At the same time, the front and rear ends of the display board 3 are arranged in an arc shape, and a foldable or retractable covering cloth is provided near the center of the display board 3. The display board 3 is rotated and erected to obtain support from the cylinder and the internal components can be covered by the covering cloth. After being supported, it can be rotated by the support frame 2 and the telescopic rod 4, and the position of the display board 3 can also be changed. If each display board 3 plays cases of different scene states, the states of the erected display board 3 can still be rotated to explain one by one. At the same time, the closing member 5 is made of a soft material to ensure that the display board 3 is rotated to compress it without hindering the rotation of the display board 3.

[0018] The control assembly includes a plurality of support members 28 fixed to the closing member 5, and the support members 28 are arranged opposite to each expansion board 7, a moving block 29 is slidably connected to the support member 28, a motor 2 30 is fixedly arranged on the moving block 29, a slide rail 31 is arranged on the support member 28, and rollers 32 embedded in the slide rail 31 are respectively clamped on the motor 2 30, a connecting rod 33 is arranged between the roller 32 and the bottom of the expansion board 7, one end of the connecting rod 33 is rotatably connected to the roller 32, and the other end is rotatably connected to the expansion board 7, a transmission wheel 1 34 is rotatably connected to the rotating shaft of the motor 2 30, a rotating wheel 35 meshing with the transmission wheel 1 34 is arranged at the end of the slide rail 31, and a driving rotating wheel 35 is arranged in the closing member 5 to rotate. The motor 36 is driven, and one end of the connecting rod 33 located at the roller 32 is clamped with the transmission wheel 1 34. The side of the display board 3 close to the center is set in an arc shape. The end of the slide rail 31 is provided with a sensor for sensing the transmission wheel 1 34. The motor 36 is provided with a controller for receiving the sensor signal. The control console 11 is provided with a switch 37 for controlling the motor 2 30 to turn on. When the expansion board 7 needs to be flush with the display board 3, the motor 2 30 is driven to drive the roller 32 to move along the slide rail 31. The lower moving block 29 is set to be driven by the roller 32 to move like a car wheel. After the roller 32 is driven to move, the connecting rod 33 connected to the rotation is driven to move together, so that the expansion board 7 is driven to move. The roller 32 moves along the bottom of the display board 3 to the center of the entire closure 5, and waits for the roller 32 to move to the bottom, and then moves with the connecting rod 33 connected to the roller 32, and pulls the expansion board 7 to move synchronously and staggered with the display board 3 through the connecting rod 33. After the roller 32 moves along the slide rail 31 and moves to the end of the slide rail 31, the transmission wheel 1 34 will be engaged with the rotating wheel 35 set at the end of the slide rail 31, and the rotating wheel 35 and the roller are staggered. The sensor senses the transmission wheel 1 34 and then outputs a signal to the controller to drive the motor 36, and controls the motor 36 to start and drive the rotating wheel 35 to rotate and drive the meshing transmission wheel 1 34 to rotate, and the transmission wheel 1 34 rotates At the same time, the connecting rod 33 is driven to rotate upward, so as to push the expansion board 7 up and be flush with the display board 3. At the same time, the motor three 36 drives the transmission wheel one 34 to finally rotate to make the expansion board 7 fit with the display board 3, so as to ensure that the display board 3 and the expansion board 7 are connected flush with each other, and the overall display area is expanded to increase its display effect. The driving method of the motor three 36 is also the existing technology. The angle of its driving rotation can be set in advance through the program, such as the servo motor type, which can be realized, so no further discussion is made. The display board 3 and the expansion board 7 are spliced ​​and synchronously play a whole picture, or play different pictures separately. This can also be set in advance through the program, which is all existing technology.After the above arrangement, if you are introducing or demonstrating to multiple people, and you are afraid that the distance is too far, you can splice the display board 3 with the expansion board 7, and splice the same screen images to achieve the playback effect, so that the large-screen playback effect is convenient for a group of people to explain, etc. A single fixed display is continuously played, so the overall splicing is larger and more intuitive. If you encounter an inspection or the number of people is not too large but it is not a single explanation, the middle expansion board 7 can be used to play the entire multi-step case cycle or the matters that need special attention are located in the middle expansion board 7 for display, and the display board 3 can be erected to facilitate the leader to explain to the small group, and the middle expansion board 7 can also be watched by people by themselves, and the display board 3 plays the safety accident cases that are prone to occur separately at each position, so as to display them separately and facilitate explanations, and the display effects are diverse. Secondly, each motor and switch can be controlled by one key through the console 11, and the motor three 36 can be controlled to reset by the console 11.

