The locking device includes tooth band and head tooth cavity, and the surface of the tooth band is equipped with slip teeth, is equipped with and slides in the head tooth cavity
The groove that tooth matches.
The principle of the present invention is：Before heating, tenses locking device and heat-shrinkable T bush is made to be close to optical fiber, after heating, tempreature bulb
Fusing, tightly wraps the fibre-optical splice after welding, has the function that filling and sealing；Tempreature bulb coordinates more with heat-shrinkable T bush
Closely, tempreature bulb is not easy to fall off during optical fiber is interspersed；Asbestos stratum reticulare makes heat-shrinkable T bush be heated evenly to avoid causing part
Cross cause thermal damage optical fiber.
The present invention has the advantage that and advantageous effect：
1, the present invention is with protective effect and the FTTH optical fiber heat-shrink tubes that are heated evenly, at the outer surface port of heat-shrinkable T bush
Equipped with locking device so that the port of heat-shrink tube is closed closely after heating, has the function that filling and sealing.
2, the present invention is radially equipped with around tempreature bulb with protective effect and the FTTH optical fiber heat-shrink tubes that are heated evenly
Lug boss, the lug boss are uniformly distributed and are that integration is arranged with tempreature bulb, and heat-shrinkable T bush is equipped with and tempreature bulb matches
Groove makes tempreature bulb and heat-shrinkable T bush close fit, and overcoming the frictional force generated during optical fiber interts keeps tempreature bulb de-
From original position, installation effectiveness is improved.
3, the outer surface of the FTTH optical fiber heat-shrink tubes that the present invention carries protective effect and is heated evenly, heat-shrinkable T bush is socketed stone
Cotton net layer, when heating, make heat-shrinkable T bush be heated evenly, and avoid hot-spot, play the role of protecting optical fiber.
