When assembled in place, the spring 9 is located between the fixing member 26 and the left and right fixed seats. When the user opens the door, the upper and lower fixed seats 4 and the upper and lower adjustment seats 2 are driven to move, thereby driving the first rocker arm 101 and the second rocker arm 102 to move. At this time, the free end of the first rocker arm 101 slides in the second slide groove 23 toward the direction away from the bottom surface of the second mounting groove 19 through the second slider 21, thereby driving the pull rod 10 to move, thereby causing the fixing part 26 fixed on the pull rod 10 to compress the spring 9. When the user's hand leaves the door body, the spring 9 recovers, thereby resetting the first rocker arm 101 to drive the upper and lower fixed seats 4 to reset, and the door body 100 can be reset and closed.

[0041] Preferably, a sleeve 27 is provided on the outer side of the spring 9, and a damping rod 28 is fixed in the sleeve 27. The damping rod 28 is located on the side of the fixing part 26 away from the left and right adjustment seats 3. When assembled in place, the movable end of the damping rod 28 is against the pull rod 10 and the damping rod 28 is in a compressed state at this time. A fixing assembly 3a for fixing the sleeve 27 is provided on the left and right fixing seats 5. By setting the damping rod 28, a damping force can be provided when the door body is closed, so that the door body 100 closes slowly, preventing the door body 100 from having excessive rebound force and damaging the door body or pinching the hand.

[0042] Preferably, the fixing assembly 3a includes a sleeve seat 3a1 for fixing the sleeve 27, and a tensioning block 3a2 for cooperating with the fixing piece 26 to compress the spring 9; the tensioning block 3a2 is provided with a through hole 30 for the pull rod 10 to pass through, and the aperture of the through hole 30 is smaller than the outer diameter of the spring 9 to prevent the spring 9 from moving when the spring 9 is compressed.

When the door body needs to be adjusted up and down, the upper and lower adjusting bolts 61 are loosened by a screwdriver, and then the upper and lower positioning bolts 62 are turned to push the upper and lower adjusting seat 2 up or down, and the upper and lower positioning bolts 62 are turned to push the upper and lower adjusting seat 2 downward. At this time, the upper and lower adjusting seat 2 can be adjusted to move up and down in the upper and lower movable grooves 11. At this time, if the front and rear position of the door body is further adjusted, the upper and lower adjusting seat 2 can be pushed to slide back and forth on the upper and lower positioning bolts 62 below, thereby realizing the front and rear movement of the door body. In order to facilitate the front and rear movement of the upper and lower adjusting seat 2, the upper and lower side walls of the upper and lower adjusting seat 2 are both provided with platforms 2a with smooth surfaces.The left and right adjustment components 7 include two left and right adjustment bolts 71 respectively provided at the upper and lower ends of the left and right adjustment seats 3. In addition, the left and right adjustment components can also be implemented by using a micro motor in conjunction with a rack or a micro motor in conjunction with a rack in conjunction with a screw. For example, the screw is rotated left and right in the left and right movable grooves, and the left and right adjustment seats are slidably sleeved with the screw threads, which can also achieve the purpose of adjusting the left and right adjustment seats. The left and right adjustment bolts 71 pass through the left and right adjustment seats 3 and are rotatably connected thereto. A second screw hole 39 that cooperates with the left and right adjustment bolts 71 is provided on the bottom surface of the left and right movable grooves 12. In order to reduce the setting of the rotating connected parts, the head placement groove 40 for limiting the left and right adjustment bolts 71 is opened on the upper and lower side walls of the left and right adjustment seats 3, and the placement groove 40 is close to its opening. A second notch 41 is provided on the side wall for the screw portion of the upper and lower adjusting bolts 61 to move, and a left and right adjusting hole 42 is provided on the left and right adjusting seat 3 corresponding to the head of the left and right adjusting bolts 71.

The screw portion of the left and right adjusting bolt 71 is threadedly connected to the left and right adjusting seat 3. When it is necessary to adjust the left and right position of the door body, the adjusting tool is inserted into the left and right adjusting holes 42 and the left and right adjusting bolts 71 are rotated. At this time, the head of the left and right adjusting bolt 71 rotates freely in the mounting groove 40 without linear displacement, and its screw The left and right adjusting holes 32 and the left and right adjusting holes 42 are arranged side by side along the up and down directions of the left and right adjusting seats 3, and the left and right adjusting holes 42 are connected with the placement grooves 40 and are opposite to the second notch 41. Compared with the traditional hinge itself, which is directly fixed to the door body 100 and the door frame 200 with screws, the hinge protrudes obviously, which greatly reduces the beauty of the door, and the door body 10 cannot be adjusted after it is fixed. Once the fixed position of the door body 100 is too high or too low or too left or right, the door body 100 cannot be opened and closed normally. At this time, the door needs to be re-installed. The door 100 requires disassembling the door body and re-adjusting the hinge's fixed position, which makes installation extremely inconvenient. However, the present invention adjusts the door body's position by adjusting the movement of the upper and lower adjustment bases 2 and the left and right adjustment bases 3, eliminating the need to disassemble the door body or re-fix the screws. This ensures the safety and stability of the door 100. Conventional hinges are formed from sheet metal stamping, which has elastic movement and is prone to noise during rotation. The present invention, however, uses a hinged connection with two rocker arms in a block-shaped structure, significantly improving rigidity, eliminating noise, providing a quiet and concealed appearance, and significantly enhancing the connection between the hinge and the door body. To prevent dust, dust caps 43 are provided at the upper and lower ends of the upper and left and right fixing bases after assembly.
