Problems solved by technology
Whether the door or window using this hinge is open or closed, the hinge is exposed, which not only takes up space, but also affects the flatness and appearance. Now there is a hidden hinge that can be completely hidden in the door and door frame when the door is closed. Inside or inside windows and window frames, however, this kind of hinge cannot be closed automatically after opening the door or window, which is inconvenient for people to use

Embodiment Construction
[0019] refer to Figure 1 to Figure 4 , the present invention discloses a self-closing concealed hinge, which comprises at least two articulated crank arms 2, a pivot 3 rotatably connected to the crank arms 2, and a hinge body 1 movably connected to the pivot 3. The hinge body 1 is equipped with There is a shifting block 4 pivotally connected with it, and an elastic element 5 is arranged between the shifting block 4 and the hinge body 1. One end of the elastic element 5 is supported on the hinge body 1, and the other end is supported on the shifting block 4. On the shifting block 4 There is provided a first pressing portion 41 capable of interacting with the pivot 3 so that the pivot 3 drives the hinge 1 to close. Further, the shifting block 4 is provided with a second pressing portion 42 capable of interacting with the pivot 3 to keep the two hinges 1 open.
[0020] As shown in the figure, in this example, a transition portion 43 is provided between the first pressing portio...

The invention discloses a self-closing hidden hinge comprising at least two hinged crank arms, pivots and hinging bodies, wherein the pivots are rotatably connected with the crank arms; and the pivots are movably connected with the hinging bodies. Each hinging body is internally provided with a shifting block which is pivoted with the hinging body; a torsional spring is arranged between the shifting block and the hinging body; the elastic force of the torsional spring can cause a first top pressure part to extrude the pivots mutually; and the extruded pivots drive the two hinging bodies which are movably connected with the pivots to fold, thus realizing automatic closing of a door or windows which are fixed with the hinging bodies, helping a user to form a habit of closing the door when going in and out, and avoiding a phenomenon that the door is not closed fully when the user closes the door, thereby saving indoor air conditioning or central heating resource. The self-closing hidden hinge can cause a second top pressure part to extrude the pivots mutually by the elastic force of the torsional spring, and the extruded pivots drive the two hinging bodies which are movably connected with the pivots to open, thus the door or the windows can be in an open state all the time, thereby being convenient to meet guests, carry cargoes, ventilate and the like.
Description
technical field [0001] The invention relates to a hardware product, in particular to a self-closing concealed hinge. Background technique [0002] Doors, windows, etc. are mostly movably connected to corresponding frames through hinges to realize their opening and closing functions. Usual hinge all is to be made of two blades and pin shaft, and a blade is fixed on the side of door or form, and another sheet is fixed on the side of corresponding frame body, and door, window can rotate around pin shaft. Whether the door or window using this hinge is open or closed, the hinge is exposed, which not only takes up space, but also affects the flatness and appearance. Now there is a hidden hinge that can be completely hidden in the door and door frame when the door is closed. Inside or in windows and window frames, but this kind of hinge cannot be closed automatically after opening the door or window, and it is inconvenient for people to use. Contents of the invention [0003] I...
