[0037] In built-in furniture, a refrigeration device can be embedded in a cabinet, and the cabinet door can be used to cover the cabinet body, so that the outer surface of the cabinet is combined with the home decoration style. The refrigeration device can be embedded in the cabinet. Among them, the door of the refrigeration device is rotatably connected to the box body of the refrigeration device, and the door of the refrigeration device can be used to cover the accommodation space inside the box body, and the cabinet door is rotatably connected to the cabinet body. However, as the door of the refrigeration device is opened, the cabinet door is prone to interference and collision with the side wall of the cabinet, resulting in a poor use experience of the built-in refrigerator. Therefore, the present application proposes a sliding door mechanism for a built-in refrigerator to solve the defect that the built-in refrigerator is prone to interference with the side wall of the cabinet during the door opening process, affecting the use experience.

[0038] It should be noted that the sliding door mechanism of the built-in refrigerator proposed in the present application can be used for built-in refrigerators, and can also be used for built-in freezers, built-in ice makers, etc., or the door bodies of other rotatably connected refrigeration devices.

[0039] The following combines Figure 1 to describe the sliding door mechanism and refrigeration device of the built-in refrigerator of the present application.

[0040] The sliding door mechanism of the built-in refrigerator according to the first aspect embodiment of the present invention includes a box body wheel 1, a gear assembly 2, a pulley assembly 4 and a traction rope 5. The box body wheel 1 is used to be fixed to the box body of the refrigerator, and the box body wheel 1 is provided with gear teeth (not shown in the figure); the gear assembly 2 is used to be connected to the door of the refrigerator, and the gear assembly 2 meshes with the box body wheel 1; the pulley assembly 4 is in transmission connection with the gear assembly 2 through a transmission rod 3; one end of the traction rope 5 is wound around the pulley assembly 4, and the other end is used to connect the cabinet door; during the door opening process, the door rotates relative to the box body, and the gear assembly 2 rotates under the action of the box body wheel 1 to drive the pulley assembly 4 to rotate, so as to wind up the traction rope 5, and the cabinet door moves toward the door opening side of the door under the traction of the traction rope 5.

[0041] According to the sliding door mechanism of the built-in refrigerator of the embodiment of the present invention, the box body wheel 1 is fixed to the box body of the refrigerator, and the gear assembly 2 is installed on the door of the refrigerator. When the door rotates relative to the box body, that is, when the door is opened and closed, the gear assembly 2 rolls along the box body wheel 1 under the rotation of the door, so as to drive the pulley assembly 4 to rotate. One end of the traction rope 5 is wound around the pulley assembly 4, and the other end is connected to the cabinet door. Then, when the pulley assembly 4 rotates, the traction rope 5 is wound up, so as to pull the cabinet door to move. In this way, during the door opening process of the door, the cabinet door moves toward the door opening side of the door under the pulling of the traction rope 5, so as to avoid interference with the cabinet and reduce the occurrence of wear, jamming and other situations.

[0042] It can be understood that the box body wheel 1 has a fan-shaped structure, and gear teeth are provided on its outer arc. The gear teeth are engaged with the gear assembly 2 so that the gear assembly 2 can rotate along the box body wheel 1 when the box door rotates relative to the box body. The gear assembly 2 can be connected to the box door through a rotating shaft to move with the box door and rotate on the box body wheel 1. The transmission rod 3 drives the pulley assembly 4 to rotate under the rotation of the gear assembly 2. The pulley assembly 4 can be installed on the box door and realizes the rotation and winding of the traction rope 5 through its rotatable sleeve and other structures to achieve the purpose of pulling the cabinet door. It can be understood that the pulley assembly 4 is adapted to rotate under the rotation of the rotating rod. The pulley assembly 4 can include multiple pulleys, and the multiple pulleys are driven by each other through the movement of the traction rope 5. In this way, the traction direction of the traction rope 5 can be adjusted through multiple pulleys to adapt to the movement of the traction cabinet door towards the opening side of the box door. It should be noted that the side where the box door is rotatably connected to the box body is the rotation side of the box door, and the side of the box door away from its rotation side is the opening side of the box door.

