Abstract
Description
Technical Field
[0001] This utility model relates to the field of billboard technology, and in particular to a billboard with a detachable frame structure. Background Technology
[0002] Billboards are a general term for all outdoor media that convey advertising information. The size of the media depends on the actual environment. They are large visual media set up in outdoor public places to display commercial information, brand image or public service announcements. With their huge size, eye-catching location, strong visual impact and wide audience coverage, they have become an important channel for brand communication and play a key role in urban landscape and commercial communication.
[0003] Most existing billboard frames use welded or bolted non-removable structures, which makes transportation, installation and subsequent maintenance cumbersome and inefficient. A lot of time is spent tightening screws during disassembly and installation, which seriously affects work efficiency. In addition, the installation and disassembly of existing billboards are quite complicated.
[0004] Therefore, those skilled in the art have provided a billboard with a detachable frame structure to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a billboard with a detachable frame structure. By manually rotating the screw and utilizing the cooperation of the inclined groove and the locking block, tool-free quick disassembly and installation can be achieved, simplifying the operation process, shortening the disassembly and installation time, improving work efficiency, and reducing labor costs.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A billboard with a detachable frame structure includes a mounting frame and two mounting columns. The lower end of the mounting frame is provided with a disassembly mechanism. The disassembly mechanism includes a screw rod, a fixing plate rotatably mounted on the upper end of the screw rod, connecting rods fixedly mounted on the lower ends of both sides of the fixing plate, fixing blocks fixedly mounted on the lower ends of the two connecting rods, two inclined grooves opened at the rear ends of the two fixing blocks, and locking blocks slidably mounted on the outside of the multiple inclined grooves.
[0008] The lower end of the mounting frame is rotatably provided with a bidirectional lead screw, and the external thread of the bidirectional lead screw is connected to two connecting plates. The rear ends of the two connecting plates are slidably provided with pressure plates.
[0009] Furthermore, two connecting columns are fixedly provided at the lower end of the mounting frame, and the two connecting columns are externally located at the upper end of the two mounting columns. A protective cover is hinged to the lower end of the mounting frame.
[0010] Furthermore, the lower outer end of the screw is located inside the protective cover, the screw is externally threadedly connected to the lower inner end of the mounting frame, and the fixing plate is externally slidably located at the lower inner end of the mounting frame.
[0011] Furthermore, the two fixing blocks are slidably disposed on the outside of the two connecting columns, and the multiple locking blocks are slidably disposed on the outside of the two connecting columns, with each pair of locking blocks disposed on opposite sides inside the two mounting columns.
[0012] Furthermore, multiple springs are fixedly installed at the front ends of both pressure plates, and the front ends of the multiple springs are respectively fixedly installed inside the front ends of the two connecting plates.
[0013] Furthermore, both ends of the two connecting plates are slidably disposed inside the mounting frame, and the rear ends of the two pressure plates are disposed inside the mounting frame.
[0014] Furthermore, a turntable is fixedly installed on one side of the bidirectional lead screw, and a glass door is hinged to the front end of the mounting frame.
[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model proposes an advertising billboard with a detachable frame structure. When disassembling the billboard frame, the fixing plate slides down inside the mounting frame by rotating the screw. The connecting rods on both sides of the fixing plate drive the fixing block to move down inside the connecting column, causing the locking blocks to slide towards each other inside the connecting column. This allows the locking blocks to completely disengage from the slots inside the mounting column, thereby releasing the locking state between the mounting frame and the mounting column. The frame can be quickly disassembled and installed by rotating the screw, shortening the operation time, improving work efficiency, and reducing the cost and difficulty of manual maintenance.
[0017] 2. The present invention proposes an advertising billboard with a detachable frame structure. When installing the contents of the advertising billboard, rotating the turntable causes the two connecting plates to move closer to the middle. The pressure plate slidably set at the rear end of the connecting plate gradually generates a pressing force on both sides of the advertising billboard under the action of the spring. The spring can ensure that advertising billboards of different thicknesses can be fixed in the installation frame by the pressure plate. This not only simplifies the installation and disassembly process of the advertising billboard, but also increases the adaptability to advertising billboards of different thicknesses and sizes.

[0027] 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.
[0028] Reference Figures 1-5 One embodiment provided by this utility model:
[0029] A billboard with a detachable frame structure includes a mounting frame 1 and two mounting columns 4. The lower end of the mounting frame 1 is provided with a disassembly mechanism 3. The disassembly mechanism 3 includes a screw 304. A fixing plate 305 is rotatably provided on the upper end of the screw 304. Connecting rods 306 are fixedly provided on both lower ends of the fixing plate 305. Fixing blocks 308 are fixedly provided on the lower ends of the two connecting rods 306. Two inclined grooves 307 are opened at the rear ends of the two fixing blocks 308. A locking block 303 is slidably provided on the outside of the multiple inclined grooves 307.
[0030] Two connecting posts 302 are fixedly installed at the lower end of the mounting frame 1. The two connecting posts 302 are externally installed inside the upper end of the two mounting posts 4. A protective cover 301 is hinged at the lower end of the mounting frame 1. The lower end of the screw 304 is externally installed inside the protective cover 301. The screw 304 is externally threadedly connected to the lower end of the mounting frame 1. A fixing plate 305 is externally slidably installed inside the lower end of the mounting frame 1. Two fixing blocks 308 are externally slidably installed inside the two connecting posts 302. Multiple locking blocks 303 are externally slidably installed inside the two connecting posts 302. The multiple locking blocks 303 are arranged on opposite sides inside the two mounting posts 4.
[0031] Specifically, during the dismantling of the billboard frame, the operator first uses a key to open the protective cover 301 at the bottom of the mounting frame 1, exposing the screw 304 inside. Then, by rotating the screw 304, which engages with the threaded connection on the inner side of the bottom of the mounting frame 1, the screw 304 moves downwards under the action of the threaded transmission mechanism. The top of the screw 304, through a rotating connection, pulls the fixing plate 305, causing it to slide down inside the mounting frame 1. The connecting rods 306 fixedly connected to the lower sides of the fixing plate 305 will drive the fixing blocks 308 to move downwards simultaneously, causing... The fixing block 308 slides sequentially inside the connecting column 302. During the downward movement, the inclined groove 307 at the rear end of the fixing block 308 generates an oblique traction force on the sliding block 303 located on its outer side. The oblique thrust provided by the inclined groove 307 causes the block 303 to move relative to the connecting column 302 and retract inward. As the block 303 continues to retract and gradually disengages from the groove inside the mounting column 4, the locking state between the mounting frame 1 and the mounting column 4 is released, thus successfully completing the separation of the mounting frame 1 and the mounting column 4. Subsequently, the disassembly of the mounting frame 1 can be completed.
[0032] During installation, the operator must first precisely align the connecting column 302 at the lower end of the mounting frame 1 and insert it into the fixing hole at the upper end of the mounting column 4. Then, rotate the screw 304 in the opposite direction to drive the fixing plate 305 to move upward, thereby causing the fixing block 308 to rise accordingly. The direction of the pushing force of the inclined groove 307 on the locking block 303 changes accordingly, causing the locking block 303 to expand outward and re-lock into the locking grooves on both sides of the mounting column 4, thereby achieving a stable connection between the mounting frame 1 and the mounting column 4 and ensuring the stability and safety of the billboard frame.
[0033] Traditional billboards often require multiple tools to remove a large number of screws during disassembly, which is cumbersome and time-consuming. However, the disassembly mechanism 3 of this billboard, through the rotation of the screw 304 and the cooperation of the inclined groove 307 and the locking block 303, achieves tool-free quick disassembly and installation, simplifying the operation process, shortening the disassembly and installation time, improving work efficiency, and reducing labor costs. At the same time, it reduces the use of screws, avoiding problems such as screw loss and stripping, further improving the reliability of disassembly and installation. Meanwhile, the protective cover 301 at the lower end can effectively protect the screw 304 of the disassembly mechanism 3, and the sealing ring at the upper end of the protective cover 301 can prevent dust and rainwater from entering, reduce the wear and corrosion of parts, and extend the service life of the billboard.
[0034] Reference Figures 1-7 The lower end of the mounting frame 1 is rotatably equipped with a two-way screw 8. The two-way screw 8 is externally threaded to two connecting plates 9. The rear ends of the two connecting plates 9 are slidably equipped with pressure plates 5.
[0035] Multiple springs 6 are fixedly installed at the front ends of the two pressure plates 5. The front ends of the multiple springs 6 are respectively fixedly installed inside the front ends of the two connecting plates 9. The upper and lower ends of the two connecting plates 9 are slidably installed inside the mounting frame 1. The rear ends of the two pressure plates 5 are both installed inside the mounting frame 1. A turntable 7 is fixedly installed on one side of the bidirectional screw 8. A glass door 2 is hinged at the front end of the mounting frame 1.
[0036] Specifically, when installing the billboard inside the mounting frame 1, the operator first opens the glass door 2 at the front of the mounting frame 1 with a key, and then rotates the turntable 7. The turntable 7 drives the bidirectional lead screw 8, which is fixedly connected to it, to rotate inside the mounting frame 1. Since the bidirectional lead screw 8 is connected to the two connecting plates 9 by threads, and the threads at both ends of the lead screw are opposite, when the lead screw rotates, the two connecting plates 9 will move closer or further away from each other along the axis of the bidirectional lead screw 8. When fixing the billboard, the operator rotates the turntable 7 to move the two connecting plates 9 towards the center. When the connecting plates 9 drive the pressure plate 5 to move to the appropriate position, the pressure plate 5 will squeeze the two sides of the billboard, causing it to slide forward inside the connecting plate 9. The opposite side of the pressure plate 5 is inclined. The pressure plate 5 will clamp the billboards of different thicknesses under the action of the spring 6, thereby achieving a stable fixation of the billboard.
[0037] When the content of the billboard needs to be changed, the operator only needs to rotate the turntable 7 in the opposite direction to move the connecting plate 9 to both sides. Under the action of the spring 6, the connecting plate 9 moves in the opposite direction, and the pressure plate 5 will release the clamping between the two sides of the billboard. Then, the operator can take out the billboard inside the installation frame 1, which improves the convenience of billboard replacement. The front glass door 2 can protect the billboard inside the installation frame 1. The rear end of the glass door 2 is equipped with a sealing strip to prevent environmental corrosion and improve the protective performance of the billboard.
[0038] Compared to traditional fixing methods, such as adhesive bonding or simple slot fixing, this device can not only firmly fix the billboard, but also prevent it from loosening or falling off under the influence of external environmental factors such as wind and vibration. It can also adapt to billboards of different thicknesses and materials, making it more widely applicable and ensuring the stability and durability of the billboard display effect. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0039] Working principle: When the billboard frame needs to be disassembled, the operator first uses a key to open the protective cover 301 hinged to the lower end of the mounting frame 1, exposing the screw 304. Then, by rotating the screw 304, since the screw 304 is threadedly connected to the lower end of the mounting frame 1, the screw 304 moves downward under the action of the threaded transmission. The fixing plate 305, which is rotatably set at the upper end of the screw 304, slides downward inside the mounting frame 1. The connecting rods 306 fixed at the lower ends of both sides of the fixing plate 305 will drive the fixing block 308 synchronously. As the device slides down, the fixing block 308 will slide downward inside the connecting column 302. During the descent, the inclined groove 307 at the rear end of the fixing block 308 generates an inclined thrust on the locking block 303 that is slidably set outside it, causing the locking blocks 303 to slide towards each other inside the connecting column 302, causing them to retract inward. As the locking blocks 303 retract, they will gradually disengage from the slot inside the mounting column 4, thereby releasing the mounting frame 1 from the mounting column 4. Subsequently, the mounting frame 1 and the mounting column 4 can be separated, completing the disassembly operation.
[0040] During installation, first align the connecting post 302 at the lower end of the mounting frame 1 with and insert it into the fixing hole at the upper end of the mounting post 4. Then, rotate the screw 304 in the opposite direction so that the screw 304 drives the fixing plate 305 to rise, and the fixing block 308 rises accordingly. The direction of the pushing force of the inclined groove 307 on the locking block 303 changes, causing the locking block 303 to slide outward and re-lock into the locking grooves on both sides inside the mounting post 4, thereby firmly connecting the mounting frame 1 and the mounting post 4.
[0041] When installing the billboard inside the mounting frame 1, the operator first opens the glass door 2 at the front of the mounting frame 1 with a key. Then, the operator rotates the turntable 7, which drives the bidirectional lead screw 8 fixedly connected to it to rotate inside the mounting frame 1. This causes the two connecting plates 9 to move relative to each other. The pressure plate 5, which is slidably set at the rear end inside the connecting plate 9, will exert a pressing force on both sides of the billboard when the pressure plate 5 moves to a certain position under the action of the spring 6. The pressure plate 5 can fix the billboard inside the mounting frame 1. The elastic force provided by the spring 6 can adapt to billboards of different thicknesses to ensure the fixing effect.
[0042] When the billboard needs to be replaced, turntable 7 is rotated in the opposite direction, causing the two connecting plates 9 to move to both sides. Under the elastic force of spring 6, pressure plate 5 separates from both sides of the billboard, making it easy to remove and replace the billboard.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
