In order to facilitate an understanding of the embodiments of the present invention, the embodiments of the present invention will be described more fully hereinafter with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the examples of the present invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1 and 2, an embodiment of the present invention provides a curved pin assembly 1, including an adapter 10, a movable joint 20, and a resilient latch 30; the adapter 10 comprises a first mounting end 11, wherein the first mounting end 11 is provided with a mounting through hole 112 and a bayonet through hole 118 communicated with the mounting through hole 112; the movable joint 20 comprises a second mounting end 22, and the second mounting end 22 is detachably mounted in the mounting through hole 112; the resilient latch 30 passes through the latch aperture 118 and is at least partially captured between the first mounting end 11 and the second mounting end 22 to fixedly mount the second mounting end 22 of the movable connector 20 to the first mounting end 11 of the adapter 10.

Referring to fig. 1, in particular, the adapter 10 can be fixed on a wall surface to communicate with a tap water outlet pipe in the wall, so that water in the tap water pipe can flow into the curved foot assembly 1 from the adapter 10 and finally flow out from the faucet. Because the condition of the junction of the adapter 10 and the tap water pipe on the installation site is complex, the installation accuracy of the adapter 10 of some families is poor, that is, the verticality of the adapter 10 and the wall surface is low, if the whole curved foot component 1 is fixed, the verticality of the movable joint 20 and the wall surface is also low, the faucet is installed on the movable joint 20, and finally the installation accuracy of the faucet is low, and the situations of large gap between the faucet and the wall surface, deflection and the like can occur. Because the movable joint 20 is detachably arranged on the adapter 10, the movable joint 20 can be adjusted to rotate a certain angle relative to the adapter 10, and on the basis that the perpendicularity between the adapter 10 and the wall surface is low, the perpendicularity between the movable joint 20 and the wall surface can be improved by rotating the movable joint 20, so that the installation accuracy of the water faucet can be ensured. In this embodiment, the adapter 10 is a metal material, such as copper. In other embodiments, the adapter 10 may also be plastic or other rigid material.

Specifically, the first mounting end 11 is matched with the second mounting end 22, that is, the first mounting end 11 extends into the mounting through hole 112 of the second mounting end 22, and the first mounting end 11 and the second mounting end 22 are fixed by the elastic clamp pin 30, so that the movable joint 20 is fixedly mounted on the adapter 10.

Referring to fig. 3, 4 and 5, in the present embodiment, the first mounting end 11 includes a first abutting surface 114 and an inner surface 116, wherein the first abutting surface 114 is a circular ring surface, and the first abutting surface 114 can be used for abutting against the second mounting end 22. The inner surface 116 is a cylindrical surface and surrounds the mounting through hole 112, and the inner surface 116 is connected with the first abutting surface 114.

With reference to fig. 2, in the present embodiment, the latch through hole 118 includes two sets of latch arm through holes 118a, each set of latch arm through holes 118a includes an upper hole 1181 and a lower hole 1183, wherein the two upper holes 1181 are adjacent to each other and are located at the upper portion of the first mounting end 11, and the upper hole 1181 and the lower hole 1183 are correspondingly communicated; two lower apertures 1183 are adjacent and both located below the first mounting end 11, the spacing of the two lower apertures 1183 being greater than the spacing of the two upper apertures 1181 to mate with the resilient latch 30. In other embodiments, the latch through hole 118 may also include a set of latch arm through holes 118a, that is, the resilient latch 30 is inserted into the first mounting end 11 and not inserted out of the first mounting end 11, i.e., the portion of the resilient latch 30 inserted through the latch through hole 118 is entirely captured between the first mounting end 11 and the second mounting end 22.

Referring to fig. 2 and 4, the adapter 10 further includes a water inlet end 13 opposite to the first mounting end 11, the water inlet end 13 has a water inlet channel 132, the water inlet channel 132 is communicated with the mounting through hole 112, and an axis of the water inlet channel 132 is not aligned with and parallel to an axis of the mounting through hole 112. The outer peripheral surface of the water inlet end 13 is further provided with an external thread to facilitate the installation of the adapter 10, and specifically, the adapter 10 can be installed on a water outlet pipe in a wall through threaded connection.

