Embodiment 1

[0021] specific embodiment figure 1 , figure 2 and image 3 As shown, the present invention includes a connection interface 1, a limiting boss 2, an interface groove 3, an O-ring 4, a plastic tube 5, and a fixing clip 6. The limiting boss 2 and the interface groove 3 are arranged on the connecting interface 1 On the top, the O-ring 4 is arranged in the interface groove, and the fixing clamp 6 is arranged on the outer wall of the plastic pipe 5; the plastic pipe 5 is connected with the connection interface 1, and is sealed by the O-ring 4 , and by the limit boss 2 and the fixed clamp 6 are fastened, and the O-ring 4 is an EPDM rubber sealing ring; the plastic pipe 5 is a plastic light pipe, and is a single-layer pipe, and the material is PA6. It can be seen from the figure that this embodiment has only one O-ring and one limiting boss 2 .

Embodiment 2

[0023] specific embodiment Figure 4 As can be seen from the figure, there are two limiting bosses 2 in this embodiment, the O-ring is eliminated, and the plastic pipe 5 has corrugations in part.

Embodiment 3

[0025] specific embodiment Figure 5 As shown, it can be seen from the figure that in this embodiment, there is a limiting boss 2 and an O-ring 4, and a part of the plastic pipe 5 has corrugations.

Abstract

The invention discloses a connecting pipe device in the technical field of liquid conveying pipelines. A connecting connector, a plastic pipe, a limiting boss, a connector groove, a seal component anda fixing clamp are included. The limiting boss and the connector groove are formed in the connecting connector, and the seal component is arranged in the connector groove. The fixing clamp is arranged on the outer wall of the plastic pipe. The plastic pipe is connected with the connecting connector, sealed through the seal component and fastened through the limiting boss and the fixing clamp. Theconnecting pipe device is reasonable in design, the vehicle weight is effectively reduced, the whole-vehicle running efficiency is improved, and the pulling disengaging force is greatly increased; and connection of the clamp and the plastic pipe is safe and effective for a long term, and life period safety of the system is greatly improved.

Description

technical field [0001] The invention relates to a connecting pipe device in the technical field of liquid delivery pipelines, in particular to a connecting pipe device that can effectively reduce the weight of a vehicle. Background technique [0002] When the car is running, the power unit of the car includes gasoline engine, diesel engine, drive motor, electronic control unit, lithium battery pack and other battery packs will generate heat when working, in order to avoid damage caused by overheating and combustion explosion , These auto parts that may be overheated must be cooled by coolant. At present, the most widely used pipe material in automobiles is EPDM, but the thickness of the rubber must reach more than 4mm, and the weight is relatively heavy. Big. In addition, the existing cooling pipeline system tends to use a large number of plastic pipelines (including bellows), but the sealing structure of the existing technical solutions is as follows: plastic pipelines and...
