Embodiment Construction
[0024] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and together with the embodiments of the present invention are used to explain the principle of the present invention and are not intended to limit the scope of the present invention.
[0025] When the door is closed, no part of the hinge can be seen from the outside, which improves the overall aesthetic level of the combination of the door leaf and the door frame. However, this hidden hinge has the disadvantages of complex structure, numerous components, inconvenient manufacture and high cost.
[0026] The invention provides a quick disassembly hidden hinge, such as figure 1 As shown, it includes a moving blade 2, a stationary blade 1 and an anti-off device. The stationary blade 1 is in the shape of a groove and includes a first groove surface 11, a second groove surface 12...

The invention relates to a concealed hinge capable of being quickly disassembled, and belongs to the technical field of hinges. By the aid of the concealed hinge, the technical problems of complicatedstructures of existing hinges, difficulty in disassembling dropping preventive devices, small opening and closing angles of movable doors, large door gaps and the like can be solved. The concealed hinge comprises a movable blade and a stationary blade. The groove-shaped stationary blade comprises a first groove surface, a second groove surface and a third groove surface, hollow portions are arranged in the middle of the second groove surface and the middle of the third groove surface, and the movable blade can be accommodated in the hollow portions; a first rotary shaft hole and a second rotary shaft hole are formed in two ends of the third groove surface; a movable rotary shaft hole is formed in the movable blade, and the movable blade is hinged to the stationary blade by a rotary shaft,the first rotary shaft hole, the movable rotary shaft hole and the second rotary shaft hole; the first groove surface can be detachably connected with door frames; the movable blade can be fixedly connected with movable doors. The concealed hinge has the advantages that the concealed hinge can be used for left opening doors and right opening doors, door opening angles are larger than 140 degrees,and door gaps are smaller than 2.5 mm; the concealed hinge is excellent in rainproof, salt-spray-proof, anti-mildew and anti-corrosion property and high in bearing capacity, and is small and light, and the like.
Description
technical field [0001] The invention relates to the technical field of hinges, in particular to a quick-disassembly hidden hinge. Background technique [0002] At present, the hinge is mainly composed of stationary blades, moving blades and rotating shafts. The stationary blades are fixed to the door frame of the cabinet body, the moving blades are fixed to the movable door, and the rotating shaft is used to connect the stationary blades and the moving blades. To realize the function of the hinge, there are many hinge structures with different installation methods. [0003] In the prior art, some hinges with non-concealed structure, due to the limitation of structural design, the stationary blade and the moving blade are fixed on the outside of the door frame or movable door, which increases the overall size of the cabinet, the hinge structure has no hidden performance, and the appearance effect poor. For some hidden hinges, the anti-off device of the rotating shaft is not...
