[0021] The present invention is further described below in detail with reference to the accompanying drawings. A connector for a concealed corner cabinet is characterized by comprising a fixed base 1 and a movable base 2. A linear slider 4 is mounted on the fixed base 1 via a linear guide 3, and the linear slider 4 slides on the linear guide 3. The linear slider 4 is connected to the movable base 2 via a rotating shaft 5, and the movable base 2 can rotate about the rotating shaft 5. A track guide device is also provided between the movable base 2 and the fixed base 1, guiding the movable base 2 to rotate about the rotating shaft 5 and slide on the linear guide 3 via the linear slider 4.

[0022] The track guiding device is a track groove 6 provided on the movable seat 2 . Correspondingly, a guide wheel 7 is provided on the fixed seat 1 . The guide wheel 7 slides in the track groove 6 .

[0023] The track guiding device is a track groove 6 provided on the fixed seat 1 . Correspondingly, a guide wheel 7 is provided on the movable seat 2 . The guide wheel 7 slides in the track groove 6 .

[0024] The track of the track groove 6 is arranged in a "3" shape.

[0025] The guide wheel 7 is a rolling bearing.

[0026] The fixing seat 1 is further provided with a reset spring 8 , the other end of which is connected to the linear slider 4 , pulling the linear slider 4 to always move toward the closed end of the linear guide rail 3 .

[0027] The fixing seat 1 is also provided with a buffer damper 9, and the piston rod 10 of the buffer damper 9 extends into the closed end of the linear guide rail 3. When the linear slider 4 runs to the closed end, it contacts the piston rod 10 to produce a damping effect.

[0028] A connecting seat 11 is fixed on the linear slider 4 , and the left and right ends of the connecting seat 11 extend outward. The reset spring 8 or the piston rod 10 of the buffer damper 9 is connected to the connecting seat 11 .

[0029] The return tension spring 8 or the buffer damper 9 is distributed on both sides of the linear guide rail 3.

[0030] The rotating shaft 5 is connected to the movable seat 2 through a bearing.

[0031] Working principle: Figure 1-4 As shown, when the connector in this case is used with a corner cabinet 12, a set of connectors needs to be installed on both the upper and lower ends of the corner cabinet 12. The movable seat portion of the connector is fixed to the top and bottom plates of the corner cabinet 12, and the fixed seat portion of the connector is fixed to the cabinet body 13. By connecting the two sets of connectors, the corner cabinet can be rotatably installed on the cabinet body. When the user rotates the corner cabinet, the corner cabinet drives the movable seats at its upper and lower ends to move synchronously. When the movable seats move, they are squeezed by the track groove and the guide wheel, so that while the corner cabinet rotates around the rotating axis, it also slides on the linear guide rail through the linear slider. Through the mutual coordination of linear motion and rotational motion, when the corner cabinet rotates, its main body will translate outward through the linear guide rail, avoiding collision with the cabinet body 13 when the corner cabinet rotates. After the corner cabinet is rotated into place, the main body translates inward and rotates synchronously under the action of the track groove, finally achieving a 180° rotation of the corner cabinet 12. By rotating the corner cabinet 12, the user can realize the display state of the corner cabinet with the cabinet opening facing outward or the hidden state of the corner cabinet 12 with the cabinet opening facing inward. Therefore, the user can choose the display state with the cabinet opening facing outward or the hidden state with the cabinet opening facing inward according to their actual use needs, thereby playing the role of closing the cabinet body, while maintaining privacy, preventing dust accumulation in the corner cabinet and keeping the interior of the cabinet clean.

[0032] To ensure the corner cabinet remains in either an open or closed state, a return spring 8 is provided on the fixed base 1. The other end of the return spring 8 is connected to the linear slider 4, pulling the linear slider 4 toward the closed end of the linear guide rail 3. When the corner cabinet is opened or closed to a certain extent, the return spring pulls the linear slider toward the closed end. The guide rail deflects, automatically pulling the corner cabinet inward to close or open. The spring also maintains the corner cabinet in either a closed or open state, preventing it from rotating or shaking when not in use.

[0033] Furthermore: In order to avoid the tension spring from pulling too fast, causing collision between the corner cabinet and the cabinet body, the guide wheel and the end of the track groove to generate noise, or the items in the corner cabinet to fall over and move, a buffer damper 9 is also provided on the fixed seat 1 in this case. The piston rod 10 of the buffer damper 9 extends into the closed end of the linear guide rail 3. When the linear slider 4 runs to the closed end, it contacts the piston rod 10 to generate a damping effect. Under the action of the spring tension, the damper is pushed to close slowly, thereby slowing down the speed of the corner cabinet when it is reset, making the corner cabinet light and silent when opened and closed.

[0034] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the claims of the present invention.
