[0027] The present invention will now be further described with reference to the accompanying drawings.

[0028] According to the appendix Figures 1 to 7 As shown, the front panel connection assembly of the present invention includes a connecting component for assembling with a front panel and a snap-fit ​​component for assembling with a side panel. The connecting component includes a multi-layer laminated plate assembly 1 and expansion screws 2. The multi-layer laminated plate assembly 1 includes a first laminated plate 11, a second laminated plate 12, a third laminated plate 13, and a fourth laminated plate 14. The first laminated plate 11 has a chamfered hole 3 for positioning and installing the head end of the expansion screw 2; the second laminated plate 12 has a round hole 4 for the threaded end of the expansion screw 2 to pass through; the third laminated plate 13 has a wide groove 5 for engaging with the expansion head of the expansion screw 2; and the fourth laminated plate 14 has a fixing groove 6 for fixing the expansion head of the expansion screw 2. The first stacked piece 11, the second stacked piece 12, the third stacked piece 13, and the fourth stacked piece 14 are stacked in sequence, so that the chamfered hole 3, the round hole 4, the wide groove 5, and the fixing groove 6 are connected in sequence and form an irregular mounting position for installing the expansion screw 2. The snap-fit ​​assembly is fitted onto the first stacked piece 11, the second stacked piece 12, the third stacked piece 13, and the fourth stacked piece 14.

[0029] The front panel connection assembly uses multi-layered laminated plates to form irregularly shaped mounting positions, thereby enabling the multi-layered laminated plate assembly 1 to be assembled with the expansion screws 2, strengthening the structural connection stability, improving the tensile strength of the device, solving the structural problems that cannot be processed by the integrated bracket component, and preventing the front panel and side panel from becoming loose during use.

[0030] Meanwhile, between the first stack 11, the second stack 12, the third stack 13, and the fourth stack 14, there are protrusions 19 and connecting grooves 20 for positioning and stacking them in sequence, and the protrusions 19 are fitted into the connecting grooves 20.

[0031] With the assistance of the protruding post 19 and the connecting groove 20, assembly is simple. Furthermore, the multi-layered laminated plate assembly 1 of this structure is easy to process, enhances structural stability, and prevents deformation. Additionally, character recognition can be added to the corresponding laminated plates to fulfill product functional requirements, adapting to the assembly of various customized furniture and offering wide applicability.

[0032] Reference Figures 1 to 7 As shown in further detail, the first stacked piece 11, the second stacked piece 12, and the third stacked piece 13 are respectively provided with mounting grooves 7 on their left and right sides.

The front ends of the dual-stage left latching block 161 and the dual-stage right latching block 162 respectively have bent edges 9 that latch onto the side of the third stack 13 and are connected side-by-side with the fourth stack 14. The mounting groove 7 is provided with latching blocks 17 integrally formed with the first stack 11 and the second stack 12. The dual-stage left latching block 161 and the dual-stage right latching block 162 are respectively provided with latching holes 18 that are matched and fastened to the latching blocks 17. The double-stage left locking block 161 and the double-stage right locking block 162 are provided with double-stage fixing nails 164 that are fixedly connected to each other, and the left and right ends of the double-stage adjusting screw 163 are threadedly connected to the double-stage left locking block 161 and the double-stage right locking block 162 respectively.

[0036] This structure employs a combination of a single-stage snap-fit ​​assembly 15 and a double-stage snap-fit ​​assembly to accommodate the installation of large drawer panels. Furthermore, the double-stage adjusting screw 163 of the double-stage snap-fit ​​assembly allows for easy adjustment of the front panel's left-right installation position relative to the side panels using only a screwdriver. This facilitates operation and improves assembly quality. In addition, the structure of the snap-fit ​​block 17 and the snap-fit ​​hole 18 strengthens the upper, lower, front, and rear positioning tensile structure, further enhancing structural stability.

The single-stage left locking block 101 and the single-stage right locking block 102 are respectively embedded in the corresponding mounting grooves 7. The front ends of the single-stage left locking block 101 and the single-stage right locking block 102 are respectively provided with bent edges 9 that engage with the side of the third stack 13 and are connected side-by-side with the fourth stack 14. The mounting groove 7 is provided with a snap-fit ​​block 17 integrally formed with the first stack 11 and the second stack 12. The single-stage left locking block 101 and the single-stage right locking block 102 are respectively provided with snap-fit ​​holes 18 that engage with the snap-fit ​​block 17. The single-stage fixing pins 104 are provided between the single-stage left locking block 101 and the single-stage right locking block 102 and are fixedly connected to each other. The left and right ends of the single-stage adjusting screw 103 are respectively threaded to the single-stage left locking block 101 and the single-stage right locking block 102.

[0038] This structure employs a single-stage snap-fit ​​assembly to accommodate small drawer panels. Furthermore, the single-stage adjusting screw 103 of the single-stage adjusting snap-fit ​​assembly 10 allows for easy adjustment of the front panel's left-right mounting position relative to the side panel using only a screwdriver. This facilitates operation and improves assembly quality. Simultaneously, the structure of the snap-fit ​​block 17 and the snap-fit ​​hole 18 reinforces the upper, lower, front, and rear positioning tensile structure, further enhancing structural stability.

[0039] The above specific embodiments are merely specific implementations of the present invention with better effects. Any structure that is the same as or equivalent to the front panel connection assembly of the present invention is within the protection scope of the present invention.
