Description

Technical Field

[0001] The utility model relates to the technical field of hoses, in particular to a tractor chassis high-pressure hose. Background Art

[0002] Tractors are favored by farmers for their simple structure, easy operation, light weight, flexibility, high efficiency, wide application and low price. Hoses are usually installed on the chassis of tractors to transmit gas. Hoses are important components in modern industry. Hoses are mainly used as wire and cable protection tubes for wires, cables, and automation instrument signals, and civilian shower hoses. Small-diameter hoses are mainly used for sensor line protection of precision optical rulers and industrial sensor line protection. According to their uses, they are mainly divided into threading hoses, drainage hoses, ventilation hoses, shower hoses and wiring harness hoses. According to their materials, they are mainly divided into stainless steel hoses, metal hoses, corrugated hoses, rubber hoses and plastic hoses.

[0003] According to the application number: CN201110272337.4, a heat-insulating hose includes a hose inner layer and a hose outer layer, a certain space gap is provided between the hose inner layer and the outer layer to form an annular space, and the hose inner layer and the outer layer are connected by an elastic column. The characteristics of this new use are that, since there is a certain space gap between the inner and outer hoses, the fluid can dissipate part of the heat through the annular space when flowing in the inner hose, and since there is an elastic column between the inner and outer layers, when the hose is bent, due to the elastic force, the relative position of the inner and outer layers will not change, and on the other hand, the elastic column can stabilize the gap distance between the inner and outer hoses, thereby extending the service life of the hose.

[0004] The hose in the above case has low strength and toughness, and poor pressure resistance, which seriously affects the pressure the hose can withstand during use, reducing the service life and applicability of the hose. For this reason, we provide a tractor chassis high-pressure hose. Utility Model Content
