Slide rail device

A rack system comprising:

• a rack;
• a carried object having a plurality of mounting members protruded from a side part of the carried object and
• a slide rail device, comprising:
• an auxiliary component mounted to the rack;
• a slide rail movably mounted to the auxiliary component, the slide rail having a side wall and an auxiliary hole, wherein a first wall section and a second wall section are bent relative to the side wall, a mounting path is formed between the first wall section and the second wall section, the slide rail is configured to mount the carried object by moving the carried object toward the slide rail with the plurality of mounting members entering the mounting path along a longitudinal direction of the slide rail to sequentially pass through the mounting path;
• a locking member pivoted to the slide rail;
• an operating member pivoted to the slide rail and configured to operatively move the locking member between a first position and a second position;
• a movable member movably mounted to the slide rail;
• and
• an engagement member mounted to the auxiliary component, the engagement member having an elastic part and an engagement part;
• wherein when the locking member is located at the first position, the locking member is configured to block the mounting member from passing through the mounting path;
• wherein when the locking member is located at the second position, the operating member is configured to abut against the locking member to hold the locking member at the second position without blocking the mounting member from passing through the mounting path;
• wherein when the locking member is located at the second position and the slide rail is moved relative to the auxiliary component from an extended position toward a retracted position, the engagement part of the engagement member passes through the auxiliary hole of the slide rail in response to the elastic force of the elastic member to block the movable member, and the movable member is moved relative to the slide rail in response to the blocking of the engagement part, in order to drive one of the locking member and the operating member to move from the second position to the first position.
