Description

Technical Field

[0001] This utility model relates to the field of information display equipment technology, specifically a smart community notice board. Background Technology

[0002] Smart communities are a new model that uses technologies such as the Internet of Things and big data to improve community management and residents' living experience through intelligent means. Its core lies in the efficient integration of resources, real-time information sharing and the provision of convenient services. In the construction of smart communities, information dissemination is the key. Residents need to obtain policy notices, community updates and other information in a timely manner. However, traditional paper notice boards are slow to update and have poor interactivity, while purely electronic publicity may ignore some residents. Therefore, dual-zone notice boards that combine traditional and modern approaches have emerged to meet diverse needs and reflect the intelligent characteristics of smart communities.

[0003] The dual-zone notice board consists of a paper information posting board (mainly a hinged, openable stainless steel transparent window) and an electronic smart display screen (connected to technologies such as the Internet of Things and big data). This achieves diversified and intelligent information dissemination. The paper part is used to post static content such as policy documents and event posters, suitable for all residents. The electronic part uses Internet of Things technology to display dynamic information in real time, such as community news and safety tips, and supports video playback and touch interaction functions, making it convenient for residents to inquire about services or participate in activities. This design takes into account both tradition and modernity, meets the needs of different residents, and has become an important carrier for information dissemination in smart communities, promoting the intelligent development of communities.

[0004] However, the bulletin board equipment described above still has some shortcomings. First, when paper documents in the bulletin board are replaced, they easily leave adhesive residue on the glass surface, which not only affects the appearance but is also very troublesome to clean. Moreover, over time, paper documents are prone to bulging and bending after being exposed to moisture or sunlight, which greatly reduces the display effect and may even obscure some content, affecting residents' reading experience. This reduces the efficiency of information dissemination and increases the workload of community management, making it difficult to meet the needs of smart communities for efficient, clean, and sustainable information display. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a smart community notice board to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a smart community notice board, including a notice board body, a posting window hinged to one side of the notice board body, two sets of limiting sliding grooves symmetrically opened on the inner walls of both sides of the posting window, and a fixing mechanism for pressing paper documents is installed inside the posting window;

[0007] The fixing mechanism includes a rotating rod rotatably connected to the bottom of the posting window. Both sides of the posting window are rotatably connected to bidirectional lead screws, which are driven by bevel gears meshing with both ends of the rotating rod. A threaded sleeve is threaded onto the outer wall of the bidirectional lead screw. A stop rod is movably installed inside the posting window. Both ends of the stop rod are fixedly connected to sliders, and both sets of sliders are slidably connected to the inner wall of the limiting groove. The end of each slider away from the stop rod is rotatably connected to one end of a connecting rod, while the other end of the connecting rod is rotatably connected to the threaded sleeve. A pressure plate is movably installed on the inner wall of the posting window via springs and bolts, and one outer wall of each set of stop rods always abuts against the outer wall of the pressure plate.

[0008] By adopting the above technical solution, the torsion block and rotating rod are first rotated. The rotating rod drives two sets of lead screws to rotate synchronously through bevel gears. The threads of the two sets of lead screws drive the upper and lower sets of threaded sleeves to move closer to each other. Then, the connecting rod pulls the slider and the abutment to move along the limiting slide groove. The two sets of abutment synchronously approach and move away from the pressure plate. At the same time, the spring drives the pressure plate to move back and forth. When the pressure plate moves away from the acrylic panel, the paper document is inserted between the pressure plate and the acrylic panel through the insertion port. Then, the above-mentioned fixing mechanism is driven in the opposite direction. The pressure plate is squeezed and sticks the paper document tightly to the inner wall of the acrylic panel, realizing the automatic fixing of the paper document. It can also prevent the paper document from bubbling due to moisture and eliminate the step of using glue to stick it, indirectly solving the problem of difficult-to-remove residual glue.

[0009] Furthermore, the frame on both sides and the bottom of the posting window is provided with chambers for the fixing mechanism to move, and the threaded sleeve is slidably connected to the inner wall of the movable chamber. A set of inserts is fixed on the four outer walls of the pressure plate, and the inserts are slidably connected to the inner wall of the posting window.

[0010] By adopting the above technical solution, the pressure plate can be limited by multiple sets of inserts slidingly connected to the inner wall of the sliding groove, ensuring that the pressure plate will not deviate or tilt when moving back and forth, thus improving the stability of the equipment.

