Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of furniture hardware fittings, and particularly relates to a hinge applied to furniture. BACKGROUND

[0002] Furniture hinges are indispensable key components in furniture manufacturing and are widely used in the connection and opening and closing of furniture such as cabinets, wardrobes, doors and windows. With the increasing requirements for functionality and aesthetics of furniture design, the structural design and performance optimization of hinges have become the focus of the industry. Traditional furniture hinges are usually composed of a hinge cup, a hinge arm body and an outer rocker arm, and the opening and closing of furniture door panels are achieved through a simple hinge structure. However, the traditional hinge has the following problems in actual use:

[0003] The traditional hinge often lacks an effective positioning mechanism in the closed state. During the opening or closing process of the hinge, the cooperation between the outer rocker arm and the hinge cup is not precise enough, which can easily cause shaking or noise, reducing the comfort of the furniture.

[0004] In addition, the thickness of the hinge cup is relatively thick, and if the thickness of the door panel is relatively thin, it cannot be installed on the door panel with a relatively thin thickness. SUMMARY

[0005] The utility model provides a hinge applied to furniture, the cooperation between the closing positioning part and the positioning groove part between the outer rocker arm and the hinge cup ensures the stability of the hinge in the closed state. The design of the opening and closing positioning part cooperating with the end part of the outer rocker arm makes the hinge move more smoothly during the opening and closing process, reducing shaking and noise. In addition, in the closed state of the hinge, the closing positioning part of the outer rocker arm is positioned on the positioning groove part of the hinge cup, the closing positioning part is arc-shaped and protrudes on the outer side of the outer rocker arm, and the positioning groove part of the hinge cup is designed as an open groove, which forms a clearance relative to the closing positioning part. On the one hand, it effectively reduces the thickness of the hinge cup under the condition of ensuring the normal use of the hinge, and on the other hand, it increases the mechanical strength of the outer rocker arm, so that it is not easy to deform under stress.

[0006] A hinge applied to furniture designed for this purpose, comprising a hinge cup hinged by an outer rocker arm and a hinge arm body, the outer rocker arm is provided with a closing positioning part, the closing positioning part is protrudingly arranged on the outer side of the outer rocker arm, the hinge cup is provided with an opening and closing positioning part and / or a positioning groove part; in the closed state of the hinge, the closing positioning part of the outer rocker arm is positioned on the positioning groove part of the hinge cup; the end part of the outer rocker arm is always positioned on the opening and closing positioning part during the opening and closing process of the hinge.

[0007] An arc-shaped cooperation surface is arranged between the opening and closing positioning part of the hinge cup and the end part of the outer rocker arm, and the opening and closing positioning part and the end part of the outer rocker arm form a clearance fit through the arc-shaped cooperation surface.

[0008] The hinge cup has a first opening on one side of the opening and closing positioning part to reduce the overall weight of the hinge cup.

[0009] The positioning groove is provided with a second opening to reduce the overall weight of the hinge cup.

[0010] The hinge also includes a buffer and an inner rocker arm disposed between the hinge arm and the hinge cup. A swing arm transmission assembly is provided between the buffer and the inner rocker arm and is movably connected to the hinge arm. The inner rocker arm is coupled and transmitted to the buffer through the swing arm transmission assembly. During the opening and closing of the hinge, one end of the swing arm transmission assembly acts on the buffer, and the other end of the swing arm transmission assembly acts on the inner rocker arm to achieve the buffered closing of the hinge.

[0011] The hinge arm is equipped with an adjusting member corresponding to the buffer to adjust the lever arm length of the swing arm transmission assembly, thereby adjusting the force exerted by the swing arm transmission assembly on the buffer and thus adjusting the closing speed of the hinge.

[0012] The swing arm transmission assembly includes a first swing arm and a second swing arm, which are rotatably connected to the hinge arm body respectively. The hinge arm body is provided with an adjusting component that is transmittedly connected to the second swing arm. One end of the first swing arm acts on the inner rocker arm, and one end of the second swing arm acts on the buffer.

