Description

Technical Field

[0001] This application relates to the field of office supplies technology, and more specifically to a rotating table sign. Background Technology

[0002] Table nameplates, as a common desktop display tool, are widely used in various scenarios such as conference rooms, offices, exhibition halls, and commercial venues. They are mainly used to display personal information, meeting agendas, product information, and advertisements. With the development of technology and the expansion of application scenarios, the design and manufacturing technology of table nameplates are also constantly being updated. Traditional table nameplates mostly adopt a V-shaped foldable design, usually composed of two thin plates, supported on the table by the folded part at the bottom. The V-shaped table nameplate has a high center of gravity and a relatively small support area, resulting in insufficient stability. Especially on student desks, where desktop space is limited and items are frequently moved, table nameplates are more likely to be knocked over. Although the folding structure of traditional V-shaped table nameplates is convenient for storage, their overall volume is relatively large when in use, taking up a lot of desktop space. Student desks usually need to hold textbooks, stationery, notebooks, and other items. The large size of traditional V-shaped table nameplates makes the desktop appear more crowded, affecting the student's learning experience. For example, utility model patent CN215599951U discloses a multifunctional nameplate, comprising a box body formed by several box panels. The key feature is that a membrane made of transparent material is fixed to the outer wall of the box body, and the membrane and the outer wall of the box body can form a gap for accommodating nameplates, with both ends of the gap extending through. In this technical solution, magnets are placed at the edges of the box panels at both ends, making the box easy to open when used for storage or as a nameplate while maintaining a certain degree of structural stability. While the aforementioned multifunctional nameplate improves stability to some extent, it still uses a fixed display angle and cannot be adjusted according to user needs. Because it cannot be rotated or adjusted, it usually requires a large support area to maintain stability. Furthermore, in scenarios such as meetings, classrooms, or exhibitions, audiences may come from different directions, and this fixed-angle nameplate cannot adapt to such multi-view requirements and cannot meet diverse usage needs. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a rotatable table sign, which realizes the rotation function through a structure of double pivots and double connecting parts. The rotation angle of the display board can be adjusted and locked by the engagement and disengagement of the first limiting structure and the second limiting structure. The operation is simple and labor-saving and the practicality is better.

[0004] This application provides a rotatable nameplate, including a display panel and a base. The display panel is provided with a first rotating shaft and a second rotating shaft, and the base is provided with a first connecting part and a second connecting part. The first rotating shaft is rotatably connected to the first connecting part, and the second rotating shaft is rotatably connected to the second connecting part. The end of the second rotating shaft is provided with a first limiting structure, and the second connecting part is provided with a second limiting structure. When the display panel is subjected to force and moves in a first direction, the first limiting structure engages with the second limiting structure in the first direction to limit the rotation of the display panel relative to the base. When the display panel is subjected to force and moves in a second direction, the first limiting structure disengages from the second limiting structure in the second direction to unlock the rotation of the display panel relative to the base.

[0005] In this technical solution, a first rotating shaft is rotatably connected to a first connecting part, and a second rotating shaft is rotatably connected to a second connecting part, allowing the display panel to rotate back and forth on the base to achieve the rotation function of the table sign. A first limiting structure is provided at the end of the second rotating shaft, and a second limiting structure is provided inside the second connecting part. The first and second limiting structures cooperate to control the rotation state of the display panel. When the display panel is subjected to force and moves in a first direction, the first limiting structure engages with the second limiting structure in the first direction, thereby restricting the rotation of the display panel on the base. At this time, the display angle of the display panel is locked. When the display panel is subjected to force and moves in a second direction, the first limiting structure disengages from the second limiting structure in the second direction, releasing the rotation restriction. At this time, the display panel can rotate freely. The display angle can be adjusted by rotation to meet the needs of different viewing angles. The design of the first and second limiting structures ensures that the display board remains stable when locked and will not rotate accidentally due to external forces. The display board can be rotated and locked or unlocked by sliding it along the axis. Users only need to apply force in different directions to complete the limiting or unlocking operation, without the need for complicated mechanical adjustments or tools, which greatly improves the convenience of use. On the other hand, the first and second limiting structures are hidden inside the second rotating shaft and the second connecting part, reducing external interference. This not only solves the problem of the single display angle of traditional table cards, but also makes the entire table card structure compact, without taking up too much table space, improving the user experience and adaptability to various usage scenarios.

