Description

Technical Field

[0001] The utility model relates to the technical field of PP pipes, in particular to a composite PP pipe structure with weather resistance. Background Art

[0002] PP pipes are non-toxic, hygienic, high-temperature resistant and recyclable. They are mainly used in indoor hot and cold water supply systems in buildings and are also widely used in heating systems. In order to adapt to modern process requirements, flame retardant materials and high-temperature resistant materials are generally added to the materials used to make PP pipes, so that the produced pipes have certain flame retardancy and high-temperature resistance. However, when existing PP pipes are used for a long time, since there is no protective mechanism on their surface, once the surface collides with external sharp objects, it will cause damage to the surface of the PP pipe. After long-term use, leakage will occur, causing economic losses. Therefore, a composite PP pipe structure with weather resistance is proposed to address the above problems. Utility Model Content

[0003] The purpose of the present invention is to provide a composite PP pipe structure with weather resistance function to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a composite PP tube structure with weather resistance function, comprising an antibacterial inner tube, a PP tube and a limiting protrusion;

[0005] The outer side of the antibacterial inner tube is fixedly connected to a PP tube, the outer side of the PP tube is fixedly connected to evenly distributed limiting bumps, and the outer side of the limiting bumps is installed with a protective component;

[0006] The protective assembly includes a protective sleeve, a groove and a first connecting hole. The protective sleeve is provided with a groove inside, and the protective sleeve is engaged with the limiting protrusion through the groove. The protective sleeve is provided with evenly distributed first connecting holes and second connecting holes on both sides.

[0007] The interior of the protective sleeve is fixedly connected with uniformly distributed reinforcement rods;

[0008] A fixing bolt is provided inside the second connecting hole, and the other end of the fixing bolt is spirally connected to the protective sleeve through the first connecting hole.

[0009] Furthermore, washers are provided on the outer sides of the fixing bolts.

[0010] When the existing PP pipe is used for a long time, since there is no protective mechanism on its surface, once the surface collides with external sharp objects, the surface of the PP pipe will be damaged. Leakage will occur over a long period of time, causing economic losses. When in use, the protective component is put on the outside of the limiting protrusion, and the reinforcing rod is penetrated by a fixing bolt and then connected to the first connecting hole of the protective sleeve on the other side. At this time, the protective sleeves on both sides are connected. At this time, it can be ensured that the protective sleeve is covered on the outside of the PP pipe, which plays the purpose of protecting the PP pipe and preventing it from being punctured by some external sharp objects.

[0011] Furthermore, a reinforcement mesh cover is fixedly connected to the interior of the protective sleeve, and the reinforcement mesh cover is arranged in an arc shape.

[0012] Furthermore, the reinforcement mesh cover is made of stainless steel wire.

[0013] The inside of the protective sleeve is provided with a reinforcement rod and a reinforcement mesh cover, which can reinforce the protective sleeve. The provided groove cooperates with the limiting protrusion to ensure that the protective sleeve stably covers the outside of the PP pipe to prevent them from rotating relative to each other.

[0014] Furthermore, a heat-insulating layer is fixedly connected to the inner side of the protective sleeve, and the heat-insulating layer is made of glass fiber.

[0015] Furthermore, the number of the protective sleeves is two groups, and the protective sleeves are arranged in a semicircular ring shape.

[0016] The inside of the protective sleeve is also provided with an insulation layer, which is in close contact with the outer surface of the PP pipe. At this time, it can play a certain insulation purpose and prevent the external high temperature from damaging the PP pipe.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] When the utility model is in use, the protective assembly is sleeved on the outside of the limiting protrusion, and the fixing bolt passes through the reinforcement rod and is then connected to the first connecting hole of the protective sleeve on the other side. At this time, the protective sleeves on both sides are connected. At this time, it can be ensured that the protective sleeve covers the outside of the PP pipe, thereby protecting the PP pipe and preventing it from being punctured by some external sharp objects.

[0019] The inside of the protective sleeve is provided with a reinforcement rod and a reinforcement mesh cover, which can reinforce the protective sleeve, and the provided groove cooperates with the limiting protrusion to ensure that the protective sleeve stably covers the outside of the PP tube to prevent them from rotating with each other;

[0020] The inside of the protective sleeve is also provided with an insulation layer, which is in close contact with the outer surface of the PP pipe. At this time, it can play a certain insulation purpose and prevent the external high temperature from damaging the PP pipe. BRIEF DESCRIPTION OF THE DRAWINGS
