Referring to fig. 6 and 7, the top of the turning beam 3 is convexly provided with a guide block 32 extending upwards, and the guide block 32 is fixedly connected to the top of the turning beam 3. The guide block 32 is used for matching with the guide seat 4 to guide the overturning of the overturning beam 3, namely, to drive the overturning beam 3 to overturn.

Fig. 8 is a schematic structural view of the guide shoe 4 of fig. 7. Fig. 9 is a schematic view of the structure of fig. 8 from another perspective.

Referring to fig. 2 to 9, the guide seat 4 is disposed on the top of the refrigerating compartment 11, i.e. fixed on the top wall of the cabinet 1. The guide seat 4 is opposite to the turnover beam 3, and when the door body 2 and the turnover beam 3 are closed, the guide seat 4 is just positioned at the top of the turnover beam 3.

Referring to fig. 6 and 9, the guide base 4 is provided with a guide groove 41 engaged with the guide block 32. The guide groove 41 has openings on both the bottom surface and the front side. When the door body 2 and the turnover beam 3 are closed, the guide block 32 on the top of the turnover beam 3 can enter the guide groove 41 from the front opening of the guide groove 41 and extend upward from the bottom opening of the guide groove 41 to be arranged in the guide groove 41.

Referring to fig. 8 and 9, the inner side wall of the guide groove 41 forms a guide wall 411, and the guide wall 411 has a circular arc-like curved surface structure. When the guide block 32 enters the guide groove 41, the guide block 32 can move along the guide wall 411 to drive the turnover beam 3 to turn over, so as to close the door body 2 and the turnover beam 3. The following is required, when the turnover beam 3 completely enters the guide groove 41, the door body 2 and the turnover beam 3 are in a closed state, and the turnover beam 3 is parallel to the door body 2, as shown in fig. 2 and 6; when the turning beam 3 leaves the guide groove 41, the door body 2 and the turning beam 3 are in an open state, and the turning beam 3 and the door body 2 are arranged substantially perpendicular to each other, as shown in fig. 10.

A partition block 42 is protruded from a front opening of the guide groove 41 and downwardly protruded from a top surface of the guide groove 41. The partition block 42 partitions the front-side opening of the guide groove 41 into a first inlet 412 and a second inlet 413 arranged at a left-right interval.

Wherein the first inlet 412 is used for the guide block 32 to enter and exit when the turnover beam 3 is normally closed or opened. That is, when the guide block 32 enters the guide groove 41 from the first inlet 412, the guide block 32 can move along the guide wall 411, so as to drive the turnover beam 3 to turn over, and realize normal closing of the turnover beam 3; when the guide block 32 leaves the guide groove 41 from the first entrance 412, the turnover beam 3 is normally opened.

The second inlet 413 is for the guide block 32 to enter when the overturning beam 3 is abnormally closed. The top of the guide block 32 is concavely provided with a vacancy groove 33 matched with the separation block 42, and the vacancy groove 33 is used for the separation block 42 to pass through. When the turnover beam 3 is abnormally closed, the vacancy groove 33 is opposite to the separation block 42, the guide block 32 enters the guide groove 41 from the first inlet 412 and the second inlet 413 simultaneously, and the vacancy groove 33 can prevent the separation block 42 from blocking the guide block 32 from entering the guide groove 41.

It is noted that the first inlet 412 is located at the side of the hinge mechanism 6 close to the turning beam 3, the second inlet 413 is located at the side of the hinge mechanism 6 remote from the turning beam 3, and the width of the second inlet 413 is smaller than the first inlet 412. Therefore, when the turning beam 3 is opened or closed with the door 2, the guide block 32 at the top of the turning beam 3 cannot be separated from the guide groove 41 from the second inlet 413 alone.

Referring to fig. 6 to 9, the limiting device 5 is slidably and telescopically disposed on the guide seat 4, and the limiting device 5 is configured to slidably extend into the second inlet 413, block the second inlet 413, and cooperate with the separating block 42 to limit the guide block 32, so that the guide block 32 is limited in the guide groove 41.

Fig. 10 is a schematic structural view of the turning beam 3 in fig. 6 in a normal opening and closing state.

Referring to fig. 6, 9 and 10, when the guide block 32 is located in the guide groove 41 and the door 2 drives the turning beam 3 to open in a normal state, as shown in fig. 6, the guide block 32 can be shielded by the limiting device 5 and the separating block 42 together, and cannot directly leave the guide groove 41 from the second inlet 413, and the guide block 32 can only move and rotate along the rear side walls of the limiting device 5 and the separating block 42, and further leave the guide groove 41 from the first inlet 412, as shown in fig. 10, so as to realize normal opening of the turning beam 3.

Referring to fig. 6 and 10, when the guide block 32 is located outside the guide groove 41 and the door 2 drives the turning beam 3 to close in a normal state, the turning beam 3 is substantially perpendicular to the door 2, as shown in fig. 10. At this time, the guide block 32 can enter the guide groove 41 from the first inlet 412 and move along the guide wall 411, so as to drive the turnover beam 3 to turn over, thereby achieving normal closing of the door body 2 and the turnover beam 3.