[0011] Furthermore, a sliding groove is provided at the contact position between the posting window and the insert block. A bolt that slides through the insert block is threadedly connected to the inner wall of the sliding groove. A spring is sleeved on the outer wall of the bolt, and the two ends of the spring are respectively in contact with the inner wall of the sliding groove and the end of the insert block that is close to each other.

[0012] By adopting the above technical solution, firstly, multiple sets of sliding grooves and insert blocks are used to limit the pressure plate, and then springs are used to provide elastic rebound power for the pressure plate, ensuring that the pressure plate can automatically spring back when it is not squeezed.

[0013] Furthermore, one end of the rotating rod has an outer wall that penetrates the window and is fixed with a torsion block; the cross-sectional shape of the limiting slide groove is arched; the outer diameter of the connecting rod matches the inner diameter of the limiting slide groove; and a grip is fixed to the outer wall of the abutment rod on the side away from the pressure plate.

[0014] By adopting the above technical solution, the twisting block can be easily twisted by the operator's fingers. The arched limiting slide groove and the slider can be used to drive the abutment to intermittently push the pressure plate forward and thus press the paper document for fixation. The grip can be easily held by the operator when the abutment is disassembled.

[0015] Furthermore, multiple sets of light strips are equidistantly embedded in the outer wall of the pressure plate near the abutment, and an acrylic panel is embedded in the outer wall of the posting window away from the pressure plate.

[0016] By adopting the above technical solution, multiple sets of light strips can be used to provide illumination for paper advertisements at night, thereby enhancing the display effect.

[0017] Furthermore, an electronic smart display screen is hinged to the other side of the front surface of the notice board body. An insertion port is opened on the outer wall of the posting window near the electronic smart display screen, and the insertion port is connected to the inner wall of the posting window. A sealing ring is embedded in the opening of the insertion port.

[0018] By adopting the above technical solution, the socket can facilitate the installation of paper advertisements inside the posting window, and the sealing ring can provide a certain degree of sealing protection for the socket opening, reducing the possibility of rainwater entering.

[0019] In summary, the present invention has the following main advantages:

[0020] This invention utilizes a rotating rod to drive two sets of lead screws, which in turn move threaded sleeves closer together. A connecting rod then pulls a slider and abutments along a limiting groove. The two abutments simultaneously move closer to and away from the pressure plate, while a spring moves the pressure plate back and forth. When the pressure plate moves away from the acrylic panel, a paper document is inserted between the pressure plate and the acrylic panel through an insertion slot. The reverse motion then drives the aforementioned fixing mechanism, pressing the pressure plate firmly against the inner wall of the acrylic panel, thus automatically fixing the paper document. This eliminates the need for glue and indirectly solves the problem of difficult-to-remove adhesive residue. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] A smart community bulletin board, such as Figure 1 - Figure 8 As shown, it includes a notice board body 1, a posting window 12 hinged to one side of the notice board body 1, two sets of limiting slide grooves 122 symmetrically opened on the inner walls of both sides of the posting window 12, and a fixing mechanism for pressing paper documents is installed inside the posting window 12.

[0033] The fixing mechanism includes a rotating rod 2 rotatably connected to the bottom of the posting window 12. Both sides of the posting window 12 are rotatably connected to a double-acting screw 21, and the double-acting screw 21 is driven by meshing with the two ends of the rotating rod 2 through bevel gears. The outer wall of the double-acting screw 21 is threadedly connected to a threaded sleeve 22. The inside of the posting window 12 is movably installed with a stop rod 24. Both ends of the stop rod 24 are fixedly connected to sliders 25, and both sets of sliders 25 are slidably connected to the inner wall of the limiting groove 122. The end of the slider 25 away from the stop rod 24 is rotatably connected to one end of the connecting rod 23, and the other end of the connecting rod 23 is rotatably connected to the threaded sleeve 22. The inner wall of the posting window 12 is movably installed with a pressure plate 13 through springs and bolts, and one side of the outer wall of the two sets of stop rods 24 is always abutting against the outer wall of the pressure plate 13.

[0034] This invention first rotates the torsion block and the rotating rod 2. The rotating rod 2 then drives two sets of lead screws to rotate synchronously through a bevel gear. The threads of the two sets of lead screws drive the upper and lower sets of threaded sleeves 22 to move closer together. Then, the connecting rod 23 pulls the slider 25 and the abutment rod 24 to move along the limiting groove 122. The two sets of abutment rods 24 simultaneously approach and move away from the pressure plate 13. At the same time, the spring drives the pressure plate 13 to move back and forth. When the pressure plate 13 moves away from the acrylic panel, the paper document is inserted between the pressure plate 13 and the acrylic panel through the insertion slot 121. Then, the above-mentioned fixing mechanism is driven in the opposite direction. The pressure plate 13 is squeezed and presses the paper document tightly against the inner wall of the acrylic panel, realizing the automatic fixing of the paper document. It can also prevent the paper document from becoming hollow due to moisture and eliminate the step of using glue to stick it, indirectly solving the problem of difficult-to-remove residual glue.

