Detailed Implementation Methods

[0032] To better understand the technical solution of this utility model, the technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Appendix Figure 1-10 As shown, this utility model provides a multi-angle adjustable water outlet support arm for a shower valve body 300, including an adapter 100 and a support arm assembly 200; one end of the support arm assembly 200 is connected to the adapter 100, and the other end is connected to the overhead shower head (not shown). The shower valve body 300 is connected to the water outlet interface of the wall.

[0034] Reference Appendix Figure 2-8As shown, the adapter 100 includes a water outlet component 1, a sleeve 2 fitted onto the outside of the water outlet component 1, and a first adjusting component 3 threadedly connected to one end of the water outlet component 1 and capable of pressing the sleeve 2 against the shower valve body 300; the outer wall of the sleeve 2 extends to provide a water outlet pipe section 21, which communicates with the inside of the sleeve 2; the water outlet pipe section 21 is used to connect the support arm assembly 200. The water outlet component 1 includes a first end 11 and a second end 12 arranged opposite to each other. The first end 11 is integrally connected to the shower valve body 300 (such as by welding or other fixed connection), and the second end 12 extends to provide a first external thread section 13; the first adjusting component 3 is threadedly connected to the first external thread section 13 and capable of pressing the sleeve 2 against the shower valve body 300. When the outrigger assembly 200 needs to be tilted (the outrigger assembly 200 rotates in the vertical direction, such as "head up" or "head down"), the first adjusting component 3 rotates outward to loosen the sleeve 2. The sleeve 2 can rotate around the water outlet component 1 as needed. The first adjusting component 3 tightens again to fix the sleeve 2, thereby realizing stepless angle adjustment and quick assembly / disassembly of the outrigger assembly 200.

[0035] Reference Appendix Figure 9 As shown, the support arm assembly 200 includes, from bottom to top, a first branch pipe 4 and a second branch pipe 5 that are nested together, and a second adjusting component 6 installed on the upper part of the first branch pipe 4 for adjusting the height and rotation angle of the second branch pipe 5; the bottom of the first branch pipe 4 is connected to the water outlet pipe section 21 via an adapter 7. When the support arm assembly 200 needs to be adjusted in height or rotation angle, the second adjusting component 6 is rotated outward to loosen the second branch pipe 5, pulled upward to move the second branch pipe 5, or rotated to rotate the second branch pipe 5, and then the second adjusting component 6 is tightened again.

[0036] Reference Appendix Figure 3-5 As shown, the water outlet component 1 has a water inlet cavity 14 at its first end 11, and at least one water outlet 15 is radially provided in the water inlet cavity 14. The outer wall of the water outlet component 1 is sequentially recessed with a first sealing ring groove 16, a water passage groove 17, and a second sealing ring groove 18 from the first end 11 to the second end 12. The first sealing ring groove 16 and the second sealing ring groove 18 are located on both sides of the water outlet 15. The water inlet of the water outlet pipe section 21 is correspondingly arranged with the water passage groove 17. The design of the water passage groove 17 allows water to flow smoothly into the water outlet pipe section 21 without needing to align the water outlet 15 with it. The first sealing ring groove 16 and the second sealing ring groove 18 are used to install sealing rings. The double sealing rings isolate the water passage groove 17 from the shower valve body 300, preventing leakage.

[0037] Reference Appendix Figure 6As shown, the first adjusting component 3 is threadedly connected to the first external thread section 13. The first adjusting component 3 includes a pressure ring 31 and a first rotating mechanism 32 for pressing the pressure ring 31 to adjust the tightness of the sleeve 2. The structure of the pressure ring 31 increases the contact area with the shower valve body 300, thereby evenly distributing the pressure and preventing the sleeve 2 from tilting. At the same time, the first rotating mechanism 32 provides a stable clamping force to prevent water flow impact from causing the sleeve 2 to shift angle and loosen. The first rotating mechanism 32 rotates the tube body 321 and the first handheld part 322. The rotating tube body 321 has a hollow structure and includes a clamping end for clamping the pressure ring 31 and a connecting end that is vertically and integrally connected to the first handheld part 322. The inner wall of the clamping end has an internal thread section 323 that mates with the first external thread section 13. The rotating tube body 321 has both threaded connection and clamping functions, reducing the number of parts. The first handheld part 322 provides a force application point, and rotation can tighten or loosen the sleeve, enabling one-handed operation.

[0038] In one specific embodiment, the number of water outlets 15 is two, and the two water outlets 15 are arranged opposite each other with the central axis of the water outlet component 1 as the axis of symmetry. The two water outlets 15 improve water discharge efficiency, and the symmetrical water outlets 15 disperse water flow impact, improve flow stability, and avoid surface cavitation noise caused by unilateral water discharge. In another specific embodiment, the number of water outlets 15 is four, and the four water outlets 15 are arranged opposite each other in pairs with the central axis of the water outlet component 1 as the axis of symmetry. The number of water outlets 15 can also be three, five, etc.

