[0001] The utility model provides a single-hole faucet for washbasin, belonging to the technical field of faucets. Background Art

[0002] A faucet is a common name for a water valve, used to control the size of the water flow switch, with the effect of saving water. The replacement speed of faucets is very fast, developing from the old cast iron process to the electroplated knob type, and then to the stainless steel single-temperature single-control faucet, stainless steel double-temperature double-control faucet, and semi-automatic kitchen faucet. Now, more and more consumers will comprehensively consider various aspects such as material, function, and shape when purchasing a faucet.

[0003] Based on the above, the inventor found that:

[0004] The traditional faucet has a complex structure, involving many components. The more components there are, the more troublesome the installation is, which is not conducive to the operation of workers.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure, and a single-hole faucet for washbasin is proposed to solve the above problems. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is that the traditional faucet has a complex structure, is not easy to install, and is not conducive to the operation of workers.

[0007] To solve the above problems, the technical solution proposed by the utility model is: a single-hole faucet for washbasin, including a handle and a water outlet cavity. The handle is located above the water outlet cavity. There are faucet accessories inside the water outlet cavity, and the faucet accessories include a valve cap, a first fixing ring, a valve core, a positioning ring, and a second fixing ring. The valve cap, the first fixing ring, the valve core, the positioning ring, and the second fixing ring are arranged in the water outlet cavity from top to bottom in sequence.

[0008] Further, a limiting protrusion is arranged inside the lower end of the water outlet cavity. The positioning ring is placed in the water outlet cavity, and the limiting protrusion contacts the upper end of the positioning ring. The second fixing ring is threadedly connected to the inner lower end of the water outlet cavity.

[0009] Further, the positioning ring is provided with a groove and a through hole adapted to the lower end of the valve core, and the bottom of the triangular cylinder at the lower end of the valve core is placed in the groove, and the cylinder corresponds to the through hole.

[0010] Further, the first fixing ring is sleeved outside the upper end of the valve core and is partially threadedly connected to the inner wall of the upper end of the water outlet cavity. The valve cap is threadedly connected to the first fixing ring and is close to the upper end of the water outlet cavity at the lower end.

[0011] Further, a limiting groove adapted to the upper end of the valve core is arranged inside the handle, and the upper end of the valve core is placed in the limiting groove.

[0012] Due to the adoption of the above technical solution, the beneficial effects of a single-hole basin faucet of the present utility model are as follows: Through the design of the limiting protrusion, positioning ring and fixing ring, each component of the faucet can be stably fixed in the water outlet cavity. Through threaded connection and component adaptation, the structure of the faucet is ensured to be simple, the installation is more convenient, and it is more conducive to the operation of workers.

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] The problems of the prior art are fully interpreted in the technical background of this application, and there are no upper-level or general problems. The problems to be solved by this application are specifically described in the following utility model content and detailed implementation manners, clarifying the technical problems to be solved by the technical solutions, and determining that the technical solutions of this application have beneficial effects relative to the objective prior art.

[0021] Please refer to Figures 1 - 3As shown in the figure: The utility model provides a single-hole faucet for a washbasin, which includes a handle 1 and a water outlet cavity 2. The handle 1 is located above the water outlet cavity 2. There are faucet fittings inside the water outlet cavity 2, and the faucet fittings include a valve cap 3, a first fixing ring 4, a valve core 5, a positioning ring 6, and a second fixing ring 7. The valve cap 3, the first fixing ring 4, the valve core 5, the positioning ring 6, and the second fixing ring 7 are arranged in the water outlet cavity 2 from top to bottom in sequence.

[0022] A limiting protrusion 8 is arranged inside the lower end of the water outlet cavity 2. The positioning ring 6 is placed in the water outlet cavity 2, and the limiting protrusion 8 contacts the upper end of the positioning ring 6. The second fixing ring 7 is threadedly connected to the inner lower end of the water outlet cavity 2.

[0023] As Figures 2 - 3 shown, a groove 10 and a through hole 11 adapted to the lower end of the valve core 5 are arranged on the positioning ring 6, and the bottom of the triangular cylinder 12 at the lower end of the valve core 5 is placed in the groove 10, and the cylinder 13 corresponds to the through hole 11.

[0024] The first fixing ring 4 is sleeved on the outer side of the upper end of the valve core 5 and is partially threadedly connected to the inner wall of the upper end of the water outlet cavity 2. The valve cap 3 is threadedly connected to the first fixing ring 4 and the lower end is close to the upper end of the water outlet cavity 2.
