to the side away from the guide sleeve 1.1.2.

[0095] A pressing wheel 9 is arranged on the elastic rod 7.1, and before the placement box 1.1.3 moves upward to contact the inner top wall of the box body 2, the pressing rod 8 drives the pressing wheel 9 to move from the guide part 8.3 to the vertical part 8.2.

[0096] At this time, during the upward movement of the guide sleeve 1.1.2, the guide portion 8.3 of the pressure rod 8 first contacts the pressure wheel 9, and the top of the placement box 1.1.3 does not contact the inner top wall of the box body 2, and the guide sleeve 1.1.2 continues to move upward. During this process, the pressure rod 8 causes the pressure wheel 9 to move from the guide portion 8.3 to the vertical portion 8.2, and when the pressure wheel 9 moves to the vertical portion 8.2, the side rod body 7.3 on the calibration rod 7 cooperates with the suspension track 5 to firmly fix the chain link connecting the guide rod 1.1.1. During the subsequent upward movement of the guide sleeve 1.1.2, the pressure wheel 9 continues to move in the vertical portion 8.2, so that the lifting plate 1.1.4 and the channel opening 3 are in a stable alignment state.

[0097] The pressing wheel 9 is arranged on the middle rod 7.2. At this time, the rod sleeve of the elastic rod 7.1 is fixedly mounted on the bracket 10, and a pair of elastic rods 7.1 are arranged on the middle rod 7.2 and symmetrically distributed at both ends of the middle rod 7.2, and the pressing wheel 9 is located between the two elastic rods 7.1.

[0098] Specifically, the rod spring in the elastic rod body 7 . 1 restores the calibration rod 7 to its initial state when the pressure rod 8 moves downward and disengages from the pressure wheel 9 .

[0099] In summary, the teaching platform provided by this embodiment combines the video or picture played in the computer with the entity display to improve the effect of practical teaching. And the switching between different entity models can be achieved by controlling the stepper motor 1.4 to switch the different model storage units 1.1 to move to the bottom of the passage 3, and then start the upper electric telescopic rod 1.5 to push the placement box 1.1.3 up to the top wall of the box 2. In this process, the lifting drive component 1.1.5 makes the lifting plate 1.1.4 move from the placement box 1.1.3 to the passage 3, so that the entity model placed on the lifting plate 1.1.4 is displayed on the top of the box 2.
