Description

Technical Field

[0001] The utility model relates to the technical field of hinges, and in particular to a buffer hinge structure. Background Art

[0002] In existing furniture cabinet door structures, damping hinges are usually installed to prevent the cabinet door from colliding with the door frame and generating loud noise when closing, and to effectively prevent the hand from being pinched when closing the cabinet door.

[0003] For example, Chinese patent document 2023201228984 discloses a hinge structure with bidirectional buffering. The damper of the hinge is installed in the groove on the surface of the first hinge monomer, and then needs to be covered and fixed with a cover. This fixing method is easy to be stretched open and damaged over time. Moreover, after the damper is fixed, one end is hinged to the adapter, but the other end is fixedly pressed against the inner wall of the first hinge monomer, and the depth of the piston rod cannot be adjusted, so the adjustment is impossible.

[0010] In the above-mentioned buffer hinge structure, a fixing block is provided on one side of the second mounting seat, a second mounting hole is opened on the fixing block, and the first mounting hole and the second mounting hole are both bar-shaped holes.

[0011] The beneficial effect of the present invention is that by arranging a damper plug-in cavity in the first mounting seat, the damper can be plugged into the damper plug-in cavity from the opening at one end for fixation, without the need for traditional grooving and covering the installation and fixation with a cover body, thereby preventing the damper from detaching, extending the service life, and making the structure more stable and firm.

Moreover, the adjusting member 5 can cover one end of the damper inserting cavity 9 and press the damper 10 in a telescopic manner, thereby adjusting the buffering strength of the damper 10, and having a more compact structure.

[0019] Furthermore, the adjusting member 5 of this embodiment adjusts the pressure of the top-pressing damper 10 , thereby adjusting the tightness of the damper 10 in the damper inserting cavity 9 .

[0020] In this embodiment, a damper mounting section 4 is provided along the length direction of the first mounting seat 1, and a first mounting hole 6 is provided on both sides of the damper mounting section 4. A damper plug-in cavity 9 is opened inside the damper mounting section 4, and a through hole is provided at one end of the damper plug-in cavity 9, and an adjustment hole 8 is provided at the other end. The adjustment member 5 is threadedly connected to the adjustment hole 8, and the adjustment hole 8 can accommodate the damper 10 to pass through; the adjustment member 5 can adjust the position by rotating in the adjustment hole 8, thereby realizing the expansion and contraction of the adjustment member 5 in the adjustment hole 8, so that the adjustment member 5 can adjust the pressure of the top pressure damper 10.

[0021] The aperture of the adjustment hole 8 in this embodiment is the same as the inner diameter of the damper plug-in cavity 9, so that the damper 10 is inserted into the damper plug-in cavity 9 from the adjustment hole 8, and then the adjustment hole 8 is blocked by the adjustment member 5 to prevent the damper 10 from detaching, thereby fixing the damper 10 in the damper plug-in cavity 9.

[0022] The adjusting member 5 of this embodiment is a screw or a bolt. By rotating the screw or the bolt, the screw or the bolt is extended and retracted in the damper inserting cavity 9 , thereby pressing the damper 10 .

[0023] This embodiment also includes a second mounting base 3, on which a first swing arm 12 and a second swing arm 13 are hinged. The first swing arm 12 is located above the second swing arm 13, and the first swing arm 12 and the second swing arm 13 are both hinged to the hinge base 2. A damper hinge base 14 is provided on the side of the second swing arm 13 away from the first swing arm 12. The damper hinge base 14 is hinged to a connecting rod base 15, and the damper 10 extends to one end outside the first mounting base 1 and is hinged to the connecting rod base 15; the second mounting base 3 is used to be installed on the cabinet door, and the first mounting base 1 is installed on the cabinet body, so that when the second mounting base 3 swings, it can pull the damper 10, thereby playing a buffering role.

The piston head divides the interior of the cylinder body into two hydraulic chambers. The piston head is provided with a one-way valve. A piston rod is provided at one end of the piston head. The piston rod extends to the outside of one end of the cylinder body and corresponds to the adjusting member 5. The other end of the cylinder body is provided with a connecting shaft hinged to the connecting rod seat 15. A spring is sleeved on the connecting shaft. One end of the spring presses against the inner wall of the damper plug-in chamber 9, and the other end presses against the cylinder body. The damper 10 of this embodiment is a product currently available on the market, and its specific structure will not be repeated here. By rotating the adjusting member 5 to adjust the tightness of the piston rod, the space of the hydraulic chamber inside the cylinder body is changed, thereby adjusting the buffering force.

[0026] In some embodiments, for products using a spring damper, the pressure between the cylinder and the spring can be adjusted by rotating the adjusting member 5 to change the buffering force.
