Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a hinge structure and a cabinet component. Background Art

[0002] In the related art, a cabinet assembly includes a cabinet body and a door body, and the door body is rotatably connected to the cabinet body through a hinge assembly. The cabinet assembly can be a refrigerator, a freezer, a microwave oven, a display cabinet, and other devices in which the door body is rotatably connected to the cabinet body.

[0003] In the context of embedded refrigerator industry, the demand for height adjustment of double-axis hinged doors is gradually increasing. However, the adjustable hinge in the double-axis adjustable hinge is prone to jamming and scratching when it moves relative to the door body, causing the stress state of the hinge to be abnormal and affecting the self-closing function of the door body. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the related art. To this end, the utility model proposes a hinge structure that can reduce the friction between the hinge and the self-locking groove, improve the smoothness of the door movement, and ensure the accurate realization of the door self-closing function.

[0005] The embodiment of the utility model also provides a cabinet assembly.

[0006] The first embodiment of the present invention provides a hinge structure, comprising:

[0007] The hinge seat is provided with a first connecting hole;

[0008] A plurality of articulated shafts are provided, wherein the articulated shafts are passed through the first connecting hole and are used to match the self-locking groove. At least one of the articulated shafts can be raised and lowered relative to the first connecting hole. A flange portion is provided on the articulated shaft, a boss is provided on the side of the flange portion facing the self-locking groove, and an arc contact surface is provided on the outer edge of the boss on the side facing the self-locking groove.

[0009] According to the hinge structure provided by the embodiment of the first aspect of the utility model, at least one hinge shaft in the hinge structure can be adjusted up and down relative to the first connection hole. This design allows the height of the hinge to be fine-tuned as needed in practical applications to adapt to different installation environments and connection requirements, or to compensate for the installation deviation of the door body caused by production errors, ensuring that the height of the two door bodies is consistent. This flexibility greatly enhances the versatility and adaptability of the hinge structure. The adaptation design of the hinge shaft and the self-locking groove enables the hinge structure to be automatically locked at a specific position to prevent accidental loosening or sliding. This self-locking function not only improves the stability and safety of the hinge structure, but also reduces the cumbersome operation caused by frequent adjustments. The boss provided on the hinge shaft and the arc contact surface of its outer edge optimize the contact mode between the hinge structure and the self-locking groove. The arc contact surface can provide a more uniform and stable contact force, reduce wear and noise, and at the same time enhance the reliability of the connection and avoid the scratching phenomenon of the self-locking groove and the hinge seat. In addition, the design of the boss can also increase the strength of the hinge structure to a certain extent and improve its bearing capacity.

[0010] Optionally, the outer edge of the flange portion is provided with an arc transition surface, and during the rotation of the door body, the arc transition surface is used to prevent the outer edge of the flange portion from interfering with the self-locking groove.

[0016] Optionally, the fastener comprises:

[0017] A main body, wherein the main body is inserted into the second connecting hole;

[0018] The abutting portion is suitable for abutting against the hinge shaft.

[0019] The second aspect of the utility model provides a cabinet assembly, including a cabinet body and a door body rotatably connected to the cabinet body, wherein one of the cabinet body and the door body is connected with a hinge structure as described above, and the other of the cabinet body and the door body is provided with the self-locking groove.

[0020] According to the cabinet assembly provided by the second embodiment of the utility model, by providing the above-mentioned hinge structure, the opening and closing process of the door body is smoother, thereby improving the user experience. At the same time, the height of the door body can be fine-tuned during the installation and use of the cabinet body and the door body to ensure that the heights of the two door bodies are consistent, thereby ensuring the sealing performance between the door body and the cabinet body and ensuring the realization of the self-closing function of the door body.

[0021] Optionally, the door body is adapted to switch between an open position and a closed position relative to the cabinet body;

[0022] The self-locking groove includes a self-locking section and a sliding section which are interconnected. In the open position and the closed position, the hinge shaft is in the self-locking section. During the switching process between the open position and the closed position, the hinge shaft is in the sliding section. The thickness of the groove side wall of the sliding section is greater than the thickness of the groove side wall of the self-locking section.

