Description

Technical Field

[0001] The invention relates to the technical field of drawer installation, in particular to an adjustment mechanism with a drawer self-adaptation function. Background Art

[0002] At present, drawers are equipped with slide rails. No matter the slide rails are two-stage or three-stage, generally, fixed rails are installed on the cabinet body, and movable rails are installed on the drawer. The relative sliding of the movable rails and fixed wheels is used to realize the opening and closing movement of the drawer.

[0003] The slide rail is generally installed with the drawer by using a connecting device. The traditional connecting device is installed with an adjustment assembly. The traditional adjustment assembly includes an adjustment fixing seat and an adjustment connecting seat. The adjustment fixing seat is installed on the drawer. The adjustment connecting seat is positioned and slides up and down on the adjustment fixing seat. The movable rail of the slide rail is buckled on the adjustment connecting seat by a buckle. When the drawer is assembled, the adjustment connecting seat is adjusted to move upward or downward to adjust the installation height of the drawer.

[0004] However, the traditional adjustment assembly generally has the following shortcomings in practical applications:

[0005] 1) The structure of the adjustment assembly is relatively complex and has poor stability. It is easy to produce deviations from the assembly of the slide rail and the drawer, reducing the precision and even failing to open and close normally, affecting the normal use of the drawer.

[0006] 2) When the height installation position of the drawer is adjusted by the adjustment assembly, a gap is easily generated between the adjustment connection seat and the movable rail, which reduces the stability and load-bearing strength of the slide rail connection, easily causes the slide rail to deform, and reduces the quality of use of the slide rail.

[0007] 3) The adjustment assembly is in hard contact with the tail hook of the movable rail of the slide rail. When the drawer is installed with deviations, it is easy to produce impact noise, affecting the silent effect of the drawer closing. Summary of the invention

[0008] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an adjustment mechanism with a drawer adaptive function. The mechanism has a simple structure, can adjust the horizontality of the drawer, and has an adaptive front and rear fine-tuning function, thereby improving assembly precision, eliminating impact noise, enhancing structural stability, and ensuring the normal use of the drawer.
