FIG. 4 is an enlarged view of the A part of FIG. 2; FIG. 5 is a schematic structural diagram of a moving stopper 65 and a raised portion 69; FIG. 6 is an exploded schematic view of the moving stopper 65 and the first box body 66; , the exploded schematic diagram of the torsion spring 62 and the second box body 63; Figure 8 is a schematic diagram of the state when the push block 61 is against the rear side of the moving block 65; 10 is a schematic diagram of the state when the moving block 65 returns to the original position and the push block 61 rotates to pass over the moving block 65 .

The following describes the linkage mechanism 60 of an embodiment of the present invention with reference to FIGS. 2 to 9 , and takes the linkage mechanism 60 between the drawer 30 and the drawer 40 as an example for introduction.

The linkage mechanism 60 includes a push block 61 , a moving block 65 and a convex portion 69 . The push block 61 is installed on the top of the lower drawer 30 . The moving block 65 is provided on the lateral side wall of the upper drawer 40 so as to be movable along the lateral direction of the refrigerator. The raised portion 69 is located on the lateral side wall of the storage compartment 101 .

The linkage mechanism 60 is configured to make the push block 61 abut against the rear side of the moving block 65 when the two adjacent drawers 30 and 40 are in the closed state (as shown in FIGS. 2 and 8 ). In this way, when the lower drawer 30 moves forward, the push block 61 pushes the moving block 65, thereby driving the upper drawer 40 to move forward. And when the upper drawer 30 is pushed to the middle position (as shown in FIG. 3 ), the moving block 65 is pressed by the protrusion 69 to overcome the elastic force, and moves laterally from the original position toward the direction of approaching the drawer 40 (as shown in FIG. 8 ). The shown state moves to the left) and disengages from the push block 61, so that the two adjacent drawers 30 and 40 are released from the linkage (as shown in FIG. 9).

The linkage mechanism 60 may also be configured to cause the moving block 65 to pass over the protrusion 69 to allow the drawer 40 to continue to move forward when the upper drawer 40 in the neutral position is subjected to a forward force. After the moving block 65 passes over the protruding portion 69, it returns to the original position under the action of the elastic force. This allows the upper drawer 40 to continue to be pulled forward in order to fully open it for easy access to items by the user.

In addition, the linkage mechanism 60 is also configured to push the lower drawer 30 backward when the push block 61 is in front of the moving block 65 , so that the push block 61 contacts the moving block 65 and rotates forward against the action of the elastic torque, thereby The height of its top is lowered to go over the moving block 65, so as to return to the rear side of the moving block 65 (as shown in Fig. 10), and then return to the original position under the action of elastic torque. In addition, when the push block 61 is located in front of the moving block 65 , the upper drawer 40 can be pulled forward, and the push block 61 can also be made to pass over the moving block 65 .

5 and 6 illustrate an alternative structure of the moving block 65 and the raised portion 69 . The linkage mechanism 60 also includes a first box body 66 for installing the moving block 65 . The first box body 66 is mounted on the lateral side wall of the upper drawer 40 , and at least one mounting rod 662 (two as shown in FIG. 6 ) extends laterally outward (to the right) from the wall surface of the drawer 40 . The first box body 66 also has at least one elastic tongue 661 (4 as shown in FIG. 6 ). The moving block 65 includes a block body 651 and at least one runner 652 rotatably mounted on the block body 651 around a vertical axis, as shown in FIG. 6 , including two runners 652 arranged up and down. The block body 651 is provided with a mounting hole 6513 so as to be telescopically sleeved on the mounting rod 662 in the lateral direction, and the mounting hole 6513 can be located between the two runners 652 . The bottom wall of the first box body 66 is provided with an escape groove 665 to allow the bottom of the block body 651 to protrude out of the first case body 66 through the escape groove 665 . The right side of the first box body 66 is open, and a cover body 67 can be provided to cover the opening of the user. The cover body 67 is provided with a plurality of holes 671 so as to be fixed on the column body 664 of the first box body 66 by screws 672 (threaded holes are provided). The cover body 67 is provided with an escape opening 673 to allow the runner 652 to protrude so as to be in contact with the protruding portion 69 and be pressed by the protruding portion 69 . The contact between the runner 652 and the raised portion 69 can not only realize the lateral retraction of the moving block 65 , but also facilitate passing over the raised portion 69 because it can rotate. The elastic tongue 661 abuts against the block body 651 so as to apply elastic force to it. It can be seen that the direction of the elastic force is to the right. Specifically, each elastic tongue 661 starts from connecting to the inner wall of the first box body 66 and gradually inclines toward the direction of approaching the stopper body 651 , so as to retract laterally (ie move to the left) in the stopper body 651 to When the elastic tongue 661 is squeezed, the elastic tongue 661 is elastically deformed, and thus an elastic force is generated to generate an elastic force that pushes the block body 651 to the right. The four elastic tongues 661 are respectively connected to the four corners of the side wall of the first box body 66, the two elastic tongues 661 on the upper side extend towards the front and the rear respectively, and the two elastic tongues 661 on the lower side also face forward and backward respectively. Extend towards the rear.

