Embodiment 1

[0048] This embodiment provides a fixing tool for a fuel pipe, including a plugging tool at the end of the rubber hose, and a fixing tool for a quick connector connected to the fuel pipe; the fixing tool for the quick connector includes a counterpart 4, the counterpart 4 One end has a cylindrical cavity, the inner wall of the cylindrical cavity has an annular groove, and a sealing ring is arranged in the annular groove for connecting the inner side wall of the cylindrical cavity with the outer side wall of the quick connector; The other end of the piece is provided with a hollow cylindrical channel 5, which is used for connecting the intake pipe to the quick connector.

[0049] In this embodiment, the quick connector is matched with the fixed tool of the quick connector, that is, a standard quick connector is adapted to a standard fixed tool, and when in use, different quick connector fixed tools are replaced according to different quick connectors.

[0050]In this embodiment,...

Embodiment 2

[0054] The fixing tool for the fuel hose provided in this embodiment includes the plugging tool for the rubber hose end, and also includes the fixing tool for the quick connector connected to the fuel pipe; the fixing tool for the quick connector includes a counterpart 4, one end of the counterpart 4 It has a cylindrical cavity, which can seal the cylindrical cavity and the quick connector when the quick connector is inserted into the cylindrical cavity; the other end of the counterpart is provided with a hollow cylindrical channel 5, which is used to allow the air inlet pipe to pass through and connect with the quick connector. The quick joint connection also includes a handle 6 and a claw 7, one end of the handle 6 is fixedly connected to one end of the claw 7, and the connection angle between the handle 6 and the claw 7 is greater than 90 degrees and less than 180 degrees; The other end of the claw 7 has a limit projection, the protruding direction of the limit projection is...

Embodiment 3

[0059] The fixing tool for the fuel hose provided in this embodiment has two lugs arranged in parallel, and also includes a torsion spring 8, the spring body of the torsion spring 8 is located between the lugs, and the torsion spring 8 One end is parallel to the handle, and the other end is parallel to the outer wall of the counterpart; the connecting pin passes through the projection, a lug, the spring hole of the torsion spring 8 and the other lug and fixes it.

[0060] As an alternative to this embodiment, there are two protrusions, which are respectively arranged on the outer sides of the two protrusions. Such an arrangement can make the fixing between the protrusions and the protrusions stronger and prevent the The position of the tab is shifted due to the force.

[0061] As an alternative to this embodiment, the torsion spring can be replaced by a general compression spring, one end of the compression spring is connected to the handle, and the other end of the compressio...

Abstract

The invention relates to the technical field of hose detection, and especially relates to a hose-end plugging tool of a fuel hose, a rapid joint fixation tool and an airtightness detection device. The hose-end plugging tool comprises a sleeve, wherein the inner side wall of one end of the sleeve is provided with an annular groove, and the other end is connected with an air inlet pipe; the annular groove is internally provided with a sealing ring; the tool further comprises a cylindrical rubber block; and the sealing ring sleeves the outer side wall of the rubber block, a cylindrical groove is arranged at one end, which is away from the air inlet pipe, of the rubber block for connection with the fuel hose. Since the sleeve of the hose-end plugging tool is full of air after a fuel pipe is inserted into the cylindrical groove, the outer surface of the rubber block is extruded to deform, the rubber block becomes smaller, and the hose end of the fuel pipe is locked. According to the invention, the problem of airtightness detection through plugging the hose by use of hands for long in the prior art is avoided, the problem of wrong judgment caused by manual operation is also avoided, and the labor cost is decreased.

Description

technical field [0001] The invention relates to the technical field of rubber hose detection, in particular to a fixing tool for a fuel pipe and an airtightness detection device for the fuel hose. Background technique [0002] At present, the fuel pipeline inspection in the automobile industry generally uses water inspection equipment to detect, that is, to use water as the medium, put the fuel pipe into a container filled with water, manually seal one end of the fuel hose, and pass in a certain pressure of air at the other end to ensure Press for a while, and observe whether there are air bubbles leaking from the fuel pipe, so as to judge whether the fuel pipe is leaking. [0003] The existing technical solutions are relatively backward, and only the presence of air bubbles is used as the basis for judging whether the fuel pipe leaks. Since these judgments are all made by humans, the tiny air bubbles that appear due to the slight leakage of the fuel pipe are easily overlook...
