Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically a large-angle hinge for corner cabinet doors. Background Technology

[0002] A hinge is a mechanical device used to connect two solid objects and allow relative rotation between them. It can securely connect two components, such as cabinet doors and cabinet bodies, door and window sashes and frames, so that they form a whole and allow the connected components to rotate relative to each other around an axis to achieve opening and closing actions, such as opening and closing cabinet doors. At the same time, it can bear the weight of the connected components and ensure the smoothness and stability of the rotation process. For example, the hinge of a heavy cabinet door must bear the weight of the door.

[0003] Existing corner cabinet door hinges have opening angles of 135 degrees and 165 degrees, which have a limited range of applicability. This makes it inconvenient to retrieve items in small apartments. Furthermore, the 165-degree hinge has damping, while the 135-degree hinge does not, which can easily cause abnormal noises when the door is opened and closed. Also, there is no damping effect within 15 degrees of opening, which can easily trap fingers. If the weight of both door panels is fully supported on the 165-degree hinge, it can easily cause the door to sag. Therefore, in order to solve the above problems, an improved corner cabinet door hinge with a larger angle has been proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a large-angle corner cabinet door hinge that can achieve a larger opening and closing angle than the existing 135-degree and 165-degree hinges, enabling the corner cabinet door large-angle hinge to open and close to 180 degrees, expanding its application range, and thus solving the problem of inconvenience in retrieving items in small apartments. Furthermore, due to the inclusion of a damping transmission component, the damping performance is optimized, reducing abnormal noise during opening and closing, and providing a damping effect in the 0-15 degree opening range to prevent hand pinching. At the same time, through the reasonable design of spring compression components and solid rotating fillers, the stability of the overall hinge structure is enhanced, ensuring smooth and stable hinge rotation and preventing sagging, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corner cabinet door hinge with a large angle, including a cup head, wherein a spring compression assembly is provided in the inner cavity of the cup head, and a solid rotating filler is provided at the inner end of the spring compression assembly and rotatably connected to the cup head;

[0006] A connecting tube is rotatably connected to the solid rotating filler, and a damping transmission assembly is provided in the inner cavity of the connecting tube.

[0007] The end of the connecting roll away from the solid rotating filler is rotatably connected to a connecting assembly, and the end of the connecting assembly away from the connecting roll is rotatably connected to a connecting arm.

[0008] Preferably, the spring compression assembly includes a fixed seat and a movable seat. The fixed seat is installed in the inner cavity of the cup head, and the movable seat is slidably connected to the outer port of the cup head. A spring is installed between the fixed seat and the movable seat. A slot is opened at the outer end of the movable seat, and a positioning component is engaged at the slot. Both ends of the positioning component are rotatably connected to the cup head. The solid rotating filler is located near the fixed seat.

[0009] Preferably, the damping transmission assembly includes an extended zero-angle damper and a damping transmission component, wherein the damping transmission component is installed in the inner cavity of the connecting winding, and the extended zero-angle damper is disposed in the inner cavity of the damping transmission component.

[0010] Preferably, the connecting assembly includes a connecting middle shell, a connecting large shell, and a connecting support frame. One end of the connecting middle shell is rotatably connected to one end of the connecting roll via a second positioning member. The other end of the connecting middle shell is rotatably connected to one end of the connecting arm via a second positioning member. One end of the connecting large shell is rotatably connected to the cup head via a first positioning member. The middle section of the connecting large shell is rotatably connected to the connecting middle shell via a second positioning member. The other end of the connecting large shell is rotatably connected to the top end of the connecting support frame via a second positioning member. The bottom end of the connecting support frame is rotatably connected to the middle section of the connecting arm via a second positioning member.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figures 1-6 The corner cabinet door hinge shown includes a cup head 1, a spring compression assembly 2 is provided in the inner cavity of the cup head 1, and a solid rotating filler 3 is provided at the inner end of the spring compression assembly 2, which is rotatably connected to the cup head 1.

[0023] The large-angle hinge of the corner cabinet door of this utility model provides an elastic support base through the spring compression component 2 in the cup head 1, and the solid rotating filler 3 forms a rotating connection fulcrum with the cup head 1.

