[0049] Embodiment one
[0050] Please refer to Figures 1 to 5 The present application provides a refrigerator guide rail 200, which comprises a first guide rail 201, a second guide rail 202 and a refrigerator guide rail recovery device 100. The first guide rail 201 and the second guide rail 202 are slidingly fitted, and one of the first guide rail 201 and the second guide rail 202 is installed on the cabinet of the refrigerator, and the other is installed on the drawer or the refrigerator door. A part of the refrigerator guide rail recovery device 100 is installed on the first guide rail 201, and the other part is installed on the second guide rail 202, which is used to assist the closing of the refrigerator guide rail 200 through its automatic buffering structure in the last stroke segment of the closing of the refrigerator guide rail 200, that is, it can be used to assist the automatic closing of the drawer or the refrigerator door.
[0051] Specifically, as Figures 2 to 4As shown, the refrigerator rail recycling device 100 includes a fixed frame 10, a fork piece 20 and a sliding block 30, the fixed frame 10 is used for mounting on the first rail 201 of the refrigerator, the fixed frame 10 is provided with a sliding groove 11, the sliding groove 11 has a first groove wall 111 and a second groove wall 112 arranged oppositely in the first direction x, the first groove wall 111 is located above the second groove wall 112; the fork piece 20 is used for mounting on the second rail 202 of the refrigerator; the sliding block 30 includes a main body 31 and a connecting arm 32, the main body 31 is slidably installed in the sliding groove 11 and is provided with an avoiding gap 311, the main body 31 has a first side surface 312 and a second side surface 313 arranged oppositely in the first direction x, the first side surface 312 is correspondingly and spacedly arranged with the first groove wall 111, and the second side surface 313 is correspondingly arranged with the second groove wall 112; the connecting arm 32 is arranged at the avoiding gap 311, so that the avoiding gap 311 forms a connecting groove 33; wherein the second side surface 313 includes a plane 3131 and an inclined surface 3132, the plane 3131 is attached to the second groove wall 112, and the inclined surface 3132 is arranged relatively close to the connecting arm 32 in the sliding direction y of the sliding block 30 and is connected with the plane 3131; and along the sliding direction y of the sliding block 30, one end of the inclined surface 3132 away from the plane 3131 gradually extends toward the first side surface 312 in the first direction x, so that the inclined surface 3132 is away from the second groove wall 112; wherein the first direction x is perpendicular to the sliding direction of the sliding block 30, and in response to the movement of the fork piece 20, the fork piece 20 can extrude the connecting arm 32 and make the main body 31 rotate in the first direction x toward the second groove wall 112, so as to change the gap size between the connecting arm 32 and the first groove wall 111, and make the fork piece 20 clamped into the connecting groove 33.
[0052] It needs to be explained that, by setting the plane 3131 and the inclined surface 3132, and attaching the plane 3131 to the second groove wall 112 while the inclined surface 3132 makes the second side surface 313 form a gap with the second groove wall 112. In this way, when the fork piece 20 performs the connecting action or the reset action, the fork piece 20 extrudes the sliding block 30 and makes the sliding block 30 move in the first direction x toward the second groove wall 112, so that the inclined surface 3132 approaches the second groove wall 112, and then the gap size between the connecting arm 32 and the first groove wall 111 becomes larger, and the larger gap makes the fork piece 20 more easily enter the connecting groove 33, so as to realize the connecting action. In other words, by the above structure, the sliding block 30 can reduce the clamping force on the fork piece 20 during the connecting process, that is, the resistance in the connecting process is reduced, so that the fork piece 20 is more easily reset.
[0053] As Figure 3As shown, the sliding block 30 is arranged in one piece with the main body 31. In this way, the connection structure between the sliding block 30 and the main body 31 can be reduced, the stability of the structure can be increased, and one-piece processing can simplify the production line, thereby reducing the production and processing cost and saving cost.
[0054] In an embodiment, the inclination angle of the inclined surface 3132 relative to the plane 3131 is θ, and 0 < θ ≤ 5°, so as to ensure that the sliding block can stably slide while the fork piece 20 is more easily reset.
[0055] Here, the inclination angle θ of the inclined surface 3132 relative to the plane 3131 can be 1°, 1.5°, 3°, 4°, 5°, etc., and of course is not limited thereto, and the actual value of the inclination angle θ can be determined according to specific conditions.
