Drop-proof positioning mechanism for sliding door of furniture

Abstract

A drop-proof positioning mechanism for a sliding door of furniture comprises a drop-proof positioning device which comprises a support base, a rotating wheel and a drop-proof element, wherein the rotating wheel is arranged on the support base in a rolling manner; and the drop-proof element is rotationally arranged on the support base. The drop-proof positioning mechanism is characterized in that a rotating shaft part and a positioning match part are arranged between the drop-proof element and the support base, an auxiliary action part is arranged on the support base, the drop-proof element is rotationally positioned on the support base step by step by virtue of interaction between the rotating shaft part and the positioning match part and is limited on the auxiliary action part when rotationally positioned step by step in at least one direction, and the axis for rotational step-by-step positioning of the drop-proof element is substantially parallel to the rolling axis of the rotating wheel. Owing to the structural improvement, the drop-proof positioning mechanism has the characteristics of simple and reasonable structure, reliable performance, convenient assembly and disassembly, convenient operation, long service life, high member connection compactness, attractive appearance, steady, smooth and safe opening and closing process, and the like, and the practicability is high.

Description

technical field [0001] The invention relates to an anti-off positioning mechanism for sliding doors of furniture. Background technique [0002] Chinese patent CN2803114Y disclosed on August 9, 2006 an automatic opening device for drawer slide rails. The sliding hook is provided by the chute of the fixed seat connected to the slide rail of the cabinet body, and is locked on the drawer. The linkage of the linkage rod of the slide rail and the elastic return force of the elastic element cooperate with the positioning axis of the rocker pivoted by the fixed seat and the introduction channel, catch channel and export support groove on the back of the slide hook. It is said that the guide of the channel and the outlet channel can achieve the automatic opening function of the drawer after being pressed; in addition, when the drawer is to be opened, the drawer must be pressed so that it slides inward for more than a certain distance, so that the automatic opening can be achieved.
