Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Referring to fig. 1 to 9, in an embodiment of the present invention, an embedded hinge of an eccentric shaft gear mechanism includes a rotating mounting plate 1 and a mounting block 5, an outer gear ring 2 and an inner gear 4 are respectively fixedly mounted between the mounting plate 1 and the mounting block 5, the inner gear 4 is sleeved on an inner ring of the outer gear ring 2, an eccentric shaft 3 for keeping one side of the inner gear 4 engaged with an inner side of the outer gear ring 2 is mounted between the outer gear ring 2 and the inner gear 4, and two eccentric shafts of the eccentric shaft 3 are respectively rotatably mounted at circle center positions of the outer gear ring 2 and the inner gear 4;

during operation, the outer ring gear 2 and the inner tooth 4 that set up are installed between mounting panel 1 and mounting block 5, outer ring gear 2 can be installed on mounting panel 1, inner tooth 4 is installed on mounting block 5, or exchange each other, namely inner tooth 4 is installed on mounting panel 1, outer ring gear 2 is installed on mounting block 5, as long as guarantee restraint regulation is all available, wherein mounting panel 1 is installed on the front panel of cabinet body articulated department under the general condition, mounting block 5 is embedded to be installed on the door body that needs the upset, thereby mounting panel 1 and mounting block 5's rotation connection realize the door body and rotate the functional requirement on the cabinet body, when mounting block 5 rotates, inner tooth 4 can be through the tight meshing rotation of the inner ring wall of outer ring gear 2 of spacing of eccentric shaft 3, thereby the motion trail of the articulated limit of the door body and the motion trail of the rotation junction of eccentric shaft 3 and inner tooth 4 directly relate to each other, in the angle opening and closing process of door body on a large scale, the centre of circle department of inner tooth 4 has only made the circle department around the centre of outer ring gear 2 and has made the circular rotation, therefore, the door body's limit is in the opening and closing process, the door body's limit is in the outside environment that the door body's articulated limit has also reduced the external ring gear and the installation block's use gap, especially the installation gap of the external door body and the external door body's environment is suitable for the external use the external clearance, the external door body's environment.

The eccentric shaft 3 comprises a central block 30, an upper shaft 31 and a lower shaft 32, the upper shaft 31 and the lower shaft 32 are respectively and vertically fixed on the top surface and the bottom surface of the central block 30, and the axial lines of the upper shaft 31 and the lower shaft 32 are staggered;

the outer toothed ring 2 is fixed on a panel of the mounting plate 1, the inner teeth 4 are fixed on a panel of the mounting block 5, the inner teeth 4 are embedded in an inner ring of the outer toothed ring 2, the upper shaft 31 is rotatably mounted at the circle center position of the inner teeth 4, and the lower shaft 32 is rotatably mounted on the panel of the mounting plate 1 at the circle center position of the outer toothed ring 2;

when the door is in operation, when the mounting plate 1 is fixedly mounted, the outer gear ring 2 and the mounting plate 1 are kept stationary, and when the mounting block 5 is mounted on a rotating door body, the mounting block 5 drives the inner teeth 4 to rotate in inner engagement with the outer gear ring 2.

The radius of a reference circle of the outer gear ring 2 is A, the radius of a reference circle of the inner gear 4 is B, and the eccentric wheelbase of the gear 3 is C, so that A = B + C;

in operation, as shown in fig. 9, it is necessary to ensure that the internal teeth 4 can always rotate in the external gear ring 2 by meshing, and it is necessary to ensure that the reference circle of the internal teeth 4 is always inscribed in the reference circle of the external gear ring 2, and at this time, the connection between the internal teeth 4 and the external gear ring 2 is limited by the eccentric shaft 3, so that the length of the eccentric axis distance of the eccentric shaft 3 and the radius of the reference circle of the internal teeth 4 is exactly equal to the length of the radius of the reference circle of the external gear ring 2, i.e., a = B + C.

Example 2

Referring to fig. 10, the difference between the present embodiment and embodiment 1 is:

the outer gear ring 2 is fixed on a panel of the mounting block 5, the inner teeth 4 are fixed on the panel of the mounting block 1, the outer gear ring 2 covers the outer ring of the inner teeth 4, the lower shaft 32 of the eccentric shaft 3 is rotatably mounted at the circle center position of the inner teeth 4, and the upper shaft 31 is rotatably mounted on the panel of the mounting block 5 at the circle center position of the outer gear ring 2;

when the door is in operation, when the mounting plate 1 is fixedly mounted, the inner teeth 4 and the mounting plate 1 are kept fixed, and when the mounting block 5 is mounted on a rotating door body, the mounting block 5 drives the outer gear ring 2 to rotate in a meshed manner on the outer ring of the inner teeth 4.
