Quick connector of pull-out faucet and quick-connection pull-out faucet structure

Abstract

The invention discloses a quick connector of a pull-out faucet and a quick-connection pull-out faucet structure. The quick connector of the pull-out faucet comprises a male connector and a female connector used for sealing the plug-in water inlet pipe, and further comprises a check valve located in the female connector and communicated with the male connector water channel, an elastic positioningclip is arranged on the outer wall of the male connector, a clamping protrusion is arranged on the elastic positioning clip in a protruding mode, the female connector is provided with a positioning clamping hole matched with the clamping protrusion, the check valve is of a cylindrical structure, the outer wall of the check valve is in sealed contact with the inner wall of the female connector, thetwo ends of the check valve are correspondingly provided with a water inlet hole and a water outlet hole, a plugging core used for blocking the water inlet hole and can be elastically reset is arranged in the check valve. The novel quick connector of the pull-out faucet has an innovative clamp spring design, the insertion connection is easy to clamp, the positioning is not backward, the connection can be removed by pressing the clamping protrusion, quick connector of the pull-out faucet is small in size, capable of passing through fine space such as a faucet nut and the like, and is very convenient to operate, and water can be prevented from flowing back, dropping water and leakage water.

Description

technical field [0001] The invention relates to a pull-out faucet structure, in particular to a pull-out faucet quick joint and a quick-connect pull-out faucet structure. Background technique [0002] The pull-out pipe or hose of the existing kitchen faucet is connected to the water inlet or the hot and cold mixed water through the joint of the threaded connection structure or the old-style quick connection structure. Because the threaded connection structure hinders the space under the basin , it is inconvenient to operate and difficult to tighten, and the old-style quick-connect structure joint structure is large, and it is not convenient to pass through the installation nut of the faucet and the installation hole of the countertop and the sink. Moreover, these joint structures do not have a check valve mechanism. Turning off the water flow will easily cause dripping and water leakage in the joint. [0003] At the same time, the pulling of the traditional pull-out faucet ...

[0002] The pull-out pipe or hose of the existing kitchen faucet is connected to the water inlet or the hot and cold mixed water through the joint of the threaded connection structure or the old-style quick connection structure. Because the threaded connection structure hinders the space under the basin , it is inconvenient to operate and difficult to tighten, and the old-style quick-connect structure joint structure is large, and it is not convenient to pass through the installation nut of the faucet and the installation hole of the countertop and the sink. Moreover, these joint structures do not have a check valve mechanism. Turning off the water flow will easily cause dripping and water leakage in the joint

[0003] At the same time, the pull of the traditional pull-out faucet is not smooth, the reset is not good, and the position is easy to be wrong, so the installation and use of the pull-out faucet as a whole are not good enough.
