A trolley assembled by a snap-fit structure is provided. The trolley comprises a first carrying basket, a second carrying basket, a third carrying basket each having a carrying space, and an assembly support frame arranged at both sides of the first, second and third carrying baskets. The carrying baskets are respectively provided with a snap-fit assembly component for assembling onto or disassembling from the assembly support frame. The assembly support frame is provided with a clamping groove which is matched with corresponding support crossbar for a snap-fit assembly or disassembly. The disclosed trolley has a simple structure but high structural stability and can be assembled arbitrarily in a snap-fit manner and disassembled into different components which then be receipted without tools. Moreover, the disclosed trolley is convenient for packaging, storage and transport, and has strong applicability and reduced usage cost.

A storage solution uses wire shelves where the width of the wire shelves can be customized by a user by adding one or more central members between two end members. Thus, the shelving can be installed in one cabinet having a first width, and moved, if desired, to a cabinet of a different width by adding or removing central members from the shelf. Further, a manufacturer can provide a variety of shelf sizes by simply varying the number of central members that are provided. The shelving may be attached at each end to a slide to permit one or more shelves to extend outward from the inside of a cabinet.

Rail assemblies on either side of a shelf each include a rail reciprocated to a slide adjustable from a rail-locking position to a post-locking position. The slide is configured to restrain the rail from reciprocating longitudinally relative to the slide, when the slide occupies a rail-locking position and the rail occupies a stowage position relative to the slide. The slide is configured to enable the rail to reciprocate longitudinally relative to the slide and to releasably secure a rack post, when the slide occupies the post-locking position.

A rack having scalability and compatibility may be configured to reversibly adjusted to be reversibly configured to support various computerized equipment having various sizes and power supply schemes without adjusting an outer volume boundary of the rack and without replacement of the rack. The rack may include a main frame and an additional frame. The main frame may structurally support computerized equipment having a particular dimension that is a first size within an enclosure that is a first enclosure at least partially defined by the main frame. The additional frame may reversibly couple with the main frame to adjust the enclosure to be a second enclosure at least partially defined by the at least one additional frame to reversibly configure the main frame to store computerized equipment having the particular dimension that is a second size that is different from the first size.

A bracket mechanism includes a connecting wall and a mounting device. The mounting device and the connecting wall are movable relative to each other to be in a locking state or an unlocking state. The mounting device includes at least one mounting member. When the mounting device and the connecting wall are in the locking state, the at least one mounting member is adjacent to the connecting wall to be closed relative to each other. When the mounting device and the connecting wall are in the unlocking state, the at least one mounting member is away from the connecting wall to be opened relative to each other.

A bracket mounting structure includes a bracket, a base, a connecting member, an elastic member, and a mounting member. The bracket includes a longitudinal wall. The base is arranged adjacent to the longitudinal wall and includes a first space and a second space. The connecting member is mounted in the first space and includes a first portion, a second portion, and a through hole arranged in the first portion and the second portion. At least one of the first portion and the second portion has a screw thread feature. The elastic member is received in the first space and is configured to apply an elastic force to the connecting member. The mounting member is mounted in the second space.
