This structure facilitates the installation of the bottom support frame 16, resulting in a very compact structure. The inner side is the side closest to the center of the drawer, and the inner side of the outer side panel 132 is the side opposite to the inner side panel. The outer side of the side panel 13 is the outer side of the outer side panel 132.

[0038] See Figures 1-6 The side panel 13 and the back panel 12 of the drawer 1 are connected by a back connector 15. The back connector 15 allows for easy connection and fixation of the side panel 13 and the back panel 12, and also facilitates disassembly. One end of the back connector 15 is embedded in the side panel 13 of the drawer 1 and secured with screws, while the other end surrounds the outer side of the back panel 12 of the drawer 1 and is secured with screws.

[0039] See Figures 1-8 The working principle of the above-mentioned adjustment device for tilting drawer doors is as follows: When drawer 1 tilts, rotating the adjusting element 31 drives the driving wheel 33 to rotate, which in turn drives the driven wheel 34 to rotate. The spiral protrusion 35 also rotates. Guided by the protrusion 36, the support member 32 and drawer 1 move relative to each other, thereby enabling the support member 32 to move in the vertical direction and adjusting the angle of drawer 1. This allows for adjustment of the gap between the cabinet and the drawer door panel 11, thus improving the tilting effect of the drawer door panel 11. There is no need to disassemble and reassemble the slide rail mechanism 2, making the operation very simple. By setting the bottom plate support frame 16, the adjusting device can be installed, and it is also used to fix the side panel 13 and bottom plate 14 of the drawer. The adjusting device is set on the bottom plate support frame 16, making the structure very simple and compact.