[0006] As an improvement, an elastic element is installed between the first rotating shaft and the first connecting part. The first rotating shaft abuts against the elastic element to keep the first limiting structure and the second limiting structure engaged. When the display panel is subjected to force and moves in the second direction, the first rotating shaft compresses the elastic element in the second direction, and the first limiting structure and the second limiting structure disengage in the second direction. In this technical solution, an elastic element is added between the first rotating shaft and the first connecting part. Under normal conditions, the elastic force of the elastic element acts on the first rotating shaft, causing both the first rotating shaft and the display panel to tend to move in the first direction. This allows the first limiting structure and the second limiting structure to remain engaged without the action of other external forces. When the display panel is subjected to force and moves in the second direction, the first rotating shaft compresses the elastic element in the second direction, and the first limiting structure disengages from the second limiting structure in the second direction, allowing the display panel to rotate and unlock. The elastic element not only provides locking force but also acts as a buffer during the unlocking process, reducing mechanical impact and extending the service life of the table sign.

[0007] As an improvement, the first and second rotating shafts are coaxially arranged and extend towards each other. In this technical solution, the first and second rotating shafts are arranged coaxially and facing each other, that is, the first and second rotating shafts extend towards a common center point, which makes the first and second rotating shafts tightly integrated in space, reducing the volume of the overall structure. The two rotating shafts can achieve different motion functions on the same central axis. The coaxial arrangement ensures the motion accuracy of the first and second rotating shafts, reduces shaking or jamming caused by axis deviation, and improves rotation efficiency.

[0008] As an improvement, the first connecting part and the second connecting part are coaxially distributed, and both the first connecting part and the second connecting part are located between the first rotating shaft and the second rotating shaft. In this technical solution, the first connecting part and the second connecting part are distributed along the same central axis, which enables precise alignment and coordinated movement between the two connecting parts and the two rotating shafts. Setting the first connecting part and the second connecting part to be located between the first rotating shaft and the second rotating shaft means that the rotating shaft and the connecting part are tightly integrated in space to form a compact overall structure. The first connecting part and the second connecting part play a supporting and guiding role, ensuring that the display panel can rotate smoothly. Users only need to slide the display panel axially to lock or unlock the rotation of the display panel, which is simple and effortless to use.

[0009] As an improvement, the first connecting part is provided with a first insertion hole for the first rotating shaft to pass through, and the second connecting part is provided with a second insertion hole for the second rotating shaft to pass through. The openings of the first insertion hole and the second insertion hole face opposite directions. In this technical solution, the first insertion hole in the first connecting part is provided to accommodate the first rotating shaft, ensuring that the first rotating shaft can slide or rotate therein. The second insertion hole in the second connecting part is provided to accommodate the second rotating shaft, ensuring that the second rotating shaft can slide or rotate therein. The first and second rotating shafts are distributed facing each other, and the opening directions of the first and second insertion holes are opposite, thereby meeting the assembly and movement requirements of the first and second rotating shafts, preventing the rotating shafts from disengaging from the connecting part during the movement of the display panel along the first or second direction under force, and further improving the stability of the overall structure.

[0010] As an improvement, the first limiting structure is a protruding structure, and the second limiting structure is a groove structure adapted to the first limiting structure. In this technical solution, the first and second limiting structures are coupled using a concave-convex structure. When the protruding structure is subjected to force and engages with the groove structure in the first direction, it can restrict the rotation of the display panel relative to the base, ensuring that the display panel remains locked in a specific position. When the protruding structure is subjected to force and disengages from the groove structure in the second direction, it can release the rotation restriction of the display panel relative to the base, allowing the display panel to rotate and adjust the display angle. The combination of the protruding structure and the groove structure is simple and efficient, achieving a reliable limiting function, easy to adjust and maintain, and reducing usage costs.

[0011] As an improvement, the second limiting structure includes a first groove and a second groove, the first groove and the second groove being perpendicularly distributed, the first limiting structure engaging with the first groove to make the display panel perpendicular to the base, and the first limiting structure engaging with the second groove to make the display panel parallel to the base. In this technical solution, the second limiting structure includes at least a first groove and a second groove. The first limiting structure is a protruding structure that can engage with either the first or second groove. The design of the first and second grooves allows the display panel to switch between two different positional states. When the first limiting structure engages with the first groove, the display panel is vertical relative to the base and is fixed in a vertical position, suitable for scenarios where the display panel needs to be displayed upright. When the first limiting structure engages with the second groove, the display panel is parallel relative to the base and is fixed in a parallel position, suitable for scenarios where the display panel needs to be displayed flat. The display panel can be rotated and unlocked by sliding it axially. Rotating the display panel again allows the first limiting structure to switch between the first and second grooves. The display panel can switch between vertical and parallel states to meet the display needs of different scenarios, offering high flexibility. On the other hand, this technical solution can also include a third groove in the second limiting structure. The third groove forms an angle with both the first and second grooves, with the angle ranging from 0 to 90 degrees, thereby meeting more display angle requirements for the display panel and making it suitable for various scenarios.

