Description

Technical Field

[0001] The utility model relates to the technical field of hose connectors, in particular to a crimping type hose connector. Background Art

[0002] Wire wound hose is generally divided into wire braided hydraulic hose and wire wound hydraulic hose. Hydraulic hose is mainly composed of liquid-resistant inner rubber layer, middle rubber layer, 2 or 4 or 6 layers of wire winding reinforcement layer and outer rubber layer. The inner rubber layer has the function of making the conveying medium bear pressure and protecting the steel wire from erosion. The outer rubber layer protects the steel wire from damage. The steel wire layer is a skeleton material that plays a reinforcing role. The pipe joint is a connection tool between pipelines and is a detachable connection point between components and pipelines. It plays an indispensable and important role in pipe fittings. There are many types of pipe joints. Commonly used pipe joints can generally be divided into two types: hard pipe joints and hose joints. In the oil pipeline of engineering machinery and equipment such as excavators, rollers, loaders or forklifts or oil pumps, hose joints are generally used, especially high-pressure hose joints to connect the hose with engineering machinery and equipment or oil pumps. One end of the hose joint is connected to the hose, and the other end is connected to the plug-in of the oil delivery hose of the engineering machinery and equipment or oil pump.

[0003] The existing hydraulic hose connector is usually connected to the hose in the form of a threaded connection, but the threaded connection is very likely to cause the hose connector to become loose. Once the hose connector becomes loose, it will cause oil and water leakage. Therefore, a crimping type hydraulic hose connector is needed. Utility Model Content