A switch 40 for controlling the cylinder 2 38 to be turned on separately is provided on the control console 11, and a switch 5 41 for controlling the cylinder 2 38 to be started synchronously with the motor 2 30 is provided on the control console 11. When in normal use, the display board 3 and the expansion board 7 are parallel to the ground, which is convenient for the leader to directly operate or point to the display screen for explanation to visitors or inspectors. If there are too many visitors, such as induction training and other concentrated introductions or training, the switch 5 41 on the control console for controlling the cylinder 2 38 and the motor 2 30 can be turned on, and at the same time, the expansion board 7 is driven to move and connect with the exhibition The display board 3 is flush, and then the cylinder 2 38 is driven to push the closing piece 5, and the slider 39 is pushed along the slide groove of the closing piece 5 by the piston of the cylinder 2 38 to push the closing piece 5 from the horizontal to the vertical setting, and when the piston of the cylinder 2 38 moves, it will rotate along the slider 39, and the closing piece 5 will also rotate simultaneously with the support frame 2, and the slider 39 moves up synchronously, ensuring that the closing piece 5 and the cylinder will not restrict each other. At the same time, after the cylinder 2 38 is pushed, the motor 2 30 will also push the expansion board 7 to the same height as the display board 3 through the rotation of the connecting rod 33, so that the entire expansion board 7 and the display board 3 can achieve the effect of large-screen display and introduction. This setting ensures that when there are many people explaining and training at the same time, too many people and people at a long distance can watch clearly. Secondly, the effect of synchronously adjusting the closing piece 5 and the expansion board 7 can be achieved through a switch.

[0020] After the above settings, when it is necessary to lead the inspection or the customer to visit, the display board 3 can be directly pushed to rotate and watch, and each display board 3 can play accident cases that are prone to occur at different positions during the processing, and explain and remind. Secondly, the leader can control the switch drive of the cylinder 1 23 by the console 11, so that the kit moves down and the driving wheel 17 is misaligned with the rack 18, the driving wheel 20 is engaged with the rack 2 19, and then the switch 1 21 is turned on, the motor 16 rotates to drive the plug-in 13 to move and embed into the card slot 12, and the rotating rod 14 is connected to the connecting rod 14. The rotating connection of the parts 6 enables the display board 3 to be rotated and erected, and each display board 3 can be individually played a problem that is easily encountered at a single position in the production process. Secondly, after the display board 3 is erected, the leader can give an explanation. Secondly, under normal use, the switch 5 41 can be turned on the console 11, and the driving motor 2 30 and the cylinder 2 38 are turned on synchronously. The motor 2 30 rotates to drive the clamped roller 32 to rotate, and moves along the slide rail 31 to the end of the slide rail 31, and drives the transmission wheel 1 34 and the connecting rod 33 to move at the same time during the movement, and drives the expansion board 7 to move through the connecting rod 33. The roller 32 moves to the bottom of the slide rail 31, and the transmission wheel 1 34 meshes with the rotating wheel 35. After the sensor senses the position of the transmission wheel 1 34, it outputs a signal to the controller on the motor 36 to drive the motor 36 to drive the rotating wheel 35 to rotate, and the transmission wheel 1 34 is pushed to rotate once to drive the connected connecting rod 33 to rotate, and at the same time, the expansion board 7 is pushed upward to be flush with the display board 3, forming an overall large-screen playback effect. Secondly, the cylinder 2 38 is also driven to push the slider 39 to move along the slide groove, so that the closing member 5 moves along the support frame 2, and at the same time, the piston of the cylinder 2 38 also rotates with the slider 39, so as to push the display board 3 and the expansion board 7 to switch from the horizontal state to the vertical state, and then move the entire display platform to the only way to enter the factory, play some accident cases in the food processing process to remind the employees and personnel entering the factory at all times. Under normal use, the display board 3 and the expansion board 7 are arranged horizontally, and some accident cases of entry are continuously played on the display board 3 in a loop to remind the staff entering, and the entire display platform is moved to a conspicuous or must-go position through the bottom wheels.
