Description
Technical Field
The utility model particularly relates to a synchronous multistage slide rail, in particular to a synchronous slide rail driven by a single-side rope.
Background
The synchronous sliding rail generally refers to a multistage sliding rail mechanism at least comprising an upper rail, a middle rail and a lower rail, wherein the upper side and the lower side of the common middle rail are respectively connected with the upper rail and the lower rail in a rolling way through balls, the friction force between the lower rail and the middle rail is often high in the using process, when the lower rail and the middle rail do not relatively displace, the upper rail slides on the middle rail, the problem that the middle rail extends out is easy to occur particularly when the upper rail is closed, for example, when the upper rail is arranged on a drawer, the lower rail is arranged on a cabinet body of the drawer, when the drawer is retracted from a fully-opened state, the friction force between the middle rail and the lower rail is high, when the drawer is closed, the upper rail is firstly taken to extend into the cabinet body, the position of the middle rail is not changed, but the middle rail is in an outward-extended state because the upper rail is lack of middle rail support, when the drawer is closed, but the drawer is communicated with the upper rail, drawer gravity can't evenly transmit for the lower rail through the middle rail, leads to the upper rail to produce the dislocation with the middle rail easily, directly leads to the upper rail to directly break away from with the middle rail even, perhaps the drawer has closed, but the middle rail still leaks the problem in the drawer outside.
Therefore, to this kind of problem, we need a lazytongs that can drive well rail and last rail and pull out in step and the closure returns, although there is the synchronous slide rail mechanism of some rail block guide formulas in the existing market, but the structure is complicated, lead to a plurality of slide rail sizes big, the installation space who occupies is big, and because the guide effect of slide rail block produces certain noise problem easily, some embedded chamber door cabinet body installation environment, to the width size of guide rail itself, installation clearance and laminating degree are higher and higher, some slide rail devices that have lazytongs, both sides all set up the locating part, lead to the laminating that the slide rail both sides can not be fine.
Based on this, a multi-stage synchronous sliding rail device which has lower cost and smaller installation clearance and can realize synchronous pulling-out and closing retraction is needed.
