Description

Technical Field

[0001] The utility model relates to the technical field of pipeline manufacturing, and more specifically, to a plastic-coated hose. Background Art

[0002] The plastic-coated metal hose has many excellent properties, but the only disadvantage is that the plastic coating will age, and the aged plastic layer is easy to break and fall off when being bent at a large angle, and cannot play the original protective role, and the overall effect is not good. Based on this, the utility model proposes a plastic-coated hose. Utility Model Content

[0003] The utility model aims to overcome the above-mentioned deficiencies in the prior art and to provide a plastic-coated hose, which has the characteristics of long plastic layer service life and good protection effect.

[0004] In order to solve the above technical problems, the purpose of the utility model is achieved as follows: the utility model involves a plastic-coated hose, including a hose body, the hose body is composed of a double-buckle metal hose and a soft rubber layer plastic-coated on the outside, and also includes a compression spring, the inner side or outer side of the compression spring is provided with a plurality of pipeline fixing clamps arranged at intervals along its extension trajectory, the hose body is bent into a spiral shape, and the hose body is clamped on all pipeline fixing clamps in sequence.

[0005] The utility model is further configured as follows: the pipeline fixing clamp is in a U-shape, and the pipeline fixing clamp has a constricted portion close to the clamping opening.

[0006] The utility model is further configured as follows: the pipeline fixing clamp has a flaring portion arranged at the clamping opening.

[0007] The utility model is further configured such that the spacing between two adjacent pipeline fixing clamps is equal.

[0008] The utility model is further configured as follows: the compression spring and the pipeline fixing clamp are both made of stainless steel, and the pipeline fixing clamp is welded to the compression spring.

[0009] In summary, the utility model has the following beneficial effects: the plastic-coated hose involved in the utility model arranges a compression spring to guide the hose to extend, and the compression spring then acts as an elastic bracket to limit the bending of the hose and restrict its deformation at a larger bending angle, thereby protecting the aged plastic layer, extending its service life, enhancing the protective effect, and having complete overall functions and strong practicality.
