[0036] An embodiment of the present invention provides a combined refrigerator, as Figure 1 , 5 shown, including a first refrigerator 10 and a second refrigerator 20 arranged in parallel and a connecting assembly 30 connecting the first refrigerator 10 and the second refrigerator 20. The connecting assembly 30 includes a first connecting member 1 and a second connecting member 2. The first connecting member 1 is connected to the first refrigerator 10. The first connecting member 1 is provided with a track arranged along its length direction. The track is provided with a first limiting surface 111 facing the first refrigerator 10 and a second limiting surface 121 facing the second refrigerator 20. The second connecting member 2 is connected to the second refrigerator 20. The second connecting member 2 is partially arranged in the track and is restricted from moving in the parallel direction of the first refrigerator 10 and the second refrigerator 20 under the action of the first limiting surface 111 and the second limiting surface 121.

[0037] Specifically, in this embodiment, the connecting assembly 30 is arranged at the top and bottom of the first refrigerator 10 and the second refrigerator 20. Of course, the connecting assembly 30 may also be only arranged at the top or bottom of the first refrigerator 10 and the second refrigerator 20, and the present invention does not make any restrictions. In this embodiment, the connecting assembly 30 located at the bottom of the first refrigerator 10 and the second refrigerator 20 is taken as an example for expansion. Among them, when referring to the up and down directions (including the top and bottom, etc.) in the following description, the connecting assembly 30 located at the top is opposite to the connecting assembly 30 located at the bottom. When referring to the left and right directions (including facing the first connecting member 1 or the second connecting member 2), the connecting assembly 30 located at the top is the same as the connecting assembly 30 located at the bottom.

[0038] In this embodiment, the first refrigerator 10 is arranged on the left side, the second refrigerator 20 is arranged on the right side. The first connecting member 1 extends along the front and back direction of the first refrigerator 10 and is arranged on the right side of the first refrigerator 10. There are three second connecting members 2, which are arranged at intervals on the left side of the second refrigerator 20. The second connecting member 2 is provided with rollers, and the rollers can roll in the track.

[0039] Before the first refrigerator 10 and the second refrigerator 20 are connected, first connect the first connecting member 1 to the first refrigerator 10, connect the second connecting member 2 to the second refrigerator 20, and then extend the part of the second connecting member 2 disposed on the track into the track from one end of the track, and move the second refrigerator 20 along the setting direction of the track. When the second refrigerator 20 moves along the setting direction of the track, under the action of the first limiting surface 111 and the second limiting surface 121 of the track and the rollers, the movement of the second refrigerator 20 in the left and right directions is restricted until the first refrigerator 10 and the second refrigerator 20 are flush.

[0040] Further, as Figure 5 shown, the track includes a first track 11 and a second track 12. Both the first track 11 and the second track 12 are C-shaped. The C-shaped first track 11 has an opening facing downward, and the C-shaped second track 12 has an opening facing the second connecting member 2. The left side of the first track 11 is connected to the top of the second track 12.

[0041] The second connecting member 2 is further provided with a first receiving groove 21 and a second receiving groove 22. The first receiving groove 21 has an opening facing the second connecting member 2, and the second receiving groove 22 has an opening facing the first connecting member 1. The rollers include a first roller 23 and a second roller 24. The first roller 23 includes a first wheel 231 and a first shaft 232. Both ends of the first shaft 232 are connected to the top wall and the bottom wall of the first receiving groove 21. The first wheel 231 is horizontally disposed and rotates about the axis of the first shaft 232. The second roller 24 includes a second wheel 241 and a second shaft 242. Both ends of the second shaft 242 are connected to the top and the bottom of the second receiving groove 22. The second wheel 241 is horizontally disposed and rotates about the axis of the second shaft 242.

[0042] The first wheel 231 and the first shaft 232 can be integrally provided or fixedly connected. Both ends of the first shaft 232 are rotatably connected to the first receiving groove 21, or both ends of the first shaft 232 can be fixedly connected to the first receiving groove 21, and the first wheel 231 rotates around the first shaft 232. The same applies to the second roller 24. The present invention does not limit the rolling manner of the first roller 23 and the second roller 24.

[0043] The first roller 23 and the first receiving groove 21 are arranged in the first track 11. The left end of the second roller 24 is arranged in the second track 12. The first limiting surface 111 is the side wall on the right side of the first track 11, and the second limiting surface 121 is the bottom wall (located on the left side) of the second track 12 at the end far from the opening. When the second refrigerator 20 moves along the extending direction of the track, the first roller 23 rolls on the first limiting surface 111, and the second roller 24 rolls on the second limiting surface 121. Compared with the planar friction between surfaces, the rolling friction between the roller and the surface is smaller and more labor-saving. Even when the first connecting member 1 and / or the second connecting member 2 are produced, due to tolerances, the first roller 23 cannot contact the first limiting surface 111 and the second roller 24 cannot contact the second limiting surface 121 simultaneously, and the second refrigerator 20 moves and deflects to the left or right during movement. One of the rollers can still roll on the corresponding limiting surface, which can also save effort.

