Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment, and in particular to an all-plastic faucet pipe structure and faucet. Background Technology

[0002] There are generally two types of faucets. The first type is where the faucet itself acts as the water outlet pipe, directly draining water. The second type includes a protective and supportive pipe structure as well as an independent water supply pipe located within the pipe structure. The second type of faucet is mainly used in faucets with hot and cold water functions, as well as faucets for water purifiers.

[0003] Currently, the second type of faucet has a pipe structure 1, such as... Figure 1 As shown, it mainly includes a threaded base 11, a support tube 12, and a water outlet 13. The base 11 is usually located at the bottom of the sink. After the head of the base 11 is drilled out of the sink, it is screwed to the support tube 12. The base serves to limit and fix the support tube. The water outlet 13 is usually rotatably connected to the support tube 12. The water outlet 13 usually has a knob 14 for controlling the water flow.

[0004] Regarding the aforementioned faucet pipe structure, to save costs, manufacturers typically use plastic parts for the base 11 and the water outlet 13, while the support pipe 12 is made of metal. One problem caused by these different materials is inconsistent surface coloring; paints behave differently on different materials, resulting in color variations in the product. Electroplating would be too expensive. Another issue is that to ensure a smooth and tactile experience when the water outlet rotates, providing a sense of freedom of movement, two sealing rings are usually installed at the connection between the water outlet and the support pipe. Without these sealing rings, rotating the water outlet would feel... The surface feels very stiff and rough, with a strong sense of friction, even producing an unpleasant scraping sound, resulting in a very poor user experience. To make the rotation smoother, the sealing ring is usually coated with silicone oil. During the transportation of this product, the silicone oil may overflow from the connection between the water outlet and the support tube (the amount of silicone oil on the sealing ring is very small, but because the water outlet is laid flat during transportation, silicone oil overflows, which is a low-probability event). The silicone oil will seep into the surface of the tube material and cannot be removed, causing color spots when the tube is colored later. The connection between the water outlet and the support tube is a commonly seen area by users, and the appearance of color spots makes the product a defective product.

[0005] The aforementioned faucet pipe structure also suffers from problems such as high manufacturing costs, numerous parts, and complex structure. Summary of the Invention

[0006] In view of this, it is necessary to provide an all-plastic faucet pipe structure and faucet that is low in manufacturing cost, simple in structure, and does not leak silicone oil.

[0007] To solve the above-mentioned technical problems, one technical solution of this utility model is: an all-plastic faucet pipe structure:

[0008] Includes a support pipe, a reinforcing pipe, and a water outlet pipe, all made of plastic.

[0009] The bottom of the support tube has an externally threaded tube;

[0010] The reinforcing tube is rotatably connected to the inside of the supporting tube, and the top of the reinforcing tube protrudes beyond the top of the supporting tube;

[0011] The water outlet pipe head is fixedly connected to the top of the reinforcing pipe, and the outer diameter of the connection section between the water outlet pipe head and the reinforcing pipe is equal to the outer diameter of the supporting pipe.

[0012] Furthermore, the bottom of the outer wall of the reinforcing tube has a circumferential travel groove, within which a limiting block is slidably connected, and the bottom of the side wall of the supporting tube has a limiting hole for the limiting block to be embedded.

[0013] Furthermore, the outer wall of the limiting block is flush with the outer wall of the supporting tube.

[0014] Furthermore, the reinforcing tube is a tube with hollowed-out sidewalls.

[0015] Furthermore, the water outlet pipe head is snapped together with the reinforcing pipe.

[0016] Furthermore, the top of the side wall of the reinforcing pipe has a protrusion, and the bottom of the side wall of the water outlet pipe head has a groove that engages with the protrusion.

[0017] Furthermore, a first sealing ring is fitted onto both the upper and lower parts of the outer side wall of the reinforcing tube, and the outer periphery of the first sealing ring is slidably connected to the inner side wall of the supporting tube.

[0018] Furthermore, a leak-proof sealing ring is also fitted above the first sealing ring located on the upper part of the outer wall of the reinforcing tube.

[0019] Furthermore, the outer walls of the reinforcing tube where the first sealing ring and the leak-proof sealing ring are located are both complete annular outer walls.

