[0003] To address the shortcomings of existing technologies, this utility model provides a promotional display board, including a base plate. A fixing rod is fixedly connected to the upper end of the base plate, and a placement plate is provided at the upper end of the fixing rod. Two fixing grooves are formed at the front of the placement plate, and retaining rings are fixedly connected inside each of the two fixing grooves. A slot is formed at the front end of the placement plate, and a display board body is placed inside the slot. Connecting plates are fixedly connected to the left and right ends of the display board body, and retaining plates are fixedly connected to the rear ends of the two connecting plates. Two springs are fixedly connected inside each of the two retaining rings, and protrusions are connected between the adjacent ends of the four springs. Slots that match the protrusions are formed at the upper and lower ends of the two retaining plates.
[0004] Optionally, each of the two retaining rings has four movable slots inside, and each of the eight movable slots has a movable block slidably connected inside, with the eight movable blocks being fixedly connected to the four protrusions respectively.
[0005] Optionally, each of the eight movable blocks is fixedly connected to a fixed plate at its upper end, and two fixed plates located on the same horizontal line are fixedly connected to a push plate at their upper ends.
[0006] Optionally, the upper end of the base plate is provided with four ground nail grooves.
[0007] Optionally, a rotating block is slidably connected to the circumferential surface of the fixed rod, and a locking block is fixedly connected to the circumferential surface of the fixed rod.

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0018] like Figure 1-4 As shown, a promotional display board includes a base plate 1. A fixing rod 2 is fixedly connected to the upper end of the base plate 1. A placement plate 4 is provided at the upper end of the fixing rod 2. Two fixing grooves 21 are opened at the front end of the placement plate 4. A retaining ring 9 is fixedly connected inside the two fixing grooves 21. A slot 5 is opened at the front end of the placement plate 4. A display board body 6 is provided inside the slot 5. Connecting plates 7 are fixedly connected to both the left and right ends of the display board body 6. A retaining plate 8 is fixedly connected to the rear end of the two connecting plates 7. Two springs 10 are fixedly connected inside the two retaining rings 9. A protrusion 11 is connected between the close ends of the four springs 10. The upper and lower ends of the two retaining plates 8 are provided with slots that are adapted to the protrusions 11.
[0019] The aforementioned promotional display board features a fixing groove 21 inside the placement plate 4, with a retaining ring 9 fixedly connected inside the fixing groove 21. When the position of the display board body 6 needs to be fixed, the display board body 6 moves the connecting plate 7, causing the connecting plate 7 to move the retaining plate 8 into the retaining ring 9. When the retaining plate 8 contacts the protrusion 11, the protrusion 11 retracts inward. Since the retaining plate 8 has a slot that matches the protrusion 11, the reaction force of the spring 10 causes the protrusion 11 to enter the slot inside the retaining plate 8, thus easily stabilizing the position of the display board body 6. When the display board body 6 needs to be replaced, the protrusion 11 is moved, causing it to disengage from the slot. This makes it more convenient to change the display for different scenarios or different content.
[0020] In another embodiment, each of the two retaining rings 9 has four movable slots 12 inside, and each of the eight movable slots 12 has a movable block 13 slidably connected inside, and the eight movable blocks 13 are fixedly connected to the four protrusions 11 respectively. For example, when the protrusion 11 moves, the movement of the protrusion 11 can be limited by the fixed connection between the moving block 13 and the protrusion 11 and the moving block 13 sliding inside the moving groove 12.
[0021] In another embodiment, the upper ends of the eight movable blocks 13 are all fixedly connected to fixed plates 14, and the upper ends of the two fixed plates 14 located on the same horizontal line are fixedly connected to push plates 15. For example, when it is necessary to remove the protrusion 11 from the interior of the card plate 8, the moving plate 15 can be moved to move the moving block 13 at the same time. Since the moving block 13 is fixedly connected to the protrusion 11, the protrusion 11 can be removed from the interior of the card plate 8.
[0022] In another embodiment, four ground nail grooves 3 are provided at the upper end of the base plate 1; For example, when fixing the position of the base plate 1, the position of the base plate 1 can be fixed by cooperating with the ground nail and the ground nail groove 3.
[0023] In another embodiment, a rotating block 16 is slidably connected to the circumferential surface of the fixed rod 2, and a locking block 17 is fixedly connected to the circumferential surface of the fixed rod 2. The upper end of the locking block 17 is provided with multiple limiting grooves 18, and the lower end of the rotating block 16 is fixedly connected with multiple limiting rods 19. The multiple limiting rods 19 are all dimensionally adapted to the multiple limiting grooves 18. For example, when it is necessary to adjust the angle of the placement plate 4, the position of the locking block 17 is raised so that the limiting rod 19 is disengaged from the inside of the limiting groove 18. At this time, the rotating block 16 can be rotated. When it is rotated to the appropriate position, the rotating block 16 is lowered so that the limiting rod 19 enters the inside of the limiting groove 18, thereby fixing the position of the limiting rod 19 and adjusting the angle of the placement plate 4.
[0024] In another embodiment, a transparent protective plate 20 is fixedly installed at the front end of the placement plate 4 by a snap fastener, and the transparent protective plate 20 is positioned corresponding to the display plate body 6. For example, installing a transparent protective plate 20 on the placement plate 4 can protect the display plate body 6.
[0025] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
