[0029] The mounting seat 2 is provided with an inner recessed driving groove 21, the height adjusting eccentric pin 6 is mounted in the driving groove 21, and the bottom of the driving groove 21 is provided with an extrusion hole 22, and the eccentric shaft at the bottom of the height adjusting eccentric pin 6 penetrates through the extrusion hole 22 and is hinged with the driving seat 3.

[0030] The angle adjusting device is a screw hole 23 arranged on the mounting seat 2, the guide pin 61 is screwed in the screw hole 23, rotating the guide pin 61 drives the driving seat 3 to swing relative to the base 4, and the relative angle between the driving seat 3 and the base 4 is adjusted.

[0031] The left-right adjusting device comprises a plurality of transverse guide grooves 7 arranged on the base 4, a transverse rivet 71 penetrates through the transverse guide groove 7 and is riveted with the movable seat 5, and can slide along the transverse guide groove 7; further comprising a transverse adjusting eccentric pin 72 movably hinged on the base 4, the movable seat 5 is provided with a transverse adjusting driving groove 73, the transverse adjusting eccentric pin 72 partially extends into the transverse adjusting driving groove 73, and the movable seat 5 is pushed to slide transversely relative to the base 4 by rotating the transverse adjusting eccentric pin 72 and extruding the transverse adjusting driving groove 73.

[0032] The base 4 further protrudes a plurality of clamping tables 41 towards the movable seat 5, correspondingly, the movable seat 5 is provided with a movable groove 51, and the clamping table 41 extends into the movable groove 51 and slides.

[0034] Working principle: in the case, a containing cavity is arranged in the mounting seat of the hinge, and a driving seat is mounted in the containing cavity, a height adjusting device and an angle adjusting device are arranged between the driving seat and the base fixedly mounted on the cabinet door, and the relative height and the inclination angle between the cabinet door and the cabinet body are adjusted. Meanwhile, a left-right adjusting device is arranged between the base and the movable seat, and the position of the cabinet door in the left-right direction is adjusted.

[0035] Specifically, the height adjusting device is a height adjusting eccentric pin rotatably mounted on the mounting base and riveted with the driving base. In order to guide the height adjustment, the guide pin on the mounting base is slidingly buckled in the height guide groove of the driving base. When the user rotates the height adjusting eccentric pin, the driving base is slidingly adjusted along the height guide groove. Due to the eccentricity of the eccentric pin, the rotation of the eccentric pin causes the driving base to move up and down along the height guide groove, thereby adjusting the height difference between the driving base and the base and further adjusting the height of the cabinet door. The sliding buckling connection of the guide groove increases the stability during adjustment, so that the height adjustment is not easy to change after adjustment, effectively increasing the service life and stability.

[0036] In the angle adjusting device, the guide pin is screwed in the screw hole on the mounting base. When the guide pin is rotated, the relative height between the guide pin and the mounting base changes, driving the driving base to swing on the base by a certain angle, thereby adjusting the relative angle between the hinge and the cabinet, and adjusting the inclination angle of the cabinet door. Precise control of the angle between the cabinet door and the cabinet makes the cabinet door more closely fit the cabinet in the closed state, which is beneficial to the airtightness of the cabinet door after installation.

[0037] In the left-right adjusting device, a plurality of transverse guide grooves are provided on the base, and a transverse rivet is used to rivet the movable seat through the transverse guide groove. Meanwhile, a transverse adjusting drive groove is also provided on the movable seat, and a transverse adjusting eccentric pin is partially inserted into the transverse adjusting drive groove. Rotating the transverse adjusting eccentric pin, the movable seat is adjusted in the left-right direction by the eccentric pin characteristics, generating a transverse extrusion thrust on the movable seat, so that the movable seat slides relative to the base, and finally the left-right displacement of the cabinet door is adjusted. The compact structure design can complete the left-right displacement adjustment through simple rotation operation, which is convenient and precise. The sliding is smooth during adjustment, and loosening is avoided, further improving the installation effect between the cabinet door and the cabinet.

[0038] In order to facilitate the user to install and disassemble the cabinet door, a front connecting shaft and a rear elastic buckle are arranged in the driving base, a quick release groove is arranged on the end face of the movable seat, the quick release groove is inserted into the front connecting shaft of the front cover and connected with the front connecting shaft, and the rear elastic buckle is buckled and fixed on the buckle plate on the end face of the movable seat to quickly install and connect the hinge. Similarly, when the cabinet door needs to be disassembled, the rear elastic buckle is separated from the buckle plate by pressing the rear elastic buckle, so that the movable seat is disconnected, the convenience of maintenance and installation of the hinge is improved, the installation and disassembly process of the cabinet door is faster and more convenient, the time and operation cost of the user are saved, and therefore the cabinet door can be widely used.

[0039] The basic principle and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
