For the problems referred to above, the invention provides the explosion-proof Glan of a kind of non-armoring tape braid metal lenticular wire, it is directly connected with casing one end, and metal coating conduit is directly accessed in one end, has simplified fitting operation, has improved the reliability and maintainability of system.
To achieve these goals, technical scheme of the present invention is as follows:
The explosion-proof Glan of non-armoring tape braid metal lenticular wire, is characterized in that, comprises in order to the Glan outlet joint of connect box, in order to lock the displacement-type sealing ring, intermediate transit head of lenticular wire, end of incoming cables joint in order to connection metal armour tubing;
Described end of incoming cables joint is with an endoporus, and one end of end of incoming cables joint is provided with external screw thread;
Described intermediate transit head is provided with the external screw thread being connected with Glan outlet joint, the internal thread being connected with end of incoming cables joint;
Described Glan outlet joint one end is provided with casing connecting thread, and the other end of described Glan outlet joint is provided with to connect the internal thread of intermediate transit head; Described displacement-type sealing ring comprises one section of conical section that plays the effect of locking lenticular wire, in described Glan outlet joint, be provided with the chamfering section suitable with the conical section of displacement-type sealing ring, displacement-type sealing ring is arranged on Glan outlet joint inside, be connected with intermediate transit head thread by Glan outlet joint, make the chamfering section of Glan outlet joint inwardly oppress the conical section of displacement-type sealing ring, thus locking lenticular wire.
In the present invention, the outer end of described displacement-type sealing ring is provided with pad.
In the present invention, the inwall of described intermediate transit head is provided with circlip groove, is provided with positioning retainer ring in circlip groove.
By adopting the present invention, directly one end is connected with casing, and metal coating conduit is directly accessed in one end, has simplified fitting operation, has improved the reliability and maintainability of system.
Feature of the present invention can be consulted the detailed description of the graphic and following better execution mode of this case and be obtained and be well understood to.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
In figure, 1, Glan outlet joint; 2, displacement-type sealing ring; 3, pad; 4, intermediate transit head; 5, positioning retainer ring; 6, end of incoming cables joint; 7, lenticular wire.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, further set forth the present invention below in conjunction with specific embodiment.
Referring to Fig. 1, the explosion-proof Glan of non-armoring tape braid metal lenticular wire, comprises in order to the Glan outlet joint 1 of connect box, in order to lock the displacement-type sealing ring 2, intermediate transit 4 of lenticular wire, end of incoming cables joint 6 in order to connection metal armour tubing.
End of incoming cables joint 6 is with an endoporus, and one end of end of incoming cables joint is provided with external screw thread.
Intermediate transit 4 is provided with the external screw thread being connected with Glan outlet joint, the internal thread being connected with end of incoming cables joint.The inwall of intermediate transit head is provided with circlip groove, is provided with positioning retainer ring 5 in circlip groove.
Glan outlet joint 1 one end is provided with casing connecting thread, and the other end of Glan outlet joint is provided with to connect the internal thread of intermediate transit head.Displacement-type sealing ring 2 comprises one section of conical section that plays the effect of locking lenticular wire, in Glan outlet joint, be provided with the chamfering section suitable with the conical section of displacement-type sealing ring, displacement-type sealing ring is arranged on behind Glan outlet joint inside, and the outer end of displacement-type sealing ring is provided with pad 3.Be connected with intermediate transit head thread by Glan outlet joint, make the chamfering section of Glan outlet joint inwardly oppress the conical section of displacement-type sealing ring, thus locking lenticular wire.
