Slide rail assembly and its slide rail kit

technical field

The invention relates to a sliding rail, in particular to a reliable sliding rail assembly.

Background technique

1 and 2 show a slide rail 100 in the prior art, and the slide rail 100 has a longitudinal length. A first stopper 102 , a second stopper 104 , a first operation member 106 and a second operation member 108 are disposed on the slide rail 100 . Wherein, the first stopper 102 and the second stopper 104 are pivotally connected to the slide rail 100 through a first shaft A1 and a second shaft A2 respectively, so that the slide rail 100 is relatively opposite to the other slide rail 101 ( As shown in FIG. 2 ), when it is in a predetermined position (such as an extended position), the front and rear of a stopper B of the other slide rail 101 can be blocked by the second stopper 104 and the first stopper 102 The two ends are used to prevent the slide rail 100 from being displaced from the predetermined position to the opening direction D1 or the retracting direction D2.

Further, the first operating member 106 and the second operating member 108 can respectively be used to drive the first blocking member 102 and the second blocking member 104 to no longer be in contact with the blocking portion B of the other sliding rail 101 block. Wherein, the structural configuration relationship of the first operating member 106 driving the first blocking member 102 is substantially the same as that of the second operating member 108 driving the second blocking member 104. For example, as shown in FIG. 2, the first A driving portion 110 of the operating member 106 has only a single height T, therefore, if the driving portion 110 of the first operating member 106 and a corresponding portion 112 of the first blocking member 102 are caused by external force or unexpected factors One of them is deformed or shifted relative to the other, so that excessive or unexpected lateral tolerance exists (for example, the driving portion 110 of the first operating member 106 is deformed or shifted, or the first stopper 102 offset to a predetermined lateral direction K), the contact depth (for example, lateral contact depth) of the driving portion 110 of the first operating member 106 and the corresponding portion 112 of the first stopper 102 may be reduced, so that The first operating member 106 may not be able to smoothly drive the first blocking member 102; The operating member 106 cannot drive the first blocking member 102 , thus causing the problem of driving failure.

However, as market demands vary, how to develop a different and reliable slide rail product has become an issue worth discussing.
