The rotating connection structure used in the existing rotating faucet generally includes a clamping ring, a first water pipe with a connecting head fixed thereto, and a second water pipe. The clamping ring is rotatably sleeved on the connecting head, and the second water pipe and the clamping ring are detachably fixed to enable the second water pipe to rotate relative to the first water pipe. The clamping ring and the second water pipe are usually fixed by a clamping protrusion and a through hole. The clamping protrusion is provided on the clamping ring and can elastically expand and contract to insert into or withdraw from the through hole. In order to achieve the elastic expansion and contraction of the clamping protrusion, a clearance groove is formed between the clamping ring and the outer wall of the connecting head for the clamping protrusion to elastically expand and contract. Generally, the clearance groove is provided on the outer wall of the connecting head. When installing or removing the second water pipe, there is a problem of mismatch between the clamping protrusion and the clearance groove. At this time, the clamping protrusion cannot be withdrawn from the through hole, which makes it inconvenient to disassemble and install the second water pipe. Utility Model Content

[0012] Furthermore, a third water pipe is installed at one end of the first water pipe away from the second water pipe. The third water pipe is used to connect to the water inlet device. A rotating connection structure of the above-mentioned water pipe is provided between the third water pipe and the first water pipe, so that the first water pipe drives the second water pipe and the water outlet nozzle to rotate relative to the third water pipe.
[0013] After adopting the above scheme, the beneficial effect of the utility model is that: by arranging the tightening section and the giving way section on the clamping ring, the inner side wall of the tightening section is fitted on the outer side wall of the connecting head, and a giving way area is formed between the inner side wall of the giving way section and the outer side wall of the connecting head, and a spring piece is formed on the side wall of the giving way section, and the spring piece protrudes from the side away from the connecting head to form a clamping bulge, which can facilitate the clamping bulge to achieve elastic expansion and contraction when the clamping ring is rotated to any angle, so that it can slide into or exit the through hole. When the clamping bulge exits the through hole, the limit between the second water pipe and the clamping ring is released, so as to facilitate the disassembly of the second water pipe and also facilitate the installation of the second water pipe.

[0024] like Figures 1 to 7As shown, the utility model provides a rotating connection structure of a water pipe, comprising a first water pipe 1, a second water pipe 2 and a clamping ring 3; a connector 4 is protruded at one end of the first water pipe 1, and the clamping ring 3 is C-shaped. The clamping ring 3 is rotatably sleeved on the connector 4, and one end of the second water pipe 2 is sleeved on the clamping ring 3. A limiting portion 41 is formed on the outer wall of the connector 4, and the limiting portion 41 is formed on the path of axial movement of the clamping ring 3, so as to limit the axial movement of the clamping ring 3 when the clamping ring 3 is sleeved on the connector 4; a first water passage is formed in the first water pipe 1, and the first water passage passes through the side wall of the connector 4, and a second water passage is formed in the second water pipe 2, so that when one end of the second water pipe 2 is sleeved on the clamping ring 3, the first water passage and the second water passage are connected.
[0025] Focus on combination Figure 4-6 As shown, the clamping ring 3 includes a clamping section 31 and a clearance section 32. The inner side wall of the clamping section 31 is attached to the outer side wall of the connector 4, and a clearance area 5 is formed between the inner side wall of the clearance section 32 and the outer side wall of the connector 4 (as shown in FIG. Figure 6 As shown), a spring piece 6 is formed on the side wall of the give way section 32. Specifically, a give way hole is formed on the side wall of the give way section 32, and the give way hole radially penetrates the side wall of the give way section 32. One section of the side wall of the give way hole extends in a direction parallel to the axial direction of the clamping ring 3 to form the spring piece 6. The spring piece 6 can elastically swing around the side wall of this section. The spring piece 6 protrudes from the side of the connector 4 to form a clamping protrusion 7. A through hole 21 is formed on the side wall of the second water pipe 2, so that when the second water pipe 2 is sleeved on the clamping ring 3, the spring piece 6 is used to elastically drive the clamping protrusion 7 to slide into the through hole 21, so that the second water pipe 2 and the clamping ring 3 are fixedly connected; when installing, one end of the second water pipe 2 When axially sleeved on the clamping ring 3, the inner wall of the second water pipe 2 radially pushes the elastic piece 6, causing the elastic piece 6 to swing toward the yield area 5 until the locking protrusion 7 is aligned with the through hole 21. The elastic piece 6 is reset and elastically drives the locking protrusion 7 to slide into the through hole 21, so that the second water pipe 2 and the clamping ring 3 are fixed; when disassembling, an external force presses the locking protrusion 7 from the outside of the second water pipe 2, driving the elastic piece 6 to swing toward the yield area 5, causing the locking protrusion 7 to slide out of the through hole 21, releasing the limit between the second water pipe 2 and the clamping ring 3, and at the same time pulling the second water pipe 2 axially, the second water pipe 2 can be disassembled. Furthermore, an inclined surface is formed on the surface of the locking protrusion 7 to facilitate sliding in or out of the through hole 21.
