Description

Technical Field

[0001] The present invention relates to the technical field of advertising billboards, and in particular to an advertising billboard for marketing promotion. Background Art

[0002] Billboards used for marketing promotion, as an indispensable visual medium between brands and consumers, cleverly build a visual bridge in busy streets, commercial areas or specific display areas through their unique and creative designs that combine carefully selected patterns, eye-catching texts and bright colors. These billboards not only capture the attention of passers-by, but also more profoundly convey the core concept of the brand, the unique selling points of the products and current promotional information, effectively promoting the improvement of brand awareness, and helping companies expand their market share and achieve business goals.

[0003] In today's life, advertisements have become a ubiquitous cultural phenomenon. They penetrate into every corner of our daily lives in various forms, from the wonderful film and television advertisements on TV screens to the personalized information flow advertisements pushed accurately on social media; from the colorful large posters on the streets to the mobile media advertisements scrolling on buses and subways; to the product recommendations and coupon distribution on e-commerce platforms, advertisements reach and influence our consumption decisions and lifestyles in an all-round way through visual, auditory and even interactive experiences. They are not only a means for brands to disseminate information and shape their image, but also an important force to guide market trends and promote economic development.

[0004] At present, there are indeed some problems in the design and application of promotional billboards that cannot be ignored, especially in the two aspects of protecting advertising content and portability. The problems are particularly significant. These billboards usually use traditional materials and structural designs, which makes it difficult for them to effectively resist bad weather, environmental pollution, and physical damage, which makes the advertising content easily damaged, and has an adverse effect on the publicity effect. At the same time, many billboards are seriously lacking in portability due to their large and bulky size, as well as cumbersome and complicated installation and disassembly processes, which makes it extremely difficult to carry out publicity activities in multiple different locations. For this reason, the defects of existing promotional billboards in protecting advertising content and portability have become key factors limiting their widespread application and full play. Summary of the invention

[0005] The object of the present invention is to provide a billboard for marketing promotion to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A billboard for market promotion and publicity comprises a box body and a cover plate, a folding assembly is fixedly installed inside the box body, the folding assembly comprises a chassis, the chassis is arranged inside the box body, and the chassis is slidably connected to the box body, a first pull rod is fixedly installed on the upper middle end of the chassis, a second pull rod is slidably installed on the outer side of the first pull rod, a handle is fixedly installed on the upper end of the second pull rod, a fixing ring is rotatably installed on the side wall of the end of the second pull rod away from the handle, two fixing rods are symmetrically rotatably installed on both sides of the fixing ring, a display component is arranged on the upper end of the chassis, one end of the two fixing rods away from the fixing ring is rotatably connected to the display component, a side handle is fixedly installed on the side of the box body, a plurality of arc grooves are symmetrically opened at both ends of the first pull rod, two pull grooves are symmetrically opened on the side wall of the first pull rod, two pull strips are symmetrically slidably installed inside the second pull rod, and the two pull strips pass through the second pull rod to the middle of the handle, and a protrusion is fixedly installed on the bottom end of the two pull strips, which are plug-fitted with the arc groove; the cover plate is rotatably installed on the upper end of the box body, and a buckle is arranged on the upper end of the cover plate.

[0008] The above technical solution is adopted. In this solution, when the equipment is used, the staff first opens the buckle on the cover and flips the cover. At this time, the staff pulls the handle to pull out the chassis through the first pull rod and the second pull rod fixed thereto. Through the arc groove limiting the pull rod, the second pull rod drives the first pull rod to move upward synchronously, and at the same time drives the chassis upward. When the chassis reaches parallel with the upper surface of the box body, the handle is rotated with the first pull rod as the axis. At this time, the pull rod rotates to the position of the pull groove, the pull rod and the second pull rod move upward, and at the same time the fixed ring moves upward, driving one end of the fixed rod rotatably connected thereto to move upward, and making the fixed ring The other end of the rod moves to the side away from the fixed circle. When the bottom of the second pull rod moves to the upper part of the first pull rod, the handle is turned clockwise to prevent the second pull rod from sliding downward through the arc groove. At this time, the display component is in the expanded state. The staff puts the advertisement to be displayed on the display component, and then presses the handle downward to control the fixed rod to pull the display component back into the box. Through the setting of the folding component, it is retracted into the box during transportation, which makes it easy to carry and transport and fully utilizes the space to a certain extent. At the same time, folding and retracting can better protect the advertising content, and it can be unfolded to obtain a larger display area when in use.

[0009] A further improvement of the technical solution of the present invention is that a blocking block is fixedly installed on the arc groove, a switch plate is fixedly installed on the upper end of the pull bar, a spring is fixedly installed on the upper end of the switch plate, and the upper end of the spring is fixedly connected to the lower end of the handle.

