Description

Pull-out faucet and magnet bushing structure for a pull-out faucet

Technical Field

The utility model relates to a pull-out faucet and a magnet bushing structure for the pull-out faucet.

Background

Conventional removable faucets currently on the market include faucet bodies, faucet elbows, and pull-out faucets. The tail end of the tap bent pipe is provided with a magnetic suction bushing, and the pull-out water head is arranged at the tail end of the tap bent pipe in a pull-out way, so that the magnetic suction bushing can realize magnetic suction positioning of the pull-out water head. The connection mode of the magnetic attraction bushing and the tap elbow is generally as follows:

In the first connecting mode, the magnetic attraction bushing is provided with a claw, and the magnetic attraction bushing is directly clamped on a machining groove on the inner wall of the faucet elbow through the claw. Disassembly is indeed possible in the first connection, but the tap elbow requires a very thick wall thickness for the placement of the machined groove, and the entire tap elbow is very heavy and costly. The claw is clamped on the machining groove of the inner wall of the water nozzle pipe through the magnet bushing. The elastic force of the plastic is used, so that the clamping jaw recovers a certain deformation amount after passing through the interference section. The claw can not fall down after being opened. And can bear the downward pulling force meeting the requirements. The magnet bushing can be disassembled. However, the clamping groove is placed on the water nozzle, so that the wall thickness of the water nozzle pipe is too thick and the grooving machine of the water nozzle is high in cost.

In the second connection mode, the magnet bush is clamped on the machining groove in the groove of the water nozzle pipe. But need to be fixed by glue. This structure cannot be disassembled. However, the water nozzle tube does not need to have thick wall thickness, and the cost is low because the clamping groove is arranged. The structure is clamped on a machining groove in a groove of the faucet elbow through a magnet bushing. But need to be fixed by glue. Can bear the downward pulling force meeting the requirement. The structure cannot be disassembled. However, the water nozzle tube does not need a great wall thickness, and the clamping groove is arranged. The cost is low.
