The present invention provides a box latch. The box latch is provided with two wedge-shaped pins symmetrically arranged around its center, and the two wedge-shaped pins are movable into a wedge-shaped notch formed by mating parts of two spliced adjacent boxes and mating with the wedge-shaped pin to lock the two adjacent boxes. The two wedge-shaped pins are symmetrically arranged around its center such that only one box latch is required to lock two adjacent boxes together, reducing the number of splicing steps and box latches, further saving manpower and material resources. In addition, the wedge-shaped pin and the wedge-shaped notch are shaped and configured to mate with each other such that self-locking occurs when they are locked, thus providing a stable connection of the boxes.

A fastener unit and related method for securing a board to a support is provided. The fastener unit includes a spacer block, a grip element extending from the spacer block and configured to fit in and engage a groove of the board, and one or more board engagement elements extending from a portion of the spacer block. The board engagement elements can clamp the board, between an upper and/or lower surface of the board and a groove of the board, thereby securing the spacer block in a position adjacent the groove to establish a gap between the board and another board. Related methods of use also are provided.

In order to provide a connecting device for connecting two components, which is simple to manufacture and enables a stable and reliable connection of the two components, it is proposed that the connecting device comprises a main body which comprises a receiving channel extending through the main body for accommodating a fixing element, wherein the receiving channel is preferably accessible at one end by way of an insertion opening of the main body and/or preferably at a (further) end by way of a fixing opening of the main body, wherein the main body preferably further comprises an actuating opening that is different from the insertion opening and/or the fixing opening, by way of which in particular the fixing element arranged in the receiving channel is preferably accessible for the actuation thereof.

A camera device comprises an assembly having a first component and a second component which are connected to each other with a hollow holding member and a threaded fastener. The first component has a first socket with a first socket opening and a threaded bore extending from a bottom surface of the first socket. The second component has a second socket with a second socket opening, wherein the first socket opening and the second socket opening are configured to face each other when the first and second component are connected to each other. The first and second sockets each have threaded bores. A threaded fastener is configured to extend from the second component to the threaded bore of the first socket of the first component for engagement with the threaded bore such that the connection between the first and second components is secured.

In various embodiments, a mounting system may comprise a downslope rail, an upslope rail, a first clamp and a second clamp. The downslope rail may have a first profile and comprising a downslope face and an upslope shelf. The upslope rail may have a second profile and comprising a downslope shelf and an upslope face. The first clamp may be configured to engage the downslope face and accept the installation of a first end of a solar panel. The second clamp may be configured to engage the upslope face and retain a second end of the solar panel against a downslope shelf

A fastener unit and related method for securing a board to a support is provided. The fastener unit includes a spacer block, a grip element extending from the spacer block and configured to fit in and engage a groove of the board, and one or more board engagement elements extending from a portion of the spacer block. The board engagement elements can clamp the board, between an upper and/or lower surface of the board and a groove of the board, thereby securing the spacer block in a position adjacent the groove to establish a gap between the board and another board. Related methods of use also are provided.

A connecting structure connecting a first device and a second device rigidly but readily demountably comprises a housing having a top cover and a bottom cover to form an internal space. A connector which has an engagement block, a sliding block, and an insert block engages with the second device. A push button having a knob movably mounted on the housing, a sprung hooking structure having a guiding slot engaging with the sliding block, and a hook engaging with the second device provide demountable. The push button resists the engagement block via a through hole of the top cover, the connecting structure being combined with the connector to link with the hooking structure.

Floor panels are shown, which are provided with a mechanical locking system including a flexible tongue in a displacement groove. The flexible tongue may be formed from the core material of the floor panels and inserted during production into the displacement groove. The locking system may be locked with vertical folding.

A fastener for a grooved joint between furniture panels is disclosed, including a connecting rod having an outer periphery which includes a first peripheral section and a second peripheral section, where the first peripheral section is a geometric cross section and the second peripheral section is of an arc shape; the first peripheral section and the second peripheral section are connected end to end; and a face of one end of the connecting rod is provided with an installation recess for turning the fastener for a grooved joint between furniture panels; an outer surface of the connecting rod is provided with a thread and a stop perpendicular to a direction of the thread; and the other end of the connecting rod is provided with a ratchet. The fastener is convenient to install and uninstall and does not damage back panels or installation panels.

The present invention relates to a construction kit and, in particular, modular flooring elements for the assembly of a modular raised floor base with detachable and interchangeable cover plates. More specifically, the stackable floor elements with associated presentation pedestal that may be assembled horizontally or vertically in order to assemble a presentation floor or stage to showcase products. The main objective of the present invention is to provide improved coupling means for a composition between floor elements, blocks, and cover plates which further allows to make a wide variety of floors with different heights and shapes.
