Specifically, when the first door body 2 is opened, the turnover beam 3 can rotate to the back side of the first door body 2 under the action of the reset member until the turnover beam 3 is attached to the side wall of the door liner 22. If the side wall of the door liner 22 is relatively perpendicular to the back surface of the first door body 2, the turnover beam 3 is relatively perpendicular to the back surface of the first door body 2. If the side wall of the door liner 22 is approximately perpendicular to the back surface of the first door body 2, the turnover beam 3 is approximately perpendicular to the back surface of the first door body 2 at this time, that is, the included angle between the turnover beam 3 and the back surface of the first door body 2 is slightly larger or slightly smaller than 90 °. Therefore, when the first door body 2 is opened, the turnover beam 3 can automatically rotate towards the back side direction of the first door body 2 under the driving of the reset piece, and when the first door body 2 is closed, the matching groove 31 can face the back side of the door body 2, face the first end of the guide chute 51 and face the sliding column 6, the matching groove 31 can precisely abut against the sliding column 6, and further the sliding column 6 is pushed to move towards the second end of the guide chute 51, so that the turnover beam 3 can be effectively ensured to be unfolded smoothly, and the first door body 2 and the turnover beam 3 can be normally and smoothly attached to the front side wall of the box body 1.

In some embodiments, the restoring member is a torsion spring, which is sleeved on the rotation shaft of the turnover beam 3. The torsion force of the torsion spring can provide the rotation driving force for the rotation of the back side of the first door body 2 for the turnover beam 3, so that when the first door body 2 is opened, the turnover beam 3 can automatically rotate towards the back side direction of the first door body 2 under the driving of the torsion spring, and the matching groove 31 can face the first end of the guide chute 51 and is opposite to the sliding column 6 when the first door body 2 is closed.

In some embodiments, the torsion spring is sleeved on the hinge portion 41 of the connection seat 4, one end arm of the torsion spring is propped against the turnover beam 3, and the other end arm of the torsion spring is propped against the connection seat 4, so that the torsion force of the torsion spring can be transferred to the turnover beam 3, the turnover beam 3 rotates towards the back side of the first door body 2, and the matching groove 31 can be opposite to the sliding column 6 when the first door body 2 is closed.

In some embodiments, the torsion spring is provided with at least one torsion spring provided on the hinge 41 of any of the connection seats 4. It should be noted that, in other embodiments, a plurality of torsion springs may be provided, and a plurality of torsion springs are provided on the hinge portions 41 of the plurality of connection seats 4 in a one-to-one correspondence. It should be noted that the number of the connection seats 4 and the number of the torsion springs may be adjusted as required, and the present invention is not limited thereto.

Therefore, when the first door body 2 is opened, the sliding post 6 can move to the first end of the guiding chute 51 under the elastic force of the elastic member 8, so as to ensure that the mating groove 31 can face the first end of the guiding chute 51 and face the sliding post 6 when the first door body 2 is closed.

Therefore, when the first door body 2 is closed, the engaging groove 31 can be disposed in front-rear facing relation with the first end of the guide chute 51, thereby causing the engaging groove 31 to be disposed in front-rear facing relation with the slide column 6. Along with the continuous closing of the first door body 2, the matching groove 31 abuts against the sliding column 6, the turnover beam 3 can push the sliding column 6 to overcome the elastic force of the elastic piece 8 through the groove wall of the matching groove 31, the first end of the guide chute 51 moves towards the direction of the second end of the guide chute 51, the turnover beam 3 rotates towards the front side direction of the first door body 2, the turnover beam 3 gradually rotates to be opened until the turnover beam 3 and the first door body 2 are arranged in parallel, and the first door body 2 and the turnover beam 3 are simultaneously attached to the front side surface of the box body 1, so that the storage compartment 10 is sealed.

Meanwhile, when the first door body 2 is opened, the elastic force of the elastic piece 8 is reset, so the elastic force of the elastic piece 8 can drive the sliding column 6 to move from the second end of the guide chute 51 towards the direction of the first end of the guide chute 51, drive the turnover beam 3 to rotate towards the back side direction of the first door body 2, be attached to the side wall of the door liner 22, provide assistance for closing the turnover beam 3, further provide assistance for opening the first door body 2, effectively reduce the door opening resistance, improve the door opening 2 inspection of a user, and improve the usability of the turnover beam 3.

In addition, set up the guide block with the upset roof beam 3 top that is correlated with and set up in the scheme of guide way in the guide holder 5, when the door body 2 was opened, the frictional force between guide block and the guide way was great, and the frictional force between cooperation groove 31 and the slip post 6 is less in this application scheme, so also can reduce the resistance of opening the door effectively, improves user's door body 2 and tests.

Fig. 15 is a schematic structural view of the guide holder 5 in fig. 13 at another view angle. Fig. 16 is an exploded view of fig. 15.

Referring to fig. 11 to 16, in some embodiments, a sliding block 7 is disposed in the guide seat 5, and the sliding block 7 is movably disposed in the guide seat 5 and above the guide chute 51. The sliding column 6 is formed on the bottom surface of the sliding block 7 in a protruding manner, and the sliding column 6 slidably penetrates the guide chute 51. The slide block 7 is laterally slidable in the guide holder 5, and the slide direction of the slide block 7 in the guide holder 5 is substantially the same as the extending direction of the guide chute 51. Therefore, when the guide holder 5 moves toward the first end of the guide chute 51, the slide column 6 can move along the guide chute 51 toward the first end of the guide chute 51. Accordingly, when the guide holder 5 moves toward the second end of the guide chute 51, the slide column 6 can move along the guide chute 51 toward the second end of the guide chute 51.

