[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0023] In the description of this invention, it should be noted that the terms "first," "second," "third," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance.
[0024] In the description of this invention, it should be noted that the terms "vertical", "horizontal", "above", "below", "upper side", "top surface" and "bottom surface" are all based on the corresponding view or the orientation in which the refrigeration equipment is placed during normal use.
[0025] Please see Figures 1-4 The present invention provides a refrigerator drawer slide assembly, which includes a first guide rail assembly 2, a first slide rail 8, and a second slide rail 9.
[0026] The first slide rail 8 and the second slide rail 9 are arranged opposite to each other, and both the first slide rail 8 and the second slide rail 9 are set on the inner liner 5 of the refrigerator.
[0027] The first guide rail assembly 2 is disposed on the first slide rail 8 and the second slide rail 9. The first guide rail assembly 2 is slidable along the length direction of the first slide rail 8. The first guide rail assembly 2 includes a first guide rail member 21 and a second guide rail member 25 disposed opposite to each other, and a first connecting frame 23 connecting the first guide rail member 21 and the second guide rail member 25. The first guide rail member 21 is in at least partial contact with the first slide rail 8, and the second guide rail member 25 is in at least partial contact with the second slide rail 9. The first guide rail member 21 and the second guide rail member 25 are used to place the first drawer 3.
[0028] Wherein, the length of the first guide rail 21 extending toward the second guide rail 25 is less than or equal to the length of the first slide rail 8 extending toward the second slide rail 9, and the length of the second guide rail 25 extending toward the first guide rail 21 is less than or equal to the length of the second slide rail 9 extending toward the first slide rail 8.
[0029] Based on the normal viewing angle of the refrigerator, the first slide rail 8 and the second slide rail 9 are set opposite each other in the horizontal direction. The first slide rail 8 can be fixed to the inner liner 5 of the refrigerator by the buckle 42.
[0030] The first guide rail 21 and the second guide rail 25 can be connected to the first connecting frame 23 by screws to form a whole. The first connecting frame 23, the first guide rail 21 and the second guide rail 25 enclose a first installation space. A first installation platform is provided on both the first guide rail 21 and the second guide rail 25. The two sides of the first drawer 3 are placed on the first installation platform, and at least a part of the first drawer 3 is located in the first installation space.
[0031] Since the length of the first guide rail 21 extending towards the second guide rail 25 is less than or equal to the length of the first slide rail 8 extending towards the second slide rail 9, that is, the length of the first guide rail 21 extending towards the second guide rail 25 does not exceed the length of the first slide rail 8 extending towards the second slide rail 9.
[0032] The length of the second guide rail 25 extending toward the first guide rail 21 is less than or equal to the length of the second slide rail 9 extending toward the first slide rail 8, that is, the length of the second guide rail 25 extending toward the first guide rail 21 does not exceed the length of the second slide rail 9 extending toward the first slide rail 8.
[0033] Therefore, the first drawer 3 is located directly above the first slide rail 8 and the second slide rail 9. Compared with the related art where the first slide rail 8 and the second slide rail 9 are located on both sides of the first drawer 3, this embodiment can increase the space for setting the first drawer 3, thereby increasing the width of the first drawer 3 and thus increasing the usable volume of the first drawer 3.
[0034] Based on the above design, this embodiment increases the width of the first drawer 3 by setting the length of the first guide rail 21 extending towards the second guide rail 25 to be less than or equal to the length of the first slide rail 8 extending towards the second slide rail 9, and by setting the length of the second guide rail 25 extending towards the first guide rail 21 to be less than or equal to the length of the second slide rail 9 extending towards the first slide rail 8. This increases the usable volume of the first drawer 3.
[0035] In one possible implementation, please refer to Figures 1-6A first roller 22 is installed on the side of the first connecting frame 23 near the first slide rail 8, and a second roller 24 is installed on the side of the first connecting frame 23 near the second slide rail 9. The first slide rail 8 includes a first mounting plate 88 and a first slide table 81 and a second slide table 82 located on the side of the first mounting plate 88 facing the second slide rail 9. The first slide table 81 and the second slide table 82 are arranged in the direction along the first slide rail 8 to the first guide rail 21. The first mounting plate 88 is connected to the refrigerator inner liner 5. A first slide groove 83 is formed between the first slide table 81 and the second slide table 82. At least a portion of the first roller 22 is located in the first slide groove 83.
