[0030] Please see Figure 2 and Figure 4 The water pipe connector includes a plug 10, a connector 20, and a movable shaft 30. The movable shaft 30 is movably inserted into the connector 20 and has a connecting section that exposes the connector 20. The connecting section is connected to the plug 10. The end of the connector 20 away from the plug 10 has a connecting portion 201.
[0031] The connector 10 is configured to fix the water pipe.
[0032] In the technical solution of this utility model, the water pipe connector is used to connect the water pipe to the faucet, water gun and other structures. The plug 10 of the water pipe connector is used to insert into the end of the water pipe, and the connector 20 is used to connect the faucet, water gun and other structures. When the movable shaft 30 and the plug 10 are connected by rotation, the movable shaft 30 is in a rotatable state in the connector 20. Because the torque generated when connecting the water pipe to the faucet, water gun and other structures can be offset by the movable shaft 30, the problem of the water pipe getting tangled or knotted due to torque is avoided.
[0033] It is understood that the water pipe connector proposed in this utility model can be used as a male or female connector. When the water pipe connector is a male connector, the connecting part 201 has an external thread, which can be used to connect structures with internal threads such as water guns; when the water pipe connector is a female connector, the connecting part 201 has an internal thread, which can be used to connect structures with external threads such as faucets. Furthermore, regardless of whether it is used as a male or female connector, the water pipe connector has a movable shaft 30. When the water pipe connector connects the water pipe to the external structure, the rotatable movable shaft 30 counteracts the torque generated during installation, preventing the water pipe from tangling. Specifically, the plug 10, the connector 20, and the movable shaft 30 are all hollow structures, and the three together form a water passage to realize the flow of water. Among them, the movable shaft 30 has a hollow internal structure. The substructure passes through the connector 20 to form a connecting section that exposes the connector 20. The connecting section is fixedly inserted into the plug 10 by a threaded structure. Taking the female connector as an example, the plug 10 is first fixedly inserted into the water pipe, and the connector 20 is connected to the faucet. Then, the plug 10 and the connecting section are aligned and screwed into the lower part of the connecting section by the threaded structure. During this process, the torque is offset because the movable shaft 30 is rotatable. Alternatively, after the water pipe connector is assembled, the plug 10 is fixedly inserted into the water pipe. Because the movable shaft 30 and the plug 10 are movable by the threaded structure, and the connector 20 is movable relative to the movable shaft 30, the torque generated during the process of screwing the connector 20 into the faucet is insufficient to rotate the movable shaft 30, so that the connector 20 can offset the torque.
[0034] In one embodiment, please refer to Figure 2 The outer peripheral wall of the movable shaft core 30 is provided with a first step 301, and the inner peripheral wall of the connector 20 is provided with a second step 202 adapted to the first step 301. At this time, the water pipe connector is a female connector. When the movable shaft core 30 is inserted into the connector 20, the first step 301 abuts against the second step 202, thereby realizing the positioning of the movable shaft core 30. Furthermore, the first step 301 is uniformly raised along the outer peripheral wall of the movable shaft core 30 to form a ring structure. In this way, the first step 301 can abut against the inner peripheral wall of the connector 20 360 degrees, thereby avoiding the movable shaft core 30 from being eccentric in the connector 20.
[0035] In another embodiment, please refer to Figure 4The outer peripheral wall of the movable shaft core 30 is provided with a first step 301, and the inner peripheral wall of the connector 20 is provided with a second step 202 adapted to the first step 301. The first step 301 and the second step 202 are spaced apart to form a clearance space. The clearance space has multiple balls 40. The balls 40 abut against the first step 301 and the second step 202. At this time, the water pipe connector is a male connector. When the movable shaft core 30 is inserted into the connector 20, the first step 301 abuts against the balls 40. In this way, the contact area between the movable shaft core 30 and the connector 20 can be reduced by the balls 40, and the movable shaft core 30 can rotate easily.
[0036] Further, please refer to Figure 2 and Figure 4 To prevent the ball bearing 40 from "running" in the connector 20, the second step 202 has a limiting groove that connects to the clearance space. The ball bearing 40 is located in the limiting groove and part of the structure is located in the clearance space. Multiple balls bearing 40 are locked together in the limiting groove, thereby achieving the limiting and fixing of the ball bearing 40.
[0037] In one embodiment of this utility model, the water pipe connector further includes a sealing ring. The outer peripheral wall of the movable shaft core 30 has a sealing groove 30a. The sealing ring is engaged in the sealing groove 30a and abuts against the inner peripheral wall of the connector 20. The sealing groove 30a can be located above or below the first step 301, which is not limited here. The sealing ring can separate the gap between the inner peripheral wall of the connector 20 and the outer peripheral wall of the movable shaft core 30, so as to prevent water from seeping out of the water pipe connector.
[0038] Furthermore, the water pipe connector also includes a sealing baffle, which is a ring-shaped structure with a hollow center to ensure that the water passage is not blocked, reducing the cross-sectional area of the flow and ensuring that the water can flow smoothly from the faucet to the outlet device; there is a sealing gap 30b between the bottom wall of the connecting section facing away from the connector 20 and the plug 10, and the sealing baffle is engaged in the sealing gap 30b.
[0039] In one embodiment, please refer to Figure 4 When the water pipe connector is a male connector, the connector 20 includes a plug 21 and a fixed seat 22. The upper part of the movable shaft 30 is movably inserted into the plug 21, and the fixed seat 22 is fixedly connected to the plug 21. The lower part of the movable shaft 30 passes through the fixed seat 22 to form a connecting section. The inner peripheral wall of the fixed seat 22 is provided with an internal thread, and the outer peripheral wall of the plug 21 is provided with an external thread. The internal and external threads are connected to realize the fixed connection between the plug 21 and the fixed seat 22. The fixed seat 22 forms a second step 202. The first step 301 of the movable shaft 30 is located between the bottom of the plug 21 and the ball 40, thereby realizing the mobility of the movable shaft 30. The end of the plug 21 away from the fixed seat 22 has a connecting part 201, and the connecting part 201 is an external thread.
[0040] In another embodiment, please refer to Figure 2 When the water pipe connector is a female connector, the connecting part 201 is an internal thread.
[0041] Further, please refer to Figure 2 and Figure 4 The outer peripheral surface of the connector 10 has a fixing part 11 and a limiting part 12. The fixing part 11 is disposed near the connector 20 relative to the limiting part 12. The fixing part 11 has an external thread. The limiting part 12 includes a plurality of limiting protrusions arranged sequentially along the length direction of the connector 10. The cross-section of each limiting protrusion gradually decreases from the direction near the movable shaft core 30 to the direction away from the movable shaft core 30, so that the outer peripheral surface of the limiting protrusion is a conical surface. Each pair of adjacent limiting protrusions forms a limiting step. In this way, the connector 10 can be inserted into the water pipe while also preventing it from being pulled out, thus avoiding the connector 10 from being pushed out under water pressure. The fixing part 11 can be used to connect a protective sleeve on the water pipe. When using the water pipe to flush, the protective sleeve can be held to improve the grip.
[0042] This utility model also proposes a water pipe, which includes a pipe body and a water pipe connector. A portion of the connector 10 is inserted into the end of the pipe body and fixedly connected to the inner wall of the pipe body. The pipe body is fitted with a protective sleeve, which is fixedly connected to the connector 10. The specific structure of the water pipe connector is as described in the above embodiments. Since the water pipe proposed in this utility model adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.
[0043] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
