[0017] like Figures 2 to 5As shown, in this embodiment, the present invention includes a first planar hinge base 1, a second planar hinge base 2, and a hinge transmission structure 3. The hinge transmission structure 3 includes two symmetrically arranged transmission mechanisms 4. Each transmission mechanism 4 includes a first transmission plate 5, a second transmission plate 6, a third transmission plate 7, and a fourth transmission plate 8. The first transmission plate 5 and the third transmission plate 7 are arranged crosswise and are hinged at the intersection. The upper ends of the first transmission plate 5 and the second transmission plate 6 are both hinged to the first planar hinge base 1. The lower end of the second transmission plate 6 is hinged to the upper end of the third transmission plate 7. The lower end of the first transmission plate 5 is hinged to the upper end of the fourth transmission plate 8. The lower ends of the third transmission plate 7 and the fourth transmission plate 8 are both hinged to the second planar hinge base 2. In this embodiment, the design of the first planar hinge base 1 and the second planar hinge base 2 enables easy hinge installation without the need for pre-drilling holes or creating clearances, thus reducing the difficulty of installing hinges between the panel and the cabinet. In this embodiment, the design of two symmetrically arranged transmission mechanisms 4 further stabilizes the hinge movement of this invention.

[0018] In this embodiment, the first planar hinge base 1 includes a first connecting piece 9 and two hinge pieces 10 vertically disposed on the first connecting piece 9. The two hinge pieces 10 are parallel to each other, and the two transmission mechanisms 4 are respectively hinged to the two hinge pieces 10. The first connecting piece 9 is provided with a first mounting hole 18. In this embodiment, through the design of the hinge pieces 10, the first connecting piece 9 can be designed as a planar shape, while the hinge pieces 10 can also meet the requirements of hinge connection, thus effectively achieving the goal of not needing to drill holes to avoid gaps during hinge installation.

[0019] In this embodiment, the upper ends of the first transmission plate 5 and the second transmission plate 6 in the transmission mechanism 4 are both hinged to the hinge plate 10 on the same side. By concentrating the upper ends of the first transmission plate 5 and the second transmission plate 6 on the hinge plate on the same side, this embodiment avoids the need for separate hinge structures or positions for each transmission plate, reducing additional space occupation and making the entire transmission mechanism more compact in layout. This is particularly suitable for equipment and scenarios with stringent space requirements, such as small precision instruments and portable devices. The design of the hinge plate 10 reduces the number of parts and lowers the complexity of the structure. This not only benefits product design and manufacturing but also reduces assembly errors and potential failure points caused by excessive parts, improving product reliability and stability.

[0020] In this embodiment, a first isolation post 11 and a first pin 12 passing through the first isolation post 11 are provided between the two second transmission plates 6. The upper end of the second transmission plate 6 is hinged to the hinge plate 10 through one end of the first pin 12. Both ends of the pin 12 are provided with E-type retaining rings 13. In this embodiment, the first isolation post is provided between the two first transmission plates 5, which makes full use of the space between the transmission plates, making the overall structure more compact, reducing unnecessary space occupation, and helping to realize complex mechanical transmission functions in a limited space. It is especially suitable for mechanical equipment or devices with strict space requirements. The first isolation post 11 provides a precise installation position for the first pin 12. During the assembly process, the position of the first pin 12 can be quickly and accurately determined by simply passing the first pin 12 through the first isolation post, avoiding assembly difficulties and errors caused by inaccurate positioning, and improving assembly efficiency and quality. The E-type retaining rings 13 at both ends of the first pin 12 are easy to install and remove. During assembly, simply insert the E-type snap ring 13 into the slots at both ends of the first pin to effectively prevent the first pin from coming out of the mounting hole, ensuring the stability of the hinge structure. When disassembly is required, the E-type snap ring can be easily removed using special snap ring pliers, thereby disassembling the first pin and facilitating the maintenance and repair of the transmission system.

