[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0029] See also Figure 1-Figure 12 A drawer rear disassembly and assembly module includes a connecting member 1 arranged on the rear of the drawer, and also includes a positioning member 3 for assembling the drawer rear accessory 2. A snap-fit ​​assembly with an unlocked state and a snap-fit ​​state is arranged between the connecting member 1 and the positioning member 3. The drawer rear accessory 2 is connected to the positioning member 3, and the positioning member 3 of the drawer rear accessory 2 is disassembled and assembled on the connecting member 1 through the snap-fit ​​assembly.

[0030] By providing a drawer rear accessory 2 at the rear of the drawer, the heightening structure of the drawer side panel is adapted, and the drawer rear accessory 2 is provided with a positioning member 3 detachably mounted on the connecting member 1, and the connecting member 1 is connected to the drawer side panel 12, thereby realizing the detachable structure between the drawer rear accessory 2 and the side panel 12, which is convenient for the user to install the corresponding drawer rear accessory 2 according to the heightening structure of the drawer side panel 12, so as to meet the use requirements of different users. In addition, the drawer back panel does not need to be designed as a whole plate body, and the drawer rear accessory 2 and the plate body located at the bottom of the drawer rear accessory 2 are used as the drawer back panel, which can appropriately reduce the production material cost of the drawer back panel.

[0031] The buckle assembly comprises a locking and disengaging buckle part 4 , on which a guide block 5 is provided. The positioning member 3 is oriented and disassembled on the connecting member 1 through the guide block 5 of the locking and disengaging buckle part 4 .

[0032] In this embodiment, the connecting member 1 is provided with an assembly portion 7 corresponding to the guide block 5 and the locking and releasing snap-fitting portion 4. When the positioning member 3 is connected to the connecting member 1, the guide block 5 plays a role of being inserted into the assembly portion 7 in a directional manner. After the guide block 5 is inserted into the assembly portion 7, the upper and lower limits of the guide block 5 are within the assembly portion 7.

[0033] The snap-fit ​​assembly includes a locking and disengaging snap-fitting portion 4 and an elastic block 6 elastically connected to the locking and disengaging snap-fitting portion 4 . The elastic deformation of the elastic block 6 switches the unlocking state and the snap-fitting state of the snap-fitting assembly so that the positioning member 3 can be assembled and disassembled on the connecting member 1 .

[0034] In this embodiment, the elastic block 6 is inclined on the guide block 5, and an elastic deformation space for the elastic block 6 to deform is reserved between the elastic block 6 and the guide block 5. When the positioning member 3 is connected to the connecting member 1, the elastic block 6 is squeezed and elastically deformed along the elastic deformation space during the insertion of the guide block 5 into the assembly portion 7. When the guide block 5 is inserted into place, the elastic block 6 elastically deforms and resets and elastically acts on the inner side of the connecting member 1 along the assembly portion 7, so that the locking and disengaging fastening portion 4 forms an elastic fastening connection with the connecting member 1. When the disengaging fastening portion 4 of the locking and positioning member 3 is separated from the connecting member 1, it is only necessary to move the elastic block 6, and the elastic block 6 is disengaged from the connecting member 1, so that the positioning member 3 is separated from the connecting member 1.

[0035] The buckle assembly further includes an assembly portion 7 that cooperates with the locking and releasing buckle portion 4. The locking and releasing buckle portion 4 is arranged on the positioning member 3, and the assembly portion 7 is arranged on the connecting member 1; The positioning member 3 is assembled on the connecting member 1, and the elastic block 6 of the locking and snapping part 4 elastically acts on the assembly part 7, so that the locking and snapping part 4 is locked and positioned on the assembly part 7; The positioning member 3 is disassembled from the connecting member 1 , and the locking and snap-fitting portion 4 is unlocked from the assembly hole portion 7 through the elastic deformation of the elastic block 6 .

[0036] In this embodiment, in addition to the locking and disengaging engaging portion 4 and the assembly portion 7, a plug-in buckle 17 and a plug-in hole 18 are provided between the positioning member 3 and the connecting member 1. The plug-in buckle 17 includes two elastic plug-in blocks arranged at intervals, and an elastic deformation space is formed between the two elastic plug-in blocks. When the two elastic plug-in blocks of the positioning member 3 are inserted into the plug-in hole 18 of the connecting member 1, the two elastic plug-in blocks are deformed along the elastic deformation space. When the two elastic plug-in blocks are inserted into place, the two elastic plug-in blocks are elastically reset and act on the inner side of the connecting member 1. In addition, when the two elastic plug-in blocks move toward the elastic deformation space and move closer to the elastic deformation space, the plug-in buckle 17 can be separated from the plug-in hole 18, thereby realizing the disassembly and assembly between the positioning member 3 and the connecting member 1.

