Detailed Implementation

[0020] like Figs. 1-3 As shown, this utility model discloses a drawer panel connecting device, including a front connector 1 and a connecting component 2, for detachable connection between the drawer panel and the drawer side panel. The front connector 1 is connected to the drawer panel, and the connecting component 2 is connected to the drawer side panel. The front connector 1 and the connecting component 2 are detachably connected.

[0021] The front connector 1 has one or more locking platforms 11 at one end in the horizontal direction. The front connector 1 is provided with a panel hole 12 to connect the front connector 1 to the drawer panel. The locking platform 11 is provided with left and right adjustment screws 13 on its side. The left and right adjustment screws 13 pass through the locking platform 11 and are threadedly connected to the locking platform 11.

[0022] The connecting component 2 is installed in the installation space formed inside the drawer side panel. The connecting component 2 includes a fixing bracket 21, a height adjustment pin 22, a main board 23, a rotating buckle 24, an elastic drive locking structure, and a cover plate 25.

[0023] The fixing bracket 21 has fixing holes 211 at both the upper and lower parts for fixing the fixing bracket 21 to the drawer side panel. The central axis of the fixing hole at the upper part is horizontal, and the central axis of the fixing hole at the lower part is vertical, thus fixing the bracket in two directions for a more secure fit.

[0024] The motherboard 23 is movable up and down on the mounting bracket 21. Specifically, the height adjustment pin 22 is engaged between the mounting bracket 21 and the motherboard 23. The height adjustment pin 22 has an Archimedean spiral-shaped protrusion 221. The mounting bracket 21 has multiple vertically distributed protrusions 212 that cooperate with the protrusions 221. When the height adjustment pin 22 is adjusted upward, the protrusions 221 on the height adjustment pin 22 will engage with the multiple protrusions 212 in a bottom-to-top direction, thereby achieving height adjustment. Conversely, the same applies. Thus, by rotating the height adjustment pin 22, the height adjustment pin 22 can be moved up and down at the protrusions 212, and the height adjustment pin 22 can drive the motherboard 23 to move. The motherboard 23 is provided with a channel for the mounting bracket 11 to engage.

[0025] The rotating buckle 24 is rotatably mounted between the main plate 23 and the cover plate 25 via rivets. The number of rotating buckles 24 is the same as the number of snap-fit ​​sections 11, and they can be connected one-to-one. The rotating buckle 24 includes a main rotating buckle 241 and a secondary rotating buckle 242. An elastic drive locking structure is connected to the main rotating buckle 241 and is used to drive the main rotating buckle 241 to snap onto and lock the snap-fit ​​section 11. Specifically, the elastic drive locking device includes a swing block 26, a torsion spring 27, a sliding pin 28, and a spring piece 29. The swing block 26 is rotatably mounted between the main plate 23 and the cover plate 25 via rivets. The swing block 26 has a limiting channel 261 through which a sliding pin 28 passes and is slidably connected. The limiting channel 261 is an elliptical arc-shaped hole. The swing block 26 rotates the main rotating latch 241 by means of the limiting channel 261 and the sliding pin 28. The main plate 23 has a folding plate portion into which a torsion spring 27 is fitted. The two ends of the torsion spring 27 are respectively pressed against the main plate 23 and the swing block 26. Only a small amount of pressure applied to the drawer panel... When the trigger force is applied and the inner end of the main rotating buckle 241 is activated, the torsion spring 27 pushes the swing block 26 to rotate downwards. The swing block 26 moves the sliding pin 28 through the limiting channel, and the sliding pin 28 causes the main rotating buckle 241 to rotate downwards. The main rotating buckle 241 then moves the front connector 1 forward, and the locking platform 11 on the front connector 1 is locked. The spring piece 29 is locked onto the main board 23. The spring piece 29 has a locking position for the main rotating buckle 241 to lock onto. The main rotating buckle 241 is provided with a cross hole 2411. The main rotating latch 241 pushes open the spring clip 29 and is blocked by the snap-fit ​​position of the spring clip 29, thus reliably limiting the front connector 1. When the drawer panel is pulled, it can prevent the front connector 1 from being pulled out. When disassembling, insert a Phillips screwdriver into the Phillips hole 241 and push open the spring clip 29. The spring clip 29 will elastically deform and release the spring clip 29 from limiting the main rotating latch 241. At this time, push the main rotating latch 241 upward to release the main rotating latch 241 from limiting the front connector 1.

[0026] The secondary rotary buckle 242 is connected to the primary rotary buckle 241 via a linkage rod 243. The linkage rod 243 is hinged to both the primary rotary buckle 241 and the secondary rotary buckle 242, so that when the primary rotary buckle rotates, it drives the secondary rotary buckle to rotate, thereby achieving engagement and disengagement with the locking platform.

[0027] During installation, attach the connecting assembly to the drawer side panel, connect the fixing bracket to the drawer side panel, install the front connector onto the drawer front panel, push the drawer front panel to move the front connector toward the channel on the main board, and after touching the inner end of the main rotating latch, the main rotating latch, driven by the swing block, latches onto the locking platform. The secondary rotating latch, driven by the main rotating latch, also engages the locking platform. The main rotating latch pushes open the spring clip and is blocked by the spring clip's locking position, preventing the front connector from being pulled out. During disassembly, insert a Phillips screwdriver into the Phillips hole and push open the spring clip. The spring clip deforms elastically, releasing its restriction on the main rotating latch. At this point, push the main rotating latch upwards. The secondary rotating latch, driven by the main rotating latch, also disengages from the locking platform, releasing the rotation latch's restriction on the front connector. Then, the front connector can be pulled out from the connecting assembly through the drawer front panel.

[0028] To adjust the drawer panel height, rotate the height adjustment screw. The screw moves up and down on the protrusion of the mounting bracket, which in turn moves the main plate up and down. The main plate then moves the front bracket up and down, which in turn moves the drawer panel up and down, thus adjusting the drawer panel height. To adjust the left and right position of the drawer panel, rotate the left and right adjustment screw. When the screw is against the main plate, further rotation will cause the front bracket to move slightly to the left. Similarly, rotating the screw in the opposite direction will cause it to be against the cover plate, and further rotation will cause the front bracket to move slightly to the right, thus allowing for slight left and right adjustments to the drawer panel.

[0029] This utility model achieves a stable connection of the panel of a tall drawer by setting multiple locking platforms on the front connector and multiple rotating buckles on the connecting components.

[0030] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
