A connection device includes a base and a bracket. The base includes an upper feature, a lower feature, and a middle wall disposed between the upper and the lower features. The middle wall includes a guiding structure and a position-limiting structure that define a moving space therebetween. The bracket is configured to be movably mounted on the base and includes an upper portion, a lower portion, and a middle portion disposed between the upper and the lower portions. The middle portion includes an elastic portion configured to be mounted in the moving space. The upper and the lower portions of the bracket are configured to be mounted to the upper and the lower features of the base respectively.

A cabinet is provided, which is adapted to receive a device. The cabinet includes a plurality of first pillars, a plurality of second pillars, a plurality of track units, and two sliders. Each track unit is bridged between one of the first pillars and one of the second pillars. The sliders are disposed on two sides of the device, wherein the sliders are slidably connected to the track units. Each track unit includes a first connection base and a track portion. The first connection base is disposed on one end of the track portion. The first connection base includes a first connection side, a first base side, and a second base side. The first connection side is located between the first base side and the second base side. The first connection side is connected to the first pillar.

A drawer rail includes a first rail to be fixed to a drawer, and a second rail to be arranged on rail of a drawer pull-out guide. The first rail and the second rail are to be connected to one another by sliding onto each other. The first rail and the second rail are locked to one another by a locking element, with the locking element being pre-stressed by a force of a force storage member in a direction of a locking position. The locking element is arranged on the second rail and is configured to be pivoted, upon sliding the first rail onto the second rail, about a horizontally extending axis in the mounted position, starting from the locking position, against a force of the force storage member in a direction of the carcass rail or the central rail of the drawer pull-out guide into an unlocking position.
