Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe supports, in particular to a steel pipe rod cross arm support. Background Art

[0002] Steel pipe pole cross arm supports play an important role in the fields of construction and engineering. The basic function of steel pipe pole cross arm supports is to provide a stable support and fixed base for the cross arm. It is generally set on iron towers, cables, and air ducts. The steel pipe pole cross arm supports can stably connect the cross arm to the steel pipe. The existing steel pipe pole cross arm supports generally have multiple fixing holes, and the cross arm and the steel pipe pole cross arm supports are generally connected by threads. Due to the changeable outdoor weather, the connection of the existing steel pipe pole cross arm supports is prone to rust and loosening. The existing steel pipe pole cross arm supports use surface galvanizing to resist oxidation and corrosion, but this connection method is still relatively easy to loosen when bearing a large weight, and the stability is poor after fixing. The loosened cross arm is easy to fall off from the steel pipe pole cross arm support. Utility Model Content