[0036] The second slide rail 9 includes a first mounting post 91 and a third slide 92 and a fourth slide 93 located on the side of the first mounting post 91 facing the first slide rail 8. The third slide 92 and the fourth slide 93 are arranged in the direction along the second slide rail 9 to the second guide rail 25. The first mounting post 91 is connected to the refrigerator inner liner 5. A second slide groove 94 is formed between the third slide 92 and the fourth slide 93. At least a portion of the second roller 24 is located in the second slide groove 94.
[0037] The first slide rail 8 has a third roller 89 at one end near the refrigerator door, and the first guide rail 21 is in contact with the third roller 89 on the side near the first slide rail 8. The second slide rail 9 has a fourth roller 916 at one end near the refrigerator door, and the second guide rail 25 is in contact with the fourth roller 916 on the side near the second slide rail 9.
[0038] The connection between the first roller 22 and the second roller 24 and the first connecting frame 23 is a conventional method, such as mounting the first roller 22 and the second roller 24 on the first connecting frame 23 via a rotating shaft.
[0039] The installation method of the third roller 89 and the first slide rail 8 is conventional. For example, the third roller 89 can be installed on the first slide rail 8 through a rotating shaft. The installation method of the fourth roller 916 and the second slide rail 9 is conventional. For example, the fourth roller 916 can be installed on the second slide rail 9 through a rotating shaft.
[0040] The first guide rail 21 contacts the top of the first slide rail 8 via the third roller 89, and the second guide rail 25 contacts the top of the second slide rail 9 via the fourth roller 916.
[0041] The length of the first mounting platform on the first guide rail 21 extending toward the second guide rail 25 is less than or equal to the length of the first slide table 81 extending toward the second slide rail 9; the length of the first mounting platform on the second guide rail 25 extending toward the first guide rail 21 is less than or equal to the length of the third slide table 92 extending toward the first slide rail 8.
[0042] Based on the normal placement of the refrigerator, the first slide 81 and the second slide 82 are arranged vertically. Both the first slide 81 and the second slide 82 extend along the length of the first mounting plate 88. The first slide 81 and the second slide 82 are integrally formed with the first mounting plate 88. The first slide 81 and the second slide 82 are spaced apart, and a first slide groove 83 is formed between the first slide 81 and the second slide 82. The first roller 22 can roll along the first slide groove 83.
[0043] The third slide 92 and the fourth slide 93 are arranged vertically, and both the third slide 92 and the fourth slide 93 extend along the length of the first mounting post 91. The third slide 92 and the fourth slide 93 are integrally formed with the first mounting post 91. The third slide 92 and the fourth slide 93 are spaced apart, and a second slide groove 94 is formed between the third slide 92 and the fourth slide 93. The second roller 24 can roll along the second slide groove 94.
[0044] When the first drawer 3 needs to be pulled out, the first drawer 3 and the first guide rail assembly 2 move as a whole. The first roller 22 on the first guide rail assembly 2 rolls in the first slide groove 83, the second roller 24 rolls in the second slide groove 94, the first guide rail member 21 and the third roller 89 make rolling contact, and the second guide rail member 25 and the fourth roller 916 make rolling contact. In this way, the first guide rail assembly 2 has rolling friction with the first slide rail 8 and the second slide rail 9, which can reduce the friction between the first guide rail assembly 2 and the first slide rail 8 and the second slide rail 9, reduce the corresponding cost, and increase the service life of the first guide rail assembly 2.
[0045] In one possible implementation, please refer again. Figures 1-6 The second slide 82 has a first buffer protrusion 84 on the side near the refrigerator door, and the first buffer protrusion 84 is located on the side of the second slide 82 near the first slide 81; the fourth slide 93 has a second buffer protrusion 98 on the side near the refrigerator door, and the second buffer protrusion 98 is located on the side of the fourth slide 93 near the third slide 92.
[0046] In related technologies, when the drawer is pulled out, there is no deceleration mechanism on the slide rail, and the first guide rail assembly 2 moves at a relatively fast speed, which can easily cause injury to relevant personnel.
[0047] In this embodiment, a first buffer protrusion 84 is provided on the second slide table 82, and the first buffer protrusion 84 is located in the first slide groove 83. A second buffer protrusion 98 is provided on the fourth slide table 93, and the second buffer protrusion 98 is located in the second slide groove 94. When the first guide rail assembly 2 and the first drawer 3 are pulled out as a whole, the first roller 22 will contact the first buffer protrusion 84, and the second roller 24 will contact the second buffer protrusion 98, thereby slowing down the sliding speed of the first guide rail assembly 2 and preventing the first guide rail assembly from being pulled out too quickly and injuring people.
