Specific embodiment
As shown in figure 1, the compound material insulation pull bar of the present embodiment, including upper metal joint 1 and lower metal joint 4, with
And between upper metal joint 1 and lower metal joint 4 and for connecting the composite wood of upper metal joint 1 and lower metal joint 4
Material insulation mandrel 3, the two ends of the compound material insulation plug 3 are provided with external screw thread, the lower end of upper metal joint 1 and lower gold
The upper end of category joint 4 is provided with the female thread being engaged with the external screw thread, is gap between the external screw thread and female thread
Coordinate, in thread pitch, epoxide-resin glue 2 is filled with the Gewindefreistiche of female thread.
In the present embodiment, epoxy glue layer 5 between the external screw thread and female thread, is provided with.
In the present embodiment, the compound material insulation plug 3 is glass fiber reinforced epoxy resin insulation mandrel.
The physical dimension of upper metal joint 1 of the present utility model and lower metal joint 4 is according to the part being matched therewith
Fixed, both can be with identical, it is also possible to different, the blank material of upper metal joint 1 and lower metal joint 4 is according to the environmental requirement for using
And the size of stress can adopt aluminium alloy, stainless steel and other metal materials.
Compound material insulation pull bar of the present utility model is before assembly first by upper metal joint 1 and lower metal joint 4
The external threaded surface of thread surface and compound material insulation plug 3 is processed so that both there is good cementability
Energy；Then equal filling epoxy resin glue in the thread pitch and in the Gewindefreistiche of female thread, and in interior threaded surface and outer
Thread surface applies one layer of epoxide-resin glue；Again upper metal joint 1 and lower metal joint 4 are carried out with compound material insulation plug 3
Assembling, and adjust the relative position of metal joint 1 and lower metal joint 4, it is ensured that the fitted position of product, will finally assemble
Product fix and be heating and curing.Mechanical processing technique is simple, and machine dosage significantly reduces, and makes the overall manufacture of compound material insulation pull bar
Cost significantly reduces.
The above, is only preferred embodiment of the present utility model, not this utility model is imposed any restrictions, every
Any simple modification, change and the equivalent structure change that above example is made according to this utility model technical spirit, still
Belong in the protection domain of technical solutions of the utility model.