[0012] As an improvement, the first connecting part is provided with a snap groove, and the second connecting part is provided with a snap protrusion. The snap protrusion connects with the snap groove to engage the first connecting part and the second connecting part. In this technical solution, the snap groove is a recessed structure designed in the first connecting part to accommodate and fix the snap protrusion of the second connecting part. The snap protrusion is a protruding structure designed in the second connecting part to cooperate with the snap groove to fix the two connecting parts. Through the cooperation of the snap protrusion and the snap groove, the first connecting part and the second connecting part can be tightly engaged to form an integral structure. Through the cooperation of the snap protrusion and the snap groove, the user can quickly fix the first connecting part and the second connecting part without complicated operations or tools.

[0013] As an improvement, the bottom surface of the base is provided with an adhesive layer, and the surface of the adhesive layer is covered with release paper. In this technical solution, the base can be directly fixed to the target surface through the adhesive layer, which is mostly a tabletop. The adhesive layer is usually made of an adhesive material and has good adhesion properties. The release paper covers the surface of the adhesive layer to protect its adhesiveness and prevent it from adhering to external objects before use. When in use, the user only needs to peel off the release paper to firmly adhere the base to the target surface, preventing the base and display board from falling off. It is convenient to use and highly practical.

[0014] As an improvement, the end of the first rotating shaft is provided with a mounting shaft adapted to the elastic element. The diameter of the mounting shaft is smaller than the diameter of the first rotating shaft, and the elastic element is fitted onto the mounting shaft. In this technical solution, the mounting shaft at the end of the first rotating shaft, with a diameter smaller than the diameter of the first rotating shaft, forms a stepped structure, providing a mounting position for the elastic element and preventing displacement or detachment of the elastic element during operation. One end of the elastic element abuts against the end of the first rotating shaft, and the other end of the elastic element abuts against the first connecting part, providing elastic support for the first rotating shaft and ensuring smooth sliding of the display panel.

[0025] like Figures 1 to 5 As shown, this application discloses a rotatable nameplate, including a display panel 1 and a base 2. The display panel 1 is provided with a first rotating shaft 11 and a second rotating shaft 12. The base 2 is provided with a first connecting part 3 and a second connecting part 4. The first rotating shaft 11 is rotatably connected to the first connecting part 3, and the second rotating shaft 12 is rotatably connected to the second connecting part 4. A first limiting structure 121 is provided at the end of the second rotating shaft 12, and a second limiting structure 41 is provided inside the second connecting part 4. By rotatably connecting the first rotating shaft 11 to the first connecting part 3 and the second rotating shaft 12 to the second connecting part 4, the display panel 1 is allowed to rotate back and forth on the base 2 to realize the rotation function of the nameplate. The first limiting structure 121 is provided at the end of the second rotating shaft 12, and the second limiting structure 41 is provided inside the second connecting part 4. The first limiting structure 121 and the second limiting structure 41 cooperate to control the rotation state of the display panel 1.

[0026] When the display panel 1 is subjected to force and moves along the first direction, the first limiting structure 121 engages with the second limiting structure 41 along the first direction, thereby restricting the rotation of the display panel 1 on the base 2. At this time, the display angle of the display panel 1 is locked. When the display panel 1 is subjected to force and moves along the second direction, the first limiting structure 121 disengages from the second limiting structure 41 along the second direction, releasing the rotation restriction. At this time, the display panel 1 can rotate to adjust the display angle to meet the needs of different viewing angles. The design of the first limiting structure 121 and the second limiting structure 41 ensures that the display panel 1 remains stable in the unlocked state and will not rotate accidentally due to external force. The rotation locking or unlocking of the display panel 1 can be achieved by sliding the display panel 1 axially. The user only needs to apply force. Forces in different directions can complete the limiting or unlocking operation without the need for complex mechanical adjustments or tool assistance, greatly improving ease of use. On the other hand, the first limiting structure 121 and the second limiting structure 41 are hidden inside the second rotating shaft 12 and the second connecting part 4, reducing external interference. This not only solves the problem of the single display angle of traditional table cards, but also makes the entire table card structure compact, without occupying too much table space, improving user experience and adaptability to usage scenarios. It should be noted that the first direction in this application refers to the direction of movement from the second connecting part 4 to the first connecting part 3, i.e., direction F1 in the figure, and the second direction refers to the direction of movement from the first connecting part 3 to the second connecting part 4, i.e., direction F2 in the figure.