[0023] According to the hinge structure provided by the embodiment of the first aspect of the utility model, at least one hinge shaft in the hinge structure can be adjusted up and down relative to the first connection hole. This design allows the height of the hinge to be fine-tuned as needed in practical applications to adapt to different installation environments and connection requirements, or to compensate for the installation deviation of the door body caused by production errors, ensuring that the height of the two door bodies is consistent. This flexibility greatly enhances the versatility and adaptability of the hinge structure. The adaptation design of the hinge shaft and the self-locking groove enables the hinge structure to be automatically locked at a specific position to prevent accidental loosening or sliding. This self-locking function not only improves the stability and safety of the hinge structure, but also reduces the cumbersome operation caused by frequent adjustments. The boss provided on the hinge shaft and the arc contact surface of its outer edge optimize the contact mode between the hinge structure and the self-locking groove. The arc contact surface can provide a more uniform and stable contact force, reduce wear and noise, and at the same time enhance the reliability of the connection and avoid the scratching phenomenon of the self-locking groove and the hinge seat. In addition, the design of the boss can also increase the strength of the hinge structure to a certain extent and improve its bearing capacity.

[0024] Furthermore, according to the cabinet assembly provided by the embodiment of the second aspect of the utility model, by providing the above-mentioned hinge structure, the opening and closing process of the door body is smoother, thereby improving the user experience.

DETAILED DESCRIPTION

[0037] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0038] like Figures 1 to 8 As shown, the first embodiment of the utility model provides a hinge structure, including a hinge seat 100 and a plurality of hinge shafts 104; wherein, the hinge seat 100 is provided with a first connecting hole 102; the hinge shaft 104 is passed through the first connecting hole 102, and the hinge shaft 104 is used to adapt to the self-locking groove 128, and at least one hinge shaft 104 can be raised and lowered relative to the first connecting hole 102, and a flange portion 106 is provided on the hinge shaft 104, and a boss 110 is provided on the side of the flange portion 106 facing the self-locking groove 128, and an arc contact surface 112 is provided on the outer edge of the boss 110 facing the self-locking groove 128.

[0039] According to the hinge structure provided by the embodiment of the first aspect of the utility model, at least one hinge shaft 104 in the hinge structure can be adjusted up and down relative to the first connection hole 102. This design allows the height of the hinge to be fine-tuned as needed in actual applications to adapt to different installation environments and connection requirements, or to compensate for the installation deviation of the door body 132 caused by production errors, ensuring that the heights of the two door bodies 132 are consistent. This flexibility greatly enhances the versatility and adaptability of the hinge structure. The adaptive design of the hinge shaft 104 and the self-locking groove 128 enables the hinge structure to be automatically locked in a specific position to prevent accidental loosening or sliding. This self-locking function not only improves the stability and safety of the hinge structure, but also reduces the cumbersome operation caused by frequent adjustments. The boss 110 and the arc contact surface 112 on the outer edge of the hinge shaft 104 optimize the contact mode between the hinge structure and the self-locking groove 128. The arc contact surface 112 can provide a more uniform and stable contact force, reduce wear and noise, and enhance the reliability of the connection, avoiding the scratching phenomenon between the self-locking groove 128 and the hinge seat 100. In addition, the design of the boss 110 can also increase the strength of the hinge structure to a certain extent and improve its bearing capacity.

[0040] Please continue to see Figure 1 and Figure 2 In the hinge structure provided in the embodiment of the first aspect of the present invention, the hinge seat 100 is the basic part of the hinge structure, and a first connecting hole 102 is provided inside the hinge seat 100. The first connecting hole 102 is used to pass the hinge shaft 104 to ensure that the hinge shaft 104 can be firmly connected to the hinge seat 100.

[0041] The hinge shaft 104 passes through the first connection hole 102 of the hinge base 100 and is matched with the self-locking groove 128 on another component (such as the cabinet 130 or the frame). At least one hinge shaft 104 is designed to be adjustable relative to the first connection hole 102. This design allows the installer or user to fine-tune the hinge structure so that the door body 132 can adapt to different installation conditions or usage requirements.