[0037] The locking and releasing engaging part 4 is arranged on the positioning member 3. The positioning member 3 has an opening part 8 corresponding to the elastic block 6 of the locking and releasing engaging part 4. The opening part 8 is arranged on one side of the positioning member 3. One side of the positioning member 3 forms an open operating end for operating the elastic block 6 to perform elastic deformation.

[0038] In this embodiment, since the positioning member 3 and the connecting member 1 are designed to be a detachable structure, it is necessary to provide an open operating end on the positioning member 3 for operating the elastic block 6 to elastically deform, so that the user can directly move the elastic block 6 at the open operating end to allow the positioning member 3 assembled on the connecting member 1 to be detached from the connecting member 1.

[0039] One end of the connecting member 1 is bent toward the outside of the drawer to form a connecting block 9, and an assembly portion 7 cooperating with the locking and snapping portion 4 is provided on the connecting block 9, and the locking and snapping portion 4 is locked and positioned on the assembly portion 7. The connecting member 1 is connected to the positioning member 3, and the positioning member 3 is provided with a limiting rib 14 limited on the connecting block 9 to achieve gap compensation between the positioning member 3 and the connecting block 9 of the connecting member 1, and the connecting block 9 is vertically extended along the positioning member 3 to increase the connection force area between the connecting member 1 and the positioning member 3.

[0040] In this embodiment, since the positioning member 3 is connected to the connecting block 9 bent toward the connecting member 1, when assembled in place, the limiting rib 14 of the positioning member 3 abuts against the connecting block 9 to prevent the positioning member 3 engaged on the connecting member 1 from moving back and forth on the connecting member 1.

[0041] In addition, the connecting block 9 of the connecting member 1 is vertically extended along the positioning member 3 , so that the connecting member 1 has a sufficient area for abutting against the positioning member 3 , which can increase the connection strength between the connecting member 1 and the positioning member 3 .

[0042] The positioning member 3 is provided with an assembly groove cavity 10 for assembling the drawer rear accessory 2 , and the drawer rear accessory 2 is limitedly installed in the assembly groove cavity 10 at the left and right sides and / or the upper and lower ends.

[0043] In this embodiment, the drawer rear accessory 2 is inserted into the assembly groove 10 of the positioning member 3 .

[0044] In this embodiment, the drawer rear accessory 2 has various shapes, such as a rod shape or a plate shape, and the drawer rear accessory 2 can be made of metal, plastic, glass, ceramic or wood.

[0045] The assembly groove 10 is provided with a reinforcing rib 11 for increasing the mechanical strength of the positioning member 3; the drawer rear accessory 2 is limited on the assembly groove 10 of the positioning member 3, and one side of the drawer rear accessory 2 is limited on the inner side of the reinforcing rib 11 to achieve gap compensation between the drawer rear accessory 2 and the assembly groove 10 of the positioning member 3.

[0046] In this embodiment, since the drawer rear accessory 2 is inserted into the assembly groove cavity 10 of the positioning member 3, the inserted drawer rear accessory is prevented from reciprocating on the positioning member 3.

[0047] The drawer includes a side panel 12, and a limit block 13 is provided at one end of the connecting member 1. The limit block 13 is limited on the outer side of the side panel 12 and is connected to the side panel 12. The limit block 13 is vertically extended along the side panel 12 to increase the connection force area between the connecting member 1 and the side panel 12.

[0048] In this embodiment, the limit block 13 abuts against the outer side of the side panel 12, and the limit block 13 is vertically extended along the height of the side panel 12, so that there is sufficient fitting space between the side panel 12 and the connecting member 1, effectively increasing the connection force area between the connecting member 1 and the side panel 12.

[0049] In this embodiment, the limiting block 13 is provided with a plurality of assembly holes for inserting fasteners (screws) so that the connecting member 1 and the side plate 12 can be assembled.