[0039] Reference Appendix Figure 4 , 7 As shown in Figure 8, the outer wall of the water outlet component 1 is provided with an external gear ring 19, which is located between the second sealing ring groove 18 and the first external thread section 13; the inner wall of the sleeve 2 is provided with an internal gear ring 22 that meshes with the external gear ring 19. The gear ring can provide segmented angle adjustment (e.g., 5° increments). The gear ring engagement and threaded clamping provide double locking to ensure that the sleeve 2 does not shift under vibration and water flow impact. When assembling the water outlet component 1 and the sleeve 2, the first external thread section 13 of the water outlet component 1 is inserted into the sleeve 2. After adjusting the predetermined angle of the water outlet pipe section 21, the external gear ring 19 and the internal gear ring 22 engage to prevent the water outlet component 1 and the sleeve 2 from rotating accidentally. Then, with the cooperation of the first adjusting component 3, a stable connection between the water outlet component 1 and the sleeve 2 and the angle adjustment of the support arm assembly 200 are achieved.

[0040] This utility model adapter 100 integrates functions, including angle adjustment, leak-proof sealing, and water flow guidance into a compact structure, which highly meets the requirements of the concealed shower valve body 300; the angle adjustment and fixing of the sleeve 2 can be completed by one-handed rotation operation, without the need for tools, which is user-friendly.

[0041] Reference Appendix Figure 9-14As shown, the second adjusting component 6 includes a limiting collar 61, a C-shaped buckle 62, and a second rotating mechanism 63. A limiting protrusion 611 is formed in the middle of the inner wall of the limiting collar 61. The limiting collar 61 includes a first sleeve section 612 located above the limiting protrusion 611 and a second sleeve section 613 located below the limiting protrusion 611. The C-shaped buckle 62 is installed in the first sleeve section 612 and abuts against the top surface of the limiting protrusion 611. When the second rotating mechanism 63 is tightened, the C-shaped buckle 62 contracts radially to prevent it from slipping off the ground and to ensure stability under shower vibration. The top end of the first branch pipe 4 abuts against the bottom surface of the limiting protrusion 611 and is screwed to the second sleeve section 613. The first sleeve section 612 passes through radially to form at least one threaded hole 614 for the second rotating mechanism 63 to screw in and press the C-shaped buckle 62. The second rotating mechanism 63 includes a second external threaded section 631 and a second handheld part 632, with the second external threaded section 631 perpendicularly connected to the second handheld part 632. Loosening the second rotating mechanism 63 outwards unlocks the C-shaped retaining ring 62, allowing the second branch pipe 5 to be inserted and removed for height adjustment or rotation angle adjustment. Tightening the second rotating mechanism 63 inwards then presses the C-shaped retaining ring 62, thus re-locking the height and horizontal angle of the second branch pipe 5. Preferably, the number of threaded holes 614 is any one of 2, 3, or 4, and the multiple threaded holes 614 are distributed in a circumferential array. The second external threaded section 631 can be screwed into any one of the threaded holes 614, increasing ease of operation.

[0042] Preferably, the adapter 7 includes an upper sleeve portion 71, a convex ring portion 72, and a lower threaded portion 73 in sequence; the bottom of the first branch pipe 4 is sleeved on the outer wall of the upper sleeve portion 71 and abuts against the convex ring portion 72, and the lower threaded portion 73 is threadedly connected to the water outlet pipe section 21; the adapter 7 forms a water passage 74 along the central axis. At least one third sealing ring groove 75 is provided on the outer wall of the upper sleeve portion 71; at least one fourth sealing ring groove 55 is provided on the lower outer wall of the second branch pipe 5. The sealing ring on the third sealing ring groove 75 prevents water from seeping downward at the connection between the adapter 7 and the first branch pipe 4; when the second branch pipe 5 extends, retracts, and rotates, the sealing ring on the fourth sealing ring groove 55 prevents water from seeping upward at the connection between the first branch pipe 4 and the second branch pipe 5.

[0043] Preferably, the second branch pipe 5 includes a vertical pipe 51, a first bent pipe 52, a horizontal pipe 53, and a second bent pipe 54 connected in sequence; the fourth sealing ring groove 55 is formed on the lower outer wall of the vertical pipe 51.

[0044] This utility model features a multi-angle adjustable water outlet arm that integrates three-dimensional adjustment of pitch angle, height, and horizontal rotation to accommodate different user heights and usage habits. Through the coordinated operation of the adapter 100 and the arm assembly 200, the adapter 100 adjusts the pitch angle of the arm assembly 200, and the arm assembly 200 can extend and retract to adjust its height and rotate 180° horizontally, achieving three-dimensional angle adjustment of the overhead shower head. All adjustments are completed by rotating the handheld component, requiring no tools for disassembly and assembly, thus achieving user-friendly operation.

[0045] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
