Description

Externally hung rebound buffering random stop sliding rail device with synchronous balance function

Technical Field

The utility model relates to the technical field of furniture drawers, in particular to an externally hung rebound buffering random stop sliding rail device with a synchronous balance function.

Background

In the prior art, the drawer is a common appliance in our life, and the drawer is usually required to be matched with a sliding rail, wherein the sliding rail is also called a sliding rail, a sliding way and a hardware connecting part which is fixed on a cabinet body of furniture and is used for the drawer or a cabinet plate of the furniture to come in and go out, and the sliding rail is suitable for connecting a wooden drawer of a cabinet, furniture, a briefcase, a bathroom cabinet and the like with a drawer of the furniture of steel.

However, the existing sliding rail has the following defects:

1. the self-closing angle type sliding rail is characterized in that a section of sliding rail which is slightly inclined downwards is arranged at the rear end of the fixed rail, so that a front roller of a sliding rail arranged on the drawer automatically slides downwards under the action of dead weight when walking to the inclined section, and the drawer is ensured to be completely closed. However, when the roller of the sliding rail is pushed to the sliding end, the roller slides downwards only by the self weight of the drawer and is enabled to slide downwards by an inclined plane of 2.5-3 degrees, the sliding closing is not obvious, and the use effect is quite unsatisfactory; because the bending angle is small and the drawer cannot be self-locked, the drawer can slide out and fall off when being slightly inclined outwards; because the drawer has no self-locking function, when the desk is moved, the drawer is easy to slide out under the action of dead weight, so that the movement is inconvenient.

2. The opening device must be mounted very precisely in order to predefine the closed position of the movable furniture for an excellent panel appearance.

3. When pushing the drawer, if only one side of the drawer is pushed or the drawer is deviated from the center of the drawer, the phenomenon that the left side and the right side of the drawer are not synchronous when pushing and pulling easily occurs. The rebound type sliding rail can only be used for small drawers, and once the rebound type sliding rail is used on a large or heavy sliding rail, the sliding rail cannot be synchronously pushed due to different sliding rail forces on two sides of the action, so that the sliding rail is stressed in an unbalanced manner to be inclined and blocked, the stability is poor, the failure rate of the sliding rail is increased, and the sliding rail cannot smoothly run or cannot run.

4. Because the actions of the sliding rails at the two sides are asynchronous, the connection of the rebound actions is easy to be unstable, mutual interference exists between the parts, and the phenomenon of blocking can also occur.

5. The rebound device is easy to cause too high speed under the rebound effect, and has potential safety hazard.

With the continuous change of social development and people's thinking and behavior, many new demands are put forward on the use of various things in daily life. Therefore, the requirements on humanization and energy simplification of the functional sliding rail are higher and higher. In order to meet the demands of people on real life, it is necessary to develop a structural device with self-locking, rebound, buffering and linkage opening functions and various simple and easy installation.
