Description

Technical Field

[0001] The present application relates to the technical field of furniture accessories, and in particular to a top and bottom hinge. Background Art

[0002] A hinge is a mechanical device used to connect two solid bodies and allow rotation between them.

[0003] Floor hinges are usually used in opening and closing structures such as doors and windows to ensure the stability of the opening and closing of doors and windows.

[0004] A Chinese patent application with publication number CN216767063U discloses a heavy-duty top-bottom hinge, which includes a crank arm, a fixed shell, a movable shell, a transmission arm, an adjustment rod and at least two springs installed in the fixed shell; the fixed shell is connected to the movable shell through the crank arm, the transmission arm is movably arranged in the fixed shell, one side of which abuts against the spring, and the crank arm can slidably abut on the other side of the transmission arm; the adjustment rod is installed in the movable shell and connected to the crank arm, and the adjustment rod is configured to be able to drive the crank arm to move along the axial direction of the adjustment rod.

[0005] In the related art, because the design of the product, whether in terms of buffer structure or spring structure, is designed through a layout in which the direction of the force arm is the same as the depth direction of the hinge box, the problem with such a design is that, during the design process of the hinge box, due to the requirements of the spring force and the buffer force, the hinge box needs to be designed to be relatively deeper. When installed on the cabinet door, a deeper installation groove needs to be opened at the position of the cabinet door corresponding to the hinge box. The deeper the installation groove, the greater the impact on the strength of the cabinet door, and it also increases the difficulty of processing. Summary of the invention

[0006] The purpose of this application is to overcome the above technical problems and provide a top and bottom hinge, which adopts the following technical solutions: A top-bottom hinge comprises a hinge ring, a hinge box, a main hinge arm and an auxiliary hinge arm; One end of the main hinge arm is hinged to the hinge ring, the other end of the main hinge arm is hinged to the hinge box, a buffer part is arranged on one side of the main hinge arm, and an energy storage part is arranged on the other side of the main hinge arm; One end of the auxiliary hinge arm is hinged to the hinge ring, and the other end of the auxiliary hinge arm is hinged to the hinge box; A buffer member is installed in the hinge box, the buffer member is arranged along the depth direction of the hinge box, and a buffer end of the buffer member contacts the buffer portion; A spring member is installed in the hinge box, the spring member is arranged along the length direction of the hinge box, and the elastic end of the spring member contacts the energy storage part; The hinge box is divided into a first box body and a second box body. The first box body covers the second box body. The first box body and the second box body are connected by a connecting piece. The connecting piece is detachably connected to the hinge box.

[0007] By adopting the above technical solution, the main hinge arm and the auxiliary hinge arm work together, and cooperate with the functions of the buffer and the spring, which greatly improves the stability and durability of the top and bottom hinges when opening and closing. The design of the buffer along the depth direction of the hinge box, combined with the layout of the spring along the length direction, makes the overall structure more streamlined and compact, and significantly reduces the space required for the hinge box. This improvement effectively reduces the excavation depth of the cabinet door installation groove, simplifies the processing technology, avoids excessive weakening of the cabinet door strength, and also reduces the possibility of deviation during the assembly process, further ensuring the firmness of the hinge installation. In addition, the optimized design greatly improves the efficiency of material use and reduces production costs. It is especially suitable for thin top or bottom plate application scenarios, showing higher economic value and wide applicability. In addition, the hinge box is designed as a combination of the first box body and the second box body, and the two are detachably connected by a connector. This structure not only facilitates the assembly and later maintenance of the hinge box, but also when the internal accessories of the hinge box fail or are damaged, they can be easily disassembled and replaced, avoiding the problem of the traditional method of forcibly breaking the hinge box and causing the entire hinge box to be scrapped, significantly improving production efficiency and effectively reducing maintenance costs. In addition, the cover design between the first box body and the second box body can also ensure the stability and sealing of the internal components, thereby effectively preventing the intrusion of external dust or other impurities, and ensuring the long-term stable operating performance of the top and bottom hinges.

[0008] Preferably, the hinge ring is provided with a first accommodating portion, and the first accommodating portion is used to accommodate the auxiliary hinge arm and the buffer portion of the main hinge arm to the connecting portion between the main hinge arm and the hinge ring.

[0009] By adopting the above technical solution, the first accommodating portion can effectively integrate the spatial layout of the buffer portion of the auxiliary hinge arm and the main hinge arm, making the internal structure of the hinge ring more compact. This design not only reduces the risk of interference between components, but also improves the space utilization of the overall structure, thereby further optimizing the size design of the hinge box, reducing the requirements for the depth of the cabinet door installation groove, and improving the simplicity and reliability of the assembly process.

