Detailed Description

The technical solutions of the present invention will be described in detail and fully hereinafter with reference to the accompanying drawings and detailed description, it being understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Example (b): this embodiment provides a depression bar frock for rolling up system pipe fitting fast leveling, include atress depression bar portion 1, locate the U type joint portion 2 of 1 one end in atress depression bar portion, be equipped with U type bayonet 3 on the U type joint portion 2. The stress rod part 1 is used as a stress structure of the pressure rod tool and bears the acting force of the pressure rod tool when the position of the pipe section is adjusted. The utility model discloses a pipe wall of the bayonet socket calliper pipeline section of U type joint portion 2, the pipeline section can be different specifications, then utilize lever principle through the position of applying external force quick adjustment pipeline section to the depression bar according to actual need. The stress pressure rod part 1 is made of Q235B steel, the specification length is 2026mm, the pipe diameter is 46mm, and the pipe wall thickness is 4 mm. U type bayonet joint portion 2 adopts specification length to be 196mm, and width 120mm, thickness 20 mm's steel sheet make, cuts a 86mm x 93 mm's panel at 87mm apart from steel sheet one end, makes it approximate to the U type board to form U type bayonet socket 3.
