Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a hinge with a large opening angle. Background Technology

[0002] A hinge is a mechanical device used to connect two objects. It allows the connected objects to rotate relative to each other about one or more axes, while restricting movement or rotation in other directions. Hinges with a large opening angle can enable the mechanical connection to rotate at a large angle, meeting the needs of objects to be fully unfolded, folded, or positioned at multiple angles. They are commonly found in furniture, medical devices, industrial equipment, and other fields that require full utilization of space.

[0003] Currently, damage to the torsion springs in hinges with large opening angles can cause abnormal noises, collisions, or jamming during opening and closing, affecting the user experience and device stability. Moreover, it is difficult to replace them individually, and often the entire hinge needs to be replaced, increasing usage costs and reducing maintenance efficiency.

[0004] Therefore, those skilled in the art have provided a hinge with a large opening angle to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a hinge with a large opening angle. It is equipped with a disassembly structure, which can quickly disassemble the hinge seat, facilitate the replacement and maintenance of the torsion spring, ensure the hinge force, improve the stability of the device, and is equipped with a telescopic structure, which can adjust the length of the connecting column to adapt to plates of different widths, realize a large opening angle, and improve the adaptability of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A hinge with a large opening angle includes a hinge base, a first rotating seat is rotatably connected inside the hinge base, two connecting posts are provided on one side of the first rotating seat, a disassembly structure is provided at one end of the connecting post, and a telescopic structure is provided inside the connecting post. The disassembly structure includes two compression grooves located inside the connecting column. A compression spring is installed inside the compression groove. One end of the compression spring is fixedly connected to the connecting column, and the other end of the compression spring is fixedly connected to a limit ring. A locking rod is fixedly connected to the inner side of the limit ring. A torsion spring is installed inside the first rotating seat. Both the first rotating seat and the torsion spring have through holes inside, and the through holes are sleeved with the locking rod. By using the above technical solution, a disassembly structure is set up, and the locking rod is pulled to disengage it from the through hole, so that the connecting column can be separated from the first rotating seat and the second rotating seat, thereby allowing the torsion spring to be quickly disassembled and replaced, reducing maintenance costs and improving maintenance efficiency.

[0007] Furthermore, the telescopic structure includes four limiting grooves, the limiting grooves are located inside the connecting column, the limiting block slides inside the limiting groove, a connecting plate is fixedly connected to one side of the limiting block, and the two connecting columns are connected through the connecting plate; By using the above technical solution, a telescopic structure is set up, and the limiting block slides in the limiting groove, allowing the connecting column to slide outside the connecting plate, thereby realizing the adjustment of the length of the connecting column to adapt to plates of different widths and improve the applicability of the device.

[0008] Furthermore, a support plate is fixedly connected inside the connecting column, a support spring is fixedly connected to one side of the support plate, and a fixing plate is fixedly connected to the end of the support spring away from the support plate. The fixing plate is fixedly connected to the connecting plate. By using the above technical solution, a support plate and a support spring are set up, which can apply an elastic force to the connecting plate, so that the connecting column can remain stable after the extension and retraction adjustment, thereby enhancing the stability and reliability of the extension and retraction structure.

[0009] Furthermore, a second rotating seat is rotatably connected to one side of one of the connecting columns, a fixed seat is provided on one side of the second rotating seat, and a mounting seat is provided at the bottom of the fixed seat; The above technical solution provides a second rotating seat that works in conjunction with the rotation of the first rotating seat and the hinge seat to provide multi-stage rotation for the hinge to open and close at large angles, thereby expanding the hinge's rotation angle. A fixed seat and a mounting seat are provided as carriers for connecting the other end plate, enabling the hinge to connect two components that need to rotate relative to each other, thus forming a complete transmission structure.

[0010] Furthermore, one end of the second rotating seat is threadedly connected to the fixed seat via a third screw, and the interior of the fixed seat is threadedly connected to the mounting seat via two second screws; By using the above technical solution, the second rotating seat and the fixed seat can be disassembled and installed, and the fixed seat and the mounting seat can be disassembled and installed, which facilitates the individual disassembly, replacement or maintenance of each component and improves installation efficiency.

