Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

As shown in fig. 1, fig. 2, fig. 3, and fig. 4, an embodiment of the present invention provides a connection structure of a glass fiber plastic jacking pipe, including a first pipe body 1 and a second pipe body 2, a first connection member 3 is connected to a right side of the first pipe body 1 through a thread, a second connection member 4 is connected to a left side of the second pipe body 2 through a thread, a chute 5 is provided on a right side of the first connection member 3, fixing grooves 6 are provided around an outer side of the chute 5, a slip ring 7 is welded on a left side of the second connection member 4, stepped grooves 8 are provided around an inner wall of the slip ring 7, springs 9 are fixedly connected to bottom ends of inner walls of the stepped grooves 8, fixing blocks 10 are slidably connected to the stepped grooves 8, the fixing blocks 10 are wedge-shaped, and one ends of the springs 9 are fixedly connected to bottom ends of the fixing blocks 10.

The inner wall both sides of first body 1 and second body 2 have all seted up internal thread 11, and external screw thread 12 has all been seted up to the one end of first connecting piece 3 and second connecting piece 4, and the right side welding of first connecting piece 3 has sealing ring 13, and the left side of second connecting piece 4 has seted up seal groove 14, and the welding of the inner wall bottom of seal groove 14 has spring leaf 15, and spring leaf 15 upper end has pasted sealing washer 16 through the fixed glue.
