What is the corresponding relationship between lean pipe fittings and fasteners?

Lean pipe joints and fasteners are two core components that complement each other in a flexible production line system. They work together to achieve flexible connections and structural fixation between lean pipes (wire rods). Simply put, joints are responsible for constructing the connection method and structural form, while fasteners ensure the stability and reliability of the connection.

Lean pipe joints are structural components used to connect two or more lean pipes, determining the geometric shape and assembly method of the frame. According to their functions and usage scenarios, common types include:

Right angle joint (such as HJ-1): used for vertically connecting two lean pipes, commonly used for connecting workbench corners or shelf columns to crossbeams.
Three way connector (such as HJ-2): realizes the 90 ° intersection of three lean pipes in three-dimensional space, suitable for shelf support nodes.
Four way connector (such as HJ-3): connects four lean pipes, suitable for building core nodes of complex frameworks.
Parallel joint (such as HJ-8): used for connecting two parallel pipes, supporting unilateral free turning, suitable for flexible structures such as rotating workbenches.
Angle connector (such as 45 ° external connector): realizes non right angle connection to meet special angle requirements.
Active joint (such as rotary joint): It can perform fan-shaped or circular motion and needs to be used with lubricating grease, suitable for active joint scenarios.

These joints are usually made of metal (such as cold-rolled steel plates) or die cast aluminum, and the surface is treated with electrophoresis, galvanizing, or chrome plating to enhance rust prevention and wear resistance.
