[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figure 1-8 , a reversely mounted hinge, including a reverse mounting base 1, the reverse mounting base 1 is installed on the outer side of the side plate of the cabinet body, and a rotating arm 11 is movably arranged inside the reverse mounting base 1.

[0030] An adjustment cup 2, the adjustment cup 2 is installed at one end of the rotating arm 11, guide inclined holes 21 are respectively opened on both sides of the inner wall of the adjustment cup 2, and an adjusting rod 22 is commonly penetrated inside the two guide inclined holes 21.

[0031] The fixing cup 3 is embedded in the inner side of the cabinet door, and the adjusting cup 2 is sleeved with the fixing cup 3. The fixing cup 3 is provided with an adjusting screw 31 which is perpendicular to the adjusting rod 22 and is threadedly sleeved with the adjusting rod 22. The adjusting screw 31 is rotated to drive the adjusting rod 22 to move axially thereon. When the adjusting rod 22 moves, it contacts the guiding inclined hole 21 to drive the adjusting cup 2 to slide inside the fixing cup 3, so as to adjust the size of the gap between the cabinet body and the cabinet door. The reverse mounting seat 1, the adjusting cup 2 and the fixing cup 3 are all provided with mounting platforms, and the fixing cup 3 and the reverse mounting seat 1 are respectively fixed on the inner side of the cabinet door and the outer side of the cabinet side panel through the mounting platforms. The mounting platform on the adjusting cup 2 slides close to the inner side of the cabinet door. When in use, two side panels are installed inside the cabinet body, so that a hidden partition is formed between the side panel and the side wall of the cabinet body. The product is installed on the outer side of the side panel, that is, inside the hidden partition. See Figure 2 and Figure 3 Compared with conventional hinges installed on the inside of the cabinet side panel, this product is installed on the outside of the side panel, which is more concealed, keeps the cabinet clean and convenient for storage. It is especially suitable for hidden insert doors, solving the problem of reverse rotation of hinges.

[0032] It is particularly suitable for multifunctional furniture and smart furniture. This type of furniture has too many structural parts. In order to install the structural parts outside the cabinet and ensure the cleanliness of the cabinet, this product just solves this problem. In addition, this product can be used in narrow spaces. In order to facilitate the adjustment of the size of the door gap, the adjustment function is specially designed inside the fixed cup 3 and the adjustment cup 2. The size of the door gap can be adjusted by rotating the adjustment screw 31.

[0033] As a specific technical solution of this embodiment, both sides of the fixed cup 3 are provided with an adjusting rod guide hole 34 perpendicular to the adjusting rod 22. The two ends of the adjusting rod 22 pass through the guiding inclined hole 21 and are then inserted into the inside of the adjusting rod guide hole 34. Since the guiding inclined hole 21 can control the adjusting rod 22 to avoid rotational movement, the setting of the adjusting rod guide hole 34 further increases the stability of the adjusting rod 22. The opening direction of the guiding inclined hole 21 can determine the sliding direction of the adjusting cup 2 driven by the adjusting rod 22 when it moves on the adjusting screw 31. Figure 4 When the top end of the guide inclined hole 21 is located behind the adjusting rod 22 and the bottom end is located in front of the adjusting rod 22, when the adjusting rod 22 moves upward, it contacts the guide inclined hole 21 to drive the adjusting cup 2 to move forward. When the adjusting rod 22 moves downward, it contacts the guide inclined hole 21 to drive the adjusting cup 2 to move backward. The inclination amplitude of the guide inclined hole 21 can determine the adjustment amplitude of the adjusting cup 2.

[0034] As a specific technical solution of this embodiment, on both sides of the fixed cup 3, there are provided at least one frustum 35. Inside the frustum 35, there is a riveted guiding rivet post 36. On both sides of the adjusting cup 2, there are provided adjusting cup guiding holes 23 corresponding to the frustum 35. The adjusting cup guiding holes 23 are perpendicular to the adjusting rod guiding holes 34. One end of the guiding rivet post 36 away from the frustum 35 extends into the adjusting cup guiding holes 23. The guiding rivet post 36 is fixed inside the frustum 35 and inserted into the adjusting cup guiding holes 23, which is used to limit the movement direction of the adjusting cup 2, so that the adjusting cup 2 can only slide back and forth inside the fixed cup 3 and cannot move up and down, ensuring the stability during use.

[0035] As a specific technical solution of this embodiment, the middle part of the adjusting rod 22 is in the shape of a nut. Refer to Figure 6 , the middle part of the adjusting rod 22 is in the shape of a nut. When rotating the adjusting screw 31, since the adjusting screw 31 itself cannot move up and down, the adjusting rod 22 is pushed by the adjusting screw 31 to move up and down.

[0036] As a specific technical solution of this embodiment, inside the fixed cup 3, there is a U-shaped boss 37 provided. Inside the adjusting cup 2, there is a U-shaped guiding hole 24 sleeved with the boss 37. The setting of the boss 37 is not only used for installing the adjusting screw 31, but also can limit the adjusting cup 2 in cooperation with the U-shaped guiding hole 24, making the adjusting cup 2 more stable when sliding.

[0037] As a specific technical solution of this embodiment, the end of the adjusting screw 31 away from the nut is a smooth rod 32 with a diameter smaller than its main body, and one end of the smooth rod 32 penetrates through the boss 37 and is installed with a fixing piece 33. The fixing piece 33 cooperates with the smooth rod 32 to limit the axial movement of the adjusting screw 31, so that the adjusting screw 31 can only perform circumferential movement.

[0038] As a specific technical solution of this embodiment, the rotating arm 11 includes a connecting arm one 111 and a connecting arm two 112. The connecting arm one 111 and the connecting arm two 112 are respectively rotatably arranged inside the reverse mounting seat 1 through a rotating pin 101. A return torsion spring 114 is also sleeved on the rotating pin 101 connected to the connecting arm two 112. The setting of the return torsion spring 114 enables the connecting arm two 112 to automatically rebound when the cabinet door needs to be opened or closed in the semi-open state. Inside the reverse mounting seat 1, there is a damper 12 provided. One end of the connecting arm one 111 is in transmission connection with the piston inside the damper 12. The other end of the connecting arm one 111 extends into the adjusting cup 2. One end of the connecting arm two 112 extends into the adjusting cup 2 and is jointly and movably clamped inside the adjusting cup 2 with one end of the connecting arm one 111 through a U-shaped rotating pin one 113. Refer toFigure 7 and Figure 8 When the fixed cup 3 drives the adjustable cup 2 to rotate, both the first connecting arm 111 and the second connecting arm 112 make adaptive follow-up movements. At the same time, the second connecting arm 112 pulls or pushes the piston inside the damper 12 to achieve deceleration and positioning.

[0039] In summary, for this reversely installed hinge, the product can be installed on the outer side of the side plate through the reverse mounting seat 1, with good concealment, ensuring the neatness inside the cabinet, facilitating storage, and integrating a door gap adjustment mechanism inside the fixed cup 3 and the adjustable cup 2. The structure is concise and compact, further ensuring the concealment of the product. By rotating the adjustment screw 31, the size of the door gap can be adjusted, ensuring the closing effect of the cabinet door and the cabinet body. When the door gap becomes larger, there is no need to replace the entire cabinet body, with low usage costs, meeting economic benefits, and having broad application prospects.
