Description

Technical Field

[0001] This utility model belongs to the field of nylon tubing technology, and in particular relates to a nylon tubing with interchangeable angles. Background Technology

[0002] Nylon tubing is widely used in fluid transport systems, such as cooling systems, fuel systems, and air lines, due to its advantages of low cost, light weight, and corrosion resistance. These tubing systems are usually connected to pipe or equipment components through joints, most of which are currently snap-fit ​​connections.

[0003] While snap-fit ​​connections offer the advantage of rapid installation, they have an inherent and insurmountable drawback: once snap-fitted, the relative angle between the connector and the pipe is permanently fixed and cannot be adjusted. In actual installation, due to manufacturing tolerances, limited installation space, and the complexity of the overall layout, slight angular deviations often occur between the pipe and equipment interfaces. Using snap-fit ​​connectors in such cases leaves installers with no room for adjustment, frequently leading to the following problems: 1. Installation difficulties: In order to align the fixed-angle connector with the equipment port, it is often necessary to forcibly twist the pipeline, making the installation process time-consuming and laborious.

[0004] 2. Introducing installation stress: Forcibly aligning the pipes will cause continuous torsional loads at the connection points. This initial stress will significantly reduce the fatigue life of the pipes and increase the risk of premature failure under vibration.

[0005] 3. Decreased sealing reliability: Unnatural twisting may affect the effective contact of the sealing surface inside the joint, which may lead to leakage in the long run.

[0006] 4. Using universal joints is an option, but this is not economical for large-scale, cost-sensitive nylon piping systems due to their high cost. Therefore, there is an urgent need for a nylon piping solution that allows for flexible angle adjustment. Summary of the Invention

[0007] The purpose of this invention is to provide a nylon pipe with interchangeable angles. The design of the upper and lower shells allows them to rotate freely, giving installers great flexibility. This enables them to steplessly and precisely adjust the joint to the optimal angle according to the actual docking conditions on site, completely solving the problem of installation alignment caused by angle deviation. After the angle is adjusted to the correct position, the upper and lower shells are permanently fixed at the connection point by welding. Welding fuses the two independent shells into a single integral structure without moving parts or relative displacement, which has high rigidity and high reliability. Its vibration and impact resistance far exceeds any mechanical connection method that relies on elastic buckles.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a nylon pipe with replaceable angle, including a pipe system, wherein the pipe system is provided with a plurality of pipe ends, and a connector mechanism is installed at each pipe end; The joint mechanism consists of an upper housing and a lower housing. The lower housing is rotatably disposed inside the upper housing for angle adjustment. The connection between the upper housing and the lower housing is fixed by welding for final fixation. The lower housing is integrally connected to a connecting pipe section at its tail end. The connecting pipe section is a straight pipe structure or a bent pipe structure with any bending angle between 0° and 90°. The end of the connecting pipe section is integrally provided with a barbed pipe joint, which is interference-fitted inside the pipe end and has an external clamping structure between the two.

[0009] Furthermore, the lower housing has an inner step, the upper housing has an outer step, and a sealing ring is provided between the inner step and the outer step.

[0010] Furthermore, a groove is formed between the outer step and the upper shell, and the gap at the front end of the lower shell is disposed within the groove.

[0011] Furthermore, the upper housing has a locking groove structure on the circumferential side away from the lower housing, and a spring wire lock is provided in the locking groove structure of the upper housing.

[0012] Furthermore, a positioning ring is provided at the connection between the barbed pipe joint and the pipe section, and the end face of the pipe is in contact with the positioning ring.

[0013] Furthermore, the lower housing has a raised ring on its circumferential side at the tail end, and the upper housing end is fitted with the raised ring and there is a welding point between them.

[0014] This utility model has the following beneficial effects: This utility model, through the design of the upper and lower shells, allows them to rotate freely, giving installers great flexibility. This enables them to steplessly and precisely adjust the joint to the optimal angle according to the actual docking conditions on site, completely solving the problem of installation alignment caused by angle deviation. After the angle is adjusted to the correct position, the upper and lower shells are permanently fixed at the connection point by welding. Welding fuses the two independent shells into a single integral structure without moving parts or relative displacement, which has high rigidity and high reliability. Its vibration and impact resistance far exceeds any mechanical connection method that relies on elastic buckles.