[0048] In one possible implementation, please refer again. Figures 1-6 The first slide rail 8 is also provided with a first limiting block 85 located on the side of the first buffer protrusion 84 near the refrigerator door. The length of the first limiting block 85 extending toward the side of the first slide table 81 is greater than the length of the first buffer protrusion 84 extending toward the side of the first slide table 81. There is a first notch 87 between the first limiting block 85 and the first buffer protrusion 84. The first notch 87 is connected to the first slide groove 83. The width of the first notch 87 is greater than the diameter of the first roller 22.
[0049] The second slide rail 9 is also provided with a second limiting block 96 located on the side of the second buffer protrusion 98 near the refrigerator door. The length of the second limiting block 96 extending toward the side of the third slide table 92 is greater than the length of the second buffer protrusion 98 extending toward the side of the third slide table 92. There is a second notch 97 between the second limiting block 96 and the second buffer protrusion 98. The second notch 97 is connected to the second slide groove 94. The width of the second notch 97 is greater than the diameter of the second roller 24.
[0050] When the first roller 22 passes the first buffer protrusion 84 and the second roller 24 passes the second buffer protrusion 98, the first roller 22 will contact the first limit block 85 and the second roller 24 will contact the second limit block 96, thereby stopping the first guide rail assembly 2 and the first drawer 3 as a whole.
[0051] Since the width of the first notch 87 is greater than the diameter of the first roller 22, and the width of the second notch 97 is greater than the diameter of the second roller 24, if it is necessary to remove the first guide rail assembly 2 from the first slide rail 8 and the second slide rail 9, the first roller 22 can be removed from the first notch 87, the second roller 24 can be removed from the second notch 97, and the first guide rail assembly 2 can be removed from the first slide rail 8 and the second slide rail 9 by rotating it by an angle of 45°-50°.
[0052] The top surface of the first limiting block 85 is flush with the top surface of the first buffer protrusion 84, and the top surface of the second limiting block 96 is flush with the top surface of the second buffer protrusion 98. When it is necessary to install the first guide rail assembly 2 on the first slide rail 8 and the second slide rail 9, the first roller 22 can be pushed into the first slide groove 83 from the first notch 87, and the second roller 24 can be pushed into the second slide groove 94 from the second notch 97. In this way, it is easier to install and remove the first guide rail assembly 2.
[0053] Optionally, the first limiting block 85 has an arc-shaped surface protruding into the first slide groove 83, and the second limiting block 96 has an arc-shaped surface protruding into the second slide groove 94. In this way, the first limiting block 85 and the second limiting block 96 have a better limiting effect on the first guide rail assembly 2.
[0054] In one possible implementation, please refer again. Figures 1-6 The first buffer protrusion 84 includes a first buffer slope 841 on the side opposite to the refrigerator door, and the second buffer protrusion 98 includes a second buffer slope 981 on the side opposite to the refrigerator door.
[0055] Both the first buffer ramp 841 and the second buffer ramp 981 are curved surfaces. When the first guide rail assembly 2 and the first drawer 3 are pulled out as a whole, the first roller 22 will contact the first buffer ramp 841, and the second roller 24 will contact the second buffer ramp 981. In this way, the sliding of the first guide rail assembly 2 can be better buffered, making it less likely to cause injury when the first guide rail assembly 2 and the first drawer 3 are pulled out as a whole.
[0056] Optionally, the first slide 81 has a first clearance groove 86 recessed in a direction away from the second slide 82 on the side facing the second slide 82, and the first clearance groove 86 is disposed opposite to the first notch 87; the third slide 92 has a second clearance groove 95 recessed in a direction away from the fourth slide 93 on the side facing the fourth slide 93, and the second clearance groove 95 is disposed opposite to the second notch 97.
[0057] The first buffer protrusion 84 is located above the first clearance groove 86, and the second buffer protrusion 98 is located above the second clearance groove 95. Both the first clearance groove 86 and the second clearance groove 95 have arc-shaped cross-sections. When the first roller 22 reaches the first buffer protrusion 84, it enters the first clearance groove 86; when the second roller 24 reaches the second buffer protrusion 98, it enters the second clearance groove 95. This facilitates easier contact between the first roller 22 and the first limiting block 85, and between the second roller 24 and the second limiting block 96. It also facilitates easier removal of the first roller 22 from the first notch 87 and the second roller 24 from the second notch 97.