[0010] Preferably, the hinge ring is provided with a second accommodating portion, a hinge ring adjusting member is provided in the second accommodating portion, the hinge ring adjusting member is slidably connected to the hinge ring, a sliding-assisting portion is provided on the hinge ring, the sliding-assisting portion is penetrated by the hinge ring adjusting member, and the hinge ring adjusting member is slidably connected to the sliding-assisting portion.

[0011] By adopting the above technical solution, the optimized design of the internal structure of the hinge ring is achieved. Specifically, by providing a second accommodating portion on the hinge ring and arranging the hinge ring adjustment member and the sliding aid portion therein, the adjustment function of the hinge ring is enhanced, while ensuring smooth sliding cooperation between the components. This design not only improves the assembly accuracy and stability of the top and bottom hinges, but also facilitates later maintenance and adjustment, effectively improving the user experience of the product.

[0012] Preferably, the hinge adjustment member includes an adjustment portion and an adjustment support portion installed in the second accommodating portion; the sliding aid portion is passed through the adjustment support portion and is slidably connected to the adjustment support portion; the adjustment support portion has a first displacement portion and a second displacement portion, and the adjustment portion has a connecting end and a first pushing portion; the connecting end of the adjustment portion passes through the first displacement portion, the second displacement portion and the hinge in sequence, and the first pushing portion is in contact with the first displacement portion, and the connecting end of the adjustment portion is rotatably connected to the hinge.

[0013] By adopting the above technical solution, the cooperation between the hinge ring adjustment member and the sliding aid part of the top and bottom hinge realizes the precise position adjustment function. When the adjustment part is rotated, due to the interaction between the first push part and the first displacement part of the adjustment support part, the rotational movement of the adjustment part is converted into a linear push, which prompts the adjustment support part to move smoothly along the second displacement part set by itself, thereby changing the position of the cabinet door connected to the hinge ring. In this process, the first displacement part and the second displacement part together constitute a stable fulcrum to ensure that the force of the entire adjustment process is balanced and precisely controllable. At the same time, the sliding connection formed between the sliding aid part and the adjustment support part effectively reduces the friction resistance and provides a clear direction guidance, which greatly improves the smoothness of operation. In addition, the design of the connection end of the adjustment part and the hinge ring to realize the rotational connection further enhances the adjustment flexibility, so that it can quickly respond and adjust the working state according to different use environments, significantly improving the convenience of operation, adaptability and overall reliability of the top and bottom hinge.

[0014] Preferably, a first support seat and a second support seat are provided in the hinge box, the first support seat and the second support seat are arranged along the depth direction of the hinge box, and the first support seat is slidably connected to the hinge box; one end of the second support seat is hinged to the first support seat, and the other end is slidably connected to the first support seat; one end of the main hinge arm is hinged to the second support seat, and one end of the auxiliary hinge arm is hinged to the second support seat, the buffer member is installed on the second support seat, and the spring member is installed on the second support seat, and one end is connected to the first support seat.

[0015] By adopting the above technical solution, the first support seat and the second support seat of the top and bottom hinge are arranged along the depth direction of the hinge box, and the first support seat is slidably connected to the hinge box. This design can effectively adjust the spatial layout of the internal structure of the hinge, thereby optimizing the size of the hinge box. One end of the second support seat is hinged to the first support seat, and the other end is slidably connected to it. This method enhances the linkage and flexibility between the support seats, and ensures the stability of the main hinge arm and the auxiliary hinge arm during movement. The main hinge arm and the auxiliary hinge arm are both hinged to the second support seat, so that the two can achieve precise motion control in a limited space. At the same time, the buffer is installed on the second support seat, and the method of connecting one end of the spring member to the first support seat is used to achieve effective force transmission and energy storage, thereby improving the overall functional reliability and service life of the top and bottom hinge.

[0016] Preferably, the first support seat is provided with a plurality of limiting parts, and a plurality of transverse guide sliding parts are provided on the shell wall of the hinge box, and the plurality of limiting parts are respectively slidably connected with the plurality of transverse guide sliding parts; the first support seat has a third displacement part; a transverse adjustment part is provided on the hinge box, and the middle part of the transverse adjustment part is clamped on the hinge box and is rotatably connected with the hinge box, one end extends into the third displacement part and contacts with the third displacement part, and the other end is located outside the hinge box.

