Description

Technical Field

[0001] This utility model relates to the field of door and window hardware accessories, and in particular to a furniture flipping device with an optimized buffer adjustment structure. Background Technology

[0002] Chinese patent CN202420217423.8 discloses a damping buffer structure for a furniture lift-up device. It includes a housing and a support arm mechanism, a force adjustment mechanism, an elastic mechanism, and a damping mechanism mounted on the housing. The support arm mechanism is located at the front end of the housing and provides opening and closing for the cabinet door. The force adjustment mechanism is located at the rear of the housing, and its middle section is rotatably hinged to the housing to adjust the elastic force provided by the elastic mechanism to the support arm mechanism. The support arm mechanism includes at least a main support arm, and is hinged to the housing via the main support arm for opening and closing. The damping mechanism includes a base and a damper, a slider, and a front-to-back adjustment member disposed within the base. One end of the damper is connected to the slider, and the front-to-back adjustment member drives the slider to move, causing the slider to move the damper axially. The other end of the damper extends out of the base and abuts against the lower swing end of the main support arm, providing damping for the support arm mechanism. This structure has some drawbacks:

[0003] 1. When the door is closed, the damper acts at the lower swing end of the main support arm. When using a lightweight cabinet door, the torque at the lower swing end is small and cannot counteract the force of the damper, resulting in the cabinet door not being airtight when closed.

[0004] 2. The buffer damper and the adjustment component used to adjust the buffer damper are integrated into one unit, resulting in a large space occupation for this mechanism;

[0005] Therefore, further improvements are necessary. Utility Model Content

[0006] The purpose of this invention is to provide a furniture flipping device with an optimized buffer adjustment structure, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A furniture flipping device with an optimized buffer adjustment structure includes a housing and a support arm mechanism, an elastic mechanism, and a buffer disposed on the housing. The housing is disposed on a furniture cabinet. The support arm mechanism is connected to the cabinet door and flips relative to the furniture cabinet. The elastic mechanism provides an elastic force to the support arm mechanism, causing the support arm mechanism to automatically flip open or close relative to the housing. The buffer provides a buffering force when the support arm mechanism flips and closes. The support arm mechanism is provided with a buffer adjustment assembly, which includes a base, an actuating element, and a rotating element. The two ends of the base are respectively connected to two pivot points of the support arm mechanism. The actuating element is movably disposed within the base and has an actuating portion extending outside the base. When the device flips and closes, the buffer applies a force to the actuating portion. The rotating element is rotatably disposed within the base and is drively connected to the actuating element so that the rotation of the rotating element drives the actuating element to move linearly.

[0009] Preferably, the support arm mechanism includes at least a front support arm, a middle support arm, and a rear support arm. The seat is fixed to the inside of the middle support arm. The front end of the middle support arm is pivotally connected to the front support arm, and the rear end is pivotally connected to the upper end of the rear support arm via a connecting rod. The upper end of the middle support arm is pivotally connected to the housing, the middle part of the rear support arm is pivotally connected to the housing, and the end of the rear support arm away from the connecting rod is pivotally connected to an elastic mechanism.

[0010] Preferably, the buffer further includes a fixed seat and a slider. The fixed seat is fixed inside the housing and has a receiving cavity for placing the buffer. The slider is disposed in the receiving cavity along a straight line. One end of the buffer acts on the fixed seat and the other end acts on the slider.

[0011] Preferably, a transmission element is provided between the fixed base and the base body, the middle part of the transmission element is rotatably connected to the housing, and the upper end of the transmission element abuts against the slider and the lower end abuts against the actuating part.

[0012] Preferably, the actuating part is provided with an arc-shaped chamfer, and the end of the slider is provided with a semi-circle.

[0013] Preferably, the actuating element is provided with a gear shift post, the base body is provided with a sliding groove corresponding to the gear shift post, the gear shift post and the sliding groove are slidably engaged, and the middle support arm is provided with an observation hole corresponding to the sliding groove.

[0014] Preferably, the rotating element includes a threaded portion and a rotating portion, the actuating element is provided with a first nut, the threaded portion is connected to the first nut, and the rotating portion is rotatably connected to the base.

[0015] Preferably, the system further includes a door opening angle adjustment mechanism, which includes an adjusting seat, a second nut, a limiting pin, and an adjusting screw. The support arm mechanism also includes a front swing arm and a rear swing arm. The front ends of the front swing arm and the front support arm are pivotally connected to the mounting element. The rear end of the front swing arm is pivotally connected to the front end of the rear swing arm. The adjusting seat is fixed inside the front swing arm. The second nut is disposed inside the adjusting seat. The limiting pin is fixed inside the front support arm. The adjusting screw is connected to the second nut so that the adjusting screw moves axially along the second nut when it rotates, and the end of the adjusting screw abuts against the limiting pin. The middle part of the rear swing arm is pivotally connected to the middle part of the front support arm, and the rear end of the rear swing arm is pivotally connected to the housing.

[0016] Compared with the prior art, this technical solution provides a furniture flipping device with an optimized buffer adjustment structure: by setting the buffer adjustment component and the buffer separately, and setting the buffer adjustment component on the two pivot points of the support arm mechanism, the buffer adjustment component is driven to flip and act on the buffer when the support arm mechanism flips. This structure not only makes reasonable use of the internal space of the flipping device, but also avoids the problem of the door not being able to close due to the small flipping torque at the point of action of the buffer by changing the point of action of the buffer.

[0037] A transmission element 60 is provided between the fixed base 41 and the base body 51. The middle part of the transmission element 60 is rotatably connected to the housing 10, and the upper end of the transmission element 60 abuts against the slider 42, and the lower end abuts against the actuating part 521.

[0038] The actuating part 521 is provided with an arc-shaped chamfer, and the end of the slider 42 is provided with a semi-circle.

[0039] The actuating element 52 is provided with a stop post 522, and the base 51 is provided with a sliding groove 511 corresponding to the stop post 522. The stop post 522 and the sliding groove 511 are slidably engaged. The middle support arm 22 is provided with an observation hole 221 corresponding to the sliding groove 511. The housing 10 is also provided with an observation hole. The position of the actuating element 52 can be viewed through the two observation holes when the flipping device is in the open state, and the position of the actuating element 52 can be adjusted according to the needs.

The adjusting seat 71 is fixed inside the front swing arm 25, the second nut 72 is located inside the adjusting seat 71, the limiting pin 73 is fixed inside the front support arm 21, and the adjusting screw 74 is connected to the second nut 72. The adjustment screw 74 is rotated so that it moves axially along the second nut 72, and the end of the adjustment screw 74 abuts against the limit pin 73. The middle part of the rear swing arm 26 is pivotally connected to the middle part of the front support arm 21, and the rear end of the rear swing arm 26 is pivotally connected to the housing 10. When the furniture flipping device is in the open state, the limit pin 73 abuts against the end of the adjustment screw 74, so that the opening angle is limited by the relative position of the adjustment screw 74. By rotating the adjustment screw 74, its relative position on the adjustment seat 71 is adjusted, thereby changing the contact point between the limit pin 73 and the adjustment screw 74, and thus adjusting the opening angle.