It should be noted that, in some embodiments, the sliding post 6 may be integrally formed on the bottom surface of the sliding block 7, and formed by extending downward from the bottom surface of the sliding block 7. In other embodiments, the sliding post 6 may be detachably disposed on the bottom surface of the sliding block 7, or may be telescopically disposed on the bottom surface of the sliding block 7.

Referring to fig. 11 to 16, in some embodiments, the elastic member 8 is a compression spring, and the compression spring is located on one side of the second end of the sliding block 7 near the guiding chute 51, one end of the compression spring abuts against the inside of the guiding seat 5, and the other end of the compression spring abuts against one side of the second end of the sliding block 7 near the guiding chute 51, so that the compression spring can drive the sliding block 7 to move in the direction of the first end of the guiding chute 51, and further drive the sliding column 6 to move to the first end of the guiding chute 51.

It should be noted that, in other embodiments, the elastic member 8 may also use a tension spring, where one end of the tension spring is connected to the guide seat 5 and the other end of the tension spring is connected to the sliding block 7. The sliding block 7 can be driven to move towards the first end of the guiding chute 51 by the tension of the tension spring, so that the sliding column 6 moves to the first end of the guiding chute 51.

In some embodiments, the bottom surface of the slider 7 has a dimensional width greater than the dimensional width of the guide chute 51, thereby enabling the slider 7 to slide stably over the top of the guide chute 51 without extending down into or through the guide chute 51.

Referring to fig. 11 to 16, in some embodiments, a stop collar 52 is disposed in the guide seat 5, the stop collar 52 is disposed above the guide chute 51, a movable cavity 521 is disposed in the stop collar 52, the movable cavity 521 is disposed in an upper region of the guide chute 51, and the movable cavity 521 is in communication with the guide chute 51. The sliding block 7 is movably arranged in the movable cavity 521, so that the limit is slid in the movable cavity 521 of the sliding block 7. The extending direction of the movable chamber 521 is substantially identical to the compressing direction of the guide chute 51, so that the slide column 6 can move along the guide chute 51 when the slide block 7 moves within the movable chamber 521.

Referring to fig. 15 to 16, in some embodiments, an abutment 522 is protruding from a wall of the movable chamber 521, an end of the compression spring near the second end of the guide chute 51 abuts against the abutment 522, and an end of the compression spring near the first end of the guide chute 51 abuts against the slider 7. Therefore, the slider 7 can automatically move in the direction of the first end of the guide chute 51 by the elastic force of the compression spring, thereby moving the slide column 6 to the first end of the guide chute 51.

In some embodiments, the sliding block 7 is provided with a receiving groove 71, and the receiving groove 71 is used for providing a mounting space for the elastic member 8. Specifically, the abutment 522 protrudes into the accommodating groove 71, and a first positioning post (not shown) is protruding from the abutment 522. The end wall of the receiving groove 71 near the first end of the guide chute 51 is provided with a second positioning post 72. The first positioning column is located at one side of the second positioning column 72 near the second end of the guiding chute 51, and the first positioning column is arranged opposite to the second positioning column 72. The compression spring is installed in the accommodating groove 71, and the compression spring is installed between the first positioning column and the second positioning column 72. One end of the compression spring is sleeved on the first positioning column and abuts against the abutting part 522. The other end of the compression spring is sleeved on the second positioning column 72 and abuts against the end wall of the accommodating groove 71, so that the compression spring is stably fixed in the accommodating groove 71. The compression spring is able to stabilize compressed between the first positioning post and the second positioning post as the guide post moves from the first end to the second end of the guide chute 51. When the first door body 2 is opened, the compression spring can stably drive the sliding block 7 and the sliding column 6 to move toward the first end of the guide chute 51 through the second position column.

Based on the technical scheme, the embodiment of the invention has the following advantages and positive effects:

in the refrigerator according to the embodiment of the invention, the guide seat 5 is arranged on the refrigerator body 1, the guide chute 51 in the guide seat 5 is in sliding fit with the sliding column 6, and when the door body 2 is closed, the sliding column 6 can overcome the elastic force of the elastic piece 8 by abutting against the sliding column 6 through the fit groove 31 at one side of the top of the turnover beam 3, and the turnover beam 3 can be smoothly opened to be parallel to the door body 2 by moving from the first end to the second end of the guide chute 51, so that the door body 2 and the refrigerator body 1 can be sealed. The turnover beam 3 can be rotated and reset by using the reset piece, and in the open state of the door body 2, the reset piece drives the turnover beam 3 to rotate towards the back side direction of the door body 2, so that when the door body 2 is closed, the matching groove 31 can face the first end of the guide chute 51 and is opposite to the sliding column 6, and the situation that the door body 2 cannot be closed is effectively avoided. Simultaneously the frictional force between cooperation groove 31 and the slip post 6 is less, and when the door body 2 is opened, the elasticity of elastic component 8 can provide the helping hand for turning over the closing of roof beam 3, and then can reduce the resistance of opening the door effectively, improves user's door body 2 and tests, promotes the performance of turning over roof beam 3.