Fig. 11 is a schematic structural view of the inversion beam 3 of fig. 6 when abnormally closed.

Referring to fig. 6 and 11, when the guide block 32 is located outside the guide groove 41 and the door 2 drives the turnover beam 3 to close in an abnormal state, the turnover beam 3 is substantially parallel to the door 2, as shown in fig. 11. At this time, the notch 33 of the guide block 32 is opposite to the partition block 42, the guide block 32 enters the guide groove 41 from the first entrance 412 and the second entrance 413 simultaneously, the guide block 32 presses the position-limiting device 5 at the second entrance 413, the guide block 32 can force the position-limiting device 5 to slide and exit the guide groove 41, and the guide block 32 can enter the guide groove 41 from the second entrance 413. And after the guide block 32 completely enters the guide groove 41, as shown in fig. 6, the limiting device 5 can slide again and extend into the second inlet 413 to limit the guide block 32, so that the overturning beam 3 can be normally closed even when the operation is abnormal.

It will be appreciated that in some embodiments, the spacer 42 may be omitted, and the stopper 32 may be directly rotated by the stopper 5 and extended into the front opening of the guide groove 41 to limit the position of the guide block, which also enables normal opening and closing of the turnover beam 3 in the normal state and normal closing in the abnormal state.

However, it should be noted that, the guide block 32 and the limiting device 5 cooperate together to limit the guide block 32, so that the length of the limiting device 5 extending into the guide groove 41, that is, the width of the second inlet 413, can be greatly reduced, which is further beneficial to reducing the size and the rotation stroke of the limiting device 5, and improving the stability and the reliability of the movement of the guide block 32.

Referring to fig. 8 and 9, the peripheral wall of the guide groove 41 near the second inlet 413 is opened with a flexible opening 43, that is, the flexible opening 43 is opened at a position near the second inlet 413 of the guide wall 411. The limiting device 5 is slidably disposed in the telescopic opening 43, and the limiting device 5 can rotate and extend into the second inlet 413 through the telescopic opening 43.

When the limiting device 5 extends into the second inlet 413, the end of the limiting device 5 can be close to the separating block 42, and the rear side wall of the end can be smoothly connected with the rear side wall of the separating block 42, so that the limiting device is matched with the separating block 42 to limit the guide block 32. When the turning beam 3 is opened, the guide block 32 can move and rotate along the rear side wall of the limiting device 5 and the rear side wall of the partition block 42, and further smoothly leave the guide groove 41 from the first entrance 412, so that the turning beam 3 is opened.

It is understood that in some embodiments, the telescoping port 43 may be disposed on the top wall of the guide slot 41. The limiting device 5 is slidably arranged in the telescopic opening 43 and is positioned at the top of the guide seat 4, and the limiting device 5 can slide and extend into the second inlet 413 through the telescopic opening 43 to be matched with the separating block 42 to limit the guide block 32.

In other embodiments, the telescopic opening 43 may also be disposed on the sidewall of the partition block 42 near the second inlet 413. The limiting device 5 is arranged inside the separating block 42 and can slide into the second inlet 413 through the telescopic opening 43 to limit the guide block 32 together with the separating block 42.

Fig. 12 is a schematic structural view of the limiting device 5 in fig. 8. Fig. 13 is a top view of fig. 8, with the stop 5 extending into the second inlet 413. Fig. 14 is a schematic view of fig. 13 in another state, when the limiting means 5 is withdrawn from the second inlet 413.

Referring to fig. 12 to 14 in combination with fig. 8 and 9, the limiting device 5 includes a limiting member 51 and a resetting member 52.

The limiting member 51 is slidably connected to the guide base 4. Specifically, a sliding groove 44 communicating with the telescopic opening 43 is provided in the guide base 4, and the stopper 51 is slidably provided in the sliding groove 44. Under the pressing of the guide block 32, the limiting member 51 can slide along the sliding groove 44 to a side away from the first inlet 412 and exit from the area of the second inlet 413.

The reset member 52 is disposed on the guide seat 4 and abuts against the limiting member 51, so as to drive the limiting member 51 to extend into the second inlet 413 through the telescopic opening 43. When the guide block 32 leaves or completely enters the guide groove 41, the reset member 52 can drive the limiting member 51 to reset, and extend into and stop at the second inlet 413.

In some embodiments, the return element 52 is a compression spring disposed within the sliding channel 44. One end of the pressure spring is abutted against the guide seat 4, and the other end of the pressure spring is abutted against the limiting piece 51. The tension of the compression spring can force the limiting member 51 to slide along the sliding groove 44 and extend into the expansion opening 43, as shown in fig. 13.

When the stopper 51 is pressed to slide out of the area of the second inlet 413, the pressing spring is compressed and deformed, and the state shown in fig. 14 is obtained. Therefore, when the guide block 32 completely enters the guide groove 41, the compressed spring is released, and the compressed spring can drive the limiting member 51 to slide and reset, and then extend into the second inlet 413 area again along the sliding groove 44 and stop, as shown in fig. 13.

