Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] see Figure 1-3 , the three sections hide slide rails synchronously, including movable rail 1, middle rail 2, fixed rail 3 and damping mechanism 4. An upper rack 5 and an upper roller cage 6 with rollers are arranged between the movable rail 1 and the middle rail 2; a split lower roller cage 7 with rollers is arranged between the middle rail 2 and the fixed rail 3, and its surface There is a rack; a gear assembly 8 is meshed between the upper rack 5 and the lower roller cage 7, and the gear assembly 8 controls the synchronous or misplaced operation of the movable rail 1 and the middle rail 2 according to the magnitude of the force; the movable rail 1, the middle rail 2 and the damping mechanism 4 are assembled on the fixed rail 3 respectively. This slide rail is symmetrically arranged on both sides in the cabinet cavity, and it is fixed through...

Abstract

The invention discloses a three-section synchronous hidden slide rail, which comprises a mobile track, a middle track, a fixed track and a damping mechanism. The three-section synchronous hidden slide rail is characterized in that an upper rack and an upper roller holder provided with a roller are arranged between the mobile track and the middle track; a split lower roller holder provided with a roller is arranged between the middle track and the fixed track, and a rack is arranged on the surface of the lower roller holder; a gear component is engaged between the upper rack and the lower roller holder, and the gear component controls the mobile track and the middle track for synchronous or staggered operation according to the magnitude of acting force; the damping mechanism is assembled on the fixed track. According to the three-section synchronous hidden slide rail, a gear A and a gear B of the gear component are tightly matched and assembled with a polygonal hole through a polygonal column, when the acting force is smaller than a constant value, the synchronous operation is implemented; when the acting force is greater than the constant value, the polygonal hole is expanded, the two gears slip and rotate, and the mobile track and the middle track run separately. The gear component, the upper rack and the lower rack are guaranteed to be matched at correct positions, so that the slide rail can be continuously used, and thus the racks and the gears are difficult to damage.

Description

technical field [0001] The invention relates to a drawer slide rail, in particular to a three-section synchronous hidden slide rail. Background technique [0002] Chinese Patent Document No. CN2011201145550 disclosed a slide rail type drawer on June 04, 2008, including a drawer, a slide rail and a box body. The three-section slide rail includes the upper rail, the middle rail and the bottom rail. The middle rail has two installation support planes, namely the upper installation support plane and the lower installation support plane. The upper rail is set on the upper installation support plane of the middle rail. The rail is set on the lower installation support plane, the upper rail rack and pulley frame is set on the lower part of the upper rail, the bottom rail rack and pulley frame is installed on the upper part of the bottom rail, and a gear is meshed between the upper rail rack and pulley frame and the bottom rail rack and pulley frame ;Set a resetter at the end of th...
