[0036] like Figures 1-8 As shown in the figure, as an embodiment of the present invention, a pipe connection structure is provided, including a long pipe connector 1, a short pipe connector 2, and a support and limiting member 3. The long pipe connector 1 includes a first sleeve 11, a first support seat 12 connected to one end of the first sleeve 11, a second support seat 13 connected to the other end of the first sleeve 11, and a first connector 14 for connecting an external long pipe connector, located near the first support seat 12 and connected to the side of the first sleeve 11. The first connector 14 has a first connecting channel 141 communicating with the first sleeve 11. The short pipe connector 2 includes a second sleeve 21 rotatably fitted onto the first sleeve 11, and a second connector 22 for connecting an external short pipe connector, connected to the side of the second sleeve 21 away from the first support seat 12. The second connector 22 has a second connecting channel 221 communicating with the second sleeve 21, and a first limiting seat 211 is provided along its outer periphery on the second sleeve 21. The support limiting member 3 is rotatably sleeved on the second sleeve 21 and limited on the first limiting seat 211 on the side away from the first support seat 12. It is fixedly connected to the second support seat 13. The support limiting member 3 can rotate with the long pipe connector 1 relative to the short pipe connector 2. When water is sent from the short pipe to the long pipe, the internal water flow will generate outward water pressure between the long pipe connector 1 and the short pipe connector 2, fixing the long pipe connector 1 and the support limiting member 3 together to connect the long pipe. After the short pipe connector 2 and the support limiting member 3 are integrated, the impact pressure brought by the water flow can be effectively reduced, the deformation between the two water pipe connectors can be reduced, and the outer shell will not be damaged, making the overall structure more stable and stronger.

[0037] As shown in Figure 2 , the second sleeve 21 extends into the first sleeve 11 and is rotatably sleeved with the first sleeve 11, and after sleeving, the second connecting channel 221 and the first connecting channel 141 can communicate. One or more sealing rings (not shown in the figure) are arranged outside the second sleeve 21 between the second sleeve 21 and the first sleeve 11, so that the water flow or other liquid flowing between the two water pipe connectors does not leak, avoiding liquid erosion of functional components and prolonging the service life of the pipe winder.

[0038] As shown in Figure 4 and Figure 5 , the second support seat 13 is arranged along the outer circumferential side of the first sleeve 11 and extends outward from the outer side wall of the first sleeve 11. A plurality of second assembly channels 31 corresponding to the second assembly channels 131 are arranged on the support limiting piece 3. The support limiting piece 3 and the second support seat 13 are connected by the second assembly piece (not shown in the figure) fitted in the corresponding second assembly channel 131 and second assembly channel 31. The support limiting piece 3 and the second support seat 13 are fixed by the second assembly piece 6, further enhancing the connection stability between the long pipe connector 1 and the short pipe connector 2, making the structure more stable and increasing the structural practicability.

[0039] As shown in Figure 5 and Figure 10 , the first support seat 12 is arranged along the outer circumferential side of the first sleeve 11 and extends outward from the outer side wall of the first sleeve 11. A plurality of first assembly channels 41 corresponding to the first assembly channels 41 on the outer winding wheel 4 are arranged on the first support seat 12. The first support seat 12 can be connected with the outer winding wheel 4 by the first assembly piece (not shown in the figure) fitted in the corresponding first assembly channel 121 and first assembly channel 41. After connection, the long pipe connector 1 and the winding wheel 4 can rotate synchronously. The second assembly channel 131 and the first assembly channel 121 are arranged in a staggered manner. A plurality of assembly channels 132 for disassembling the first assembly piece 5 are arranged on the second support seat 13 corresponding to the first assembly channel 121, which facilitates the insertion of tools during assembly and increases the structural practicability.

[0040] As shown in Figure 5 , the assembly channel 132 is arranged close to the outer circumferential edge of the second support seat 13. The outer circumferential side of the second support seat 13 is provided with a notch communicating with the assembly channel 132, which facilitates the insertion of tools during assembly and increases the structural practicability.

[0042] As shown in Figure 7 , the support limiting piece 3 is provided with a sleeve connection channel 34 and an installation channel 35, the second sleeve 21 is rotatably sleeved in the sleeve connection channel 34, so that the short pipe connecting piece 2 can not need to rotate when the support limiting piece 3 and the long pipe connecting piece 1 rotate. The installation channel 35 extends from the outer circumferential side of the support limiting piece 3 to the installation channel 35 and communicates with the installation channel 35, and the second sleeve 21 can extend into the sleeve connection channel 34 along the installation channel 35, facilitating the connection of the second sleeve 21 and the support limiting piece 3 and increasing the practicability.

[0043] As shown in Figure 7 and Figure 8 , the channel width of the installation channel 35 at the end connected with the sleeve connection channel 34 is less than the diameter of the sleeve connection channel 34, and the diameter of the second sleeve 21 is consistent with the sleeve connection channel 34, so that the first sleeve 11 can be installed in the limited sleeve connection channel 34 and will not be separated from the installation channel 35 when rotating. The installation channel 35 has a first side wall 351 and a second side wall 352 arranged oppositely, and the distance between the first side wall 351 and the second side wall 352 gradually increases from the end close to the installation channel 35 to the end close to the outer circumferential side of the support limiting piece 3. In the present embodiment, the support limiting piece 3 is a plastic part with a certain deformation ability, and the arrangement of the first side wall 351 and the second side wall 352 can facilitate the installation of the second sleeve 21 and the sleeve connection channel 34 and increase the structural practicability.

[0044] As shown in Figure 4 , Figure 6 and Figure 8As shown, the second sleeve 21 is provided with a second limiting seat 212 along its outer peripheral side, which is arranged at a side away from the first limiting seat 211 and away from the first support seat 12, and the support limiting piece 3 is limited between the first limiting seat 211 and the second limiting seat 212, so that after the second sleeve 21 is sleeved with the first sleeve 11, the first sleeve 11 and the second sleeve 12 are fixed by the first and second limiting seats and the support limiting piece 3, and will not be axially deviated under the pressure of water flow, a plurality of sealing grooves 214 for storing sealing rings are arranged at the lower side of the second limiting seat 212, the sealing rings are positioned, displacement deviation is reduced under the action of hydraulic pressure, liquid leakage is prevented, and the resistance between the first sleeve 11 and the second sleeve 12 is increased to prevent disengagement.

[0045] In another embodiment, as shown in Figure 9 and Figure 10 A pipe coiling device includes a pipe connecting structure 7 and a housing 8, a coiling wheel 4 rotatably arranged in the housing, a short pipe, and a long pipe coiled on the coiling wheel 4, a first connecting head 14 arranged in the housing and communicating with an inlet end (not shown in the figure) of the long pipe, a second connecting head 22 arranged outside the housing and communicating with an outlet end (not shown in the figure) of the short pipe, a first support seat 12 arranged in the housing and fixedly connected to one side of the coiling wheel 4, and a support limiting piece 3 arranged outside the housing. A first connecting opening 142 communicating with a first connecting channel 141 is formed at an end of the first connecting head 14 away from the first sleeve 11, and a first sleeve opening 112 communicating with the first connecting channel 141 is formed at an end of the first sleeve 11 close to the second support seat 13. A second connecting opening 22 communicating with a second connecting channel 221 is formed at an end of the second connecting head 22 away from the second sleeve 21, and a second sleeve opening 213 communicating with the second connecting channel 221 is formed at an end of the second sleeve 21 close to the first sleeve 11, so that water flow can enter the long pipe from the short pipe smoothly.