[0050] The drawer includes a bottom plate 15 , and a supporting block 16 is provided on the connecting member 1 . The supporting block 16 extends toward the inside of the drawer. The bottom plate 15 is limited on the inside of the connecting member 1 , and the bottom plate 15 is supported on the supporting block 16 of the connecting member 1 .

[0051] In this embodiment, the assembly structure between the side panel 12 and the bottom panel 15 can be found in Chinese patent application number ZL202010694717.6, which will not be described in detail here.

[0052] See also Figure 9-12 The drawer side panel heightening structure includes a connecting component 19, which includes a fixing component 20 and a movable component 21 connected to the fixing component 20. The fixing component 20 is provided with an assembly cavity for installing a drawer side accessory 23 and the movable component 21. A limiting edge 24 (limiting boss) is provided in the assembly cavity on the fixing component 20. The limiting edge 24 protrudes toward the assembly cavity. An elastic buckle 22 is provided on the fixing component 20. When the elastic buckle 22 of the fixing component 22 is inserted into the assembly cavity, the elastic buckle 22 is squeezed and deformed. When the elastic buckle 22 passes over the limiting edge 24, the elastic buckle 22 elastically resets and deforms and abuts against the limiting edge 24, so that the fixing component 20 is connected to the movable component 21. When the movable component 21 moves up and down along the fixing component 20, the limiting edge 24 moves up and down along the elastic buckle 22.

[0053] In this embodiment, the drawer side fitting 23 is inserted into the assembly cavity of the fixing member 20 .

[0054] In this embodiment, a limiting protrusion 25 is provided on the movable part 21, and a limiting slot 26 is provided on the fixed part 20. When the movable part 21 and the fixed part 20 are assembled, the limiting protrusion 25 is limited in the limiting slot 26. When the movable part 21 moves upward to the maximum stroke, the limiting protrusion 25 contacts the inner side of the top of the limiting slot 26. When the movable part 21 moves downward to the maximum stroke, the limiting protrusion 25 contacts the inner side of the bottom of the limiting slot 26.

[0055] In this embodiment, the fixing part 20 is fixedly connected to the panel 27 of the drawer by screws, wherein the fixing part 20 is provided with a strip hole 28 for inserting the screw. When the screws are loosened, the entire connecting assembly can be moved left and right on the panel 27 to adjust the left and right positions of the fixing part 20, the movable part 21 and the drawer side accessory 23 on the panel 27.

[0056] In this embodiment, a cavity for inserting the front connecting mechanism 30 is provided on the side panel 12, and the front connecting mechanism 30 includes a fixed box 31, a locking component 32 movably arranged on the fixed box 31 up and down, and a plug-in block 33 fixedly connected to the panel 27.

An eccentric adjustment screw 34 is provided between the fixed box 31 and the movable plate, and the eccentric adjustment screw 34 is inserted between the fixed box 31 and the movable plate. When the eccentric adjustment screw 34 rotates, the movable plate is driven to move up and down, thereby making the panel 27 move up and down, and the panel 27 is connected to the locking component 32 through the plug-in block 33.

[0057] In this embodiment, a plug-in block 33 that cooperates with the locking assembly 32 is provided on the panel 27. The plug-in block 33 and the locking assembly 32 form a front connecting mechanism 30. How to assemble the locking assembly 32 and the plug-in block 33, as well as the specific structure of the locking assembly 32 are all recorded in the background technology Chinese patent application No. ZL202311874316.9, and will not be described in detail here.

[0058] When the panel 27 moves up and down on the side panel 12, the movable part 21, the fixed part 20 and the drawer side accessory 23 are driven to move, so that there is an upper and lower spacing between the drawer side accessory 23 and the side panel 12. In order to make this upper and lower spacing smaller, it can be understood that the bottom of the drawer side accessory 23 is made to fit the top of the side panel 12 as much as possible. Therefore, the movable part 21 of the drawer side accessory 23 moves up and down along the fixed part 20. After the panel 27 is adjusted, the upper and lower positions of the drawer side accessory 23 on the inner side of the panel 27 can be adjusted, giving the user a visually beautiful effect.

[0059] Moreover, the left and right positions of the connecting components can be adjusted on the inner side of the panel 27 so that the outer side surfaces of the drawer side accessories 23 and the outer side surfaces of the side panels 12 are aligned as much as possible, giving the user a visually beautiful effect.
