Description

Technical Field

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

[0002] Table nameplates are desktop display tools used to identify attendees, convey meeting information, product information, advertisements, or other relevant content. They are widely used in various settings such as meetings, events, classrooms, and exhibitions. Traditional table nameplates often employ a V-shaped folding design, typically consisting of two thin panels supported on the tabletop by a folded bottom. The V-shaped design results in a high center of gravity and a relatively small support area, leading to insufficient stability. This is especially problematic on student desks, where limited space and frequent movement of items make the nameplates more prone to tipping over. While the folding structure of traditional V-shaped nameplates facilitates storage, their overall size is relatively large, taking up considerable tabletop space. Since students typically need to place textbooks, stationery, notebooks, and other items on their desks, the larger size of traditional V-shaped nameplates makes the tabletop feel even more cramped, negatively impacting the student's learning experience. For example, the utility model patent with authorization announcement number CN212342169U discloses an anti-reflective, anti-slip, and anti-tipping table sign, including a "∧"-shaped table sign body. Identification mark grooves are provided on both sides of the table sign body, and an anti-reflective transparent plate is provided outside the identification mark grooves. Contact plates are provided at the bottom of both sides of the table sign body, and anti-slip pads are connected to the bottom of the contact plates. In this technical solution, the contact plates increase the contact area between the bottom of the table sign and the tabletop, preventing the table sign from tipping over, and the anti-slip pads increase the friction between the table sign and the tabletop, preventing the table sign from sliding. While the aforementioned anti-reflective, anti-slip, and anti-tipping table sign 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, a large support area is usually required to maintain stability. Furthermore, in scenarios such as meetings, classrooms, or exhibitions, audiences may come from different directions, and this fixed-angle table sign cannot adapt to the needs of multiple viewing angles and cannot meet diverse usage requirements. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a table sign that achieves rotation through the cooperation of a first latch and a first locking member. An elastic member is added between the first locking member and the base. The elastic member makes the first locking member and the first latch fit together, so that the first latch cannot rotate. This makes the rotation angle of the display board not only adjustable but also lockable. The structure is simple, reliable and more practical.

[0004] This application provides a table sign, including a display panel and a base. The display panel is provided with a first connecting part, and a first latch is installed on the first connecting part. A first locking member and an elastic member are installed in the base. The first latch is rotatably connected to the first locking member so that the display panel can rotate relative to the base. The first locking member abuts against the first latch through the action of the elastic member so that the rotation of the first latch is limited.

[0005] In this technical solution, the display panel is connected to the base via a first connecting part. The first connecting part is rotatably connected to a first locking member via a first latch, allowing the display panel to rotate relative to the base, thereby adjusting the display angle. An elastic member is added inside the base to abut against the first locking member. The elastic member drives the first locking member to press against the first latch, restricting the first latch's rotation and ensuring the display panel remains stable after adjustment to the desired angle. By applying force to the display panel, the user compresses the elastic member, allowing the first latch to rotate and the display panel to adjust its angle. After the user releases the display panel, the elastic force of the elastic element is relatively large, which allows the first latch to maintain its current position, thereby achieving angle positioning. Through the cooperation of the first latch and the first locking element, as well as the limiting function of the elastic element, the display panel can be flexibly adjusted during use while maintaining good stability. The display panel can be quickly adjusted to the optimal display angle according to different usage scenarios and needs, improving the display effect. The user only needs to adjust the angle of the display panel with a simple rotation operation, while the limiting function of the elastic element automatically fixes the angle. No complicated operation steps are required, making it extremely convenient to use.

[0006] As an improvement, the first latch is provided with a first toothed end, which engages with the first locking member; and / or, the first locking member is provided with a second toothed end, which engages with the first latch.

[0007] This technical solution provides at least three specific mating structures between the first latch and the first locking member.

[0008] One method is to provide a first toothed end only on the first latch. The first toothed end refers to the end with continuously distributed tooth-like protrusions, which is mainly used to engage or cooperate with the first locking member. The cooperation structure between the first toothed end and the first locking member provides a stable fixing effect. Under the action of the elastic element, the first toothed end can better restrict the rotation of the first latch, thereby improving the positioning efficiency of the display board. Compared with the traditional friction or snap-on fixing method, the positioning of the first toothed end is more firm and can effectively prevent the display board from shifting due to vibration or collision during use. The design of the first toothed end not only improves the stability of the display board, but also further enhances the reliability and flexibility of the structure.

