All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0017] See Figures 1 to 7As shown in the figure, a cabinet door hinge structure includes a hinge seat 2 fixed to the door panel 1 by screws and a side plate base 4 fixed to the side plate 3 of the cabinet body. In this embodiment, the above structures are all conventional structures of the prior art and are only simply applied, so they are not described in detail. In this embodiment, an adjustment seat structure 5 is provided on the side plate base, and an adjustment damping structure 6 and a hinge bracket 7 are provided on the adjustment seat structure. Moreover, the end of the hinge bracket is rotatably connected to a dial 9 through a support shaft 8, and a connection block 10 and a U-shaped connection shaft 11 are provided on the hinge seat. During assembly, the U-shaped connection shaft penetrates through the side wall of the hinge seat and is rotatably connected to the dial and the connection block at both ends respectively. That is, the U-shaped connection shaft is used to connect the hinge seat, the dial and the connection block, which can not only realize the connection of the three but also ensure the rotation effectiveness of the dial and the connection block. In actual application, the U-shaped connection shaft can be replaced with other conventional shaft parts for use.

[0018] Furthermore, the end of the adjustment damping structure is rotatably connected to the support shaft. At the same time, a transmission piece 12 is provided between the connection block and the hinge bracket. One end of the transmission piece is rotatably connected to the hinge bracket through a shaft rod 13, and the other end is attached to the connection block and connected to the U-shaped connection shaft. Through the above structure, when the dial and the connection block rotate relative to each other to open or close, it will drive the transmission piece to move synchronously, ensuring the effectiveness and stability of opening or closing. In this embodiment, there is a groove in the middle of the bottom surface of the transmission piece, and the connection part of the dial and the connection block is located in the groove.

[0019] In addition, a torsion spring 14 is sleeved on the shaft rod, and a positioning shaft 15 is provided on the dial. The positioning shaft is above the support shaft, and the end rods of the torsion spring are respectively positioned on the bottom surface of the hinge bracket and the positioning shaft. Through the above structure, the torsion effectiveness can be ensured by the torsion spring. During use, the hinge opening and closing damping buffering are realized through the torsion spring and the damper.

[0020] In this embodiment, the adjustment seat structure 5 includes an adjustment support seat 51 and an adjustment bracket 52 provided on the adjustment support seat. A strip-shaped groove 16 is provided on the side plate base, and a positioning pin 17 is provided on the adjustment support seat, and the positioning pin is located in the strip-shaped groove. In this embodiment, the provision of the strip-shaped groove in cooperation with the positioning pin can realize the position adjustment of the whole adjustment seat structure on the side plate base, and cooperate with the subsequent adjustment through groove to improve the adjustment range and realize three-dimensional adjustment operation.

[0021] An adjustment slot 18 is provided on the adjustment bracket, and a screw 19 is provided on the adjustment support base. The screw passes through the adjustment slot. The adjustment bracket is adjusted on the adjustment support base and locked by the screw. One end of the hinge bracket away from the support shaft is connected to the adjustment bracket through a movable shaft body 20. The adjustment slot includes a left-right adjustment slot for adjusting the left-right direction and a front-back adjustment slot for adjusting the front-back direction. With the above structure, it can not only achieve left-right adjustment but also front-back adjustment, thus meeting its adjustment requirements in different directions. Moreover, the adjustment bracket can not only be positioned by the screw but also be adjusted on the adjustment support base, so as to meet the usage requirements in different situations and improve its application range. In the above structure, the length and width of the strip slot and the adjustment slot can be processed and set according to needs to meet the usage requirements.

[0022] Moreover, the adjustment damping structure includes a C-shaped adjustment seat 61, a damping fixed seat 62, a damper 63, a buffer spring 64, and a damping adjustment member 65. During assembly, the C-shaped adjustment seat is located on the top surface of the adjustment bracket, and translation slots 66 are provided on the symmetric side edges of the C-shaped adjustment seat. Translation strip protrusions 67 that cooperate with the translation slots are provided on the symmetric side surfaces of the damping fixed seat. The depth of the recessed area of the C-shaped adjustment seat matches the height of the damper. In this embodiment, the damper is a conventional structure of the prior art and is simply applied, mainly for the effect of damping and buffering. The length of the translation slot can be processed and set according to needs. During assembly, the damping fixed seat is located inside the C-shaped adjustment seat, and the translation strip protrusion can be translated in the translation slot. The support shaft is connected to the bottom surface of the end of the damping fixed seat. The damper is located inside the C-shaped adjustment seat and one end is connected to the damping fixed seat through the damping adjustment member. The buffer spring is arranged between the damper and the inner wall of the recessed area of the C-shaped adjustment seat. By providing the buffer spring, it is beneficial to effectively buffer the damper, reduce the pressure on the damper, and improve the service life of the damper. Moreover, the translation slot and the translation strip protrusion are provided to ensure the convenience and effectiveness of damper adjustment, effectively solving the problem of too slow damping caused by the excessive weight of the door and meeting the selection of buffering at 20 degrees - 40 degrees.

[0023] At the same time, a bushing 21 is sleeved on the abutting shaft. The end rod of the torsion spring abuts on the bushing. The additional bushing can solve the problems of unsmoothness and abnormal noise generated when the torsion spring twists, and improve the service life.

[0024] Moreover, an installation positioning member 22 is provided at one end of the adjustment bracket close to the hinge seat. The installation positioning member is mainly used for positioning during installation to ensure the accuracy of the installation position, improve the installation accuracy, and ensure the reliability of the installation.