[0010] The above-mentioned technical solution is adopted. Through the setting of the resistance block in the arc groove, the folding component can be moved upward by pressing the protrusion at the bottom of the switch plate pull strip when in the unfolded state and the closed state. At this time, the second pull rod can be rotated. Such a setting avoids accidental operation that causes the component to be unfolded or closed during use, improves the safety of use, ensures that the state conversion of the folding component can be achieved only under specific operations, makes the control more precise, ensures the reliable working state of the folding component, reduces unnecessary actions caused by accidental touch, and maintains the stability of the component.

[0011] A further improvement of the technical solution of the present invention is that a limiting block is fixedly installed on the inner side of the upper end of the box body.

[0012] By adopting the above-mentioned technical solution, by installing a limit block on the upper end of the box, the chassis can be more accurately blocked and limited during its upward movement, ensuring that the movement of the chassis is within a controllable range, thereby effectively improving the stability and reliability of the entire device. This precise limit can also ensure that the chassis stops at a suitable position to avoid deviation or instability, thereby ensuring the effect and quality of the advertising display. At the same time, this also helps to reduce various problems and failures that may be caused by inaccurate chassis position.

[0013] A further improvement of the technical solution of the present invention is that a limit strip is installed at the bottom of the second pull rod, a slot is provided at the upper end of the limit strip, the slot is plugged into the pull rod, and a ball is rotatably installed at one end of the limit strip away from the first pull rod.

[0014] The above-mentioned technical solution is adopted, in which a limit strip is set, and the protrusion at the lower end of the pull strip is inserted into the slot. During the rotation of the second pull rod, the pull strip drives the limit strip to rotate, and the end away from the first pull rod is inserted into the groove on the inner wall of the upper end of the box body, thereby effectively enhancing the stability of the structure and preventing the first pull rod from loosening or sliding downward during the display process.

[0015] A further improvement of the technical solution of the present invention is that a base is fixedly installed at the lower end of the box body, and a universal caster is fixedly installed on the base.

[0016] The above technical solution is adopted, which makes the whole device have better flexibility and can be easily pushed to different positions to meet various usage requirements. Whether indoors or outdoors, the universal casters can allow the device to turn and move flexibly. Secondly, it greatly reduces the burden of transportation and improves work efficiency. At the same time, it can adapt to various ground environments and ensure the stability and safety of the device during movement.

[0017] A further improvement of the technical solution of the present invention is that telescopic rods are symmetrically rotatably installed at both ends of the base, the two telescopic rods can be telescopically arranged, pull rod handles are fixedly installed on the upper ends of the two telescopic rods, circular grooves are opened on the upper ends of the two pull rod handles, circular blocks are symmetrically fixedly installed on the two cover plates, and the circular grooves are plug-in-matched with the circular blocks.

[0018] By adopting the above technical solution, the telescopic rod is set, which can be more convenient to carry during transportation. At the same time, the cover can be stably placed on the telescopic rod through the plug-in cooperation between the circular groove and the circular block. Such a setting can not only display the advertising content, but also conveniently display the real objects, enrich the promotional form, and the audience can place their personal belongings more easily, thereby improving their favorability towards the promotional activities.

[0019] A further improvement of the technical solution of the present invention is that two clamping blocks are fixedly installed on both sides of the box body, and the two clamping blocks are clamped and connected with the telescopic rod.

[0020] The above technical solution is adopted, which makes the opening and closing operation of the telescopic rod more convenient and smooth. The telescopic rod is connected with the cover by a clip, ensuring that the cover can be stably maintained in the corresponding position when opening or closing, and is not easy to shake or loosen, making the entire device structure more compact and firm.

[0021] A further improvement of the technical solution of the present invention is that display windows are provided on the side surfaces of the display component and the side surfaces of both sides of the box body, and glass partitions are fixedly installed on the display windows.

[0022] The above technical solution is adopted, in which display windows are opened on the sides of the folding components, and the display windows are fixedly installed with glass partitions, which can clearly present advertisements to the target audience from multiple angles, thereby increasing the visibility and attractiveness of the advertisements. The presence of the glass partitions can not only effectively protect the displayed advertising content from external factors, but also keep the display area clean and beautiful. At the same time, the audience can clearly see the advertising content through the glass partitions, thereby improving the viewing experience. In addition, this setting method also facilitates the replacement and maintenance of advertisements, improves the practicality and convenience of the entire display component, and brings better results for advertising.

[0023] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0024] 1. The present invention provides a billboard for market promotion and publicity. Through the setting of a folding component, the billboard can be retracted into a box during transportation, thereby achieving the advantages of being easy to carry and transport and making full use of space to a certain extent. The folding and retraction can better protect the advertising content, and the billboard can be unfolded to obtain a larger display area when in use. In addition, through the setting of a resistance block in the arc groove, the folding component can be moved upward by pressing the protrusion at the bottom of the switch plate pull bar when in the unfolded state and the closed state, and the second pull rod can be rotated at this time. Such a setting avoids accidental operation during use that causes the component to be unfolded or closed, improves the safety of use, ensures that the state conversion of the folding component can be achieved only under specific operations, and makes the control more precise, ensuring the reliable working state of the folding component, reducing unnecessary actions caused by accidental touches, and maintaining the stability of the component.
