Description

Technical Field

[0001] The present invention relates to the technical field of signboards, and specifically to a multifunctional signboard for environmental art design. Background Art

[0002] A signboard, as the name implies, is a sign that indicates direction, and is also called a billboard or a signboard. For example, toilet direction signs, road signs, etc. can all be called signboards. Its definition is relatively broad. Lobby signboards, guide signs, room number plates, consultation desk signs, cashier desk signs for hotel and hotel supplies, plastic signs for parking, park reminder signs, etc. all belong to the category of signboards.

[0003] After retrieval, the publication number CN217521734U discloses a notice board, including a notice board formed by connecting a slogan board and a support rod through bolts; a support frame movably connected inside a through groove formed through the surface of the support rod, and a guiding groove is formed on the side surface of the support frame; a telescopic rod slidably connected inside the support rod, with a limiting plate fixedly installed at the upper end of the telescopic rod, sliding rods symmetrically arranged inside the limiting plate, and a cleaning member sleeved on the surface of the sliding rod for cleaning the soil inside the guiding groove. Through the coordinated use of each component, when the notice board is fixed and the telescopic rod contacts the ground, the notice board will drive the support rod to move downward under the action of gravity, causing the telescopic rod to enter the inside of the support rod, and the support frame will open under the action of the sliding rod and the guiding groove to assist in fixing the notice board, so that the notice board can remain stable in rainy and windy weather.

[0004] However, the above patent has the following problems: After long-term use, the surface of the signboard is prone to accumulate dust, stains and even graffiti, affecting the display effect and aesthetics. Especially in outdoor or public places, the maintenance and cleaning work is frequent and costly. In the prior art, some signboards adopt fixed display content and cannot meet the need for dynamic information update; while signboards that require scrolling display mostly rely on manual cleaning or simple mechanical cleaning devices, and the cleaning efficiency and effect are limited.

[0005] In view of the deficiencies of the prior art, the present invention designs a multifunctional signboard, which combines a transmission system and a cleaning device to achieve the dual functions of dynamic display of information and automatic cleaning, solves the pain points of traditional signboards in cleaning and maintenance, and improves the overall performance and user experience. Summary of the Invention

[0011] Preferably, one side of the side fixing plate is slidably provided with a bracket main body through a guide rod. A guide slot is formed on the surface of the bracket main body, and the guide slot is adapted to the guide rod. A contact wheel bracket is fixedly arranged on the surface of the bracket main body, and a contact wheel is rotatably arranged on the contact wheel bracket. A lower cleaning roller is rotatably arranged on one side of the bracket main body, and a first bevel gear is fixedly arranged on the shaft end of the lower cleaning roller. A support plate frame is fixedly arranged on the surface of the bracket main body. The rotating shaft is rotatably arranged on the support plate frame and the side fixing plate of the bracket main body, and a fourth bevel gear is fixedly arranged on the surface of one end of the rotating shaft. A second bevel gear is slidably arranged on the side of the rotating shaft away from the fourth bevel gear. The driving rotating roller and the lower rotating wheel on the inner linkage cleaning member are driven by a transmission belt. The rotation of the driving rotating roller drives the lower rotating wheel to rotate synchronously. The rotation of the lower rotating wheel drives the whole linkage rod to rotate. When the linkage rod rotates, it drives the rotating cam to rotate and at the same time drives the third bevel gear to rotate. The third bevel gear and the fourth bevel gear rotate to drive the rotating shaft to rotate. Subsequently, the second bevel gear rotates following it under the action of the rotating shaft. The second bevel gear meshes with the first bevel gear to drive the lower cleaning roller to rotate. The lower cleaning roller is in contact with the surface of the notice conveyor belt. At the same time, the rotating cam rotates to drive the contact wheel to rotate. The bracket main body and the side fixing plate are slidably connected to each other. The rotation of the rotating cam drives the bracket main body to reciprocate horizontally relative to the side fixing plate. At the same time, the bracket main body is reset under the action of the connecting spring member.

