A dismountable slide rail is provided. The slide rail includes a bottom rail (20), a middle rail (30), an upper rail (40), a pulley block (50) and a buckle mechanism (60). The bottom rail (20) has a sliding rail (22) on which the middle rail (30) moves with position limit. The middle rail (30) has a left and right projecting rail (33), and there is a gap (34) at one end of the left and right projecting rail (33). At the front end of the middle rail (30) there is a front pulley (35) that rolls on the inner horizontal surface of the upper rail (40). On the both sides of the middle rail (30) there are stable pulleys (32) that roll along the medial surface of the upper rail (40). The upper rail (40) has a bottom pulley (41) that rolls under the left and right projecting rail (33) so as to drive the upper rail (40) moves with position limit relative to the middle rail (30). And at the rear of the upper rail (40) there is a back pulley (42) that rolls on the top surface of the middle rail (30). The buckle mechanism (60) includes a limit member (62) and a buckle member (61) that are set on the upper rail (40) and the middle rail (30) respectively in order to limit pull-out length of the upper rail (40). When the bottom pulley (41) reaches the gap (34), by pulling the upper rail (40) upward, the bottom pulley (41) can leave the left and right projecting rail (33) of the middle rail (30) from the gap (34) so as to make the upper rail (40) leave the middle rail (30). |
