Abstract: A single waterway shaft structure includes a valve housing, a valve cover, a temperature control rod assembly composed of a water stopper and a temperature adjustment rod, a spring, and a gasket. A lower portion of the temperature control rod assembly is formed with an eccentric water hole. The gasket and the spring are placed in an eccentric water inlet of the valve housing in order and confined in the valve housing. The temperature control rod assembly cooperates with a faucet handle. A one-way connecting structure is provided between the valve cover and the valve housing. An upper end of the valve cover is provided with a fan-shaped limit block for limiting the turning angle of the temperature control rod assembly. The shaft is designed to be one-piece.

Abstract: The invention provides a fluid delivery assembly for use with a water discharge fixture, such as a faucet. The fluid delivery assembly includes a tube assembly, a cartridge housing and a retaining assembly. The fluid delivery assembly provides for water flow from hot and cold water inlets to the faucet. The fluid delivery assembly may be assembled by hand without the need for tools, allowing for easy replacement of the fluid delivery assembly without the need to disassemble the faucet assembly or to replace the entire faucet assembly.

Abstract: A drain plug linkage device (100) comprises a pull rod assembly (10) including a pull rod (1) and a link rod (2) operatively connected with each other; a lever member (3); and an engagement mechanism (6). One of the link rod (2) and the lever member (3) comprises a plurality of through-holes (21) and has the engagement mechanism (6) slidably mounted thereon, and the other one of the link rod (2) and the lever member (3) is configured to be inserted through one of the through-holes (21) and includes a plurality of axially-spaced circumferential ridges (32) and recesses (33) defined between the circumferential ridges (32). The engagement mechanism (6) is configured, when sliding into a position of engaging with the recess (33), to prevent the other one of the link rod (2) and the lever member (3) from being axially displaced with respect to the through-hole (21).

Abstract: A quick assembly and disassembly mechanism includes a nut seat and a slide block which is movably coupled to the nut seat. The nut seat includes at least two cantilever lock blocks therein. The inner wall of each lock block has threads thereon. The inner diameter encircled by the lock blocks matches with a bolt of a faucet. In normal state, the nut seat can be moved freely on the bolt. When the nut seat is moved to a counter top to compress the slide block, the slide block will push the lock blocks to mesh with the bolt tightly, so that the faucet can be mounted and dismounted quickly.

Abstract: A quick assembly and disassembly mechanism for a faucet includes a main body, a movable lock block disposed in the main body, a press plate which is movably disposed on the main body, and push blocks which are movably disposed on the main body and driven by the press plate. When the main body is moved to the counter top to compress the press plate, the press plate will hold against the push blocks to push the lock block to mesh with the bolt tightly, so that the faucet can be mounted and dismounted quickly. The assembly and disassembly of the faucet and the related parts is more convenient and quick.