[0012] Preferably, the first bevel gear meshes with the second bevel gear, and the first bevel gear and the second bevel gear have the same specifications.

[0013] Preferably, the contact wheel meshes with the rotating cam on the linkage rod, and the rotating cam is eccentrically arranged on the linkage rod.

[0016] Preferably, the width value of the bracket main body is smaller than the diameter of the lower cleaning roller, and the length of the lower cleaning roller is adapted to the driving rotating roller.

[0017] Preferably, the usage method includes the following steps;

[0018] Step S1: Install the entire device in place. Through the mutual cooperation of the upper notice cover plate, the indication notice board, and the lower support plate on the support column, indicate the marked location, etc. An opening window is provided on the surface of the indication notice board. Through the rotation of the driving rotating roller inside the indication notice board, drive the notice conveyor belt to move and display the marks. At the same time, indication marking words are set on the surface of the indication notice board.

[0019] Step S2: The driving rotating roller and the lower rotating wheel on the internal linkage cleaning part are driven by a conveyor belt. Through the rotation of the driving rotating roller, drive the lower rotating wheel to rotate synchronously. The rotation of the lower rotating wheel drives the entire linkage rod to rotate. When the linkage rod rotates, it drives the rotating cam to rotate and at the same time drives the third bevel gear to rotate. The third bevel gear and the fourth bevel gear rotate, driving the rotating shaft to rotate. Subsequently, the second bevel gear rotates following it under the action of the rotating shaft. The second bevel gear meshes with the first bevel gear, driving the lower cleaning roller to rotate. By fixedly installing the support column, the lower support plate is fixed on the upper side of the support column. The lower support plate supports the indication notice board. The upper notice cover plate is clamped on the upper side of the indication notice board to protect the internal structure. An opening window is provided on the surface of the indication notice board to display the current information. The driving rotating rollers inside the indication notice board are arranged horizontally. The notice conveyor belt is driven to roll through the conveyor belt. The notice conveyor belt surrounds the driving rotating roller and rolls to display multiple segments of information, which is displayed through the opening window. The rotation of the driving rotating roller is transmitted to the lower rotating wheel of the internal linkage cleaning part through the conveyor belt, driving the linkage rod to rotate. The rotating cam eccentrically arranged on the linkage rod drives the contact wheel to move up and down, causing the bracket main body to translate left and right along the guide rod. At the same time, the third bevel gear meshes with the fourth bevel gear, driving the rotating shaft to rotate. The rotating shaft drives the lower cleaning roller to rotate through the second bevel gear and the first bevel gear. The lower cleaning roller contacts the surface of the notice conveyor belt and performs comprehensive cleaning through rotation and lateral sliding. The internal pump sucks the cleaning liquid from the storage tank and sprays it onto the surface of the notice conveyor belt through the internal spray head to soften the stains and enhance the cleaning effect. The connecting spring member pulls the bracket main body to reset when the cam disengages, ensuring the continuous cycle of the cleaning action.

[0020] The present invention provides a multifunctional sign for environmental art design. Compared with the prior art, it has the following beneficial effects:

