[0007] The front end of the support leg is equipped with a fixing mechanism for fixing the mounting plate.

[0008] Preferably, the fixing mechanism includes four limiting holes on both sides of the first hollow block. The limiting holes are distributed on both sides of the first hollow block. A limiting rod is slidably connected inside the limiting hole. A connecting plate is fixed to one end of the limiting rod. A through hole is opened at the rear end of the support leg. A rotating rod is rotatably connected inside the through hole. An elliptical block is fixed to the front end of the rotating rod. A knob is installed at the rear end of the rotating rod.

[0009] Preferably, a tension rod is slidably connected inside the rotating rod, the rear end of the tension rod is fixed to one end of the knob, a limit groove is formed at the rear end of the support leg, and a limit block is fixed to one end of the knob.

[0010] Preferably, one end of the tension rod is fixed with a tension spring, and the other end of the tension spring is fixed to one end inside the rotating rod.

[0011] Preferably, the top and bottom of the rotating rod are provided with limiting grooves, and the top and bottom of the tension rod are fixed with limiting sliders.

[0012] Preferably, a thrust spring is fixed to one side of the connecting plate, and the other end of the thrust spring is fixed to the inner wall of the second hollow block.

[0013] Preferably, the top and bottom of the second hollow block are provided with first sliding grooves, and the top and bottom of the connecting plate are fixed with first sliders.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] In this invention, the user inserts the connecting rod into the groove on the support leg, so that the support leg is located at both ends of the connecting rod.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0024] Reference Figure 1 - Figure 3 As shown, this utility model provides a technical solution: an easy-to-install advertising board, including a support leg 1, an installation plate 2 installed at the front end of the support leg 1, a transparent protective plate 3 fixed at the front end of the installation plate 2, a groove 4 opened on one side of the support leg 1, a connecting rod 5 slidably connected inside the groove 4, two first hollow blocks 6 fixed at the rear end of the installation plate 2, and a second hollow block 7 fixed at the front end of the support leg 1. A fixing mechanism for fixing the installation plate 2 is installed at the front end of the support leg 1. The user inserts the connecting rod 5 into the groove 4 opened on the support leg 1, so that the support leg 1 is located at both ends of the connecting rod 5, which makes it easy to align the first hollow block 6 at the rear end of the installation plate 2 with the second hollow block 7 at the front end of the support leg 1, preventing misalignment when installing the support leg 1 and the installation plate 2. After the support leg 1 and the installation plate 2 are spliced ​​together, the advertising brochure is placed between the installation plate 2 and the transparent protective plate 3 for display.

[0025] Reference Figure 3 , Figure 4 and Figure 5As shown in this embodiment: the fixing mechanism includes four limiting holes 8 on both sides of the first hollow block 6. The limiting holes 8 are distributed on both sides of the first hollow block 6. A limiting rod 9 is slidably connected inside the limiting hole 8. A connecting plate 10 is fixed to one end of the limiting rod 9. A through hole 11 is opened at the rear end of the support leg 1. A rotating rod 12 is rotatably connected inside the through hole 11. An elliptical block 13 is fixed to the front end of the rotating rod 12. A knob 14 is installed at the rear end of the rotating rod 12. The user inserts the connecting rod 5 into the groove 4 opened on the support leg 1, so that the support leg 1 is located at both ends of the connecting rod 5. The user inserts the first hollow block 6 at the rear end of the mounting plate 2 into the second hollow block 7 at the front end of the support leg 1. The user rotates the knob 14, which drives the elliptical block 13 at the front end of the rotating rod 12 to rotate. Since the diameter of the elliptical block 13 is different at each position, the elliptical block 13 will push the connecting plate 10 to both sides during the rotation of the elliptical block 13, so that the limiting rod 9 on the outside of the connecting plate 10 enters the interior of the limiting hole 8, thereby fixing the mounting plate 2.

[0026] Reference Figure 5 As shown in this embodiment: a tension rod 18 is slidably connected inside the rotating rod 12. The rear end of the tension rod 18 is fixed to one end of the knob 14. A limit groove 19 is opened at the rear end of the support leg 1. A limit block 20 is fixed at one end of the knob 14. The user inserts the first hollow block 6 at the rear end of the mounting plate 2 into the second hollow block 7 at the front end of the support leg 1. Rotating the knob 14 causes the elliptical block 13 at the front end of the rotating rod 12 to rotate, so that the limit rod 9 on the outside of the connecting plate 10 enters the interior of the limit hole 8 to fix the mounting plate 2. After the mounting plate 2 is installed, the knob 14 is pushed to drive the limit block 20 into the interior of the limit groove 19 to limit the elliptical block 13, preventing the elliptical block 13 from rotating and failing to limit the connecting plate 10, causing the limit rod 9 to be vibrated and dislodged from the interior of the limit hole 8.

[0027] Reference Figure 5 As shown in this embodiment: one end of the tension rod 18 is fixed with a tension spring 21, and the other end of the tension spring 21 is fixed to one end of the rotating rod 12. When the user rotates the knob 14, the elliptical block 13 at the front end of the rotating rod 12 rotates, so that the limiting rod 9 on the outside of the connecting plate 10 enters the interior of the limiting hole 8 to fix the mounting plate 2. At the same time, the limiting block 20 is aligned with the position of the limiting groove 19. When the knob 14 is released, under the tension of the tension spring 21, the knob 14 is pulled to move into the rotating rod 12, so that the limiting block 20 enters the interior of the limiting groove 19 to limit the elliptical block 13.