[0058] In one possible implementation, please refer to Figures 1-3 and Figures 7-9 The drawer slide assembly also includes a third slide 10 and a second guide rail assembly 7.
[0059] The third slide rail 10 is located on the side of the second slide rail 9 away from the first slide rail 8, and the third slide rail 10 is connected to the refrigerator inner liner 5.
[0060] The second guide rail assembly 7 is disposed on the second slide rail 9 and the third slide rail 10. The second guide rail assembly 7 is slidable along the length direction of the first slide rail 8. The second guide rail assembly 7 includes a third guide rail member 71 and a fourth guide rail member 75 disposed opposite to each other, and a second connecting bracket 73 connected between the third guide rail member 71 and the fourth guide rail member 75. The third guide rail member 71 is in at least partial contact with the second slide rail 9, and the fourth guide rail member 75 is in at least partial contact with the third slide rail 10. The third guide rail member 71 and the fourth guide rail member 75 are used to place the second drawer 6.
[0061] Wherein, the length of the third guide rail 71 extending toward the fourth guide rail 75 is less than or equal to the length of the second slide rail 9 extending toward the third slide rail 10, and the length of the fourth guide rail 75 extending toward the third guide rail 71 is less than or equal to the length of the third slide rail 10 extending toward the second slide rail 9.
[0062] Based on the normal viewing angle of the refrigerator, the second slide rail 9 and the third slide rail 10 are set opposite each other in the horizontal direction. The third slide rail 10 can be fixed to the inner liner 5 of the refrigerator by the buckle 42.
[0063] The third guide rail 71 and the fourth guide rail 75 can be connected to the second connecting bracket 73 with screws to form a whole. The second connecting bracket 73, the third guide rail 71 and the fourth guide rail 75 enclose a second installation space. A second installation platform is provided on both the third guide rail 71 and the fourth guide rail 75. The two sides of the second drawer 6 are placed on the second installation platform, and at least a part of the second drawer 6 is located in the second installation space.
[0064] Since the length of the third guide rail 71 extending towards the fourth guide rail 75 is less than or equal to the length of the second slide rail 9 extending towards the third slide rail 10, that is, the length of the third guide rail 71 extending towards the fourth guide rail 75 does not exceed the length of the second slide rail 9 extending towards the third slide rail 10.
[0065] The length of the fourth guide rail 75 extending toward the third guide rail 71 is less than or equal to the length of the third slide rail 10 extending toward the second slide rail 9, that is, the length of the fourth guide rail 75 extending toward the third guide rail 71 does not exceed the length of the third slide rail 10 extending toward the second slide rail 9.
[0066] Therefore, the second drawer 6 is located directly above the second slide rail 9 and the third slide rail 10. Compared with the related art where the second slide rail 9 and the third slide rail 10 are located on both sides of the second drawer 6, this embodiment can increase the space for setting the second drawer 6, thereby increasing the width of the second drawer 6 and thus increasing the usable volume of the second drawer 6.
[0067] In one possible implementation, please refer to Figure 10 and Figure 11 The drawer slide assembly also includes a connecting plate 4 and a crossbeam 1.
[0068] The connecting plate 4 is provided with a buckle 42, which is engaged with the slot 51 on the inner liner 5 of the refrigerator. The connecting plate 4 is provided with a connecting protrusion 41 on the side facing the second slide rail 9, and the second slide rail 9 is provided with a connecting groove 918 on the side away from the refrigerator door. The connecting groove 918 and the connecting protrusion 41 are engaged with each other.
[0069] Both ends of the crossbeam 1 are connected to the refrigerator liner 5, and the end of the second slide rail 9 facing the refrigerator door is connected to the crossbeam 1.
[0070] The connecting plate 4 is provided with buckles 42 on the side near the second slide rail 9 and the side near the third slide rail 10. The refrigerator liner 5 is provided with slots 51 at the corresponding positions. For example, two buckles 42 can be provided on the side of the connecting plate 4 near the second slide rail 9 and two buckles 42 can be provided on the side of the connecting plate 4 near the third slide rail 10. The buckles 42 on the connecting plate 4 and the slots 51 on the refrigerator liner 5 engage with each other to install the connecting plate 4 on the refrigerator liner 5.
