Description

Technical Field

[0001] The utility model relates to the technical field of hardware accessories, in particular to a furniture buffer device with double buffering for opening and closing doors. Background Art

[0002] Buffers are also used in cabinet doors, primarily to slow down and cushion the movement during opening and closing. Without a buffer, the cabinet door would collide with the cabinet body, creating a clattering sound and shortening the door's lifespan. Some people try to prevent this by installing a buffer on the cabinet body, but this approach compromises the cabinet's aesthetics. Furthermore, this approach doesn't provide ideal cushioning, resulting in a loud clattering sound that doesn't meet design requirements.

[0003] For example, a furniture buffer with the Chinese document announcement number CN207813350U includes a buffer component 10, a first hinge seat 20 and a second hinge seat 30 respectively connected to the two ends of the buffer component 10, the first hinge seat 20 is arranged on the furniture wall 50, and the second hinge seat 30 is arranged on the door 60. A connecting portion 40 is also provided between the buffer component 10 and the second hinge seat 30, the connecting portion 40 is fixedly connected to the buffer component 10, and the connecting portion 40 is rotatably connected to the second hinge seat 30, and a collision portion 41 is also provided at the end of the connecting portion 40; this structure can reduce the impact force and impact sound of the door when closing for the first time through the buffering effect of the buffer component, and a damper is also provided. The damper and the collision portion are used in conjunction to reduce the impact force and impact sound of the door when closing for the second time, thereby achieving a double buffering effect; however, this structure can only achieve double buffering when the door is closed. When the door body is opened by excessive external force, an impact still occurs, resulting in noise.

[0004] Therefore, further improvement is needed. Utility Model Content

[0024] like Figures 1 to 3 The illustrated furniture buffer device with dual buffering for door opening and closing comprises a first hinge seat 10 for connecting to the cabinet door and a second hinge seat 20 for connecting to the cabinet body. A buffer component 30 is disposed between the first hinge seat 10 and the second hinge seat 20 to provide a buffering effect when the cabinet door is flipped. The first hinge seat 10 comprises a fixed seat 11 and a swing arm 12, the fixed seat 11 being rotatably connected to the swing arm 12. This structure is prior art and will not be explained in detail.

[0025] The fixing seat 11 is provided with a first damper 40 and a second damper 50. The swing arm 12 is provided with a first action end 121 and a second action end 122. When the cabinet door is flipped and closed, the first action end 121 abuts against the first damper 40.

[0026] When the furniture cushioning device is flipped and closed, the cushioning component 30 first reduces the flipping speed of the cabinet door through its cushioning effect. When the cabinet door is closed and almost fits against the cabinet body, the first action end 121 of the swing arm 12 cooperates with the first damper 40 to provide a second level of cushioning for the furniture cushioning device when flipping and closing.

[0027] Similarly, when the furniture buffer device is flipped open, the flipping speed of the cabinet door is first reduced by the buffering effect of the buffer component 30 until the cabinet door is opened to almost the maximum angle. The second action end 122 on the swing arm 12 cooperates with the second damper 50, and the second damper 50 provides a second level of buffering for the furniture buffer device when it is flipped open.

[0028] The buffer component 30 is a cylinder, and both ends of the buffer component 30 are provided with external threads. One end of the buffer component 30 is screwed to the swing arm 12, and the other end is screwed to the second hinge seat 20.

[0029] The first acting end 121 is arranged at the front end of the swing arm 12, and the second acting end 122 is arranged at the rear end of the swing arm 12. The first mounting cavity 111 and the second mounting cavity 112 are arranged side by side on the fixed seat 11. The first damper 40 is arranged in the first mounting cavity 111, and the cylinder end of the first damper 40 at least partially extends out of the first mounting cavity 111 so that the first acting end 121 abuts against the first damper 40. The second damper 50 is arranged in the second mounting cavity 112, and at least part of the cylinder end of the second damper 50 extends out of the second mounting cavity 112 so that the second acting end 122 abuts against the second damper 50.

[0030] A first damping adjusting member 60 is provided at the end of the first damper 40 away from the cylinder end, and the first damping adjusting member 60 is provided with an external thread and is screwed to the first mounting cavity 111 through the external thread. A second damping adjusting member 70 is provided at the end of the second damper 50 away from the cylinder end, and the second damping adjusting member 70 is provided with an external thread and is screwed to the second mounting cavity 112 through the external thread. The first damping adjusting member 60 and the second damping adjusting member 70 are also provided with a rotating part; the rotating part is preferably a knob head, and the outside of the knob head is provided with anti-slip grooves; the installer can drive the position of the first damper 40 or the second damper 50 by manually rotating the first damping adjusting member 60 or the second damping adjusting member 70 to improve the buffering and unloading effects of the furniture buffer device.

[0031] The first action end 121 is arranged on the left side of the front end of the swing arm 12, and a rotation hole is set on the first action end 121. A hinged double-ear plate 113 is set on the front side of the first installation cavity 111, and the rotation hole is rotatably connected to the hinged double-ear plate 113 through a rotation pin.

[0032] The second action end 122 is arranged on the right side of the front end of the swing arm 12. The fixed seat 11 is provided with an active cavity 114, and the active cavity 114 is connected to the second installation cavity 112, so that when the furniture buffer device is flipped open, the second action end 122 enters the active cavity 114 and abuts against the second damper 50.

[0033] You should know that, see Figure 4-5 , are two installation implementation methods of the furniture buffer device, which can be applied to flip-up cabinet doors and flip-up cabinet doors.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
