Metal hose

Abstract

The invention discloses a metal hose. A hose body is provided with an inner pipe, a corrugated pipe and a metal net. The inner pipe is arranged inside the corrugated pipe. The metal net is arranged outside the corrugated pipe. The inner pipe is formed by sequentially lapping a plurality of manganese steel circular ring steel pipes. A heat resisting material is arranged between the corrugated pipe and the inner pipe. Connectors at the two ends of the metal pipe are in threaded connection. The connector with an inner thread and the connector with an outer thread are arranged at the two ends of the metal pipe respectively. Due to the fact that the metal net is located on the outermost layer of the hose, the abrasion resistance of the metal hose can become better during using. Meanwhile, the heat resisting material is arranged between the corrugated pipe and the inner pipe, so that the temperature distortion of the metal hose is not liable to happen due to the heat resisting material, using is facilitated, and the metal hose is safer.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a metal hose. Background technique [0002] The metal hose is rotatable like a plastic pipe and has the hardness like an ordinary metal pipe, and the metal hose is easy to install and can ensure the relative movement requirements between the connecting parts. In many cases, we will use metal hoses. The installation environment of hoses, subways, urban underground, urban buildings and other cables is particularly harsh. Over time, the cables are prone to aging, oxidation, etc., causing damage to the cables. In the existing technology, flat-coated plastic metal hoses Generally, it includes (P3 type) metal hose and outer plastic coating. In the application process of modern society, circuit aging or other causes of fire will cause property loss on the one hand, and on the other hand, because the flat plastic metal hose is made of PPC material. The fire performance of the outer plastic coatin...

[0002] The metal hose is rotatable like a plastic pipe and has the hardness like an ordinary metal pipe, and the metal hose is easy to install and can ensure the relative movement requirements between the connecting parts. In many cases, we will use metal hoses. The installation environment of hoses, subways, urban underground, urban buildings and other cables is particularly harsh. Over time, the cables are prone to aging, oxidation, etc., causing damage to the cables. In the existing technology, flat-coated plastic metal hoses Generally, it includes (P3 type) metal hose and outer plastic coating. In the application process of modern society, circuit aging or other causes of fire will cause property loss on the one hand, and on the other hand, because the flat plastic metal hose is made of PPC material. The fire performance of the outer plastic coating is extremely poor, and at the same time, it is easy to generate a large amount of toxic gas when burning, which causes a lot of hidden dangers to people's life safety, and the metal hose in the existing technology does not have a good airtight method at the joint
