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 fast detachable concealed hinge, which belongs to the technical field of hinges and solves the existing technical problems such as complex structure of the hinge, difficult disassembly and assembly of the anti-off device, small opening and closing angle of the movable door, and large door gap. The hinge includes a moving vane and a stationary vane, the stationary vane is in the shape of a groove and includes first to third groove surfaces, the second groove surface and the third groove surface both include a hollow part in the middle, and the hollow part can accommodate the moving blade. blade; both ends of the third groove surface are provided with a first rotating shaft hole and a second rotating shaft hole; the moving blade is provided with a moving shaft hole, and the moving blade and the stationary blade pass through the rotating shaft, the first rotating shaft hole, the moving rotating shaft hole and the second rotating shaft The hole is hinged; the first groove surface is detachably connected to the door frame; and the movable blade is fixedly connected to the movable door. The hinge can be used for left-handed and right-handed doors, the door opening angle is greater than 140°, and the door gap is less than 2.5mm. It has good rainproof, salt spray, mold, and corrosion performance, as well as strong bearing capacity, small size, and light weight. .
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...