[0017] By adopting the above technical solution, the sliding connection between the first support seat and the hinge box can be precisely controlled. Specifically, the cooperation between multiple limiting parts and multiple horizontal guide sliding parts ensures the stability and accuracy of the first support seat during the lateral movement, avoiding unnecessary shaking or deviation. At the same time, the design of the horizontal adjustment member makes the position adjustment of the first support seat more flexible and convenient. It only needs to rotate the horizontal adjustment member to push the third displacement part to drive the first support seat to move, thereby realizing the fine-tuning function of the position of the first support seat. This design not only improves the compactness of the overall structure of the top and bottom hinge, but also enhances its reliability and adaptability in practical applications.

[0018] Preferably, a vertical guide sliding portion and a vertical adjustment member rotatably connected to the first support seat are provided on the first support seat, one end of the vertical adjustment member is passed through the first support seat and is clamped on the second support seat; a vertical guide member is provided on the second support seat, one end of the vertical guide member is passed through the first support seat and the vertical guide sliding portion in sequence.

[0019] By adopting the above technical solution, the matching accuracy and adjustment flexibility between the first support seat and the second support seat in the top and bottom hinge are significantly enhanced. Specifically, the ingenious design of the vertical guide slide and the vertical guide member ensures the smooth movement of the second support seat in the vertical direction, effectively preventing the offset or jamming problems that may occur during operation. At the same time, the addition of the vertical adjustment member greatly improves the accuracy of position adjustment, and can easily meet the needs of various work scenarios. The operator only needs to rotate the vertical adjustment member to efficiently drive the second support seat to complete the position change, and then realize the fine regulation of the connection between the main hinge arm and the auxiliary hinge arm, and finally achieve the purpose of optimizing the opening and closing state of the cabinet door. The above innovations work together to greatly enhance the working stability and durability of the top and bottom hinge.

[0020] Preferably, the thickness of the hinge box body ranges from 8.8 to 10 mm, the height of the hinge box ranges from 32 to 35 mm, and the width of the hinge box ranges from 60 to 65 mm.

[0021] By adopting the above technical solution, the size of the hinge box is significantly reduced, with the thickness reduced to 8.8 to 10 mm, the height reduced to 32 to 35 mm, and the width reduced to 60 to 65 mm. This design can not only adapt to top plates or bottom plates with a thickness of only 16 mm, but also effectively reduce the impact on the structural strength of the cabinet door and simplify the installation process. Compared with traditional products, for cabinet doors with a door height of less than 1.6m, the original top plate / bottom plate needs to be 18mm thick and the hinge box thickness is 10mm, but now the overall design is thinner; for doors higher than 1.6m, a 20mm top plate / bottom plate and a 12mm thick hinge box were originally required. The current design also greatly reduces material costs and assembly complexity, showing higher economy and wide applicability.

[0022] Preferably, a resistance portion is provided on the surface of one end of the hinge box, and at least four groups of resistance portions are provided; the hinge box is provided with a first fixing portion, and the first fixing portion is located on the hinge box at one end of the resistance portion; the hinge ring is provided with a second fixing portion and a third fixing portion, and the second fixing portion is located on one side of the first accommodating portion, and the third fixing portion is located on one side of the second accommodating portion.

[0023] By adopting the above technical solution, the setting of the resistance part can increase the friction between the hinge box and the installation surface, effectively prevent the top and bottom hinges from loosening or unexpectedly rotating during use, and improve stability. The design of multiple groups of resistance parts further enhances this anti-loosening effect. The arrangement of the first fixing part facilitates the fixed connection between the hinge box and other components, and improves assembly efficiency and reliability. The second fixing part and the third fixing part are respectively located on one side of the first accommodating part and the second accommodating part, which not only strengthens the structural strength of the hinge ring itself, but also optimizes the spatial layout, making the installation of each component more compact and orderly, reducing the overall volume, and improving the applicability and aesthetics of the product.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. The main hinge arm and the auxiliary hinge arm work together with the functions of the buffer and spring parts to greatly improve the stability and durability of the top and bottom hinges when opening and closing. The design of the buffer along the depth direction of the hinge box, combined with the layout of the spring parts along the length direction, makes the overall structure more streamlined and compact, and significantly reduces the space required for the hinge box. This improvement effectively reduces the excavation depth of the cabinet door installation groove, simplifies the processing technology, avoids excessive weakening of the cabinet door strength, and also reduces the possibility of deviation during the assembly process, further ensuring the firmness of the hinge installation.