[0044] As another embodiment, the second roller 24, the second receiving groove 22, and the second track 12 may not be provided. An opening is formed in the bottom wall at the end of the first receiving groove 21 far from the opening so that the first roller 23 protrudes from the first receiving groove 21. At this time, the first limiting surface 111 is still the side wall on the right side of the first receiving groove 21, and the second limiting surface 121 is the side wall on the left side of the first track 11. This embodiment can also achieve labor-saving by rolling friction on both sides of the roller, but it is not shown in the figure. This embodiment takes Figure 5 the case where the first roller 23 and the second roller 24 are provided as an example.

[0045] Furthermore, a cross plate 112 is further arranged on the first track 11. The cross plate 112 is connected to the right side wall at the opening end of the first track 11. The wall at the end of the first track 11 far from the opening is the bottom wall of the first track 11. The cross plate 112 is arranged parallel to the bottom wall of the first track 11, and the distance between the two matches the height of the first receiving groove 21 to limit the movement of the first connecting member 1 and the second connecting member 2 in the height direction. The thickness of the second wheel 241 matches the height of the second track 12, which can also limit the position in the height direction.

[0046] Preferably, as Figure 7 shown, in the direction from the back to the front, the front ends of the cross plate 112 and the bottom wall of the first track 11 gradually extend away from each other, so that the distance between the front ends of the cross plate 112 and the bottom wall of the first track 11 is larger and the front opening is larger; in the direction from the front to the back, the top of the rear end of the first receiving groove 21 gradually extends downward, so that the height of the rear end of the first receiving groove 21 gradually decreases, which is convenient for the first receiving groove 21 to extend into the first track 11.

[0047] Furthermore, the first connecting member 1 is further provided with a baffle 13, a limiting through hole 14, and a limiting post passing through the limiting through hole 14. As Figure 8As shown, the baffle 13 is arranged near the rear end of the first connector 1. When the second refrigerator 20 moves along the extending direction of the track and the second connector 2 at the rearmost side touches the baffle 13, the movement of the second refrigerator 20 is basically in place. As Figure 2 As shown, the limit through-hole 14 is arranged near the front end of the first connector 1. Specifically, the limit through-hole 14 is opened on the bottom walls of the cross plate 112 and the first track 11. The limit post passes through the limit through-hole 14 to stop the second connector 2 at the foremost side.

[0048] The baffle 13 at the rear end of the first connector 1, the limit through-hole 14 and the limit post at the front end of the first connector 1 act together to prevent the first refrigerator 10 and / or the second refrigerator 20 from moving back and forth during the process of opening and closing the door. Preferably, the limit post is composed of a bolt 151 and a nut 152.

[0049] More preferably, the limit through-hole 14 is in a long strip shape and is arranged along the front-back direction of the combined refrigerator. If the holes preset on the first refrigerator 10 and / or the second refrigerator 20 for fixing with the first connector 1 and the second connector 2 cannot be aligned in the front-back direction due to tolerances, the positions of the bolt 151 and the nut 152 in the limit through-hole 14 can be adjusted.

[0050] Furthermore, as Figure 2 As shown, the first connector 1 and the second connector 2 are respectively provided with a first adjustment hole 16 and a second adjustment hole 25. The first adjustment hole 16 extends along the juxtaposed direction of the first refrigerator 10 and the second refrigerator 20, and the first connector 1 is connected to the first refrigerator 10 through the first adjustment hole 16. The second adjustment hole 25 also extends along the juxtaposed direction of the first refrigerator 10 and the second refrigerator 20, and the second connector 2 is connected to the second refrigerator 20 through the second adjustment hole 25.

[0051] When it is necessary to adjust the distance between the first refrigerator 10 and the second refrigerator 20, before connecting the first refrigerator 10 and the second refrigerator 20, the position of the connection between the first adjustment hole 16 on the first connector 1 and the first refrigerator 10 can be adjusted first, and / or the position of the connection between the second adjustment hole 25 on the second connector 2 and the second refrigerator 20 can be adjusted to make the distance between the first refrigerator 10 and the second refrigerator 20 suitable after connection, so as to realize the versatility of the connection assembly 30.

[0052] It should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0053] The series of detailed descriptions listed above are only specific descriptions of the feasible implementation manners of the present invention, and they are not intended to limit the protection scope of the present invention. Any equivalent implementation manners or modifications made without departing from the technical spirit of the present invention shall be included within the protection scope of the present invention.
