Description

Technical Field

[0001] This utility model relates to the field of publicity and display board technology, and specifically to a volunteer service publicity and display board. Background Technology

[0002] Promotional display boards are important tools for displaying various information, advertisements, or promotional content;

[0003] Currently, posters are usually pasted directly onto the display surface of the display board. However, for some venues, such as school playgrounds, school canteens, and community buildings, smaller promotional display boards are generally used. Since these types of promotional display boards have a smaller display surface and can hold fewer posters, they cannot meet the needs of simultaneous promotion when multiple volunteer services need to be promoted.

[0004] To address the aforementioned issues, this application proposes a volunteer service publicity and display board. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing a volunteer service publicity and display board.

The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0034] Reference Figure 1-3 A volunteer service publicity display board includes a support 1, an elliptical base plate 3 mounted on the support 1, and an adjustment structure 4 on the elliptical base plate 3. The adjustment structure 4 includes a first motor 409 and a slide rail 401 mounted on the top of the elliptical base plate 3. Two sliders 402 are slidably connected to the slide rail 401. Each slider 402 is mounted with a support plate 405, and each support plate 405 is rotatably connected with a rotating rod 406. A bidirectional threaded rod 403 is rotatably connected to the slide rail 401. A rotating block 404 is mounted on one end of the bidirectional threaded rod 403, and the outer sides of both ends of the bidirectional threaded rod 403 are threadedly connected to the inner walls of the corresponding sliders 402. A shaft 410 is mounted on the output end of the first motor 409, and the shaft 410 is detachably connected to the top end of one of the rotating rods 406. The connection involves two rotating rods 406, each with an anti-slip sleeve 407 on its outer side. A promotional poster 2 is connected between the outer sides of the two anti-slip sleeves 407. Specifically, according to the above technical solution, multiple promotional posters 2 are glued together to form a ring. Then, based on the inner diameter of the ring, rotating block 404 is rotated, causing bidirectional threaded rod 403 to rotate. The rotation of bidirectional threaded rod 403 causes two sliders 402 to move closer or further apart, thereby adjusting the distance between the two rotating rods 406. The ring is then fitted onto the two rotating rods 406. Afterward, the first motor 409 is started, causing shaft 410 to rotate. The rotation of shaft 410 drives the rotation of rotating rod 406, thus driving the transmission of multiple promotional posters 2, facilitating the simultaneous display of multiple different volunteer services.

[0035] Reference Figure 1 An elliptical base plate 3 is fitted with a transparent shell 6, and an elliptical top plate 5 is detachably fitted onto the transparent shell 6. The transparent shell 6 is used to protect the promotional poster 2 and minimize external factors, such as malicious damage or unintentional collisions, that could cause the promotional poster 2 to be damaged.

[0036] Reference Figure 2 and Figure 4 A third bolt 502 is installed on the elliptical top plate 5. The elliptical top plate 5 is connected to the transparent shell 6 through the third bolt 502, which facilitates the disassembly and assembly of the elliptical top plate 5.

[0037] An elliptical opening is provided on the elliptical top plate 5. A second bolt 501 is inserted into the elliptical top plate 5 through the elliptical opening. A mounting shell 408 is installed on the first motor 409. The elliptical top plate 5 is connected to the mounting shell 408 through the second bolt 501. The second bolt 501 facilitates the fixing of the first motor 409 to the elliptical top plate 5 and helps to support the first motor 409.

[0038] A plug 411 is installed at the bottom end of the shaft 410, and an annular block 412 is installed at the top end of one of the rotating rods 406. The plug 411 is movably inserted into the annular block 412. A first bolt 413 is installed on the annular block 412. The annular block 412 is connected to the plug 411 through the first bolt 413. The first bolt 413 facilitates the disassembly and assembly of the first motor 409.

[0039] According to the above technical solution, when it is necessary to replace the promotional poster 2, the third bolt 502, the second bolt 501 and the first bolt 413 are unscrewed in sequence, thereby disassembling the elliptical top plate 5 and the first motor 409, which facilitates the replacement of the promotional poster 2.

[0040] Reference Figure 1 and Figure 4 The transparent shell 6 is equipped with a wiping structure 7, which includes a second motor 701 installed on the top of the elliptical top plate 5 and a movable frame 703 movably sleeved on the outside of the transparent shell 6. The output end of the second motor 701 is equipped with a threaded rod 702, and the outer side of the threaded rod 702 is threadedly connected to the inner wall of the movable frame 703. A wiping ring 704 is installed at the bottom of the movable frame 703. By starting the second motor 701, it drives the threaded rod 702 to rotate. The rotation of the threaded rod 702 drives the movable frame 703 to move, thereby driving the wiping ring 704 to wipe the transparent shell 6, thus achieving the effect of ensuring that the surface of the transparent shell 6 is as clean as possible and avoiding a large amount of dirt from obstructing the view.

[0041] It should be noted that the second motor 701 is specifically a TUNYO / 6W-250W reversible small motor, which can drive the threaded rod 702 to rotate clockwise and counterclockwise. It is important to note that after starting the second motor 701, the downward position of the moving frame 703 should be observed, and the rotation direction of the second motor 701 should be adjusted in time to avoid the moving frame 703 from disengaging from the threaded rod 702.

[0042] Working principle:

[0043] This volunteer service promotion display board uses glue to form a circle with multiple promotional posters 2. Then, based on the inner diameter of the circle, rotating the rotating block 404 drives the bidirectional threaded rod 403 to rotate. The rotation of the bidirectional threaded rod 403 causes two sliders 402 to move closer or further apart, thereby adjusting the distance between the two rotating rods 406. The circle is then placed on the two rotating rods 406. After that, the first motor 409 is started, which drives the shaft 410 to rotate. The rotation of the shaft 410 drives the rotation of the rotating rods 406, thereby driving the transmission of multiple promotional posters 2, thus facilitating the simultaneous display of multiple different volunteer services.

[0044] The volunteer service publicity display board works by starting the second motor 701, which drives the threaded rod 702 to rotate. The rotation of the threaded rod 702 causes the moving frame 703 to move, which in turn causes the wiping ring 704 to wipe the transparent shell 6, thereby achieving the effect of ensuring that the surface of the transparent shell 6 is as clean as possible and avoiding a large amount of dirt from obstructing the view.