[0071] The crossbeam 1 can be T-shaped, and both ends of the crossbeam 1 can be screwed onto the refrigerator inner liner 5. The side of the second slide rail 9 closest to the refrigerator door can be screwed to the crossbeam 1. The connecting groove 918 on the side of the second slide rail 9 furthest from the refrigerator door engages with the connecting protrusion 41 on the connecting plate 4. This makes it easier to remove the second slide rail 9 from the connecting plate 4 and the crossbeam 1, thereby increasing the effective volume of the refrigerator.
[0072] In one possible implementation, please refer again. Figures 1-3 and Figures 7-9 The second connecting frame 73 is equipped with a fifth roller 72 on the side near the second slide rail 9, and the second connecting frame 73 is equipped with a fifth roller 72 and a sixth roller 74 on the side near the third slide rail 10. The second slide rail 9 includes a first mounting post 91 and a fifth slide table 99 and a sixth slide table 910 located on the side of the first mounting post 91 facing the third slide rail 10. The fifth slide table 99 and the sixth slide table 910 are arranged in the direction along the first slide rail 8 to the first guide rail 21. A third slide groove 911 is formed between the fifth slide table 99 and the sixth slide table 910. At least a portion of the fifth roller 72 is located in the third slide groove 911.
[0073] The third slide rail 10 includes a second mounting plate 101 and a seventh slide 102 and an eighth slide 103 located on the side of the second mounting plate 101 facing the second slide rail 9. The seventh slide 102 and the eighth slide 103 are arranged in the direction along the second slide rail 9 to the second guide rail 25. The second mounting plate 101 is connected to the refrigerator inner liner 5. A fourth slide groove 104 is formed between the seventh slide 102 and the eighth slide 103. At least a portion of the sixth roller 74 is located in the fourth slide groove 104.
[0074] The second slide rail 9 has a seventh roller 917 at one end near the refrigerator door, the third guide rail 71 is in contact with the seventh roller 917 on one side near the second slide rail 9, the third slide rail 10 has an eighth roller 109 at one end near the refrigerator door, and the fourth guide rail 75 is in contact with the eighth roller 109 on one side near the third slide rail 10.
[0075] The fifth roller 72 and the sixth roller 74 are connected to the second connecting frame 73 in a conventional manner, such as by using a pivot to install the fifth roller 72 and the sixth roller 74 on the second connecting frame 73.
[0076] The seventh roller 917 is installed on the second slide rail 9 in a conventional manner. For example, the seventh roller 917 can be installed on the second slide rail 9 via a pivot. The eighth roller 109 is installed on the third slide rail 10 in a conventional manner. For example, the eighth roller 109 can be installed on the third slide rail 10 via a pivot.
[0077] The third guide rail 71 contacts the top of the second slide rail 9 via the seventh roller 917, and the fourth guide rail 75 contacts the top of the third slide rail 10 via the eighth roller 109.
[0078] The length of the second mounting platform on the third guide rail 71 extending toward the fourth guide rail 75 is less than or equal to the length of the fifth slide table 99 extending toward the third slide rail 10; the length of the second mounting platform on the fourth guide rail 75 extending toward the third guide rail 71 is less than or equal to the length of the seventh slide table 102 extending toward the second slide rail 9.
[0079] Based on the normal viewing angle of the refrigerator, the fifth slide 99 and the sixth slide 910 are arranged vertically. Both the fifth slide 99 and the sixth slide 910 extend along the length of the first mounting post 91. The fifth slide 99 and the sixth slide 910 are integrally formed with the first mounting post 91. The fifth slide 99 and the sixth slide 910 are spaced apart, and a third slide groove 911 is formed between the fifth slide 99 and the sixth slide 910. The fifth roller 72 can slide along the third slide groove 911.
[0080] The seventh slide 102 and the eighth slide 103 are arranged vertically and extend along the length of the second mounting plate 101. The seventh slide 102 and the eighth slide 103 are integrally formed with the second mounting plate 101. The seventh slide 102 and the eighth slide 103 are spaced apart and form a fourth slide groove 104 between them. The fourth roller 916 can slide along the fourth slide groove 104.
