Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigerators, and in particular to a refrigerator flip beam and a refrigerator using the same. Background Technology
[0002] Refrigerators are essential household appliances. Current multi-door refrigerators typically employ a flip-up beam on one of the doors to prevent cold air loss through the gap between the two doors. As the doors open and close, the flip-up beam switches between an extended and retracted position. When extended, the beam seals the gap between the two doors. This is illustrated in the refrigerator with a flip-up beam disclosed in patent number CN111121928570.4. However, to ensure the flip-up beam cannot rotate when in the extended position, its internal structure is quite complex, with many parts, making it prone to damage. Utility Model Content
[0003] To address the aforementioned problems, the purpose of this utility model is to provide a refrigerator tilting beam with a simple structure and stable operation, and a refrigerator using the same beam.
[0004] The technical solution adopted by this utility model to solve the problem is: a refrigerator tilting beam, comprising:
[0005] A beam body, wherein an installation cavity is provided inside the beam body, and an opening communicating with the installation cavity is provided at the top of the beam body;
[0006] A push rod, comprising an upper drive section and a lower working section, wherein the working section is arranged in the mounting cavity and can be raised and lowered within the mounting cavity, the drive section extends along the opening to the top of the beam, and a stop is provided on the working section;
[0007] A hinge seat includes a fixed seat extending to the outside of the side of the beam and a rotating shaft pivotally connected to the mounting cavity. The outer periphery of the rotating shaft is provided with a first clearance area and a second clearance area. The second clearance area includes a lower notch section that is flush with the first clearance area in the vertical direction and an upper notch section that is higher than the first clearance area. The outer periphery of the rotating shaft forms a stop portion that is above the first clearance area and flush with the upper notch section. The first clearance area and the second clearance area are connected to each other on the side. The stop is located at the first clearance area or the second clearance area and can abut against the top of the first clearance area and the second clearance area.
[0008] A first reset spring is disposed on the mounting cavity and connected to the push rod, and the first reset spring is used to drive the push rod to move upward.
[0009] In the unlocked state, the push rod compresses the first return spring, thereby driving the stop to the lower part of the mounting cavity. The stop cooperates with the first clearance area and the lower notch section and can switch between the first clearance area and the lower notch section. In the locked state, the push rod moves upward to the higher part of the mounting cavity so that the distance from the drive section to the top of the beam reaches the maximum. The stop is located at the upper notch section, and the stop part abuts against the stop to restrict the rotation of the rotating shaft.
[0010] As a further improvement to the above technical solution, a second return spring connected to the rotating shaft is provided in the mounting cavity. The second return spring is used to drive the rotating shaft to return to the second clearance zone.
[0011] As a further improvement to the above technical solution, the top of the first air-avoidance zone forms an upwardly sloping guide slope from a position away from the second air-avoidance zone toward a position closer to the second air-avoidance zone.
[0012] As a further improvement to the above technical solution, the edges connecting the first and second air-avoidance zones form a smooth transition.
[0013] As a further improvement to the above technical solution, the edge of the first clearance zone and the edge of the second clearance zone are connected by a circular arc surface, with the center of rotation of the rotating shaft as the point of the arc surface.
[0014] As a further improvement to the above technical solution, a cavity extending through the front and back is provided in the middle of the working section, and an insertion platform is provided on the inner wall of the mounting cavity. The insertion platform is inserted into the cavity, one end of the first return spring abuts against the upper surface of the insertion platform, and the other end of the first return spring abuts against the top surface of the cavity.
[0015] As a further improvement to the above technical solution, both the insertion platform and the top surface of the cavity are provided with insertion posts that are inserted into the first return spring.
[0016] As a further improvement to the above technical solution, a connecting beam is provided laterally on the side of the bottom of the working section, and the stop is arranged at the end of the connecting beam.
[0017] A refrigerator includes a refrigerator body with two doors arranged on the refrigerator body, characterized in that: one of the doors is provided with any of the above-mentioned refrigerator flip beams, wherein a fixed base is fixed to the side of the refrigerator door, and a guide groove is provided on the top of the refrigerator body, the guide groove being used to press and guide the drive section to rotate.