[0024] A connecting roller 4 is rotatably connected to the solid rotating filler 3. A damping transmission component 5 is provided in the inner cavity of the connecting roller 4. A connecting component 6 is rotatably connected to the end of the connecting roller 4 away from the solid rotating filler 3. A connecting arm 7 is rotatably connected to the end of the connecting component 6 away from the connecting roller 4.

[0025] The connecting roller 4 receives the solid rotating filler 3 and achieves damping and buffering through the damping transmission component 5 in the inner cavity. The connecting component 6 serves as an intermediate transmission structure connecting the connecting roller 4 and the connecting arm 7. All components rotate in coordination to form a multi-node linkage transmission chain, thereby realizing the large-angle opening and closing action of the cabinet door.

[0026] Therefore, the overall structural design of the corner cabinet door large-angle hinge of this utility model provides a foundation for the cabinet door to open at a large angle. Combined with subsequent components, it can achieve a 180-degree fully open state, which broadens the application scenarios, improves the aesthetics of the door gap, and can replace the linkage 165-degree and 135-degree hinges, thus enhancing the versatility of the product.

[0027] The spring compression assembly 2 includes a fixed seat 21 and a movable seat 22. The fixed seat 21 is installed in the inner cavity of the cup head 1, and the movable seat 22 is slidably connected to the outer port of the cup head 1. A spring member 23 is installed between the fixed seat 21 and the movable seat 22. A slot 24 is opened at the outer end of the movable seat 22. A positioning member 25 is engaged at the position of the slot 24, and the two ends of the positioning member 25 are rotatably connected to the cup head 1. A solid rotating filler 3 is set near the fixed seat 21.

[0028] In the spring compression assembly 2, the fixed seat 21 is fixed in the inner cavity of the cup head 1, and the movable seat 22 slides at the outer port of the cup head 1. The spring member 23 between the fixed seat 21 and the movable seat 22 is telescopic. The compression and reset of the spring member 23 are achieved by the sliding of the movable seat 22. The positioning member 25 is snapped into the slot 24 of the movable seat 22 and rotatedly connected to the cup head 1. Together with the solid rotating filler 3, it provides elastic buffer and stable rotation fulcrum for the hinge rotation, ensuring the elastic support and smooth reset of the hinge during the opening and closing process.

[0029] The elasticity of the spring 23 provides a gentle elastic feedback when the cabinet door opens and closes, reducing hard impacts. The cooperation between the positioning component 25, the moving seat 22, and the cup head 1 enhances the stability of the rotation process, ensuring that the hinge is not easily loosened during repeated opening and closing, extending its service life, and providing a reliable elastic support foundation for the smooth rotation of the cabinet door.

[0030] The damping transmission assembly 5 includes an extended zero-angle damper 51 and a damping transmission component 52. The damping transmission component 52 is installed in the inner cavity of the connecting winding 4, and the extended zero-angle damper 51 is disposed in the inner cavity of the damping transmission component 52.

[0031] In the damping transmission assembly 5, the damping transmission component 52 is installed in the inner cavity of the connecting roller 4, and the extended zero-angle damper 51 is set in the inner cavity of the damping transmission component 52. When the hinge rotates, the connecting middle shell 61 rotates and compresses the damping transmission component 52, thereby driving the extended zero-angle damper 51 to work and generate damping force, which buffers the impact force during the rotation process.

[0032] The damping force effectively reduces the collision noise when the hinge rotates, making the opening and closing action smooth and quiet; and the extended zero-angle damper 51 ensures that the cabinet door has a damping effect when closed and when opened between 0 and 45 degrees, avoiding the phenomenon of pinching hands caused by rapid rotation within this angle range, thus improving the safety of use.

[0033] The connecting assembly 6 includes a connecting middle shell 61, a connecting large shell 62, and a connecting support frame 63. One end of the connecting middle shell 61 is rotatably connected to one end of the connecting roll 4 via a second positioning member 64. The other end of the connecting middle shell 61 is rotatably connected to one end of the connecting arm 7 via a second positioning member 64. One end of the connecting large shell 62 is rotatably connected to the cup head 1 via a first positioning member 25. The middle section of the connecting large shell 62 is rotatably connected to the connecting middle shell 61 via a second positioning member 64. The other end of the connecting large shell 62 is rotatably connected to the top of the connecting support frame 63 via a second positioning member 64. The bottom end of the connecting support frame 63 is rotatably connected to the middle section of the connecting arm 7 via a second positioning member 64.

