Description

Technical Field

[0001] The invention relates to a simple disassembly and assembly mechanism for a furniture hinge and a base. Background Art

[0002] The Chinese patent document number CN2780937Y disclosed a three-dimensionally adjustable furniture door concealed hinge on May 17, 2006, which includes a movable base that can be fixed on the door body, an adjustable base that can be fixed on the door frame, and a rotating arm connected therebetween, wherein the adjustable base includes a bottom plate that can be fixed on the door frame, a middle plate that slides up and down on the bottom plate, and an upper adjustment plate that slides back and forth on the middle plate. That is, the base on the door frame is a three-layer plate structure, wherein the plate is formed by alloy casting and then riveted with the lower adjustment plate by secondary extrusion. Although the hinge production process of the above structure is simple, its adjustable base is fixed to the door frame by screws. When assembling, the user must first connect the door body and the hinge, and then fix the two together on the cabinet body by screws. When disassembling, the entire door body and the hinge can only be disassembled by loosening the screws, which makes it extremely inconvenient to disassemble and assemble, and the user is difficult to disassemble and assemble, and cannot meet the user's use needs. Therefore, it is necessary to make further improvements. Summary of the invention

[0009] The buckled flange is located in front of the limiting flange and is bent on the left and right sides of the middle piece, wherein the bending direction of the buckled flange is the same as or different from the bending direction of the limiting flange, and the left and right outer side dimensions of the buckled flange are smaller than the left and right outer side dimensions of the limiting flange.

[0010] The side wings are bent on the connecting arm flange of the connecting arm, or on the limiting flange of the middle piece; the assembly grooves are arranged on the left and right sides of the fixed base, and the left and right inner dimensions of the assembly grooves are larger than the left and right outer dimensions of the side wings.

[0011] The assembly groove is also provided with a covering portion, and the covering portion covers the outer side of the side wing to achieve left-right and / or up-down positioning between the connecting arm or the middle piece and the fixed base.

[0012] The rear end of the assembly groove is provided with a groove step portion, and the size between the two is equivalent to the size of the front end of the side wing, and the rear end of the side wing is provided with a side wing step portion, and the size between the two is equivalent to the size of the front ends of the left and right assembly grooves, wherein the front end size of the assembly groove is larger than its rear end size and / or the front end size of the side wing, and the front end size of the side wing is smaller than its rear end size; the connecting arm or the middle piece is slidably arranged in the assembly groove through the side wing, the front end of the side wing and the groove step portion are positioned and matched with each other up and down, and the rear end is positioned and matched with the front end of the assembly groove through the side wing step portion.

[0019] The present invention has the following advantages compared with the prior art through the improvement of the above structure:

[0020] 1. A connecting arm flange and a limiting flange are elastically bent on the left and right sides of the connecting arm and the middle piece respectively. The middle piece can achieve elastic interference fit with the connecting arm flange of the connecting arm through the limiting flange, thereby improving the assembly stability between the connecting arm and the middle piece. At the same time, the middle piece can also be slid in the connecting arm U-shaped groove of the connecting arm through the eccentric piece for front and rear positioning. Due to the elastic interference between the connecting arm and the middle piece, the two can only move relative to each other in one direction during adjustment, thereby avoiding the problem of virtual position or adjustment failure between the connecting arm and the middle piece during the adjustment process, so as to improve the adjustment accuracy of the two.

[0021] 2. When in use, the user can pre-assemble the fixed base and the hinge assembly on the furniture cabinet and the furniture door respectively. During assembly, the translational sliding cooperation between the side wing and the assembly groove, the mutual connection between the buckle flange and the buckle piece, and the mutual cooperation between the groove step part and the side wing step part can be used to achieve left-right, front-back, and up-down all-round positioning cooperation between the hinge assembly and the fixed base, so as to finally realize the rapid disassembly and assembly between the furniture cabinet and the furniture door, making the disassembly and assembly between the two faster and more convenient, and more stable and firm after assembly.

[0022] 3. The dimensions of the assembly groove, connecting arm flange, limit flange, buckle flange and side wing are optimized and adjusted to make the mutual assembly more reasonable. The guiding function of the guide part and the positioning function of the groove step part and the side wing step part are combined to further improve the assembly simplicity and stability of the fixed base, connecting arm and middle piece.

[0023] 4. After assembly, the hinge assembly will not fall off the fixed base when subjected to force in different directions, making the structural strength of the furniture hinge higher and the load-bearing capacity stronger. It not only avoids the potential safety hazards of 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 hinge assembly, extending the service life of the furniture hinge. At the same time, it can also be widely used on furniture doors with larger volume and weight.

[0024] 5. The translational sliding device between the hinge assembly and the fixed base can be guided by various guide parts, which is convenient for users to assemble the hinge assembly and the fixed base, thereby improving the user's experience; and, an eccentric piece, and / or left and right, and / or up and down adjustment piece are provided between the hinge assembly and the fixed base. Users can use the eccentric piece, and / or left and right, and / or up and down adjustment piece to adjust the front and back, and / or left and right, and / or up and down position between the hinge assembly and the fixed base according to actual usage needs, thereby making the appearance of the furniture cabinet and the furniture door body after assembly more neat and beautiful, thereby further improving the user's experience.

[0025] 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.
