The cross-section that sets up reinforced pipe 200 is circular, and circular cross-section embedding body 100 recess 101 on the outer wall, and then increases the area of contact between reinforced pipe 200 and the body 100, when the atress, can reduce unit area of contact's atress to improve joint strength between them, the difficult production of junction between them is cracked.

Further, the cross section of the reinforcing pipe 200 is disposed in a semi-elliptical shape, and the bottom edge of the cross section of the reinforcing pipe 200 is attached to the outer wall of the pipe body 100.

The cross section of the reinforced pipe 200 is set to be semi-elliptical, so that the reinforced pipe 200 can bear larger force to improve the upper limit of the stress of the whole threaded pipe.

Further, the support 300 includes a plurality of reinforcing ribs parallel to each other, and each of the reinforcing ribs is perpendicular to the outer wall of the reinforcing tube 200.

When the support member 300 is pressed, the plurality of reinforcing ribs parallel to each other are independently stressed, and each reinforcing rib is perpendicular to the outer wall of the reinforcing pipe 200, so that the supporting direction and the stress direction of each reinforcing rib are approximately equal, and the supporting effect of the support member 300 is improved.

Further, the supporting member 300 includes a first reinforcing rib 310 and two second reinforcing ribs 320, both ends of the first reinforcing rib 310 are connected to the inner wall of the reinforcing pipe 200, one end of the second reinforcing rib 320 is connected to the inner wall of the reinforcing pipe 200, and the other end of the second reinforcing rib 320 is connected to the first reinforcing rib 310.

The first ribs 310 intersect with the second ribs 320, so that the first ribs 310 and the second ribs 320 form a whole, and when the first ribs 310 and the second ribs 320 are pressed, the first ribs 310 and the second ribs 320 are stressed together.