[0009] Secondly, a second toothed end is provided only on the first locking member. This second toothed end, which has continuously distributed toothed protrusions, is mainly used to engage or cooperate with the corresponding latch. The cooperation structure between the toothed end and the corresponding latch provides a stable fixing effect. Under the action of the elastic element, the second toothed end can better restrict the rotation of the first latch, thereby improving the positioning efficiency of the display board. Compared with the traditional friction or snap-on fixing method, the positioning of the second toothed end is more secure and can effectively prevent the display board from shifting due to vibration or collision during use. The design of the second toothed end not only improves the stability of the display board, but also further enhances the reliability and flexibility of the structure.

[0010] Thirdly, a first toothed end is provided on the first latch, and a second toothed end is provided on the first locking member. This mating structure is the most preferred in this application. The first latch engages with the second toothed end on the first locking member through the first toothed end. When the user applies force to the display panel to make it rotate, the first latch is subjected to force through the engagement of the first toothed end and the second toothed end, so that the first locking member and the compression elastic member are compressed. The first latch rotates under force. When the user releases the display panel, the elastic force of the elastic member causes the first locking member to reset, thereby making the second toothed end mesh with the first toothed end, restricting the rotation of the first latch. This allows the display panel to be stably maintained in the required position after the angle is adjusted, and the angle will not easily change due to external force. Through the meshing of the teeth, the display panel can flexibly switch between multiple preset angles, and each angle can remain stable, realizing multiple angle positioning and meeting the display needs in different scenarios.

[0011] As an improvement, the base is provided with a mounting part, in which the first locking member and the elastic member are both installed. The mounting part has a first opening, through which the first latch passes and is inserted into the mounting part to rotatably connect with the first locking member. In this technical solution, the base is provided with a dedicated mounting part to accommodate the first locking member and the elastic member, reducing the overall structural volume and making the entire structure more compact. The first opening in the mounting part for inserting the first latch allows the first latch to rotate within the mounting part, further enhancing the stability and reliability of the overall table sign structure.

[0012] As an improvement, the outer wall of the first locking member is provided with a first limiting protrusion, and the mounting part is provided with a first sliding groove along the axial direction. The first limiting protrusion and the first sliding groove are connected to limit the rotation of the first locking member within the mounting part. In this technical solution, by cooperating with the first limiting protrusion and the first sliding groove, the first locking member can not only slide back and forth along the axial direction within the mounting part, but also prevents the first locking member from rotating circumferentially within the mounting part. When the first latch is subjected to force and rotates, the first latch acts on the first locking member, causing the first locking member to slide inward along the first sliding groove. The first locking member compresses the elastic element by sliding inward, ensuring the stability of the first locking member during use, avoiding any impact on the rotation and positioning of the first latch, and improving the reliability and stability of the entire structure.

[0013] As an improvement, the first connecting part is provided with a first through hole for the first latch to pass through, and the first latch is provided with a first elastic buckle. The first elastic buckle abuts against the first connecting part to limit the first latch to be installed on the first connecting part. In this technical solution, the first connecting part is provided with a first through hole for the first latch to pass through. By providing a first elastic buckle on the first latch, the first elastic buckle can deform and return to its original shape within a certain range. When the first latch passes through the first through hole, the first elastic buckle is deformed inward by force to pass through the first through hole. After the first latch passes through the first through hole, the first elastic buckle returns to its original shape under the action of elastic force. The first elastic buckle will abut against the side wall of the first connecting part, thereby limiting the first latch to be installed on the first connecting part. This not only makes the installation of the first latch easier but also ensures the stability of the first latch installation.

[0014] As an improvement, the first latch is provided with a first limiting end, and a first step adapted to the first limiting end is provided in the first through hole, and the first limiting end is connected to the first step; the first limiting end is an irregular structure, and the connection between the first limiting end and the first step restricts the first latch from rotating within the first connecting part. In this technical solution, after the first latch passes through the first through hole, it engages with the first step via the first limiting end, thereby restricting the axial and circumferential movement of the first latch. This ensures the stable installation of the first latch on the first connecting part, reduces the use of additional fasteners, saves space, and simplifies the assembly process. Furthermore, the first step, in conjunction with the first elastic buckle, further limits the first latch, improving its installation stability. The first limiting end is designed with an irregular shape, meaning it is not a simple circle but has a special geometric shape, such as a polygon, an asymmetrical shape, or other complex shapes. This allows the first limiting end to rotate circumferentially with the first through hole, preventing the first latch from rotating within the first connecting part. This ensures that the first latch will not rotate unnecessarily due to external forces or vibrations after installation, thereby improving the overall stability of the structure.