[0042] It is understandable that when the sealing performance between the door body 132 and the cabinet body 130 decreases due to deformation or manufacturing errors, the relative height between the hinge shaft 104 and the hinge seat 100 can be changed by adjusting the lifting and lowering of the hinge shaft 104 relative to the first connecting hole 102. Since the relative height between the hinge shaft 104 and the hinge seat 100 changes, the relative position between the door body 132 and the self-locking groove 128 changes. Therefore, the relative position between the door body 132 and the cabinet body 130 can be adjusted, thereby changing the sealing performance between the door body 132 and the cabinet body 130, and at the same time, the self-closing function of the door body 132 can be achieved.

[0043] A flange portion 106 is arranged on the hinge shaft 104, and the outer edge portion of the flange portion 106 is designed as a circular arc transition surface 108. It should be noted that the outer edge portion of the flange portion 106 refers to the outer edge portion of the flange portion 106 in the radial direction. With such a setting, the outer edge portion of the flange portion 106 will not interfere with the self-locking groove 128 during the rotation of the door body 132. In addition, when a tool such as a wrench is used to adjust the relative position of the hinge shaft 104 and the first connecting hole 102, the circular arc transition surface 108 is provided to prevent the wrench from damaging the outer edge of the flange portion 106, and to prevent the coating on the outer edge of the flange portion 106 from falling off, thereby effectively ensuring the service life of the flange portion 106. At the same time, with the provision of the circular arc transition surface 108,

[0044] A boss 110 is disposed on a side of the flange portion 106 facing the self-locking groove 128 , and an arc contact surface 112 is disposed on an outer edge of the boss 110 facing the self-locking groove 128 .

[0045] The boss 110 is arranged on the side of the flange portion 106 of the hinge shaft 104 facing the self-locking groove 128, and the surface of the boss 110 is arranged as a circular arc contact surface 112. It can be understood that the purpose of the arrangement of the circular arc contact surface 112 is to reduce the friction between the flange portion 106 and the notch end surface of the self-locking groove 128 during the rotation of the door body 132. That is, by adding the boss 110 and setting the surface of the boss 110 as the circular arc contact surface 112, the contact area between the hinge shaft 104 and the self-locking groove 128 is increased, and the pressure is reduced, thereby preventing the hinge shaft 104 from scratching the self-locking groove 128.

[0046] See also Figure 3 and Figure 4 The arc contact surface 112 on the boss 110 further reduces the friction between the hinge shaft 104 and the self-locking groove 128. When the door body 132 rotates, the arc contact surface 112 contacts the notch end surface of the self-locking groove 128, making the sliding smoother.

[0047] In the embodiment of the utility model, the design of the boss 110 not only optimizes the friction force, but also enhances the stability of the hinge structure. The contact area between the boss 110 and the notch end surface of the self-locking groove 128 is reduced, which reduces the friction force between the two, making the door body 132 smoother during rotation, reducing jamming and friction noise.

[0048] In addition, the design of the boss 110 also increases the stability of the hinge structure, making the door body 132 more stable during opening and closing. Due to the reduced friction and improved stability, the service life of the hinge structure is extended.

[0049] Optionally, a limiting groove 114 is provided on the hinge shaft 104 of the flange portion 106 away from the self-locking groove 128 , and a limiting member 116 is disposed in the limiting groove 114 . The hinge shaft 104 is adapted to be limited in its relative position to the hinge seat 100 by the limiting member 116 .

[0050] See also Figure 4 A slot is provided on the hinge shaft 104 on the flange portion 106 away from the self-locking slot 128. The slot can be completely provided along the circumference of the hinge shaft 104, or can be provided at intervals along the circumference of the hinge shaft 104. The slot can form the above-mentioned limit slot 114, in which a limit member 116 is provided. The limit member 116 mentioned here can be an annular sheet.

