A flexible composite pipe is sealed and clamped between the inner core pipe 2 and the outer sleeve 1. An outer magnetic ring 3 is provided on one side of the outer wall of the inner core pipe 2. An inner magnetic ring 4 is provided on the inner wall of the outer sleeve 1 at a position corresponding to the outer magnetic ring 3. The outer magnetic ring 3 and the inner magnetic ring 4 are relatively tightly sealed. An adjustable sealing assembly is fixedly installed on the other side of the outer wall of the outer sleeve 1. The other side of the outer sleeve 1 is clamped to the flexible composite pipe through the adjustable sealing assembly.

[0021] The sealing inner ring section of the inner magnetic ring 4 and the sealing outer ring section of the outer magnetic ring 3 are both configured as fitted inclined surfaces.

[0022] A sealed cavity is provided between the sealed outer ring of the inner magnetic ring 4 and the sealed inner ring of the outer magnetic ring 3 in a sealed fitting state. An array of rubber sealing rings 5 ​​are staggered on both sides of the sealed cavity between the sealed outer ring of the inner magnetic ring 4 and the sealed inner ring of the outer magnetic ring 3. The array of rubber sealing rings 5 ​​is in a compressed state when in a sealed fitting state.

[0023] The outer sleeve 1 is vertically provided with a through hole 6 near the outer magnetic ring 3 in the sealed cavity, so that the flexible composite tube can discharge gas when entering between the inner core tube 2 and the outer sleeve 1, making installation more convenient.

The length of the rubber plug 7 is larger than the thickness of the outer sleeve 1. The rubber plug 7 can quickly fill and plug the through hole after the flexible composite pipe is installed, and can enhance the sealing effect under the test state.

[0025] The outer wall of the inner core tube 2 is provided with multiple groups of one-way inclined grooves 8 at equal intervals. The opening directions of the multiple groups of one-way inclined grooves 8 face the inner magnetic ring 4 to increase the friction force of the flexible composite tube.

The worm 12 is rotatably provided in the mounting ring seat 9. One end of the worm 12 passes through the mounting ring seat 9 and is provided with a cross slot. The cross slot can be used to facilitate manual adjustment of the adjusting sealing assembly. The worm 12 is rotated by a tool to drive the adjusting ring plate 11 to rotate, thereby driving multiple groups of adjusting ring plates 11 to move relative to each other, thereby clamping the outer wall of the flexible composite pipe, so that the inner wall of the flexible composite pipe is sealed with the outer wall of the inner core pipe 2.

[0028] The inner side of the adjusting ring plate 11 is arranged outside the inner wall of the outer sleeve 1 at the minimum stroke, so as to avoid affecting the insertion of the flexible composite pipe at the minimum stroke.

[0029] The utility model has the advantages of being able to quickly achieve sealing clamping of both ends of the flexible composite pipe, having a good clamping and sealing effect, and fully meeting the testing needs. At the same time, the test joint can be reused, thus reducing waste and lowering costs.