[0015] As an improvement, the display panel is provided with a second connecting part opposite to the first connecting part. A second latch is installed on the second connecting part, and a second locking member is installed in the base. The second latch is rotatably connected to the second locking member. An elastic member is located between the first and second locking members. The second locking member abuts against the second latch through the action of the elastic member, thereby limiting the rotation of the second latch. In this technical solution, the second connecting part is rotatably connected to the second locking member through the second latch. An elastic member is added between the first and second locking members. The function of the elastic member is to drive the first and second locking members to abut against the first and second latches respectively. The first and second latches are restricted from rotation, thereby ensuring that the display panel remains stable after being adjusted to the required angle. The user applies force to the display panel, causing the first and second locking members to compress the elastic member, thereby allowing the first and second latches to have rotational space. The display panel can be rotated to adjust the angle. After the user releases the display panel... The elastic element has a large elastic force, which allows both the first and second latches to maintain their current positions, thus achieving angle positioning. Through the cooperation of the double latches and double locking parts, as well as the limiting function of the elastic element, the display board can be flexibly adjusted during use while maintaining good stability. The display board can be quickly adjusted to the optimal display angle according to different usage scenarios and needs, improving the display effect. Users only need to adjust the angle of the display board with a simple rotation operation, while the limiting function of the elastic element automatically fixes the angle, eliminating the need for complicated operation steps and making it extremely convenient to use.

[0016] As an improvement, the second latch is provided with a third toothed end, which engages with the second locking member; and / or, the second locking member is provided with a fourth toothed end, which engages with the second latch. This technical solution provides at least three specific engagement structures between the second latch and the second locking member.

[0017] One method involves setting a first toothed end and a third toothed end on the first and second latches respectively. The toothed end, which has continuously distributed tooth-like protrusions, is mainly used to engage or cooperate with the corresponding locking components. The cooperation structure between the toothed end and the locking component provides a stable fixing effect. Under the action of the elastic element, the first and third toothed ends can better restrict the rotation of the first and second latches, thereby improving the positioning efficiency of the display board. Compared with traditional friction or snap-on fixing methods, the positioning of the first and third toothed ends is more secure, effectively preventing the display board from shifting due to vibration or collision during use. The design of the first and third toothed ends not only improves the stability of the display board but also further enhances the reliability and flexibility of the structure.

[0018] Secondly, a second toothed end and a fourth toothed end are respectively provided on the first and second locking components. By providing a second toothed end and a fourth toothed end on the first and second locking components respectively, the toothed end refers to the end with continuously distributed tooth-like protrusions, which is mainly used to engage or cooperate with the corresponding latch. The cooperation structure between the toothed end and the corresponding latch provides a stable fixing effect. Under the action of the elastic element, the second toothed end and the fourth toothed end can better restrict the rotation of the first and second latches, thereby improving the positioning efficiency of the display board. Compared with the traditional friction or snap-on fixing method, the positioning of the second toothed end and the fourth toothed end is more firm, which can effectively prevent the display board from shifting due to vibration or collision during use. The design of the second toothed end and the fourth toothed end not only improves the stability of the display board, but also further enhances the reliability and flexibility of the structure.

[0019] Thirdly, a first toothed end and a third toothed end are respectively provided on the first and second latches, and a second toothed end and a fourth toothed end are respectively provided on the first and second locking members. This mating structure is the most preferred in this application. The first latch engages with the second toothed end on the first locking member through the first toothed end, and the second latch engages with the fourth toothed end on the second locking member through the third toothed end. When the user applies force to the display panel to make it rotate, the force on the first latch is applied through the engagement of the first and second toothed ends, and the force on the second latch is applied through the engagement of the third and fourth toothed ends, so that the first and second locking members are engaged in the same manner. The first and second latches rotate under pressure when the user releases the display panel. When the user releases the display panel, the elastic force of the elastic element resets the first and second latches, causing the second toothed end to engage with the first toothed end and the fourth toothed end to engage with the third toothed end. This restricts the rotation of the first and second latches, allowing the display panel to remain stably in the desired position after the angle is adjusted, without easily changing the angle due to external forces. Through the meshing of the teeth, the display panel can flexibly switch between multiple preset angles, and each angle remains stable, achieving multiple angle positioning to meet the display needs of different scenarios.

[0020] As an improvement, the second locking member is installed within the mounting section, which has a second opening opposite to the first opening. The second latch passes through the second opening and is inserted into the mounting section to rotatably connect with the second locking member. In this technical solution, a dedicated mounting section is provided on the base to accommodate the first locking member, the second locking member, and the elastic member, reducing the overall structural volume and making the entire structure more compact. The mounting section has a first opening and a second opening for inserting the first latch and the second latch, respectively. This design allows the first latch and the second latch to rotate within the mounting section, further enhancing the stability and reliability of the overall table sign structure.