[0043] According to an embodiment of the present invention, the gear assembly 2 includes a door gear 21 and a transmission gear 22. The door gear 21 is used to connect to the box door of the refrigerator. The door gear 21 is engaged with the box body wheel 1, and the door gear 21 is adapted to roll along the box body wheel 1 during the opening and closing of the box door; the transmission gear 22 is engaged with the door gear 21, and the transmission gear 22 is connected to one end of the transmission rod 3, and the pulley assembly 4 is connected to the other end of the transmission rod 3. The transmission gear 22 drives the transmission rod 3 to rotate under the rotation of the door gear 21.

[0044] In this embodiment, the door gear 21 is used to be installed on the top of the box door. It can be connected to the box door through a rotating shaft. The axis of the rotating shaft is perpendicular to the top surface of the box door, and the outer peripheral gear teeth are respectively engaged with the box body wheel 1 and the transmission wheel. In this way, by connecting the door gear 21 to the box door and connecting the transmission gear 22 to the transmission rod 3, the rotation of the gear assembly 2 during the opening and closing of the box door is realized, and it is also convenient to adjust the installation position of the rotating rod, so as to adjust the traction direction of the traction rope 5.

[0045] According to an embodiment of the present invention, both the door gear 21 and the transmission gear 22 are bevel gears. It can be understood that the bevel gears can make the axes of the door gear 21 and the transmission gear 22 perpendicular. Exemplarily, the door gear 21 rotates on the horizontal plane, the transmission gear 22 rotates on the vertical plane, the transmission rod 3 extends in the horizontal direction and is connected to the side of the transmission gear 22 facing away from the door gear 21, and the transmission rod 3 rotates with the rotation of the transmission gear 22. In this way, it is adapted to adjust the rotation direction of the pulley assembly 4, so as to adjust the traction direction of the traction rope 5. It should be noted that the perpendicularity here allows a deviation of plus or minus 10 degrees, and the certain error caused by processing should also be within the protection scope of this application.

[0046] According to an embodiment of the present utility model, the pulley assembly 4 includes a fixed pulley 41, a support rod 42, and a follower pulley 43. The fixed pulley 41 is connected to one end of the transmission rod 3 away from the transmission gear 22, and one end of the traction rope 5 is wound around the fixed pulley 41; the support rod 42 is used to support between the cabinet door and the cupboard door; the follower pulley 43 is sleeved on the support rod 42, and the traction rope 5 is led out from the fixed pulley 41 and wound around the follower pulley 43.

[0047] In this embodiment, the fixed pulley 41 can be installed on the cabinet door and is adapted to wind and reel in one end of the traction rope 5 under the rotation of the transmission rod 3. In addition, in order to further adjust the traction direction of the traction rope 5, the traction rope 5 also winds around the follower pulley 43. When the fixed pulley 41 rotates and reels in the traction rope 5, the follower pulley 43 rotates under the drive of the traction rope 5. Thus, the follower pulley 43 can adjust the traction direction of the traction rope 5. At the same time, the follower pulley 43 can also tighten the traction rope 5, facilitating the traction rope 5 to pull the cupboard door to move.

[0048] It can be understood that when the cabinet door is opened, the cupboard door can be pulled by the traction rope 5 to move towards the opening side of the cabinet door. When the cabinet door is closed, the cupboard door can be manually moved to its original position, that is, the position of the cupboard door in the closed state of the cabinet door. Of course, the cupboard door can also be slidably connected to the cabinet door through an inclined slide rail, and the cupboard door can slide along the inclined slide rail to its original position under the action of gravity.

[0049] According to an embodiment of the present utility model, the follower pulley 43 is located below the fixed pulley 41. It can be understood that the traction rope 5 is led out downward from the fixed pulley 41 and can be led out horizontally after passing through the follower pulley 43, so that the traction rope 5 pulls the cupboard door to move horizontally. The traction rope 5 being led out downward from the fixed pulley 41 is beneficial to the reeling in of the traction rope 5 to provide traction power.

