Description

Technical Field

[0001] The utility model relates to the technical field of HDPE pipes, in particular to an anti-vibration and anti-swaying HDPE pipe. Background Art

[0002] HDPE pipe is a thermoplastic polyolefin pipe produced by ethylene copolymerization. Its raw material HDPE is a highly crystalline, non-polar thermoplastic resin. HDPE pipe is a replacement product for traditional steel pipes and polyvinyl chloride drinking water pipes. It not only has good economic efficiency, but also has a series of advantages such as stable and reliable interfaces, material impact resistance, crack resistance, aging resistance, and corrosion resistance. However, the structure of the HDPE pipe in the prior art is relatively simple and the use effect is not good.

[0003] A query of the known prior art "CN 216045890 U, a non-slip and antibacterial PE pipe" records that "the utility model relates to the field of pipe technology, and discloses a non-slip and antibacterial PE pipe, including a pipe body and a fixed block and a connecting block fastened to the outside of the pipe body, the fixed block is located in front of the connecting block, and two groups of through holes are respectively opened inside the fixed block and the connecting block, and a slide groove is opened at the top of the through hole on the fixed block, and a handle is slidably connected inside the slide groove, and the bottom of the handle extends into the through hole and is fastened to the clamping rod. The non-slip and antibacterial PE pipe can increase the anti-slip property of the pipe body by arranging anti-slip textures on the outside of the pipe body, and prevent the pipe body from breeding bacteria by adding nano-scale antibacterial masterbatch in the pipe body, and through the cooperation between the protrusion and the connecting rope, the top block can be quickly popped out and pressed against the connecting block, so that the two groups of pipe bodies can be installed conveniently and stably, and the separation of the two groups of pipe bodies due to connection failure can be prevented."

[0004] However, the above-mentioned PE pipes in the prior art still have the following disadvantages: although the above-mentioned PE pipes are provided with anti-skid patterns on the outside of the pipe body, the anti-skid structure is relatively simple in design, lacks recognition, and has poor use effect.

A reinforcing rib 3 is also provided on the outer wall of the pipe body 1, and the reinforcing rib 3 is a plurality of evenly distributed ribs. Specifically, the outer wall of the pipe body 1 is divided into three parts: the left part, the middle part, and the right part. The reinforcing ribs 3 of the left and right pipe bodies 1 are of a linear structure. The reinforcing rib 3 of the middle pipe body 1 is mainly composed of a plurality of convex points 14, and the convex points 14 are in a "middle"-shaped structure as a whole, and are a plurality of evenly distributed ribs in an annular shape. The purpose of this setting is to integrally form reinforcement ribs on the outer wall of the pipe body, which is simple to manufacture.

It not only serves as a unique identification description and beautification effect of the pipe pattern, but also effectively plays an anti-seismic and anti-sway effect when the HDPE pipe is in use.

[0022] like Figure 1As shown: In this embodiment, a connecting ring 4 is provided at one end of the tube body 1, and a connecting protrusion 5 is provided at the other end. The connecting ring at one end of the tube body is connected and fixed with the connecting protrusion of the adjacent connecting tube body. The connecting ring 4 is also provided with a fastener 6; refer to Figure 2 As shown: the fastener 6 includes a fastening rod 7, a fastening plate 8, a compression spring 9 and an adjusting knob 10. The fastening rod 7 passes through the side wall of the connecting ring 4 and the two can move relative to each other. The fastening plate 8 is an arc-shaped structure and is arranged at the inner end of the fastening rod 7, that is, the fastening plate is located in the inner cavity of the connecting ring. A first inclined surface 11 is also provided on one side of the fastening plate 8; as shown in the figure, the first inclined surface is arranged on the outer side of the fastening plate. The compression spring 9 is arranged on the fastening rod 7 and is located between the fastening plate 8 and the side wall of the connecting ring 4; that is, the compression spring is located in the inner cavity of the connecting ring, and the adjusting knob 10 is arranged at the outer end of the fastening rod. The connecting protrusion 5 is also an arc-shaped structure, and a second inclined surface 12 is also provided on one side; the first inclined surface has the same structure as the second inclined surface.

The connection process of the pipe body: in the initial state, the compression spring naturally extends, and the fastening plate is in the path of the connecting protrusion, and there is a moving contact; that is, in the process of the connecting protrusion continuously entering the inner cavity of the connecting ring, the second inclined surface of the connecting protrusion begins to squeeze the first inclined surface of the fastening plate, so that the compression spring contracts and the fastening rod moves outward; until the connecting protrusion "crosses" the fastening plate, the compression spring releases energy to drive the fastening plate to reset, and the fastening plate forms a "blocking" engagement with the connecting protrusion. At the same time, in this state, the rubber sealing gasket is compressed by a part of the thickness, thereby ensuring the convenience, sealing and efficiency of the disassembly and connection between adjacent pipe bodies; saving time and effort, and more practical.
