Embodiment 1

[0056] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0057] Such as figure 2 Shown is the internal structure schematic diagram of the flip beam structure used for refrigerator door sealing of the present invention, including shell 1, inner chamber 2, crank double slider mechanism 3, first button 4, spring mechanism 11; wherein crank double slider mechanism consists of Composed of shaft 6, disk 8, second connecting rod 9, first connecting rod 8, first slider 5 and first button 4; the shaft is fixed on the inner cavity wall of the flip beam, and the disk is sleeved on the shaft and can rotate , one end of the second connecting rod 9 and the first connecting rod 8 are connected with the disc through the rotating pair 14, the other end of the second connecting rod 9 is connected with the fi...

Embodiment 2

[0065] Such as Figure 5 As shown, similar to the basic principle of embodiment 1, embodiment 2 retains the shell 1, inner cavity 2, first button 4, first slider 5, roller 12, chute 11, and buffer gasket 13 of embodiment 1. , cancel the crank double slider mechanism 3; use the new second button 18, new slider 19 to form a wedge mechanism to replace the crank double slider mechanism 3 in embodiment 1, and increase the second spring 20, the second Three springs 21, the fourth spring 22, wherein one end of the second spring 20 is fixed on the wall of the inner chamber 2, and the other end is connected with the second button 18, and one end of the third spring 21 and the fourth spring 22 are fixed on both sides of the slide block 19. The other end is fixed on the beam 23 of the inner chamber 2.

[0066] The specific working process is as follows: when the right door of the refrigerator is closed and the second button 18 is pressed, the second button 18 moves toward the inner cavi...

Embodiment 3

[0068] Such as Figure 6-7 As shown, similar to the principles of Embodiments 1 and 2, Embodiment 3 retains the shell 1, inner cavity 2, first slider 5, roller 12, chute 11, and buffer gasket 13 of Embodiment 1, and cancels the crank Double slider mechanism 3, cancel the first button 4, cancel the spring mechanism 10; embodiment 3 retains the third spring 21, the fourth spring 22, the beam 23 of embodiment 2, embodiment 3 is in embodiment 1, 2 On the basis of the first slider 5 / 19, a bar-shaped first magnet 24 is embedded to form a new slider 25, while embodiment 3 also needs to embed the same bar-shaped magnet on the side where the right door of the refrigerator is in contact with the flip beam. The second magnet 26, the relative position of two magnets is as Figure 7 As shown, and the adjacent magnetic poles of the two magnets have the same name as the magnetic poles.

[0069] Such as Figure 8 As shown, the schematic diagram of force analysis of two magnets under the cl...

Abstract

The invention discloses an overturning beam structure for sealing a refrigerator door and a refrigerator. The overturning beam structure comprises a shell, an inner cavity, a sliding block and a driving mechanism. The shell is arranged on the first door body, the sliding block is arranged in the inner cavity, the driving mechanism is arranged on the shell, and the driving mechanism drives the sliding block to move between the bottom of the overturning beam and a refrigerator inner container; when the second door body exerts force on the driving mechanism on the shell, the driving mechanism drives the sliding block to move downwards to make contact with the inner container of the refrigerator, and the gap of the refrigerator is sealed. And when the second door body is opened, the force applied by the driving mechanism is eliminated, and the sliding block in the inner cavity moves upwards. According to the overturning beam structure for sealing the refrigerator door, on the basis that the refrigerator body is not changed, the sealing performance of the refrigerator in the door closing state is better, cold air leakage is reduced, and the energy-saving performance of the refrigerator is improved.

Description

technical field [0001] The invention relates to the field of household electrical appliances, in particular to a flip beam structure used for sealing a refrigerator door and a refrigerator. Background technique [0002] Refrigerator is a kind of frequently used household appliance, and along with the development of social economy, almost every household has purchased refrigerator, and side-by-side refrigerator is favored by people because of its beautiful appearance, large capacity, and many functions. At present, the common side-by-side refrigerators in daily life are divided into cold room, variable temperature room and freezer room from top to bottom. The cold room is generally equipped with left and right doors. A flip beam is hinged on the left door of the refrigerator. There is a guide body on the top of the flip beam, and a guide groove is set on the upper edge of the refrigerator liner. Generally, the left door of the refrigerator is closed first, and then the guide ...
