Description

Technical Field

[0001] This invention belongs to the technical field of poster advertising, and specifically discloses a poster advertising device that intermittently cycles and switches. Background Technology

[0002] The core purpose of poster advertising is to efficiently convey information through visual means, attract the target audience, and promote brand or event communication. Posters, with their vibrant colors, images, and concise text, quickly capture the audience's attention in an information-saturated environment, achieving rapid delivery of core information. For example, promotional posters can visually display discount information, while event posters can quickly convey key information such as event time and location. Therefore, the content of the posters is often changed to ensure that different content is promoted sequentially. Chinese patent CN110767115A discloses a rotating poster display panel. However, in this design, the replacement frequency can only be timed according to the frequency of the driving device, making it inconvenient to adjust the replacement frequency based on the displayed content.

[0003] Compared to high-cost formats like television advertising, posters offer lower production costs and greater flexibility in design and distribution channels (such as online social media and offline billboards), making them suitable for targeted marketing by SMEs. Posters need to convey core information within a limited space, emphasizing intuitiveness and ease of understanding. Through concise combinations of text and images, they can quickly convey key information such as product features and event dates, avoiding information redundancy. However, existing posters, when used for cyclical promotion, present multiple posters as a whole. For example, in the aforementioned Chinese patent CN110767115A, posters are attached to a display cloth using an adhesive method to form a whole. If the content of a single poster needs to be changed, the entire poster needs to be reprinted, resulting in wasted resources and increased replacement costs. Summary of the Invention

This will move the replaceable promotional posters in the poster installation area to the corresponding positions on the protective display board for display.

[0017] 2. Determine the interval between displays based on the content of the poster, and adjust the number of top rods installed on the mounting base: the fewer the number of top rods, the fewer times the start button is touched and the longer the poster display time; the more top rods, the more times the start button is touched and the shorter the poster display time; when the installation of top rods is irregular, the number of times the start button is touched and the start time is also irregular, and the poster display time can be long or short.

[0018] 3. By removing and installing the fasteners on the poster installation area, replaceable promotional posters can be flexibly replaced. Removing the fasteners from the poster installation area makes it easy to take out and replace individual replaceable promotional posters with content that needs to be changed. Installing the fasteners on the poster installation parts can fix the new replaceable promotional poster after replacement. There is no need to re-wash and reprint the entire poster, which reduces resource waste and lowers replacement costs. Attached Figure Description

[0047] like Figure 1-3 As shown, this embodiment provides an intermittently cyclically switching poster advertising device, including a housing 1 and a poster display mechanism and a cyclic switching mechanism disposed within the housing 1; a transparent protective display panel 101 is provided on the front of the housing 1, and the protective display panel 101 is made of glass; as shown Figure 5-9As shown, the poster display mechanism includes a connecting roller 507 and a poster display belt; as Figure 14-19 As shown, the cycle switching mechanism includes a drive roller 601, a sprocket 602, a chain 603, a second mounting bracket 604, a start button 606, a first drive unit 608, a drive shaft 609, a push rod 611, a rotating disk 615, a push rod 618, and a second drive unit 620; at least two threading rollers 507 are provided, and the drive roller 601 has at least one more than the threading roller 507, such as... Figure 9 The intermediate connecting roller 507 has three sections, such as... Figure 14-15 The middle drive roller 601 is equipped with five rollers, such as... Figure 10 Two connecting rollers 507 and three drive rollers 601 are provided; the connecting rollers 507 are arranged in parallel and rotate above the protective display panel 101; the drive rollers 601 are arranged in parallel and rotate below the protective display panel 101; each drive roller 601 has a sprocket 602 installed at its end, and a chain 603 is sleeved on the sprocket 602; the poster display belt has multiple connecting belts 508 and multiple poster mounting areas 509 spaced apart, and the poster display belt passes through the connecting rollers 507 and drive rollers 601 in sequence and is connected end to end. The part of the poster display belt between the connecting rollers 507 and drive rollers 601 is parallel to the protective display panel 101; a start button 606 and a second drive unit 620 are installed on the second mounting frame 604; the second drive unit 620 is controlled by the start button 606 and is used for... The drive sprocket 602 rotates synchronously; the output end of the first drive unit 608 is connected to the drive shaft 609; the push rod 611 is perpendicularly connected to the drive shaft 609; the rotating disk 615 is rotatably connected to the second mounting bracket 604 and is located between the second mounting bracket 604 and the push rod 611; multiple mounting seats 619 are provided on the side of the rotating disk 615 facing the second mounting bracket 604, and the circle in which the multiple mounting seats 619 are located is concentric with the rotating disk 615; the start button 606 is located on the circle in which the multiple mounting seats 619 are located; the push rod 618 is installed on the mounting seat 619 and is used to press the start button 606; multiple push seats 616 are provided on the side of the rotating disk 615 facing the push rod 611, and the circle in which the multiple push seats 616 are located is concentric with the rotating disk 615, and any one of the push seats 616 is pushed to rotate by the push rod 611.