[0025] 2. The sliding and articulated cooperation between the first support seat and the second support seat makes the movement of the main hinge arm and the auxiliary hinge arm more flexible and reliable, while optimizing the internal space utilization and enhancing the stability of the overall structure; 3. The design of the first and second accommodating parts of the hinge ring can not only better constrain the movement paths of the main hinge arm and the auxiliary hinge arm, but also protect the buffer part from external environmental interference and extend its service life; 4. The combined design of the horizontal adjustment piece and the vertical adjustment piece facilitates the precise adjustment of the relative positions of the components in the hinge box, thus improving the adaptability and installation accuracy of the top and bottom hinge in different application scenarios; 5. The hinge box is divided into a first box body and a second box body and is disassembled and connected through a connector. This modular design facilitates production and maintenance, and also supports quick replacement of parts, reducing maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

The elastic end of the spring member 6 contacts the energy storage part 32.

[0031] Specifically, when the door leaf is pushed open by external force, the lever principle pushes the corresponding part so that the spring that was originally in a static state begins to be stretched to accumulate potential kinetic energy. At the same time, the buffer unit is used to mitigate the negative impact of instantaneous drastic changes, thereby avoiding excessive wear of components, extending service life, and improving the overall reliability level.

[0032] Specifically, the hinge ring 1, the main hinge arm 3 and the auxiliary hinge arm 4 are respectively made of stainless steel alloy materials with high corrosion resistance and high strength, which can be used for a long time in harsh environmental conditions without damage, further improving the service life and stability of the top and bottom hinges. The buffer 5 is installed in the hinge box 2 and arranged along the depth direction of the hinge box 2. Its function is to absorb the impact force generated during the opening and closing process. The buffer part 31 is specifically a buffer protrusion convexly provided on the main hinge arm 3.

[0033] In this embodiment, the buffer 5 is specifically a hydraulic damper, and in other embodiments it can be a rubber block or a spring. The hydraulic damper can better control the speed and stability, so as to withstand a certain pressure without being easily damaged or deformed.

[0034] On the other hand, the spring member 6 is distributed along the length direction of the hinge box 2 and is responsible for storing energy and releasing it when needed to help the closing action to be completed smoothly.

[0035] See also Figure 1 and Figure 2 Furthermore, the hinge ring 1 is provided with a first accommodating portion 11 and a second accommodating portion 12, the first accommodating portion 11 is used to accommodate the auxiliary hinge arm 4 and the buffer portion 31 of the main hinge arm 3 to the connecting portion between the main hinge arm 3 and the hinge ring 1.

[0039] When the adjusting part 14 is rotated, due to the interaction between the first pushing part 141 and the first displacement part 150 of the adjusting support part 15, the rotational movement of the adjusting part 14 is converted into a linear push, which causes the adjusting support part 15 to move smoothly along the second displacement part 151 provided by itself, thereby changing the position of the cabinet door 9 connected to the hinge ring 1. In this process, the first displacement part 150 and the second displacement part 151 together constitute a stable fulcrum, ensuring that the entire adjustment process is balanced and precisely controllable. At the same time, the sliding connection formed between the sliding aid part 13 and the adjusting support part 15 effectively reduces the friction resistance and provides clear direction guidance, greatly improving the smoothness of operation.

This design can effectively adjust the spatial layout of the internal structure of the hinge, thereby optimizing the size of the hinge box 2.

[0043] See also Figure 2 and Figure 3 Further, the first support seat 21 is provided with a plurality of limiting portions 210, and a plurality of transverse guide slides 23 are provided on the shell wall of the hinge box 2, and the plurality of limiting portions 210 are respectively slidably connected with the plurality of transverse guide slides 23.

The energy storage part 32 is specifically a circular block protruding on the main hinge arm 3, and the contact end of the main hinge arm 3 and the spring member 6 is set as a circular block, which can make the output point of the reaction force of the spring member 6 follow the swing of the main hinge arm 3. Compared with the existing spring member 6 that is directly fixedly connected to the main hinge arm 3 and twisted with the swing of the main hinge arm 3, the output point of the reaction force cannot reach the maximum elastic force. The structure of the present application can output stably and provide strong support, so that the main hinge arm 3 can swing stably, and the life of the spring member 6 is also extended.

[0048] In other embodiments, the spring column is configured as a spring screw, and configuring the spring screw can fine-tune the elastic force value of the spring member 6 so that the swing of the main hinge arm 3 can be more stable.

[0050] Specifically, the resistance part 25 is a slanted piece protruding from the hinge box 2. At least four groups of resistance parts 25 are provided, which can effectively prevent the top and bottom hinges from loosening or unexpectedly rotating during use. The first fixing part 26 is a fixing seat extending along the length direction of the hinge box 2, and a through hole for screws to pass through is provided on the fixing seat. The second fixing part 16 and the third fixing part 17 are also fixing seats extending from the ends of the hinge ring 1, and a through hole for screws to pass through is also provided on the fixing seats. The arrangement of the first fixing part 26, the second fixing part 16 and the third fixing part 17 facilitates the fixed connection between the top and bottom hinges and other components, and improves assembly efficiency and reliability.

