Abstract
Description
Technical Field
[0001] This utility model relates to a novel nylon tube structure for connection with olive-shaped fittings, belonging to the field of fitting equipment technology. Background Technology
[0002] In the field of automotive engineering, the transmission system for media such as coolant and fuel is a key component ensuring the normal operation of vehicles. Traditional liquid cooling systems mostly use rubber materials. However, with the development of materials science, nylon tubing, with its excellent aging resistance and significant weight reduction advantages, has gradually become an ideal alternative to rubber tubing.
[0003] It is worth noting that some automotive injection-molded components, such as water pumps and valves, have standardized olive-shaped interfaces. Based on platform design principles, this structure is often retained. This situation necessitates the introduction of a rubber hose as a transitional connector when assembling nylon tubing with the olive-shaped interface. Specifically, this connection solution requires additional rubber hose and adapter: one end of the adapter uses a bamboo-like structure to connect to the nylon tubing, while the other end adapts to the olive-shaped interface and connects to the rubber hose, ultimately achieving connection to the corresponding component's olive-shaped interface via the rubber hose. This connection method has significant drawbacks, not only substantially increasing material procurement costs and assembly time, but also increasing the risk of media leakage due to the increased number of connection points, posing a potential threat to the reliability and safety of the automotive system.

[0022] The following is a specific embodiment of this utility model with reference to the accompanying drawings, and the structure of this utility model is described in detail. It should be noted that the scope of application of this utility model is not limited to the following embodiment; all similar structures based on this utility model are within the scope of application of this utility model.
[0023] This utility model discloses a novel nylon tube structure for connection with an olive-shaped connector, such as... Figures 1-5 As shown, the nylon tube includes:
[0024] A novel nylon tube structure for connection with an olive-shaped fitting, characterized in that the nylon tube structure comprises:
[0025] The nylon tube body 1 has an extrusion 2 on it. The extrusion 2 can prevent the sealing connector 4 from falling off the nylon tube body 1. The front end of the nylon tube body 1 has several shrinkage notches 3. The nylon tube is relatively hard compared to the rubber tube. The shrinkage notches 3 of the nylon tube body 1 can reduce the gap when the clamp 7 is tightened, thus playing a tightening role.
[0026] The sealing connector 4 is embedded inside the nylon tube body 1, and the two side walls of the sealing connector 4 are provided with protrusions 5 that cooperate with the extrusion 2.
[0027] As a further description of this utility model, the opening of the nylon tube body 1 is provided with a flange 6, and the edge of the flange 6 can be used for the installation and positioning of the sealing connector 4.
[0028] As a further description of this utility model, such as Figure 6 As shown, a clamp 7 is provided on the outer wall of the nylon tube body 1 between the flange 6 and the extrusion 2. The clamp 7 is used to tighten the nylon tube body 1 and the sealing connector 4 onto the handpiece olive bag 8.
[0029] The working principle of this utility model is as follows:
[0030] The nylon tube body 1 is first extruded and then the axial limiting protrusion 5 structure of the sealing connector 4 is made. The extrusion 2 can prevent the sealing connector 4 from falling off the nylon tube body 1. Then the nylon tube body 1 is subjected to a flanging process. At this time, the end flanging 6 is tightened on the outer wall of the nylon tube body. The edge of the flanging 6 can be used for the installation and positioning of the sealing connector. Since the nylon tube is relatively hard compared to the rubber tube, four shrinkage notches 3 are made in the circumference of the nylon tube for connection and tightening. The sealing connector 4 is embedded in the inside of the nylon tube body 1 for sealing connection. The clamp 7 and the sealing connector 4 squeeze the flanging 6 into a 90-degree state. When the hand piece olive bag 8 is connected to the nylon tube body 1, the external clamp 7 is used to tighten the nylon tube body 1 and the sealing connector 4 onto the hand piece olive bag 8.
[0031] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this invention.
