Coupler

A coupler is a mechanical device used to securely connect two or more components(usually rods,pipes,or profiles),widely used in fields such as construction,machinery,industry,and transportation.Its core function is to combine dispersed components into a stable overall structure through clamping force,thread engagement,or mechanical locking,ensuring the reliability and safety of the connection.

1、Core Features and Classification

Couplers can be classified into various types based on their application scenarios and connection methods,with common classifications as follows:

1.Divided by connection angle

Right Angle Coupling:Used for 90°connection of vertical cross components(such as uprights and crossbars),it is the core component of building scaffolding.

Swivel Coupling:Flexible adjustment of connection angle(0°-180°),suitable for diagonal support or irregular structures.

Straight Coupling:Used for straight extension connections of coaxial components,such as steel pipe joints to increase length.

2.Divided by application field

Scaffold coupler:designed specifically for building scaffolding,connecting steel pipes to form a construction platform or support system.

Pipe Coupling:Used for connecting plumbing and industrial pipelines,it may include a sealing function to prevent leakage.

Mechanical coupler:used in mechanical transmission systems to connect shaft or rod components and transmit torque or axial force.

3.Divided by materials and processes

Cast Iron Coupler:Low cost,suitable for medium to low load scenarios,manufactured through casting processes.

Forged Steel Coupling:High strength,impact resistant,suitable for heavy loads(such as bridge construction),reinforced with forging technology to enhance material properties.

Pressed Steel Coupler:Lightweight,high production efficiency,suitable for lightweight structures or temporary facilities.
