Description

Technical field:

[0001] The present invention relates to a turnover beam structure and a refrigerator with the turnover beam structure, and belongs to the technical field of household appliances. Background technology:

[0002] The flip beam currently used in cross-door refrigerators sometimes requires manual reset when the door is open. Without this reset, the door cannot close properly. Furthermore, when the door is closed, the excessive outward force can cause the refrigerator to leak cold air.

[0003] Therefore, it is necessary to improve the existing technology to solve the shortcomings of the existing technology. Summary of the invention:

[0004] The present invention aims to solve the problems existing in the above-mentioned prior art and provides a flip beam structure and a refrigerator with the flip beam structure. When closing the door, the flip beam will be in a state perpendicular to the door body, so the door can be closed directly without manual resetting.

[0005] The present invention adopts the following technical solution: a flip beam structure, comprising a housing, an upper shaft of the flip beam disposed in the housing and fixed to the refrigerator door, a guide connecting rod movably fixed in the housing, and a guide block disposed on the upper side of the guide connecting rod;

[0006] The upper shaft of the flip beam is provided with a stopper protruding in the radial direction, the upper surface of the upper shaft of the flip beam is provided with a first meshing portion protruding, and a rotating shaft is formed at the center of the first meshing portion;

[0007] A turning beam suction aid is installed above the turning beam upper shaft, and the turning beam suction aid is sleeved on the outer side of the rotating shaft.

[0008] Furthermore, a first arc-shaped notch is formed on the first engaging portion, and a second arc-shaped notch is formed on the lower surface of the flip beam suction aid.

[0009] Furthermore, a first stopper is formed in a protrusion on the rear inner wall surface of the shell.

[0010] Furthermore, the guide connecting rod includes a rotation-stopping arm, a connecting arm, and a receiving portion formed on the connecting arm and located above the first stopper, and a first spring is installed between the receiving portion and the first stopper.

[0011] Furthermore, the upper axis of the flip beam includes a fixing portion fixed to the refrigerator door body and a connecting portion connected to the fixing portion, and the stop portion and the first engaging portion are both formed on the connecting portion.

[0012] Furthermore, a second spring is sleeved on the rotating shaft.

[0013] Furthermore, a second stopper is formed on the inner wall of the shell and above the second spring. The upper end of the second spring abuts against the second stopper, and the lower end abuts against the inner surface of the flip beam suction aid.

[0014] Furthermore, a through hole is formed on the upper surface of the shell and passes through the shell from top to bottom, and the guide block slides in the through hole.

[0015] Furthermore, the upper end of the guide block is configured as a smooth arc surface.

[0016] The present invention also adopts the following technical solution: a refrigerator includes a turning beam structure.

[0017] The present invention has the following beneficial effects: the flip beam structure of the present invention always remains perpendicular to the box body, so that the flip beam can be opened and closed at will without manual adjustment. At the same time, it also solves the risk of cold leakage when the door is closed. Description of the drawings:

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] The flip beam structure of the present invention includes a shell 1, a flip beam upper shaft 7 arranged in the shell 1 and fixed to the refrigerator door body, a guide connecting rod 3 movably fixed in the shell 1, and a guide block 2 arranged on the upper side of the guide connecting rod 3.

[0024] The upper surface of the housing 1 includes a vertically extending through-hole through which the guide block 2 slides. A first stopper 11 is formed as a protrusion on the rear inner wall of the housing 1. The guide connecting rod 3 includes a rotation-stopping arm 30, a connecting arm 31, and a receiving portion 32 formed on the connecting arm 31 and positioned above the first stopper 11. A first spring 4 is mounted between the receiving portion 32 and the first stopper 11.

[0025] The upper shaft 7 of the tilt beam includes a fixed portion 70 fixed to the refrigerator door and a connecting portion 71 connected to the fixed portion 70. The connecting portion 71 is cylindrical, and the housing 1 and the connecting portion 71 are mutually connected and can rotate relative to the connecting portion 71. The connecting portion 71 has a radially protruding stop portion 72. The upper surface of the connecting portion 71 has a first meshing portion 73 protruding therefrom, and a first arc-shaped notch 73 is formed in the first meshing portion 73.

[0026] A rotating shaft 74 is formed at the center of the first engaging portion 73 , and the second spring 5 is sleeved on the rotating shaft 74 .

[0027] The guide block 2 is fixed to the upper side of the connecting arm 31, and the upper end of the guide block 2 is set in a smooth arc surface. When the door is opened or closed, the upper end of the guide block 2 slides along the guide groove (not shown) opened on the refrigerator body.

[0028] The flip beam suction aid 6 is located above the flip beam upper shaft 7. The flip beam suction aid 6 is a hollow cylindrical structure. The flip beam suction aid 6 is sleeved on the outside of the rotating shaft 74. A second arc-shaped notch 60 is formed on the lower surface of the flip beam suction aid 6.

[0029] A second stopper 12 is formed on the inner wall of the housing 1 above the second spring 5 . The upper end of the second spring 5 abuts against the second stopper 12 , and the lower end abuts against the inner surface of the flip beam suction aid 6 .

[0030] The working principle of the flip beam structure including the shell of the present invention is as follows:

[0031] When the door is closed, guide block 2 slides along the guide groove defined in the refrigerator body. The lowest point of the arcuate surface of the guide block's upper end surface enters the guide groove before the highest point. As guide block 2 slides in the guide groove, the guide groove compresses guide block 2 downward. Guide connecting rod 3, elastically deformed by first spring 4, moves downward, causing guide connecting rod 3 to move to the position of stop 72, thereby locking and limiting the position of flip beam upper shaft 7. After the refrigerator door is closed, guide connecting rod 3 presses against flip beam upper shaft 7, preventing it from rebounding and thus achieving a sealing effect.

[0032] When the door is open, the guide block 2 slides along the guide groove provided on the box body. The highest point of the arc surface of the upper end face of the guide block leaves the guide groove before the lowest point. As the guide block 2 slides in the guide groove, the guide connecting rod 3 is elastically deformed and rebounded by the first spring 4. The guide connecting rod 3 is disengaged from the upper shaft 7 of the flip beam. The flip beam suction aid 6 slides down along the arc curve of the upper shaft 7 of the flip beam. The second spring 5 resets freely. In the open door state, when the upper shaft 7 of the flip beam is not limited, the flip beam structure itself and the box body always remain vertical, so that the flip beam can be opened and closed at will without manual adjustment. This also solves the risk of cold leakage when the door is closed.

[0033] The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as the scope of protection of the present invention.