[0018] The beneficial effects of this utility model are as follows: When the box door is closed, the drive section enters the guide groove at the top of the box body and is therefore pushed down by the guide groove, which guides the drive section to rotate the beam body into the unfolded position. The drive section is pushed down so that the push rod is located in the low position in the mounting cavity, which is in the unlocked state. The stop is located at the height of the first clearance zone and the lower notch section, so it can switch between the first clearance zone and the lower notch section. Therefore, when the box door is closed, the hinge seat can rotate smoothly relative to the beam body, so that the rotating shaft can rotate relative to the stop, thus allowing the stop to rotate from the lower notch section to the first clearance zone. When the door is opened, the drive section disengages from the guide groove and guides the beam to rotate relative to the door, thus entering the retracted position. At this time, the rotating shaft rotates, causing the stop to move from the first clearance area to the lower notch section. Since the first return spring drives the push rod to move upward, and there is also an upper notch section at the top of the lower notch section, the stop has space to move upward. The push rod moves upward as a whole until the distance from the drive section to the top of the beam reaches its maximum. At this time, the stop moves to the upper notch section. Since the upper part of the first clearance area has not been cut, a stop part is formed. When the rotating shaft rotates, the stop part will encroach on the space where the stop is located. Therefore, the stop part restricts the rotating shaft from rotating back by abutting against the stop part. Therefore, when the flip beam is in the retracted position relative to the door, the hinge seat is in the locked state. At this time, the hinge seat cannot rotate relative to the box, so the beam is always in the retracted position. Compared with the prior art, this solution has a simple structure, is easy to use, and has strong stability. Attached Figure Description

[0032] Reference Figures 1 to 8 A refrigerator tilting beam, comprising:
[0033] The beam body 10 has an installation cavity 11 inside, and the top of the beam body 10 has an opening that communicates with the installation cavity 11.
[0034] Push rod 20, the push rod 20 includes an upper drive section 21 and a lower working section 22, the working section 22 is arranged in the mounting cavity 11 and can be raised and lowered in the mounting cavity 11, the drive section 21 extends along the opening to the top of the beam 10, and a stop 23 is provided on the working section 22;
[0035] The hinge seat 30 includes a fixed seat 31 extending to the outside of the side of the beam 10 and a rotating shaft 32 pivotally connected to the mounting cavity 11. The outer periphery of the rotating shaft 32 is provided with a first clearance area 33 and a second clearance area 34. The second clearance area 34 includes a lower notch section 341 that is flush with the first clearance area 33 in the vertical direction and an upper notch section 342 that is higher than the first clearance area 33. The outer periphery of the rotating shaft 32 forms a stop part 35 that is above the first clearance area 33 and flush with the upper notch section 342. The first clearance area 33 and the second clearance area 34 are connected to each other. The stop member 23 is located at the first clearance area 33 or the second clearance area 34 and can abut against the top of the first clearance area 33 and the second clearance area 34.
[0036] A first reset spring 40 is disposed on the mounting cavity 11 and connected to the push rod 20. The first reset spring 40 is also used to drive the push rod 20 to move upward.
[0037] In the unlocked state, the push rod 20 presses the first return spring 40, thereby driving the stop 23 to the lower part of the mounting cavity 11. The stop 23 cooperates with the first clearance area 33 and the lower notch section 341 and can switch between the first clearance area 33 and the lower notch section 341. In the locked state, the push rod 20 moves upward to the higher part of the mounting cavity 11 so that the distance from the drive section 21 to the top of the beam 10 reaches the maximum. The stop 23 is located at the upper notch section 342, and the stop part 35 abuts against the stop 23 to restrict the rotation of the rotating shaft 32.
[0038] This utility model also discloses a refrigerator, including a refrigerator body with two doors 1 arranged on the refrigerator body. One of the doors 1 is provided with the above-mentioned refrigerator flip beam. The fixed seat 31 is fixed to the side of the refrigerator door 1. The top of the refrigerator body is provided with a guide groove. The guide groove is used to press and guide the drive section 21 to rotate. The guide groove is a conventional structure used in existing refrigerators to cooperate with the flip beam. Therefore, its specific structure and arrangement will not be described in this application.