[0081] When the second drawer 6 needs to be pulled out, the second drawer 6 and the second guide rail assembly 7 move as a whole. The third roller 89 on the second guide rail assembly 7 rolls in the third slide groove 911, the fourth roller 916 rolls in the fourth slide groove 104, the second guide rail component makes rolling contact with the seventh roller 917, and the second guide rail component makes rolling contact with the eighth roller 109. In this way, the second guide rail assembly 7 has rolling friction with the second slide rail 9 and the third slide rail 10, which can reduce the friction between the second guide rail assembly 7 and the second slide rail 9 and the third slide rail 10, reduce the corresponding cost, and increase the service life of the second guide rail assembly.
[0082] In one possible implementation, please refer again. Figures 1-3 and Figures 7-9 The sixth slide 910 has a third buffer protrusion 912 on the side near the refrigerator door, and the third buffer protrusion 912 is located on the side of the sixth slide 910 near the fifth slide 99; the eighth slide 103 has a fourth buffer protrusion 108 on the side near the refrigerator door, and the fourth buffer protrusion 108 is located on the side of the eighth slide 103 near the seventh slide 102.
[0083] In related technologies, when the drawer is pulled out, there is no deceleration mechanism on the slide rail, and the first guide rail assembly 2 moves at a relatively fast speed, which can easily cause injury to relevant personnel.
[0084] In this embodiment, a third buffer protrusion 912 is provided on the sixth slide table 910, and the third buffer protrusion 912 is located in the third slide groove 911. A fourth buffer protrusion 108 is provided on the eighth slide table 103, and the fourth buffer protrusion 108 is located in the fourth slide groove 104. When the second guide rail assembly 7 and the second drawer 6 are pulled out as a whole, the fifth roller 72 will contact the third buffer protrusion 912 and the sixth roller 74 will contact the fourth buffer protrusion 108, thereby slowing down the sliding speed of the second guide rail assembly 7 and preventing the second guide rail assembly 7 from being pulled out too quickly and injuring people.
[0085] Optionally, the second slide rail 9 is also provided with a third limiting block 914 located on the side of the third buffer protrusion 912 near the refrigerator door. The length of the third limiting block 914 extending toward the side of the fifth slide table 99 is greater than the length of the third buffer protrusion 912 extending toward the side of the fifth slide table 99. There is a third notch 915 between the third limiting block 914 and the third buffer protrusion 912. The third notch 915 is connected to the third slide groove 911. The width of the third notch 915 is greater than the diameter of the fifth roller 72.
[0086] The third slide rail 10 is also provided with a fourth limiting block 106 located on the side of the fourth buffer protrusion 108 near the refrigerator door. The length of the fourth limiting block 106 extending toward the side of the seventh slide table 102 is greater than the length of the fourth buffer protrusion 108 extending toward the side of the seventh slide table 102. There is a fourth notch 107 between the fourth limiting block 106 and the fourth buffer protrusion 108. The fourth notch 107 is connected to the fourth slide groove 104. The width of the fourth notch 107 is greater than the diameter of the sixth roller 74.
[0087] The fifth slide 99 has a third clearance groove 913 recessed in a direction away from the sixth slide 910 on the side facing the sixth slide 910, and the third clearance groove 913 is opposite to the third notch 915; the seventh slide 102 has a fourth clearance groove 105 recessed in a direction away from the eighth slide 103 on the side facing the eighth slide 103, and the fourth clearance groove 105 is opposite to the fourth notch 107.
[0088] When the fifth roller 72 passes the third buffer protrusion 912 and the sixth roller 74 passes the fourth buffer protrusion 108, the fifth roller 72 will contact the third limit block 914 and the sixth roller 74 will contact the fourth limit block 106, thereby stopping the second guide rail assembly 7 and the second drawer 6 as a whole.
[0089] Please see Figure 12 The top surface of the third limiting block 914 is flush with the top surface of the third buffer protrusion 912, and the top surface of the fourth limiting block 106 is flush with the top surface of the fourth buffer protrusion 108. Since the width of the third notch 915 is greater than the diameter of the fifth roller 72, and the width of the fourth notch 107 is greater than the diameter of the sixth roller 74, if it is necessary to remove the second guide rail assembly 7 from the second slide rail 9 and the third slide rail 10, the fifth roller 72 can be removed from the third notch 915, the sixth roller 74 can be removed from the fourth notch 107, and the first guide rail assembly 2 can be removed from the second slide rail 9 and the third slide rail 10 by rotating the angle of 45°-50°.
