[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.

[0025] Please see Figures 1 to 5 A display rack for conferences and exhibitions includes a winding drum 1 and a backdrop 2 inside the winding drum 1. The bottom end of the backdrop 2 extends from the bottom of the winding drum 1 and is fixedly connected to a pull strip 3. By pulling the pull strip 3, the backdrop 2 can smoothly extend out of the interior of the winding drum 1.

[0026] The bottom of both ends of the take-up drum 1 is hinged with an upper bracket 4, which can rotate relative to the take-up drum 1. The bottom end of the upper bracket 4 is movably connected to a lower bracket 5. The outer side of the lower bracket 5 is provided with a storage groove 11 that can accommodate the upper bracket 4. The bottom end of the upper bracket 4 is slidably connected to the storage groove 11 and can rotate. That is, the upper bracket 4 can have the function of telescopic relative to the lower bracket 5, and the bottom end of the upper bracket 4 can rotate relative to the lower bracket 5, so that there is a folding function between the upper bracket 4 and the lower bracket 5. Through the relative telescopic of the upper bracket 4 and the lower bracket 5, the height adjustment effect can be achieved. The bottom end of the lower bracket 5 is hinged to a base 6, and the lower bracket 5 can rotate relative to the base 6, so that the upper bracket 4 and the lower bracket 5 can be folded on the top side of the base 6, so that it occupies less space and is easier to store.

[0027] The upper support 4 and the lower support 5 have a folded state and an unfolded state. When the upper support 4 and the lower support 5 are in the folded state, the upper support 4 and the lower support 5 are joined together on the top of the base 6.

[0028] Both the upper support 4 and the lower support 5 have slots 13 on their front sides. The bottom of the pull strip 3 has a hook assembly that can be hooked into the slot 13. By hooking the hook assembly into the slot 13 at the corresponding position, the length of the background cloth 2 can be determined.

[0029] Please see Figures 1 to 6The bottom of the upper bracket 4 is semi-circular, and the middle of the rear side of the lower bracket 5 is provided with an extension groove 8 that communicates with the placement groove 11.

[0030] A connecting cylinder 16 is fixedly installed at the center of the semi-circular bottom end of the upper support 4. When the upper support 4 is folded relative to the lower support 5, it rotates around the connecting cylinder 16 as the pivot. One end of the connecting cylinder 16 is slidably connected to the outer groove 8, allowing the connecting cylinder 16 to slide. This enables the upper support 4 and the lower support 5 to have the functions of extension, retraction, and folding. A bolt 7 is connected to the connecting cylinder 16 off-center. The bolt 7 abuts against the rear side of the lower support 5. By offsetting the bolt 7 from the center of the connecting cylinder 16, the bolt 7, after limiting the rotation of the upper support 4 around the connecting cylinder 16, will block the rotation, allowing the upper support 4 and the lower support 5 to maintain a relatively vertical state, thus making the support more stable.

[0031] Vertical stability is maintained by damping between the lower support 5 and the base 6, or by tightening bolts at the hinge points of the upper support 4 and the winding drum 1, and the hinge points of the lower support 5 and the base 6.

[0032] Please see Figures 1 to 6 The inner side of the storage groove 11 is provided with a sliding groove 12 opposite to the outer extension groove 8. The other end of the connecting cylinder 16 is slidably connected in the sliding groove 12, so that the bottom end of the hook 14 is more stably located in the lower support 5 for operation.

[0033] Please see Figures 1 to 6 The hook assembly includes a hook 14, which is L-shaped. One end of the hook 14 is slidably connected to the bottom of the pull bar 3. The hook 14 can move relative to the pull bar 3 so that the hook 14 can fit into the slot 13 on the upper bracket 4 or the lower bracket 5 and be placed therein for hanging. The other end of the hook 14 is hook-shaped and is placed in the slot 13.

[0034] A linear spring 15 is connected to the side of the hook 14 opposite to the hook-shaped end. One end of the linear spring 15 is connected to the pull bar 3. Through the elastic force of the linear spring 15, the hook 14 can extend into the slot 13, so that it can be stably hung.

[0035] Please see Figures 1 to 4 The inside of the take-up drum 1 is hollow, and a take-up roller 9 is rotatably connected inside the take-up drum 1. The top end of the background cloth 2 extends into the inside of the take-up drum 1 and is connected to the take-up roller 9. Through the rotation of the take-up roller 9, the background cloth 2 can be smoothly wound inside the take-up drum 1.

[0036] Please see Figures 1 to 4Torque springs 10 are installed on the outer sides of both ends of the take-up roller 9. One end of the torsion spring 10 is installed on the inner wall of the take-up drum 1. Through the rebound of the torsion spring 10, the take-up roller 9 can automatically rewind the background cloth 2, so that the background cloth 2 can be stably stored in the take-up drum 1.

[0037] In summary, when using this conference and exhibition display rack, the upper support 4 and the lower support 5 are rotated to make them vertical. Then, the position of the upper support 4 inside the storage groove 11 is adjusted to adjust the relative extension length of the upper support 4 and the lower support 5, thereby adjusting the height. Then, by installing bolts 7, the position of the upper support 4 after adjustment is limited by the contact between the bolts 7 and the lower support 5. Then, the pull bar 3 is pulled to release the background cloth 2 from the take-up roller 9. Then, by installing hooks 14 in the corresponding slots 13, the hooks 14 can be hooked by the pull bar 3, so that the background cloth 2 can be displayed smoothly.
