Description

Technical Field

[0001] The utility model relates to the field of refrigerator components, in particular to a refrigerator turnover beam structure. Background Art

[0002] The refrigerator flip beam is a structure on the refrigerator door, which is mainly used in the design of double-door or multi-door refrigerators. Its main function is to ensure that the door body and the refrigerator body can fit tightly during the opening and closing process.

[0003] The publication number is CN107024069B, which provides a double-door refrigerator with a flip beam, including a box body, two door bodies are arranged side by side on the box body, one of the door bodies is hinged with a flip beam, and a self-locking mechanism is provided between the flip beam and the door body. The self-locking mechanism includes a trigger rod, a locking ring and a locking shaft, and the trigger rod is slidably connected to the flip beam in the vertical direction.

[0004] The above-mentioned flip beam has the effect of improving the effectiveness and reliability of the locking between the flip beam and the door body. After the refrigerator door is closed, the flip beam body is prone to self-rotation and loosening, resulting in poor internal sealing, which is not convenient for automatic fixation after closing. After the refrigerator door is opened, the flip beam body needs to be manually operated, which is not convenient for automatic rotation to be perpendicular to the refrigerator door.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] Combine Figures 1-4 A refrigerator flip beam structure includes a flip beam body 1 and two fixed plates 2. The two fixed plates 2 are movably installed at the rear of the flip beam body 1. The two fixed plates 2 are used to be fixed on the refrigerator door body. A hinge shaft 3 is installed between the fixed plate 2 and the flip beam body 1. A fixing component 4 is installed inside the flip beam body 1, and a flip component 5 is installed inside the hinge shaft 3.

[0025] See Figure 2 and Figure 4 , it is further obtained that the fixed assembly 4 includes a slider 6 and a guide block 11, the slider 6 is movably installed inside the flip beam body 1, the top of the slider 6 is provided with a slope 7, a first spring 8 is connected between the front end of the slider 6 and the inner wall of the flip beam body 1, the rear end of the slider 6 is fixedly installed with a pressure block 9, the guide block 11 is movably installed on the top of the flip beam body 1, and a telescopic groove 12 is provided inside the large flip beam body 1, a guide rod 13 is installed at the bottom of the guide block 11 and passes through the telescopic groove 12, the outer periphery of the guide rod 13 is sleeved with a second spring 14, and the bottom end of the guide rod 13 is fixedly installed with a push block 15.

[0026] The slider 6 is located inside the flip beam body 1 and is arranged to slide back and forth. The front and rear ends of the first spring 8 are respectively connected to the inner wall of the flip beam body 1 and the front end of the slider 6.

[0027] A plurality of friction grooves 10 are formed on the periphery of the hinge shaft 3 , and the rear portion of the pressing block 9 matches the friction grooves 10 .

[0028] The guide rod 13 is located in the telescopic slot 12 and is slidable up and down. The bottom of the push block 15 is provided with opposite inclined surfaces 7.

[0029] Specifically, when the refrigerator door is closed, the guide block 11 enters the guide seat through the inclined chamfered surface and slides downward under the action of pressure, so that the guide rod 13 drives the push block 15 to slide downward, and through the push block 15 and the inclined surface 7 of the slider 6, the slider 6 drives the pressure block 9 to slide backward and contact the friction groove 10 of the hinge shaft 3, thereby increasing the friction force of the hinge shaft 3, and the flip beam body 1 is flipped to a parallel state through the guide seat. The friction force of the pressure block 9 prevents the flip beam body 1 from rotating and disengaging, thereby improving the internal sealing. The first spring 8 is used to pull the slider 6 to slide forward.

[0030] Example 2

[0031] See Figure 3 and Figure 4 , and on the basis of Example 1, it is further obtained that the flip assembly 5 includes four fixed shafts 16, which are respectively located at the upper and lower ends of the two hinge shafts 3, and a clamping column 17 is installed on the opposite side of the two adjacent fixed shafts 16 and passes through the interior of the hinge shaft 3. The clamping column 17 and the fixed shaft 16 are fixed to each other, and the clamping column 17 is located in the hinge shaft 3 and is movably connected. A connecting rod 18 is installed inside the hinge shaft 3 and passes through the two fixed shafts 16. A transmission groove 19 is opened inside the fixed shaft 16, and a third spring 20 is installed inside the transmission groove 19.

[0032] The fixed shaft 16 and the flip beam body 1 are fixedly installed, and both ends of the connecting rod 18 pass through the interior of the two fixed shafts 16 and are movably rotatable.

[0033] The two ends of the third spring 20 are fixedly connected to the connecting rod 18 and the inner wall of the transmission groove 19 respectively, and the connecting rod 18 and the hinge shaft 3 are fixed to each other.

[0034] Specifically, after the refrigerator door is opened, the guide block 11 disengages from the guide seat, causing the pressure block 9 to disengage from the friction groove 10, and under the action of the third spring 20, the connecting rod 18 is driven to rotate. Since the connecting rod 18 is fixed to the hinge shaft 3, the flip beam body 1 is rotated to be perpendicular to the fixed plate 2. Through the rotation of the flip beam body 1, the flip beam body 1 can be pulled after the refrigerator door is opened, and the flip beam body 1 is automatically perpendicular to the refrigerator door, preventing the flip beam body 1 from being accidentally touched and causing damage to the hinge shaft 3 after being vertically fixed.

[0035] During actual operation, the fixing plate 2 is installed on the refrigerator door, and the guide block 11 drives the flip beam body 1 to flip through the guide seat to perform sealing;

[0036] When the refrigerator door is closed and fixed, the guide block 11 slides downward through the guide seat, causing the guide rod 13 to drive the push block 15 to slide downward, and the slider 6 slides backward through the inclined surface 7. When the flip beam body 1 is flipped to be parallel to the refrigerator door, the interior is sealed, and the pressure block 9 contacts the friction groove 10, increasing the friction force of the hinge shaft 3, thereby fixing the flip beam body 1 to the refrigerator door. When opening again, the guide block 11 is separated from the guide seat and slides upward under the action of the second spring 14. The slider 6 slides forward under the action of the first spring 8, causing the pressure block 9 to be separated from the hinge shaft 3, causing the flip beam body 1 to flip;

[0037] When the flip beam body 1 is automatically made perpendicular to the refrigerator door, the connecting rod 18 is rotated under the action of the third spring 20. Since the connecting rod 18 is fixedly connected to the hinge shaft 3, the flip beam body 1 is rotated to be perpendicular to the refrigerator door. Through the connection between the fixed shaft 16 and the hinge shaft 3, the flip beam body 1 can automatically be perpendicular to the refrigerator door while rotating due to accidental touch.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
