The stopping sleeve includes a first hole, a second hole, a first close washer with a first aperture, a second close washer with a second aperture, a first face, and a second face. Between the switch valve and the body is defined a limiting structure to limit a rotation of the switch valve, the switch valve includes a channel, a coupling stem, a first vent, and a second vent. The first close washer has a first seal ring, and the second close washer has a second seal ring. The rotatable control knob is joined with the coupling stem of the switch valve.
Abstract: A fixing structure for a vertical tap includes a vertical tap, a mounting member, a fitting member, a fixing ring, and a decorative loop. The mounting member secured in the ground includes a receiving chamber arranged on the top thereof and has two retaining tabs aft ached on the upper end thereof. The upper end of the fitting member screws with the lower end of the vertical tap. The fitting member includes two opposite fastening projections disposed on the outer periphery at the lower end thereof and extending outwardly therefrom. The fixing ring is fitted onto the external rim of the vertical tap, is then secured in a wooden floor by using a number of wood screws, and is further engaged with the internal rim of the vertical tap by way of a bolt. The decorative loop covers the fixing ring, thereby supporting and securing the vertical tap easily.
Abstract: A towel rack has a front section, multiple transversal rods and two positioning elements. The front section is U-shaped with two side tubes and is formed by a soldered metal tube. Multiple engaging holes are defined on inner sides of the side tubes of the front section in pairs so that each transversal rod is inserted into a pair of the engaging holes for assembly. Each positioning element is a rod with a semicircular cross-section and is inserted into the side tube to abut the ends of the transversal rods for compressing and positioning the transversal rods. Thereby, the towel rack is easy in processing and assembly to improve utility.
