Abstract
The present invention discloses a three-segment rail with an extractable outer rail including a fixing frame, an outer rail, a middle rail and an inner rail, wherein, the fixing frame, the outer rail, the middle rail and the inner rail are connected orderly. The fixing frame is connected to a machine frame through a front lock on the front end and a rear lock on the rear end, the upper side and the lower side of the fixing frame are provided with bindings, and the bindings cover the upper side and the lower side of the outer rail, and a sliding block is arranged between the inner wall of the bounding and the outer rail. One segment of the outer rail is extracted from the fixing frame and overlaps with the middle rail for bearing weight together when an over stroke of the sliding rail occurs so that the three-segment rail becomes the four-segment rail without sliding rail increase and the bearing ability is enhanced when the over stroke of the sliding rail occurs.

Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Shown in Fig. 4, the three joint rails that a kind of outer rail can be extracted out, comprise the fixed frame 10, outer rail 20, middle rail 30 and the interior rail 40 that connect successively, described fixed frame 10 is connected in frame by lock 50 and rear lock 60 before its rear and front end, described fixed frame about 10 both sides are respectively arranged with bound edge 11, described bound edge 11 is coated on described outer rail about 20 both sides, is provided with slide block 12 between described bound edge 11 inwall and outer rail 20.When slide rail overtravel is opened, extract outer rail 20 out one section from fixed frame 10, overlapping with middle rail 30, shared bears a heavy burden; Making when not increasing slide rail it become four joint rails, improving the bearing capacity of slide rail when overtravel is opened.Slide block 12 1 aspect that bound edge 11 inwall connects can reduce the frictional force between outer rail 20 and fixed frame 10, can be delivered on fixed frame 10 by the power on outer rail 20 on the other hand by slide block 12, improves bearing capacity.
As a preferred embodiment of the present invention, described fixed frame 10 comprises cross section for "] " the first framework 101 and the second framework 102 of shape, described first framework 101 is connected back-to-back with the second framework 102, second framework 102 one end connects described front lock 50, the other end connects described rear lock 60 by after-poppet 61, described first framework about 101 both sides are described bound edge 11, and described outer rail 20 is plugged in the bound edge 11 of the first framework 101 both sides.Described slide block 12 is connected to bound edge 11 inwall of upper and lower both sides, is positioned at the first framework 101 two ends.
Described first framework 101 side is provided with gear point shell fragment 13, and described outer rail 20 is provided with the gear point 21 be mated, described gear point shell fragment 13 towards slide rail opening direction opening, and tilts to outer rail 20 side.During installation, outer rail 20 is inserted in the bound edge 11 of the first framework 101, until gear point 21 is touched with gear point shell fragment 13, gear point shell fragment 13 is extruded by the gear point 21 continuing to move ahead, and after departing from gear point shell fragment 13 to gear point 21, gear point shell fragment 13 resets, now, gear point 21, due to the stop of gear point shell fragment 13, cannot move backward, realizes the effect stopped.Gear point shell fragment 13 and gear put 21 coordinate and realize instrument of exempting from and install, and have latch functions, prevent outer rail from excessively regaining, cause slide rail to lose efficacy.
Described first framework 101 side is provided with sequence lock 14, described outer rail 20 is provided with the order lock pin 22 be mated, described sequence lock 14 opening is towards slide rail closing direction, and described order lock pin 22 is connected in the lock pin chute 23 that vertical direction on outer rail 20 offers.Sequence lock 14 can make interior rail 40, middle rail 30, outer rail 20 open successively, more meets user demand.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