[0021] As an improvement, the outer wall of the second locking member is provided with a second limiting protrusion, and the mounting part is provided with a second sliding groove along the axial direction. The second limiting protrusion and the second sliding groove are connected to limit the rotation of the second locking member within the mounting part. In this technical solution, by cooperating with the second limiting protrusion and the second sliding groove, the second locking member can not only slide back and forth along the axial direction within the mounting part, but also prevents the second locking member from rotating circumferentially within the mounting part. When the second latch is subjected to force and rotates, the second latch acts on the second locking member, causing the second locking member to slide inward along the second sliding groove. The second locking member compresses the elastic element by sliding inward, ensuring the stability of the second locking member during use, avoiding any impact on the rotation and positioning of the second latch, and improving the reliability and stability of the entire structure.

[0022] As an improvement, the second connecting part is provided with a second through hole for the second latch to pass through, and the second latch is provided with a second elastic buckle. The second elastic buckle abuts against the second connecting part to limit the installation of the second latch on the second connecting part. In this technical solution, the second connecting part is provided with a second through hole for the second latch to pass through. By providing a second elastic buckle on the second latch, the second elastic buckle can deform and return to its original shape within a certain range. When the second latch passes through the second through hole, the second elastic buckle is deformed inward under force to pass through the second through hole. After the second latch passes through the second through hole, the second elastic buckle returns to its original shape under the action of elastic force. The second elastic buckle abuts against the side wall of the second connecting part, thereby limiting the installation of the second latch on the second connecting part. This not only makes the installation of the second latch easier but also ensures the stability of the installation of the second latch.

[0023] As an improvement, the second latch is provided with a second limiting end, and a second step adapted to the second limiting end is provided in the second through hole, and the second limiting end is connected to the second step; the second limiting end is an irregular structure, and the connection between the second limiting end and the second step restricts the second latch from rotating within the second connecting part. In this technical solution, after the second latch passes through the second through hole, it engages with the second step through the second limiting end, thereby restricting the axial and circumferential movement of the second latch. This ensures the stable installation of the second latch on the second connecting part, reduces the use of additional fasteners, saves space, and simplifies the assembly process. Furthermore, the cooperation between the second step and the second elastic buckle can further limit the second latch, improving its installation stability. The second limiting ends are all irregularly shaped structures, meaning that the shape of the limiting ends is not a simple circle, but has a special geometric shape, such as a polygon, an asymmetrical shape, or other complex shapes. This allows the second limiting end and the second through hole to rotate circumferentially, preventing the second latch from rotating within the second connecting part. This ensures that the second latch will not rotate unnecessarily due to external forces or vibrations after installation, thereby improving the stability of the entire structure.

[0024] As an improvement, the mounting part has an internal hollow structure and is in a straight line shape; the mounting part and the base are integrally formed. In this technical solution, the mounting part adopts an internal hollow design. This structure provides sufficient space inside the mounting part to accommodate the first locking element, the second locking element, and the elastic element. The hollow structure not only reduces the overall weight but also provides the necessary space for the installation and movement of the components, facilitating the rotational limiting function of the first and second latches. The straight line shape of the mounting part makes the entire structure more compact and easier to arrange, simplifying the overall structure. The integral forming of the mounting part and the base, which are molded as a whole during the manufacturing process rather than assembled by welding, screws, or other connection methods, improves the integrity and stability of the structure, simplifies the assembly process, and reduces production costs and assembly time.

[0025] As an improvement, the first latch, first locking element, elastic element, second locking element, and second latch are arranged sequentially along the same straight line. In this technical solution, the first latch, first locking element, elastic element, second locking element, and second latch are arranged along the same straight line, and the movement path of the latch is consistent with the mating path of the locking element and the elastic element. This ensures the smoothness of the locking and rotation process, reduces the risk of failure caused by component misalignment or inconsistent movement, and the straight-line arrangement design makes the entire mating structure smaller and more space-efficient.

[0040] Example 1

[0041] like Figures 1 to 9 As shown, this application discloses a table sign, including a display panel 1 and a base 2. The display panel 1 is provided with a first connecting part 11, and a first latch 3 is installed on the first connecting part 11. A first locking member 5 and an elastic member 7 are installed in the base 2. The first latch 3 is rotatably connected to the first locking member 5. The display panel 1 is connected to the base 2 through the first connecting part 11, and the first connecting part 11 is rotatably connected to the first locking member 5 through the first latch 3, so that the display panel 1 can rotate relative to the base 2, thereby realizing the adjustment of the display angle.