The rotating shaft 66 is rotatably arranged on the support plate frame 65 on the bracket main body 61 and the side fixing plate 69, and a fourth bevel gear 68 is fixedly arranged on the surface of one end of the rotating shaft 66. A second bevel gear 64 is slidably arranged on the side of the rotating shaft 66 away from the fourth bevel gear 68. The first bevel gear 63 meshes with the second bevel gear 64, and the first bevel gear 63 and the second bevel gear 64 have the same specifications. After the whole device is installed in place, through the mutual cooperation and installation of the upper notice cover plate 1, the indicating notice board 2 and the lower support plate 3 on the support column 4, the indicating of the indicating location and the like is carried out. An opening window 5 is formed on the surface of the indicating notice board 2. Through the rotation of the driving rotating rollers 8 inside the indicating notice board 2, the notice rotating belt 7 is driven to move and display. At the same time, indicating marking words are arranged on the surface of the indicating notice board 2. The driving rotating rollers 8 and the lower rotating wheels 616 on the internal linkage cleaning members 6 are driven by a transmission belt 10. The rotation of the driving rotating rollers 8 drives the lower rotating wheels 616 to rotate synchronously. The rotation of the lower rotating wheels 616 drives the whole linkage rod 612 to rotate. When the linkage rod 612 rotates, it drives the rotating cam 613 to rotate and at the same time drives the third bevel gear 67 to rotate. The third bevel gear 67 and the fourth bevel gear 68 rotate to drive the rotating shaft 66 to rotate.Subsequently, the second bevel gear 64 rotates following the rotation of the rotating shaft 66. The second bevel gear 64 meshes with the first bevel gear 63, driving the lower cleaning roller 62 to rotate. The lower cleaning roller 62 contacts the surface of the notice conveyor belt 7. At the same time, the rotating cam 613 rotates, driving the contact wheel 611 to rotate. The bracket main body 61 is slidably connected to the side fixing plate 69. The rotation of the rotating cam 613 drives the bracket main body 61 to reciprocate and translate relative to the side fixing plate 69. At the same time, the bracket main body 61 is reset under the action of the connecting spring member 614.

[0036] The contact wheel 611 meshes with the rotating cam 613 on the linkage rod 612, and the rotating cam 613 is eccentrically arranged on the linkage rod 612. A transmission belt 10 is arranged inside the indication notice board 2. The transmission belt 10 is transmitted with the lower rotating wheel 616 on the inner linkage cleaning member 6 and the transmission rotating roller 8. The fourth bevel gear 68 meshes with the third bevel gear 67, and the fourth bevel gear 68 and the third bevel gear 67 have the same specification and size. The rotating cam 613 contacts the contact wheel 611, and the thickness value of the contact wheel 611 is adapted to the thickness value of the rotating cam 613. The width value of the bracket main body 61 is smaller than the diameter of the lower cleaning roller 62, and the length size of the lower cleaning roller 62 is adapted to the transmission rotating roller 8. It should be noted that a driving motor is arranged inside the transmission rotating roller 8 to drive the transmission rotating roller 8 to rotate. The driving motor is fixed on the lower support plate 3, and the driving motors on each transmission rotating roller 8 are synchronously driven by a PLC.

[0037] By fixedly installing the support column 4, the lower support plate 3 is fixed on the upper side of the support column 4. The lower support plate 3 supports the indication notice board 2. The upper side of the indication notice board 2 is clamped with the upper notice cover plate 1 to protect the internal structure. An opening window 5 is provided on the surface of the indication notice board 2 to display the current information. The transmission rotating rollers 8 inside the indication notice board 2 are arranged horizontally. The notice conveyor belt 7 is driven to roll through the transmission belt 10. The notice conveyor belt 7 surrounds the outside of the transmission rotating rollers 8 and rolls to display multiple segments of information, which is displayed through the opening window 5. The rotation of the transmission rotating roller 8 is transmitted to the lower rotating wheel 616 of the internal linkage cleaning part 6 through the transmission belt 10 to drive the linkage rod 612 to rotate. The rotation cam 613 eccentrically arranged on the linkage rod 612 drives the contact wheel 611 to move up and down, so that the bracket main body 61 moves horizontally left and right along the guide rod 618. At the same time, the third bevel gear 67 meshes with the fourth bevel gear 68 to drive the rotating shaft 66 to rotate. The rotating shaft 66 drives the lower cleaning roller 62 to rotate through the second bevel gear 64 and the first bevel gear 63. The lower cleaning roller 62 contacts the surface of the notice conveyor belt 7 and performs comprehensive cleaning through rotation and horizontal sliding. The internal pump 12 sucks the cleaning liquid from the storage tank 11 and sprays it onto the surface of the notice conveyor belt 7 through the internal spray head 13 to soften the stains and enhance the cleaning effect. The connecting spring part 614 pulls the bracket main body 61 to reset when the cam disengages, ensuring the continuous cycle of the cleaning action. At the same time, each module can be installed and disassembled independently. This significantly simplifies the assembly process and reduces the installation time. At the same time, when a certain part fails, only the relevant module needs to be replaced, reducing the maintenance cost and time and increasing the overall service life of the equipment. The flexibility enables the sign to adapt to different environments and usage scenarios, enhancing its applicability. Each module can be produced independently. The standardized production process reduces the complexity of customized production. The manufacturer can reuse the same module in different projects, reducing the production cost, improving the production efficiency, and shortening the product delivery cycle. With the development of technology, the sign may need to add new functional modules, such as an intelligent display system or a remote control function. The modular design makes these upgrades and expansions easy, only by adding the corresponding modules without modifying the entire system. This design method extends the product life cycle and reduces the environmental burden brought by discarded equipment. Since each module operates independently, even if a certain part fails, other parts can still operate normally. This increases the stability of the system operation and is also convenient for quickly locating and solving problems when they occur. The modular design produces and combines modules according to actual needs, avoiding overproduction and resource waste. In addition, when a module is damaged, only the specific part needs to be replaced, reducing the generation of overall waste, which conforms to the design concept of sustainable development.

