All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like, indicate orientations and positional relationships based on those shown in the drawings, and are used only for convenience of description and simplicity of description, and do not indicate or imply that the equipment or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be considered as limiting the present invention.

In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

Referring to fig. 1-3, the present invention provides a technical solution:

the utility model provides a PPR water supply pipe, including inoxidizing coating 1 that sets gradually from the extroversion, PPR middle level 2 and PPR inlayer 3, be equipped with reinforcing mechanism 4 in the PPR middle level 2, reinforcing mechanism 4 includes a plurality of copper pipes 40 that are the annular array and arrange, improve the whole crushing resistance of water supply pipe, all be equipped with arc copper sheet 41 between every two adjacent copper pipes 40, make a plurality of copper pipes 40 connect into whole, do not adopt the copper ring structure, because the crushing resistance of copper ring structure is relatively poor, can not disperse stress, be equipped with regular triangle support 5 in the PPR inlayer 3, when laying the water supply pipe, can regard when building decoration probably place the place of heavier article subaerial, when the position of water supply pipe can not change again if the underground of this department need be laid, can be with the water supply pipe internally mounted regular triangle support 5 of this position department, thereby avoid the water supply pipe to be crushed.

In this embodiment, the copper tube 40 is provided with the cross-shaped bracket 42 therein, so that the copper tube 40 has good compression resistance and bending resistance.

Specifically, the external diameter of copper pipe 40 is the same with the thickness of PPR middle level 2, and the outer wall of copper pipe 40 offsets with the inner wall of inoxidizing coating 1 and the outer wall of PPR inlayer 3 respectively, plays the effect of support and resistance to compression to transmit the atress to PPR inlayer 3, thereby improve the whole crushing resistance of feed pipe.

Furthermore, the protective layer 1 is made of HDPE resin material, and the HDPE resin material has good mechanical property and has the advantages of impact resistance, cracking resistance, aging resistance, corrosion resistance and the like.

Furthermore, the thickness of the protective layer 1 is the same as that of the PPR inner layer 3, so that the outer layer of the water supply pipe has good impact resistance, cracking resistance and aging resistance, the thickness of the PPR middle layer 2 is larger than that of the PPR inner layer 3, and the PPR middle layer 2 is used for arranging a reinforcing mechanism 4, so that the pressure resistance of the water supply pipe is further improved on the basis of the protective layer 1.

Further, three edges of regular triangle support 5 all are equipped with connecting filler strip 50, and one side that connecting filler strip 50 kept away from regular triangle support 5 offsets with the inner wall of PPR inlayer 3, makes regular triangle support 5 can be fixed a position in PPR inlayer 3, avoids being driven by rivers.

When the PPR water supply pipe is used, a constructor can determine the position above the water supply pipe to place a heavy object after decoration according to decoration drawings when laying a water supply pipe network, when the position of the water supply pipe is not easy to change, constructors can put the regular triangle support 5 with the adaptive length into the water supply pipe at the position, after the regular triangle support 5 is put into the PPR inner layer 3, because the three connecting filler strips 50 are abutted against the inner wall of the PPR inner layer 3, the position of the regular triangle bracket 5 is fixed, the regular triangle bracket 5 is prevented from shifting in the water supply pipe, under the effect of regular triangle support 5 and reinforcing mechanism 4, can effectively improve the crushing resistance of this feed pipe, avoid the building because placed the heavy object after the fitment, lead to the feed pipe to take place the condition of crushing after long-time the use to prevent the condition that the building seeped water and unable normal water supply from appearing.

The foregoing shows and describes the general principles, essential features, and advantages of the utility model.
