Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a mounting piece for a hinge base and a hinge with switchable bending arms. Background Art

[0002] A hinge is a mechanical device that connects two solids and allows them to rotate around a common axis. In daily life, hinges are widely used in furniture, doors and windows, transportation and other fields. They are the key to ensure that door panels and side panels can rotate smoothly. The hinge cup is connected to the door panel, and the hinge base is connected to the side panel. Depending on the installation position of the door panel and the side panel, the hinge has three types of curved arms: small bend, medium bend and large bend. The difference between different types of curved arm hinges is that when the hinge is opened, the vertical distance between the hinge cup and the base is different;

[0003] In the prior art, hinges with different bending arm types need to be realized by changing the bending angle of the hinge arm. The same functional hinge needs to design three hinge arms with different bending angles to correspond. This process involves the design and production of matching hinge arm molds, which leads to a significant increase in production costs. The production of hinge arms with different bending angles requires a certain amount of debugging and preparation time, which extends the production cycle and reduces production efficiency. Secondly, hinges with different bending arm types need to be separately managed in inventory and planned in production, which makes the production process more complicated. After the bending structure of the hinge arm is processed, the bending arm type of the hinge is fixed, and hinges with different bending arm types cannot be switched and adjusted. Once market demand changes, it is difficult for enterprises to respond quickly, which affects product competitiveness. Furthermore, during installation, if mismatched bending arm hinges are used, the gap between the door panel and the side panel will not match the design, which will directly affect the normal opening and closing of the door panel and the user experience.

[0034] Example 1: Figure 1-5As shown, a mounting piece for a hinge base 5 comprises a main body 1, a top wall of the main body 1 is provided with a mounting groove 101 for assembling the hinge base 5, the main body 1 is provided with a mounting hole 102 for penetrating the fixing screw of the hinge base 5, the mounting hole 102 is arranged to penetrate from the bottom wall of the mounting groove 101, the bottom wall of the mounting groove 101 abuts against the bottom wall of the hinge base 5, and is connected to the hinge base 5 by providing the mounting groove 101, thereby increasing the vertical distance between the hinge cup 2 and the base 5, thereby changing the bending arm type of the hinge, and during design and production, a small bending hinge is designed and produced, and a medium bending hinge and a large bending hinge are obtained by installing a mounting piece on the hinge base 5, the hinge base 5 is assembled in the mounting groove 101, displacement of the hinge after installation is prevented, and the stability of the hinge installation is improved, the mounting piece is provided with the mounting hole 102, and during the hinge installation, by selecting a suitable The fixing screws of different lengths are successively passed through the mounting hole 102 of the hinge base 5, the mounting hole 102 of the mounting piece, and the side panel, so as to connect the hinge to the side panel. By adding the mounting pieces, hinges of different arm types can be assembled without changing the design of the hinge itself, thereby improving the versatility of the hinge. There is no need to design and produce hinges separately for each arm type. The design standards of the hinges are unified, making the product design more modular and easy to manage and produce. It is only necessary to produce small-bend hinges and match them with different numbers of mounting pieces, thereby reducing mold costs and production costs, and reducing the number of hinges of different arm types that need to be stored. Only small-bend hinges and mounting pieces need to be stocked, thereby reducing inventory pressure and inventory costs. Secondly, the mounting pieces make on-site installation more flexible and quick. According to actual needs, the arm type of the hinge can be adjusted by adding or reducing mounting pieces.

[0035] It is worth mentioning that hinges can be divided into small, medium and large types according to the different bending arms. Hinges with different bending arms are suitable for different installation environments and design requirements. Small bending is suitable for occasions where the distance between the door panel and the edge of the side panel is small, such as ordinary indoor doors; medium bending is suitable for occasions where the distance between the door panel and the frame side panel is moderate, such as most furniture doors; large bending is suitable for occasions where the distance between the door panel and the edge of the side panel is large, such as most cabinet doors.

[0036] When installing the hinge, the installer needs to connect the base 5 of the hinge with the side panel of the cabinet, and the hinge cup 2 of the hinge with the door panel. Usually the side panel is perpendicular to the bottom surface. If the connection between the mounting seat and the hinge base 5 is loose, it is easy for the mounting piece to separate from the hinge and fall off during the installation process. In order to solve the above technical problems and improve the assembly stability of the mounting piece and the hinge base 5, the inner wall of the assembly groove 101 is arranged along the outer wall of the hinge base 5, and the inner wall of the assembly groove 101 is snap-fitted and assembled with the hinge base 5. By snap-fitting the mounting piece with the hinge base 5, it is convenient to assemble the mounting piece on the hinge. When the installer is installing it, the mounting piece is not easy to fall off, thereby improving the assembly stability and reliability of the mounting piece and the hinge base 5.

[0037] In terms of the specific structure of the snap-fit ​​assembly between the hinge base 5 and the mounting piece, the inner wall of the assembly groove 101 is provided with a plurality of groups of snap-fit ​​blocks 1011, and the snap-fit ​​blocks 1011 are protruded from the inner wall of the assembly groove 101 toward the outer side of the side wall of the hinge base 5. The design of the snap-fit ​​blocks 1011 can ensure that the connection between the hinge base 5 and the mounting piece is more secure, reduce looseness caused by vibration or external force during use, and effectively prevent the hinge base 5 from accidentally falling off during use, thereby improving the stability of the overall structure. Secondly, the snap-fit ​​blocks 1011 make the assembly of the mounting piece and the hinge base 5 simple and quick, without the need for complicated alignment operations, thereby improving the installation efficiency.

[0038] In terms of the protruding distance of the snap-in block 1011, the distance between the snap-in block 1011 and the inner wall of the assembly groove 101 is L1, and the wall thickness of the side wall of the assembly groove 101 is L2, L1 / L2=40%~50%. Through the design of the snap-in block 1011, the force distribution is optimized to ensure that during the assembly process, the force can be evenly distributed on the side wall of the assembly groove 101, thereby improving the durability and reliability of the hinge and enhancing the stability and anti-falling ability of the assembly between the mounting part and the hinge base 5.

[0039] During design and production, a unified small-bend hinge design is adopted, but in actual use, there are medium-bend and large-bend arm types. Therefore, the mounting parts need to have two specifications. In order to facilitate the standardized production of mounting parts and reduce the difficulty of inventory, the mounting parts are spliced ​​and assembled. That is, the small-bend hinge is padded with one mounting part to form a medium-bend hinge, and two mounting parts are padded to form a large-bend hinge. In order to facilitate the installation and connection between the two groups of mounting parts, the bottom wall of the main body 1 has a raised assembly edge 103, and the outer side wall of the assembly edge 103 is adapted to the inner side wall of the assembly groove 101. By assembling the outer side wall of the assembly edge 103 and the inner side wall of the assembly groove 101, When the two groups of mounting parts are assembled, the assembly groove 101 of the upper group is snap-fitted and assembled with the base 5 of the hinge, and the assembly edge 103 of the upper group is snap-fitted and assembled with the assembly groove 101 of the lower group, thereby completing the assembly between the two groups of mounting parts. By standardizing the production of one type of mounting parts, the production line is simplified, thereby improving production efficiency, reducing inventory costs and the complexity of inventory management. Secondly, the splicing and assembly design of the mounting parts makes the installation process simpler, reduces installation time and labor intensity, and improves the efficiency of installers. Furthermore, through the splicing and assembly of the mounting parts, the conversion from small bend to medium bend and then to large bend is realized, which enhances the compatibility and applicability of the product and meets the needs of more customers.

[0040] Since the mounting piece and the hinge base 5 are assembled by snap-fitting, and the two groups of mounting pieces are assembled by snap-fitting, in order to facilitate the disassembly of the mounting piece, the main body 1 is provided with a disassembly groove 104, and the disassembly groove 104 is recessed from the outside toward the side wall of the assembly groove 101. By providing the disassembly groove 104, the installer can separate the mounting piece and the hinge base 5, or separate the two groups of mounting pieces, by prying the disassembly groove 104, thereby improving the convenience of disassembly and assembly of the mounting piece.

[0041] In terms of the specific structural arrangement of the disassembly groove 104 , the disassembly groove 104 is arranged to extend longitudinally along the body 1 , and two groups of notches are formed on the opposite side walls of the assembly groove 101 , which facilitate the installation personnel to disassemble and assemble the installation parts.

[0042] In order to design the mounting parts to be lightweight, while ensuring the structural rigidity of the mounting parts, reducing the use of mounting material, thereby reducing manufacturing costs, the main body 1 is provided with a plurality of connecting holes 105, the connecting holes 105 are recessed downward from the bottom wall of the self-assembly groove 101, the connecting holes 105 are staggered with the mounting holes 102, and the connecting holes 105 are staggered with the mounting holes 102 to ensure the stability of the fixing screw assembly, the connecting holes 105, and at the same time ensure the structural rigidity of the mounting parts to avoid the structural rigidity of the mounting parts being reduced due to excessive opening area.

[0043] Among them, the main body 1 is provided with multiple groups of connecting holes 105, the cross-sectional area of ​​the connecting holes 105 is S1, the area of ​​the bottom wall of the assembly groove 101 is S2, S1 / S2=2.5%~6.5%, the total area of ​​the multiple groups of connecting holes 105 is S3, S3 / S2=60%~65%, preferably, S3 / S2=62%, the multiple groups of connecting holes 105 are located on the periphery of the mounting hole 102 to form a mounting ring, the mounting hole 102 is located in the mounting ring, and the side walls of the connected connecting holes 105 form a connecting strip. Specifically, the main body 1 is provided with fourteen groups of flow holes, and the connecting strips act as reinforcing ribs to ensure the structural rigidity of the installation. There are three groups of connecting strips arranged horizontally and three groups arranged vertically.