[0021] In this embodiment, three second isolation posts 14 and second pins 15 passing through the two third transmission plates 7 are provided between them. The three second isolation posts 14 are located at the hinge points of the upper, middle, and lower ends of the third transmission plates 7, respectively. The upper end of the third transmission plate 7 and the lower end of the second transmission plate 6 are hinged together by one end of a second pin 15. The first transmission plate 5 and the third transmission plate 7 are hinged together by one end of a second second pin 15. The second planar hinge base 2 and the third transmission plate 7 are hinged together by one end of a third second pin 15. E-type retaining rings 13 are provided at both ends of the three second pins 15. In this embodiment, the three second isolation posts 14 are located at the hinge points of the upper and middle parts of the third transmission plate 7, which provides precise positioning for the third transmission plate 7. During transmission, the third transmission plate 7 needs to be precisely hinged with other components (such as the second transmission plate 6 and the first transmission plate 5). The second isolation post 14 ensures that the third transmission plate 7 is connected to other components in the correct position, preventing it from shifting during movement and thus improving the stability of the entire transmission structure. The second isolation post 14 also provides some support, distributing the force borne by the third transmission plate 7 during transmission, preventing deformation or damage due to uneven force distribution, further enhancing the stability of the structure. This design facilitates maintenance and replacement when a component malfunctions or is damaged. Because the transmission plates are hinged together by the second pin 15, and the second isolation post 14 provides positioning and support, operators can relatively easily disassemble and install the various components during maintenance. For example, if the third transmission plate 7 is damaged, it can be removed from the transmission system and replaced simply by removing the corresponding second pin 15, without causing too much impact on other components, thus reducing maintenance costs and time.

[0022] In this embodiment, two third isolation posts 16 and third pins 17 passing through the third isolation posts 16 are provided between the two fourth transmission plates 8. The two third isolation posts 16 are located at the hinge points at both ends of the fourth transmission plates 8. The upper end of the fourth transmission plate 8 and the lower end of the first transmission plate 5 are hinged through one of the third isolation posts 16, and the fourth transmission plate 8 and the second planar hinge base 2 are hinged through one end of the other third isolation post 16. E-type retaining rings 13 are provided at both ends of the two third pins 17. In this embodiment, the provision of two third isolation posts 16 between the two fourth transmission plates 8 effectively isolates the two fourth transmission plates 8, preventing them from contacting, rubbing, or interfering with each other during operation, thereby reducing wear and improving the service life of the transmission plates and the stability of the transmission. At the same time, the third isolation posts 16 also provide a certain supporting function, enhancing the rigidity and stability of the entire transmission structure, making the transmission process smoother and more reliable. Two third isolation posts 16 are located at the hinge points at both ends of the fourth transmission plate 8. This arrangement makes the hinge position of the fourth transmission plate 8 more defined and fixed. Using the third isolation posts 16 to achieve the hinge ensures the accurate axial position of the fourth transmission plate 8 during rotation, reducing transmission errors caused by hinge position deviations and improving transmission accuracy. The upper end of the fourth transmission plate 8 and the lower end of the first transmission plate 5 are hinged together by one third isolation post 16, and the fourth transmission plate 8 and the second planar hinge base 2 are hinged together by one end of the other third isolation post 16. This design makes the connection between the components more flexible, enabling complex motion transmission and conversion. Different transmission plates can rotate around their respective hinge points to complete various preset motion trajectories, meeting diverse mechanical motion requirements.

[0023] In this embodiment, the second planar hinge base 2 includes a U-shaped hinge seat 19 and two second connecting pieces 20 disposed on the same horizontal plane. The lower ends of the third transmission piece 7 and the fourth transmission piece 8 are both hinged to the opening of the U-shaped hinge seat 19. The two second connecting pieces 20 are respectively vertically disposed on the sides of both ends of the U-shaped hinge seat 19, with the opening of the U-shaped hinge seat 19 facing upwards, making the two second connecting pieces 20 vertical. Each of the two second connecting pieces 20 is provided with a second mounting hole 21. In this embodiment, the U-shaped hinge seat 19 and the two vertically disposed second connecting pieces 20 constitute a relatively stable structural frame. The U-shaped structure itself has a certain strength and rigidity, and can withstand large external forces without easily deforming. The two second connecting pieces 20 are vertically disposed on the sides of both ends of the U-shaped hinge seat 19, further enhancing the structural stability of the entire base, enabling it to maintain structural integrity and stability when subjected to complex forces, and reducing the risk of damage or deformation caused by force. Meanwhile, the second mounting holes 21 provided on the second connecting piece 20 provide clear guidance and fixing points for the installation of the entire base. During the installation process, installers can quickly and accurately fix the base in the predetermined position through these mounting holes 21, reducing the time and difficulty of the installation process.

[0024] In this embodiment, the single-unit design using pins solves the problem of product wobbling, making operation simple, practical, and reliable, greatly shortening on-site installation time and improving work efficiency. This invention enhances the performance of hinge technology; through structural optimization, easy maintenance, and a long lifespan design, it is simple to operate, practical, and reliable, significantly improving hinge functionality and usability. Therefore, it has high practical value and broad applicability.

[0025] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