[0051] Furthermore, the hinge box 2 is divided into a first box body 27 and a second box body 28 . The first box body 27 covers the second box body 28 . The first box body 27 and the second box body 28 are connected via a connector 7 . The connector 7 is detachably connected to the hinge box 2 .

[0052] Specifically, the connecting member 7 includes a step nail, which is used to connect the first box body 27 and the second box body 28 of the hinge box 2. When the internal accessories of the hinge box 2 fail or are damaged, they can be easily disassembled and replaced, avoiding the problem of traditional rivet connection that needs to be forcibly broken, resulting in the entire hinge box 2 being scrapped, significantly improving production efficiency and effectively reducing maintenance costs.

[0053] In other embodiments, a mounting box 8 is further mounted on the hinge box 2. Mounting of the mounting box 8 can further protect the structural components in the hinge box 2 and the cabinet body 10, and extend the service life of the top and bottom hinges.

[0054] Furthermore, the thickness of the hinge box 2 body ranges from 8.8 to 10 mm, the height of the hinge box 2 ranges from 32 to 35 mm, and the width of the hinge box 2 ranges from 60 to 65 mm.

[0055] Specifically, the size of the hinge box 2 is significantly reduced, with the thickness reduced to 8.8 to 10 mm, the height reduced to 32 to 35 mm, and the width reduced to 60 to 65 mm. This design can not only adapt to the top plate or bottom plate with a thickness of only 16 mm, but also effectively reduce the impact on the structural strength of the cabinet door 9 and simplify the installation process. Compared with traditional products, for cabinet doors 9 with a door height of less than 1.6 meters, the original top plate / bottom plate needs to be 18 mm thick and the hinge box 2 is 10 mm thick, but now it is lighter and thinner as a whole; and for doors higher than 1.6 meters, a 20 mm thick top plate / bottom plate and a 12 mm thick hinge box 2 are originally required. The current design also greatly reduces the material cost and assembly complexity, showing higher economy and wide applicability.

[0056] In this embodiment, the hinge box 2 has multiple application sizes: Application 1: Hinge box 2 is not installed with installation box 8. The floor hinge is used for doors with a height less than 1.6m. The thickness of hinge box 2 is 8.8mm, which is suitable for a top plate / bottom plate with a minimum thickness of 16mm. The thickness of hinge box 2 on the market is 10mm, and the minimum thickness of the assembled top plate / bottom plate needs to reach 18mm. The length / height of hinge box 2 is 32mm. The hinge box 2 with this length / height is not easy to deviate when processing the slot hole on the top plate / bottom plate. Compared with the hinge box 2 on the market with a length / height of 42mm, which is easy to deviate when processing the slot hole on the top plate / bottom plate, the risk of hinge box 2 falling off during installation is reduced; Application 2: The hinge box 2 is equipped with the installation box 8. The top and bottom hinges are used for doors with a height greater than 1.6m. The thickness of the hinge box 2 is 10mm, which is suitable for a top plate / bottom plate with a minimum thickness of 18mm. The installation box 8 can better protect the cabinet 10. The thickness of the hinge box plus the installation box 8 on the market is 12mm, and the minimum thickness of the assembled top plate / bottom plate needs to reach 20mm. The length / height of the hinge box 2 is 35mm. The hinge box 2 at this length / height is not easy to deviate when processing the slot holes on the top plate / bottom plate. Compared with the hinge box 2 on the market with a length / height of 45mm, the slot holes on the top plate / bottom plate are easily deviated, resulting in a weakened strength of the top plate / bottom plate, which reduces the risk of the hinge box 2 falling off during installation.

[0057] The present application provides a method for installing a top and bottom hinge, comprising the following steps: S1, install the hinge ring 1 and hinge the main hinge arm 3 and the auxiliary hinge arm 4 to the hinge ring 1 and the hinge box 2 respectively, and fix the hinge box 2 to a preset position on the cabinet 10; S2, adjust the position of the main hinge arm 3 so that the door panel on the hinge ring 1 is in a position that fits the cabinet 10, and use the horizontal adjustment member 24 and the vertical adjustment member 213 to fine-tune the position of the main hinge arm 3; S3, test whether the hinge moves smoothly and smoothly, and repeat step S2 if necessary to further accurately position it; S4. After confirming that the installation is complete, tighten each component to ensure that it is stable and reliable.

[0058] The above method greatly improves the installation efficiency while ensuring the final assembly quality by rationally planning the key points of operation at each stage, overcoming the problem of the original process being complicated and prone to errors.