[0011] Furthermore, both the hinge seat and the mounting base are internally threaded with two first screws; The above technical solution involves setting a first screw to fix the hinge seat and the mounting seat to the two plates that need to be connected, ensuring that the hinge is installed firmly and improving the safety of the device.

[0012] Furthermore, both the fixed base and the connecting column are internally connected with a fixing rod; By using the above technical solution, a fixed rod is set up to pass through the fixed seat and the connecting column, thereby enhancing the load-bearing strength of both and preventing relative displacement or deformation when opening and closing at large angles or under large forces, thus improving the stability and load-bearing capacity of the overall hinge structure.

[0013] This utility model has the following beneficial effects: 1. The present invention proposes a hinge with a large opening angle. By setting a disassembly structure, using a locking rod and a compression spring in conjunction with a through hole for locking and fixing, the connecting column can be fixed to the first rotating seat and the second rotating seat. Pulling the locking rod to disengage it from the through hole can unlock and remove the torsion spring, reducing the cost of use and maintenance difficulty, improving maintenance efficiency, and ensuring the buffering effect and hinge force stability when the hinge is opening and closing, extending the overall service life of the hinge, and improving the stability of the device.

[0014] 2. This utility model proposes a hinge with a large opening angle. By setting a telescopic structure and using limiting blocks and limiting grooves, the connecting column can slide outside the connecting plate, thereby adjusting the overall length of the two connecting columns. This allows the hinge to adapt to plates of different widths, improving the versatility and adaptability of the device. By using a support plate and support spring, the compression fixing plate ensures the structural stability of the connecting column after the hinge length is adjusted, ensuring that the designed large-angle opening and closing function can be achieved under different plate widths. This avoids installation limitations or insufficient opening angles caused by size mismatch, and broadens the applicable scenarios of the hinge. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Reference Figures 1-4 This utility model provides a specific implementation method: A hinge with a large opening angle includes a hinge base 1. A first rotating seat 3 is rotatably connected inside the hinge base 1. Two connecting posts 5 are provided on one side of the first rotating seat 3. A disassembly structure 6 is provided at one end of each connecting post 5. A telescopic structure 7 is provided inside the connecting post 5. The disassembly structure 6 includes two compression grooves 601 located inside the connecting post 5. A compression spring 602 is provided inside the compression groove 601. One end of the compression spring 602 is fixedly connected to the connecting post 5, and the other end of the compression spring 602 is fixedly connected to a limit ring 603. A locking rod 604 is fixedly connected to the inner side of the limit ring 603. A torsion spring 8 is provided inside the first rotating seat 3. Through holes 9 are provided on both sides of the first rotating seat 3 and the torsion spring 8. The through holes 9 are engaged and fixed with the locking rod 604. By using the disassembly structure 6, pulling the locking rod 604 to disengage it from the through hole 9 can separate the connecting post 5 from the first rotating seat 3 and the second rotating seat 13, thereby allowing for quick disassembly and replacement of the torsion spring 8 and reducing maintenance costs. To improve maintenance efficiency, one end of the second rotating seat 13 is threaded to the fixed seat 4 via a third screw 12. The interior of the fixed seat 4 is threaded to the mounting seat 2 via two second screws 11. The third screw 12 allows for the disassembly and installation of the second rotating seat 13 and the fixed seat 4, and the second screws 11 allow for the disassembly and installation of the fixed seat 4 and the mounting seat 2, facilitating the individual disassembly, replacement, or repair of each component and improving installation efficiency. Both the hinge seat 1 and the mounting seat 2 are threaded with two first screws 10, which are used to fix the hinge seat 1 and the mounting seat 2 to the two plates that need to be connected, ensuring that the hinge is firmly installed and improving the safety of the device. The interior of the fixed seat 4 and the connecting column 5 are both connected by a fixing rod 14, which passes through the fixed seat 4 and the connecting column 5, enhancing the load-bearing strength of both and preventing relative displacement or deformation when opening and closing at large angles or under large forces, thereby improving the stability and load-bearing capacity of the overall hinge structure.