[0090] When it is necessary to install the second guide rail assembly 7 on the second slide rail 9 and the third slide rail 10, the fifth roller 72 can be pushed into the third slide groove 911 from the third notch 915, and the sixth roller 74 can be pushed into the fourth slide groove 104 from the fourth notch 107. This makes it easier to install and remove the second guide rail assembly 7.
[0091] Optionally, the third limiting block 914 has an arcuate surface protruding into the third slide groove 911, and the fourth limiting block 106 has an arcuate surface protruding into the fourth slide groove 104. In this way, the third limiting block 914 and the fourth limiting block 106 have a better limiting effect on the second guide rail assembly 7.
[0092] Optionally, the third buffer protrusion 912 includes a third buffer ramp 9121 on the side opposite to the refrigerator door, and the fourth buffer protrusion 108 includes a fourth buffer ramp 1081 on the side opposite to the refrigerator door.
[0093] Both the third buffer ramp 9121 and the fourth buffer ramp 1081 are curved surfaces. When the second guide rail assembly 7 and the second drawer 6 are pulled out as a whole, the fifth roller 72 will contact the third buffer ramp 9121, and the sixth roller 74 will contact the fourth buffer ramp 1081. In this way, the sliding of the second guide rail assembly 7 can be better buffered, making it less likely to cause injury when the second guide rail assembly 7 and the second drawer 6 are pulled out as a whole.
[0094] Optionally, the fifth slide 99 has a third clearance groove 913 recessed in a direction away from the sixth slide 910 on the side facing the sixth slide 910, and the third clearance groove 913 is disposed opposite to the third notch 915; the seventh slide 102 has a fourth clearance groove 105 recessed in a direction away from the eighth slide 103 on the side facing the eighth slide 103, and the fourth clearance groove 105 is disposed opposite to the fourth notch 107.
[0095] The third buffer protrusion 912 is located above the third clearance groove 913, and the fourth buffer protrusion 108 is located above the fourth clearance groove 105. Both the third clearance groove 913 and the fourth clearance groove 105 have arc-shaped cross-sections. When the fifth roller 72 reaches the third buffer protrusion 912, it enters the third clearance groove 913; when the sixth roller 74 reaches the fourth buffer protrusion 108, it enters the fourth clearance groove 105. This facilitates the contact between the fifth roller 72 and the third limiting block 914, and between the sixth roller 74 and the fourth limiting block 106. It also facilitates the removal of the fifth roller 72 from the third notch 915 and the sixth roller 74 from the fourth notch 107.
[0096] In summary, by placing the first drawer 3 directly above the first slide rail 8 and the second slide rail 9, the space for the first drawer 3 can be increased, thereby increasing the width of the first drawer 3 and thus increasing its usable volume. Similarly, by placing the second drawer 6 directly above the second slide rail 9 and the third slide rail 10, the space for the second drawer 6 can be increased, thereby increasing the width of the second drawer 6 and thus increasing its usable volume.
[0097] The side of the second slide rail 9 closest to the refrigerator door can be connected to the crossbeam 1 with screws. The connecting groove 918 on the side of the second slide rail 9 away from the refrigerator door engages with the connecting protrusion 41 on the connecting plate 4. This makes it easier to remove the second slide rail 9 from the connecting plate 4 and the crossbeam 1, thereby increasing the effective volume of the refrigerator.
[0098] When the first guide rail assembly 2 and the first drawer 3 are pulled out as a whole, the first roller 22 will contact the first buffer protrusion 84 and the second roller 24 will contact the second buffer protrusion 98, thereby slowing down the sliding speed of the first guide rail assembly 2 and preventing the first guide rail assembly 2 from being pulled out too quickly and injuring people.
[0099] When the second guide rail assembly 7 and the second drawer 6 are pulled out as a whole, the fifth roller 72 will contact the third buffer protrusion 912 and the sixth roller 74 will contact the fourth buffer protrusion 108, thereby slowing down the sliding speed of the second guide rail assembly 7 and preventing the second guide rail assembly 7 from being pulled out too quickly and causing injury.
[0100] In one possible implementation, the present invention also provides a freezing device, which includes the refrigerator drawer slide assembly described in this application.
[0101] The freezing equipment may include a refrigerator. Since the freezing equipment includes the refrigerator drawer slide assembly of this application, the drawer of the freezing equipment has a larger volume. When the drawer is pulled out, the buffer protrusion can prevent the guide rail assembly from being pulled out too fast and causing injury, thereby making the freezing equipment more competitive in the market.
[0102] The above are merely various embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