[0056] As shown, Figures 4 to 5 The connecting arm 32 has a first end 321 and a second end 322 arranged opposite to each other, and along the first direction x, the second end 322 is located above the first end 321. Along the sliding direction y of the sliding block 30 and from the first end 321 to the second end 322, the connecting arm 32 gradually extends upward and forms a first guide surface 323, and the fork piece 20 can be clamped into the connection slot 33 through the first guide surface 323. It can be understood that the fork piece 20 is reset from the first end 321 to the second end 322, and through the first guide surface 323, the fork piece 20 can be guided to reset, and the gap difference between the first guide surface 323 and the first slot wall 111 is increased, so that the fork piece 20 can more easily pass through the connecting arm 32 to enter the connection slot 33, thereby making the fork piece 20 easy to reset.
[0057] Specifically, the minimum gap between the second end 322 and the first slot wall 111 is a, and the maximum gap is b; the thickness of the fork piece 20 is d; and a < d < b. In this way, it can be ensured that the fork piece 20 can smoothly enter the connection slot 33 through the second end 322 when resetting, so as to realize connection; and after the connection is completed, the fork piece 20 can be stably placed in the connection slot 33, so as to ensure that it can drive the sliding block 30 to enter the locked state, so that the fork piece 20 can normally reset when the refrigerator door or the refrigerator drawer is closed.
[0058] Please continue to refer to Figure 3 The second side surface 313 is provided with a guide column 34, and the second slot wall 112 is provided with a guide groove 341 extending along the sliding direction y of the sliding block 30, and the guide column 34 is slidably arranged in the guide groove 341. In this way, by arranging the guide column 34 and the guide groove 341, the movement of the sliding block 30 is guided through the cooperation between the guide column 34 and the guide groove 341, and the movement of the sliding block 30 is more stable.
[0059] Further, an end of the guide column 34 away from the second side surface 313 is provided with a second guide surface 342, the second guide surface 342 is obliquely arranged, and the oblique direction of the second guide surface 342 is the same as that of the inclined surface 3132. It can be understood that when the fixed frame 10 is installed on the first guide rail 201 of the refrigerator, a connecting piece or a mounting piece needs to be arranged, which may affect the sliding process of the sliding block and cause the sliding block to be stuck. Therefore, the second guide surface 342 is arranged to avoid the connecting piece or the mounting piece, so as to reduce the occurrence of the stuck state of the sliding block 30 during the sliding process.
[0060] Embodiment two
[0061] The refrigerator guide rail in the embodiment two is basically the same as that in the embodiment one, and the same parts will not be repeated here. The difference lies in that the first guide rail 201 is provided with a sliding groove 11, the sliding groove 11 has a first groove wall 111 and a second groove wall 112 oppositely arranged in the first direction x, and the first groove wall 111 is located above the second groove wall 112; the refrigerator guide rail recycling device 100 comprises a yoke 20 and a sliding block 30, the yoke 20 is installed on the second guide rail 202; the sliding block 30 comprises a main body 31 and a connecting arm 32, the main body 31 is slidingly installed in the sliding groove 11 and is provided with an avoiding gap 311, the main body 31 has a first side surface 312 and a second side surface 313 oppositely arranged in the first direction x, the first side surface 312 is correspondingly and spacedly arranged with the first groove wall 111, and the second side surface 313 is correspondingly arranged with the second groove wall 112; the connecting arm 32 is arranged at the avoiding gap 311, so that the avoiding gap 311 forms a connecting groove 33; wherein the second side surface 313 comprises a flat surface 3131 and an inclined surface 3132, the flat surface 3131 is attached to the second groove wall 112, and the inclined surface 3132 is arranged relatively close to the connecting arm 32 in the sliding direction y of the sliding block 30 and is connected with the flat surface 3131; and along the sliding direction y of the sliding block 30, an end of the inclined surface 3132 away from the flat surface gradually extends toward the first side surface 312 in the first direction x, so that the inclined surface 3132 is away from the second groove wall 112. In response to the movement of the yoke 20, the yoke 20 can press the connecting arm 32 and make the main body 31 rotate in the first direction x toward the second groove wall 112, so as to change the gap size between the connecting arm 32 and the first groove wall 111, and make the yoke 20 clamped into the connecting groove 33.
[0062] Here, the sliding block 30 is directly installed on the first guide rail 201, and the fixed frame 10 in the above embodiments is omitted. The actual installation mode of the sliding block 30 can be determined according to specific conditions, which is not limited here.
[0063] The application also provides a refrigerator comprising the refrigerator guide rail 200 in any one of the above embodiments.
[0064] Each technical feature of the above-described embodiments can be combined with any other technical feature, and for the sake of brevity, not all possible combinations are described, but it is understood that the scope of the present disclosure encompasses all such possible combinations.
