The present invention relates to a sliding rail assembly, which has an operating device with a push rod for pushing a first stopper along a concave surface of the intermediate rail, so the first stopper does not block a first side portion of a positioning feature of the outer rail.
Generally, in the sliding rail assembly used in the server, there is a stopper on the intermediate rail, so that when the intermediate rail extends along the outer rail, the intermediate rail forms a temporary lock with the outer rail through the stopper. When the inner rail is received in the intermediate rail, the inner rail will push the stopper to release the locked state of the intermediate rail and the outer rail. However, when the server is being repaired, it will be removed together with the inner rail. At this time, the intermediate rail cannot be received into the outer rail.
The present invention has been accomplished under the circumstances in view. It is therefore the main object of the present invention to provide a sliding rail assembly, which has an operating device movably connected to the outer rail with a push rod thereof used to push a first stopper along a concave surface of the intermediate rail, so that the operator can easily release the locked status of the intermediate rail and the outer rail with the operating device.
It is another object of the present invention is to provide a sliding rail assembly, wherein the push rod and the first stopper of the operating device are hidden in the concave surface of the intermediate rail, and the push rod directly pushes the first stopper so that there is no linkage structure between the push rod and the first stopper, which can reduce the manufacturing cost, avoid interlocking failure, and help to thin the slide rail assembly.
For achieving above-mentioned objects, the technical means that the present invention adopts comprises: an outer rail comprising at least one positioning feature; an intermediate rail displaceable relative to the outer rail and comprising a concave surface located on a back side thereof and facing the at least one positioning feature; a first stopper pivotally connected to the concave surface and being able to correspond to a first side portion of the at least one positioning feature; and an operating device movably connected to the outer rail and comprising a push rod that is placed in the concave surface and located on one side of the first stopper, so that when the push rod of the operating device pushes the first stopper along the concave surface, the first stopper is prohibited from blocking the first side portion of the positioning feature.
According to the aforementioned features, the side of the first stopper forms a first slope, and the push rod has a second slope corresponding to the first slope.
According to the aforementioned features, there is a limiting member on the outer rail, and a limiting hole on the operating device, and the limiting hole can be displaced relative to the limiting member.
According to the aforementioned features, the outer rail is provided with an operating hole, and the operating device has an operating portion and an actuating portion extending from the operating portion and displaceable relative to the operating hole, and the push rod is combined with the actuating portion.
According to the aforementioned features, the present invention further comprises a second stopper and an elastic member, wherein the second stopper is pivotally connected to the concave surface and corresponds to the second side portion of the at least one positioning feature; the elastic member has one end thereof connected to the first stopper and an opposite end thereof connected to the second stopper, so that the elastic member is capable of providing an elastic force to the first stopper and the second stopper.
According to the aforementioned features, the intermediate rail further comprises a first hole, a second hole and a third hole; the first stopper comprises a first stop portion located at one side thereof and displaceable relative to the first hole; the second stopper comprises a second stop portion located at one end thereof and displaceable relative to the second hole; the elastic member is located in the third hole for displacement.
According to the aforementioned features, the first stopper further comprises a first hook portion formed on an opposite side thereof and located at the third hole and connected to one end of the elastic member; the second stopper further comprises a second hook portion formed on an opposite end thereof and located at the third hole and connected to an opposite end of the elastic member.
According to the aforementioned features, the present invention further comprises an inner rail displaceable relative to the intermediate rail, the intermediate rail further comprises a fourth hole, and the second stopper further comprises a pushing portion located on a side end thereof and extending from the fourth hole to an opposing front side of the intermediate rail, so that the pushing portion can be pushed to displace relative to the inner rail.
According to the aforementioned features, the outer rail further comprises a positioning seat and a positioning hole, and the positioning seat is fixed to a back side of the outer rail; the at least one positioning feature is formed by bending the positioning seat, and is placed in the positioning hole to protrude to an opposing front side of the outer rail.
According to the aforementioned features, the outer rail further comprises a starting member, and the first stopper comprises a starting surface so configured that when the starting surface abuts against the starting member, the first stopper is started.
According to the aforementioned features, the first stopper further comprises a first locking groove corresponding to the first side portion of the at least one positioning feature; the second stopper further comprises a second locking groove corresponding to the second side portion of the at least one positioning feature.
Based on the aforementioned technical means, the operating device is movably connected to the outer rail, and the first stopper is pushed along the concave surface of the intermediate rail by the push rod of the operating device, and the push rod of the operating device and the first stopper are both hidden in the concave surface of the intermediate rail, and the push rod is used to directly push the first stopper, so that there is no interlocking structure between the push rod and the first stopper. It not only makes it easy for the operator to use the operating device to release the locked state of the intermediate rail and the outer rail, but also reduces manufacturing costs, avoids linkage failure, and helps to thin the slide rail assembly.

As above, the outer rail 10 is provided with an operating hole 13, and the operating device 40 comprises an operating portion 43 and an actuating portion 44 extending from the operating portion 43. The actuating portion 44 can be displaced relative to the operating hole 13, so the actuating portion 44 is located in the operating hole 13. The push rod 41 is combined with the actuating portion 44. As shown in

As above, the intermediate rail 20 is provided with a first hole 22, a second hole 23 and a third hole 24. One side of the first stopper 30 forms a first stop portion 32 and one end of the second stopper 50 forms a second stop portion 51. The first stop portion 32 can be displaced relative to the first hole 22. The second stop portion 51 can be displaced relative to the second hole 23. The elastic member 60 is located at the third hole 24 for displacement. Therefore, the first stop portion 32 is located in the first hole 22 and the second stop portion 51 is located in the second hole 23. The other side of the first stopper 30 forms a first hook portion 33. The first hook portion 33 is located at the third hole 24 and connected to one end of the elastic member 60. The other end of the second stopper 50 forms a second hook portion 52. The second hook portion 52 is located at the third hole 24 and connected to the other end of the elastic member 60, but not limited thereto.