[0028] Reference Figure 5As shown in this embodiment: the top and bottom of the rotating rod 12 are provided with limiting grooves 22, and the top and bottom of the tension rod 18 are fixed with limiting sliders 23. When the user needs to remove the mounting plate 2, he pulls the knob 14 to make the limiting block 20 disengage from the inside of the limiting groove 19, rotates the knob 14 to drive the elliptical block 13 to rotate, release the limitation on the limiting rod 9, push the limiting rod 9 from the inside of the limiting hole 8 to move into the inside of the second hollow block 7, so that the limiting rod 9 disengages from the inside of the limiting hole 8, and releases the limitation on the mounting plate 2. During the process of pulling the knob 14, the limiting sliders 23 at the top and bottom of the tension rod 18 move inside the limiting grooves 22 to limit the movement of the tension rod 18 and prevent the tension rod 18 from disengaging from the inside of the rotating rod 12.

[0029] Reference Figure 3 As shown in this embodiment: a thrust spring 15 is fixed on one side of the connecting plate 10, and the other end of the thrust spring 15 is fixed to the inner wall of the second hollow block 7. When the user needs to remove the mounting plate 2, he pulls the knob 14 to make the limiting block 20 disengage from the inside of the limiting groove 19, rotates the knob 14 to drive the elliptical block 13 to rotate, and releases the limitation on the limiting rod 9. Under the thrust of the thrust spring 15, the connecting plate 10 is pushed to move towards the middle of the second hollow block 7, and the limiting rod 9 is disengaged from the inside of the limiting hole 8, thus releasing the limitation on the mounting plate 2.

[0030] Reference Figure 6 As shown in this embodiment: the top and bottom of the second hollow block 7 are provided with first sliding grooves 16, and the top and bottom of the connecting plate 10 are fixed with first sliders 17. When the user rotates the knob 14, the elliptical block 13 rotates, releasing the limit rod 9. Under the push of the push spring 15, the connecting plate 10 is pushed to move towards the middle of the second hollow block 7. During the movement of the connecting plate 10, the first sliders 17 at the top and bottom of the connecting plate 10 move inside the first sliding grooves 16 to assist the movement of the connecting plate 10 and prevent the connecting plate 10 from tilting after the limit rod 9 leaves the inside of the limit hole 8.

[0031] Working principle: The user inserts the connecting rod 5 into the groove 4 on the support leg 1, positioning the support leg 1 at both ends of the connecting rod 5. This facilitates aligning the first hollow block 6 at the rear end of the mounting plate 2 with the second hollow block 7 at the front end of the support leg 1, preventing misalignment during installation. After assembling the support leg 1 and mounting plate 2, the brochure is placed between the mounting plate 2 and the transparent protective plate 3 for display. The user then inserts the connecting rod 5 into the groove 4 on the support leg 1, positioning the support leg 1 at both ends of the connecting rod 5. The user then aligns the first hollow block 6 at the rear end of the mounting plate 2 with the second hollow block 7 at the front end of the support leg 1. Rotating the knob 14 causes the elliptical block 13 at the front end of the rotating rod 12 to rotate. Due to the different positions of the elliptical block 13... Due to their different diameters, the elliptical block 13 pushes the connecting plate 10 to both sides during rotation, causing the limiting rod 9 on the outer side of the connecting plate 10 to enter the limiting hole 8 and fix the mounting plate 2. The first hollow block 6 at the rear end of the mounting plate 2 is then aligned with the second hollow block 7 at the front end of the support leg 1 and inserted. Rotating the knob 14 causes the elliptical block 13 at the front end of the rotating rod 12 to rotate, causing the limiting rod 9 on the outer side of the connecting plate 10 to enter the limiting hole 8 and fix the mounting plate 2. After the mounting plate 2 is installed, pushing the knob 14 causes the limiting block 20 to enter the limiting groove 19 and limit the elliptical block 13, preventing it from rotating and thus preventing the connecting plate 10 from being limited. Rotating the knob 14 causes the elliptical block 13 at the front end of the rotating rod 12 to rotate. The limiting rod 9 on the outside of the connecting plate 10 is inserted into the limiting hole 8 to fix the mounting plate 2. At the same time, the limiting block 20 is aligned with the limiting groove 19. The knob 14 is released, and under the tension of the tension spring 21, the knob 14 is pulled to move into the rotating rod 12, so that the limiting block 20 enters the limiting groove 19 and limits the elliptical block 13. When the mounting plate 2 is removed, the knob 14 is pulled to disengage the limiting block 20 from the limiting groove 19. The knob 14 is rotated to rotate the elliptical block 13, releasing the limitation on the limiting rod 9. The limiting rod 9 is pushed from the inside of the limiting hole 8 into the inside of the second hollow block 7, so that the limiting rod 9 disengages from the inside of the limiting hole 8 and releases the limitation on the mounting plate 2. During the pulling of the knob 14, the tension rod 18 pushes the rod 18 to move into the second hollow block 7. The limiting sliders 23 at the top and bottom move inside the limiting groove 22, limiting the movement of the tension rod 18 and preventing it from disengaging from the rotating rod 12. When the mounting plate 2 needs to be removed, pull the knob 14 to disengage the limiting block 20 from the limiting groove 19. Rotate the knob 14 to rotate the elliptical block 13, releasing the limiting rod 9. Under the thrust of the thrust spring 15, push the connecting plate 10 towards the center of the second hollow block 7, causing the limiting rod 9 to disengage from the limiting hole 8, releasing the limiting of the mounting plate 2. Rotate the knob 14 to rotate the elliptical block 13, releasing the limiting rod 9. Under the thrust of the thrust spring 15, push the connecting plate 10 towards the center of the second hollow block 7. During the movement of the connecting plate 10...The first sliders 17 at the top and bottom of the connecting plate 10 move inside the first groove 16, assisting the movement of the connecting plate 10 and preventing the connecting plate 10 from tilting after the limiting rod 9 disengages from the limiting hole 8.
