[0023] 4. Since the size of the spacing groove is comparable to the width of the movable slide rail, the movable slide rail can be limited in the spacing groove to prevent the front disassembly part and the front disassembly matching part, and the rear disassembly part and the rear disassembly matching part from accidentally separating during the sliding process of the movable slide rail, so that the side panel can be safely and firmly assembled on the movable slide rail.

[0024] When assembling, the side panels can slide left and right in the direction of the movable slide rail through the limiting effect of the spacing groove, so as to facilitate the assembly between the front disassembly part and the front disassembly matching part, and between the rear disassembly part and the rear disassembly matching part, reducing the need for users to align multiple times to complete the assembly of the above components, so that users can quickly and conveniently assemble the side panels on the movable slide rail.

[0025] 6. By utilizing the interaction between the inclined position and the inclined matching position, the side panel can be separated from the automatic and movable slide rails when disassembling and sliding, so that the user can quickly and conveniently remove the side panel from the movable slide rail, thereby improving the user experience.

[0054] Since the size of the spacing groove 12 is comparable to the width of the movable slide rail 1, the movable slide rail 1 can be limitedly set in the spacing groove 12, thereby preventing the movable slide rail 1 from accidentally separating the front disassembly portion 13 and the front disassembly matching portion 15, and the rear disassembly portion 14 and the rear disassembly matching portion 16 during the sliding process, so that the side panel 2 can be safely and firmly assembled on the movable slide rail 1.

[0055] At the same time, when assembling, the side panel 2 can slide left and right in the direction of the movable slide rail 1 through the limiting effect of the spacing groove 12, so as to facilitate the assembly between the front disassembly part 13 and the front disassembly matching part 15, and between the rear disassembly part 14 and the rear disassembly matching part 16, thereby reducing the need for users to align multiple times to complete the assembly of the above components, so that users can quickly and conveniently assemble the side panel 2 on the movable slide rail 1.

[0056] After the side panels 2, bottom panel 3 and movable slide rail 1 of the present embodiment are assembled, the bottom panel supporting portion 5 is supported on the side panel supporting portion 4 and the movable slide rail 1, the front connecting member 8 and the bottom of the rear connecting portion 9 are supported on the movable slide rail 1, the bottom panel supporting portion 6 and the vertical inner wall of the side panel 2 are mutually supported or clearance-matched, and the outer side and inner side of the movable slide rail 1 are mutually supported or clearance-matched with the side panel supporting portion 11 and the protruding portion 10 respectively, thereby effectively improving the assembly stability between the side panels 2, bottom panel 3 and movable slide rail 1, so that the side panels 2, bottom panel 3 and movable slide rail 1 are stably assembled, and the compactness of the connection between them can be improved; and when placing objects, the bottom panel 3 can disperse the force to the front connecting member 8 and the rear connecting portion 9, and then transmit it to the side panels 2 and the movable slide rail 1 by the front connecting member 8 and the rear connecting portion 9, so that the transmission of the force is more reasonable and stable, thereby improving the load-bearing capacity of the drawer assembly.

[0057] In order to facilitate the disassembly between the side plate 2 and the movable slide rail 1 , an inclined position 17 is further provided on the protruding portion 10 ; and an inclined matching position 18 is further provided on the inner side of the movable slide rail 1 .

[0058] like Fig.14 , Fig.15 As shown, when the side panel 2 is at least disassembled, the front disassembly portion 13 and the rear disassembly portion 14 are separated from the front disassembly matching portion 15 and the rear disassembly matching portion 16 respectively, and the side panel 2 slides left and right in the opposite direction of the movable slide rail 1 through the spacing groove 12. At the same time, the bottom plate support portion 5, and / or the front connecting member 8, and / or the rear connecting portion 9 are slidingly supported on the movable slide rail 1. When the side panel 2 slides to a certain position, the tilting position 17 acts on the tilting matching position 18, and drives the bottom plate support portion 5, and / or the front connecting member 8, and / or the rear connecting portion 9 to separate from the movable slide rail 1, so as to realize the disassembly between the drawer assembly and the slide rail assembly.

[0059] By utilizing the interaction between the inclined position 17 and the inclined matching position 18, the side panel 2 can be automatically separated from the movable slide rail 1 when being disassembled and slid, so that the user can quickly and conveniently remove the side panel 2 from the movable slide rail 1, thereby improving the user experience.

[0060] In order to avoid interference between the inclined position 17 and the inclined matching position 18 when the front disassembly and assembly part 13 and the front disassembly and assembly matching part 15, as well as between the rear disassembly and assembly matching part 16 are assembled with each other, resulting in the inability to function between the above-mentioned components, the inclined matching position 18 forms a front and rear spacing with the front disassembly and assembly matching part 15 and the rear disassembly and assembly matching part 16 respectively, and the side panel 2 can be placed in the front and rear spacing during assembly, thereby avoiding the problem that the front disassembly and assembly part 13 and the front disassembly and assembly matching part 15, as well as between the rear disassembly and assembly matching part 16 cannot be slidingly assembled due to the interference of the inclined position 17 and the inclined matching position 18.

[0061] The drawer assembly further comprises a panel 20 ; a front bending portion 21 is integrally bent at the front end of the side panel 2 ; and a front connecting member 8 is fixedly provided at the front end of the bottom plate assembly cavity 7 .

[0063] This embodiment also includes a drawer cabinet. The slide rail assembly also includes a fixed slide rail, which is fixedly arranged on the drawer cabinet. The movable slide rail 1 slides open and closes on the fixed slide rail. That is, the drawer assembly can slide open and close on the drawer cabinet through the cooperation of the movable slide rail 1 and the fixed slide rail.

[0064] The drawer assembly of this embodiment has a smaller width, so it is provided with two upper and lower drawer assemblies, and the upper and lower drawer assemblies are respectively fixedly connected to a panel 20. At the same time, since the width of the upper and lower drawer assemblies is smaller, their left and right sides are respectively detachably connected to the movable slide rail 1, that is, a slide rail assembly is detachably installed on the left side of the upper drawer assembly, and another slide rail assembly is detachably installed on the right side of the lower drawer assembly. The upper and lower slide rail assemblies are respectively arranged on the upper and lower drawer assemblies in an upper and lower staggered manner, so as to reasonably utilize the assembly space, and at the same time, it can also ensure that the upper and lower drawer assemblies can be stably slid open and closed on the drawer cabinet at the same time.