[0051] It can be understood that the connection reliability between the hinge shaft 104 and the first connecting hole 102 mainly depends on the thread engagement height and thread accuracy of the hinge shaft 104 and the first connecting hole 102. The smaller the engagement height between the hinge shaft 104 and the first connecting hole 102, the smaller the bite force between the hinge shaft 104 and the first connecting hole 102. Too small a bite force may cause the hinge shaft 104 to fatigue and fall off during the long-term opening and closing of the door. Therefore, in order to prevent the above situation from occurring, a limit groove 114 is provided on the hinge shaft 104, and a limit member 116 is added to the limit groove 114, so that during the rotation of the door body 132, the position of the hinge shaft 104 relative to the first connecting hole 102 remains unchanged, thereby ensuring that the hinge shaft 104 will not be affected during the rotation of the door body 132. In addition, the limiting member 116 can also effectively limit the installation position of the hinge shaft 104 and the first connection hole 102, thereby preventing the hinge shaft 104 from coming out of the first connection hole 102. In order to adapt to door bodies 132 of different sizes and achieve adjustment of different heights, a plurality of limiting grooves 114 can be provided on the hinge shaft 104. In actual use, the installer or user can flexibly select according to actual needs.

[0052] Optionally, a plurality of operating surfaces 118 for matching with operating tools are further provided on the outer edge of the flange portion 106 , and the arc transition surface 108 is formed between two adjacent operating surfaces 118 .

[0053] See also Figure 3 , a plurality of operating surfaces 118 are provided on the outer edge of the flange portion 106. These operating surfaces 118 are usually flat or slightly inclined so as to be compatible with various operating tools (such as wrenches, etc.). By providing a plurality of operating surfaces 118 on the outer edge of the flange portion 106, operators can use various tools for operation more conveniently, thereby greatly improving the efficiency of installation and maintenance. The design of the operating surface 118 not only provides convenience for operation, but also can enhance the stability of the hinge structure to a certain extent. By reasonably allocating the position and number of the operating surfaces 118, it can be ensured that the hinge structure can remain stable when subjected to external forces to avoid deformation or damage.

[0054] The number of the operating surfaces 118 may be, for example, six, and the angle between two adjacent operating surfaces 118 is degrees.

[0055] Optionally, the hinge seat 100 is further provided with a second connection hole 120 communicating with the first connection hole 102 , and a fastener 122 is passed through the second connection hole 120 , and the fastener 122 is suitable for abutting against the hinge shaft 104 .

[0056] See also Figure 1 A second connection hole 120 communicating with the first connection hole 102 is provided on the hinge seat 100 , and the second connection hole 120 may be a bolt hole.

[0057] The fastener 122 is inserted into the second connection hole 120, and its end can abut against the hinge shaft 104. The fastener 122 is usually an adjustable component, such as a bolt, a nut, etc., and the pressure of the fastener 122 abutting against the hinge shaft 104 can be adjusted by rotation or other means.

[0058] When the position of the hinge shaft 104 needs to be fixed or adjusted, it can be achieved by adjusting the fastener 122. For example, when the door body 132 is deformed or rotates poorly during use, the position of the door body 132 can be adjusted by adjusting the installation position of the hinge shaft 104 relative to the first connection hole 102, and then tightening the fastener 122 to increase its abutment force on the hinge shaft 104, so that the relative position of the hinge shaft 104 and the first connection hole 102 is locked.

[0059] The fastener 122 is abutted against the hinge shaft 104, which ensures that the hinge shaft 104 remains stable when subjected to external forces, avoiding deformation or damage. This design makes the door body 132 more stable during opening and closing, improving the comfort of use. The adjustability of the fastener 122 allows the fastener 122 to be adjusted to achieve the desired position of the hinge shaft 104 or the desired position of the hinge shaft 104.

[0060] Optionally, an internal thread is provided in the first connecting hole 102 , a thread segment matching the internal thread is provided on the hinge shaft 104 , and the fastener 122 is suitable for abutting against the thread segment.

[0061] An internal thread is provided in the first connecting hole 102, and a thread segment matching the internal thread is added to the hinge shaft 104. This design enables the fastener 122 to directly abut against the thread segment of the hinge shaft 104 by threaded connection, thereby achieving more stable and accurate fixation and adjustment of the hinge shaft 104.

[0062] An internal thread is processed in the first connection hole 102, and a thread segment matching the internal thread is provided on the hinge shaft 104. The thread segment is integrally formed with other parts of the hinge shaft 104, or is firmly connected to the hinge shaft 104 in other ways. Through the threaded cooperation between the thread segment and the internal thread, on the one hand, the self-locking of the hinge shaft 104 can be achieved, and on the other hand, it is also conducive to fine-tuning the hinge shaft 104 relative to the first connection hole 102. When the fastener 122 abuts against the thread segment, the hinge shaft 104 can be locked by the fastener 122, further improving the connection stability of the hinge shaft 104 relative to the first connection hole 102.

