Description

Technical Field

[0001] This utility model relates to the field of advertising device technology, and in particular to an advertising device that is easy to temporarily fix. Background Technology

[0002] With social development, there is an increasing emphasis on people's spiritual and cultural needs, and many propaganda boards on ideological and political education can be seen everywhere in parks, subways, and other high-traffic areas. However, existing propaganda boards are generally integrated units, occupying a large area and being difficult to move once fixed in place, resulting in poor practicality.

[0003] For example, patent document CN214671631U discloses a political and ideological propaganda board, including a propaganda frame and a transparent cover. The transparent cover is movably connected to the front of the propaganda frame. Multiple insert rods are fixed to the side of the transparent cover near the propaganda frame. Multiple insertion holes are provided on the propaganda frame to engage with the insert rods. A permanent magnet is embedded in each insert rod, and an electromagnet is embedded in each insertion hole to cooperate with the permanent magnet. A handle is fixed to the side of the transparent cover away from the propaganda frame. A rain cover is provided at the top of the propaganda frame. A battery is installed at the rear of the propaganda frame, and the battery is electrically connected to the electromagnet. A power supply mechanism for providing power to the battery is installed on the rain cover. This invention effectively avoids the shortcoming of existing propaganda boards where the shaking of the cover can easily injure staff when updating posters.

[0004] In actual use, the aforementioned bulletin boards are relatively lightweight and are usually fixed in place by adhesive. However, since they are assembled into a whole, they take up a large area when used temporarily and cannot be moved flexibly or adjusted for suitability. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a convenient, temporarily fixed advertising device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A temporary advertising device includes two bases, each with a T-shaped groove at its top. A T-shaped column is rotatably connected to the inner wall of each T-shaped groove. A rotating disk is fixedly connected to the top of each T-shaped column. A vertical rod is fixedly connected to the top of each rotating disk. A vertical sleeve is slidably fitted onto the outer wall of each vertical rod. Threaded holes are formed on the outer wall of each vertical sleeve. Locking bolts are threaded onto the inner wall of each threaded hole. A first circular sleeve is fixedly connected to the bottom outer wall of each vertical sleeve. A metal rod is slidably fitted onto the inner wall of each first circular sleeve. A display mechanism is provided on the outer wall of each vertical sleeve.

[0008] Preferably, the display mechanism includes nylon fabric, with mounting holes at the top of the two vertical sleeves, fastening bolts threaded onto the inner walls of the two mounting holes, washers slidably fitted onto the outer walls of the two fastening bolts, and second circular sleeves fixedly connected to the outer walls of the two washers. The inner walls of the two second circular sleeves respectively contact the tops of the two metal rods, and the two ends of the nylon fabric are fixedly connected to the outer walls of the two metal rods respectively. A transparent plastic film is fixedly connected to the top outer wall of the nylon fabric. The nylon fabric is wound and unwound by setting up the display mechanism.

[0009] Preferably, multiple ball bearings are installed between the rotating disk and the base. The multiple ball bearings facilitate mutual rotation between the base and the rotating disk. However, after the nylon cloth is straightened, the rotating disk is limited by the overall length of the nylon cloth and cannot rotate.

[0010] Preferably, one end of each of the two locking bolts is rotatably connected to an arc-shaped piece, which is pressed against the vertical rod, thereby fixing the vertical sleeve to the vertical rod.

[0011] Preferably, the fastening bolt and the washer are pressed together, and the washer is pear-shaped as a whole.

[0012] Preferably, the outer wall of the transparent plastic film is fixedly inlaid with Velcro, and the outer surface of the nylon fabric has a fleece side that works in conjunction with the hook side of the Velcro. The fibers of the nylon fabric are tightly arranged, making it difficult for water to penetrate the fabric surface, thereby playing a certain role in waterproofing.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] This solution allows for easy carrying and movement of the entire unit by rotating one of the vertical sleeves to roll up the nylon fabric and transparent plastic film. The poster is positioned between the transparent plastic film and the nylon fabric, with the transparent plastic film covering the outer surface of the poster for waterproofing. Releasing the fixing of the vertical poles allows for adjustment of the display height of the nylon fabric and the poster. Simultaneously, releasing the fixing of the two metal rods facilitates maintenance of the nylon fabric, enhancing both ease of use and overall versatility. Attached Figure Description

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Depend on Figures 1-5 As shown, a publicity device that is easy to temporarily fix includes two bases 1. The top of each base 1 is provided with a T-shaped groove. The inner wall of each T-shaped groove is rotatably connected to a T-shaped post 2. The top of each T-shaped post 2 is fixedly connected to a rotating disk 3. Multiple balls are installed between the rotating disk 3 and the base 1. The rotating disk 3 rotates through the T-shaped post 2 and the T-shaped groove, and the multiple balls assist the rotating disk 3 in rotating.