[0048] The working process of the above-mentioned poster advertising device is as follows:

[0049] During the intermittent cyclic display of posters, the first drive unit 608 is activated to drive the drive shaft 609 to rotate smoothly. When the drive shaft 609 rotates, the push rod 611 mounted on it rotates. After rotating one revolution, the push rod 611 will contact a single push seat 616, pushing the push seat 616 to rotate one unit. The rotating disk 615 then rotates on the second mounting bracket 604. When the intermittent time is reached, the top rod 618 mounted on the mounting bracket 619 will press the start button 606 to activate it. The second drive unit 620 receives the start signal and drives the sprocket 602 to rotate. The drive roller 601 and the chain 603 mounted on the sprocket 602 are driven at the same time. Multiple drive rollers 601 rotate synchronously, the poster display belt moves up and down, and the replaceable promotional posters 511 installed in the poster installation area 509 move to the corresponding position on the protective display plate 101 for display. Once the replaceable promotional poster 511 to be displayed is replaced, the push rod 611 rotates one full turn and contacts the next push seat 616. The push rod 618 rotates and separates from the start button 606, causing the start button 606 to lose its pressing force. The unpressed start button 606 cannot activate the second drive unit 620. The replaceable promotional poster 511 to be displayed will then be briefly displayed in the protective display panel 101. By repeating this cycle and adjusting according to the content displayed on the poster, the intermittent cyclical promotion of the replaceable promotional poster 511 can be completed.

[0050] The interval between displays is determined based on the content displayed on the replaceable promotional poster 511. The number of top rods 618 installed on the mounting base 619 is adjusted accordingly: the fewer the number of top rods 618, the fewer times the start button 606 is touched and activated, resulting in a longer display time for the replaceable promotional poster 511; the more the number of top rods 618, the more times the start button 606 is touched and activated, resulting in a shorter display time for the replaceable promotional poster 511; when the installation of top rods 618 is irregular, the number of times the start button 606 is touched and activated is also irregular, resulting in a variable display time for the replaceable promotional poster 511.

[0051] In this embodiment, the first drive unit 608 and the second drive unit 620 are motors.

The preset position is located on the line connecting the center of the C-ring 612 and the centers of the multiple push seats 616. The C-ring 612 rotates to bring the push seat 616 at the preset position into the C-ring 612 from the opening and make it fit against the push seat 616, thus limiting the push seat 616 at the preset position and preventing it from continuing to rotate. The connecting rod 610 stabilizes the C-ring 612 so that it rotates stably. The connecting rod 610 passes over the push seat 616 at the preset position during rotation without interfering with the push seat 616. At the same time as the push rod 611 pushes the next push seat 616 to the preset position, the push seat 616 at the preset position disengages from the opening of the C-ring 612.
