[0052] The above-mentioned upper and lower anti-retraction transmission components, left and right anti-retraction transmission components, and front and rear anti-retraction transmission components are all composed of threaded transmission connections between screws and gears. Due to the threaded transmission relationship between the screws and gears, the left and right adjustment parts 9, the upper and lower adjustment parts 11, and the front and rear adjustment parts 21 will not have any retraction problems after adjustment, thereby improving the stability of the product during the adjustment process.

[0053] There are a plurality of support parts 4 , with a certain interval between them, and they are separately arranged on the inner side of the lower part of the side part 3 . Since there are a plurality of support parts 4 , the production cost can be saved.

[0054] The side portion 3 is a planar sheet metal part, and its inner side and / or outer side are basically vertical. The inner side and outer side of the side portion 3 of this embodiment are basically vertical. The planar side portion 3 can avoid the problem of forming a cavity inside the side panel shell in the prior art, resulting in less storage space inside the drawer, thereby further increasing the storage capacity inside the drawer, allowing users to store more objects and improving user experience.

[0055] A front connecting portion 22 and a rear connecting portion 23 are respectively integrally bent at the inner sides of the front and rear ends of the side surface portion 3 .

[0056] The front connecting portion 22 is provided with a front fastening position 24 and a longitudinal hole 25 , and is connected to a drawer front panel 26 in an up-and-down adjustment manner through the cooperation of the front fastening position 24 and the longitudinal hole 25 .

[0057] A rear fastening position 27 is provided on the rear connecting portion 23 , and a drawer back plate 28 is connected via the rear fastening position 27 .

[0058] The front connecting portion 22 and the rear connecting portion 23 are respectively bent integrally at the front and rear ends of the side portion 3, so that the side panel body 1 can be connected to the drawer front panel 26 and the drawer back panel 28 through the front connecting portion 22 and the rear connecting portion 23 respectively, thereby effectively simplifying the assembly process of the side panel body 1, the drawer front panel 26, and the drawer back panel 28, making the assembly between the three faster and improving the assembly efficiency. At the same time, since the side portion 3, the front connecting portion 22 and the rear connecting portion 23 are bent and formed as a whole, the production process of the side panel body 1 can be effectively simplified, making the production of the side panel body 1 more convenient and reducing the production cost.

[0059] The longitudinal hole 25 can realize the up-down position adjustment of the drawer front panel 26. When the user adjusts the drawer front panel 26 up and down, the user first loosens the fasteners acting on the front fastening position 24 and the longitudinal hole 25, and then realizes the up-down position adjustment of the drawer front panel 26 through the longitudinal guiding effect between the fasteners and the longitudinal hole 25. After the drawer front panel 26 is adjusted to the right position, the fasteners on the front fastening position 24 and the longitudinal hole 25 can be locked.

[0060] The top of the side portion 3 is flush with the tops of the front connecting portion 22 and the rear connecting portion 23. The flush side portion 3, the front connecting portion 22, and the rear connecting portion 23 can effectively save the production cost of the side panel body 1, thereby further reducing the production cost.

[0061] Second embodiment

[0062] See also Fig.10 The optimized adjustment structure of the drawer is different from the first embodiment in that: a supporting portion 4 is provided and is separately arranged on the lower inner side of the side portion 3, and one supporting portion 4 can ensure the structural strength of the side panel body 1.

[0066] The inner end of the supporting portion 4 is integrally bent downward to form a supporting portion 14 , and a notch 5 is formed between the outer side of the supporting portion 14 and the bottom of the supporting portion 4 .

[0067] Other parts not described are the same as those in the first embodiment.

[0068] Fourth embodiment

[0069] See also Fig.12 The optimized adjustment structure of the drawer is different from the first embodiment in that the lower part of the side part 3 extends downward and is integrally bent with a supporting part 4.

[0070] The inner end of the supporting portion 4 is integrally bent downward to form a supporting portion 14 , and a notch 5 is formed between the outer side of the supporting portion 14 and the bottom of the supporting portion 4 and the outer side of the side portion 3 .

[0071] Other parts not described are the same as those in the first embodiment.

[0072] Fifth embodiment

[0073] See also Fig.13 The optimized adjustment structure of the present drawer is different from that of the first embodiment in that the drawer bottom plate 12 is a metal sheet metal part, which is separately arranged and supported above the supporting part 4, the movable slide rail 2 and the upper and lower adjustment parts 11.

[0074] Other parts not described are the same as those in the first embodiment.

[0075] Sixth embodiment

[0080] In order to ensure the assembly stability of the drawer back panel 28 and the side panel body 1 and to effectively shield the drawer back panel 28 , a step 29 is preferably formed between the top of the side portion 3 and the top of the front connecting portion 22 in this embodiment.

[0081] The above design of the present embodiment is to enable the side panel body 1 to be connected to a higher-sized drawer front panel 26. Due to the arrangement of the step position 29, the side panel body 1 will not move forward and backward, shake left and right, etc. when connected to the high-sized drawer front panel 26.

[0082] At the same time, when the side panel body 1 is connected to the drawer front panel 26 of smaller height, a gap will appear between the upper part of the side panel body 1 and the upper part of the drawer front panel 26. This gap allows the user's hand to directly reach in and pull out the drawer as a whole to open it, eliminating the need to set a handle on the drawer front panel 26, thereby further saving the production cost of the drawer and improving the neatness of the drawer's appearance.
