The end of the hinge joint facing the hinged sleeve has an internal threaded hole communicating with the water passage port. The hinged sleeve has a hinge joint facing the hinge joint and a hinge joint away from the hinge joint. The inner wall is provided with an internal gear ring and a support hole larger than the inner diameter of the hinge sleeve; the external threaded joint of the water distribution shaft is inserted from one end of the support hole, passes through the internal threaded hole of the hinge sleeve and the hinge joint, and screws into it, so that the axial position of the water passage hole corresponds to the adjacent sealing ring; a support spring is provided between the shaft head and the end face of the support hole, so that the shaft head, under the push of the support spring, causes the hinge joint to move axially relative to the hinge sleeve, so that the external gear ring and the internal gear ring mesh to achieve circumferential constraint between the hinge sleeve and the hinge joint, or pushes the shaft head in the opposite direction to compress the support spring, so that the external gear ring and the internal gear ring separate to achieve unlocking of the circumferential constraint between the hinge sleeve and the hinge joint; the water passage port of one hinge joint is connected to a first connector; the water passage port of the other hinge joint is connected to a second connector or an extension tube.

[0005] The present invention is further configured such that an outer water passage groove is provided in the middle section of the journal between the adjacent sealing rings, and one end of the water distribution channel is located at the bottom of the outer water passage groove.

[0006] The present invention is further configured such that the bottom of the outer water tank is provided with a plurality of water distribution channels arranged at intervals along its circumferential direction.

[0007] The present invention is further configured such that thread adhesive is applied between the external threaded connector and the internal threaded hole.

[0008] The present invention is further configured such that the sealing ring is V-shaped or O-shaped, wherein when it is V-shaped, the V-shaped openings face each other.

[0009] The present invention is further configured such that one end of the shaft head facing away from the external threaded connector is provided with an internal hexagonal hole.

[0010] The present invention is further configured such that the axis of the hinge sleeve is set at an angle to the axis of the intermediate tube; the axes of the two hinge sleeves are parallel to each other or set at an angle on the projection plane of the intermediate tube in the axial direction.

[0011] The present invention is further configured such that the hinge joint having a second connector has a third connector on its outer wall, and a valve core mounting position is provided at the end away from the hinge sleeve, wherein a switching valve is provided in the valve core mounting position; the second connector is controlled by the switching valve to selectively communicate with the third connector or the internal threaded hole.

[0014] The beneficial effects of this utility model are: 1. When adjusting the angle, the hinge sleeve or hinge joint is pulled axially to move them apart while compressing the support spring. At this time, the outer gear ring and the inner gear ring separate, and the hinge sleeve and the hinge joint are released from circumferential constraints to achieve circumferential angle adjustment. After the adjustment is completed, the hinge sleeve and the hinge joint are released, and they return to their original positions under the elastic force of the support spring, forcing the outer gear ring and the inner gear ring to re-mesh. The circumferential degree of freedom between the hinge sleeve and the hinge joint is then re-constrained. Since the number of meshing teeth of the outer gear ring and the inner gear ring is large, the overall rigidity is strong, and it has the advantages of convenient and quick angle adjustment. 2. Water flows from the water passage port of one of the hinge joints through the internal threaded hole, water distribution channel, water passage hole, and intermediate pipe, and then flows out from the water passage hole of the other hinge sleeve, the water distribution channel of the other water distribution shaft, the internal threaded hole of the other hinge joint, and the water passage port, thus realizing the water delivery; the water distribution shaft is sealed by a sealing ring, which allows the hinge sleeve and the hinge joint to rotate relative to each other while preventing water from flowing through. 3. The top spray is used for water outlet, and the third connector is used to connect to the hand spray, and the switching between the top spray and the hand spray is controlled by the switching valve.

Detailed Implementation

[0025] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0026] Example 1 refer to Figures 1 to 9 ,like Figures 1 to 9The water outlet adapter shown includes a central pipe 10 and two hinged sleeves 20 connected to both ends of the central pipe 10. Each hinged sleeve 20 has a water passage hole 21 on its side wall, connecting the inner cavity of the hinged sleeve 20 to the central pipe 10. Each hinged sleeve 20 has a hinge joint 30 coaxially arranged with it. The hinge joint 30 has a water passage port 31 and also includes a water distribution shaft 40. The water distribution shaft 40 has a shaft head 41, a journal 42, an external gear ring 43, and an external threaded connector 44 arranged sequentially along its axial direction. The outer wall of the journal 42 has a set of spaced-apart sealing rings 421. A water distribution channel 45 is provided between the outer wall of the journal 42 and the end of the external threaded connector 44 between adjacent sealing rings 421. The end of the hinge joint 30 facing the hinged sleeve 20 has an internal threaded hole 32 communicating with the water passage port 31. The inner walls of the hinged sleeve 20 facing the hinge joint 30 and the end away from the hinge joint 30 are respectively provided with an internal gear ring 22 and a large... The support hole 23 is located within the inner diameter of the hinge sleeve 20; the external threaded connector 44 of the water distribution shaft 40 is inserted from one end of the support hole 23, passing through the internal threaded hole 32 of the hinge sleeve 20 and the hinge joint 30, and the axial position of the water passage hole 21 corresponds to the adjacent sealing ring 421; a support spring 50 is provided between the shaft head 41 and the end face of the support hole 23, so that the shaft head 41, under the push of the support spring 50, causes the hinge joint 30 to be axially displaced relative to the hinge sleeve 20, so that the external gear ring 43 and the internal gear ring 22 mesh, thereby constraining the circumferential direction between the hinge sleeve 20 and the hinge joint 30, or the shaft head 41 is manually pushed in the opposite direction to compress the support spring 50, thereby separating the external gear ring 43 and the internal gear ring 22, thereby unlocking the circumferential constraint between the hinge sleeve 20 and the hinge joint 30; the water passage port 31 of one hinge joint 30 is connected to a first connector 311; the water passage port 31 of the other hinge joint 30 is connected to a second connector 312 or an extension tube 60.

[0027] In the above structure, when adjusting the angle, the hinge sleeve 20 or hinge joint 30 is pulled axially, causing them to move away from each other while compressing the support spring 50. At this time, the outer gear ring 43 separates from the inner gear ring 22, and the hinge sleeve 20 and hinge joint 30 are released from circumferential constraints, thus achieving circumferential angle adjustment. After adjustment, the hinge sleeve 20 and hinge joint 30 are released, and under the elastic force of the support spring 50, they return to their original positions, forcing the outer gear ring 43 and inner gear ring 22 to re-mesh. The circumferential degree of freedom between the hinge sleeve 20 and hinge joint 30 is then re-constrained. The internal gear ring 22 has a large number of meshing teeth, so it has strong overall rigidity and the advantage of convenient and quick angle adjustment. The water flows from the water port 31 of one of the hinge joints 30 through the internal thread hole 32, the water distribution channel 45, the water passage hole 21, and the intermediate pipe 10, and then flows out from the water passage hole 21 of the other hinge sleeve 20, the water distribution channel 45 of the other water distribution shaft 40, the internal thread hole 32 of the other hinge joint 30, and the water port 31, thus realizing the water flow.
