[0007] A water sealing kit is arranged in the plug port, and a plurality of adjusting rings are stacked in the water sealing kit;

[0008] A collar connected to the base at one end of the plug interface;

[0009] When the faucet is plugged into the plug port, the sleeve ring is driven to move toward the bottom of the plug port and squeeze the water sealing structure to make the water sealing kit or the adjusting ring have an interference fit with the faucet.

[0010] In the universal joint as described above, the radius values ​​of the plurality of adjustment rings increase sequentially from the inside to the outside.

[0011] In the universal joint as described above, the adjustment ring includes a first adjustment ring and a second adjustment ring stacked outside the first adjustment ring.

[0012] In the universal joint as described above, the water sealing structure includes a plurality of water sealing ribs arranged in sequence along the circumference of the outer end surface of the plug-in port.

[0013] In the universal joint as described above, the outer side wall of the water sealing rib is also provided with an inclined surface which cooperates with the inner side wall of the sleeve ring.

[0014] In the universal connector as described above, the base is further provided with an inner thread connection port at one end away from the plug port, and the inner thread connection port is connected with inner threads.

[0015] In the universal joint as described above, one end of the water sealing kit is further provided with an internal thread water sealing part which can be placed in the internal thread connection port, and the outer end surface of the internal thread water sealing part is interference fit with the internal thread.

[0016] In the universal joint as described above, a limiting convex ring is further protruded outwardly on the outer end surface of the inner thread water sealing part, and a limiting groove capable of cooperating and engaging with the limiting convex ring is further provided on the inner side wall of the inner thread connecting port.

[0017] In the universal joint as described above, the water sealing kit and the adjusting ring are both made of silicone.

[0018] In the universal joint as described above, the water sealing structure is made of polypropylene.

[0019] The beneficial effects of the present invention are as follows: the present invention has a simple structure. When connecting, after the water nozzle is plugged into the plug interface, the driving ring moves toward the bottom of the plug interface and squeezes the water sealing structure to make the water sealing kit or the adjusting ring have an interference fit with the water nozzle, thereby achieving a good sealing effect and avoiding the occurrence of leakage, bubbling, dripping and leaking. Moreover, according to the actual situation, the adjusting ring can be freely selected for use (when the outer diameter of the water nozzle is larger, the number of adjusting rings can be reduced or the adjusting ring can be directly not used; when the outer diameter of the water nozzle is smaller, the number of adjusting rings can be increased), without the need to replace the entire joint, so it has a wide range of applicability and is practical and convenient.

[0028] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] See also Figures 1 to 7 As shown, the embodiment of the present application provides a universal connector, including:

[0030] The base 1 has a plug-in port 10 at one end thereof for connecting to a water nozzle, and a water sealing structure 2 is also provided on the peripheral side of the outer end surface of the plug-in port 10;

[0031] A water sealing kit 3 is arranged in the plug port 10, and a plurality of adjusting rings 30 are stacked in the water sealing kit 3;

[0032] A collar 4 connected to the base 1 at one end of the plug port 10;

[0033] When the faucet is plugged into the plug port 10 , the sleeve ring 4 is driven to move toward the bottom of the plug port 10 and squeeze the water sealing structure 2 to make the water sealing kit 3 or the adjusting ring 30 interference fit with the faucet.

[0034] When connecting, after the faucet is inserted into the plug port 10, the driving ring 4 is moved toward the bottom of the plug port 10 and the water sealing structure 2 is squeezed to make the water sealing kit 3 or the adjusting ring 30 have an interference fit with the faucet, thereby achieving a good sealing effect and avoiding the phenomenon of running, bubbling, dripping and leaking. According to the actual situation, the adjusting ring can be freely selected for use (when the outer diameter of the faucet is larger, the number of adjusting rings 30 can be reduced or the adjusting ring 30 can be directly not used; when the outer diameter of the faucet is smaller, the number of adjusting rings 30 can be increased), without the need to replace the entire joint, it has wide applicability, is practical and convenient.

[0035] In this embodiment, the radius value of the water sealing kit 3 can be set to match the maximum outer diameter value in the commonly used water faucet specifications, such as 24 mm.

[0036] Furthermore, the radius values ​​of the plurality of adjustment rings 30 are increased from the inside to the outside. The radius values ​​of the plurality of adjustment rings 30 are set in increments, which facilitates the adjustment of the number of adjustment rings 30 and is practical and convenient.

[0037] In this embodiment, the adjustment ring 30 includes a first adjustment ring 301 and a second adjustment ring 302 stacked outside the first adjustment ring 301 .

[0038] Furthermore, the water sealing structure 2 includes a plurality of water sealing ribs 21 arranged in sequence along the circumference of the outer end surface of the plug port 10 .

[0039] Specifically, an inclined surface 22 for cooperating with the inner wall of the collar 4 is formed on the outer wall of the water sealing rib 21 .

[0040] By providing the inclined surface to cooperate with the inner wall of the collar 4, the sliding contact between the water sealing rib 21 and the collar 4 is smoother, and the tightening process is more convenient.

[0041] Specifically, the water sealing structure 2 is made of elastic material, so that the water sealing structure 2 can be moved more smoothly and can be smoothly restored to its original position after use, which is practical and convenient.

[0042] In this embodiment, the material of the water sealing structure 2 is PP (polypropylene).

[0043] Furthermore, the base 1 is further provided with an inner thread connection port 11 at one end away from the plug port 10, and the inner thread connection port 11 is connected with an inner thread 5. Connecting to the water-using equipment through the inner thread 5 is a common prior art in the art.

[0044] Furthermore, one end of the water sealing kit 3 is also provided with an inner thread water sealing part 300 that can be placed in the inner thread connection port 11, and the outer end surface of the inner thread water sealing part 300 is interference fit with the inner thread 5. Through the interference fit between the inner thread water sealing part 300 and the inner thread 5, the sealing performance of the joint is further improved, and the phenomenon of running, bubbling, dripping and leaking is further avoided. At the same time, the use of the inner thread silicone pad can be reduced, which is practical and convenient.

[0045] Specifically, a limiting convex ring 61 is protruded outwardly on the outer end surface of the inner thread water sealing part 300, and a limiting groove 62 capable of engaging with the limiting convex ring 61 is provided on the inner side wall of the inner thread connection port 11. This can greatly reduce the occurrence of the water sealing kit 3 being separated from the base 1, which is practical and convenient.

[0046] In this embodiment, the water sealing kit 3 and the adjusting ring 30 are both made of silicone.

[0047] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure made using the contents of the specification and drawings of the present invention, or directly or indirectly used in other related technical fields, is also included in the patent protection scope of the present invention.
