[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1) When the posters inside the land use protection publicity device need to be replaced, first, grip the handle tightly and pull it outward to move the slider outward. At the same time, press the pressing block and push down the top rod to push the locking block to slide on the inner wall of the sliding sleeve. At this time, the horizontal plate pulls the first return spring to stretch and the second return spring to compress, thereby accumulating potential energy. When the locking block disengages from the locking slot, pull the handle and slider to disengage from the mounting base. Then, the posters can be replaced by the cooperation of the magnetic block and the iron plate. This can speed up the replacement of posters and further improve the replacement efficiency of the device.

[0016] 2) This land use protection publicity device absorbs sunlight through solar panels and transmits electricity to the lighting fixtures via transmission lines, providing illumination inside the mounting frame. The mounting plate also isolates the device from rainwater, providing a safe observation environment. Before replacing the posters, the locking mechanism is opened, the handle is gripped, and pulled outwards. This causes the cover plate to rotate around the hinge, opening the cover. The posters can then be replaced using the replacement mechanism. This device provides lighting and energy, and its position can be adjusted via casters, enhancing its applicability and practicality.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0025] Combination Figures 1-6A land use protection publicity device includes a mounting frame 4, a back plate 5 fixedly mounted on the side of the mounting frame 4, a lighting and opening / closing mechanism 6 fixedly mounted on the side of the mounting frame 4, and a replacement mechanism 7 fixedly mounted on the side of the back plate 5. The replacement mechanism 7 includes a mounting base 701, a mounting groove fixedly opened on the side of the mounting base 701, a side plate 702 fixedly mounted on the inner wall of the mounting groove, a through hole extending vertically through the side plate 702, a pressing block 703 slidably mounted on the inner wall of the through hole, a top rod 704 fixedly mounted on the bottom end face of the pressing block 703, a horizontal plate 705 fixedly mounted on the side of the top rod 704, a first return spring 706 fixedly mounted on the top end face of the horizontal plate 705, the top end face of the first return spring 706 fixedly connected to the bottom end face of the side plate 702, a sliding sleeve 707 slidably mounted on the side of the top rod 704, and a fixing block 707 fixedly mounted on the side of the sliding sleeve 707. 8. The side of the fixing block 708 is fixedly connected to the inner wall of the mounting groove. The side of the sliding sleeve 707 is fixedly installed with the connecting block 709. The side of the connecting block 709 is fixedly installed with the sliding sleeve 710. The bottom end face of the sliding sleeve 710 is fixedly connected to the inner wall of the mounting groove. The inner wall of the sliding sleeve 710 is slidably installed with the slider 713. The end face of the slider 713 is fixedly installed with the second return spring 712. The end face of the second return spring 712 is fixedly connected to the inner wall of the mounting groove. The inner wall of the mounting base 701 is slidably installed with the slider 713. The side of the slider 713 is fixedly installed with the bayonet 714. The inner wall of the bayonet 714 is engaged with the side of the bayonet block 711. The side of the slider 713 is fixedly installed with the handle 715. The side of the slider 713 is fixedly installed with the iron plate 8. The side of the iron plate 8 is fixedly installed with the rubber plate 9. The side of the rubber plate 9 is pressed and contacted by the magnetic block to install the promotional poster.

[0026] Specifically, in use, the device is moved to the designated advertising location using the casters 2, and then the casters 2 are locked for advertising operations. When it is necessary to replace the advertising posters inside the device, first, the mounting frame 4 is opened using the lighting and opening / closing mechanism 6, then the handle 715 is gripped and pulled outwards. The handle 715 drives the slider 713 to move outwards. At the same time, the pressing block 703 is pressed down, and the pressing block 703 presses down the top rod 704. The inclined surface of the top rod 704 pushes the locking block 711 to slide on the inner wall of the sliding sleeve 710, compressing the second return spring 712 to contract and accumulate elastic potential energy. At this time, the horizontal plate 705 follows the downward movement of the top rod 704 to pull the first When the return spring 706 is stretched, and the locking block 711 retracts to disengage from the locking slot 714, the handle 715 and the slider 713 are pulled away from the mounting base 701. Then, the poster is replaced by the cooperation of the magnet block and the iron plate 8. After the replacement is completed, the side of the slider 713 is aligned with the slide rail opened inside the mounting base 701 and pushed inward. At this time, the end face of the slider 713 presses against the locking block 711 and compresses the second return spring 712. When the slider 713 moves inward to the locking slot 714 and matches the locking block 711, the second return spring 712 pushes the locking block 711 into the locking slot 714 to engage, thus completing the installation of the poster.

[0027] In this embodiment, the side plate 702 restricts the horizontal movement of the pressing block 703. The sliding sleeve 707, the fixing block 708, and the connecting block 709 respectively limit the movement of the top rod 704; fix the component to the inner wall of the mounting groove; the connecting block 709 connects the sliding sleeve 707 and the sliding sleeve 710; and the rubber plate 9 acts as a buffer to make the display of the promotional poster softer. Example 2

[0028] See Figures 1-6 Furthermore, the lighting and opening / closing mechanism 6 includes a lighting lamp 601, the top surface of which is fixedly connected to the inner wall of the mounting frame 4. A back plate 5 is fixedly installed on the side of the mounting frame 4, the side of which is fixedly connected to the side of the mounting base 701. A hinge 605 is fixedly installed on the side of the back plate 5, a cover plate 606 is fixedly installed on the side of the hinge 605, a handle 608 is fixedly installed on the side of the cover plate 606, a locking component 607 is fixedly installed on the side of the cover plate 606, the side of the locking component 607 is lockedly connected to the side of the mounting frame 4, a mounting plate 602 is fixedly installed on the top surface of the mounting frame 4, a support block 603 is fixedly installed on the top surface of the mounting plate 602, a solar panel 604 is fixedly installed on the top surface of the support block 603, a support leg 3 is fixedly installed on the bottom surface of the mounting frame 4, the bottom surface of the support leg 3 is fixedly connected to the top surface of the base plate 1, and a caster wheel 2 is fixedly installed on the bottom surface of the base plate 1.

[0029] Specifically, in use, the solar panel 604 absorbs sunlight and transmits electricity to the lighting lamp 601 via a transmission line, providing illumination to the interior of the mounting frame 4. This ensures that the device can still play a good advertising role even in low light conditions, and the mounting plate 602 can isolate rainwater, providing a safer and more comfortable observation environment for observers on rainy days. Before replacing the advertising poster, first, grip the locking component 607 and open it with the key. Then, grip the handle 608 and deflect the cover plate 606 outward with the hinge 605 as the center to open the cover plate 606. At this point, the advertising poster can be replaced using the replacement mechanism 7. After replacement, close the cover plate 606 with the hinge 605 as the center and lock the locking component 607 to isolate rainwater and protect the device from damage.
