[0046] Both ends of the cover 11 are provided with clamping strips 1101, and the clamping strips 1101 are engaged with the clamping grooves 1001 on the upper hinge pin 9 and the lower hinge pin 10. The clamping grooves 1001 are annular grooves, and the clamping strips 1101 are fan-shaped structures sleeved on the outer side of the annular grooves. The clamping strips 1101, the clamping grooves 1001, and the upper hinge pin 9 and the lower hinge pin 10 are coaxially arranged.

[0047] The cooperation between the clamping strip 1101 and the clamping groove 1001 can effectively fix the upper hinge pin 9 and the lower hinge pin 10, preventing them from accidentally loosening or falling off during use, thereby improving the stability of the entire hinge. Due to the tight cooperation between the clamping strip 1101 and the clamping groove 1001, the sliding friction of the upper hinge pin 9 and the lower hinge pin 10 during movement can be reduced, thereby reducing the generation of noise. The design of the clamping strip 1101 makes the maintenance and replacement of hinge components simpler because it is not necessary to disassemble the entire hinge structure, and only the clamping strip 1101 and the relevant clamping groove 1001 need to be replaced or repaired.

[0048] The design of the clamping strip 1101 and the clamping groove 1001 can make the appearance of the hinge more tidy and integrated. Because they can be hidden inside the hinge, without occupying external space, and at the same time reduce the possibility of external decorative parts. Due to the tight fit of the clamping strip 1101 and the clamping groove 1001, it can reduce the damage of the hinge components caused by loosening or wear, thereby improving the durability of the entire hinge. The design of the clamping strip 1101 can make the upper hinge pin 9 and the lower hinge pin 10 easier to be positioned and installed, because they can be directly sleeved into the clamping groove 1001, reducing the alignment and adjustment work during the installation process. Due to the coaxial setting of the clamping strip 1101, the clamping groove 1001, the upper hinge pin 9 and the lower hinge pin 10, it can ensure that the hinge can maintain good fit and performance at different installation angles and positions.

[0049] By rotating the adjustment screw A3, the slide seat 2 is driven to move and adjust in the left-right direction, driving the fixed seat 4 to adjust in the left-right direction; by rotating the adjustment screw B6, the fixed seat 4 is driven to move and adjust in the up-down direction; when rotating the adjustment screw C7, due to the axial limit effect of the adjustment screw C7 on the slide seat 2, the part of the fixed seat 4 connected to the adjustment screw B6 will move forward or backward to perform the forward-backward swing adjustment.

[0050] By rotating the adjustment screw A3 to adjust the left-right movement of the slide seat 2, by the adjustment screw B6 to adjust the up-down movement of the fixed seat 4, and by the adjustment screw C7 to achieve the forward-backward swing adjustment, the hinge can be accurately adjusted in multiple directions to meet different requirements such as the opening and closing angles, angles and positions of the door panel. By adopting different adjustment methods, the position and angle of the hinge can be flexibly adjusted according to specific requirements to meet the requirements of different door panels and furniture designs, enhancing the applicability and versatility of the hinge. By rotating the adjustment screw for adjustment, the operation is simple and convenient, without the need for additional tools or complex operation steps, improving the installation and debugging efficiency. Due to the adoption of multiple adjustment methods, precise position and angle adjustment can be achieved, making the adjustment of the hinge more accurate and ensuring the opening and closing effect and use experience of the door panel. The design of different adjustment screws makes the maintenance of the hinge more convenient. Only by operating the corresponding screws can the adjustment and maintenance in different directions be completed, reducing the complexity and cost of maintenance. Through the multi-direction adjustment method, it can ensure the stability of the hinge at different positions and angles, avoiding unstable phenomena caused by inaccurate positions or inappropriate angles, and improving the stability and safety of the entire door panel.

[0051] The fixing seat 4 is embedded with a buffer plate 403 that cooperates with the piston rod on the damper 12 to abut against the top. The buffer plate 403 embedded in the fixing seat 4 can provide a buffering effect during the opening and closing process of the door panel, reduce the impact on the door panel and furniture related to the hinge, protect the furniture structure, and extend the service life. The design of the buffer plate 403 can reduce the impact noise during opening and closing, and improve the quietness and comfort of the home.

[0052] Magnetic blocks A404 are embedded on the fixed seat 4 and on both sides of the buffer plate 403, and magnetic blocks B805 that cooperate with the magnetic blocks A404 are embedded on the movable seat 8. The design of embedded magnetic blocks can help the door panel to be quickly adsorbed and fixed in place when closed, thereby improving the stability and safety of the door panel. The application of magnetic blocks can ensure that the door panel fits tightly when closed, increasing the stability of the door panel and avoiding shaking or loosening caused by inaccurate position of the door panel. With the above design, the hinge opens and closes more smoothly, the operation is smoother, the user experience is improved, and the quality of the furniture is improved.

[0053] The adjustable pin-type silent hinge has a mounting seat 1 as the main fixed part of the hinge, which is installed on the cabinet body with screws through the mounting holes 105 at the four corners. The slide 2 is connected to the mounting seat 1 through the adjustment screws A3 and can slide in the side slot 104. One end of the slide 2 is movably connected to the fixed seat 4 through the pin 5. The fixed seat 4 can slide along the slide 2 to achieve horizontal and vertical adjustment. The fixed seat 4 is connected to the slide 2 through the adjustment screws B6 and can move in the vertical direction. In addition, it is also connected to the slide 2 through the adjustment screws C7, which allows the fixed seat 4 to swing back and forth under the axial limit of the slide 2.

[0054] The movable seat 8 is hinged to the fixed seat 4 through the upper hinge pin 9 and the lower hinge pin 10, so that the cabinet door can be opened and closed. The movable seat 8 is embedded with a damper 12. When the cabinet door is closed, the damper 12 can provide a buffering effect to reduce noise and vibration. The cover 11 is used to position the upper hinge pin 9 and the lower hinge pin 10 on the fixed seat 4 to prevent them from loosening during use. The cover 11 has a positioning strip 1101, which cooperates with the positioning groove 1001 on the upper hinge pin 9 and the lower hinge pin 10 to ensure their correct position.
