Description of drawings
The present invention is described further below in conjunction with drawings and Examples:
Fig. 1 is the structural representation of the embodiment of the invention;
Among the figure: 1 main connector, 11 first links, 12 second links, 13 first inner chambers, 14 second inner chambers, 15 annular slots, 16 internal ring walls, 17 connect boss, 2 first connect screw, 21 cylindrical shells, 22 preceding shroudings, 23 through holes, 3 second connect screw, 31 cylindrical shells, 32 back shroudings, 33 through holes, 4 binding rings, 5 metal bellowss, 6 plastic-aluminum pipes, 61 inner coverings, 62 aluminium foil layers, 63 metal charge layers, 64 outer jackets, 7 sealing gaskets.
Embodiment
As shown in Figure 1, this downlead screen jockey comprises that mainly main connector 1, first connects screw 2, second and connects screw 3, binding ring 4.
Main connector 1 is provided with first link 11 that connects metal bellows 5, connects second link 12 of plastic-aluminum pipe 6.First link 11, second link 12 are equipped with external screw thread.First link 11 arranges first inner chamber, 13, the second links 12 second inner chamber 14 is set; First inner chamber 13, second inner chamber, 14 coaxial communication form a ladder through hole.Described second link 12 is at the peripheral coaxial annular slot 15 that is provided be used to the aluminium foil layer 61 that clamps plastic-aluminum pipe 6 of second inner chamber 14, be internal ring wall 16 between annular slot 15 and second inner chamber 14, the outer peripheral face of described internal ring wall 16 is provided with tapering, and the diameter of internal ring wall 16 outer peripheral faces is along being reduced gradually by the direction of first link 11 to second link 12.
First connects screw 2, is made up of cylindrical shell 21 and the preceding shrouding 22 that is installed in cylindrical shell 21 front ends; Cylindrical shell 21 arranges internal thread and cooperates with the external screw thread of first link 11 of described main connector, and preceding shrouding 22 is provided with the through hole 23 that passes for described metal bellows 5.
