Description

Technical Field

[0001] This utility model relates to the field of quick assembly and disassembly technology of push rods, and in particular to a push rod structure with a quick connector. Background Technology

[0002] A push rod is a thin-walled tube that is driven into an object, such as a tubular steel column that will later be filled with concrete, a temporary internal support, a rod used to push out a formed workpiece, a pin that goes through the back of a metal cavity to push out a finished part, a thin steel rod in the breech of an early rifle, and a projectile that is pushed into the steel rod by a push rod and tightened with the rifling.

[0003] The top rod consists of a top rod body and a top rod tail seat. When in use, the top rod is a steel pipe spliced ​​on the top of the formwork support. Its main function is to support the upper formwork and steel mesh, and at the same time stabilize the overall structure of the formwork support so that it can withstand the pressure of concrete pouring, thereby ensuring the quality and safety of construction.
