Drawings
Fig. 1 is a schematic structural view of a rotary sealing structure of a water pipe rolling device according to an embodiment of the present invention;
fig. 2 is a schematic structural view of the central shaft and the central shaft mounting base in fig. 1.
The parts in the drawings are numbered as follows: 1. the water-proof sealing device comprises a hub, 2, an outer cylinder, 3, an inner cylinder, 4, a sealing ring, 5, a water through hole, 6, a central shaft mounting seat, 7, a central shaft, 8, a bottom shell, 9 and a pipe joint part.
Detailed Description
The invention will be further described with reference to the following drawings and examples:
example (b): referring to FIGS. 1-2:
a rotary sealing structure of a water pipe coiling device comprises a hub 1, wherein the hub 1 comprises an outer cylinder body 2 and an inner cylinder body 3 which are axially arranged, the outer cylinder 2 is positioned outside the inner cylinder 3, the outer cylinder 2 is coaxial with the inner cylinder 3, a central shaft 7 is arranged in the inner cylinder 3, the inner cylinder 3 can rotate around the central shaft 7, the central shaft 7 is hollow, a water through hole 5 for connecting a water pipe is arranged on the wall of the hollow part of the central shaft 7, a hollow bottom shell 8 is arranged at the lower part of the central shaft 7, the inside of the bottom case 8 communicates with the hollow inside of the center shaft 7, a pipe joint part 9 is provided on the wall of the bottom case 8, the pipe joint part 9 is communicated with the inside of the bottom shell 8, a plurality of annular sealing rings 4 are arranged on the outer wall of the central shaft 7, and the sealing rings 4 seal the gap between the inner cylinder 3 and the central shaft 7. The bottom shell 8 is mounted on the central shaft mounting seat 6.
