Description

Technical Field

[0001] This invention relates to the field of refrigerator technology, and more specifically, to a refrigerator door locking mechanism. Background Technology

[0002] Traditional refrigerators, such as Figure 7 As shown, a locking seat is fixedly installed at the bottom of the refrigerator door, and a locking head 18 is integrally formed on the locking seat. A hinge seat is fixedly installed on the cabinet, and a locking arm 17 is integrally formed on the hinge seat. The locking seat and the hinge seat are rotatably connected to each other. When the refrigerator door is closed, the locking arm 17 presses against the locking head 18, achieving the purpose of locking. The above structure has two problems during use: first, the locking force gradually decreases with the increase of the number of times the door is opened and closed; second, the locking force generated by the locking arm 17 pressing against the locking head 18 cannot be freely adjusted.

[0003] Therefore, it is necessary to improve the existing technology. Summary of the Invention

[0004] The purpose of this invention is to provide a refrigerator door locking mechanism, aiming to solve at least one of the technical problems existing in the prior art. To achieve the above objective, the technical solution adopted is as follows:

[0005] A refrigerator door locking mechanism includes a locking seat, a connecting member, a connecting rod, and a locking block. The connecting member includes a connecting member body, with a first arm fixed at one end and a second arm fixed at the other end. The connecting member body is rotatably connected to the locking seat. A first locking bolt can fix the first arm and the locking seat together to prevent the rotation of the connecting member. The locking block includes a locking block body, with a third arm fixed at one end and a clamping elbow fixed at the other end. The locking block body is rotatably connected to the second arm. The connecting rod is rotatably mounted on the locking seat. A second locking bolt and a nut can fix the third arm and the connecting rod together to prevent the rotation of the locking block.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] like Figures 1 to 2 As shown, a preferred embodiment of the present invention provides a refrigerator door locking mechanism, which includes a locking seat 1, a connecting member 2, a connecting rod 3, a locking block 4, and a locking spring 5.

[0029] like Figure 3 As shown, the locking seat 1 is fixedly installed at the bottom of the door body, and a rotating shaft (not shown in the figure) is vertically fixed on the locking seat 1 near the inside of the refrigerator.

[0030] like Figure 4 As shown, the connector 2 includes a connector body 6. One end of the connector body 6 is fixedly provided with a first arm 7, and the other end is fixedly provided with a second arm 8. The connector body 6, the first arm 7, and the second arm 8 are an integral structure to enhance the overall strength. The connector body 6 is provided with a shaft hole, through which the connector body 6 is rotatably mounted on a rotating shaft. The first arm 7 is provided with an arc-shaped elongated through hole 9, the center of which is located on the axis of the rotating shaft. When the connector 2 is rotated to a suitable angle, a first locking bolt passes through the arc-shaped elongated through hole 9 and is threadedly connected to the locking seat 1 to lock the rotation of the connector 2.

[0031] Furthermore, a number of sequentially connected first enlarged holes 19 are provided on the inner wall of the arc-shaped long through hole 9 along the length direction of the arc-shaped long through hole 9. Each first enlarged hole 19 is adapted to the first locking bolt. The purpose is to limit the first locking bolt and prevent the first locking bolt from loosening and displacing.

[0032] like Figure 5 As shown, the locking block 4 includes a locking block body 10. A third arm 11 is fixedly mounted at one end of the locking block body 10, and a clamping elbow 12 is fixedly mounted at the other end. The locking block body 10, the third arm 11, and the clamping elbow 12 are an integral structure to enhance the overall strength. The locking block body 10 is rotatably connected to the second arm 8. The third arm 11 is provided with a first elongated through hole 13 that passes through the third arm 11 horizontally and a second elongated through hole 14 that passes through the third arm 11 vertically.

[0033] like Figure 6 As shown, the connecting rod 3 is rotatably mounted on the rotating shaft. The connecting rod 3 is provided with a third long through hole 15. The connecting rod 3 passes through the first long through hole 13 and can slide along the length direction of the first long through hole 13. When the locking block 4 is rotated to a suitable angle, the second locking bolt passes through the second long through hole 14 and the third long through hole 15 and is tightened with a nut to lock the rotation of the locking block 4.

[0034] Furthermore, the inner walls of the second through hole 14 and the third through hole 15 are respectively provided with a number of sequentially connected second enlarged holes 20. Each second enlarged hole 20 is adapted to the second locking bolt. The purpose is to limit the second locking bolt and prevent the first locking bolt from loosening and displacing.

[0035] One end of the locking spring 5 is connected to the clamping elbow 12, and the other end is connected to the main body of the connector 6, ensuring that the locking spring 5 is in a stretched state.

[0036] The hinge seat 16 is fixedly installed on the cabinet body. The locking seat 1 is rotatably connected to the hinge seat 16. The locking arm 17 is fixed on the hinge seat 16. When the door is closed, the locking arm 17 squeezes and locks the elbow 12, thus locking it.

[0037] Rotating the connecting piece 2 synchronously drives the locking block 4 to rotate, thereby adjusting the angle of the clamping elbow 12 in the horizontal direction, adjusting the position of the clamping arm 17 pressing the clamping elbow 12, and ultimately adjusting the locking force. Rotating the locking block 4 can also adjust the angle of the clamping elbow 12 in the horizontal direction, and ultimately adjust the locking force. In addition, it can also adjust the tension of the locking spring 5. When the door is closed, the clamping arm 17 presses the clamping elbow 12. At this time, the clamping force on the clamping elbow 12 is the same as the tension of the locking spring 5. When the door is opened, the clamping force on the clamping elbow 12 is opposite to the tension of the locking spring 5. At this time, the locking spring 5 protects the clamping elbow 12 and prevents irreversible deformation of the clamping elbow 12.

[0038] In summary, the refrigerator door locking mechanism described in this embodiment of the invention allows for free adjustment of the door's locking force, while also preventing irreversible deformation of the locking bend. Furthermore, the mechanism has a simple structure, low manufacturing cost, and provides a good user experience.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
