Abstract
The utility model is a kind of metal hose, all covers the metal hose of PVC protective layer inside and outside particularly a kind of.Comprise the body being formed by the mutual spiral snapping of pipe thread; the inwall of described body is provided with interior PVC protective layer; the outer wall of described body is provided with outer PVC protective layer; in described body, be provided with the location ring support fixing with interior PVC protective layer, the inwall of described location ring support is provided with equally distributed spring contact.Inside and outside all cover PVC protective layer metal hose improve electric wire useful life, improve fail safe.
Description
Technical field
The utility model is a kind of metal hose, all covers the metal hose of PVC protective layer inside and outside particularly a kind of.
Background technology
Metal protecting tube of the prior art is for the protection of cable; general protection tube is all integral type, although have certain flexible ability, crushing resistance is strong; and easily damage; between cable in while protection tube and cable, as rubbed, easily damage cable, protection tube does not have water proofing property simultaneously; be embedded in when underground; the water capacity easily enters into protection tube, makes cable water inlet, has reduced fail safe.
Summary of the invention
Utility model is mainly to solve the deficiencies in the prior art, and a kind of compact conformation is provided, and effectively protects electric wire, increases the service life, and electric wire is carried out all covering inside and outside lock-bit a kind of the metal hose of PVC protective layer simultaneously.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Inside and outside a kind of, all cover the metal hose of PVC protective layer; comprise the body being formed by the mutual spiral snapping of pipe thread; the inwall of described body is provided with interior PVC protective layer; the outer wall of described body is provided with outer PVC protective layer; in described body, be provided with the location ring support fixing with interior PVC protective layer, the inwall of described location ring support is provided with equally distributed spring contact.
As preferably, the thickness of described interior PVC protective layer is 0.23-1mm, and the thickness of described outer PVC protective layer is 0.4-1mm.
As preferably, the material of described body is galvanized part.
Interior PVC protective layer and outer PVC are protective layer used injury-free in protection body; Soft touching between spring contact and electric wire makes electric wire not encounter inboard wall of tube body simultaneously, promoted fail safe on the one hand, also extended useful life on the other hand.Spring contact can be that plastics software can be also metallic elastic part.
Therefore, the utility model provides all covers the metal hose of PVC protective layer inside and outside a kind of, improves electric wire useful life, improves fail safe.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
