[0022] The hinge is connected to the door frame by screws, and the screw holes on the hinge seat usually need to be decorated with a panel to hide them. The traditional cover plate is connected to the hinge seat with bolts, which has a poor decorative effect and is inconvenient to load and unload, making it inconvenient to use.

[0023] For this purpose, refer to Figure 1 and Figure 2, which is a door hinge proposed by the utility model, includes a sealing plate 300 and a first mounting seat 100 and a second mounting seat 200 respectively mounted on the door frame and the door leaf, the first mounting seat 100 is rotatably connected to a single-tooth hinge 400, the second mounting seat 200 is rotatably connected to a double-tooth hinge 500, and the single-tooth hinge 400 and the double-tooth hinge 500 are hinged to each other. There are multiple sealing plates 300, which are covered on the surfaces of the first mounting seat 100 and the second mounting seat 200. The first mounting seat 100 and the second mounting seat 200 are both provided with a penetrating mounting hole 110 for passing fasteners for fixing to the door frame or the door leaf. The first mounting seat 100 and the second mounting seat 200 are both provided with an adsorption groove 120, and the adsorption groove 120 is embedded with a magnetic suction component 130. The magnetic suction component 130 can adsorb and fix the sealing plate 300, so that the sealing plate 300 covers the outer side of the mounting hole 110, so that the surface of the first mounting seat 100 and the second mounting seat 200 is a smooth surface. It is understandable that by slotting the door frame and the door leaf, the first mounting seat 100 and the second mounting seat 200 are fixed in the slots through fasteners provided in the mounting frame, so that they are hidden in the door leaf and the door frame, and the first mounting seat 100 and the second mounting seat 200 are embedded with single-tooth hinges 400 and double-tooth hinges 500 that are hinged to each other, so that the first mounting seat 100 and the second mounting seat 200 can rotate relative to each other, thereby realizing the opening and closing of the door leaf. The sealing plate 300 is directly adsorbed on the surface of the first mounting seat 100 and the second mounting seat 200 through the magnetic suction member 130, and the fasteners and mounting holes 110 exposed on the surface are covered and blocked, so that the overall surface of the first mounting seat 100 and the second mounting seat 200 is flat and consistent. When disassembly is required, it can be directly removed manually, without the need to simultaneously twist the fasteners to disassemble the sealing plate 300, resulting in the need to re-fix and install the entire hinge, thereby optimizing the use.

[0024] Reference Figure 1 , is an embodiment of the present invention, wherein a total of four sealing plates 300 are provided, of which two sealing plates 300 are provided on both sides of the single-tooth hinge 400 of the first mounting seat 100, and the other two sealing plates 300 are provided on both sides of the double-tooth hinge 500 of the second mounting seat 200, so as to adapt to the structure of the hidden hinge. In addition, the first mounting seat 100 and the second mounting seat 200 are respectively provided with at least four adsorption grooves 120, and each sealing plate 300 is fixed by adsorption through two adsorption grooves 120, thereby improving the stability of the fixing of the sealing plate 300 and preventing the sealing plate 300 from falling off.

[0025] Reference Figure 2The first mounting seat 100 is provided with an up-down adjustment block 410 and a left-right adjustment block 420, and the second mounting seat 200 is provided with a front-back adjustment block 510, wherein the up-down adjustment block 410 is connected to the left-right adjustment block 420, and the left-right adjustment block 420 and the front-back adjustment block 510 are connected through a single-tooth hinge 400 and a double-tooth hinge 500. Further, the movable end of the single-tooth hinge 400 is hinged to the left-right adjustment block 420, and the movable end of the double-tooth hinge 500 is hinged to the front-back adjustment block 510. Further, the upper and lower adjustment blocks 410 are provided with a concave platform 413 and a strip-shaped long hole 411, the concave platform 413 is provided with a fixing hole 412, the left and right adjustment blocks 420 are correspondingly provided with a boss 421 placed on the concave platform 413, and the boss 421 is transversely provided with a wide hole 422 corresponding to the fixing hole 412, the upper and lower adjustment blocks 410 are fixed to the first mounting seat 100 by passing the fixing bolts through the long hole 411, and the left and right adjustment blocks 420 are fixed to the upper and lower adjustment blocks 410 by passing the fixing bolts through the wide hole 422 and threadedly connected to the fixing hole 412. It should be noted that the front and rear adjustment blocks 510 are provided with adjustment screw holes 511, and the adjustment screw holes 511 are threadedly connected with adjustment bolts for fixing the front and rear adjustment blocks 510 to the second mounting seat 200.

[0026] The mounting seat is conveniently adjusted by independent adjustment components, maintaining the integral structural strength of the mounting seat, while effectively avoiding the stress defects of the integral design of the adjustment components, and reducing the number of components connecting the hinges, which is convenient for production and processing, reduces costs, and improves overall strength and firmness. During installation, the first mounting seat 100 and the second mounting seat 200 are respectively installed on the door frame and the door leaf, so that the door leaf can be opened and closed through the hinge. When installing the door leaf, it is generally impossible to accurately match the door frame. Therefore, the position adjustment can be achieved through the front and rear adjustment blocks 510, the upper and lower adjustment blocks 410 or the left and right adjustment blocks 420. By replacing multiple hinged components with single-tooth hinges 400 and double-tooth hinges 500, the structure is reliable and the cost can be effectively reduced.

[0027] Reference Figure 2 The front and rear adjustment blocks 510 and the left and right adjustment blocks 420 are provided with a first slide groove 512 and a second slide groove 423, the movable end of the double-tooth hinge 500 is provided with a first slider 513 matching the first slide groove 512, and the movable end of the single-tooth hinge 400 is provided with a second slider 424 matching the second slide groove 423. When the door leaf is opened and closed, the single-tooth hinge 400 and the double-tooth hinge 500 rotate around the axis of the middle hinge, the first mounting seat 100 and the second mounting seat 200 rotate around the rotating ends of the single-tooth hinge 400 and the double-tooth hinge 500 respectively, and the movable ends of the two hinges move through the cooperation and guidance of the first slider 513, the second slider 424 and the first slide groove 512, the second slide groove 423, thereby guiding the opening and closing direction of the door leaf.

[0028] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
