The inside of the rod 6 and the end of the bumper 2 are articulated with the short rod 5 and the long rod 6, that is, hinged by the rivets of the short rod 5 and the long rod 6. The telescopic end of the buffer 2 and the left and right sides of the triangular connector 8 Side hinged. The triangular connecting piece 8 is provided with elastic pressing members 9 and pulleys 10 hinged to the left and right sides thereof. The left and right sides of the triangular connecting piece 8 are provided with guide grooves 81. The guide groove 81 is internally provided with two ends fixed on the long rod 6. The first rivet 11, the guide groove 81 and the first rivet 11 limit the movement trajectory of the triangular connecting member 8 to ensure that the buffer 2 articulated with the triangular connecting member 8 performs a telescopic movement according to the moving trajectory. A small cam 12 is fixed in the hinge arm 3 by rivets, the pulley 10 slides on the surface of the small cam 12, and the bumper 2 is pushed against the bumper 2 by the triangular connecting member 8, which causes the bumper 2 to perform a compression movement when the hinge is closed, thereby generating a buffer. ; The end of the elastic pressing member 9 is pressed against the first rivet 11 to ensure that the pulley 10 always fits on the surface of the small cam 12 and slides.

In order to make the pulley 10 slide uniformly on the surface of the small cam 12 to achieve a better buffering effect, the surface shape of the small cam 12 is set to be wavy, and the bottom of the triangular connecting member 8 is arc-shaped to match the surface of the small cam 12.

Preferably, the elastic pressing member 9 is a torsion spring, and the guide groove 81 is a U-shaped groove.

In order to facilitate the installation and disassembly of the buffer 2, the end and the retractable end of the buffer 2 are provided with an opening buckle 21, and the end of the buffer 2 is buckled on the rivet fixed to the long rod 6 through the opening buckle 21, and the expansion and contraction of the buffer 2 The end is buckled on the rivet fixed to the triangular connecting piece 8 through the opening buckle 21, and the buffer hinge is converted into a normal hinge without a buffer function after the buffer 2 is removed. The flexible buckle of the buffer hinge and the ordinary hinge can be realized through the opening buckle 21.

The front end of the hinge cup 1 and the girder 7 are hinged by rivets, and the middle section of the girder 7 and the middle section of the long rod 6 are hinged by rivets. The beam 7 is provided with a spring sleeve 13, the spring sleeve 13 is provided with a compressed spring 14, and the spring sleeve 13 The end of the spring 14 is against the eccentric wheel 15. The eccentric wheel 15 and the connecting member 16 are hinged by a pin. One end of the connecting member 16 is hinged by a pin with the end of the beam 7. The other end of the connecting member 16 and the hinge arm 3 are hinged by a rivet. . Specifically, after the spring 14 is compressed, it is loaded into the spring sleeve 13 and the front end of the spring 14 is positioned with a second rivet 17. The second rivet 17 is fixed on the beam 7 while supporting the front section of the spring sleeve 13 and the rear section of the spring sleeve 13. The bottom is provided with a third rivet 18 fixed on the girder 7. Preferably, two springs 14 are provided, and the elastic force output is more stable. When the hinge cup 1 pulls the beam 7 to move left and right, the connecting piece 16 articulated with the beam 7 also swings left and right. The swing of the connecting piece 16 drives the eccentric 15 to rotate left or right, and the spring sleeve 13 is driven by the eccentric 15 Reduce or give space for the spring 14 to return. The spring 14's elastic force in turn generates a force on the girder 7, which in turn exerts this force on the long rod 6 hinged to it, and the long rod 6 acts on this buffer 2 again. So as to promote the opening and closing of the hinge.

The hinge arm 3 is installed on the base 4. In order to facilitate the installation and removal of the hinge, the present application also includes a disassembly frame 19 nested in the inner wall of the hinge arm 3, as shown in FIG. The hook 191 has a first groove 41 matching the first inverted hook 191 on the bottom surface of the front end of the base 4.

The lower end of the iron hook 20 is provided with a second inverted hook 201, and the end of the base 4 is provided with the second The second groove 42 matched with the barb 201, and the small torsion spring 21 keeps the second barb 201 of the iron hook 20 and the second groove 42 on the base 4 in a locked state, and at the same time enables the disassembly rack 19 and The operation of combining and separating the base 4 is more convenient. In order to facilitate manual operation, a dial 16 is provided on the outside of the iron hook 14. The material of the dial 16 may be preferably plastic. The dial 16 and the iron hook 14 and the small torsion spring 15 are hinged to the end of the dismounting frame 13 through pins. During installation, the first barb 131 is snapped on the first groove, and the second barb 141 is snapped on the second groove 71, and the combination and assembly of the base 7 and the disassembly frame 13 is completed. When disassembling, manually push the dial 16 to overcome the elastic force of the small torsion spring 21, so that the second barb 141 is released from the second groove 71 and the first barb 191 is released from the first groove 41 The buckle completes the removal of the base 7 and the removal frame 13.

During installation, the hinge cup 1 is fixed on the door panel, the base 4 is fixed on the cabinet or the door frame, and other parts are assembled according to the connection relationship of this application.

This application works as follows:

When the door is opened, the hinge cup 1 pulls the short rod 5 and the girder 7, respectively. The short rod 5 drives the long rod 6 and the bumper 2 to which it is hinged. The bumper 2 pulls the triangular connector 8 so that the pulley 10 is on the surface of the small cam 12. Sliding forward, the buffer 2 is stretched at this time; the beam 7 drives the connecting piece 16 to swing forward, the eccentric wheel 15 rotates forward, and the spring 14 is compressed; in this process, the hinge cup 1 is pulled down, and other components The cooperation is stretched, swinged and rotated as much as possible, so that the door panel can be opened at the maximum angle, as shown in Figs. 2, 7 and 8.

When closing the door panel, the hinge cup 1 is given a backward closing pressure, which acts on the short rod 5 and the beam 7. The short rod 5 drives the long rod 6 and the bumper 2 which are hinged to the back, and the bumper 2 pushes the triangular connector. 8. Make the pulley 10 slide backward on the surface of the small cam 12, and the pulley 10 and the small cam 12 generate a bump against the buffer 2 through the triangular connecting member 8, and urge the buffer 2 to perform a compression movement when the hinge is closed, thereby generating a buffer. Make the door panel close slowly and quietly; the girder 7 drives the connecting piece 16 to swing backward, the eccentric wheel 15 rotates backward, giving the spring 14 a return space, and the returning elastic force of the spring 14 pushes the eccentric wheel 15 and the connecting piece 16 to swing backward, which promotes the hinge Close, as shown in Figures 1, 9 and 10.

The above technical features such as the buffer 2, the triangular connection 8, the pulley 10, and the small cam 12 together form the buffer structure of the present application, which is convenient for starting the buffer, and the process of opening and closing the hinge is relatively stable, ensuring a good buffer effect. The combination of the short rod 5, long rod 6, girder 7 and connector 16 makes the hinge openable at a larger angle, as shown in Figure 4, where line A is a straight line parallel to the mounting surface of the base 4, and line B It is a straight line parallel to the installation surface of the hinge cup 1. When the hinge is fully opened, the installation angle of the installation surface of the hinge cup 1 and the base 4 used to install the cabinet or the door frame is 155 degrees, so that the hinge can reach 155 degrees. Can be applied to a variety of applications, and the scope of application is wider.
