The disclosure relates to the technical field of cabinet splicing and specifically relates to a quick-splicing structure and a cabinet. A quick-splicing structure for quick connection between two surfaces includes at least one group of slidably fitting components and a plurality of groups of locking components. The slidably fitting components include a first member and a second member that are slidably fitted and disposed on the two surfaces. The locking components include a first fastener and a second fastener that are fitted to be locked and respectively disposed on the two surfaces, and the plurality of groups of locking components and the slidably fitting components are arranged in an alternating manner in a locking direction. The disclosure further provides a cabinet including the quick-splicing structure. A plurality of the cabinets are connected horizontally and/or vertically through the quick-splicing structure.

Described herein are various coupling systems to be used with storage units that are selectively coupled and decoupled. The coupling systems may be used with storage units that are stackable and/or transportable, thus allowing the storage units to function well within a large stationary environment, such as a basement, and also for a subset of the storage units to be selected and easily moved to another location.

A power distribution device that couples to storage units is provided. The power distribution device a battery charger that indirectly charges batteries, such as for personal electronic devices. The device includes a top panel with a recess that receives the personal electronic devices. The device also includes interface components to couple the device to a modular tool storage unit.

A tool box assembly includes a first body, a first receiving portion, two first locking units, a second body, three second locking units, a third locking unit, and a fourth locking unit. The first receiving portion is provided with a first receiving recess and an opening. Each of the first locking units is provided with a projecting piece, at least one first locking portion, and a first restriction portion. Each of the second locking units is provided with a second receiving recess and a second locking portion. The third locking unit is locked on the first locking units. The fourth locking unit is mounted on the first receiving portion and locked on one of the second locking units. The fourth locking unit is driven to be detached from the second locking units.

A storage container with various aspects is described herein. The storage container may have cleats or cleat receptacles to interact with other storage containers and/or accessories. The storage container may also include rails for attachment of various accessories. Some versions of the storage container may further include telescopic uprights connected to a handle. Many of the versions of the storage containers may further include wheels for transporting the storage containers and their contents.

A tool container system includes a first tool container and a second tool container. The first tool container has a first base, a first cover pivotably attached to the first base by a first hinge portion, a first base locking member coupled to the base, a first cover locking member coupled to the first cover, and a first latch coupled to the first base and moveable between a first unlocked position in which the first cover is movable relative to the first base between a closed position and an open position, and a first locked position in which the first latch engages the first cover locking member and the first cover is locked to the first base in the closed position. The second tool container is stackable on the first cover of the first tool container and having a second locking member. When the second tool container is stacked on the first tool container, the second tool container is lockable to the first tool container when the first latch is moved to the first locked position to engage both the first cover locking member and the second locking member.

A tool accessory holder for use with a tool accessory case and configured to couple to a power tool, a tool system, and tool accessory storage system. The tool accessory holder can be removed from the tool accessory case and coupled to the power tool and removed from the power tool and coupled to the tool accessory case. The tool system includes an accessory holder and a power tool. The tool accessory holder is alternately couplable to the tool accessory storage case and to the power tool.

A stackable power supply device, container or unit is provided. The power supply device includes an energy conversion module, such as a solar panel. The power supply device includes several power outlets, such as an interface to recharge rechargeable batteries for power tools, an electrical outlet, and a battery to store energy generated by the solar panel.
