[0024] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0025] Reference Figure 1 - Figure 7 As shown, the utility model provides a technical solution: a central control system for an exhibition hall, comprising a wall 1, a fixing block 2 is fixed on the top of the wall 1, L-shaped plates 3 are installed on both sides of the fixing block 2, a central control device body 4 is fixed on the side of the L-shaped plate 3 away from the fixing block 2, a connecting rod 5 is slidably connected inside the fixing block 2, a shell 6 is fixed on one side of the L-shaped plate 3, a fixing ring 7 is fixed inside the shell 6, a rotating shaft 8 is rotatably connected to the inside of the shell 6, an elliptical plate 9 is fixed at one end of the rotating shaft 8, a fixing mechanism for fixing the L-shaped plate 3 is installed inside the shell 6, and the central control device body 4 can be quickly installed by installing the fixing mechanism, which solves the problem of complicated installation process of the current central control device body 4, greatly reduces installation time and labor cost, and makes the central control device body 4 more convenient in later maintenance, reducing maintenance cost and time.

[0026] Reference Figure 1 - Figure 6As shown, in this embodiment: the fixing mechanism includes a transmission plate 10 slidably connected to both sides of the interior of the shell 6, a card block 11 is fixed at one end of the transmission plate 10, and both sides of the connecting rod 5 are provided with card slots 12. The card block 11 penetrates the fixing ring 7 and is slidably connected to the inside of the card slot 12. Both sides of the interior of the shell 6 are fixed with a first spring 15, and the other end of the first spring 15 is fixed to the transmission plate 10. The interior of the rotating shaft 8 is slidably connected with a sliding rod 16, and a knob 17 is fixed at one end of the sliding rod 16 away from the rotating shaft 8. A plug rod 18 is fixed to the side of the knob 17 close to the shell 6. A slot 19 is provided on one side of the shell 6, and the inside of the slot 19 is sleeved with the plug rod 18. The plug rod 18 is driven out of the inside of the slot 19 by pulling the knob 17. , and then turn the knob 17 to drive the shaft 8 to rotate, and at the same time rotate the elliptical plate 9 ninety degrees and place it vertically, so that the elliptical plate 9 pushes the transmission plate 10, and then drives the block 11 to disengage from the inside of the slot 12. At this time, the L-shaped plate 3 can be detached from the surface of the connecting rod 5, so that the user can quickly disassemble and maintain the central control device body 4. When the central control device body 4 needs to be installed, first put the L-shaped plate 3 and the shell 6 on the surface of the connecting rod 5 through their own notches, and rotate the elliptical plate 9 ninety degrees and place it horizontally. Then use the resilience of the first spring 15 to drive the transmission plate 10 to pull the block 11 into the slot 12, so that the central control device body 4 can be quickly installed and fixed.

[0027] Reference Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment: fixing rods 13 are fixed on both sides of the shell 6, and a through groove 14 is opened on the surface of the transmission plate 10. The inside of the through groove 14 is slidably connected with the surface of the fixing rod 13. By setting the structure of the fixing rod 13 and the through groove 14, the moving trajectory of the transmission plate 10 can be restricted to avoid tilting.

[0028] Reference Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment: both ends of the interior of the rotating shaft 8 are provided with a slide groove 20, and a slider 21 is slidably connected to the interior of the slide groove 20, and the other end of the slider 21 is fixed to the slide rod 16. By setting the structure of the slide groove 20 and the slider 21, the moving trajectory of the slide rod 16 can be restricted to prevent the user from using too much force when pulling the knob 17, causing the slide rod 16 to detach from the interior of the rotating shaft 8.

[0029] Reference Figure 1 , Figure 5 and Figure 6As shown, in the present embodiment: a second spring 22 is fixed inside the rotating shaft 8, and the other end of the second spring 22 is fixed to the sliding rod 16. By providing the second spring 22, when the user pulls the knob 17 to drive the sliding rod 16 to move outward, the second spring 22 begins to stretch, and then when the insertion rod 18 needs to be reset, the action force of the second spring 22 is utilized to drive the knob 17 to push the insertion rod 18 into the interior of the slot 19, thereby greatly saving manpower.

[0030] Working principle: the user pulls the knob 17 to drive the insertion rod 18 out of the slot 19, and then turns the knob 17 to drive the shaft 8 to rotate, and at the same time rotates the elliptical plate 9 ninety degrees to be placed vertically, so that the elliptical plate 9 pushes the transmission plate 10, and then drives the card block 11 to be out of the card slot 12. At this time, the L-shaped plate 3 can be detached from the surface of the connecting rod 5, so that the user can quickly disassemble and maintain the central control device body 4. When the central control device body 4 needs to be installed, first put the L-shaped plate 3 and the shell 6 on the surface of the connecting rod 5 through their own notches, and rotate the elliptical plate 9 ninety degrees to be placed horizontally, and then use the resilience of the first spring 15 to drive the transmission plate 10 to pull the card block 11 into The interior of the card slot 12 can realize the rapid installation and fixation of the central control device body 4. By setting the structure of the fixing rod 13 and the through slot 14, the movement trajectory of the transmission plate 10 can be restricted to avoid tilting. By setting the structure of the slide groove 20 and the slider 21, the movement trajectory of the slide bar 16 can be restricted to avoid the user from using too much force when pulling the knob 17, causing the slide bar 16 to disengage from the inside of the rotating shaft 8. By setting the second spring 22, when the user pulls the knob 17 to drive the slide bar 16 to move outward, the second spring 22 begins to stretch. Then, when the insertion rod 18 needs to be reset, the force of the second spring 22 is used to drive the knob 17 to push the insertion rod 18 into the inside of the slot 19, which greatly saves manpower.
