detailed description

The present invention will be specifically and further described below in conjunction with the accompanying drawings. An improved structure of a cabinet door hinge, which includes a hinge cup 2 and a hinge arm 3 hingedly installed by a triangular arm 1. A buffer device is arranged in the hinge arm 3 to be hinged with the triangular arm. An eccentric shell 4 is arranged in the hinge arm 3. The eccentric The shell 4 is detachably installed on the base 5, the hinge cup 2 is connected with the cabinet body, and the base 5 is connected with the cabinet door. It is characterized in that an eccentric adjustment device 6 is arranged between the hinge arm 3 and the eccentric shell 4, the The eccentric adjusting device 6 includes an eccentric disc 61 and a central shaft 62 arranged on its upper end surface. The central shaft 62 is rotatably installed in the adjustment hole 31 of the hinge arm 3 . The drive shaft 63 extends into the drive groove 41 provided in the eccentric casing 4, and the lower end surface of the eccentric disc 61 is also provided with an eccentric groove 7, and correspondingly, an eccentric column 8 is provided on the eccentric casing 4 to extend into the eccentric groove 7, when the user rotates the central shaft 62, the eccentric housing 4 can be driven to slide back and forth in the hinge arm 3 through the eccentric disk 61, so as to control the relative distance between the base 5 and the hinge arm 3.

The central shaft 62 is provided with a knife groove 64 which can be matched with a screwdriver. The guide groove can be set in a "ten" shape, a "one" shape, or even a hexagonal shape or other shapes that can be driven by tools to rotate, which is not specifically limited.

The eccentric groove 7 includes a first eccentric groove 71 and a second eccentric groove 72 arranged on the eccentric disc 61, and the centers of the two eccentric grooves are not coincident.

The groove depths of the first eccentric groove 71 and the second eccentric groove 72 are not on the same plane, and are arranged in a vertically offset manner. Since some tracks of the first eccentric groove and the second eccentric groove overlap, in this case, the groove depth of the eccentric groove is misplaced.

The eccentric column 8 includes a first eccentric column 81 and a second eccentric column 82 arranged on the eccentric housing 4 , extending into the first eccentric groove 71 and the second eccentric groove 72 respectively.

The driving groove 41 is a waist groove.

Working principle: After the cabinet door, cabinet body, hinge cup and base are installed, and it is found that the relative distance between the hinge arm and the base needs to be adjusted, the user only needs to use tools to drive the central shaft 62 to rotate, thereby driving the eccentric disc 61 to rotate. When the eccentric disk rotates, the eccentric column 8 on the eccentric casing will slide in the eccentric groove on the eccentric disk. Since the center of the eccentric groove does not coincide with the axis of the central shaft, when the eccentric disc rotates, the eccentric shell can be driven by the eccentric column to slide back and forth in the hinge arm, thereby realizing the function of adjusting the relative distance between the cabinet door and the cabinet body.

What needs to be explained is: due to the setting of the eccentric groove and eccentric column in this case, the eccentric column can slide more smoothly in the eccentric groove, so it can make the user's adjustment more convenient and quick. During use, there is a certain impact force between the hinge arm and the eccentric housing, and the setting of the double eccentric grooves can make the stress points of the first eccentric column and the second eccentric column be located on both sides of the central axis 62 and at the same time the forces cancel each other out , so that the eccentric column cannot push the eccentric disk to rotate, and has a good self-locking ability. Thereby avoiding the reverse rotation of the eccentric nail in the traditional technology when the force is applied, resulting in displacement between the hinge arm and the eccentric shell, causing the cabinet door to deviate, so it can be widely used.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above. Those skilled in the industry should understand that the present invention is not limited by the above-mentioned embodiments. What are described in the above-mentioned embodiments and the description only illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will also have Various changes and improvements, such as the setting of the eccentric groove, the structure of the eccentric column, etc., all of these changes and improvements fall within the scope of the claimed invention.
