Abstract:
An insulation pull bar (100) comprises an insulation pipe (101) and joints (102) fitted to the two ends of the insulation pipe (101). Each joint (102) comprises an insertion end (110) in axial fitting connection with the insulation pipe (101) and an exposing end (120) extending out from the insertion end (110). A wedge-shaped glue receiving cavity (130) is arranged between the insertion end (110) and the insulation pipe (101). A glue liquid (131) is filled into the wedge-shaped glue receiving cavity (130). According to the insulation pull bar (100), the wedge-shaped glue receiving cavity (130) is arranged between the insertion end (110) and the insulation pipe (101), the wedge-shaped glue receiving cavity structure of the insulation pull bar (100) enables the insulation pull bar (100) to spread a stress surface when being pulled, which effectively improves the stress condition of a glued connection part, and increases the tensile strength, so that safety and reliability are achieved.