[0013] The point of action of the other end of the first swing arm on the second swing arm is M1, and the pivot point of the second swing arm on the hinge arm is M2. The adjusting component moves and drives the second swing arm to move on the hinge arm to adjust the distance L between M1 and M2, thereby adjusting the lever arm length of the swing arm transmission assembly acting on the buffer.

[0014] The hinge arm is provided with a guide hole, and the second swing arm is provided with a connecting shaft that cooperates with the guide hole. The adjusting component drives the second swing arm to move, and the connecting shaft of the second swing arm is limited to move on the guide hole.

[0015] The hinge arm is equipped with a transmission component, which is connected to the hinge arm and the adjusting component respectively. A connecting shaft is provided between the transmission component, the hinge arm and the second swing arm. The moving component, the hinge arm and the second swing arm are connected by the connecting shaft. The connecting shaft forms the rotation fulcrum of the second swing arm on the hinge arm. The adjusting component is connected to the second swing arm through the transmission component.

[0016] An elastic element is provided between the inner rocker arm and the hinge arm. One end of the elastic element acts elastically on the inner rocker arm, and the other end of the elastic element acts elastically on the hinge arm to realize the elastic opening of the hinge.

[0017] The beneficial technical effects of this utility model are as follows:

[0018] The outer rocker arm and the hinge cup are connected by a closing positioning part and a positioning groove, ensuring the stability of the hinge in the closed state. The design of the opening and closing positioning part cooperating with the end of the outer rocker arm makes the hinge movement smoother during opening and closing, reducing shaking and noise. In addition, in the closed state, the closing positioning part of the outer rocker arm is positioned on the positioning groove of the hinge cup. The closing positioning part is arc-shaped and protrudes from the outside of the outer rocker arm, while the positioning groove of the hinge cup has an open groove design, forming a clearance space relative to the closing positioning part. On the one hand, this effectively reduces the thickness of the hinge cup under normal use conditions, and on the other hand, it increases the mechanical strength of the outer rocker arm, making it less prone to deformation under stress.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0029] See Figures 1-8 A hinge used in furniture includes a hinge cup 3 that is hinged to a hinge arm 2 via an outer rocker arm 1. The outer rocker arm 1 is provided with a closing positioning part 5, which protrudes from the outer side of the outer rocker arm 1. The hinge cup 3 is provided with an opening and closing positioning part 6 and / or a positioning groove part 4. When the hinge is closed, the closing positioning part 5 of the outer rocker arm 1 is positioned on the positioning groove part 4 of the hinge cup 3. The end of the outer rocker arm 1 is always positioned on the opening and closing positioning part 6 during the opening and closing of the hinge.

[0030] The outer rocker arm 1 and the hinge cup 3 are connected by the closing positioning part 5 and the positioning groove part 4 to ensure the stability of the hinge in the closed state. The design of the opening and closing positioning part 6 cooperating with the end of the outer rocker arm 1 makes the movement of the hinge smoother during opening and closing, reducing shaking and noise. In addition, in the closed state, the closing positioning part 5 of the outer rocker arm 1 is positioned on the positioning groove part 4 of the hinge cup 3. The closing positioning part 4 is arc-shaped and protrudes from the outside of the outer rocker arm 1, while the positioning groove part 4 of the hinge cup 3 has an open groove design, which forms a clearance space relative to the closing positioning part 4. On the one hand, this effectively reduces the thickness of the hinge cup under normal use conditions, and on the other hand, it increases the mechanical strength of the outer rocker arm 1, making it less prone to deformation under stress.

[0031] The thickness of the hinge cup 3 is reduced, making it suitable for installation on door panels 20 with smaller thicknesses.

[0032] In this embodiment, the door panel 20 is provided with a mounting groove for the embedded installation of the hinge cup 3, and the hinge cup 3 is fixed to the door panel 20 by screws.

[0033] An arc-shaped mating surface 7 is provided between the hinge cup 3 opening / closing positioning part 6 and the end of the outer rocker arm 1, forming a clearance fit between the opening / closing positioning part 6 and the end of the outer rocker arm 1 through the arc-shaped mating surface 7. This prevents excessive frictional contact between the hinge cup 3 and the outer rocker arm 1 during the hinge opening and closing process, and avoids excessive noise generated by the hinge during operation.

