[0002] A bulletin board is a display item placed in a high-traffic area for posting and announcing official documents, notices, announcements, and other informative content.

[0003] Most existing electronic bulletin boards for community public services are simply electronic screens. Due to their small size, when there is a lot of information, each piece of information needs to be displayed one by one. To facilitate viewing for the public, the time spent viewing each piece of information is relatively long, which affects the viewing experience for some people. To solve the above problems, an extended mechanism for electronic bulletin boards is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide an extension mechanism for electronic bulletin boards, which solves the problem that most existing community public service electronic bulletin boards are set up as a single electronic screen. Due to the small area of ​​the electronic bulletin board, when there is a lot of information, it is necessary to display the information one by one. In order to facilitate the viewing of the public, the time required to view each piece of information is relatively long, which affects the viewing experience of some people.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an extension mechanism for an electronic information display board, comprising a storage cabinet, a display screen, a display panel, and an extension base. The display screen is fixedly installed inside the storage cabinet. A motor is fixedly connected to one side of the extension base, and a bidirectional screw is fixedly connected to the output end of the motor. Several moving blocks are installed on the periphery of the bidirectional screw. A limiting block is fixedly connected to the upper surface of each moving block, and the upper end of the limiting block is fixedly connected to the display panel. A sliding groove is formed on the upper surface of the storage cabinet, and a pulley is installed in the sliding groove. The pulley is fixedly connected to the display panel. Several fixing components are fixedly connected to both the upper and lower surfaces of the storage cabinet.

[0007] Preferably, both sides of the expansion base are provided with oil outlets and storage boxes. The storage boxes are fixedly connected to the expansion base. The upper surface of the storage box is provided with a slot and a feed inlet. A baffle is installed in the slot. A pull plate is fixedly connected to the upper surface of the baffle. A second guide plate is fixedly connected to the storage box. A plug is installed in the feed inlet. Several vertical rods are fixedly connected to the upper surface of the storage box. Springs and pull plates are installed on the periphery of the vertical rods. The pull plate is fixedly connected to the baffle. A sealing gasket is fixedly connected to one surface of the baffle. A limit plate is fixedly connected to the upper end of the vertical rods. A partition is fixedly connected to the expansion base. The upper surface of the partition is provided with an oil inlet and several second guide plates.

[0008] Preferably, the pulley and the groove are in sliding engagement.

[0009] Preferably, the bidirectional screw is slidably engaged with the extension seat, and the moving block is threadedly engaged with the bidirectional screw.

[0010] Preferably, the bottom surface of the inner wall of the storage cabinet is provided with several limiting grooves, and the limiting block slides in conjunction with the limiting grooves.

[0012] Preferably, the plug is threaded into the storage box, the pull plate is slidably engaged with the vertical rod, the baffle is slidably engaged with the slot, and the limiting block is slidably engaged with the oil inlet.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model features a display screen, several display shelves, and pulleys. A motor drives a bidirectional screw to rotate forward, while two moving blocks move in opposite directions. These moving blocks, via limit blocks, cause the two display shelves to move in opposite directions, thus pulling the display shelves out of the storage cabinet. The display shelves are used to hold paper documents, which are then secured by magnetic blocks, allowing for the display of more information. As the display shelves move, the pulleys slide within their grooves, effectively reducing friction and making the slide smoother and easier to view.

[0015] 2. This utility model incorporates a spring, a baffle, and a sealing gasket. The storage box contains lubricating oil. Pulling the pull plate upwards causes the baffle to move upwards, allowing the lubricating oil to enter the expansion seat from the oil outlet and then fall onto the first guide plate on the partition. The first guide plate is inclined to facilitate the lubricating oil falling onto the bidirectional screw. Besides reducing friction, the lubricating oil also forms a protective film on the surface of the bidirectional screw, preventing direct metal-to-metal contact. This protective film resists external impurities and corrosive substances, significantly improving the wear resistance of the bidirectional screw and extending the service life of the equipment.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] Please see Figures 1-4 As shown, this utility model is an extension mechanism for an electronic bulletin board, including a storage cabinet 1, a display screen 2, display shelves 3, and an extension base 4. The display screen 2 is fixedly installed inside the storage cabinet 1. A motor 5 is fixedly connected to one side of the extension base 4, and a bidirectional screw 8 is fixedly connected to the output end of the motor 5. Several moving blocks 9 are installed on the periphery of the bidirectional screw 8. A limit block 10 is fixedly connected to the upper surface of the moving block 9, and the upper end of the limit block 10 is fixedly connected to the display shelf 3. A sliding groove 14 is opened on the upper surface of the storage cabinet 1, and a pulley 15 is installed in the sliding groove 14. The pulley 15 is fixedly connected to the display shelf 3. Several fixing parts 7 are fixedly connected to both the upper and lower surfaces of the storage cabinet 1. By setting up the display screen 2, several display shelves 3, and pulleys 15, when the display screen 2 is fully extended... When displaying community information that needs to be disseminated, display panel 3 is stored inside storage cabinet 1, saving space. When display screen 2 cannot fully display the information, motor 5 drives bidirectional screw 8 to rotate forward, and two moving blocks 9 move backward. The moving blocks 9 drive the two display panels 3 to move backward through limit block 10, thereby pulling the display panels 3 out of storage cabinet 1. Display panels 3 are used to place some paper documents, which are fixed by magnetic blocks, thus displaying more information. When display panels 3 move, pulley 15 slides in slide groove 14, which effectively reduces the friction of the sliding of display panels 3, making the sliding of display panels 3 smoother and more convenient to view.