[0042] like Figure 2 and Figure 5As shown, the first locking member 5 abuts against the first latch 3 through the action of the elastic member 7 to limit the rotation of the first latch 3. An elastic member 7 is added between the first locking member 5 and the base 2. The function of the elastic member 7 is to drive the first locking member 5 to abut against the first latch 3, restricting the rotation of the first latch 3, thereby ensuring that the display panel 1 remains stable after being adjusted to the required angle. When the user applies force to the display panel 1, the first locking member 5 is compressed by the elastic member 7, allowing the first latch 3 to have room to rotate, and the display panel 1 can rotate to adjust the angle. After the user releases the display panel 1, the elastic member 7's elasticity... With sufficient force, the first latch 3 can maintain its current position, thereby achieving angle positioning. Through the cooperation of the first latch 3 and the first locking member 5, and the limiting function of the elastic member 7, the display board 1 can be flexibly adjusted during use while maintaining good stability. The display board 1 can be quickly adjusted to the optimal display angle according to different usage scenarios and needs, improving the display effect. Users can adjust the angle of the display board 1 simply by rotating it, while the limiting function of the elastic member 7 automatically fixes the angle without complicated operation steps, making it extremely convenient to use.

[0043] Example 2

[0044] like Figures 1 to 9 As shown, this embodiment provides a table sign based on Embodiment 1, with the same structure as Embodiment 1. The first latch 3 is provided with a first toothed end 31, which engages with the first locking member 5. The first toothed end 31, which has continuously distributed toothed protrusions, is mainly used for meshing or engaging with the first locking member 5. The engagement structure between the first toothed end 31 and the first locking member 5 provides a stable fixing effect. Under the action of the elastic member 7, the first toothed end 31 can better restrict the rotation of the first latch 3, thereby improving the positioning efficiency of the display board 1. Compared with traditional friction or snap-fit ​​fixing methods, the positioning of the first toothed end 31 is more secure, effectively preventing the display board 1 from shifting due to vibration or collision during use. The design of the first toothed end 31 not only improves the stability of the display board 1 but also further enhances the reliability and flexibility of the structure.

[0045] Example 3

[0046] like Figures 1 to 9As shown, this embodiment provides a table sign based on Embodiment 1, with the same structure as Embodiment 1. The first locking member 5 is provided with a second toothed end 51, which engages with the first latch 3. The second toothed end 51, which has continuously distributed toothed protrusions, is mainly used for meshing or engaging with the first latch 3. The engagement structure of the second toothed end 51 and the first latch 3 provides a stable fixing effect. Under the action of the elastic member 7, the second toothed end 51 can better restrict the rotation of the first latch 3, thereby improving the positioning efficiency of the display board 1. Compared with traditional friction or snap-fit ​​fixing methods, the positioning of the second toothed end 51 is more secure, effectively preventing the display board 1 from shifting due to vibration or collision during use. The design of the second toothed end 51 not only improves the stability of the display board 1 but also further enhances the reliability and flexibility of the structure.

[0047] Example 4

[0048] like Figures 1 to 9 As shown, this embodiment provides a table sign based on Embodiment 1, with the same structure. A first toothed end 31 is provided on the first latch 3, and a second toothed end 51 is provided on the first locking member 5. A toothed end refers to an end with continuously distributed toothed protrusions. The first latch 3 engages with the second toothed end 51 on the first locking member 5 through the first toothed end 31. When the user applies force to the display panel 1 to make it rotate, the first latch 3 is subjected to force through the engagement of the first toothed end 31 and the second toothed end 51, causing the first locking member 5 to compress the elastic element. 7. The first latch 3 rotates under force. When the user releases the display panel 1, the elastic force of the elastic element 7 causes the first locking element 5 to reset, thereby making the second toothed end 51 mesh with the first toothed end 31, restricting the rotation of the first latch 3. This allows the display panel 1 to be stably maintained in the required position after the angle is adjusted, and it will not easily change the angle due to external force. Through the meshing of the teeth, the display panel 1 can flexibly switch between multiple preset angles, and each angle can remain stable, realizing multiple angle positioning and meeting the display needs in different scenarios.

[0049] Example 5

[0050] like Figures 1 to 9As shown, this embodiment provides a table sign based on any one of embodiments one to four, with the same structure as the referenced embodiments. The base 2 has a mounting portion 21, where the first locking member 5 and the elastic member 7 are both installed. The mounting portion 21 has a first opening 211, through which the first latch 3 passes and is inserted into the mounting portion 21 to rotatably connect with the first locking member 5. The dedicated mounting portion 21 on the base 2 accommodates the first locking member 5 and the elastic member 7, reducing the overall structural volume and making the structure more compact. The first opening 211 in the mounting portion 21 allows the first latch 3 to rotate within the mounting portion 21, further enhancing the stability and reliability of the overall table sign structure.