In this embodiment, the movable joint 20 can move along the radial direction and the vertical direction relative to the adapter 10, so as to ensure that the movable joint 20 can be perpendicular to the wall surface, thereby improving the installation accuracy of the faucet and reducing the installation difficulty. The material of the movable joint 20 may also be copper. In other embodiments, the material of the movable joint 20 may also be stainless steel or other metallic materials.

Referring to fig. 2, 4 and 5, the second mounting end 22 includes a second abutting surface 221 and an outer surface 223, wherein the second abutting surface 221 is opposite to the first abutting surface 114, and the second abutting surface 221 can abut against the first mounting end 11. The outer surface 223 is opposite the inner surface 116, and the outer surface 223 may be used to mount a sealing gasket.

In the present embodiment, the outer diameter D2 of the second mounting end 22 is smaller than the inner diameter D1 of the first mounting end 11, so that the movable joint 20 can move in the radial direction relative to the adapter 10, and the amplitude of the radial movement can be 1 mm, that is, the movable joint 20 can move 0.5mm in one of the radial directions of the mounting through holes 112, for example, the movable joint 20 can move 0.5mm upward in the radial direction of the mounting through hole 112, and can also move 0.5mm downward in the radial direction of the mounting through hole 112, as shown in fig. 6. The difference between the inner diameter D1 of the first mounting end 11 and the outer diameter D2 of the second mounting end 22 is less than or equal to 1 mm, so as to ensure the stability of the connection between the second mounting end 22 and the first mounting end 11 and the sealing performance between the second mounting end 22 and the first mounting end 11. That is, when the difference between the inner diameter D1 of the first mounting end 11 and the outer diameter D2 of the second mounting end 22 is greater than 1 mm, the second mounting end 22 may be separated from the first mounting end 11 when the movable joint 20 moves relative to the adapter 10 in multiple directions, or the sealing property between the second mounting end 22 and the first mounting end 11 is deteriorated, and water may overflow between the first mounting end 11 and the second mounting end 22.

In this embodiment, the second mounting end 22 is provided with two spaced flanges 225, the flanges 225 projecting from the outer surface 223 in a direction toward the inner surface 116. In this embodiment, the flange 225 is spaced from the inner surface 116 of the first mounting end 11 to allow the movable joint 20 to move relative to the adapter 10 in multiple directions, i.e., the distance between the movable joint 20 and the adapter 10 can be adjusted to allow the movable joint 20 to be perpendicular to the wall surface to facilitate mounting of the faucet. The flange 225 may be used to capture the resilient latch 30 to increase the strength of the connection between the moveable joint 20 and the crossover joint 10.

Referring to fig. 2 and 4, the movable joint 20 further includes a water outlet end 24 and a water outlet channel 25, wherein the water outlet end 24 is opposite to the second mounting end 22, and the outer diameter of the water outlet end 24 is larger than the outer diameter of the second mounting end 22, so that the movable joint 20 is substantially in the shape of a hollow concentric cylinder, and in this embodiment, the water outlet end 24 can be abutted to the first mounting end 11. In other embodiments, the water outlet end 24 may also have a gap with the first mounting end 11.

The water outlet channel 25 connects the second mounting end 22 and the water outlet end 24, and water can flow out of the water outlet channel 25 and enter the faucet. In the present embodiment, the axis of the water outlet passage 25 coincides with the axis of the mounting through-hole 112. The outlet end 24 is provided with at least one external groove 243, and the external groove 243 can be used for embedding the external sealing ring 50 to realize the installation and sealing of the movable joint 20. In the present embodiment, the number of the outer insertion grooves 243 is two, and the two outer insertion grooves 243 are spaced apart from each other.