If the support column 4 is a multi-section combination, it needs to be assembled according to the instruction manual to ensure that the connections between sections are firm. Fix the lower support plate 3 on the upper side of the support column 4, ensuring a stable connection. Use bolts or welding to fix it. Check the levelness of the lower support plate 3 with a level. If there is a deviation, adjust the position of the support column 4 or the lower support plate 3. Place the indication notice board 2 on the lower support plate 3, align the fixing holes, and use bolts to fix the indication notice board 2 on the lower support plate 3, ensuring that it is perpendicular to the support column 4. Snap the upper notice cover plate 1 onto the upper side of the indication notice board 2, ensuring a tight fit. Check whether the upper notice cover plate 1 completely covers the upper surface of the indication notice board 2 to prevent rainwater from entering the interior. Open an opening window 5 on the surface of the indication notice board 2, ensuring that the opening size is appropriate and does not affect the stability of the internal structure. After installation, check whether the edge of the opening is smooth to avoid scratching the notice conveyor belt 7. Horizontally arrange the driving rotating rollers 8 inside the indication notice board 2, ensuring that their rotating shafts are aligned with the support connecting rods 9.

Through the rotation of the transmission rotating roller (8) inside the indicating notice board (2), the notice conveyor belt (7) is driven to move for display, and at the same time, indicating marking words are provided on the surface of the indicating notice board (2). Step S2: The transmission rotating roller (8) and the lower rotating wheel (616) on the internal linkage cleaning member (6) are driven by the transmission belt (10). The rotation of the transmission rotating roller (8) drives the lower rotating wheel (616) to rotate synchronously. The rotation of the lower rotating wheel (616) drives the whole linkage rod (612) to rotate. When the linkage rod (612) rotates, it drives the rotating cam (613) to rotate and at the same time drives the third bevel gear (67) to rotate. The third bevel gear (67) and the fourth bevel gear (68) rotate, driving the rotating shaft (66) to rotate. Subsequently, the second bevel gear (64) rotates following it under the action of the rotating shaft (66). The second bevel gear (64) meshes with the first bevel gear (63), driving the lower cleaning roller (62) to rotate. The lower cleaning roller (62) contacts the surface of the notice conveyor belt (7). At the same time, when the rotating cam (613) rotates, it drives the contact wheel (611) to rotate. The bracket main body (61) and the side fixing plate (69) are slidably connected to each other. The rotation of the rotating cam (613) drives the bracket main body (61) to reciprocate horizontally relative to the side fixing plate (69), and at the same time, the bracket main body (61) is reset under the action of the connecting spring member (614).
