Description

Double-slider damping device with self-rescue function

Technical Field

The invention relates to the field of furniture, in particular to a double-slider damping device with a self-rescue function.

Background

The damping slide rail is one of slide rails, and means that a sound attenuation and buffering effect which utilizes the buffering performance of liquid and has an ideal buffering effect is provided. The slide rail is fast, easy and excellent, and automatic selection is realized by recording. It relies on a completely new technique to adapt the closing speed of the drawer. When the drawer is closed to the last distance, the speed can be reduced by hydraulic pressure, the impact force is reduced, and the comfortable effect during closing is achieved. Even if force is used for pushing the drawer, the drawer can be closed softly, and the perfect and gentle movement is ensured. The buffer device comprises a fixed rail, a middle rail, a movable rail, a ball, a clutch and a buffer, wherein the buffer is arranged in the fixed rail; the buffer comprises a piston rod, a shell and a piston, wherein the piston is provided with a through hole and a hole, and when the piston rod drives the piston to move, liquid can flow to the other side from one side through the through hole, so that the buffer plays a role in buffering and damping. It is commonly used for the push-pull movement of drawers.

The soft and silent feeling of the household makes the household more temperature-sensitive, comfortable and comfortable, the slide rail product produced by the slide rail production process is delicate in working, and the slide rail product is more and more popular with domestic people by matching with a durable hydraulic cylinder. It relies on a brand-new technique to adapt to the closing speed of drawer, the product passes through hydraulic cushion technique, make the drawer slowly close by oneself when still having a distance from the drawer limit, reduce the impact force, form the comfortable effect when closing, the assembly damping slide rail makes furniture more high-grade, reduce the impact force and form the comfortable effect when closing, even more guaranteed under long-time use, also need not to maintain, but most is the single slider, can't accomplish when the poor slider that cuts of slip effect drops and save oneself.