[0051] More specifically, such as Figure 4 and Figure 8 As shown, the outer wall of the first locking member 5 is provided with a first limiting protrusion 52, and the mounting part 21 is provided with a first sliding groove 213 along the axial direction. The first limiting protrusion 52 is connected to the first sliding groove 213 so that the rotation of the first locking member 5 is limited within the mounting part 21. Through the cooperation of the first limiting protrusion 52 and the first sliding groove 213, the first locking member 5 can not only slide back and forth along the axial direction within the mounting part 21, but also prevents the first locking member 5 from rotating circumferentially within the mounting part 21. When the first latch 3 is subjected to force and rotates, the first latch 3 acts on the first locking member 5 so that the first locking member 5 is subjected to force and slides inward along the first sliding groove 213. The first locking member 5 compresses the elastic member 7 by sliding inward, which ensures the stability of the first locking member 5 during use, avoids affecting the rotation and positioning of the first latch 3, and improves the reliability and stability of the entire structure.

[0052] More specifically, such as Figure 2 , Figure 3 and Figure 9 As shown, the first connecting part 11 is provided with a first through hole 111 for the first latch 3 to pass through. The first latch 3 is provided with a first elastic buckle 32. The first elastic buckle 32 abuts against the first connecting part 11 to limit the installation of the first latch 3 on the first connecting part 11. The first connecting part 11 is provided with a first through hole 111 for the first latch 3 to pass through. By providing a first elastic buckle 32 on the first latch 3, the first elastic buckle 32 can deform and return to its original shape within a certain range. When the first latch 3 passes through the first through hole 111, the first elastic buckle 32 is deformed inward by force to pass through the first through hole 111. After the first latch 3 passes through the first through hole 111, the first elastic buckle 32 returns to its original shape under the action of elastic force. The first elastic buckle 32 will abut against the side wall of the first connecting part 11, thereby limiting the installation of the first latch 3 on the first connecting part 11. This not only makes the installation of the first latch 3 easier but also ensures the stability of the installation of the first latch 3.

[0053] More specifically, such as Figure 2 , Figure 3 and Figure 9 As shown, the first latch 3 is provided with a first limiting end 33, and a first step 112 adapted to the first limiting end 33 is provided in the first through hole 111. The first limiting end 33 is connected to the first step 112. After the first latch 3 passes through the first through hole 111, it is engaged with the first step 112 through the first limiting end 33, thereby restricting the axial and circumferential movement of the first latch 3, ensuring the stable installation of the first latch 3 on the first connecting part 11, reducing the use of additional fasteners, saving space and simplifying the assembly process. Furthermore, the first step 112 cooperates with the first elastic buckle 32 to further limit the first latch 3 and improve the installation stability of the first latch 3.

[0054] More specifically, such as Figure 2 , Figure 3 and Figure 9 As shown, the first limiting end 33 is an irregularly shaped structure. The first limiting end 33 is connected to the first step 112 to restrict the first latch 3 from rotating within the first connecting part 11. The irregularly shaped structure of the first limiting end 33 means that the shape of the limiting end is not a simple circle, but has a special geometric shape, such as a polygon, an asymmetrical shape, or other complex shapes. This allows the first limiting end 33 and the first through hole 111 to be circumferentially rotated and limited, preventing the first latch 3 from rotating within the first connecting part 11. This ensures that the first latch 3 will not rotate unnecessarily due to external forces or vibrations after installation, thereby improving the stability of the entire structure.

[0055] Example 6

[0056] like Figures 1 to 9As shown, this embodiment provides a table sign based on Embodiment 5, with the same structure. The display panel 1 has a second connecting part 12, on which a second latch 4 is installed. A second locking member 6 is installed inside the base 2. The second latch 4 and the second locking member 6 are rotatably connected. The second connecting part 12 is rotatably connected to the second locking member 6 via the second latch 4, allowing the display panel 1 to rotate relative to the base 2, thereby adjusting the display angle. An elastic member 7 is installed between the first locking member 5 and the second locking member 6. The second locking member 6, through the action of the elastic member 7, abuts against the second latch 4 to limit its rotation. The elastic member 7 drives the first locking member 5 and the second locking member 6 to abut against the first latch 3 and the second latch 4 respectively. The first latch 3 and the second latch 4 are restricted during rotation, thus ensuring that the display panel 1 remains stable after being adjusted to the desired angle. When the user applies force to the display panel 1, the first locking member 5 and the second locking member 6 compress the elastic member 7, allowing the first latch 3 and the second latch 4 to rotate. The display panel 1 can then be rotated to adjust its angle. After the user releases the display panel 1, the elastic force of the elastic member 7 is significant, ensuring that both the first latch 3 and the second latch 4 remain in their current positions, thus achieving angle positioning. Through the cooperation of the double latches and double locking members, as well as the limiting function of the elastic member 7, the display panel 1 can be flexibly adjusted during use while maintaining good stability. The display panel 1 can be quickly adjusted to the optimal display angle according to different usage scenarios and needs, improving the display effect. The user only needs to perform a simple rotation operation to adjust the angle of the display panel 1, while the limiting function of the elastic member 7 automatically fixes the angle, eliminating the need for complicated operation steps and making it extremely convenient to use.

