The back-up ring being fixed therein on wall is provided with the internal thread side of vertical cylinder, sealing ring, the sealing are fixed with the back-up ring
Circle is near straight tube and the nozzle of vertical cylinder.
Preferably, the straight tube outer wall be provided with its integrally formed protrusion cylinder, protrusion cylinder it is internal with straight tube in
Portion connects, and the protrusion cylinder is provided with baffle plate away from one end of straight tube, and the protrusion cylinder is identical with the axial line of vertical cylinder, described convex
Go out an inner diameter more than vertical cylinder outer diameter.
Preferably, straight tube side outer end is fixed with block, and the block is located in straight tube.
Preferably, the vertical cylinder outer end is provided with the nut being threadedly coupled with it, and the nut is located at straight tube outer end.
Preferably, the outer end of the vertical cylinder is provided with handle, and the handle is located at straight tube outer end.
Compared with prior art, the beneficial effects of the utility model are：The utility model is telescopic by vertical cylinder
Design, reaches its internal fixed pipe easy to disassemble, then reaches and is easy to rotate straight tube, removes the pipe at straight tube two ends, and
And sealing ring is with the addition of on the pipe fitting, can effectively prevent leak between pipe fitting and pipe.

Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings：
As shown in Figure 1 and Figure 2, inside a kind of flexible pipe fitting, including straight tube 1 and vertical cylinder 2, the straight tube 1 and vertical cylinder 2
The internal thread for being connected with pipe is provided with,
The outer end of vertical cylinder 2 is provided with external screw thread 21, and it is internal and mutual that the vertical cylinder 2 extends to it from the outer end of straight tube 1
Threaded connection；The outer end of vertical cylinder 2 is provided with the fixed block 3 being threadedly coupled with it, and the fixed block 3 is integrally formed with straight tube 1；
The internal thread side of the straight tube 1 and vertical cylinder 2 is provided with the back-up ring 8 being fixed therein on wall, solid on the back-up ring 8
Surely there is sealing ring 9, the sealing ring 9 is near straight tube 1 and the nozzle of vertical cylinder 2.
The outer wall of the straight tube 1 is provided with and connects inside the inside of cylinder 6 and straight tube 1 with its integrally formed protrusion cylinder 6, described protrusion
Logical, the protrusion cylinder 6 is provided with baffle plate away from one end of straight tube 1, and the protrusion cylinder 6 is identical with the axial line of vertical cylinder 2, described convex
Go out the inner diameter of cylinder 6 more than the outer diameter of vertical cylinder 2.
The side outer end of the straight tube 1 is fixed with block 7, and the block 7 is located in straight tube 1.
The outer end of vertical cylinder 2 is provided with the nut 5 being threadedly coupled with it, and the nut 5 is located at the outer end of straight tube 1.
The outer end of the vertical cylinder 2 is provided with handle 4, and the handle 4 is located at the outer end of straight tube 1.
Operation principle：Because one end of vertical cylinder 2 and straight tube 1 are respectively fixed at two ends with a pipe, in dismounting straight tube 1
Pipe when, the pipe that must be allowed first in vertical cylinder 2 and vertical cylinder 2 is separated, and then rotates the pipe that straight tube 1 removes its two ends,
So when removing the pipe on vertical cylinder 2, vertical cylinder 2 is rotated by handle 4, allow vertical cylinder 2 to be moved toward protrusion cylinder 6 direction, make