[0039] When the door 1 is closed, the drive section 21 enters the guide groove at the top of the box and is thus pushed downward by the guide groove, which guides the drive section 21 to rotate the beam 10 into the unfolded position. The drive section 21 is pushed downward so that the push rod 20 is located in the low position in the mounting cavity 11, which is in the unlocked state. The stop 23 is located at the height of the first clearance zone 33 and the lower notch section 341, so it can switch between the first clearance zone 33 and the lower notch section 341. Therefore, when the door 1 is closed, the hinge seat 30 can rotate smoothly relative to the beam 10, so that the rotating shaft 32 can rotate relative to the stop 23. Thus, the stop 23 can rotate from the lower notch section 341 to the first clearance zone 33. When the door 1 is opened, the drive section 21 disengages from the guide groove and guides the beam 10 to rotate relative to the door 1, thus entering the retracted position. At this time, the rotating shaft 32 rotates, causing the stop 23 to move relative to the first clearance area 33 into the lower notch section 341. Since the first return spring 40 drives the push rod 20 to move upward, and there is also an upper notch section 342 at the upper end of the lower notch section 341, space is provided for the stop 23 to move upward. The push rod 20 moves upward as a whole until the distance from the drive section 21 to the top of the beam 10 reaches its maximum. At this time, the stop 23 moves to the upper notch section 341. At the notch section 342, and since the upper part of the first clearance zone 33 has not been cut out, a stop part 35 is formed. When the rotating shaft 32 rotates, the stop part 35 will infringe on the spatial position of the stop member 23. Therefore, the stop member 23 restricts the rotating shaft 32 from rotating back by abutting against the stop part 35. So when the flip beam is in the retracted position relative to the box door 1, the hinge seat 30 is in the locked state. At this time, the hinge seat 30 cannot rotate relative to the box body, so the beam 10 is always in the retracted position. Compared with the prior art, this solution has a simple structure, is easy to use, and has strong stability.
[0040] To further optimize the design and minimize the conflict between the push rod 20 and the hinge seat 30, a connecting beam 231 is preferably provided laterally on the side of the bottom of the working section 22, with the stop 23 located at the end of the connecting beam 231. In other embodiments, the stop 23 can also be located directly below the working section 22 or on the front end face of the working section 22, but this arrangement would result in an excessively thick beam 10.
[0041] Further optimization is preferred, where a second return spring 50 connected to the rotating shaft 32 is provided in the mounting cavity 11. The second return spring 50 is used to drive the rotating shaft 32 to return to the second clearance zone 34, so that after the cabinet door 1 is opened relative to the refrigerator, the second return spring 50 can actively drive the flip beam to rotate toward the retracted position. Under this structure, even if a person or object accidentally touches the drive section 21 and presses down the push rod 20, as long as it cannot enter the guide groove to guide the beam 10 to rotate or be manually driven to rotate the beam 10, even if the push rod 20 is pressed down, the rotating shaft 32 will not rotate toward the first clearance zone 33, so that the stop 23 is always in the second clearance zone 34 to keep the flip beam in the retracted position.
[0042] To further optimize the process, and to ensure a smoother relative movement of the stop 23 from the first clearance zone 33 to the second clearance zone 34 during the rotation of the rotating shaft 32, minimizing impact, it is preferable that the top of the first clearance zone 33 forms an upwardly sloping guide surface 331, moving from a position away from the second clearance zone 34 towards a position closer to it. Similarly, it is preferable that the edges connecting the first clearance zone 33 and the second clearance zone 34 form a smooth transition, both for smoother rotation and to prevent the sharp edges formed at the junction of the first clearance zone 33 and the second clearance zone 34 from jamming with the stop 23. Furthermore, it is preferable that the edges of the first clearance zone 33 and the second clearance zone 34 are connected by a circular arc surface 36, with the rotation axis of the rotating shaft 32 as its center.
[0043] Under other dimensional designs, the included angle between the inner end faces of the first clearance zone 33 and the second clearance zone 34 can have different values, as long as the two extreme points where the first clearance zone 33 and the second clearance zone 34 restrict the rotation of the stop 23 respectively allow the beam 10 to rotate at exactly 90 degrees. Alternatively, depending on the refrigerator design, the rotation of the beam 10 can reach a specified value, such as 80 degrees or 111 degrees.
[0044] In this design, the first return spring 40 can abut against any position on the working section 22. However, to ensure stability, it is preferable that a cavity 24 extending through the front and back is provided in the middle of the working section 22. A insertion platform 12 is provided on the inner wall of the mounting cavity 11, and the insertion platform 12 is inserted into the cavity 24. One end of the first return spring 40 abuts against the upper surface of the insertion platform 12, and the other end of the first return spring 40 abuts against the top surface of the cavity 24. Furthermore, it is preferable that both the insertion platform 12 and the top surface of the cavity 24 are provided with insertion posts 25 inserted into the first return spring 40 to ensure the fixation of the first return spring 40. Preferably, the width of the insertion platform 12 is the same as the width of the cavity 24.
[0045] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
