DETAILED DESCRIPTION

[0030] The sleeve type through-wall pipe waterproof structure will be further described in detail below in combination with the drawings and specific embodiments.

[0031] As Figures 1-3 shown, the sleeve type through-wall pipe waterproof structure of the utility model, including through-wall pipe 1, sleeve 2 of the sleeve set in the outside of through-wall pipe 1, the middle part and both sides of the pipe wall of sleeve 2 are provided with wing ring 3, and wall 7 is poured between the wing ring 3 of both sides of sleeve 2, the inner wall of sleeve 2 is provided with inner thread 201, and the both ends of sleeve 2 are threadedly matched with limiting end cover 4, the end of limiting end cover 4 that extends into wall 7 is fixed with stop ring 41 that is arranged towards the axis of through-wall pipe 1, one end of through-wall pipe 1 is sleeved with rubber ring 5, and the other end is sleeved with back-up ring 6, there is gap between limiting end cover 4 and through-wall pipe 1, rubber ring 5 and back-up ring 6 are all located in the gap, short pipe 9 is arranged on the outside of rubber ring 5 away from wall 7, short pipe 9 is sleeved in the gap between limiting end cover 4 and through-wall pipe 1, flange gland 10 is arranged on the end of short pipe 9 away from wall 7, flange gland 10 is fixed on wing ring 3 through connecting piece, the inner annular surface of stop ring 41 is in close contact with the outer wall of through-wall pipe 1, and in the axial direction of through-wall pipe 1, rubber ring 5 is located between stop ring 41 and short pipe 9.

[0032] In the embodiment, the connecting member comprises a threaded screw 11 and a nut 12. The screw 11 is a double-threaded screw, one end of which is embedded in the cast wall 7 to ensure that the screw 11 is stable after the wall 7 is cast and formed. A flange abutting hole is formed in the wing ring 3 close to the short pipe 9. The screw 11 passes through the flange abutting hole of the wing ring 3 and the flange hole of the flange gland 10. The nut 12 is threadedly connected with the screw 11. With the tightening of the nut 12, the flange gland 10 can press the rubber ring 5 against the short pipe 9, so that the rubber ring 5 is filled in the gap between the limiting end cover 4 and the through-wall pipe 1, thereby preventing water flow.

[0033] In the embodiment, the limiting end cover 4 comprises a cylinder 42, a check ring 41 and a ring cover 43. The cylinder 42 extends into the wall 7.