[0020] To solve the above-mentioned technical problems, one technical solution of this utility model is: a faucet, wherein the all-plastic faucet has the all-plastic faucet tube structure as described above.

[0021] Compared with the prior art, the present invention has the following advantages: The device has an annular groove above the first sealing ring on the upper part of the outer wall of the reinforcing tube, and a leak-proof sealing ring is fitted inside the annular groove. When the device is laid flat, when the silicone oil of the first sealing ring on the upper part of the outer wall of the reinforcing tube overflows, it will be blocked by the leak-proof sealing ring from flowing towards the outlet pipe head; the manufacturing cost is low, the structure is simple, and the silicone oil does not leak out.

[0022] To make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0028] To further illustrate the technical means and effects of this utility model in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below. Example 1

[0029] like Figure 2-4 As shown, a fully plastic faucet pipe structure includes a support pipe 2, a reinforcing pipe 4, and a water outlet pipe 3, all made of plastic, and all three are manufactured by integral injection molding.

[0030] The support tube 2 has an external threaded tube 21 at its bottom. Taking the installation of this device in a sink as an example, there is a through hole on the top of both the left and right sides of the sink. The outer diameter of the external threaded tube 21 is smaller than the inner diameter of the through hole, so it can pass freely through the through hole. The outer diameter of the support tube 2 is larger than the inner diameter of the through hole. The external threaded tube 21 is inserted into the through hole from the top of the sink, and a suitable nut is screwed onto the external threaded tube 21 at the bottom of the sink, thereby fixing the support tube 2 to the sink.

[0031] The reinforcing tube 4 is rotatably connected to the inside of the supporting tube 2. The top of the reinforcing tube 4 protrudes from the top of the supporting tube 2. In order to save materials, the reinforcing tube 4 is a tube with hollowed-out side walls.

[0032] The water outlet head 3 is fixedly connected to the top of the reinforcing pipe 4, and the outer diameter of the connection section between the water outlet head 3 and the reinforcing pipe 4 is equal to the outer diameter of the support pipe 2.

[0033] To prevent the reinforcing pipe 4 from detaching from the supporting pipe and to limit the rotation angle of the outlet pipe head 3, the bottom of the outer wall of the reinforcing pipe 4 has a circumferential travel groove 41 (in this embodiment, the travel groove occupies an angle range of 120° in the circumferential direction of the reinforcing pipe), and a limiting block 42 is slidably connected in the travel groove 41. The bottom of the side wall of the supporting pipe 2 has a limiting hole for the limiting block 42 to be embedded.

[0034] In this embodiment, the water outlet head 3 is snapped together with the reinforcing pipe 4. The top of the side wall of the reinforcing pipe 4 has a protruding buckle 43, and the bottom of the side wall of the water outlet head 3 has a groove that engages with the protruding buckle. The outer side wall of the protruding buckle is flush with the outer side wall of the water outlet head.

[0035] To make the rotation of the water outlet head 3 more smooth and responsive, an annular groove 46 is provided on the upper and lower parts of the outer side wall of the reinforcing pipe 4. A first sealing ring 44 is fitted inside the annular groove 46, and the outer periphery of the first sealing ring 44 is slidably connected to the inner side wall of the support pipe 2.

[0036] To ensure smoother rotation of the reinforcing tube 4 within the supporting tube 2 and reduce frictional resistance, the first sealing ring 44 is coated with silicone oil. To prevent silicone oil from overflowing from the connection between the outlet pipe and the supporting tube when the device is laid flat, an annular groove 46 is provided above the first sealing ring 44 on the upper part of the outer wall of the reinforcing tube. A leak-proof sealing ring 45 is fitted inside this annular groove. That is, when the device is laid flat, if silicone oil overflows from the first sealing ring on the upper part of the outer wall of the reinforcing tube 4, it will be blocked by the leak-proof sealing ring from flowing towards the outlet pipe. Because the amount of silicone oil is very small, the flow trajectory of the silicone oil is linear, so the silicone oil cannot cross the reinforcing tube and then flow to the connection between the outlet pipe and the supporting tube.

[0037] In this embodiment, in order to better install the first sealing ring and the leak-proof sealing ring, the outer side wall of the reinforcing tube of the first sealing ring and the leak-proof sealing ring is a complete annular outer side wall. Of course, the annular groove is also provided on the annular outer side wall. Example 2

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