[0019] Reference Figure 2 , Figure 5 , Figure 6 and Figure 7The telescopic structure 7 includes four limiting grooves 701, which are located inside the connecting column 5. Limiting blocks 702 slide inside the limiting grooves 701. A connecting plate 703 is fixedly connected to one side of each limiting block 702. Two connecting columns 5 are connected via the connecting plate 703. The telescopic structure 7 allows the connecting column 5 to slide outside the connecting plate 703 by sliding the limiting blocks 702 within the limiting grooves 701, thereby adjusting the length of the connecting column 5 to accommodate plates of different widths and improve the applicability of the device. A support plate 706 is fixedly connected inside the connecting column 5. A support spring 705 is fixedly connected to one side of the support plate 706. A fixing plate 704 is fixedly connected to the end of the support spring 705 away from the support plate 706. The connecting plate 703 is fixedly connected to the connecting plate 703. A support plate 706 and a support spring 705 are provided to apply an elastic force to the connecting plate 703, so that the connecting column 5 can remain stable after telescopic adjustment, thereby enhancing the stability and reliability of the telescopic structure 7. A second rotating seat 13 is rotatably connected to one side of one of the connecting columns 5. A fixed seat 4 is provided on one side of the second rotating seat 13, and a mounting seat 2 is provided at the bottom of the fixed seat 4. The second rotating seat 13, in conjunction with the rotation of the first rotating seat 3 and the hinge seat 1, provides multi-stage rotation for the large-angle opening and closing of the hinge, thereby expanding the rotation angle of the hinge. The fixed seat 4 and the mounting seat 2 are provided as carriers for connecting the other end plate, so that the hinge can connect two parts that need to rotate relative to each other, forming a complete transmission structure.

[0020] Working principle: When using this hinge with a large opening angle, depending on the width of the plate, the two connecting posts 5 are pulled to move towards each other. The limiting block 702 slides in the limiting groove 701. At this time, the support spring 705 provides elastic support to the connecting plate 703, increasing the overall length of the two connecting posts 5 to maintain the stability of the connecting posts 5. Then, the first screw 10 is used to fix the hinge seat 1 and the mounting seat 2 to the two plates to be connected respectively. In the closed state, under the action of the torsion spring 8, the two plates are tightly closed. When the plates are rotated, the first rotating seat 3 rotates relative to the hinge seat 1, and the second rotating seat 13 rotates relative to the connecting post 5, forming a multi-segment rotating structure to achieve a large opening angle. First, by adjusting the overall length of the two connecting posts 5 when the two plates are in the unfolded state, and then installing the hinge seat 1 and the mounting seat 2, the plates are closed under the action of the support spring 705 and the torsion spring 8. The lower part is tightly closed, and the connecting post 5 only serves as a connection point. When the hinge rotates, it is mainly rotated by the torsion springs 8 on both sides, which does not affect the function of the support spring 705. The adjustment of the connecting post 5 is only used during installation. The support spring 705 strengthens the tightness between the support plate 706 and the fixed plate 704. When the plates are unfolded, a pulling force is generated to passively close the two plates, which only strengthens the tightness between the two plates. At the same time, the fixing rod 14 is used for fixation to enhance the stability of the connecting post 5. The second rotating seat 13 is fixedly connected to the fixed seat 4 using the third screw 12, and the fixed seat 4 is fixedly connected to the mounting seat 2 using the second screw 11, which strengthens the overall structural stability. When the torsion spring 8 needs to be disassembled for maintenance, pull the locking rod 604 to disengage it from the through hole 9, so that the connecting post 5 can be separated from the first rotating seat 3 and the second rotating seat 13, thereby unlocking and disassembling the torsion spring 8. The operation is reversed during installation.
