Description

Synchronous rebound device structure

Technical Field

The utility model relates to a synchronous rebound device structure.

Background

Prior art as shown in fig. 13 to 15, the existing rebound device locking is achieved by a locking member 101 which is moved up and down by a spring. When the spring base 102 of the rebound device is pushed by the iron hook base 104 and the movable rack 103 to touch the inclined surface 105 of the locking member 101, the locking member 101 moves downward under the action of the inclined surface 105. When the slot 106 of the spring base 102 passes completely through the locking member 101, the locking member 101 automatically pops up. At this time, since the spring base 102 is under tension of the tension spring, a certain noise is generated in the case that the locker 101 moves up and down when the drawer is closed and locked.

Meanwhile, as shown in fig. 14. When the iron hook base 104 of the rebound device moves leftwards under the action of the upper rail, at the moment, the iron hook base 104 pushes the movable rack 103 to synchronously move leftwards, when the bottom plane of the movable rack 103 is completely compressed downwards by the locking piece 101, and when the locking piece 101 is completely compressed downwards, the spring base 102 can reset rightwards to the initial position under the action of the tension spring. At the moment of the locking member 101 and the spring base 102, a certain noise is generated.
