Abstract
The utility model discloses a threading pipe, which comprises a hollow threading pipe body (1) made of plastics. The threading pipe is characterized in that at least one annular metal layer (2) concentric with the threading pipe body (1) is arranged between the inner wall and the outer wall of the threading pipe body (1). The threading pipe is fine in insulation effect, light in weight, low in cost, fine in strength and fine in shielding effect.
Description
Technical field
The utility model relates to tubing, specifically is a kind of penetration pipe.
Background technology
Present penetration pipe generally comprises plastics penetration pipe and metal penetration pipe, what the plastics penetration pipe was maximum is to adopt PVC to make, also have and adopt RPE to make, the penetration pipe that this plastics are made have the good insulation effect, in light weight, cost is low, but its intensity is low, shield effectiveness is poor; And the metal penetration pipe has preferably intensity, shield effectiveness good, but insulation effect is poor, Heavy Weight, cost height.Current urgent need is a kind of to have the penetration pipe that insulation effect is good, in light weight, cost is low, intensity good, shield effectiveness is good simultaneously.
The utility model content
The technical problems to be solved in the utility model is that the penetration pipe that a kind of insulation effect is good, in light weight, cost is low, intensity good, shield effectiveness is good is provided.
The technical solution of the utility model is, a kind of penetration pipe with following structure is provided, and comprises the hollow penetration pipe body that is made of plastics, and also is provided with one deck and the concentrically ringed annular metal layer of penetration pipe body at least between the inside and outside wall of described penetration pipe body.
After adopting above structure, the utility model compared with prior art has the following advantages: because described penetration pipe body is made of plastics, so insulation effect, in light weight, cost is low; Again owing to also be provided with one deck and the concentrically ringed annular metal layer of penetration pipe body at least between the inside and outside wall of described penetration pipe body, make penetration pipe have preferably intensity, shield effectiveness good.
As improvement, described metal level is two-layer, makes the intensity of penetration pipe of the present utility model and shielding properties better.
Description of drawings
As shown in the figure: 1, penetration pipe body, 2, metal level.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, penetration pipe of the present utility model, comprise the hollow penetration pipe body 1 that is made of plastics, also be provided with one deck and penetration pipe body 1 concentrically ringed annular metal layer 2 at least between the inside and outside wall of described penetration pipe body 1, metal tube just, this metal level 2 can add at penetration pipe and is injection-moulded in inside man-hour, makes metal level 2 be fixed on the inside of penetration pipe body 1.
As shown in Figure 2, described metal level 2 is two-layer, is plastic layer between this two metal layers 2, also is plastic layer between the inwall of inboard metal level 2 and penetration pipe body 1, also is plastic layer between the outer wall of outer metal layers 2 and penetration pipe body 1.
The metal level 2 of penetration pipe of the present utility model can select iron, copper, aluminium or the like metal to make.
Claims (2)
1. a penetration pipe comprises the hollow penetration pipe body (1) that is made of plastics, and it is characterized in that: also be provided with one deck and the concentrically ringed annular metal layer of penetration pipe body (1) (2) at least between the inside and outside wall of described penetration pipe body (1).
2. penetration pipe according to claim 1 is characterized in that: described metal level (2) is for two-layer.