[0034] In the connecting component 6, the connecting middle shell 61, the connecting large shell 62, and the connecting support frame 63 form a multi-node rotational connection through the positioning component 2 64. The connecting middle shell 61 is connected to the connecting roller 4 and the connecting arm 7 respectively. One end of the connecting large shell 62 is connected to the cup head 1, the middle is connected to the connecting middle shell 61, and the other end is connected to the connecting support frame 63. The bottom end of the connecting support frame 63 is connected to the connecting arm 7. The multiple components work together to form a stable support and transmission structure. By lengthening the support distance between the connecting large shell 62 and the connecting middle shell 61, and by the rotational coordination of each component, stable support and large-angle rotation guidance for the cabinet door are achieved.

[0035] The thickened connecting shell 62, connecting middle shell 61 and solid rotating filler 3, and the addition of support sleeves at the rotating connection between the connecting shell 62 and the connecting support frame 63, greatly improve the overall structural strength of the hinge, ensuring that the cabinet door will not fall when opened 180 degrees, guaranteeing stability in the large-angle opening state. The coordinated support of multiple components also further strengthens the load-bearing capacity of the hinge and extends the service life of the product.

[0036] In practical use, when it is necessary to open the cabinet door, the force of pushing the cabinet door will drive the hinge components to work together. The spring compression component 2 inside the cup head 1 responds first, and the moving seat 22 slides at the outer port of the cup head 1, so that the spring component 23 between the fixed seat 21 and the moving seat 22 is compressed. At the same time, the positioning component 25 rotates in the slot 24 of the moving seat 22, providing initial elastic support and buffer for the rotation of the cabinet door. The solid rotating filling component 3 forms a stable rotation fulcrum with the cup head 1, ensuring a smooth start to the rotation.

[0037] As the cabinet door gradually opens, the solid rotating filler 3 drives the connecting roller 4 to rotate. The damping transmission component 5 inside the connecting roller 4 begins to function. When the connecting middle shell 61 rotates, it compresses the damping transmission component 52, which in turn causes the extended zero-angle damper 51 to generate damping force. This damping force is present throughout the process of the cabinet door opening from 0 degrees to 45 degrees, avoiding the possibility of the cabinet door being pinched by a hand due to rapid rotation. At the same time, it reduces the collision noise during rotation, making the opening action smooth and quiet.

[0038] As the cabinet door continues to open to a greater angle, the connecting middle shell 61, connecting large shell 62, and connecting support frame 63 in the connecting assembly 6 begin to work together efficiently through the multi-node rotation structure formed by the positioning element 2 64. The connecting middle shell 61 connects the connecting roll 4 and the connecting arm 7. One end of the connecting large shell 62 is connected to the cup head 1, the middle is connected to the connecting middle shell 61, and the other end is connected to the connecting support frame 63. The bottom end of the connecting support frame 63 cooperates with the connecting arm 7. The extended support distance between the connecting large shell 62 and the connecting middle shell 61 provides ample space and stable guidance for the large-angle rotation of the cabinet door.

[0039] Ultimately, the cabinet door can be smoothly opened to a fully open 180 degrees. At this point, the thickened connecting shell 62, the connecting middle shell 61, the solid rotating filler 3, and the added support sleeve at the rotating part between the connecting shell 62 and the connecting support frame 63 all work together to significantly improve the overall structural strength of the hinge, ensuring that the cabinet door will not sag when opened to 180 degrees and remains stable. Moreover, this large opening angle results in a better appearance of the door gap, is suitable for a wide range of scenarios, and can replace the linkage 165-degree and 135-degree hinges, enhancing its versatility.

[0040] When the cabinet door is closed, the spring 23 in the spring compression assembly 2 returns to its original position, causing the moving seat 22 to slide, providing elastic assistance for the cabinet door to close. At the same time, the damping transmission assembly 5 continues to play a damping role during the closing process, making the closing action equally smooth and stable, avoiding hard impacts. The entire opening and closing process is safe, smooth and quiet.
