Detailed Implementation

[0018] like Figures 1 to 3 As shown, a hinge includes a door frame box 10, a door panel 20, and a connecting arm assembly 30. The connecting arm assembly 30 is movably connected to the door frame box 10, and the door panel 20 is connected to the connecting arm assembly 30. When the user pushes the door to open, the door panel 20 drives the connecting arm assembly 30 to move, and the connecting arm assembly 30 moves inside the door frame box 10, so that the door opens smoothly. When the door is closed, the connecting arm assembly 30 moves in the opposite direction, so that the door panel 20 returns to its original position, and finally the door closes. The structure is simple and the use is stable and convenient.

[0019] In specific implementation, the connecting arm assembly 30 includes a main connecting arm 31, a first auxiliary connecting arm 32, and a second auxiliary connecting arm 33. The main connecting arm 31 has a connecting slot 311 in its middle. One end of the first auxiliary connecting arm 32 has a first connecting through-hole 321 disposed within the connecting slot 311. Connecting through-holes 312 are symmetrically formed on both sides of the connecting slot 311. The connecting through-holes 312 correspond to the first connecting through-holes 321 and are hinged together by a connecting shaft passing through the connecting through-holes 312 and the first connecting through-holes 321, thereby allowing the first auxiliary connecting arm 32 to move movably. The second auxiliary connecting arm 33 is attached to the middle of the main connecting arm 31. The bottom of the main connecting arm 31 is recessed with a connecting recess 313. One end of the second auxiliary connecting arm 33 is provided with a first mounting through part 331. The first mounting through part 331 is disposed in the connecting recess 313. The connecting recess 313 is symmetrically provided with connecting openings 314 on both sides. The connecting openings 314 and the first mounting through part 331 are correspondingly provided. The connecting arm 33 is hinged to the first mounting through part 331 by a connecting shaft passing through the connecting openings 314 and the first mounting through part 331. Thus, the second auxiliary connecting arm 33 is movably connected to the bottom of the main connecting arm 31, thereby forming the connecting arm assembly 30. The structure is simple and the assembly is convenient.

[0020] In specific implementation, the door frame housing 10 has a recessed mounting groove 11 inside, and the connecting arm assembly 30 is disposed in the mounting groove 11. A first movable through hole 111 and a second movable through hole 112 are symmetrically provided on both sides of the mounting groove 11. The first movable through hole 111 is located above the second movable through hole 112. The other end of the first auxiliary connecting arm 32 has a second connecting through part 322, which corresponds to the first movable through hole 111 and is hinged to the first movable through hole 111 and the second connecting through part 322 via a connecting shaft, thereby allowing the first auxiliary connecting arm 32 to be movably connected in the mounting groove 11. The other end of the second auxiliary connecting arm 33 has a second mounting through part 332, which is connected to the second movable through hole 112. Correspondingly, the second auxiliary connecting arm 33 is hinged to the second movable through hole 112 and the second mounting through hole 332 via a connecting shaft, thereby allowing the second auxiliary connecting arm 33 to be movably connected in the mounting groove 11, and thus allowing the connecting arm assembly 30 to be movably connected in the mounting groove 11. The structure is simple and easy to assemble. In use, when the door is pushed: the first auxiliary connecting arm 32 rotates around the connecting shaft of the main connecting arm 31, and at the same time rotates around the first movable through hole 111 of the door frame box 10, so that the door gradually opens. The second auxiliary connecting arm 33 rotates around the connecting shaft of the main connecting arm 31, and at the same time rotates around the second movable through hole 112 of the door frame box 10, providing additional support and preventing the door from shaking. The entire connecting arm assembly 30 moves within the mounting groove 11, ensuring smooth door opening and reducing friction. When the door is closed: the first connecting arm 32 and the second connecting arm 33 rotate in opposite directions, so that the door returns to its original position smoothly. Due to the multi-axis hinge design, the hinge can achieve a smooth closing and reduce impact.

[0021] In practical implementation, the door panel 20 has symmetrical connecting slots 21 on both sides of its surface, and the main connecting arm 31 has symmetrical connecting blocks 315 protruding on both sides of its upper surface. The two connecting blocks 315 correspond to the two connecting slots 21, and the connecting blocks 315 are embedded in the connecting slots 21 for engagement, thereby connecting the door panel 20 to the main connecting arm 31. The structure is simple and the installation is convenient.

[0022] In practical implementation, a first buffer pad 34 is provided between the first connecting through part 321 and the connecting through hole 312, and a second buffer pad 35 is provided between the first mounting through part 331 and the connecting opening 314. In use, the first buffer pad 34 and the second buffer pad 35 can absorb the vibration and impact generated when opening and closing the door, effectively reducing the noise generated during the opening and closing of the door, and reducing the direct friction between metal parts, thereby reducing wear and extending the service life of the entire hinge assembly.

[0023] In summary, the connecting arm assembly 30 is movably connected to the door frame box 10, and the door panel 20 is connected to the connecting arm assembly 30. The connecting arm assembly 30 includes a main connecting arm 31, a first auxiliary connecting arm 32, and a second auxiliary connecting arm 33. The first auxiliary connecting arm 32 is movably connected to the middle of the main connecting arm 31, and the second auxiliary connecting arm 33 is movably connected to the bottom of the main connecting arm 31. The hinge structure of this utility model is simple, easy to assemble, and stable in use. Due to the multi-axis hinge design, the hinge can achieve smooth closing, reduce impact force, facilitate transportation, and protect the door.