As shown in FIG. 5 , the protruding portion 69 can be an independently fabricated part, which is installed on the inner wall of the storage compartment 101 . The front and rear surfaces 691 and 693 of the raised portion 69 are inclined surfaces gradually inclined toward each other from the inner wall of the storage compartment 101 outward (to the left). This facilitates the movement of the stopper 65 over the raised portion 69 .

FIG. 7 illustrates an alternative structure of the push block 61 . Each linkage mechanism 60 further includes a second box body 63 for installing the push block 61 and a torsion spring 62 . The second box body 63 is mounted on the top of the lower drawer 30 and has mounting posts 631 extending in the lateral direction. The push block 61 has a mounting hole 611 to be mounted on the mounting post 631 , and the torsion spring 62 is mounted between the second box body 63 and the push block 61 to apply elastic torque to the push block 61 . The right side of the second box body 63 is open, and is covered with a box cover 64 . The box cover 64 is provided with a hole 641 so that the screw 642 can pass through and cooperate with the threaded hole 633 opened on the second box body 63 to fix the box cover 64 . The push block 61 protrudes out of the box body 63 through the opening 635 opened at the top of the second box body 63 .

A limiting groove 6312 is defined on the peripheral surface of the mounting post 631 , and the hole wall of the mounting hole 611 has a radially protruding positioning protrusion 612 , and the positioning protrusion 612 is located in the limiting groove 6312 . When the push block 61 rotates, the positioning protrusion 612 can only move within the range of the limiting groove 6312 , thereby limiting the rotation range of the push block 61 . Specifically, when the two adjacent drawers 30 and 40 are in the closed state, as shown in FIG. 9 , the positioning protrusion 612 is pressed against the rear wall of the limiting groove 6312 , so that the push block 61 cannot be rotated backward, so that it can Push the moving block 65 forward. When the push block 61 is in front of the moving block 65 and pushes the lower drawer 30 backward, the push block 61 is allowed to rotate backwards, at most until the positioning protrusion 612 abuts against the front wall of the limiting groove 6312, That is, the rotation is stopped. At this time, the push block 61 is enough to pass over the moving block 65, so as to return to the rear side of the moving block 65 (as shown in FIG. 10), and then return to the original position under the action of elastic torque. As shown in FIG. 8 , in the state of no external force, the front surface 613 of the push block 61 is a vertical plane so as to push the moving block 65 forward, and the rear surface 614 of the push block 61 is gradually inclined forward from bottom to top. so that when it contacts with the moving stopper 65 , it goes over the moving stopper 65 .

The linkage mechanism of the refrigerator of the present invention is simple in structure, but has a very practical function. And the number of parts is small, the possibility of failure is small, and the reliability is high.

In some embodiments, in each group of two adjacent linkage mechanisms 60, the protruding portion 69 of the linkage mechanism 60 on the lower side can be located closer to the position of the protruding portion 69 of the linkage mechanism 60 on the upper side forward. In this way, after the whole set of drawers is opened, the opening degree of the drawers from top to bottom increases sequentially, similar to a stepped structure. The upper side drawer will not completely block the upper side opening of the adjacent lower side drawer, which is convenient for users to observe and access items.

As shown in Figure 1-10, only one linkage mechanism is set between every two adjacent drawers. Of course, two linkage mechanisms that are symmetrical to the left and right can also be arranged between every two adjacent drawers.

By now, those skilled in the art will recognize that, although various exemplary embodiments of the present invention have been illustrated and described in detail herein, the present invention may still be implemented in accordance with the present disclosure without departing from the spirit and scope of the present invention.
