[0047] Example 1: In this example, the billboard is quickly stored and unfolded through the folding hinge structure, elastic telescopic positioning and locking snap-fit, which greatly saves carrying space and is suitable for outdoor mobile display scenarios.

[0048] Specifically, during storage, the operator holds the U-shaped handle 4 and pulls it upward along the storage groove 6 of the guide frame 3. The U-shaped handle 4 drives the two side support rods 7 to move synchronously. The slider 22 at the outer end of the support rod 7 slides smoothly along the slide groove 21 of the guide frame 3 to avoid deviation. The adjusting spring telescopic rod 8 is compressed, and the insertion end of the U-shaped handle 4 gradually retracts into the guide hole 2 until it is fully stored. Then, the lower frame plate 9 is folded upward around the hinge with the upper frame plate 1. The locking blocks 16 on both sides of the lower frame plate 9 gradually approach the snap-fit ​​groove 13 of the upper frame plate 1. The pressing surface 18 of the locking block 16 slides and fits against the inclined surface 17 of the guide block 15, squeezing the guide block 15 to retract inward along the snap-fit ​​groove 13, and the locking spring telescopic rod 14 is compressed.

At this time, the U-shaped handle 4 is reset under the action of the adjusting spring telescopic rod 8, and the locking block 5 is locked on the limiting plate 10, further fixing the structure. The overall size is compact and easy to carry.

[0049] During unfolding, the operator uses wrench 20 to pull guide block 15, releasing it from the locking groove 19, causing the locking spring telescopic rod 14 to retract. The lower shelf 9 naturally flips under gravity. When guide hole 2 aligns with insertion hole 12 of lower shelf 9, the U-shaped handle 4 is released, and spring telescopic rod 8 is adjusted to push U-shaped handle 4 back to its original position. Its insertion end passes through guide hole 2 and inserts into insertion hole 12. Locking block 5 engages with storage groove 6 to lock the unfolding angle of upper shelf 1 and lower shelf 9. Finally, the support frame 25 in the rear wall groove 23 of lower shelf 9 is flipped around the transition shaft 24 until it forms a 30-degree angle with lower shelf 9, providing stable support and completing the display frame construction.

[0050] Example 2: In this example, the advertisement is stored in a storage bucket, and the limiting nails are used for precise fixation and weight-added to assist in stability, so as to realize the rapid replacement of advertisements and stable display in multiple scenarios, which is suitable for the needs of outdoor mobile advertising.

[0051] Specifically, before displaying, unscrew the locking cap 28 of the advertising storage bucket 26, take out the rolled-up advertising body 27 from the bucket, unfold it, align the limiting holes 30 at its four corners with the limiting nails 29 on the outer walls of the upper shelf 1 and lower shelf 9, and insert them one by one to fix it, preventing the advertising body 27 from shifting or wrinkling, and ensuring a flat display effect. If used in a windy or uneven environment, unscrew the locking cap 28 and put a water bottle filled with water or other heavy objects into the advertising storage bucket 26 to increase the weight of the bottom of the billboard and improve its anti-tipping ability.

[0052] The display frame is then constructed following the unfolding steps of Example 1. The support frame 25 forms a triangular support structure in contact with the ground, further enhancing stability. The advertising storage bin 26 is fixed to the limiting plate 10, serving both to store spare advertisements and to assist in balance through internal weights, preventing the billboard from swaying during display. When replacing an advertisement, simply remove the old advertisement body 27, take the new advertisement out of the storage bin, and repeat the fixing steps. No complicated tools are required throughout the process, making the operation efficient and convenient.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