[0027] More specifically, such as Figure 2 As shown, an elastic element 5 is installed between the first rotating shaft 11 and the first connecting part 3. The first rotating shaft 11 and the elastic element 5 abut against each other to keep the first limiting structure 121 and the second limiting structure 41 engaged. When the display panel 1 is subjected to force and moves in the second direction, the first rotating shaft 11 compresses the elastic element 5 in the second direction, and the first limiting structure 121 and the second limiting structure 41 disengage in the second direction. An elastic element 5 is added between the first rotating shaft 11 and the first connecting part 3. Under normal conditions, the elastic force of the elastic element 5 acts on the first rotating shaft 11, causing the first... Both the pivot 11 and the display panel 1 tend to move in the first direction, so that the first limiting structure 121 and the second limiting structure 41 remain engaged without the action of other external forces. When the display panel 1 is subjected to force and moves in the second direction, the first pivot 11 compresses the elastic element 5 in the second direction, and the first limiting structure 121 disengages from the second limiting structure 41 in the second direction, thus enabling the display panel 1 to rotate and unlock. The elastic element 5 not only provides locking force but also plays a buffering role during the unlocking process, reducing mechanical impact and extending the service life of the table card.

[0028] More specifically, such as Figure 3As shown, the first rotating shaft 11 and the second rotating shaft 12 are coaxially arranged and extend towards each other. The first rotating shaft 11 and the second rotating shaft 12 are arranged coaxially and distributed towards each other, that is, the first rotating shaft 11 and the second rotating shaft 12 extend towards a common center point, so that the first rotating shaft 11 and the second rotating shaft 12 are tightly integrated in space, reducing the volume of the overall structure. The two rotating shafts can realize different motion functions on the same central axis. The coaxial arrangement ensures the motion accuracy of the first rotating shaft 11 and the second rotating shaft 12, reduces the shaking or jamming caused by axis deviation, and has higher rotation efficiency.

[0029] More specifically, such as Figure 1 As shown, the first connecting part 3 and the second connecting part 4 are coaxially distributed. Both the first connecting part 3 and the second connecting part 4 are located between the first rotating shaft 11 and the second rotating shaft 12. The first connecting part 3 and the second connecting part 4 are distributed along the same central axis, which enables precise alignment and coordinated movement between the two connecting parts and the two rotating shafts. The fact that the first connecting part 3 and the second connecting part 4 are both located between the first rotating shaft 11 and the second rotating shaft 12 means that the rotating shaft and the connecting part are tightly integrated in space to form a compact overall structure. The first connecting part 3 and the second connecting part 4 play a supporting and guiding role, ensuring that the display panel 1 can rotate smoothly. Users only need to slide the display panel 1 along the axis to lock or unlock the rotation of the display panel 1, which is simple and effortless to use.

[0030] More specifically, such as Figure 1 , Figure 4 and Figure 5 As shown, the first connecting part 3 is provided with a first insertion hole 31 for the first rotating shaft 11 to pass through, and the second connecting part 4 is provided with a second insertion hole 42 for the second rotating shaft 12 to pass through. The openings of the first insertion hole 31 and the second insertion hole 42 face opposite directions. The first insertion hole 31 is provided in the first connecting part 3 to accommodate the first rotating shaft 11, ensuring that the first rotating shaft 11 can slide or rotate therein. The second insertion hole 42 is provided in the second connecting part 4 to accommodate the second rotating shaft 12, ensuring that the second rotating shaft 12 can slide or rotate therein. The first rotating shaft 11 and the second rotating shaft 12 are distributed facing each other, and the opening directions of the first insertion hole 31 and the second insertion hole 42 are opposite, thereby meeting the assembly and movement requirements of the first rotating shaft 11 and the second rotating shaft 12, preventing the rotating shaft from separating from the connecting part during the movement of the display panel 1 in the first or second direction under force, and further improving the stability of the overall structure.

[0031] More specifically, such as Figure 3 and Figure 4As shown, the first limiting structure 121 is a protruding structure, and the second limiting structure 41 is a groove structure adapted to the first limiting structure 121. The first limiting structure 121 and the second limiting structure 41 are fitted with a concave-convex structure. When the protruding structure is subjected to force and engages with the groove structure in the first direction, it can restrict the rotation of the display panel 1 relative to the base 2, ensuring that the display panel 1 remains locked in a specific position. When the protruding structure is subjected to force and disengages from the groove structure in the second direction, it can release the rotation restriction of the display panel 1 relative to the base 2, and the display panel 1 can rotate to adjust the display angle. The cooperation between the protruding structure and the groove structure is simple and efficient, can achieve a reliable limiting function, is easy to adjust and maintain, and reduces the cost of use.

