[0012] 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.

[0013] Please see Figure 1-5 This utility model discloses a foldable screen-style movable advertising display board. Specifically, it is a movable advertising display board that achieves folding by rolling up the advertising cloth and closing the supports, balancing display and portability. It includes two supports 9, each with four existing rollers 10 with foot brakes installed at the bottom. A rotating rod 2 is rotatably mounted on the top of one support 9 via a bearing 15, and a fixing rod 7 is fixed on the top of the other support 9. The fixing rod 7 can detachably fix one end of the advertising cloth 5, and the rotating rod 2 can detachably fix the other end of the advertising cloth 5. With the above structure, when not in use, the advertising cloth 5 can be rolled up by rotating the rotating rod 2. After the advertising cloth 5 is rolled up, the two supports 9 are close to each other, which can greatly reduce the space occupied. When in use, the two supports 9 can be pulled apart. During the separation of the two supports 9, the rotating rod 2 unrolls the advertising cloth 5, so that the advertising cloth 5 can be fully displayed.

[0014] Furthermore, to facilitate the unwinding and rewinding of the advertising cloth 5, such as... Figure 2As shown, a first bevel gear 11 is fixed to the lower end of the rotating rod 2, and an L-shaped fixing frame is fixed to the upper end of the support 9 corresponding to the rotating rod 2. A second bevel gear 14 is rotatably mounted on the fixing frame via a rotating shaft. The second bevel gear 14 meshes with the first bevel gear 11. A locking bolt 12 is threaded to the upper end of the fixing frame. The locking bolt 12 passes through the side of the rotating shaft of the second bevel gear 14. In use, the rotation of the second bevel gear 14 can drive the first bevel gear 11 to rotate. When the first bevel gear 11 rotates, it drives the rotating rod 2 to rotate. When the rotating rod 2 rotates, it can roll up and unroll the advertising cloth 5. In addition, when it is necessary to fix the rotating rod 2, the locking bolt 12 can be rotated so that the lower end of the locking bolt 12 is inserted into the side of the rotating shaft of the second bevel gear 14 to restrict the rotation of the second bevel gear 14. Specifically, the side of the second bevel gear 14 has a through hole (not shown in the figure). The locking bolt 12 can be inserted into the through hole to limit the rotation.

[0015] like Figure 3 and Figure 4 As shown, the fixed rod 7 and the rotating rod 2 are embedded with a fixed groove 1 on their sides. The two ends of the advertising cloth 5 are detachably locked in the fixed groove 1. The fixed groove 1 is threaded with a fixed bolt 3. The advertising cloth 5 is provided with a fixed hole 19 corresponding to the fixed bolt 3. When installing the advertising cloth 5, first insert the two ends of the advertising cloth 5 into the fixed groove 1, then thread the fixed bolt 3 with the fixed rod 7 and the rotating rod 2, and insert the fixed bolt 3 into the fixed hole 19.

[0016] To facilitate the connection between the two supports 9 after the advertising cloth 5 is rolled up, a connecting mechanism is provided between the two supports 9.

[0017] In some embodiments, the connecting mechanism includes an insert plate 16 fixed to the right side of one of the supports 9 and a connecting block 17 with a slot fixed to the left side of the other support 9. The insert plate 16 is movably inserted into the slot, and a connecting bolt 18 is threaded onto the connecting block 17. The insert plate 16 has a connecting hole corresponding to the connecting bolt 18. When the advertising cloth 5 is rolled up, the two supports 9 are just abutting together, so that the insert plate 16 is inserted into the slot of the connecting block 17. By rotating the connecting bolt 18, the connecting bolt 18 is inserted into the connecting hole to fix the insert plate 16, thereby fixing the two supports 9.

[0018] Furthermore, to prevent the advertising cloth 5 from accumulating dust when not in use, such as... Figure 5 As shown, the upper ends of the two supports 9 are detachably covered with dust covers 20, which cover the fixing rod 7, the rotating rod 2, and the advertising cloth 5 inside.

[0019] This utility model aims to replace the traditional rigid display board with a flexible advertising cloth 5. By rotating the advertising cloth 5 and folding the double supports 9 together, the large-area display function of the screen is retained, while solving the problems of large storage space and inconvenient transportation of traditional display boards. It achieves the effect of both display stability and convenient storage and transportation, meeting the needs of flexible arrangement and rapid transfer in exhibition, promotion and other scenarios.

[0020] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment all adopt the prior art, and the conventional models will not be described in detail here.

[0021] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0022] 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.