[0057] Example 7

[0058] like Figures 1 to 9 As shown, this embodiment provides a table sign based on Embodiment Six, with the same structure. The first latch 3 has a first toothed end 31, and the second latch 4 has a third toothed end 41. The first latch 3 engages with the first locking member 5 via the first toothed end 31, and the second latch 4 engages with the second locking member 6 via the third toothed end 41. The engagement structure between the toothed end and the locking member provides a stable fixing effect. Under the action of the elastic member 7, the first toothed end 31 and the third toothed end 41 can better restrict the rotation of the first latch 3 and the second latch 4, thereby improving the positioning efficiency of the display board 1. Compared with traditional friction or snap-on fixing methods, the positioning of the first toothed end 31 and the third toothed end 41 is more secure, effectively preventing the display board 1 from shifting due to vibration or collision during use. The design of the first toothed end 31 and the third toothed end 41 not only improves the stability of the display board 1 but also further enhances the reliability and flexibility of the structure.

[0059] Example 8

[0060] like Figures 1 to 9 As shown, this embodiment provides a table card based on Embodiment Six, with the same structure. The first locking member 5 is provided with a second toothed end 51, and the second locking member 6 is provided with a fourth toothed end 61. The first locking member 5 engages with the first latch 3 via the second toothed end 51, and the second locking member 6 engages with the second latch 4 via the fourth toothed end 61. By providing the second toothed end 51 and the fourth toothed end 61 on the first locking member 5 and the second locking member 6 respectively, the engagement structure between the toothed ends and the corresponding latches provides a stable fixing effect. Under the action of the elastic element 7, the second toothed end 51 and the fourth toothed end 61 can better restrict the rotation of the first latch 3 and the second latch 4, thereby improving the positioning efficiency of the display board 1. Compared with the traditional friction or snap-on fixing method, the positioning of the second toothed end 51 and the fourth toothed end 61 is more secure, which can effectively prevent the display board 1 from shifting due to vibration or collision during use. The design of the second toothed end 51 and the fourth toothed end 61 not only improves the stability of the display board 1, but also further enhances the reliability and flexibility of the structure.

[0061] Example 9

[0062] like Figures 1 to 9 As shown, this embodiment provides a table sign based on Embodiment Six, with the same structure. A first toothed end 31 and a third toothed end 41 are respectively provided on the first latch 3 and the second latch 4. A second toothed end 51 and a fourth toothed end 61 are respectively provided on the first locking member 5 and the second locking member 6. The first latch 3 engages with the second toothed end 51 on the first locking member 5 via the first toothed end 31, and the second latch 4 engages with the fourth toothed end 61 on the second locking member 6 via the third toothed end 41. When the user applies force to the display panel 1 to rotate it, the first latch 3 is subjected to force through the engagement of the first toothed end 31 and the second toothed end 51, and the second latch 4 is subjected to force through the engagement of the third toothed end 41 and the fourth toothed end 61. This allows the first locking member 5 and the second locking member 6 to simultaneously compress the elastic member 7, causing the first latch 3 and the second latch 4 to rotate under force. When the user releases the display panel 1, the elastic force of the elastic member 7 resets the first locking member 5 and the second locking member 6, thereby engaging the second toothed end 51 with the first toothed end 31 and the fourth toothed end 61 with the third toothed end 41, restricting the rotation of the first latch 3 and the second latch 4. This ensures that the display panel 1 can stably maintain the desired position after the angle is adjusted, and will not easily change the angle due to external force. Through the meshing of the teeth, the display panel 1 can flexibly switch between multiple preset angles, and each angle can remain stable, achieving multiple angle positioning and meeting the display needs in different scenarios.

[0063] Example 10

[0064] like Figures 1 to 9 As shown, this embodiment provides a table sign based on any one of embodiments seven to nine, with the same structure as the referenced embodiments. The second locking member 6 is installed within the mounting portion 21, which has a second opening 212. The second latch 4 passes through the second opening 212 and is inserted into the mounting portion 21 to rotatably connect with the second locking member 6. A dedicated mounting portion 21 is provided on the base 2 to accommodate the first locking member 5, the second locking member 6, and the elastic member 7, reducing the overall volume and making the structure more compact. The mounting portion 21 has a first opening 211 and a second opening 212 for inserting the first latch 3 and the second latch 4, respectively. This design allows the first latch 3 and the second latch 4 to rotate within the mounting portion 21, further enhancing the stability and reliability of the overall table sign structure.