[0026] Focus on combination Figure 2 As shown, a slider 8 is provided on the connector 4, and the slider 8 is connected to the connector 4 by an elastic member 9. The elastic member 9 is used to elastically drive the slider 8 to slide radially away from the connector 4. The inner wall of the second water pipe 2 is surrounded by a plurality of arc-shaped grooves 22 (such as Figure 3As shown), when the second water pipe 2 rotates at different angles relative to the connector 4, the slider 8 slides into or out of one of the several arc-shaped grooves 22, so that when the slider 8 slides into one of the arc-shaped grooves 22, it is used to limit the circumferential rotation of the second water pipe 2; the elastic member 9 is specifically a spring. Specifically, a channel 44 is formed on the outer wall of the connector 4, and the channel 44 extends radially. One end of the spring is fixed in the channel 44, and the other end of the spring is fixed to the slider 8. The slider 8 can slide in the channel 44. When the spring is in a natural state, the slider 8 extends out of the channel 44. When the slider 8 is pressed, the spring is compressed, and the slider 8 slides into the channel 44. In other embodiments, the elastic member 9 can also be a spring or other elastic member; when in use, the second water pipe 2 is rotated, and the inner wall of the second water pipe 2 pushes against the slider 8 to compress the spring, so that the slider 8 slides into the channel 44 until it exits the arc-shaped groove 22, thereby releasing the circumferential limit on the second water pipe 2. When the second water pipe 2 continues to be rotated until one of the arc-shaped grooves 22 is aligned with the channel 44, the spring is reset, and the elastic force drives the slider 8 to slide outward to extend out of the channel 44, and the slider 8 slides into the arc-shaped groove 22. At this time, the external force is removed, and the rotation of the second water pipe 2 stops. The slider 8 forms a card connection with the arc-shaped groove 22 to limit the rotation of the second water pipe 2.
[0027] Focus on combination Figure 2 As shown, an annular groove 42 is formed around the outer wall of the connecting head 4, and the annular groove 42 is the limiting portion 41, so that when the snap ring 3 is sleeved in the annular groove 42, the inner wall of the tightening section 31 of the snap ring 3 fits against the inner wall of the annular groove 42, and the outer wall of the snap ring 3 is consistent with the contour of the outer wall of the connecting head 4, so that the snap ring 3 is embedded in the annular groove 42 to limit the axial movement of the snap ring 3.
[0028] When the clamping ring 3 is sleeved in the annular groove 42, the outer wall of the clamping ring 3 is consistent with the outline of the outer wall of the connector 4. After the second water pipe 2 is sleeved on the clamping ring 3, its inner wall is matched with the outer wall of the connector 4 at the same time. In order to ensure the sealing between the connector 4 and the second water pipe 2, at least one sealing groove 43 is arranged around the outer periphery of the connector 4. The sealing groove 43 and the annular groove 42 are arranged axially at intervals. A sealing ring 10 is sleeved in the sealing groove 43, so that after the second water pipe 2 is sleeved on the clamping ring 3, the sealing ring 10 is pressed against the inner wall of the second water pipe 2 to seal the connector 4 and the second water pipe 2. There are two sealing grooves 43. Of course, there can also be three or four in other embodiments, and there is no specific limitation.
[0029] Preferably, a convex rib 33 is formed on the outer wall of the tightening section 31, and the convex rib 33 is used to press against the inner wall of the first water pipe 1, so that an interference fit is formed between the clamping ring 3 and the second water pipe 2, making the structure more compact and firm, while reducing the processing accuracy requirements of the clamping ring 3 and reducing costs.
[0030] Focus on combination Figure 1 and Figure 7As shown, the utility model also provides a faucet, which uses the above-mentioned rotating connection structure of the water pipe, wherein the first water pipe 1 is a water inlet pipe, the first water pipe 1 is used to connect the water inlet device, the second water pipe 2 is a water outlet pipe, the second water pipe 2 is formed with a water outlet 11, and a water outlet nozzle 12 is installed on the water outlet 11, and the second water pipe 2 drives the water outlet nozzle 12 to rotate relative to the first water pipe 1.
[0031] Preferably, a third water pipe 13 is further installed at one end of the first water pipe 1 away from the second water pipe 2. The third water pipe 13 is used to connect to a water inlet device, which is an external water source. A rotating connection structure of the water pipe is provided between the third water pipe 13 and the first water pipe 1. When the first water pipe 1 rotates relative to the third water pipe 13, the second water pipe 2 and the water outlet nozzle 12 can be driven to rotate relative to the third water pipe 13. Further, as Figure 7 As shown, the third water pipe 13 is formed with the above-mentioned connector 3 at one end away from the first water pipe 1, and can also be rotatably connected with other water pipes for use in different occasions. Of course, in other embodiments, there can also be a variety of deformation structures to achieve rotational connection between multiple water pipes. Those skilled in the art can design it according to the specific situation.