[0050] According to an embodiment of the present utility model, the axis of the fixed pulley 41 is perpendicular to the axis of the follower pulley 43, so as to facilitate adjusting the traction direction of the traction rope 5 and making the cupboard door move towards the opening side of the cabinet door.

[0051] According to an embodiment of the present utility model, a round head 421 is provided at one end of the support rod 42, and the round head 421 is used to abut against the cupboard door. It can be understood that the support rod 42 is used to support the sliding of the cupboard door relative to the cabinet door and is beneficial to the installation and fixation of the follower pulley 43. Exemplarily, one end of the support rod 42 can be fixed to the cabinet door, and the round head 421 is provided at the other end of the support rod 42. By abutting the round head 421 against the cupboard door, when the cupboard door slides relative to the cabinet door, the friction between the support rod 42 and the cupboard door is reduced, facilitating the sliding of the cupboard door. Specifically, the round head 421 can be a rolling structure such as a roller, making the sliding of the cupboard door smoother.

[0052] According to an embodiment of the present utility model, one end of the support rod 42 away from the round head 421 is provided with a thread, and the support rod 42 is threadedly connected to the cabinet door through the thread.

[0053] It can be understood that one end of the support rod 42 is inserted into the cabinet door and is threadedly connected to the cabinet door. The distance between the cabinet door and the cabinet door is adjusted by the length of the support rod 42. Specifically, the depth of the support rod 42 inserted into the cabinet door can be adjusted by turning a small wrench, so as to adjust the distance between the cabinet door and the cabinet door. It should be noted that the cabinet door and the cabinet door can be connected through a connecting rail, and the cabinet door slides relative to the cabinet door in the extending direction of the rail. Based on the certain gap between the cabinet door and the cabinet door connected by the rail, the cabinet door can move back and forth relative to the cabinet door, which is convenient for adjusting the distance between the cabinet door and the cabinet door, is beneficial to reducing the shaking of the cabinet door relative to the cabinet door, and the sliding of the cabinet door is smoother.

[0054] According to an embodiment of the second aspect of the present utility model, the refrigeration device includes a box body, a box door, a cabinet door and the sliding door mechanism of the above-mentioned built-in refrigerator. The box door is rotatably connected to the box body, the cabinet door can slide relative to the box door, the box body wheel 1 is connected to the box body, the gear assembly 2 is connected to the box door, and one end of the traction rope 5 is connected to the cabinet door. It can be understood that the box body forms a containing space, and the sliding door mechanism of the built-in refrigerator is arranged on the box door of the box body, and the box door is used to open or close the containing space. The refrigeration device can be a refrigerator, or a freezer, an ice maker, such as a built-in freezer, a built-in ice maker, etc. It should be noted that the cabinet door and the refrigeration device are respectively manufactured by different manufacturers, and based on the user's selection, there will be different models of refrigeration devices and cabinet doors for assembly. The sliding door mechanism of the built-in refrigerator of the present application is located between the box door and the cabinet door, so that the cabinet door slides relative to the box door. In this way, the cabinet door can be rotatably connected to the side wall of the cabinet. For example, the cabinet door and the box door are connected by a slide rail, and the box door supports the cabinet door, and the cabinet door slides along the slide rail on the box door. In this way, the difficulty of production and manufacturing can be reduced, and at the same time, the difficulty of assembly is reduced.

[0055] It can be understood that the rotating part is used for rotating to realize the traction of the traction rope 5, and the multi-angle part can facilitate the screwing of the support rod 42. Exemplarily, the multi-angle part is in the shape of a nut, and tools such as a wrench can be clamped on the multi-angle part, so as to facilitate the adjustment of the threaded connection depth between the support rod 42 and the cabinet door, thereby further adjusting the distance between the cabinet door and the cabinet door, improving the convenience.
