Description

Technical Field

[0001] The utility model relates to the technical field of PVC pipeline equipment, in particular to a plastic PVC pipeline with wear-resistant function. Background Art

[0002] Plastic PVC pipes are a commonly used pipeline structure. Due to their high toughness, strong environmental adaptability and high cost-effectiveness, they have become one of the mainstream building materials for pipeline construction.

[0003] The prior art has the following deficiencies: the prior art publication number CN213776642U states that “a plastic PVC pipe with wear-resistant function” “includes a pipe body, the pipe body includes a polyvinyl chloride pipe, a moisture-proof and mildew-proof coating, a high-temperature resistant layer, a corrosion-resistant layer, a wire mesh layer and a wear-resistant layer, the outer surface of the polyvinyl chloride pipe is fixedly provided with a moisture-proof and mildew-proof coating, and the outer surface of the moisture-proof and mildew-proof coating is fixedly provided with a high-temperature resistant layer”;

[0004] The above structure greatly improves the heat resistance of the PVC pipe by setting a high-temperature resistant layer on the outer surface of the PVC pipe, so that it can be used in a high-temperature environment. However, the structure only enhances the wear resistance of the pipe by means of a wear-resistant layer and a wear-resistant strip. In essence, it is still subject to continuous wear, and the external protective structure is an integrated design, which is not convenient for the transportation and installation of the entire pipe. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a plastic PVC pipe with wear-resistant function, which solves the current problems of insufficient wear resistance and insufficient flexibility in integrated design, installation and transportation.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a plastic PVC pipe with wear-resistant function, comprising a pipe body, an outer shell, and a sliding tooth, wherein the outer shell is arranged on the outer end surface of the pipe body, and the sliding tooth is arranged on the outer end surface of the outer shell;

[0007] An outer protective frame is also provided on the periphery of the outer shell;

[0008] The outer protection frame also includes a cover plate, an isolation rubber ring, and a slide groove. The cover plate is fixedly connected to the inner end surface of the outer protection frame, the isolation rubber ring is sleeved on the outer end surface of the outer protection frame, and the slide groove is opened on the inner side of the cover plate.

[0009] As a preferred technical solution of the present utility model, the pipe body also includes a tin-plated metal layer and an epoxy resin coating. The tin-plated metal layer is covered on the inner wall surface of the pipe body by electroplating, and the epoxy resin coating is covered on the outer surface of the pipe body by external brushing.

[0010] As a preferred technical solution of the utility model, the isolation rubber ring is an annular rubber ring structure as a whole, made of plastic material, has the ability to bend and stretch at multiple angles, and is provided in five groups and equidistantly distributed according to the laying path of the pipeline body.

[0011] As a preferred technical solution of the utility model, the sliding grooves and sliding teeth are provided in four groups, and are in sliding connection with each other.

[0012] As a preferred technical solution of the utility model, the pipe body is connected to the outer shell in an active manner by plugging.

[0013] As a preferred technical solution of the utility model, the outer cover shell and the outer protection frame can be stored and transported separately in a non-installed state.

[0014] Compared with the prior art, the utility model provides a plastic PVC pipe with wear resistance, which has the following beneficial effects:

[0015] The plastic PVC pipe with wear-resistant function is provided with an outer covering shell, sliding teeth and an outer protective frame. Before the pipe structure is installed, the outer protective frame is first connected to establish a movable connection relationship through the cooperation of the sliding groove and the sliding teeth. After the pipe structure is installed, the water flows inside the pipe body. Due to the galvanized metal layer provided on the inner side, the alkaline or acidic substances in the water flow are difficult to directly corrode the pipe body. After the pipe body is installed and fixed, the cover plate on the inner side of the outer protective frame shields the pipe body from the outside, thereby improving the overall impact resistance of the pipe body and enhancing the overall toughness of the pipe. The isolation rubber ring annularly distributed on the periphery of the outer protective frame cushions the pipe body, so that the pipe body keeps a distance from the surrounding installation environment, so that the pipe not only enhances the external protection and impact resistance, but also has the effect of wear resistance and erosion resistance. Its split design allows the outer protective frame and the pipe body to be completely separated, and the split installation is more convenient in a narrow environment.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 In this embodiment: a plastic PVC pipe with wear resistance includes a pipe body 1, an outer shell 2, and a sliding tooth 3. The outer shell 2 is arranged on the outer end surface of the pipe body 1, and the outer shell 2 initially establishes protection for the pipe body 1. The sliding tooth 3 is arranged on the outer end surface of the outer shell 2, and the sliding tooth 3 establishes a connection with the slide groove 403;

[0023] An outer protective frame 4 is also provided on the periphery of the outer shell 2, and the outer protective frame 4 provides protection for the pipeline body 1 on the outer layer of the pipeline body 1;

[0024] The outer protection frame 4 also includes a cover plate 401, an isolation rubber ring 402, and a slide groove 403. The cover plate 401 is fixedly connected to the inner end surface of the outer protection frame 4, the isolation rubber ring 402 is sleeved on the outer end surface of the outer protection frame 4, and the slide groove 403 is opened on the inner side of the cover plate 401.

[0025] In this embodiment, the pipe body 1 further includes a tantalum-plated metal layer 101 and an epoxy resin coating 102. The tantalum-plated metal layer 101 is coated on the inner wall surface of the pipe body 1 by electroplating, and the epoxy resin coating 102 is coated on the outer surface of the pipe body 1 by external brushing. The isolation rubber ring 402 is an annular rubber ring structure as a whole, made of plastic material, and has the ability to bend and stretch at multiple angles. Five groups are provided and are equidistantly distributed according to the laying path of the pipe body 1.

[0026] Specifically, the isolation rubber ring 402 made of plastic material can cushion the pipe body 1 while providing an isolation space of a certain distance around it, and the isolation rubber ring 402 with high flexibility can be applied to pipes of different diameters;

[0027] In this embodiment, four groups of slide grooves 403 and slide teeth 3 are provided, and there is a sliding connection relationship between them; the pipeline body 1 establishes a movable connection relationship with the outer shell 2 by plugging; the outer shell 2 and the outer protection frame 4 can be stored and transported separately in the non-installed state;

[0028] Specifically, the outer shell 2 and the outer protection frame 4 are stored and transported separately in the non-installed state, so that the pipeline body 1 can be installed more flexibly in a narrow environment.

[0029] The working principle and use process of the utility model are as follows: before the installation of the pipeline structure, the outer protection frame 4 is first connected to the sliding tooth 3 through the slide groove 403 to establish a movable connection relationship. After the pipeline structure is installed, the water flows inside the pipeline body 1. Because the galvanized metal layer 101 is arranged on the inner side, the alkaline or acidic substances in the water flow are difficult to directly corrode the pipeline body 1. After the pipeline body 1 is installed and fixed, the cover plate 401 on the inner side of the outer protection frame 4 shields the pipeline body 1 from the outside, thereby improving the overall impact resistance of the pipeline body 1 while also enhancing the overall toughness of the pipeline. The isolation rubber ring 402 annularly distributed on the periphery of the outer protection frame 4 cushions the pipeline body 1, so that the pipeline body 1 keeps a distance from the surrounding installation environment, so that the pipeline not only enhances external protection and impact resistance, but also has the effect of wear resistance and erosion resistance. Its split design allows the outer protection frame 4 and the pipeline body 1 to be completely disassembled.