Referring to fig. 2, in the present embodiment, the elastic latch 30 includes two sets of opposing latch arms 31, one end of each set of latch arms is a connection end 311, and the two connection ends 311 are connected to each other, the other end of each set of latch arms 31 is a free end 312, and there is a gap between the two free ends 312, so that the elastic latch 30 is substantially n-shaped; the distance between the two free ends 312 gradually increases from the connecting end 311 to the free end 312, so that when the free end 312 is pressed, the free end 312 generates a restoring force and tends to expand outward. The free ends 312 of the two sets of snap arms 31 of the resilient latch 30 respectively pass through the two sets of snap arm through holes 118a and are at least partially snapped between the two flanges 225, and the distance between the two free ends 312 is larger than the distance between the two lower holes 1183, so that the two free ends 312 can pass through the two upper holes 1181 and be snapped in the two lower holes 1183 in sequence by pressing, and the resilient latch 30 is always in an expansion trend when being inserted into the snap arm through holes 118a, thereby increasing the connection stability of the movable joint 20 and the conversion joint 10. In the present embodiment, the width of the free end 312 is smaller than the width of the latch arm through hole 118a, so that the movable joint 20 can move in the vertical direction relative to the adapter 10, i.e. the movable joint 20 can move axially relative to the adapter 10, and the amplitude of the axial movement can be 0.2 mm, i.e. the movable joint 20 can move 0.1 mm in one of the axial directions of the mounting through hole 112, for example, the movable joint 20 can move 0.1 mm in the axial direction of the mounting through hole 112 toward the adapter 10, and can also move in the axial direction of the mounting through hole 112 away from the adapter 10, as shown in fig. 7. Specifically, the difference between the width of the latch arm through hole 118a and the width of the free end 312 is less than 0.2 mm, so as to ensure the stability of the connection between the second mounting end 22 and the first mounting end 11 and the sealing property between the second mounting end 22 and the first mounting end 11. In other embodiments, resilient latch 30 may further comprise a set of latch arms 31, i.e. resilient latch 30 may also be a rod-like structure. In this embodiment, the resilient latch 30 may be a stainless steel material. In other embodiments, the resilient latch 30 can be other materials.

In summary, the movable joint 20 can move in the radial direction relative to the adapter 10 and can also move in the vertical direction relative to the adapter 10. Therefore, even if the perpendicularity of the adapter 10 to the wall surface is low, the perpendicularity between the movable joint 20 and the wall surface can be improved by rotating the movable joint 20, so that the installation accuracy of the faucet can be ensured.

Referring to fig. 4 and 5, the curved leg assembly 1 further includes a sealing gasket 40, the sealing gasket 40 is disposed around the second mounting end 22 and between the second mounting end 22 and the first mounting end 11, and specifically, the sealing gasket 40 is disposed around the outer surface 223 and between the inner surface 116 and the outer surface 223. The sealing washer 40 is also in close contact with the first abutting surface 114, the inner surface 116 and the flange 225 far away from the water outlet end 24, and more specifically, the sealing washer can be clamped between the flange 225 and the first abutting surface 114 to improve the sealing performance between the first mounting end 11 and the second mounting end 22, so as to prevent water from overflowing from the first mounting end 11 and the second mounting end 22. In this embodiment, the sealing washer 40 may be made of rubber or silicone, so that the sealing washer 40 may be in interference fit with the flange 225 and the first abutting surface 114, and in this embodiment, when the movable joint 20 moves along the axial direction of the installation through hole 112, the compression amount of the sealing washer 40 may be 0.5 mm. The sealing gasket 40 also ensures that the movable joint 20 slides on the first abutment surface 114.

With continued reference to fig. 1 and fig. 2, the curved foot assembly 1 further includes at least one outer sealing ring 50, and the at least one outer sealing ring 50 is embedded in the at least one outer embedding groove 243. The outer sealing ring 50 may be used for connecting the movable joint 20 with the faucet, for example, the outer sealing ring 50 may be used for interference fit of the movable joint 20 with the faucet, so as to improve the sealing performance between the movable joint 20 and the faucet and prevent water from flowing out from between the movable joint 20 and the faucet. In this embodiment, the number of the outer sealing rings 50 is two, and the two outer sealing rings 50 are respectively embedded in the two embedding grooves. In other embodiments, the number of outer sealing rings 50 may also be one, three, four or more.

The installation steps of the curved foot component 1 of the invention are as follows:
