Description

Technical Field

[0001] The present invention relates to the technical field of furniture, and specifically to a furniture base and a furniture hinge thereof. Background Art

[0002] Chinese Patent Document No. CN213115913U discloses a simple disassembly and assembly mechanism for a furniture hinge and a base on May 4, 2021. It includes a hinge assembly and a fixed base. The hinge assembly at least includes a connecting arm and an intermediate member. An eccentric member is provided between the connecting arm and the intermediate member. Connecting arm flanges are bent on both the left and right sides of the connecting arm, and limiting flanges and buckling flanges are bent on both the left and right sides of the intermediate member; the intermediate member is slidably positioned on the connecting arm flange of the connecting arm through the cooperation of the eccentric member and the limiting flange to achieve an adjustable positioning connection between the connecting arm and the intermediate member; an assembly groove and a buckling member are provided on the fixed base, a side wing is provided on the connecting arm or the intermediate member, and the side wing is slidably positioned on the assembly groove through translation to achieve left-right and / or up-down positioning between the hinge assembly and the fixed base. The buckling member is movably provided on the fixed base and buckles with the buckling flange after the hinge assembly is slid, so as to achieve the mating connection between the hinge assembly and the fixed base. When assembling the hinge assembly of the above structure, it needs to be slid from one end of the fixed base to the other end and assembled in the assembly groove. Its sliding position is relatively long, resulting in the need for more positions during the assembly of the hinge assembly, which is not conducive to the user's assembly of the hinge assembly. At the same time, the hinge assembly can only be disassembled by swinging the buckling member, and it is relatively difficult to apply the swinging force, which is not convenient for the user to disassemble the hinge assembly. Moreover, since the buckling member is swingably arranged, its buckling force is relatively poor, resulting in unstable assembly of the hinge assembly and easy loosening problems. Therefore, it is necessary to further improve. Summary of the Invention

[0011] When the pressing member and the buckling member elastically slide linearly, the pressing limiting portion limits downward on the upper limiting portion, and the buckling limiting portion limits upward on the lower limiting portion, so as to realize the up-and-down limiting type elastic linear sliding of the pressing member and the buckling member on the extension portion.

[0012] A fixing plate is further arranged below the connecting plate, the fixing plate is positioned below the connecting plate, and an up-and-down adjusting member is arranged between the two.

[0024] A front and rear adjustment member is also provided between the middle member and the connecting arm, and the front and rear positioning adjustment of the two is achieved through the front and rear adjustment member.

[0025] The present invention has the following advantages compared with the prior art through the improvement of the above structure:

[0026] 1. By utilizing the fastening effect of the fastener, the pressing member and the buckling member are fixed together, which not only improves the assembly stability of the two, but also utilizes the elastic force of the elastic member to enable the pressing member and the buckling member to elastically linearly slide on the extension part simultaneously. Since the pressing member and the buckling member are fixed together, no matter how large the elastic force of the elastic member is, the separation of the pressing member and the buckling member will not occur. On the basis of ensuring the stable assembly of the two, it is ensured that the elastic member can generate a sufficiently large elastic force, so that a stable assembly can be achieved between the furniture base and the furniture hinge, avoiding loosening problems.

[0027] 2. The pressing member and the buckling member can achieve fixed assembly in the left - right, up - down and front - back positions, further improving the assembly stability of the two and also enhancing the connection compactness between them; the pressing member and the buckling member can simultaneously perform limit sliding in the left - right and front - back positions relative to the connecting plate, thereby reducing the shaking and swinging problems that occur when the pressing member and the buckling member slide, so as to improve the use stability of the pressing member and the buckling member.

[0028] 3. When in use, the user can pre - assemble the fixed base and the furniture hinge on the furniture cabinet body and the furniture door body respectively.

[0029] When the furniture hinge is assembled, the rear assembly part is pre - positioned and guided to be placed on the assembly mating notch through the assembly guiding part, and the front assembly mating part can also be pre - positioned and guided to be placed on the assembly notch through the assembly guiding part. Then the furniture hinge is linearly slid and assembled on the front and rear assembly mating parts by using the front and rear assembly parts respectively. Subsequently, the buckling part and the buckling mating part are mutually guided and buckled through the buckling guiding part, and the left - right, up - down and front - back all - around fixed connection between the furniture hinge and the fixed base can be realized, so as to finally realize the quick disassembly and assembly between the furniture cabinet body and the furniture door body, making the disassembly and assembly between them more convenient and fast, and more stable and firm after assembly.

[0030] Since the front assembly part and the rear assembly mating part can be pre - positioned and guided to be placed on the assembly mating notch and the assembly notch respectively, it is not only convenient for the user to pre - position and place the furniture hinge on the fixed base, avoiding the user having to perform multiple alignments to make the furniture hinge and the fixed base in the correct assembly position, reducing the user's redundant operations and improving the assembly convenience of the user. At the same time, it can also effectively reduce the translational sliding assembly distance between the furniture hinge and the fixed base, enabling the user to assemble the furniture hinge on the fixed base within a limited space position, so that the user can set multiple furniture hinges on the furniture door body, and multiple furniture hinges can be assembled on the fixed base asynchronously, improving the assembly convenience of the user.

[0031] At the same time, guided snap-fitting can be achieved between the snap-fitting portion and the snap-fitting mating portion, so that the user can achieve snap-fitting between the snap-fitting portion and the snap-fitting mating portion by applying less linear sliding force, further improving the user's assembly convenience.

[0032] When the furniture hinge is being disassembled, it is only necessary to use a tool or manual force on the pressing part to separate the buckle part from the buckle fitting part, and then linearly slide the front and rear assembly parts away from the front and rear assembly fitting parts, respectively, to achieve the disassembly between the furniture hinge and the fixed base. During the whole process, when the front assembly part slides to a certain position, it will limit the position on the rear assembly fitting part, which not only prompts the user that the furniture hinge has been disassembled, but also prevents the furniture hinge from sliding too far away, causing the user to be injured or the furniture door body falling from the user's hand, thereby improving the user's safety.

[0033] Moreover, the pressing of the pressing part is a downward linear operation, and its operation process is convenient and quick. Compared with the swinging or rotating of the prior art (in addition to applying a pressing force, the user also needs to apply a swinging or rotating force), the user only needs to apply a single pressing force, which is easier to apply.

[0034] 4. Due to the positioning and matching relationship between the front assembly part and the front assembly matching part, between the rear assembly part and the rear assembly matching part, and between the buckling parts and the buckling parts, the furniture hinge will not be separated from the fixed base when subjected to forces in different directions after assembly, so that the structural strength of the furniture hinge is higher and the load-bearing capacity is stronger. It not only avoids the safety hazards such as breakage and deformation during use, which may cause the furniture door to fall, but also further improves the assembly stability between the fixed base and the furniture hinge, making the service life of the furniture hinge longer. At the same time, it can also be widely used on furniture doors with larger volume and weight.

[0035] 5. The pressing piece and the buckle piece can slide linearly elastically on the extension part, and their direction is different from the direction of sliding and disassembling of the furniture hinge. Not only can the buckle fitting part generate a reaction force in a different direction compared to the removal of the furniture hinge after the furniture hinge and the fixed base are assembled, so that the furniture hinge can be firmly assembled on the fixed base, but it can also facilitate users to apply a linear pressing force to the pressing piece and the buckle piece, thereby improving the convenience of removing the furniture hinge and the fixed base.

[0036] In general, it has the characteristics of reasonable structure, compact connection between components, low manufacturing cost, easy production, easy implementation, wide range of use, fast, simple and convenient disassembly and assembly process, and firm assembly, and is highly practical.
