Drawer slide rail device capable of automatic buffer recovery

Abstract

The invention provides a drawer sliding rail device capable of automatically returning in a buffering mode. The drawer sliding rail device not only realizes the automatic returning function of a drawer sliding rail, but also can meet the requirement that the gap between a fixed rail and the sliding rail be small. The drawer sliding rail device comprises the fixed rail, the sliding rail and the automatic returning device; the fixed rail is fixedly installed on the inner side wall of a cabinet body; the sliding rail is fixedly installed on the outer side wall of a drawer; the sliding rail is installed inside the fixed rail and can slide back and forth along the fixed rail; the sliding rail is provided with a shifting component, wherein the shifting component drives the automatic returning device to move when the sliding rail slides along the fixed rail so as to realize the drawer opening / closing process. The drawer sliding rail device is characterized in that the automatic returning device is installed on one outer side edge of the bottom of the fixed rail through a positioning plate, the shifting component is installed on the outer surface of the sliding rail, the shifting end of the shifting component extends out of the outer surface of the sliding rail, and the shifting end of the shifting component can be clamped with the automatic returning device.

Description

Technical field [0001] The invention relates to the field of sliding rail devices, in particular to a drawer sliding rail device with an automatic buffer recovery function. Background technique [0002] In the existing drawer slide rail structure, most of the drawer slide rails do not have the automatic recovery function, which causes the user to apply thrust throughout the entire process to completely close the drawer; when the user exerts too much force, it is easy to cause the drawer and the cabinet Part of the body collides or even the drawer rebounds. If you operate this way for a long time, the cabinet is easily damaged; and when the force is too small, the drawer cannot be completely closed. Especially for the drawer in the refrigerator, it is easy to cause the storage in the cabinet and the surrounding gas Contact, can not meet the preservation requirements. Although a small number of drawer slide rails are equipped with automatic recovery devices, most of their automati...

Problems solved by technology

[0002] In the existing drawer slide rail structure, most of the drawer slide rails do not have the function of automatic recovery, so that the user needs to apply a pushing force all the way to completely close the drawer; when the user applies too much force, it is easy to cause the drawer and cabinet Body part collision or even drawer bounce phenomenon, long-term operation in this way, the cabinet body is very easy to damage; and when the force is too small, the drawer cannot be completely closed, especially for the drawer in the refrigerator, it is easy to cause the storage in the box and the surrounding gas Contact, can not meet the preservation requirements

Although a small number of drawer slide rails are provided with automatic recovery devices, most of the automatic recovery devices are installed inside the fixed slide rails, such as the Chinese invention patent with the publication number CN101994758, which discloses a sliding device with an automatic closing part. The self-closing part can realize the automatic closing function of the sliding track relative to the fixed track, but because its self-closing part is integrally installed in the fixed track, it cannot adapt to the situation where the gap between the fixed track and the sliding track is small
