no. 1 example

[0024] see figure 1 - Figure 6 , the synchronous device of this drawer slide rail comprises two sets of slide rail assemblies arranged on the left and right cabinet side panels 18, the slide rail assembly is provided with a drawer, and the drawer is at least made up of bottom and front panel 17. The slide rail assembly is composed of a moving slide rail 1, a middle slide rail 15 and a fixed slide rail 2, and the three are slidingly connected by rolling elements. Among them, the left and right moving slide rails 1 or the fixed slide rails 2 are provided with a synchronizing device for drawers, the synchronizing device at least includes a chute seat 3 and a sliding block 4, and the sliding block 4 acts on the chute seat 3 and is set on it. There is a rack 4.1, and the chute seat 3 corresponds to the rack 4.1 to rotate and is provided with a gear 5 meshing with it, and the left and right gears 5 are connected by a rotating connecting rod 6 to realize the synchronous opening and...

no. 2 example

[0031] see Figure 7 , Figure 8 , The pushback device of the drawer slide rail is different from the first embodiment in that: the synchronizing device is arranged on the left and right fixed slide rails 2 through the connecting block 16 . Specifically, the left and right fixed slide rails 2 are respectively fixed with connection blocks 16, and the connection block 16 is provided with a synchronizing device; 4.2, and at least when the sliding arm 8 slides and stays along the track of the heart-shaped slot, it is elastically loaded on the first dial 9.1 through the elastic member 11; the sliding block 4 acts on the first dial through the convex part 4.2 at least when the drawer is opened Block 9.1, realize sliding block 4 sliding on chute seat 3.

[0032] Other unmentioned parts are the same as the first embodiment.

no. 3 example

[0034] see Figure 9 , the pushback device of the drawer slide rail is different from the first embodiment in that: the movable slide rail 1 or the fixed slide rail 2 is also provided with a drawer damping device; the corresponding damping device is on the movable slide rail 1 or the fixed slide rail The rail 2 is provided with a retaining strip 9.2. Because the damping device is a prior art, it will not be described in detail now.

[0035] Other unmentioned parts are the same as the first embodiment.

Abstract

A synchronizing device of drawer sliding rails comprises two sets of sliding rail assemblies arranged on a cabinet left side plate and a cabinet right side plate, wherein a drawer is arranged on the sliding rail assemblies and is at least composed of a bottom and a front panel, each sliding rail assembly is at least composed of a movable sliding rail and a fixed sliding rail, a drawer synchronizing device body is arranged on the left movable sliding rail and the right movable sliding rail or the left fixed sliding rail and the right fixed sliding rail and at least comprises a sliding groove base and a sliding block, the sliding block acts on the sliding groove base, racks are arranged on the sliding block, gears mutually meshed with the racks are rotationally arranged on the sliding groove base and correspond to the racks, and the left gear and the right gear are connected through a rotating connecting rod to achieve synchronous opening and closing of the left sliding rail assembly and the right sliding rail assembly; a poking block is arranged on the movable sliding rails or the fixed sliding rails, and a stopping part is arranged on the sliding block and is loaded on the poking block through elasticity of an elastic part at least when a suspending distance A is preserved between the front panel and the cabinet side plates; the sliding block acts on the poking block through the stopping part in at least one segment of travel when the drawer is opened or closed so that the sliding block can slide on the sliding groove base.

Description

technical field [0001] The invention relates to a drawer slide rail, in particular to a synchronizing device for the drawer slide rail. Background technique [0002] Chinese patent document CN101316530A disclosed a drawer on December 3, 2008, which can move from a position in the furniture to a pull-out position in front of the furniture through a pull-out guide device relative to the furniture, wherein the drawer is in the opposite position. There is at least one toothed wheel on each of the opposite sides, which meshes with a toothed rack fixed on the furniture body and is connected with a toothed wheel on the opposite side, each toothed rack can be lengthened via a deflectable rod , thereby also ensuring that the drawer is guided by the gears in the pulled-out position, a deflectable rod can be disengaged from the engaged gears so that the skewed position of the drawer can be corrected, thus ensuring that the drawer is guided by the gears throughout its travel. The struc...
