Description

Technical Field

[0001] This utility model relates to the field of rebound mechanism technology, and in particular to a rebound mechanism with adjustable drawer panel closing gap. Background Technology

[0002] Chinese Patent Document No. CN219306314U disclosed a drawer slide rebound device and a three-section slide using the same on July 7, 2023. The device includes a fixed base, a rebound base, a locking pin, an inner rail pin, and a spring. The fixed base is provided with a slide groove and a compression groove for loading the spring. The slide groove has a hollowed-out travel groove, and the end of the travel groove extends to the end of the slide groove. The locking pin is movably installed at the front end of the slide groove. The rebound base is provided with a slider and a compression pin for compressing the spring. The slider is provided with a locking block and a guide groove surrounding the locking block. The inner rail pin is movably installed at the front end of the slider. The slider is slidably assembled into the slide groove. The inner rail pin passes through the travel groove, and the compression pin is inserted into the compression groove. After the drawer is closed, there needs to be a certain amount of travel between the panel and the cabinet. If the gap between the panel and the cabinet is too small, the drawer will not have enough space to move backward when the drawer is pressed, thus failing to trigger the rebound opening. In addition, when the user presses the drawer, they may only press one side of the drawer, which may result in the other side of the drawer moving only a small distance backward, also failing to trigger the rebound opening.

[0003] Therefore, further improvements are necessary. Utility Model Content
