Description

A damping buffer structure for a furniture flip-up device

Technical Field

The utility model relates to the technical field of cabinet door accessories, in particular to a damping buffer structure of a furniture flip-up device.

Background Art

At present, many cabinet doors use upward flip door hinges to achieve the upward flip opening function. The upward flip door hinges provide original power through spring components. The magnitude of the force effect is achieved by adjusting the position of the spring component to achieve the length of the force arm. The direction of the force and the closing and opening of the door panel are achieved through the direction of the connecting rod assembly connected to the force arm.

One end of the damper 502 is connected to the slider 503. The seat body 501 is installed in the housing 10 below the force adjustment mechanism 30. The front and rear adjustment member 504 drives the slider 503 to move, so that the slider 503 drives the damper 502 to move in the axial direction. The other end of the damper 502 extends out of the seat body 501 and abuts against the lower swing end of the main support arm 201, so that the damper 502 provides damping for the support arm mechanism 20.

As mentioned above, a damping mechanism 50 is separately arranged on the housing 10 of the furniture flipping device, and a damper 502, a slider 503 and a front-rear adjustment member 504 are arranged in the seat 501 of the damping mechanism 50. One end of the damper 502 extends out of the seat 501 and abuts against the lower swing end of the main support arm 201, so that the damper 502 abuts against the main support arm 201 and provides a damping effect when the flipping device is in a closed state, thereby providing a damping effect for the support arm mechanism 20;

In addition, the slider 503 is driven to move by the front and rear adjusting members 504, and the slider 503 drives the damper 502 to move in the axial direction, so that the damper 502 can adjust the relative position of the flip device and the door body through the front and rear adjusting members 504.

The buffer arm 202 is a hollow structure, and a plurality of reinforcing ribs 2022 are staggeredly distributed on the inner side. The buffer arm 202 replaces the main support arm 201 as the force-bearing part. After the upper flip door device completes the closing work, the positioning portion 2022 cooperates with the damper 502 to position it, thereby ensuring the stability of the upper flip door device after closing.

Specifically, a movable groove 5011 is opened on the seat body 501, and the front end of the movable groove 5011 passes through the seat body 501 to form an opening, the damper 502 is arranged in the movable groove 5011, and extends out of the seat body 501 from the opening, and the end of the damper 502 extending out of the seat body 501 is connected with a support member 505, and a buffer pad 506 is arranged on the end of the support member 505 away from the damper 502, and the end face of the buffer pad 506 is an arc structure, and the buffer pad 506 abuts against the buffer arm 202 when the support arm mechanism 20 is closed to the buffer state, and the buffer pad 506 is used to increase the contact area between the buffer arm 202 and the buffer pad 506, reduce the occurrence of abnormal noise due to contact, and make the door support mechanism quiet and smooth during the opening and closing process.

Specifically, a sliding groove 5012 is provided at a position of the seat body 501 located at the rear end of the movable groove 5011, and the slider 503 moves in the sliding groove 5012 and the movable groove 5011 along the length direction of the sliding groove 5012. A receiving groove 5013 is provided at a position of the seat body 501 located on one side of the movable groove 5011. The rear end of the receiving groove 5013 passes through the sliding groove 5012, and the front end passes through the seat body 501. The front and rear adjustment member 504 is rotatably arranged in the receiving groove 5013. The front and rear adjustment member 504 at least includes a driving part 5041 at the front end and an external threaded part 5042 located at the rear end. The external threaded part 5042 extends to the sliding groove 5012 and is threadedly connected to the slider 503. When adjusting the damping force, a tool is inserted into the front end of the receiving groove 5013 to rotate the front and rear adjustment member 504, so that the slider 503 moves in the sliding groove 5012 and the movable groove 5011, thereby driving the damper 502 to move forward and backward.

Specifically, the support arm mechanism 20 also includes an outer arm 203, a front link 204, a rear link 205 and a swing arm assembly 206.
