A damping hinge, when the device needs to be used, the user first installs the combined body B, the user puts the torsion spring 6 on the surface of the U-shaped groove 203 on the surface of the first coupling member 2, and installs the first part of the torsion spring 6 A coupling member 2 is put into the inner groove 101 of the arm member 1, the first coupling member 2 and the arm member 1 penetrate the first coupling member second circular hole 202, the first symmetrical circular hole 102 and the twist through the first pin 8 The spring 6 is fixed around the inner hole of the coil. After the first coupling member 2 is installed, the user installs the second coupling member 3. The second coupling member 3 is also placed inside the inner groove 101 of the arm member 1, the second coupling The piece 3 and the arm piece 1 are fixed through the second circular hole 302 and the second symmetrical circular hole 103 of the second connecting piece through the first pin 8. After the second coupling piece 3 is installed, the user installs the oil cylinder 5 , The cylinder 5 is pressed into the circular cavity 403 of the cylinder slide 4, and then the cylinder slide 4 is put into the inner groove 101 of the arm 1, the cylinder slide 4 and the arm 1 pass through the second pin 9 through the first The three symmetrical round holes 104 are used to fix it. After the installation of the cylinder slide 4 is completed, the user-structure switch 7 is installed at the switch mounting holes 106 on both sides of the arm 1 to complete the installation of the combined body B:

Opening action, shown in FIG. 10; when the hinge body A rotates in the opening direction, the second coupling member 3 rotates in the outward direction of the groove with the second symmetrical circular hole 103 of the arm member 1 as the axis, and the The curved tail 301 will leave the special-shaped convex body 401 on the cylinder slide 4, and the elastic force of the telescopic spring 503 in the cylindrical body of the cylinder 5 causes the piston rod 501 to push out and drive the cylinder slide 4 in the groove of the arm 1 to the arm 1 The tail moves, and when the main body A is opened, the hinge returns to the state before closing.

The closing action is shown in Figure 3; when the hinge body A (fixed door panel) rotates about 30 degrees in the closing direction, the torsion force of the torsion spring 6 installed in the combined body B (fixed inside the door cabinet) drives the body A toward Rotating in the closing direction, the first coupling member 2 and the second coupling member 3 are driven by the hinge body A to rotate about the first symmetrical circular hole 102 and the second symmetrical circular hole 103 on the arm member 1, the second coupling member 3 When the second symmetrical round hole 103 of the arm member 1 is used as the axis to rotate in the direction of the inner groove 101, the bent tail 301 on the second coupling member 3 will interfere with the cylinder slide 4 installed in the inner groove 101 of the arm member 1 The special-shaped convex body 401 drives the cylinder slide 4 to move along the inner groove 101 of the arm 1 to the head of the arm 1, and the top surface of the piston rod 501 of the cylinder 5 mounted in the circular cavity 403 of the cylinder slide 4 is supported ( The top of the piston rod 501 of the oil cylinder 5 touches the outer ring of the torsion spring 6), so that the resistance of the oil cylinder 5 is transmitted to the inner wall of the inner bottom of the circular cavity of the cylinder slide 4 through the outer round end surface of the cylinder body of the oil cylinder 5 to slow down the oil cylinder The moving speed of the sliding seat 4 and the slowing down of the moving speed of the oil cylinder sliding seat 4 slow down the rotation speed of the hinge body A through the first coupling member 2 and the second coupling member 3, so that the door panel closes slowly and gently, eliminating the collision between the door panel and the door cabinet sound.

Function description of the switch: As shown in FIGS. 13-15, before the hinge body A closes, the fourth symmetrical circular hole 105 on the arm 1 is used as the axis to turn the switch 7 in the off direction, so that the The first cylinder 701 is caught in the semi-circle of the switch member mounting hole 106 of the arm member 1 in the off direction, so that the first cylinder 701 of the switch member 7 and the convex body 402 of the cylinder slide 4 are on the same parallel line, and the hinge body A is closed The rotary carriage 4 with a cylinder moves toward the left end of the arm member 1. When the inclined surface of the convex body 402 of the cylinder carriage 4 comes into contact with the slope of the first cylinder 701 of the switch member 7, the moving pulling force of the cylinder carriage 4 presses the switch member 7 A cylinder 701 is pushed high outwards, so that the convex body 402 of the cylinder slide 4 is forcibly passed, the switch 7 is pressed outward and released, and the top of the first cylinder 701 is reset to the top of the cylinder lower than the top surface of the convex body 402 of the cylinder slide 4 When the hinge body A is opened and opened, the side of the convex body 402 of the cylinder slide 4 will be touched by the first cylinder 701 of the switch 7 to restrict the movement of the cylinder slide 4 to the right end of the arm 1, and then when the hinge body A starts again Closing action, the buffer function of the hinge has been limited at this time (if you want to restore the buffer function, you can turn the switch 7 in the open direction, when the switch 7 is in the open direction, the first cylinder 701 of the switch 7 can be The convex body 402 of the cylinder slide 4 is completely avoided, and it will not interfere with the normal damping movement and reset movement of the cylinder slide 4, when the switch 7 is in the off direction, the first cylinder 701 forcibly passes through the convex body 402 of the cylinder slide 4 At this time, the rear side of the convex body 402 of the cylinder slide 4 is contacted by the first cylinder 701. When the hinge body A is opened again, the movement of the cylinder slide 4 is restricted after resetting. When the hinge body A is closed again, the joint The bending tail 301 on the second connecting piece 3 rotates inwardly of the arm without being affected by the buffer resistance of the cylinder slide 4, and the closing force and speed of the hinge body A will not be affected.

This kind of damping hinge is provided with a buffer component inside the arm, which slows down the movement speed of the hinge body and makes the door panel close slowly and softly, eliminating the impact sound of the door panel and the door cabinet; by combining the switch parts on the surface of the body, the use of Personnel can control the sliding speed of the cylinder slide inside the arm member through the switch member, so that it can control the movement speed of the hinge body, so that the movement speed of the hinge body can be controlled and adjusted by the switch member.

Finally, it should be noted that the foregoing is only preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it is still The technical solutions described in the foregoing embodiments can be modified, or some of the technical features can be equivalently replaced. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of this application shall be included in the scope of protection of this application.
