[0029] The present invention will be further described below in conjunction with the drawings and embodiments.

[0030] See Figures 1 - 7 , a drawer with an optimized assembly structure, including a drawer body 2 assembled with a drawer bottom plate 1. The drawer body 2 is provided with an extension part 3 and a supporting part 4 corresponding to the drawer bottom plate 1. A limiting groove part 5 for limiting and installing the drawer bottom plate 1 is formed between the drawer body 2, the extension part 3 and the supporting part 4. The drawer bottom plate 1 is limited up and down between the drawer body 2 and the supporting part 4. The supporting part 4 is arranged to move up and down on the limiting groove part 5, and by adjusting the up and down position of the supporting part 4 on the limiting groove part 5, it is adapted to install drawer bottom plates 1 with different thicknesses.

[0031] The supporting part 4 is an elastic deformation part. The supporting part 4 is arranged to move up and down on the limiting groove part 5 through elastic deformation, thereby adjusting the up and down distance between the drawer body 2 and the supporting part 4.

[0032] One end of the extension part 3 is provided with a connecting part 6 for increasing the mechanical strength of the extension part 3. The supporting part 4 is connected and matched with the connecting part 6.

[0033] One end of the supporting part 4 is flexibly connected, elastically connected or rigidly connected with the connecting part 6. An elastic deformation avoidance part 7 is arranged between the other end of the supporting part 4 and the connecting part 6. The supporting part 4 is arranged to elastically move on the limiting groove part 5 through the elastic deformation avoidance part 7.

[0034] In this embodiment, one end of the supporting part 4 is preferably flexibly connected with the connecting part 6. When the thickness of the drawer bottom plate 1 is greater than the up and down height position of the limiting groove part 5, when the relatively thick drawer bottom plate 1 is inserted into the limiting groove part 5, the supporting part 4 will automatically elastically deform along the lower part of the elastic deformation avoidance part 7, and the upper part of the supporting part 4 will abut against the bottom of the drawer bottom plate 1, so that the drawer bottom plate 1 is limited up and down on the limiting groove part 5. Or, when the thickness of the drawer bottom plate 1 is less than the up and down height position of the limiting groove part 5, after the drawer bottom plate 1 is inserted into the limiting groove part 5, if the up and down movement gap of the drawer bottom plate 1 is too large, the supporting part 4 can be elastically deformed along the upper part of the elastic deformation avoidance part 7 and abut against the bottom of the drawer bottom plate 1 to realize the compensation of the assembly gap.

[0035] The connecting part 6 extends horizontally relative to the extension part 3. The supporting part 4 extends along the direction of supporting the drawer bottom plate 1, and the extending direction of the supporting part 4 is the same as that of the connecting part 6. By adjusting the horizontally extending length of the supporting part 4, the supporting action area of the supporting part 4 acting on the drawer bottom plate 1 is further adjusted.

[0036] The supporting part 4 is arranged to telescopically move up and down on the connecting part 6, and the supporting part 4 is rotationally connected with the connecting part 6. The supporting part 4 adjusts its telescopic length on the connecting part 6 through rotation, thereby adjusting the up and down distance between the drawer body 2 and the supporting part 4.

[0037] In another embodiment, the connection part 6 is provided with a threaded hole, and the support part 4 is provided with a stud inserted into the threaded hole of the connection part 6. After the stud of the support part 4 is inserted into the threaded hole of the connection part 6, a nut can be sleeved on the bottom of the stud of the support part 4 to fix the position of the support part 4 on the connection part 6. The support part 4 has an initial position state and an active position state. When the height between the support part 4 in the initial position state and the inner top wall (drawer plate body 2) of the limiting groove part 5 cannot adapt to the installation of the drawer bottom plate 1 with a smaller thickness, the drawer bottom plate 1 can move up and down when inserted into the limiting groove part 5. At this time, by manually rotating the support part 4, the support part 4 moves upward along the upper side of the connection part 6 to support the bottom of the drawer bottom plate 1.

[0041] The extension part 3 is fixedly connected to the drawer plate body 2 to form a whole, or the extension part 3 is detachably mounted on the drawer plate body 2 .

[0042] In this embodiment, the extension part 3 and the drawer plate body 2 can be set as a whole through corresponding processing technology, or the extension part 3 is detachably installed on the inner side of the drawer plate body 2 by screws or buckles.

[0043] In this embodiment, both the drawer side plate 9 and the drawer back plate 10 are provided with a limiting groove portion 5 and a supporting portion 4 that moves up and down on the limiting groove portion 5 .

[0044] See also Figures 8 - 11 The rear end of the drawer side panel 9 is provided with an adjusting device 11 connected to the movable slide rail, and the adjusting device 11 includes an adjusting member 12, and the adjusting member 12 is tilted relative to the drawer side panel 9 to avoid the drawer plate body 2 (drawer bottom plate 1 and / or drawer back plate 10) when the adjusting member 12 is actuated.

[0045] The adjusting member 12 is tilted relative to the drawer back panel 10 and tilted horizontally in a direction away from the drawer back panel 10 to form a first adjustment avoidance angle a for avoiding the drawer back panel 10, and the first adjustment avoidance angle a=5~10°; when a tool is used to act on the adjusting member 12, the drawer back panel 10 can be avoided so that the drawer back panel 10 will not press against the operator's hand.

[0046] Alternatively, the adjusting member 12 is inclined relative to the drawer bottom plate 1 and vertically inclined away from the drawer bottom plate 1 to form a second adjusting avoidance angle for avoiding the drawer bottom plate 1, and the second adjusting avoidance angle = 5 - 10°; when a tool acts on the adjusting member 12, the drawer bottom plate 1 can be avoided so that the drawer bottom plate 1 does not press against the operator's hand.

[0047] Or, the adjusting member 12 is inclined relative to the drawer back plate 10 and the drawer bottom plate 1 and inclined away from the drawer back plate 10 and the drawer bottom plate 1, that is, the inclination direction of the adjusting member 12 is obliquely upward, so as to form a third adjusting avoidance angle for avoiding the drawer back plate 10 and the drawer bottom plate 1, and the third adjusting avoidance angle = 5 - 10°; when a tool acts on the adjusting member 12, the drawer back plate 10 and the drawer bottom plate 1 can be avoided so that the drawer back plate 10 and the drawer bottom plate 1 do not press against the operator's hand.
