There is an arc at the end of the inner rail of the slide rail Groove. When the inner rail of the slide rail enters the end, the inner rail of the slide rail enters the anti-tilt device along the guide groove. The sliding column is released from the bayonet of the slideway. At this time, the stretched spring will automatically move the slider and the sliding seat to the end together due to the elastic force. The effect of gravity automatically restores to the original state; the process from the arc-shaped groove to release the sliding column from the bayonet of the slideway to the automatic return of the slider to the original state can also be said to be a self-locking process. When the inner rail of the slide rail slides out of the anti-tilt device along the guide groove, the arc-shaped groove makes the sliding column re-locked on the bayonet of the slideway. During this process, the sliding seat and the sliding block also slide along, and the slope of the sliding block will Apply force on the tapered slope of the pin on the upper side of the base to push the pin on the upper side of the base to the upper end, and the pin on the lower side of the base has reserved a movable space, so the slider cannot be pushed up. Therefore, the latch on the lower side of the base will remain motionless and prevent the latch at the other end of the connecting rod 8 from being lifted up; when the sliding column is stuck on the bayonet of the slideway, the spring is in a stretched state again.

In actual furniture, there are generally many layers of drawers, and this anti-tilt device will also be installed on the drawers of each layer at this time; The latches on the upper side of the base are connected to each other through connecting rods. When one drawer is opened, the other drawers cannot be opened, thus realizing the interlocking function; in other words, only one drawer can be opened at a time. This can prevent the cabinet from tipping over when the drawer is pulled out with too much load. When making base, can adopt plastic material to make.

This device can not only realize the self-locking function of the drawer, but also realize the interlocking function between the drawers. This prevents the cabinet from tipping over when the drawer is overloaded. The structure is simple and practical, and the operation is convenient.
