Description

Technical Field

[0001] This utility model relates to the field of injection molded pipe fittings, and in particular to a water-assisted plastic pipe for engine accessories. Background Technology

[0002] Plastic pipes are generally made from synthetic resins, specifically polyester, with the addition of stabilizers, lubricants, and plasticizers. They are manufactured through extrusion in a pipe-making machine using a "plastic" method. They are mainly used for piping in building water supply systems, drainage, ventilation, and sewage systems; underground drainage systems; rainwater pipes; and conduits for electrical wiring. Water-assisted injection molding technology, however, is a relatively new technology. It has only been six years since the German Institute for Plastics Processing (IKV) published its initial results, yet it has been developing rapidly. Shortly after its invention, water-assisted injection molding was used to produce parts for supermarket shopping carts. Subsequently, it was used to mass-produce handles and large-section rod-shaped plastic parts. In practical production, water-assisted injection molding technology is increasingly being used for plastic parts with functional spaces or flow channels.

[0003] Existing engine water-assisted plastic hoses are pipe connection parts used in engine oil and water systems. They facilitate quick connection and assembly of two or more sets of pipes. However, due to the spliced ​​structure, tiny gaps inevitably exist between the hose connection and the pipes on either side, making this a relatively weak point in the pipe structure. This leads to frequent cracking and damage at the connection point due to strong water pressure. Furthermore, existing engine water-assisted plastic hose connectors are inconvenient to install and use in the confined space of a car engine, and the pipe joints are not secure enough, often resulting in loosening. Additionally, this pipe connection structure lacks structural reinforcement at the connection point, resulting in poor structural strength and susceptibility to breakage. Utility Model Content

[0004] The purpose of this utility model is to provide a water-assisted plastic pipe for engine accessories, which solves the problems of adaptability and secure connection of the water-assisted plastic pipe.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a water-assisted plastic pipe for configuring engine accessories, including a pipe body, a port connection end structure, and an external fixing component. The port connection end structure includes an upper connection port structure, a lower connection port structure, and a side upper connection port structure connected to the pipe body. The external fixing component includes an upper fixing connector structure located on the upper part of the pipe body and an inner and outer extension fixing connector structure located on the upper side of the lower connection port structure. The upper connection port structure includes an upper interface, an upper limiting stop located on the upper part of the upper interface, and an upper extension mounting platform located on the upper part of the upper limiting stop. The lower connection port structure includes a lower interface and a lower mounting cone located on the upper part of the lower interface. The side upper connection port structure includes a side upper lead-out cavity and a side upper connection interface located on the upper part of the side upper lead-out cavity.

[0006] The pipe body is a contoured bent pipe.

[0007] The aforementioned upper fixed connection structure includes an upper fixed seat located on the upper part of the pipe body and an upper bolt seat located on the upper part of the upper fixed seat.

[0008] The inner-side extension fixed connection structure includes an inner-side connecting platform on the upper tube of the lower end connection structure and an inner-side extension seat on the outer side of the inner-side connecting platform.

[0009] A sealing ring is provided in the upper limiting stop.

[0010] The beneficial effects of this utility model are as follows: The upper, lower, and side upper end connection structures of the main connecting pipe enhance the structural strength of the connector and other components without increasing its external volume. The external fixing components ensure a more stable connection and prevent misalignment or detachment. The pipe body's conformal design, adapted to the shape of a car engine, provides excellent resistance to impact and vibration forces on the connector's outer wall. The unique inner hole shape of the water-assisted plastic pipe, manufactured using a water-assisted process, enhances the pipe's structural strength and improves molding efficiency.