[0024] The tops of the two rotating disks 3 are fixedly connected to vertical rods 4. The outer walls of the two vertical rods 4 are slidably fitted with vertical sleeves 5. The vertical sleeves 5 move up and down through the vertical rods 4. The outer walls of the two vertical sleeves 5 are threaded holes. The inner walls of the two threaded holes are threaded with locking bolts 6. One end of the two locking bolts 6 is rotatably connected to an arc-shaped piece 7. The arc-shaped piece 7 is pressed against the vertical rod 4. One end of the locking bolt 6 is fixedly fitted with a bearing. The outer ring of the bearing is fixedly connected to the outer wall of the arc-shaped piece 7.

[0025] The bottom outer walls of the two vertical sleeves 5 are fixedly connected with the first circular sleeves 8, and the inner walls of the two first circular sleeves 8 are slidably fitted with metal rods 9. The first circular sleeves 8 cooperate with the second circular sleeves 11 to limit the position of the metal rods 9.

[0026] The outer wall of the vertical sleeve 5 is provided with a display mechanism, which includes nylon cloth 13. The top of both vertical sleeves 5 is provided with mounting holes, and the inner wall of both mounting holes is threaded with fastening bolts 12. The fastening bolts 12 and washers 10 are pressed together, and the screw head of the fastening bolts 12 is pressed against the top of the washers 10 to fix the position of the washers 10.

[0027] Washers 10 are slidably fitted on the outer walls of the two fastening bolts 12, and second round sleeves 11 are fixedly connected to the outer walls of the two washers 10. The inner walls of the two second round sleeves 11 are in contact with the tops of the two metal rods 9 respectively.

[0028] The two ends of the nylon cloth 13 are fixedly connected to the outer walls of the two metal rods 9 respectively. A transparent plastic film 14 is fixedly connected to the top outer wall of the nylon cloth 13. The transparent plastic film 14 can be made of PVC material. A Velcro 15 is fixedly embedded on the outer wall of the transparent plastic film 14.

[0029] Working principle: When carrying, move one base 1 closer to the other base 1, then rotate the vertical sleeve 5 to drive one of the metal rods 9 to rotate. The metal rod 9 rotates around the rotating disk 3, rolling the nylon cloth 13 and the transparent plastic film 14 onto the rotating vertical sleeve 5. After rolling, the two vertical sleeves 5 are close to each other, making it easy to carry and move the whole thing. When using temporarily, move one base 1 away from the other base 1, unfold the nylon cloth 13 and straighten it. When supporting, the poster is supported by the two bases 1. The poster is then attached to the transparent plastic film 14 and the nylon cloth 13 with existing double-sided tape. The transparent plastic film 14 is attached to the nylon cloth with two Velcro straps 15. On 13, tearing off the Velcro 15 allows the bottom of the transparent plastic film 14 to open, which covers the outer surface of the poster and serves as a waterproof layer. Rotating the two locking bolts 6 moves the two arc-shaped pieces 7 outward, so that the arc-shaped pieces 7 no longer press against the outer wall of the vertical rod 4, allowing the vertical sleeve 5 to move up and down through the vertical rod 4, thus adjusting the display height of the nylon cloth 13 and the poster. When it is necessary to replace the nylon cloth 13, rotate the two fastening bolts 12 to disengage it from the two mounting holes, remove the two washers 10 and the two second round sleeves 11 from the top of the vertical sleeve 5, release the position fixation of the two metal rods 9, and remove the bottom of the two metal rods 9 from the inside of the two first round sleeves 8, thus completing the disassembly of the nylon cloth 13 and subsequent maintenance.
