The first body 71 is provided with a stop protrusion 76, and the stop protrusion 76 protrudes toward the groove wall 631 and is accommodated in the window 64.
Referring to the slide rail shown in fig. 3, when the movable rail 43 of the slide rail 40 is folded on the fixed rail 41, the fourth elastic member 93 provides a counterclockwise force, so that the movable rail locking member 90 rotates counterclockwise around the protrusion 431, and the stop protrusion 76 enters the limiting groove 92. The stopper protrusion 76 is restricted by the stopper groove 92 so that the distal end of the rail 43 is locked to the first body 71 of the push-bullet assembly 70.
As shown in fig. 7 and 8, the groove wall 631 is provided with a spacer 65 on a side away from the fitting groove 63, a slope 651 is provided at a proximal end of the spacer 65, and the spacer 65 having the slope 651 is used to assist locking and unlocking between the limit groove 92 and the stopper protrusion 76.
Specifically, the movable rail 43 moves toward the distal end of the fixed rail 41, and the movable rail lock 90 moves toward the distal end of the fixed rail 41 along with the movable rail 43, wherein the bottom of the movable rail lock 90 interacts with the oblique break 651 at the proximal end of the pad 65, the slope 65 pushes against the bottom of the movable rail lock 90 to rotate clockwise about the boss 431 (or rotate about the boss 431 in a direction opposite to the second direction), the distal end of the movable rail lock 90 is lifted, and the stopper protrusion 76 on the first body 71 enters the stopper groove 92 at the distal end of the movable rail lock 90, so that the movable rail lock 90 locks the distal end of the movable rail 43 and the push spring link 70 to each other. Continuing to move the movable rail 43, the ramp 651 guides the movable rail locking member 90 to move onto and slide on the top surface of the spacer block 65, and the stop groove 92 drives the stop protrusion 76 to slide together, so that the stop protrusion 76 slides along the window portion 64. As the movable rail 43 slides to the retracted position, the spacer 65 is coupled to the bottom of the movable rail locking member 90 and the stopper protrusion 76 slides to the distal end of the window portion 64.
In contrast, when the movable rail 43 moves from the retracted position toward the pulled-out position, the movable rail 43 moves toward the proximal end of the fixed rail 41, and the movable rail lock 90 moves toward the proximal end of the fixed rail 41 together with the movable rail 43, wherein the stopper protrusion 76 located in the stopper groove 92 of the movable rail lock 90 moves toward the proximal end of the fixed rail 41 together with the movable rail lock 90. The bottom of the movable rail locking member 90 slides along the slope 651 of the top surface of the spacer 65 toward the proximal end thereof, and the movable rail locking member 90 is guided away from the spacer 65 by the slope 651 of the proximal end of the spacer 65, and by the difference in height between the top surface of the spacer 65 and the bottom end of the slope 651 and the counterclockwise (or second direction) force applied by the fourth elastic member 93, the movable rail locking member 90 rotates around the protrusion 431 in the counterclockwise direction (or second direction), the stop protrusion 76 is disengaged from the end of the stop groove 92, the mutual limitation of the stop protrusion 76 and the distal end of the movable rail 43 is released, and the movable rail 43 can slide toward the proximal end of the fixed rail 41, driving the ice bank 22 to be pulled out of the bracket 21.
In addition, when the movable rail locking member 90 at the distal end of the movable rail 43 is engaged with the sleeve assembly 60, the push spring link 70 and the snap 80, the first elastic member 73 in the push spring link 70 and/or the second elastic member 81 in the switch 80 may provide the above-mentioned elastic force to the first body 71 of the push spring link 70, the distal end of the first body 71 is subjected to the above-mentioned elastic force, and the first body 71 moves toward the proximal end of the fixed rail 41, so that the stopper protrusion 76 on the first body 71 pushes the stopper protrusion 76 against the stopper groove 92 of the movable rail locking member 90 toward the proximal end of the window portion 64, thereby accelerating the sliding of the movable rail locking member 90 with respect to the pad 65, and when the movable rail locking member 90 moves to the ramp 651, the movable rail locking member 90 rotates in the counterclockwise direction (or the second direction) about the protrusion 431 due to the difference in height between the top surface of the pad 65 and the bottom end of the ramp 651, and the counterclockwise (or the second direction) force applied by the fourth elastic member 93, the stopper protrusion 76 is disengaged from the end of the stopper protrusion 76.
In a preferred embodiment, the ramp 651 at the proximal end of the spacer 65 is adjacent the proximal end of the window 64.
In a preferred embodiment, the limiting groove 92 is, for example, a comma groove.
In a preferred embodiment, the window 64 is, for example, an elongated slot.
By means of the sliding rail 40, when the drawer 100 is pulled out of the refrigerator compartment, the pulling and pushing of the ice bank 22 are not synchronous with the pulling and pushing of the drawer 100, that is, the drawer 100 can be pulled out first to take the ice, when the ice is required to be taken, the near end of the ice bank 22 is pressed, the moving rail 43 drives the far end of the middle rail 42 to trigger the pushing component (or the far end of the moving rail 43 triggers the pushing component), and then the moving rail 43 is pushed to slide out towards the near end of the fixed rail 41 to drive the ice bank 22 to pop out from the bracket 21.
In summary, the invention provides a sliding rail, a drawer and a refrigerator, wherein an ice making unit is accommodated in the drawer of the refrigerator, the ice making unit comprises a bracket and an ice storage box, the sliding rail is arranged between the bracket and the ice storage box, the sliding rail comprises a fixed rail and a movable rail which is in sliding fit with the fixed rail, a pushing and ejecting assembly is further arranged in the fixed rail, and the pushing and ejecting assembly can be triggered by pressing the near end of the ice storage box, so that the movable rail slides towards the near end of the fixed rail, and the ice storage box is ejected out of the bracket.
The ice storage box is opened and closed through the independent push-and-spring sliding rail relative support, and is separated from the opening stroke of the freezing drawer, after the freezing drawer is pulled out, the ice storage box is still in a closed state, and the space for storing and taking frozen foods is maximized on the premise of not influencing the ice storage box, so that the ice storage box is more convenient. The drawer with the ice making unit can meet the requirement that a user can freely access stored objects in the drawer, and meanwhile, the problem that ice cubes in the ice storage box are adhered due to the fact that the existing drawer and the ice storage box are synchronously pulled or pushed in is solved.
In addition, by pressing the proximal end of the ice bank to open the ice bank, the user interaction experience is enhanced while on-demand ice harvesting is achieved.
Of course, the present invention is capable of other various embodiments and its several details are capable of modification and variation in light of the present invention by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
