[0002] With increasing awareness of fire safety, the popularization and promotion of fire safety knowledge has become a key focus for all sectors of society. Whether in public places, schools, communities, or businesses, it is necessary to regularly hold fire safety knowledge promotion activities to raise public awareness and reduce the occurrence of fire accidents. Traditional methods of fire safety knowledge promotion mainly rely on posters, brochures, and lectures. While these methods have played a role to some extent, they suffer from limited effectiveness, narrow coverage, and outdated information.

[0003] To address the aforementioned issues, fire safety awareness displays have emerged. These displays typically utilize electronic screens, projection equipment, or light boxes to showcase dynamic or static fire safety information, offering advantages such as effective dissemination, rapid information updates, and wide coverage. However, the promotion and application of these modern displays have also revealed some problems.

[0004] First, the purchase and maintenance costs of modern propaganda equipment are high, making it difficult for resource-limited regions or organizations to afford. Second, these devices are usually large in size, occupying a lot of space and making them inconvenient to transport and install. Especially in some temporary propaganda activities or remote areas, these large propaganda devices are often ineffective due to inconvenient transportation or site limitations.

[0005] Therefore, a fire safety knowledge promotion and display device is proposed to address the above problems. Utility Model Content

[0030] Example:

[0031] Please see Figure 1-4 A fire safety knowledge publicity and display device for fire protection includes a box-type base 1 and a rolling rod 11. The box-type base 1 has a fixed shaft 2 fixedly connected to the inside near the left and right sides. The fixed shaft 2 has a bottom rod 3 slidably installed on the outside. The bottom rod 3 has a positioning hole 4 near the middle of the bottom end. The box-type base 1 has a fixing member 5 fixedly installed on the inner bottom near the fixed shaft 2. The fixing member 5 has a positioning rod 6 slidably installed through the middle of the fixing member 5. The positioning rod 6 and the positioning hole 4 are compatible. The bottom rod 3 has a secondary rod 9 slidably installed at the end away from the fixed shaft 2. The bottom rod 3 and the secondary rod 9 have a socket 12 at the ends away from each other. The socket 12 is compatible with the rolling rod 11. The rolling rod 11 has a fire protection illustration groove 13.

[0032] Compared to traditional advertising racks, this solution greatly reduces the space required by designing the base rod 3, secondary rod 9, and roll rod 11 to be stored inside the box-shaped base 1, while also providing protection. When transported to the advertising site, the square box-shaped base 1 can be neatly arranged in the vehicle compartment. When more advertising racks are needed, more goods can be carried in the limited transport compartment.

[0033] Please see Figure 4 The positioning rod 6 has fixing holes 7 near both ends, and fixing pins 8 are slidably inserted into the middle of the upper end of the fixing part 5. The fixing pins 8 and fixing holes 7 are compatible.

[0034] By rotating the bottom rod 3, it can be removed from the inside of the slot 16. When rotated to the vertical position, the bottom rod 3 is slid to move it to the middle position of the fixed shaft 2, thereby moving the positioning rod 6 to pass through the positioning hole 4. Then, the fixing pin 8 is inserted into the inside of the fixing part 5 and passes through the fixing hole 7, thus completing the fixing of the positioning rod 6. At the same time, the positioning rod 6 also plays a role in limiting and fixing the bottom rod 3.

[0035] Please see Figure 2 Fasteners 10 are provided on the bottom rod 3 at one end near the second rod 9;

[0036] The output height of the secondary rod 9 can be adjusted by tightening or loosening the fastener 10, thus adapting to different sizes of promotional paper and making it more reasonable.

[0037] Please see Figure 1-2 The left and right ends of the box-type base 1 are provided with two sets of symmetrical storage holes 14 near the upper side. There are two sets of scroll rods 11, which pass through and slide between the storage holes 14 at the left and right ends respectively.

[0038] The scroll rod 11 can be hidden through the storage hole 14. When loading or unloading goods or moving to a specific site, the staff can lift and move the device by holding the scroll rod 11, which is very convenient and effectively improves work efficiency.

[0039] Please see Figure 4 The left and right ends of the box base 1 are provided with combination holes 15 at the corresponding positioning rods 6, and the combination holes 15 are adapted to the positioning rods 6.

[0040] By further inserting the positioning rod 6 through the combination hole 15 on another set of box-type bases 1 and into the positioning hole 4 on the bottom rod 3 inside the box-type base 1, the bottom rod 3 of the set is fixed and positioned. The positioning rod 6 is then fixed by passing the fixing pin 8 through the fixing hole 7, thus completing the connection and fixation between the two sets of box-type bases 1. When multiple advertising racks need to be placed side by side, this method not only makes the advertising racks neater and more beautiful, but also improves the stability between the advertising racks, effectively reducing the problem of easy tipping due to other reasons, and ensuring the advertising effect.

[0041] Please see Figure 1-4 The upper end of the fastener 5 is provided with a slot 16 near both the front and rear sides, and the slot 16 is compatible with the bottom rod 3 and the second-stage rod 9.

[0042] The base rod 3 and the secondary rod 9 are supported and fixed in a staggered manner by the slot 16, which avoids shaking and collision during transportation, thus preventing deformation and affecting use and ensuring the rationality of the structure.

[0043] Working Principle: Compared to traditional advertising stands, this solution significantly reduces the space required by housing the base rod 3, secondary rod 9, and coil rod 11 within the box-shaped base 1, while also providing protection. During transport to the advertising site, the square box-shaped base 1 allows for neat placement within the vehicle. When more advertising stands are needed, more goods can be carried within a limited transport space. Furthermore, during loading, unloading, or moving to a specific location, workers can easily lift and move the device by holding the coil rod 11, greatly improving work efficiency. In use, the coil rod 11 is pulled out from the storage hole 14, and then the two sets of coil rods 11 are inserted into the corresponding insertion holes 12 on the two sets of base rods 3 and secondary rods 9, respectively. Finally, the top and bottom ends of the promotional poster are passed through the fire illustration slots 13 on the two upper and lower roller rods 11, respectively. Then, the roller rods 11 are rotated to wind around the two ends of the promotional poster twice, thus fixing the promotional poster. In addition, by further inserting the positioning rod 6 through the combination hole 15 on another set of box-type bases 1 and into the positioning hole 4 on the bottom rod 3 inside the box-type base 1, the bottom rod 3 of the set is fixed and limited. The positioning rod 6 is fixed by passing the fixing pin 8 through the fixing hole 7, thus completing the connection and fixation between the two sets of box-type bases 1. When multiple promotional racks need to be placed side by side, this method not only makes the promotional racks more neat and beautiful, but also improves the stability between the promotional racks, effectively reducing the problem of easy tipping due to other reasons, and ensuring the promotional effect of the advertisement.

[0044] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
