Advantageous effects

Compared with the prior art, the full-angle buffer hinge has the advantages that:

1. because the sliding part and the power lamination remain linkage state all the time, when the cabinet door is closed, the oil hydraulic cylinder as the buffer piece acts all the time, so that the full-angle buffer is realized, the speed of the cabinet door when closed is ensured to be soft and reasonable, the impact force is small, the service lives of the hinge and the cabinet door are prolonged, and the buffer effect can be produced at any angle.

2. The torsional spring provides closing power for the cabinet door.

3. Because the rod bodies of the power lamination and the oil hydraulic cylinder are both acted on the linkage piece, the linkage piece is set to be a metal piece, and the service life is long.

4. The full-angle buffer hinge is suitable for any buffer hinge of a cabinet door, and comprises a sliding-in buffer hinge with 1 section of force, 1.5 sections of force and 2 sections of force, a clamping buffer hinge, a bird button fast-assembling buffer hinge and a fixed buffer hinge.

Examples

The embodiment of the utility model is shown in fig. 1 to 8, and the full-angle buffer hinge comprises a hinge cup 1, an arm body 2, a swing arm 3 and a power lamination 6. One end of the swing arm 3 is rotationally connected with the hinge cup 1 through a first shaft body 51, and the other end of the swing arm 3 is rotationally connected with the arm body 2 through a third shaft body 4. One end of the power lamination 6 is rotatably connected with the hinge cup 1 through a second shaft body 52, and the power lamination 6 is also rotatably connected with the arm body 2 through a fourth shaft body 11. The arm body 2 is connected with a sliding part in a sliding way, a buffer piece is arranged on the sliding part, and the sliding part is linked with the power lamination 6. In this embodiment, both ends of the first shaft body 51 and the second shaft body 52 are connected and constitute the U-shaped shaft 5. The U-shaped shaft 5 is mounted on the hinge cup 1.

The third shaft body 4 is sleeved with a torsion spring 7, and an extension section 71 of the torsion spring 7 is contacted with the hinge cup 1.

The buffer is an oil hydraulic cylinder 9. The hydraulic cylinder 9 comprises a cylinder body 91 and a rod body 92 which are connected in a sliding manner, and the cylinder body 91 is fixed relative to the hinge cup 1. The top end of the rod 92 is matched with the sliding part.

The sliding part comprises a shell 8 and a linkage piece 10 which are connected, and the shell 8 is in linear sliding connection with the arm body 2. The cylinder body 91 of the hydraulic cylinder 9 passes through the housing 8, and the top end of the cylinder body 91 is pushed against the torsion spring 7. The top end of the rod body 92 of the hydraulic cylinder 9 is abutted against the stress end 101 of the linkage member 10. The linkage piece 10 is provided with a linkage buckling position 102, the power lamination 6 is provided with a power hook 63, and the power hook 63 is hooked on the linkage buckling position 102. The power hook 63 is provided at both ends thereof with a first through hole 61 and a second through hole 62, respectively, the second shaft body 52 passes through the first through hole 61, and the fourth shaft body 11 passes through the second through hole 62.

The linkage member 10 is a metal member, and the housing 8 is a plastic member. Since the power lamination 6 and the rod body 92 of the oil hydraulic cylinder 9 both act on the linkage member 10, the linkage member 10 is set to be a metal piece, and the service life is long.

The power lamination 6 is in the form of a sheet, the number of which is at least two and is arranged side by side, as shown in fig. 2.
