Description:
Plastic handle Germany type clamp is also know as hose clamp with thumb screw. It is a metal clamping device designed for fastening hoses to pipes, featuring a handle for quick and tool-free tightening/loosening, suitable for scenarios requiring regular maintenance or repositioning.
Structural Composition:
- Clamping Band: Fabricated from corrosion-resistant stainless steel or zinc-plated steel, incorporating precision-stamped non-perforations to optimize grip performance.
- Drive Assembly: Integrates either a worm-drive or linear gear mechanism, converting rotational handle motion into precise circumferential tension control.
- Operating Lever: Available in collapsible or rigid configurations utilizing metallic or high-strength polymer materials to deliver mechanical advantage with minimal input force.
Operating Principle:
- Tightening. Rotate handle clockwise → Drives worm gear rotation → Engages band grooves → Uniformly reduces diameter
- Loosening. Rotate handle counterclockwise → Releases worm gear pressure → Spring assist expands band
Material:
Multiple material options available.
W1 - All parts carbon steel with zinc plated, handle plastic
W2 - Hosing and band stainless steel 201/301/304, screw carbon steel with plastic handle
Operating Principle:
- Tightening. Rotate handle clockwise → Drives worm gear rotation → Engages band grooves → Uniformly reduces diameter
- Loosening. Rotate handle counterclockwise → Releases worm gear pressure → Spring assist expands band
