Description

Slide rail assembly

technical field

The invention relates to a slide rail assembly, in particular to a slide rail assembly with a supporting mechanism between two slide rails.

Background technique

Generally speaking, the slide rail assembly is mainly used to provide a load installation, so that the load can be displaced relative to the other slide rail through one slide rail of the slide rail assembly. In some current slide rail assembly technologies, a ball device can be used between the two slide rails to facilitate mutual displacement.

In U.S. Patent No. 7,370,920B2 invented by Wang et al., Fig. 2 discloses that the inner rail 16 extends beyond the end of the middle rail 14, wherein the inner rail 16 is provided with a plurality of J-shaped holes spaced apart (the drawing is not labeled ). A ball retainer 22 is disposed between the inner rail 16 and the middle rail 14 , and a plurality of balls 24 are disposed thereon. The length of the ball retainer 22 is shorter than that of the inner rail 16 , and FIG. 4 reveals that the ball retainer 22 corresponds to the position of the J-shaped hole of the inner rail 16 . This J-shaped hole setting is mainly for the standoff on one side of the chassis (chassis) to be installed in the J-shaped hole of the inner rail 16 in a drop-in installation manner. Therefore, because the ball retainer 22 interferes with the installation of the chassis mount, so the ball retainer 22 disclosed in this case is very short, and does not exceed the position of the last J-shaped hole of the inner rail 16.

Apparently, the design of this case will affect the support ability provided by the ball cage 22 to the inner rail 16 and the middle rail 14 . Thus, as shown in Figure 6 of this case, this case discloses that two separate protrusions 26 are provided at the end of the inner rail 16, and a support bar 34, 38 is installed between the two protrusions 26 to complement The supporting capacity of the inner rail 16 relative to the middle rail 14 .