[0032] More specifically, such as Figure 4 As shown, the second limiting structure 41 includes a first groove 411 and a second groove 412. The first groove 411 and the second groove 412 are perpendicularly distributed. The first limiting structure 121 engages with the first groove 411 to make the display panel 1 perpendicular to the base 2, and the first limiting structure 121 engages with the second groove 412 to make the display panel 1 parallel to the base 2. The second limiting structure 41 includes at least the first groove 411 and the second groove 412. The first limiting structure 121 is a protruding structure that can engage with either the first groove 411 or the second groove 412. The design of the first groove 411 and the second groove 412 allows the display panel 1 to switch between two different position states. When the first limiting structure 121 engages with the first groove 411, the display panel 1 is in a vertical state relative to the base 2, and the display panel 1 is fixed in a vertical position, suitable for displaying... In scenarios where the display panel 1 is displayed upright, when the first limiting structure 121 engages with the second groove 412, the display panel 1 is parallel to the base 2 and is fixed in a parallel position. This is suitable for scenarios where the display panel 1 needs to be displayed flat. The display panel 1 can be rotated and unlocked by sliding it axially. Rotating the display panel 1 allows the first limiting structure 121 to switch between connecting to the first groove 411 or the second groove 412. The display panel 1 can switch between vertical and parallel states to meet the display needs of different scenarios, offering high flexibility. On the other hand, this technical solution can also include a third groove in the second limiting structure 41. The third groove forms an angle with both the first groove 411 and the second groove 412, with the angle ranging from 0 to 90 degrees, thereby meeting more display angle requirements for the display panel 1 and making it suitable for various scenarios.

[0033] More specifically, such as Figure 5As shown, the first connecting part 3 is provided with a snap groove 32, and the second connecting part 4 is provided with a snap protrusion 43. The snap protrusion 43 connects with the snap groove 32 to engage the first connecting part 3 and the second connecting part 4. The snap groove 32 is a recessed structure designed in the first connecting part 3 to accommodate and fix the snap protrusion 43 of the second connecting part 4. The snap protrusion 43 is a protruding structure designed in the second connecting part 4 to cooperate with the snap groove 32 to fix the two connecting parts. Through the cooperation of the snap protrusion 43 and the snap groove 32, the first connecting part 3 and the second connecting part 4 can be tightly engaged to form an integral structure. Through the cooperation of the snap protrusion 43 and the snap groove 32, the user can quickly fix the first connecting part 3 and the second connecting part 4 without complicated operations or tools.

[0034] More specifically, the bottom surface of the base 2 is provided with an adhesive layer, and the surface of the adhesive layer is covered with release paper. The base 2 can be directly fixed to the target surface through the adhesive layer, which is mostly a tabletop. The adhesive layer is usually made of adhesive material and has good adhesion properties. The release paper covers the surface of the adhesive layer to protect the adhesiveness of the adhesive layer and prevent the adhesive layer from adhering to external objects before use. When in use, the user only needs to peel off the release paper to firmly adhere the base 2 to the target surface, preventing the base 2 and the display board 1 from falling off. It is convenient to use and highly practical.

[0035] More specifically, such as Figure 2 and Figure 3 As shown, the end of the first rotating shaft 11 is provided with a mounting shaft 13 adapted to the elastic member 5. The diameter of the mounting shaft 13 is smaller than the diameter of the first rotating shaft 11. The elastic member 5 is fitted onto the mounting shaft 13. The mounting shaft 13 at the end of the first rotating shaft 11, with a diameter smaller than the diameter of the first rotating shaft 11, forms a stepped structure, providing an installation position for the elastic member 5 and preventing the elastic member 5 from shifting or falling off during operation. One end of the elastic member 5 abuts against the end of the first rotating shaft 11, and the other end of the elastic member 5 abuts against the first connecting part 3, providing elastic support for the first rotating shaft 11, thereby ensuring the smooth sliding of the display panel 1.

[0036] This application is not limited to the above-described preferred embodiments. Anyone can derive other products in various forms under the guidance of this application. However, regardless of any changes made to their shape or structure, any technical solution that is the same as or similar to that of this application falls within the protection scope of this application.
