Posting slots are opened on the front sides of both the first bulletin board 1 and the second bulletin board 2.

[0029] The rotating rod 7 facilitates the rotation of the gear 8. The meshing of the gear 8 and rack 6, combined with the movement of the second advertising board 2 and the movable groove 3, allows the second advertising board 2 to be moved outwards from the movable groove 3, expanding the display area of ​​the advertising display. The limiting groove 15, guide rod 16, and guide block 17 effectively limit and guide the second advertising board 2, preventing it from falling out of the movable groove 3 during outward movement. Simultaneously, the grip rod 9, slot 10, locking block 11, spring 12, positioning hole 13, and positioning block 14 lock and limit the rotating rod 7, preventing free rotation and ensuring the stability of the gear 8. This prevents the second advertising board 2 from sliding freely, thus ensuring its stability during use and storage.

[0030] The grip 9 has a hollow structure and is movably sleeved on the outside of the rotating rod 7. Several slots 10 are opened opposite each other on the outer wall of the rotating rod 7, and several blocks 11 are fixed opposite each other on the inner wall of the grip 9. The blocks 11 and the slots 10 correspond one-to-one and cooperate with each other. The spring 12 is fixed between the rear end of the rotating rod 7 and the inner wall of the grip 9. Several positioning holes 13 are opened on the rear surface of the first advertising board 1, and the positioning holes 13 are arranged in a circular shape on the periphery of the rotating rod 7. The positioning block 14 is fixed on the outer wall of the grip 9, and the positioning block 14 cooperates with the positioning hole 13.

[0031] The limiting groove 15 is opened at the bottom of the inner wall of the movable groove 3. Several guide rods 16 are fixed inside the limiting groove 15. The guide block 17 is slidably sleeved between the several guide rods 16, and the top of the guide block 17 is fixedly connected to one side of the bottom of the second advertising board 2. Through the sliding cooperation between the guide block 17 and the guide rods 16, the second advertising board 2 is effectively limited and guided, ensuring the stability of the second advertising board 2 during the process of pulling outward and retracting inward, while preventing the second advertising board 2 from falling out of the movable groove 3.

[0032] The height adjustment mechanism includes a base 18, sleeves 19, piston rod 20, lead screw 21, threaded sleeve 22, tubing 23, and self-locking casters 24. The base 18 is located below the first advertising board 1. Two sleeves 19 are fixedly fixed to the top of the base 18. The piston rod 20 has a T-shaped cross-section and is movable within the inner cavity of the sleeves 19. The upper end of the piston rod 20 is fixedly connected to the bottom of the first advertising board 1. The lead screw 21 is fixed at the center of the top of the base 18. The threaded sleeve 22 is threaded onto the lead screw 21. The tube 23 is fixed to the bottom of the first advertising board 1. The top of the threaded sleeve 22 is rotatably connected to the bottom of the sleeve 23. The screw 21 is movablely engaged with the inner cavity of the sleeve 23. Several self-locking casters 24 are installed opposite each other at the bottom of the base 18. A pull rod 25 is fixed on the side of the fixing plate 4 away from the second advertising board 2. The pull rod 25 and the self-locking casters 24 facilitate the overall movement of the advertising board. Several reinforcing rods 26 are inclinedly fixed between the lower side of the outer wall of the sleeve 19 and the base 18 to ensure the stability between the sleeve 19 and the base 18. Example

[0033] In use, first pull the lever 25 and use the self-locking caster 24 to adjust the bulletin board to move. After the bulletin board is moved to the appropriate position, use the self-locking function of the caster 24 to fix the bottom of the bulletin board.

[0034] Staff members affixed promotional leaflets printed with employment guidance information to the posting slots on the first promotional board 1 for people to view, thus achieving the desired promotional effect.

[0035] When it is necessary to expand the display area of ​​the bulletin board, with the cooperation of the handle 9 and the rotating rod 7, and in conjunction with the cooperation of the locking block 11 and the locking slot 10, the handle 9 is adjusted to move away from the first bulletin board 1 and the spring 12 is stretched until the positioning block 14 is disengaged from the corresponding positioning hole 13. Then the handle 9 is rotated, and under the joint action of the locking block 11 and the locking slot 10, the rotating rod 7 is moved to rotate synchronously.

[0036] The rotation of the rotating rod 7 drives the gear 8 to rotate. Combined with the meshing of the gear 8 and the rack 6, and the sliding engagement of the guide block 17 and the guide rod 16, the second advertising board 2 is moved to the outside of the movable groove 3. After the second advertising board 2 moves to the appropriate position outside the movable groove 3, the grip rod 9 is released. Under the elastic action of the spring 12, the grip rod 9 is pulled to move closer to the first advertising board 1. During this process, the grip rod 9 is finely adjusted until the positioning block 14 is inserted into the positioning hole 13 at the corresponding position.

[0037] The positioning block 14 is inserted into the positioning hole 13 to limit and fix the gripping rod 9. With the cooperation of the locking block 11 and the locking groove 10, the rotating rod 7 is limited and fixed to prevent it from rotating freely. This also limits and fixes the gear 8. The meshing action of the gear 8 and the rack 6 limits the rack 6 to ensure its stability. By fixing the rack 6, the second advertising board 2 is limited and fixed, ensuring its stability in use. This solves the problem in the prior art where the spare advertising board is easily pulled out of the groove, affecting its adjustment and use. It also solves the problem in the prior art where after the spare advertising board is extended to a suitable distance, the staff needs to manually adjust the second screw to fix it. Furthermore, because the advertising board has a certain height, it is inconvenient for the staff to adjust the second screw at the top of the advertising board, which affects the use of the advertising board.

[0038] Finally, the staff will paste the promotional paper into the posting slot on the second promotional board 2.

[0039] When the height of the bulletin board needs to be adjusted, the threaded sleeve 22 rotates under the rotational connection between the threaded sleeve 22 and the sleeve 23. Combined with the threaded engagement between the threaded sleeve 22 and the lead screw 21, and the movable engagement between the lead screw 21 and the inner cavity of the sleeve 23, the threaded sleeve 22 rotates upward along the direction of the lead screw 21. Combined with the movable engagement between the piston rod 20 and the sleeve 19, the first bulletin board 1 is lifted upward, thereby achieving the purpose of adjusting the height of the bulletin board.

[0040] It should be further noted that the installation structure, connection method or setting method of each component in this utility model are all common mechanical methods, and any method that can achieve its beneficial effect can be implemented.

[0041] All technical features in this embodiment can be freely combined according to actual needs.
