Disclosed is an arc-shaped adjustment lock, including: a base, an adjustment component, and a pressing lock assembly. The base is connected to a first LED cabinet. The base has a first arc-shaped portion. The adjustment component is connected to a second LED cabinet. The adjustment component has a second arc-shaped portion fitted with the first arc-shaped portion. The first arc-shaped portion and the second arc-shaped portion are slidingly matching with two elastic beads along an arc through a staggered double V-shaped groove group. The first arc-shaped portion and the second arc-shaped portion are locked through the pressing lock assembly after sliding along the arc.

A panel fasteners (20) is disclosed in the form of a hook and cam assembly (21) having two side walls (24) with a boss (27) through which a cam shaft (28) is journalled. The cam shaft has a socket (29) and a round cam (30). A hook (32) is frictionally mounted in camming engagement with the cam. A leaf clutch spring (33) is mounted within a spring mounting notch (36) and in frictional engagement with a substantially round cam engagement hole (34) of the hook. To position the spring into the spring mounting notch and cam engagement hole the spring is pre-compressed prior to mounting it within the spring mounting notch by forcing it through a narrowing channel positioned adjacent the cam.

The present invention includes a multiuse clip assembly which can be employed to secure objects or panels to one another. It incorporates both the male and female features into each clip for greater versatility and durability over conventional clip systems. The unique universal and expandable mating system does not limit the orientation, position, or number of objects or panels that may be secured to one another.

A modular multi-container housing structure connector for containers, which each have sides including a roof, a floor, and four lateral sides, includes a connector frame comprising vertical and horizontal struts shaped to connect to at least one of the sides of two adjacent containers and at least one interlock configured to secure the connector frame to the side of one container. The at least one interlock may be a plurality of interlocks. The connector frame may comprise two vertical struts and two horizontal struts each shaped and configured to connect to a respective edge of an adjacent side of two adjacent containers and, responsive to the connector frame being connected to two adjacent sides of two adjacent containers by the plurality of interlocks, the connector frame and interlocks form a container-to-connector frame-to-container connection to establish a weather-tight housing structure with the two or multiple connected containers.

A connection device for mobile frame structures includes a bracket on a surface having a cam shaft and a cam lock has a spiral axial slot having a locking groove and a central cam groove. A cam follower, a spring and a force stop are positioned in the central cam groove. A retention device holds the components in the cam groove. A structural support is engaged to the cam lock. An intersection between the spiral axial slot and the central cam groove has one or more detents which engage the cam follower prior to engagement of the cam lock to the bracket. The cam shaft is positioned in the spiral axial slot and the cam lock is rotated moving the cam shaft into the locking groove and depressing the cam follower relative to the spring to lock the cam shaft into the locking groove.

An adjusting mechanism of a box and a light emitting diode (LED) box assembly are provided.