[0065] More specifically, such as Figure 4 and Figure 8 As shown, a second sliding groove 214 is provided axially inside the mounting part 21. The second limiting protrusion 62 is connected to the second sliding groove 214 to limit the rotation of the second locking member 6 within the mounting part 21. Through the cooperation of the second limiting protrusion 62 and the second sliding groove 214, the second locking member 6 can not only slide back and forth axially within the mounting part 21, but also prevents the second locking member 6 from rotating circumferentially within the mounting part 21. When the second latch 4 is subjected to force and rotates, the second latch 4 acts on the second locking member 6 to cause the second locking member 6 to slide inward along the second sliding groove 214. The second locking member 6 compresses the elastic member 7 by sliding inward, ensuring the stability of the second locking member 6 during use, avoiding affecting the rotation and positioning of the second latch 4, and improving the reliability and stability of the entire structure.

[0066] More specifically, such as Figure 2 , Figure 3 and Figure 9 As shown, the second connecting part 12 is provided with a second through hole 121 for the second latch 4 to pass through, and the second latch 4 is provided with a second elastic buckle 42. The second elastic buckle 42 abuts against the second connecting part 12 to limit the installation of the second latch 4 on the second connecting part 12. The second connecting part 12 is provided with a second through hole 121 for the second latch 4 to pass through. By providing a second elastic buckle 42 on the second latch 4, the second elastic buckle 42 can deform and return to its original shape within a certain range. When the second latch 4 passes through the second through hole 121, the second elastic buckle 42 is deformed inward by force to pass through the second through hole 121. After the second latch 4 passes through the second through hole 121, the second elastic buckle 42 returns to its original shape under the action of elastic force. The second elastic buckle 42 will abut against the side wall of the second connecting part 12, thereby limiting the installation of the second latch 4 on the second connecting part 12. This not only makes the installation of the second latch 4 easier, but also ensures the stability of the installation of the second latch 4.

[0067] More specifically, such as Figure 2 , Figure 3 and Figure 9 As shown, the second latch 4 is provided with a second limiting end 43, and a second step 122 adapted to the second limiting end 43 is provided in the second through hole 121. The second limiting end 43 is connected to the second step 122. After the second latch 4 passes through the second through hole 121, it is engaged with the second step 122 through the second limiting end 43, thereby restricting the axial and circumferential movement of the second latch 4, ensuring the stable installation of the second latch 4 on the second connecting part 12, reducing the use of additional fasteners, saving space and simplifying the assembly process. Furthermore, the second step 122 cooperates with the second elastic buckle 42 to further limit the second latch 4, improving the installation stability of the second latch 4.

[0068] More specifically, such as Figure 2 , Figure 3 and Figure 9 As shown, the second limiting end 43 has an irregular shape. The second limiting end 43 is connected to the second step 122 to restrict the second latch 4 from rotating within the second connecting part 12. The irregular shape of the second limiting end 43 means that the shape of the limiting end is not a simple circle, but has a special geometric shape, such as a polygon, an asymmetrical shape, or other complex shapes. This allows the second limiting end 43 and the second through hole 121 to rotate circumferentially and limit each other, preventing the second latch 4 from rotating within the second connecting part 12. This ensures that the second latch 4 will not rotate unnecessarily due to external forces or vibrations after installation, thereby improving the stability of the entire structure.

[0069] More specifically, such as Figure 8 As shown, the mounting part 21 has an internal hollow structure and is in a straight line shape. The hollow design of the mounting part 21 provides sufficient space inside to accommodate the first locking member 5, the second locking member 6, and the elastic member 7. The hollow structure not only reduces the overall weight but also provides the necessary space for the installation and movement of the components, facilitating the rotational limiting function of the first latch 3 and the second latch 4. The straight line shape of the mounting part 21 makes the entire structure more compact and easier to arrange, simplifying the overall structure. The mounting part 21 and the base 2 are integrally formed during the manufacturing process, rather than being assembled by welding, screws, or other connection methods. This improves the integrity and stability of the structure, simplifies the assembly process, and reduces production costs and assembly time.

[0070] More specifically, such as Figure 2 and Figure 5As shown, the first latch 3, the first locking element 5, the elastic element 7, the second locking element 6, and the second latch 4 are arranged sequentially along the same straight line. The movement path of the latch is consistent with the cooperation path of the locking element and the elastic element 7, which ensures the smoothness of the locking and rotation process and reduces the risk of failure caused by component misalignment or inconsistent movement. The straight-line arrangement design makes the entire mating structure smaller and the space utilization rate higher.

[0072] 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.