[0034] The hinge cup 3 has a first opening 8 on one side corresponding to the opening and closing positioning part 6 to reduce the overall weight of the hinge cup 3.

[0035] The positioning groove 4 is provided with a second opening 9 for reducing the overall weight of the hinge cup 3.

[0036] In this embodiment, the second opening 9 and the first opening 8 effectively reduce the overall weight of the hinge cup 3, effectively save production materials, and reduce production costs.

[0037] The hinge also includes a buffer 11 and an inner rocker arm 10 disposed between the hinge arm 2 and the hinge cup 3. A swing arm transmission assembly 12, which is movably connected to the hinge arm 2, is provided between the buffer 11 and the inner rocker arm 10. The inner rocker arm 10 is coupled and transmitted to the buffer 11 through the swing arm transmission assembly 12. During the opening and closing of the hinge, one end of the swing arm transmission assembly 12 acts on the buffer 11, and the other end of the swing arm transmission assembly 12 acts on the inner rocker arm 10 to achieve the buffered closing of the hinge.

[0038] In this embodiment, a connecting frame accessory 21 is provided inside the hinge arm 2, and a hinge seat is provided at one end of the buffer 11. The connecting frame accessory 21 is provided with a first shaft hole. The buffer 11 is installed inside the connecting frame accessory 21, and the first connecting shaft pin is inserted into the hinge seat of the buffer 11 along the first shaft hole of the connecting frame accessory 21 so that the outer shell of the buffer 11 is connected to the connecting frame accessory 21.

[0039] The hinge arm 2 is provided with an adjusting member 13 corresponding to the buffer 11 for adjusting the length of the lever arm of the swing arm transmission assembly 12, so as to adjust the force of the swing arm transmission assembly 12 acting on the buffer 11, thereby adjusting the closing speed of the hinge.

[0040] The swing arm transmission assembly 12 includes a first swing arm 14 and a second swing arm 15. The first swing arm 14 and the second swing arm 15 are rotatably connected to the hinge arm body 2 respectively. The hinge arm body 2 is provided with an adjusting member 13 that is pulsorily connected to the second swing arm 15. One end of the first swing arm 14 acts on the inner rocker arm 10, and one end of the second swing arm 15 acts on the buffer 11.

[0041] The point of action of the other end of the first swing arm 14 on the second swing arm 15 is M1. The pivot point of the second swing arm 15 on the hinge arm 2 is M2. The adjusting member 13 moves and drives the second swing arm 15 to move on the hinge arm 2 to adjust the distance L between M1 and M2, thereby adjusting the lever arm length of the swing arm transmission assembly 12 acting on the buffer 11.

[0042] The hinge arm 2 is provided with a guide hole 16, and the second swing arm 15 is provided with a connecting shaft 17 that cooperates with the guide hole 16. The adjusting member 13 drives the second swing arm 15 to move, and the connecting shaft 17 of the second swing arm 15 is limited to move on the guide hole 16.

[0043] The hinge arm 2 is provided with a transmission component 18, which is connected to the hinge arm 2 and the adjusting component 13 respectively. A connecting shaft 17 is provided between the transmission component 18, the hinge arm 2 and the second swing arm 15. The moving component 18, the hinge arm 2 and the second swing arm 15 are connected by the connecting shaft 17. The connecting shaft 17 forms the rotation fulcrum of the second swing arm 15 on the hinge arm 2. The adjusting component 13 is connected to the second swing arm 15 through the transmission component 18.

[0044] In this embodiment, a second shaft hole for inserting a connecting shaft 17 is provided between the transmission component 18 and the second swing arm 15.

[0045] In this embodiment, the second swing arm 15 is provided with an actuating member 22, which is hinged to the second swing arm 15. The piston rod of the buffer 11 is inserted into the groove of the actuating member 22.

[0046] In this embodiment, the adjusting member 13 is an eccentric screw, the transmission member 18 is provided with a screw hole that mates with the eccentric screw, the hinge arm 2 is provided with a strip hole, and the inner side of the head of the eccentric screw is provided with a step portion that limits the movement on the strip hole.

