Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a pyrocondensation pipe for optic fibre is fixed, moulds pipe 2 including first thermoplasticity pipe 1 and second thermoplasticity, it has hot melt adhesive layer 3 all to fill in the inner chamber of pipe 2 is moulded to first thermoplasticity pipe 1 and second thermoplasticity, evenly be equipped with optic fibre 4 in the inner chamber of pipe 2 is moulded to first thermoplasticity pipe 1 and second thermoplasticity, be equipped with interior dismantlement between pipe 2 and mould pipe 5 with the thermoplasticity through interior dismantlement, connect with thermoplasticity pipe 5 through interior dismantlement to through closing plate 9 as connecting the reinforcing plate, improve the dynamics of connection.

The top of the thermoplastic pipe for internal disassembly 5 is bonded with a sealing pipe for connection 6, the left and right sides of the sealing pipe for connection 6 are bonded with sealing plates 9, the sealing plates 9 are clamped at the top of the thermoplastic pipe for internal disassembly 5, the outer ring of the sealing pipe for connection 6 is integrally formed with four heat conduction pipes 7, the outer ring of the heat conduction pipes 7 is provided with an outer sealing plate 8, in the installation process, the first thermoplastic pipe 1 and the second thermoplastic pipe 2 are fixed on the sealing plate 9 through hot air shrinkage, and through the elasticity of the thermoplastic pipe for internal disassembly 5, the problem that the sealing plate 9 is connected with the sealing pipe 6 and directly broken due to overlarge stress is avoided, the thermoplastic pipe for internal disassembly 5 is separated from the sealing plate 9 after being shrunk, thereby being convenient for external stress application, separating the sealing plate 9 from the sealing pipe for connection 6 and separating the thermoplastic pipes on both sides, and the device at the connecting part is cut off by cutting.

Evenly set up through-hole 10 on the sealed tube 6 for the connection, and through-hole 10 is located the inner chamber of heat pipe 7, just heat pipe 7 passes through-hole 10 and closing plate 9 intercommunication, with steam direct connection toward interior dismantlement with on the thermoplastic tube 5, make its quick shrink to do not influence outside thermoplastic tube normal shape.

Wherein, the sealing tube 6 for connection and the sealing plate 9 are respectively a sealing tube for connection of a heat insulation plate and a sealing plate of a heat insulation plate, which avoid the situation that the heat shrinkable tube at the outer side is shrunk again by accident to influence the secondary connection for use, the sealing plate 9 is adhered on the side wall of the sealing tube 6 for connection, so that the sealing plate 9 can be fractured by external force conveniently, a clamping groove matched with the sealing plate 9 is formed at the top of the thermoplastic tube 5 for internal disassembly in an integrated manner, the sealing plate 9 is clamped in the inner cavity of the clamping groove, a friction groove is formed at the bottom of the sealing plate 9, friction protrusions are uniformly formed on the outer wall of the thermoplastic tube 5 for internal disassembly, the thermoplastic tube 5 for internal disassembly is clamped with the sealing plate 9 through the friction protrusions, the contact area between the thermoplastic tube 5 for internal disassembly and the sealing plate 9 is increased, thereby the buffer protection effect is, set up in outer seal plate 8's the inner circle with heat pipe 7 assorted fixed slot, just outer seal plate 8 passes through the fixed slot joint on heat pipe 7, just the outer lane of heat pipe 7 is equipped with the viscose layer with outer seal plate 8 junction, realizes that outer seal plate 8 is not connected with heat pipe 7's top, after dismantling outer seal plate 8, can not appear heat pipe 7 top and be blockked up the problem emergence that leads to the unable perfusion of steam.

The working principle is as follows: when the utility model is used, the first thermoplastic pipe 1 and the second thermoplastic pipe 2 are heated and shrunk on the sealing plate 9 by taking the thermoplastic pipe 5 as a buffer through the internal disassembly and taking the sealing plate 9 as an interface position, thereby completing the connection and fixation of the two sides, improving the stress of the sealing plate 9 by taking the thermoplastic pipe 5 as an inner liner through elastic inner disassembly, reducing the sealing plate 9 fracture caused by accident, at the time of removal, the outer sealing plate 8 is removed, hot air is blown in through the heat conductive pipes 7 and the through holes 10, so that the thermoplastic pipe 5 for internal disassembly is heated and separated from the sealing plate 9, thereby reducing the magnitude of the external force resistance of the sealing plate 9, the sealing plate 9 is torn off by pulling manually to be directly connected with the sealing tube 6 for connection, and the device at the position is taken out after being cut off by foreign matters such as scissors, so that the damaged position is dismounted. The good thermoplasticity pipe of both sides is pulled again and is drawn close, cut one section pyrocondensation position back, it fixes on remaining good interior dismantlement with thermoplasticity pipe 5 to be heated the shrink (three-section thermoplasticity pipe in the middle of have two interior dismantlements to connect with thermoplasticity pipe 5, get rid of impaired position and interior dismantlement with thermoplasticity pipe 5 after, the remainder can carry out the reconnection), and connect the extension to exposed position, convenient to use, the big and with high costs problem of intensity of labour who has avoided the whole section to change.
