A connecting device for connecting two or more components to one another, includes an inlet section and an outlet section. The inlet section and the outlet section respectively include one or more connectors for each of the two or more components, with one or more passages extending between the inlet section and the outlet section, with the connecting device being of single piece design and being plastic

Disclosed is an adjustable and portable fire protection sprinkler system. The device consists of a sprinkler head mounted on an adjustable height center pole connected to adjustable legs, forming a foldable tripod-like configuration. The legs and center pole have inner and outer tubes arranged for telescopic movement relative to each other, for adjusting the height of the pole and the lengths of the legs. The sprinkler head is connected to a rubber hose which is threaded through the top of the center pole and connected to a water source at the bottom. The tube stretches and retracts inside the pole corresponding to the pole height. A collar around the pole connected to the legs, wherein the legs connected to the end of the pole by metal strips. This allows for sliding up and down; increasing or decreasing the triangular base parameter. The base is also defined by the length of the legs and is adjusted to maintain the tripod stability.

A hose connector has: a cap, a connecting pipe and an assembly pipe. The cap has an inner ring and an outer ring, and the inner ring is provided with an inner threaded hole. The cap further has a socket hole connected with the inner threaded hole, the outer ring is provided with an outer threaded section. The connecting pipe has an inserting portion at one end and a first threaded portion at another end. The inserting portion has a neck section and a stopping ring. The inserting portion is disposed in the socket hole of the cap. The stopping ring comprises at least one protrusion facing the groove. The assembly pipe has a through hole and a convex ring at one end and a second threaded portion at another end. The second threaded portion of the assembly pipe engages with the inner threaded hole of the cap.

A hose connector has a first connecting joint, a second connecting joint, and a connecting duct. The first connecting joint comprises an inner neck rim having an inner threaded aperture and a containment space connecting to the inner threaded aperture. The first connecting joint further comprises a threaded outer wall, and a bottom surface of the neck rim has a plurality of engaging grooves. The second connecting joint comprises a hollow base having a neck section connected to a lip, and the neck section is configured for insertion in the containment space of the first connecting joint. A top surface of the lip has a plurality of engaging protrusions pushing against the neck rim or engaging with the engaging groove. The connecting duct comprises an outer threaded section and an enlarged flange, and the connecting duct is mounted through the neck section and the lip.

A sprinkler riser extension kit elevates a pop-up sprinkler that has a riser and a head detachable from the riser. The kit includes a gripping head having a channel extending therethrough, and a riser extension configured to slide within the channel and having a length corresponding to the length of the channel. The lower end of the gripping head is configured for attachment to the sprinkler, e.g., by a plurality of flexible pawls spaced evenly about the lower end. The riser extension includes means for attachment between the sprinkler head and the sprinkler riser. To elevate the sprinkler, the head is detached, the riser passed through the gripping head, the riser extension attached to the riser, the head attached to the riser extension, and the gripping head attached to the top of the sprinkler.