[0035] Please see Figure 4 - Figure 8 The frame inside the posting window 12 on both sides and at the bottom is provided with chambers for the fixed mechanism to move. The threaded sleeve 22 is slidably connected to the inner wall of the movable chamber. Each of the four outer walls of the pressure plate 13 is fixed with a set of inserts 131, and the inserts 131 are slidably connected to the inner wall of the posting window 12. By setting the above structure, the pressure plate 13 can be limited by multiple sets of inserts 131 slidably connected to the inner wall of the sliding groove, so as to ensure that the pressure plate 13 will not deviate or tilt when moving back and forth, thus improving the stability of the equipment.

[0036] Please see Figure 4 - Figure 8 A sliding groove is provided at the contact position between the posting window 12 and the insert block 131. A bolt that slides through the insert block 131 is threadedly connected to the inner wall of the sliding groove. A spring is sleeved on the outer wall of the bolt, and the two ends of the spring are respectively in contact with the inner wall of the sliding groove and the end of the insert block 131 that is close to each other. By setting the above structure, this utility model first uses multiple sets of sliding grooves to cooperate with the insert block 131 to limit the pressure plate 13, and then uses the spring to provide elastic rebound power for the pressure plate 13, ensuring that the pressure plate 13 can automatically spring back when it is not squeezed.

[0037] Please see Figure 4 - Figure 8 One end of the rotating rod 2 has an outer wall that penetrates the posting window 12 and is fixed with a twisting block. The cross-sectional shape of the limiting slide groove 122 is arched. The outer diameter of the connecting rod 23 matches the inner diameter of the limiting slide groove 122. The outer wall of the abutment rod 24 away from the pressure plate 13 is fixed with a gripping rod 26. By setting the above structure, the twisting block can be easily twisted by the operator's fingers. The arched limiting slide groove 122 and the slider 25 can be used to drive the abutment rod 24 to intermittently push the pressure plate 13 forward and press the paper document for fixation. The gripping rod 26 can be easily held by the operator when disassembling the abutment rod 24.

[0038] Please see Figure 4 - Figure 8 Multiple sets of light strips are equidistantly embedded in the outer wall of the pressure plate 13 near the abutment rod 24, and an acrylic panel is embedded in the outer wall of the posting window 12 away from the pressure plate 13. By setting the above structure, this utility model can provide lighting for paper advertisements at night using multiple sets of light strips, thereby improving the display effect.

[0039] Please see Figure 1 - Figure 3 An electronic smart display screen 11 is hinged to the other side of the front surface of the notice board body 1. An insertion port 121 is provided on the outer wall of the posting window 12 near the electronic smart display screen 11, and the insertion port 121 is connected to the inner wall of the posting window 12. A sealing ring is embedded in the opening of the insertion port 121. By setting the above structure, the insertion port 121 can facilitate the insertion of paper advertisements into the posting window 12 for installation. The sealing ring can provide a certain degree of sealing protection for the opening of the insertion port 121, reducing the possibility of rainwater entering.

[0040] The working principle of this utility model is as follows: When pasting paper documents, first open the pasting window 12, then rotate the torsion block and the rotating rod 2. The rotating rod 2 drives two sets of lead screws to rotate synchronously through the bevel gear. The threads of the two sets of lead screws drive the upper and lower sets of threaded sleeves 22 to move closer to each other. Then, the connecting rod 23 pulls the slider 25 and the abutment rod 24 to move along the limiting groove 122. The two sets of abutment rods 24 synchronously approach and move away from the pressure plate 13. At the same time, the spring drives the pressure plate 13 to move back and forth. When the pressure plate 13 moves away from the acrylic panel, the paper document is inserted between the pressure plate 13 and the acrylic panel through the insertion port 121. Then, the above-mentioned fixing mechanism is driven in the opposite direction. The pressure plate 13 is squeezed and sticks the paper document tightly to the inner wall of the acrylic panel, realizing the automatic fixing of the paper document. It can also prevent the paper document from becoming hollow due to moisture, and eliminates the step of using glue to stick it, indirectly solving the problem of difficult-to-remove residual glue.