[0047] A second connecting pin 23 and a first hinge hole for inserting the second connecting pin 23 are provided between the first swing arm 14 and the hinge arm 2, so that the first swing arm 14 and the hinge arm 2 are movably connected. The first swing arm 14 is provided with a first rolling shaft 24 that is hinged to the first swing arm 14, and the second swing arm 15 is provided with a first bending position 25 that cooperates with the first rolling shaft 24.

[0048] A third connecting pin 26 and a second hinge hole for inserting the third connecting pin 26 are provided between the inner rocker arm 10 and the hinge arm 2, so that the inner rocker arm 10 and the hinge arm 2 are hinged.

[0049] A fourth connecting pin and a third hinge hole for inserting the fourth connecting pin are provided between the inner rocker arm 10 and the hinge cup 3, so that the inner rocker arm 10 and the hinge cup 3 are hinged.

[0050] The inner rocker arm 10 is provided with a second rolling shaft 27 that is hinged to the inner rocker arm 10, and the first swing arm 14 is provided with a second zigzag position that cooperates with the second rolling shaft 27.

[0051] An elastic element 19 is provided between the inner rocker arm 10 and the hinge arm 2. One end of the elastic element 19 acts elastically on the inner rocker arm 10, and the other end of the elastic element 19 acts elastically on the hinge arm 2 to realize the elastic opening of the hinge.

[0052] In this embodiment, a fifth connecting pin and a fourth hinge hole for inserting the fifth connecting pin are provided between the elastic member 19 and the hinge arm 2, so that the elastic member 19 and the hinge arm 2 are connected.

[0053] The inner rocker arm 10 is provided with a third rolling shaft 28, and the elastic element 19 is provided with a first foot that acts elastically on the third rolling shaft 28. The elastic element 19 is provided with second feet on both sides that act on the inner side of the hinge arm body 2, and the first foot is located between the two second feet.

[0054] The first swing arm 14 is provided with a third bend position that cooperates with the third rolling shaft 28.

[0055] When the hinge is closed, the hinge cup 3 drives the inner rocker arm 10 to move toward the first swing arm 14 and squeeze the elastic element 19. The third bend position of the first swing arm 14 and the third rolling shaft 28 of the inner rocker arm 10 first roll into contact. The inner rocker arm 10 rotates and drives the first swing arm 14 to move on the hinge arm 2. The first rolling shaft 24 of the first swing arm 14 and the first bend position 25 of the second swing arm 15 roll into contact, so that the second swing arm 15 moves on the hinge arm 2, thereby triggering the buffer 11. When the hinge is closed at a certain angle, the second rolling shaft 27 of the inner rocker arm 10 and the second bend position of the first swing arm 14 roll into contact to achieve the buffered closure of the hinge. When the hinge is opened, the spring in the buffer 11 releases its elastic force, driving the second swing arm 15 to move, thereby triggering the first swing arm 14 and the inner rocker arm 10 to move.

[0056] Using rolling contact can reduce the noise generated during the opening and closing of the hinge, and at the same time reduce the wear of the transmission contact between the two parts.

[0057] When adjusting the hinge closing speed, rotating the adjusting component 13 drives the transmission component 18 and the second swing arm 15 to move, adjusting the distance L between M1 and M2, and thus adjusting the lever arm length of the swing arm transmission component 12 acting on the buffer 11. When the distance L between M1 and M2 becomes shorter, the lever arm length of the swing arm transmission component 12 acting on the buffer 11 becomes shorter, so during the hinge closing process, the force of the swing arm transmission component 12 acting on the buffer 11 becomes smaller, and the hinge closing speed becomes slower. When the distance L between M1 and M2 increases, the force of the swing arm transmission component 12 acting on the buffer 11 becomes larger, and the hinge closing speed becomes faster.

[0058] In this embodiment, the assembly between the frame fitting 21 and the hinge arm 2 is existing technology and will not be described in detail here. The frame fitting 21 is also connected to the hinge base plate through an elastic fastening structure, and the hinge base plate is fixed on the inside of the cabinet.

[0059] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
