[0002] Polyethylene pipe is a type of plastic pipe that is corrosion-resistant, impact-resistant, and has a long service life. It is widely used in many fields, such as building water supply and drainage, chemical fluid transportation, and garden irrigation.
[0003] Existing conventional PE pipe fittings have poor anti-slip performance. During installation and operation, especially when manual handling, connection, or adjustment of pipe positions is required, the smooth surface of the pipe fittings makes it difficult for operators to hold them firmly, which can easily cause the pipe fittings to slip. This not only affects work efficiency but may also cause damage to the pipe fittings or even safety accidents. In addition, PE pipe fittings have limited wear resistance. During long-term use, especially in situations where there is frequent contact and friction with other objects, the outer surface of the pipe fittings is easily worn, resulting in appearance damage and shortening the service life of the pipe fittings.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4 The present invention provides the following technical solution:
[0025] A non-slip PE pipe fitting includes a pipe fitting body 1, with two annular blocks 2 sleeved on the surface of the pipe fitting body 1, and fixing blocks 3 provided on the surface of both annular blocks 2, with a first protrusion 4 arranged in an annular shape on the surface of the fixing blocks 3.
[0026] The main body of the pipe fitting 1 includes a PE pipe body 11, a covered pipe 12 is provided on the surface of the PE pipe body 11, an anti-corrosion layer 13 is provided on the inner wall of the PE pipe body 11, and a wear-resistant layer 14 is provided on the surface of the covered pipe 12.
[0027] In this embodiment, by using a composite design for the pipe fitting body 1, the service life of the pipe fitting body 1 is greatly extended in terms of corrosion resistance and wear resistance, enabling it to adapt to the requirements of transporting various corrosive fluids and high-wear environments. This reduces the maintenance cost and replacement frequency of the pipeline system. The annular block 2 and the fixed block 3, along with the first protrusion 4 on them, form an effective anti-slip system, facilitating safe and convenient handling, installation, and operation of the pipe fitting body 1 under various working conditions. This effectively avoids safety accidents and low work efficiency caused by the slippage of the pipe fitting body 1.
[0028] Specifically, such as Figure 3 As shown, the anti-corrosion layer 13 is composed of epoxy resin coating and is uniformly coated on the inner wall of the PE pipe body 11.
[0029] Specifically, such as Figure 3 As shown, the wear-resistant layer 14 is composed of ultra-high molecular weight polyethylene coating and is uniformly coated on the surface of the tube 12.
[0030] Specifically, such as Figure 4 As shown, an adhesive layer 5 is provided between the opposite sides of the PE pipe body 11 and the covered pipe 12, and the adhesive layer 5 is evenly distributed between the two.
[0031] Specifically, such as Figure 4 As shown, the adhesive layer 5 is made of acrylic adhesive and is evenly coated between the PE pipe body 11 and the covered pipe 12.
[0032] In this embodiment: an anti-corrosion layer 13, composed of epoxy resin coating, is uniformly applied to the inner wall of the PE pipe body 11. Epoxy resin has excellent adhesion and chemical corrosion resistance, allowing the anti-corrosion layer 13 to form a dense protective film, effectively isolating the fluid from direct contact with the PE pipe body 11 material, preventing the pipe wall from gradually thinning and perforating due to corrosion, thereby extending the service life of the pipe body 1. A wear-resistant layer 14, composed of ultra-high molecular weight polyethylene coating, is uniformly applied to the surface of the coated pipe 12. Ultra-high molecular weight polyethylene has extremely high wear resistance, impact resistance, and self-lubricating properties, which can reduce wear during the use of the pipe body 1, maintain the structural integrity and appearance quality of the pipe body 1, and further extend the overall service life of the pipe body 1. The bonding layer 5 between the PE pipe body 11 and the coated pipe 12 on opposite sides is composed of acrylic adhesive and uniformly applied. Acrylic adhesive has good bonding strength and stability, which can tightly bond the PE pipe body 11 and the coated pipe 12 together, ensuring that the two will not easily separate or form gaps under different stress conditions, making the overall structure of the pipe body 1 more stable and reliable.
[0033] Specifically, such as Figure 1 , Figure 2 As shown, the surface of the covering tube 12 is provided with a groove 6 arranged in an annular shape, and the inner wall of the annular block 2 is provided with a second protrusion 7, and the second protrusion 7 is located inside the groove 6.
[0034] In this embodiment, by setting the groove 6 and the second protrusion 7, the annular block 2 is accurately positioned and stably connected on the covered pipe 12, which can effectively prevent the annular block 2 from axial or circumferential displacement during the use of the pipe body 1, ensuring that the annular block 2 and its anti-slip structure are always in the correct working position. Even under vibration, impact or external force pulling, it can maintain a firm connection, thereby continuously providing reliable anti-slip function for the pipe body 1 and improving the stability and durability of the anti-slip structure.
[0035] Specifically, such as Figure 2 As shown, a rotating shaft structure is provided between the right sides of the two annular blocks 2, and the two annular blocks 2 are rotatably connected through the rotating shaft structure.
[0036] Specifically, such as Figure 2 As shown, a connecting block 8 is provided on the left side of the annular block 2, and the two connecting blocks 8 are connected by a bolt structure.
[0037] In this embodiment, the relative rotational connection between the two annular blocks 2 is achieved through the rotating shaft structure between them, which makes it easy to install the annular blocks 2 on the surface of the pipe body 1. Furthermore, the use of the connecting block 8 and the bolt structure makes it easy to securely install the annular blocks 2 on the surface of the pipe body 1, preventing them from moving freely.
[0038] Working principle: When the pipe fitting body 1 is in use, two annular blocks 2 are fitted onto the surface of the pipe fitting body 1, with the second protrusion 7 positioned inside the groove 6. Then, the two connecting blocks 8 are fastened together using bolts, thus fixing the annular blocks 2 to the surface of the pipe fitting body 1. Therefore, the annular blocks 2, the fixing block 3, and the first protrusion 4 on it form an effective anti-slip system, facilitating safe and convenient handling, installation, and operation of the pipe fitting body 1 under various working conditions. This effectively avoids safety accidents and low work efficiency caused by the pipe fitting body 1 slipping. Furthermore, the anti-corrosion layer 13 effectively isolates... The absence of direct contact between the fluid and the PE pipe body 11 material prevents the pipe wall from gradually thinning and perforating due to corrosion, thereby extending the service life of the pipe body 1. Through the wear-resistant layer 14, the structural integrity and appearance quality of the pipe body 1 can be maintained during the use of the pipe body 1, further extending the overall service life of the pipe body 1. Through the adhesive layer 5 between the PE pipe body 11 and the covered pipe 12 on opposite sides, the PE pipe body 11 and the covered pipe 12 can be tightly bonded together, ensuring that the two will not easily separate or form gaps under different stress conditions, making the overall structure of the pipe body 1 more stable and reliable.
[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
