In some special applications, the connection device of the hydraulic oil pipe must have an insulating function. For example, the flash welding machine for welding anchor chains adopts two high-power dry-type transformers and rectifying devices, converts input 380V alternating current into direct current of 12V and more than 10000A, and outputs the direct current to two pairs of electrode blocks which respectively clamp the ports of chain ring bodies to be welded. The electrode block presses and clamps the end port of the chain link to be welded, and the electrode block drives the end port of the clamped chain link to move transversely and repeatedly frequently to complete flash welding. The hydraulic oil pipes of the three oil cylinders for up-and-down movement, front-and-back adjustment and up-and-down adjustment of the electrode block must be insulated from the hydraulic power source and the body of the flash welding machine, otherwise, the low-voltage large-current direct current input into the electrode block can cause the hose steel wire of the multilayer steel wire braided rubber tube and the welding joints pressed in the two ends of the hose steel wire to generate heat and instantly lose efficacy. The existing insulating oil pipe adopts a structure that a layer of insulating material is added between a multilayer steel wire woven rubber pipe and a welding joint body pressed at two ends of the multilayer steel wire woven rubber pipe, so that the insulating layer is easy to damage and lose efficacy after the welding joint body with the structure is used for a long time.
