Abstract

The utility model discloses a thermal insulation rubber and plastic pipe capable of avoiding axial endplay comprises a plastic inner pipe and a rubber and plastic pipe wrapped on the outer wall of the plastic inner pipe. The outer wall of the plastic inner pipe is provided with more than two annular protrusions to be closely matched with the rubber and plastic pipe. The thermal insulation rubber and plastic pipe utilizes the structure of the annular protrusions on the outer wall of the plastic inner pipe to be closely matched with the rubber and plastic pipe, thereby effectively avoiding the problem of axial endplay and improving thermal insulation effect.

Description

Prevent the insulation rubber plastic pipe of axial float

Technical field

The utility model relates to a kind of rubber plastic pipe, relates in particular to the insulation rubber plastic pipe that prevents axial float.

Background technique

The insulation rubber plastic pipe is because thermal conductivity hangs down complete hole-closing structure, and insulation effect is good lastingly; Material and steam are isolated fully, do not absorb water, condensation not, characteristics such as long service life, its preferably the heatproof weather resisteant make it be very suitable for the insulation of solar water heater hot-water line; The car air conditioner pipe, the steam tube insulation.Have now when some car air conditioners are guaranteed temperature because vibrations, rubber plastic pipe and its plastic inner pipe are easy to generate the play phenomenon and influence heat insulation effect.

China utility model patent patent No. 201020523206.X discloses a kind of rubber plastic pipe, sheet material is continuous foamed and the moulding modular system; It is along the production line direction; One section infrared rays preheating section, plurality of sections heated air circulation bringing-up section and one section insulation cooling section are set successively continuously, and each section main body is rectangular casing, and casing is all with the shaped steel framework that is welded; The casing inner and outer surface seals with thin plate; Constitute jacket structured, thermal insulating material be full of and compacting in the chuck space, be equipped with rollgang in the casing.The rubber plastic pipe of this kind device fabrication does not propose to prevent the method for rubber plastic pipe and plastic inner pipe generation play.

Summary of the invention

The utility model provides a kind of simple in structure, easy for installation, insulation rubber plastic pipe of preventing axial float.

A kind of insulation rubber plastic pipe that prevents axial float; The rubber plastic pipe that comprises plastic inner pipe and be coated on the plastic inner pipe outer wall; The plastic inner pipe outer wall is provided with two the above annular protrusions and the rubber plastic pipe that closely cooperates; Utilize annular protrusion structure and rubber plastic pipe to closely cooperate effectively to have prevented the axial float problem of insulation rubber plastic pipe, improved heat insulation effect.

The two ends that rubber plastic pipe is all exposed at described plastic inner pipe two ends, plastic inner pipe two ends are equipped with convenient other pipe fittings that connect of positioning ring of two convexities.

The utility model prevents that the insulation rubber plastic pipe of axial float from utilizing annular protrusion structure and the rubber plastic pipe of plastic inner pipe outer wall to closely cooperate effectively to have prevented the axial float problem of insulation rubber plastic pipe, has improved heat insulation effect.

Description of drawings

Be illustrated in figure 1 as the insulation rubber plastic pipe sectional structure schematic representation that the utility model prevents axial float.

Embodiment

A kind of insulation rubber plastic pipe that prevents axial float as shown in Figure 1; The rubber plastic pipe 1 that comprises plastic inner pipe 2 and be coated on plastic inner pipe 2 outer walls; Plastic inner pipe 2 outer walls are provided with two the above annular protrusions and the rubber plastic pipe 1 that closely cooperates, and utilize annular protrusion effectively to prevent the axial transmission of rubber plastic pipe 1.

Improve the two ends that the connection agility of insulation rubber plastic pipe is all exposed rubber plastic pipe 1 at plastic inner pipe 2 two ends as structure optimization, the positioning ring 3 that plastic inner pipe 2 two ends are equipped with two convexities other pipe fittings that are connected.
