AI Technical Summary
The existing refrigerator door hinge structure lacks a buffering mechanism, which leads to excessive force closing of refrigerator doors when artificially closing them, the door may be quickly closed due to inertia, causing noise and may damage the refrigerator door or body, shortening the service life of the refrigerator.
A suspended fixed hinge structure is designed. By setting a buffer member in the rotating mechanism, the impact force of the door is cushioned when the door is closed, so as to stabilize the door closure, reduce noise and avoid damage caused by excessive force in the refrigerator.
Through the action of the buffer, the closing speed of the refrigerator door is stabilized and controlled, the noise and impact force are reduced, and the service life of the refrigerator is extended.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0021] Refer to Figures 1-7, A floating fixed hinge structure, including a refrigerator. There are two sealed doors at the front end of the refrigerator. Two rotating mechanisms are installed between each sealed door and the refrigerator, and the opening and closing of the sealed doors are realized through the rotating mechanisms.
[0022] The rotating mechanism includes a first mounting plate, a fixed block, a rotating block, a first deflection block, a second deflection block, a connecting block, and a second mounting plate. The first mounting plate is fixedly connected to the refrigerator, and the refrigerator and the first mounting plate are installed and fixed by bolts. There is a groove on the sealed door, and the second mounting plate is located in the groove and fixedly connected to its inner wall. The second mounting plate and the sealed door are installed and fixed by bolts.
[0023] The first mounting plate is fixedly connected to the fixed block. The fixed block is rotatably connected to the rotating block, and a first rotating shaft is rotatably connected between the fixed block and the rotating block. The rotating block is rotatably connected to the first deflection block and the second deflection block. A second rotating shaft is rotatably connected between the rotating block and the second deflection block, and a third rotating shaft is rotatably connected between the rotating block and the first deflection block. Both the first deflection block and the second deflection block are rotatably connected to the connecting block. A fourth rotating shaft is rotatably connected between the first deflection block and the connecting block, and a fifth rotating shaft is rotatably connected between the second deflection block and the connecting block. The connecting block is fixedly connected to the second mounting plate. The rotation of the connecting block is realized through the quadrilateral structure formed by the rotating block, the first deflection block, the second deflection block, and the connecting block, and the sealed door is opened and closed.
[0024] The second rotating shaft is connected to a buffer. The other end of the buffer is connected to the first deflection block. The buffer is a damping buffer, which is responsible for buffering the impact force generated when the refrigerator door is closed. It mainly controls the closing speed of the refrigerator door through the buffering effect of the damper, so that the door can close slowly when facing the impact force. This can effectively reduce the shaking of the items in the refrigerator or the situation of being damaged due to excessive force. The damping buffer is a prior art and will not be elaborated here.
[0025] The present utility model solves the problem in the prior art that when a person gives a relatively large force to close the refrigerator door subconsciously or accidentally, the refrigerator door often closes quickly due to inertia, which not only generates noise but also may cause damage to the refrigerator door or the refrigerator body, reducing the service life of the refrigerator, by setting the buffer.
