Abstract
The utility model relates to a metal protecting tube, in particular to a metal protecting tube coated with PVC inside and outside. The tube comprises a tube body. The tube body is spirally interlocked by a tube fastener. The outer wall and the inner wall of the tube body are coated with a PVC outer protecting layer and a PVC inner protecting layer respectively . The tube has the advantages of high insulating ability, strong crushing resistance, definite water resistance and long useful life.
Description
Technical field
The utility model is a kind of metallic protection tube, all covers the metallic protection tube of PVC inside and outside particularly a kind of.
Background technology
Metallic protection tube of the prior art is used to protect cable; general protection tube is an integral type all, though have certain flexible ability, crushing resistance is strong; and damage easily; as rubbing, damage cable easily between cable in the while protection tube and the cable, protection tube does not have water proofing property simultaneously; be embedded in when underground; the water capacity easily enters into protection tube, makes the cable water inlet, has reduced fail safe.
Chinese patent CN201323430 discloses a kind of novel cable protection tube, and it comprises crooked first and second portion, and its end is suitable for connecting to form cavity.This utility model brown protection tube, only be fit to short-range use, and also need the clamping protection tube after installing cable additional; strengthened workload greatly, troublesome poeration is made up of two parts simultaneously; simultaneously anti-extrusion performance reduces, and causes reduce useful life, does not have water resistance.
Summary of the invention
Utility model mainly is to solve the deficiencies in the prior art, and the metallic protection tube that all covers PVC inside and outside a kind of is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
All cover the metallic protection tube of PVC inside and outside a kind of, comprise body, body is buckled mutually by the pipe thread spiral and is formed, and described tube wall and inwall wrap respectively to carry out PVC external protection and PVC inner protective layer.
As preferably, the applying that is complementary of described PVC inner protective layer and PVC external protection and body.
As preferably, described pipe thread is " S " shape, and the two ends of pipe thread are curved button, curved button and the mutual snapping of curved button.
As preferably, described body is a galvanized part.
As preferably, the thickness of described PVC inner protective layer and PVC external protection is 0.23mm～1mm.
Therefore, the utility model provides all covers the metallic protection tube of PVC inside and outside a kind of, the insulating properties height, and crushing resistance is strong, has certain water proofing property, increases the service life.