[0063] Optionally, the hardness of the fastener 122 is less than the hardness of the hinge shaft 104 .

[0064] It can be understood that when the fastener 122 contacts the threaded segment, the fastener 122 applies a locking force to the threaded segment. Since the hardness of the fastener 122 is smaller than that of the threaded segment, the wear between the fastener 122 and the threaded segment can be alleviated, thereby avoiding the risk of wear and damage to the threaded segment caused by the contact between the fastener 122 and the threaded segment, thereby extending the service life of the articulated shaft 104.

[0065] In the embodiment of the utility model, the fastener 122 includes at least one of a copper pad, an aluminum pad, a silver pad and a tin pad, which can effectively protect the threaded section during the fastening process of the fastener 122.

[0066] Of course, the fastener 122 can also be two of the copper pad, aluminum pad, silver pad and tin pad (e.g., the fastener 122 can be a combination of a copper pad and an aluminum pad). The fastener 122 can also be three of the copper pad, aluminum pad, silver pad and tin pad (e.g., the fastener 122 can also be a combination of a copper pad, aluminum pad and silver pad). The fastener 122 can also be a combination of a copper pad, aluminum pad, silver pad and tin pad. The structure of the fastener 122 can be set according to actual needs and is not limited here.

[0067] Optionally, the fastener 122 includes a main body portion 124 and an abutment portion 126 ; the main body portion 124 is disposed through the second connection hole 120 ; and the abutment portion 126 is suitable for abutting against the hinge shaft 104 .

[0068] like Figure 5 As shown, in the embodiment of the utility model, the fastener 122 includes a body portion 124 and an abutment portion 126. The body portion 124 is threadedly connected to the second connection hole 120. The connection method is simple and convenient for disassembly of the fastener 122. Among them, the thread bottom diameter of the body portion 124 is greater than or equal to the width of the abutment portion 126. The second connection hole 120 is greater than or equal to the diameter of the abutment portion 126, and the abutment portion 126 can stably pass through the second connection hole 120 and abut against the hinge shaft 104. At the same time, the larger thread bottom diameter can also improve the connection strength between the body portion 124 and the second connection hole 120, thereby effectively preventing the body portion 124 from loosening under vibration or external force.

[0069] The abutment portion 126 abuts against the hinge shaft 104, and the width of the abutment portion 126 can be understood as the width perpendicular to the axial direction of the fastener 122. When the abutment portion 126 is a cylindrical structure, the width of the abutment portion 126 is the diameter of the cylindrical structure, that is, the thread bottom diameter of the main body 124 is greater than or equal to the diameter of the abutment portion 126. Of course, the structure of the abutment portion 126 is not limited to a cylindrical structure, and the abutment portion 126 can also be a prism structure, a rectangular body structure, etc., which can be set according to actual needs.

[0070] The thickness of the abutment portion 126 is greater than or equal to 1 mm and less than or equal to 5 mm. The structure of the abutment portion 126 is simple. The abutment portion 126 within this thickness range can not only better disperse the load and provide sufficient strength and stability, but also help control the weight of the fixing, thereby contributing to lightweight design.

[0071] In some other embodiments, the abutment portion 126 and the main body portion 124 of the fastener 122 may also be an integral structure, that is, the abutment portion 126 is integrally formed on the main body portion 124; the abutment portion 126 and the main body portion 124 may also be fixedly connected, such as welding, crimping, etc.

[0072] like Figures 6 to 8 As shown, the second aspect of the utility model provides a cabinet assembly, including a cabinet body 130 and a door body 132 rotatably connected to the cabinet body 130, one of the cabinet body 130 and the door body 132 is connected with the hinge structure as mentioned above, and the other one of the cabinet body 130 and the door body 132 is provided with a self-locking groove 128.

