[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] See Figures 1-6 , a quick adjustment device for a drawer, comprising a fixing member 10, a lifting adjustment module 20 is arranged on the fixing member 10, the lifting adjustment module 20 includes a moving member 310 that moves up and down relative to the fixing member 10 and an adjusting member 320 that is rotatably arranged on the fixing member 10, a spiral track 321 is arranged on the adjusting member 320, a cooperating portion 311 is arranged on the moving member 310, and the cooperating portion 311 cooperates with the spiral track 321; when the adjusting member 320 rotates, the spiral track 321 cooperates with the cooperating portion 311 to drive the moving member 310 to move up and down relative to the fixing member 10.

[0027] In the present invention, by cooperating the cooperating portion with the bolt track, when the adjusting member rotates, the spiral track cooperates with the cooperating portion to drive the moving member to move up and down relative to the fixing member. The cooperation of the spiral track and the cooperating portion can avoid problems such as thread slipping existing in the existing use of bolts.

[0028] See Figure 4 , the adjusting member 320 has an annular structure, and the moving member 310 is arranged inside the adjusting member 320; a driving block 323 is arranged on the inner wall of the adjusting member 320, the upper surface of the driving block 323 is a spiral inclined surface, and the spiral inclined surface forms the spiral track 321, and the lower end surface of the cooperating portion 311 is attached to the spiral inclined surface. As the spiral inclined surface changes, it can drive the driving block 323 to move up or down.

[0029] See Figure 4 , a plurality of first positioning grooves 322 are arranged in a circumferential array along the circumferential wall of the adjusting member 320, a first elastic portion 340 is arranged on the fixing member 10, a first positioning portion 350 is arranged on the first elastic portion 340, and the first positioning portion 350 is movably clamped into any one of the first positioning grooves 322. The cooperation between the first positioning portion 350 and the first positioning groove 322 can effectively restrict the rotation of the adjusting member 320 and prevent it from rotating randomly. When the adjusting member 320 is rotated by an acting force, it presses the first positioning portion 350, causing the first elastic portion 340 to deform, so that the first positioning portion 350 can be disengaged from the first positioning groove 322.

[0030] See Figure 4 , a limiting boss 324 is provided on the adjusting member 320, and the upper surface of the limiting boss 324 is attached to the lower surface of the first positioning portion 350. In this embodiment, the cooperation between the first positioning portion 350 and the limiting boss 324 can restrict the up and down movement of the adjusting member 320.

[0031] See Figure 4 , the inside of the moving member 310 is hollow to form a guiding groove 314, the fixing member 10 is movably inserted into a guiding block 120 in the guiding groove 314, a limiting card slot 313 is provided on the groove wall of the guiding groove 314, and a limiting buckle 130 that is snapped into the limiting card slot 313 is provided on the guiding block 120. The cooperation between the guiding groove 314 and the guiding block 120 can restrict the moving member 310 to only move up and down relative to the fixing member 10, and the cooperation between the limiting buckle 130 and the limiting card slot 313 prevents the guiding block 120 from separating from the moving member 310.

[0032] See Figure 4 , a plurality of second positioning grooves 312 are arranged in a circumferential array along the circumferential wall of the moving member 310, a second elastic portion 360 is provided on the adjusting member 320, a second positioning portion 370 is provided on the second elastic portion 360, and the second positioning portion 370 is movably snapped into any one of the second positioning grooves 312.

[0033] See Figure 4 , an installation groove 110 is provided on the fixing member 10, and the moving member 310 and the adjusting member 320 are arranged in the installation groove 110.

[0034] See Figure 5 and Figure 6 , a slot 140 is provided on the fixing member 10, and a locking pin 40 is movably inserted into the slot 140.

[0035] See Figure 5 , the locking pin 40 includes a pin rod 410 movably inserted into the slot 140, an operating rod 420 is provided at one end of the pin rod 410, a positioning groove 430 is provided on the pin rod 410, and a positioning projection 150 that is engaged and cooperated with the positioning groove 430 is provided in the slot 140.

[0036] See Figure 6 , the use of the locking pin 40 is that it can be inserted into a pre-opened locking groove 510 of the drawer 50, and it can restrict the range of up and down movement of the drawer relative to the movable rail 20, avoiding the separation of the drawer 50 from the movable rail 20.

[0037] See Figure 2, a lever 330 is provided on the adjusting member 320. The function of the lever 330 is to facilitate the user to apply a force thereto to drive the adjusting member 320 to rotate relative to the fixing member 10.

[0038] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present invention.
