Description

Technical Field

[0001] The utility model relates to the technical field of sanitary wares, in particular to a washbasin faucet. Background Art

[0002] There is a existing washbasin faucet, which includes a shell, a mounting pipe, a valve core, a valve seat and a switch. An outlet is provided on the shell. The valve core and the valve seat are arranged in the mounting pipe. The valve core is rotatably arranged on the valve seat. The valve seat is provided with a cold water inlet and a hot water inlet. The switch is linked and cooperated with the valve core. The switch is arranged in a sleeve structure. The shell includes a water outlet pipe and a connecting pipe which are mutually communicated. The connecting pipe is connected with the mounting pipe. The upper end of the valve core extends into the connecting pipe. The outlet is arranged on the water outlet pipe. The switch is sleeved on the outer periphery of the connecting pipe and is rotatably arranged on the mounting pipe. The switch and the valve core are connected through a connecting component to realize the linked cooperation between the switch and the valve core.

[0003] For the above-mentioned washbasin faucet, the switch and the valve core are cooperated through teeth. When the switch is rotated, the valve core is driven to rotate. However, there is a gap between the teeth, and after long-term use, it is easy to produce shaking, resulting in poor stability and unable to drive the valve core to rotate well. At the same time, the valve core is arranged in the mounting pipe, resulting in a long distance between the valve core and the switch, which makes the installation inconvenient and the stability is also poor. Summary of the Invention

[0004] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a washbasin faucet. A fastener is arranged between the valve core and the rotating sleeve, so that the structure between the valve core and the rotating sleeve is more firm, and the valve core is arranged in the shell, shortening the distance between the valve core and the rotating sleeve, facilitating installation and improving stability.

[0005] The technical solution of the utility model: A washbasin faucet includes a shell, a valve core, a valve seat and a rotating sleeve. The shell includes a connecting pipe and a water outlet pipe which are mutually communicated. An outlet is provided on the water outlet pipe. The rotating sleeve is sleeved outside the connecting pipe. The valve core and the valve seat are arranged in the connecting pipe. A collar synchronously rotating with the valve core is sleeved outside the valve core. An extension part is provided on the collar. A threaded hole is provided on the extension part. A mounting hole is correspondingly opened on the rotating sleeve. The fastener passes through the mounting hole and is in threaded cooperation with the threaded hole.

[0006] By adopting the above technical solution, the valve core and the rotating sleeve are further connected through the fastener, making the structure between the two more firm. At the same time, the valve core and the valve seat are installed in the connecting pipe, shortening the distance between the valve core and the rotating sleeve, making the valve core more stable, facilitating installation and saving costs.

[0007] Further setting of the utility model: A first chamber, a second chamber and a third chamber are arranged in the connecting pipe, and the three chambers are communicated with each other. The valve seat and the valve core are arranged in the first chamber. A rotating shaft is integrally provided or fixedly connected to the valve core. The inside of the rotating shaft is hollowly arranged. The upper end of the rotating shaft passes through the second chamber and extends into the third chamber. The collar is located in the second chamber. An arc-shaped groove is formed on the side wall of the second chamber. Driven by the rotating sleeve, the extension part slides in the arc-shaped groove.

[0008] With the above further setting, it is convenient for the installation of the valve core. The setting of the arc-shaped groove can not only make the structure stable when the valve core rotates driven by the rotating sleeve, play a guiding role, but also play a limiting role to limit the rotation angle.

[0009] Another further setting of the utility model: A ring-shaped boss with a central opening is arranged at the connection between the first chamber and the second chamber. The upper end of the rotating shaft passes through the ring-shaped boss, and the lower end of the rotating shaft is located inside the valve core. A step surface is arranged at the upper end of the valve core, and the ring-shaped boss is in contact with the step surface.

[0010] With the above another further setting, the first chamber and the second chamber are communicated, which is convenient for the rotating shaft to extend into the third chamber. The contact between the ring-shaped boss and the step surface can position the valve core so that it can only rotate circumferentially and cannot move axially up and down.

[0011] Another further further setting of the utility model: A channel for communicating the second chamber and the third chamber is arranged at the bottom of the third chamber. The upper end of the rotating shaft is rotatably arranged in the channel, and a sealing member is arranged on the outer wall of the rotating shaft.

[0012] With the above another further further setting, the sealing performance is good, so that water can only flow out from the rotating shaft into the third chamber to avoid water leakage.

[0013] Another further further setting of the utility model: A barrier member is arranged between the upper end of the rotating sleeve and the connecting pipe, and the barrier member is arranged in a horn shape.

[0014] With the above another further further setting, it can play a role in anti-wear and avoid abrasion between the rotating sleeve and the connecting pipe when the rotating sleeve rotates. The barrier member is made of plastic and has elasticity, which is convenient for the installation of the rotating sleeve.

[0015] Another further further setting of the utility model: It further includes an installation pipe, and the installation pipe is located below the shell and is detachably connected to the shell.

[0016] With the above another further further setting, the lower end of the installation pipe is installed below the washbasin countertop. The cold and hot water inlet pipes extend into the installation pipe from below and extend into the shell to be connected to the valve seat, which can play a role in protecting the inlet pipes.
