Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, the present invention provides an embodiment: the utility model provides an antiseep FRP pipe says expansion joint, including connecting pipe main part 1, the outside fixed mounting of connecting pipe main part 1 has connecting body 2, the externally mounted of connecting pipe main part 1 has connecting pipe 4, the inside screw thread fixed mounting of connecting pipe 4 has expansion joint device 3, mounting flange 7 is installed to connecting body 2's both ends symmetry, mounting hole 5 has been seted up to equal even symmetry on mounting flange 7, the equal even symmetric connection in outside edge of mounting flange 7 has connecting block 6, screw thread fixed mounting has installation dead lever 8 between the connecting block 6, install solid fixed ring 9 among the expansion joint device 3, gu the ring 10 is twisted soon to fixed ring 9's both ends symmetry fixedly connected with, gu the mid-mounting of fixed ring 9 has screw thread fixed ring 11, gu fixed ring 9's inside is inlayed there is leak protection rubber ring 12, inside fixed screw thread 13 has been seted up.
