Based on the embodiments described in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0030] The embodiments of the present application provide a water pipe anti-winding mechanism,Figures 1 to 8 As shown, it comprises a water outlet joint assembly and a water inlet joint assembly arranged at both ends of the water pipe 100, the water outlet joint assembly comprises a riveting sleeve 200, a sealing ring 300, an external tooth joint 400, a joint lining 500 and a circlip 600. The riveting sleeve 200 is arranged at the water outlet of the water pipe 100, specifically, one end of the riveting sleeve 200 is arranged outside the water pipe 100. The outer wall of the joint lining 500 is provided with a plurality of protruding rings, the protruding rings are formed in a barb shape, the joint lining 500 is inserted into the water outlet of the water pipe 100, and the joint lining 500 is a hollow pipe for water flow.

[0031] The top of the joint lining 500 is further provided with a sealing ring groove, and two sets of sealing grooves are arranged side by side above and below, and two sealing rings 300 are respectively sleeved and fixed in the sealing ring grooves.

[0032] The outer wall of the external tooth joint 400 is provided with threads. The top of the joint lining 500 is further provided with a limiting protrusion. The bottom of the external tooth joint 400 is provided with a sleeving ring, the sleeving ring is rotatably sleeved on the joint lining 500, and the limiting protrusion limits the sleeving ring from moving axially to the top of the joint lining 500. The top of the joint lining 500 is further provided with a clamping groove, and the clamping groove is externally fixed with the circlip 600. The circlip 600 is a C-shaped circlip 600, and the C-shaped circlip 600 abuts one end of the riveting sleeve 200. The C-shaped circlip 600 limits the sleeving ring from moving axially to the bottom of the joint lining 500. At this time, the external tooth joint 400 can rotate freely around the joint lining 500, and cannot be separated from the sleeving state in the axial direction.

[0033] The water inlet joint assembly comprises a riveting sleeve 200, a sealing ring 300, a water inlet nut 700, a joint lining 500, a water stop gasket 800 and a circlip 600. The riveting sleeve 200 is arranged at the water inlet of the water pipe 100, specifically, one end of the riveting sleeve 200 is arranged outside the water pipe 100. The outer wall of the joint lining 500 is provided with a plurality of protruding rings, the protruding rings are formed in a barb shape, and the joint lining 500 is inserted into the water inlet of the water pipe 100.

[0034] The top of the joint lining 500 is further provided with a sealing ring groove, and two sets of sealing grooves are arranged side by side above and below, and two sealing rings 300 are respectively sleeved and fixed in the sealing ring grooves.

[0035] The top of the joint liner 500 is further provided with a limiting protrusion. The bottom of the water inlet nut 700 is fixedly provided with a sleeving ring, which is rotatably sleeved on the joint liner 500, and the limiting protrusion limits the axial movement of the sleeving ring to the top of the joint liner 500. In the sleeving state, the bottom surface of the water inlet nut 700 is higher than the top surface of the joint liner 500.

[0036] The top of the joint liner 500 is further provided with a clamping groove, and the clamping groove is fixedly provided with the snap spring 600. The snap spring 600 is a C-shaped snap spring 600, which abuts one end of the riveting sleeve 200. The C-shaped snap spring 600 limits the axial movement of the sleeving ring to the bottom of the joint liner 500.

[0037] The water stop washer 800 is annular, and the outer wall of the water stop washer 800 is provided with a plurality of protrusions. The water stop washer 800 is clamped and arranged in the water inlet nut 700, and abuts the inner bottom of the water inlet nut 700. Since the top plane of the joint liner 500 is lower than the thread bottom surface of the water inlet nut 700, even if the thread is tightened and pressed to death by the washer after the spray gun or faucet, the water pipe 100 can still rotate freely.

[0038] The above design is not only suitable for the connection of spring water pipes, but also suitable for garden hoses, such as Figure 4 , and the like.