[0026] Both sides of the expansion base 4 are provided with oil outlets and storage boxes 6. The storage boxes 6 are fixedly connected to the expansion base 4. The upper surface of the storage box 6 has a slot and a feed inlet. A baffle 17 is installed in the slot. A pull plate 16 is fixedly connected to the upper surface of the baffle 17. A second guide plate 19 is fixedly connected inside the storage box 6. A plug 20 is installed in the feed inlet. Several vertical rods 21 are fixedly connected to the upper surface of the storage box 6. Springs 22 and pull plates 16 are installed on the periphery of the vertical rods 21. The pull plate 16 is fixedly connected to the baffle 17. A sealing gasket 18 is fixedly connected to one surface of the baffle 17. A limit plate is fixedly connected to the upper end of the vertical rods 21. A partition 12 is fixedly connected inside the expansion base 4. The upper surface of the partition 12 is provided with an oil inlet and several second guide plates 19. By setting the springs 22, baffles 17 and sealing gaskets 18, the storage box 6 stores lubricating oil. When the display panel 3 is exposed to the outside, its surface is easily contaminated with dust. After the display panel 3 is stored in the storage cabinet 1, the dust on its surface can easily fall from the oil inlet onto the bidirectional screw 8. Over time, this can cause the bidirectional screw 8 and the moving block 9 to become stuck, thus affecting the movement of the display panel 3. Therefore, before this, the pull plate 16 is pulled upwards. The pull plate 16 drives the baffle 17 to move upwards, and the lubricating oil enters the expansion seat 4 from the oil outlet and then falls onto the first guide plate 13 on the partition 12. The first guide plate 13 is inclined to facilitate the lubricating oil falling onto the bidirectional screw 8. In addition to reducing friction, the lubricating oil can also form a protective film on the surface of the bidirectional screw 8 to prevent direct contact between metals. This protective film can resist the erosion of external impurities and corrosive substances, thereby significantly improving the wear resistance of the bidirectional screw 8 and increasing the service life of the equipment.

[0027] The pulley 15 and the groove 14 are in sliding fit.

[0028] The bidirectional screw 8 is slidably engaged with the extension seat 4, and the moving block 9 is threadedly engaged with the bidirectional screw 8.

[0029] The bottom surface of the inner wall of the storage cabinet 1 is provided with several limiting grooves 11, and the limiting block 10 slides in conjunction with the limiting grooves 11.

[0030] The position of the second guide plate 19 is adapted to the position of the oil inlet, and the position of the first guide plate 13 is adapted to the position of the oil outlet.

[0031] The plug 20 is threaded into the storage box 6, the pull plate 16 is slidably engaged with the vertical rod 21, the baffle 17 is slidably engaged with the slot, and the limit block 10 is slidably engaged with the oil inlet.

[0032] Example:

[0033] like Figures 1-4As shown, the method of using the expansion mechanism of the electronic bulletin board of this utility model is as follows: When using this utility model, firstly, the device is fixed to the storage cabinet 1 by the fixing part 7 and bolts. When the display screen 2 is large enough to display the community bulletin information to be disseminated, the display column 3 is stored in the storage cabinet 1, which can save space. When the display screen 2 cannot fully display the information, the motor 5 drives the bidirectional screw 8 to rotate forward, and the two moving blocks 9 move backward. The moving blocks 9 drive the two display columns 3 to move backward through the limit block 10, thereby pulling the display columns 3 out of the storage cabinet 1. The display columns 3 are used to place some paper documents, which are fixed by magnetic blocks, thereby displaying more information. When the display columns 3 are moving, the pulley 15 slides in the slide groove 14. The pulley 15 slides in the slide groove 14, which can effectively reduce the friction of the sliding of the display columns 3, making the display columns more flexible. 3. Sliding is smoother and easier to view. When the display panel 3 is exposed to the outside, its surface is easily covered with dust. After the display panel 3 is stored in the storage cabinet 1, the dust on its surface can easily fall from the oil inlet onto the bidirectional screw 8. Over time, this can cause the cooperation between the bidirectional screw 8 and the moving block 9 to become sticky, thus affecting the movement of the display panel 3. Therefore, before this, the pull plate 16 is pulled upward. The pull plate 16 drives the baffle 17 to move upward, and the lubricating oil enters the expansion seat 4 from the oil outlet and then falls onto the first guide plate 13 on the partition 12. The first guide plate 13 is inclined to facilitate the lubricating oil falling onto the bidirectional screw 8. In addition to reducing friction, the lubricating oil can also form a protective film on the surface of the bidirectional screw 8 to prevent direct contact between metals. This protective film can resist the erosion of external impurities and corrosive substances, thereby significantly improving the wear resistance of the bidirectional screw 8 and increasing the service life of the equipment.
