Abstract
The utility model relates to a metal protective pipe and particularly relates to a metal protective pipe with outer and inner coated plastics. The metal protective pipe comprises a pipe body, wherein pipe buckles are buckled mutually in a spiral mode to form the pipe body, two ends of each of the pipe buckles are respectively bent buckles, bent buckles are buckled to one another, and the outer wall of the pipe body and the inner wall of the pipe body are respectively coated with an outer flame retardant plastic protective layer and an inner flame retardant plastic protective layer. The metal protective pipe is simple in structure, high in insulation performance and pressure resistance and water proof.
Description
Technical field
The utility model is a kind of metallic protection tube, particularly a kind of inside and outside plastic metallic protection tube.
Background technology
Metallic protection tube of the prior art is used to protect cable, and general protection tube is an integral type all, though have certain flexible ability; But crushing resistance is strong, and damages easily, simultaneously between cable in the protection tube and the cable as rub; Damage easily cable, protection tube does not have water proofing property simultaneously, is embedded in when underground; The water capacity is prone to enter 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 deficiency that exists in the prior art, provide a kind of inside and outside plastic metallic protection tube.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
Plastic metallic protection tube inside and outside a kind of; Comprise body, described body is buckled mutually by the mutual spiral of pipe thread and is formed, and the two ends of pipe thread are respectively curved buttons; Curved button and the mutual snapping of curved button, described tube wall and inwall are coated with flame retardant plastics external protection and flame retardant plastics inner protective layer respectively.
As preferably, described pipe thread is " S " shape, and described body is a galvanized part.
As preferably, the thickness of described flame retardant plastics inner protective layer and flame retardant plastics external protection is 0.23mm～1mm.
Therefore, the utility model provides a kind of inside and outside plastic metallic protection tube, simple in structure, insulating properties is high, crushing resistance is strong, has certain water proofing property.
Description of drawings
Fig. 1 is the structural representation of the utility model.
