At this time, the third rail 26 can continue to be displaced in the opening direction D1.

As shown in FIG. 10 to FIG. 13 , the third rail 26 continues to be displaced in the opening direction D1. During the process, since the elastic portion 146 of the latching member 140 has the ability to flex elastically, when the third rail 26 has not been displaced to a position, the elastic portion 146 is pressed against the second rail 24 and A state of elastic pressure accumulation between the third rails 26 (as shown in FIGS. 10 and 12); until the third rail 26 continues to be displaced to the position, the elastic portion 146 releases the elastic force to cause the latching member The positioning portion 142 of the 140 can enter the opening 152 of the first longitudinal portion 32 of the third rail 26 and correspondingly engages against an opening wall surface 153 of the opening 152. At this time, the third rail 26 is in an open position (as shown in FIGS. 11 and 13).

As shown in FIG. 14 to FIG. 16, when the third rail 26 is in the open position and the operator wants to detach the third rail 26 from the second rail 24, the operator only needs to remove the third rail. The opening 152 of the 26 applies a force F1 (as shown in FIG. 16) to the elastic portion 146 of the latching member 140, so that the positioning portion 142 of the elastic portion 146 is separated from the opening 152 and no longer corresponds to the opening wall surface 153. The operator can withdraw the third rail 26 to a disassembly direction D2 (as shown in FIG. 15) to detach the third rail 26 from the second rail 24.

As shown in FIGS. 17A-17D, after the third rail 26 is detached, the operator can further detach the second rail 24 from the first rail 22. The operator can apply a force F2 (such as FIG. 17B) to pull the operating portion 128 of the release member 120 so that the movable portion 122 of the release member 120 can be displaced relative to the limiting member 118 by the longitudinal groove 126. Accordingly, the untwisting portion 124 of the release member 120 is interlocked so that the untwisting edge 136 can correspondingly drive a portion of the swinging member 86 (for example, the extended side portion 94) (at this time, the flexible body 130 is subjected to The force of the stopper 138 is in a curved state, and the leg portion 92 of the swinging member 86 is displaced to be separated from the concave portion 114 of the second rail 24 again. In this state, the operator can withdraw the second rail 24 in a disassembly direction D3 to detach the second rail 24 from the first rail 22 (as shown in Fig. 17C). And when the operator stops applying force F2 After the operation portion 128, the flexible body 130 drives the release member 120 to return to the initial state again (as shown in FIG. 17D).

As can be seen from FIG. 14 to FIG. 17, the third rail 26 and the second rail 24 of the slide rail assembly can be detached, so that the operator can replace the chassis (for example, the server chassis) or replace the rail assembly. , maintenance and other operations.

As shown in FIG. 18A to FIG. 18C, when the operator wants to displace the slide rail assembly from the above-mentioned open position (as shown in FIG. 11) to a folding direction D4, the operator can press the same. The elastic portion 146 of the latching member 140 (as in the state of FIG. 16), and the third rail 26 is displaced to the folding direction D4, so that the second rail can be pushed by the inclined portion 36 of the third rail 26 24, the third rail 26 and the second rail 24 can be folded relative to the first rail 22. And when the second rail 24 is displaced to a position, the guiding slope 150 of the hook portion 148 of the third rail 26 can correspondingly push the contact portion 110 of the actuating member 100 to make the contact of the actuating member 100 The portion 110 is supported by the guiding slope 150 away from the retaining wall 84 of the guiding portion 78 of the first rail 22 (as shown in FIG. 18B); and the inclined surface 116 of the second rail 24 pushes the foot of the swinging member 86 92, the foot portion 92 is offset away from the recess 114 (as shown in Fig. 18C). Accordingly, the contact portion 110 of the actuator 100 can be again hooked by the hook portion 148 of the third rail 26, so that the third rail 26 and the second rail 24 are folded with the first rail 22. (This section can also refer to Figure 9A).