[0073] According to the cabinet assembly provided by the embodiment of the second aspect of the utility model, by providing the above-mentioned hinge structure, the opening and closing process of the door body 132 is smoother, thereby improving the user experience. At the same time, during the installation and use of the cabinet body 130 and the door body 132, the height of the door body 132 can be fine-tuned to ensure that the heights of the two door bodies 132 are consistent, thereby ensuring the sealing performance between the door body 132 and the cabinet body 130, and ensuring the realization of the self-closing function of the door body 132.

[0074] In the embodiments of the present invention, the cabinet assembly can be a refrigeration device such as a refrigerator, a freezer, a fresh-keeping cabinet, a cold chain carriage, etc. The cabinet assembly can also be a display cabinet, a cupboard, etc. The cabinet assembly can also be a household appliance such as a microwave oven and a dishwasher. Of course, the cabinet assembly can also be other structures having a cabinet body 130 and a door body 132 connected by a hinge assembly, which are not listed one by one here.

[0075] like Figure 6 and Figure 7 As shown, taking the hinge assembly connected to the cabinet 130 as an example, the hinge seat 100 of the hinge assembly is connected to the cabinet 130, and the hinge shaft 104 is adapted to the self-locking groove 128 of the door body 132. By raising and lowering the hinge shaft 104, the hinge shaft 104 abuts against the self-locking groove 128 of the door body 132, so that the door body 132 moves relative to the hinge seat 100, thereby realizing the height adjustment of the door body 132.

[0076] The hinge base 100 is detachably connected to the cabinet 130, and the connection between the hinge base 100 and the cabinet 130 is simple and convenient, and has a wide range of applications. The hinge base 100 can also be detachably connected to the cabinet 130 by means of fixing parts such as bolts and screws, which is easy to disassemble and replace. Figure 1 As shown, the hinge base 100 is provided with a fixing hole 134 , and fixing members such as bolts and screws can be inserted into the fixing hole 134 to achieve the connection between the hinge base 100 and the cabinet 130 .

[0077] Optionally, the door body 132 is suitable for switching between an open position and a closed position relative to the cabinet body 130; the self-locking groove 128 includes a self-locking section 136 and a sliding section 138 that are interconnected. In the open position and the closed position, the hinge shaft 104 is in the self-locking section 136, and in the process of switching between the open position and the closed position, the hinge shaft 104 is in the sliding section 138, and the thickness of the groove side wall of the sliding section 138 is greater than the thickness of the groove side wall of the self-locking section 136.

[0078] like Figure 8 As shown, in the embodiment of the utility model, the hinge structure is particularly suitable for the connection between the door body 132 and the cabinet body 130, allowing the door body 132 to smoothly switch between the open position and the closed position. In order to achieve this function, the self-locking groove 128 is designed to have two interconnected sections: a self-locking section 136 and a sliding section 138.

[0079] When the door body 132 is in the open position or the closed position, the hinge shaft 104 will be located in the self-locking section 136. The design of the self-locking section 136 allows the hinge shaft 104 to remain stable when in a fixed position, preventing the door body 132 from being accidentally opened or closed.

[0080] When the door body 132 switches from the open position to the closed position (or from the closed position to the open position), the hinge shaft 104 passes through the sliding section 138. The sliding section 138 provides enough space to allow the hinge shaft 104 to slide freely during the movement of the door body 132.

[0081] The thickness of the groove sidewall of the sliding section 138 is designed to be greater than the thickness of the groove sidewall of the self-locking section 136. This design makes the sliding section 138 have higher strength, can withstand the friction and impact force generated by the hinge shaft 104 during the sliding process, and prolong the service life of the hinge structure.

[0082] See also Figure 8By setting a self-locking section 136 at the opening and closing positions of the door body 132, it is ensured that the door body 132 remains stable in a static state. The self-locking section 136 can realize self-locking of the door body 132, thereby ensuring the sealing performance of the door body 132 and the cabinet body 130. The design of the sliding section 138 allows the door body 132 to switch smoothly during the opening and closing process, reducing friction and resistance, and improving the user experience. The thicker groove side walls of the sliding section 138 can withstand greater impact and friction, reducing the wear of the hinge structure, thereby extending the overall service life. The design of the entire hinge structure ensures the stability and safety of the door body 132 during the opening and closing process, and avoids damage or accidents caused by accidental movement.
