Description
Technical Field
[0001] The utility model relates to the field of connecting fasteners, in particular to a single-ear stepless clamp. Background Art
[0002] The single-ear clamp is also called a single-ear stepless clamp. The term "stepless" means that there is no protrusion or gap on the inner ring of the clamp. The 360° stepless design achieves uniform force compression on the surface of the pipe fitting and 360° sealing guarantee. The single-ear stepless clamp is used to connect and fix the hose and the hard pipe in the gas or liquid transmission circuit, and the single-ear stepless clamp is used to tighten the joint. For example, in the connection of soft and hard pipes on pipeline transportation equipment such as automobiles, trains, ships, water supply systems, beer machines, coffee machines, beverage machines, medical equipment, petrochemicals, etc., the above-mentioned single-ear stepless clamp is used in a non-detachable use environment. In the prior art, the hoop is locked with a buckle, which is difficult to tighten for pipes of different sizes.
