Description

TECHNICAL FIELD

[0001] The utility model relates to a shower device, especially a curved foot. BACKGROUND

[0002] The prior art, Chinese patent 201810939219.6, discloses a curved foot connecting structure, which comprises a curved foot and a connecting pipe. The curved foot and the connecting pipe are connected through insertion and can rotate relative to each other. A sealing ring is arranged between the curved foot and the connecting pipe. A faucet comprises a body and the curved foot connecting structure described above. The connecting pipe is connected to the body. The curved foot connecting structure and the faucet using the structure can only adjust the angle relationship between the curved foot and the connecting pipe during installation. The two are sealed by the sealing ring and do not need to use raw rubber, thereby eliminating problems such as easy detachment and wear of the rubber tape. However, there are still problems such as water leakage due to temperature changes. SUMMARY

[0003] The utility model aims to provide a curved foot which has good sealing performance and is not affected by temperature changes.

[0004] The utility model is implemented in the following manner: a curved foot, which is characterized by comprising an external thread joint pipe portion, a seat plate portion, an insertion pipe portion, and a sealing sleeve,

[0005] The insertion pipe portion is provided with a sealing groove and an annular positioning groove at the overhanging end.

[0006] The outer circumferential surface of the sealing sleeve is in the shape of a truncated cone.

[0007] The external thread joint pipe portion and the insertion pipe portion are respectively located on the two sides of the seat plate portion and are connected, and the axes of the external thread joint pipe portion and the insertion pipe portion are spaced apart. The sealing sleeve is arranged in the sealing groove and has a top circular end facing the overhanging end of the insertion pipe portion.

[0008] The curved foot is characterized in that the seat plate portion has two flat surfaces for driving by a rotating tool.

[0009] The curved foot is characterized in that the seat plate portion comprises a rectangular portion and circular arc portions at both ends.

[0010] The curved foot is characterized in that the sealing sleeve is made of silica gel material.

[0011] The curved foot is characterized in that the bottom plate of the annular positioning groove is in the shape of a truncated cone and has a bottom circular end facing the overhanging end of the insertion pipe portion.

[0012] This utility model features a curved foot and a sealing sleeve with an outer circumferential surface shaped like a frustum cone, which improves sealing performance and maintains sealing performance even during temperature changes, thermal expansion or contraction of the sealing sleeve.

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] like Figure 1 , Figure 2 As shown, a curved joint includes an externally threaded connector tube portion 1, a seat plate portion 2, a insertion tube portion 3, and a sealing sleeve 4.

[0020] The insertion pipe 3 is provided with a sealing groove 31 and an annular positioning groove 32 starting from the suspended end;

[0021] The outer circumferential surface of the sealing sleeve 4 is shaped like a frustum conical.

[0022] The external threaded connector tube 1 and the insertion tube 3 are located on both sides of the seat plate 2 and are connected. There is a gap between the axes of the external threaded connector tube 1 and the insertion tube 3. The sealing sleeve 4 is provided with a sealing groove 31 and its top round end faces the suspended end of the insertion tube 3.

[0023] As a further improvement of this utility model: the seat plate 2 has two planes 21 for rotating tools to drive.

[0024] The seat plate 2 comprises a rectangular portion and circular arc portions at both ends.

[0025] The sealing sleeve 4 is made of silica gel material.