Referring to fig. 12 to 14, in some embodiments, a sleeve 514 is protruded from a side wall of the limiting member 51 away from the flexible opening 43, and a sleeve 45 is disposed on the guide seat 4 opposite to the sleeve 514, wherein the sleeve 45 is disposed at an end of the sliding groove 44 away from the flexible opening 43. When the compression spring is installed in the sliding groove 44, one end of the compression spring can be sleeved on the sleeve column 514, and the other end of the compression spring can be inserted into the sleeve 45.

When the limiting member 51 is extruded and slides out of the second inlet 413 region, the sleeve column 514 can drive the compression spring to be compressed and deformed, and the sleeve column 514 and the compression spring are both contained in the sleeve 45, so that the stability of the compression spring structure can be effectively ensured, and the overall expansion stroke and the required space length of the limiting device 5 can be reduced.

Referring to fig. 12 to 14, a tongue 511 is protruded from the limiting member 51 toward the sidewall of the expansion opening 43. When the reset piece 52 rotates, the latch 511 can rotate and extend into the second inlet 413.

In some embodiments, the limiting member 51 is provided with a limiting portion 512 protruding upward, and a stepped groove 513 is formed between the limiting portion 512 and the insertion tongue 511. When the tongue 511 extends into the second inlet 413 through the telescopic opening 43, the limiting part 512 can abut against the edge of the telescopic opening 43, as shown in fig. 13, the stepped groove 513 abuts against the edge of the telescopic opening 43, and the limiting part 512 can stop the limiting part 51 to prevent the limiting part from further entering the second inlet 413.

The limiting portion 512 is formed on the peripheral wall of the limiting member 51 in a protruding manner, and may be on the top, the bottom, the front side wall or the rear side wall of the limiting member 51.

Referring to fig. 9, 11 and 12, in some embodiments, the front side surface of the tongue 511 is provided with an inclined surface 5111, and the inclined surface 5111 gradually extends obliquely toward the rear side of the second inlet 413 in a direction gradually away from the expansion 43. When the guide block 32 presses the insertion tongue 511 at the second inlet 413, the guide block 32 can be engaged with the inclined surface 5111 of the insertion tongue 511, so that the insertion tongue 511 smoothly rotates along with the limiting member 51, and then exits from the second inlet 413.

Referring to fig. 6, 9 and 12, in some embodiments, the rear side of the tongue 511 is concavely provided with a smooth curved surface 5112. When the tongue 511 extends into the second inlet 413, the smooth curved surface 5112 is smoothly connected with the rear side wall of the separation block 42, and limits the guide block 32 together, so that the guide block 32 can move along the smooth curved surface 5112 and the rear side surface of the separation block 42 and leave the guide groove 41 from the first inlet 412.

It will be appreciated that in some embodiments, the end of the tongue 511 near the spacer block 42 can abut against the spacer block 42 and smoothly connect the rounded surface 5112 with the rear sidewall of the spacer block 42, so that the guide block 32 can smoothly move along the rounded surface 5112 and the rear side of the spacer block 42 and leave the guide groove 41 through the first inlet 412.

It should be noted that the reset piece 52 can also provide a certain supporting force for the limiting piece 51, so that the tongue 511 can stably stop at the area of the second entrance 413, and further, the guide block 32 can smoothly move along the smooth curved surface 5112 and the rear side surface of the separation block 42, and leave the guide groove 41 from the first entrance 412.

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

in the refrigerator of the embodiment of the invention, the door body 2 and the turnover beam 3 are matched to seal the refrigerating chamber 11, and the guide groove 41 in the guide seat 4 is matched with the guide block 32 of the turnover beam 3 to guide the movement of the turnover beam 3; meanwhile, the separating block 42 is used for separating the front side opening of the guide groove 41 into a first inlet 412 and a second inlet 413 which are spaced left and right, the guide block 32 is limited together with the separating block 42 by matching with the limiting device 5 which is connected on the guide seat 4 in a sliding manner and extends into the second inlet 413 in a sliding manner, so that the turnover beam 3 can normally enter and exit the guide groove 41 through the first inlet 412, and the normal opening and closing of the door body 2 and the turnover beam 3 are more stable.

When the turnover beam 3 is abnormally closed, the vacancy groove 33 can be opposite to the separation block 42, the guide block 32 can simultaneously enter the guide groove 41 from the first inlet 412 and the second inlet 413, the limiting device 5 is extruded at the second inlet 413, the limiting device 5 is forced to slide and exit the second inlet 413, the guide block 32 smoothly enters the guide groove 41, and finally the limiting device 5 can slide and reset and extend into the second inlet 413 again to limit the guide block 32, so that when the turnover beam 3 is in an error position due to misoperation of a user, the aim of normally closing the door can be fulfilled, and the convenience for closing the refrigerator door body 2 is improved.
