Shell and lower half shell, the upper half shell and lower half shell are fastened and are sheathed on outside air hose each other, the bottom surface periphery and lower half of upper half shell
The first sealing ring is folded between the bottom surface periphery of shell, the second sealing ring is folded between the both ends of leak stopping tube body and air hose, the
Two sealing rings are stuck in corresponding annular positioning groove.
Preferably, first sealing ring is located between the bottom surface inner peripheral of upper half shell and the surface inner peripheral of lower half shell.
Preferably, the bottom surface inner peripheral of the upper half shell and the surface inner peripheral of lower half shell are recessed with arc groove, and two
The internal diameter of arc groove is respectively less than the outside diameter of the first sealing ring, and two parts up and down of the first sealing ring are embedded in corresponding arc respectively
In groove.
Preferably, the both ends inner wall of the leak stopping tube body is recessed with arc groove, the outboard section of second sealing ring
In arc groove.
The utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology
Scheme is understood：
By being concavely provided with multiple annular positioning grooves in the outer surface of air hose, when air hose somewhere is leaked out, at place two of leaking out
The second sealing ring is arranged in the corresponding annular positioning groove in side, then, the first sealing ring is placed between lower half shell and upper shell, so
Afterwards, by split snapping above and below upper half shell and lower half shell, to encase place of leaking out, fast blockage is realized, the utility model is simple in structure,
It is easy for installation quick, bring facility for construction operation.
More clearly to illustrate the architectural feature of the utility model and effect, come below in conjunction with the accompanying drawings with specific embodiment pair

Embodiment
It refer to shown in Fig. 1 to Fig. 3, that show the concrete structure of the preferred embodiment of the utility model, include
Air hose 10 and leak stopping tube body 20.
The outer surface of the air hose 10 is concavely provided with multiple annular positioning grooves 11, and the plurality of annular positioning groove 11 is along air hose 10
Axially spaced-apart is arranged.
The leak stopping tube body 20 includes upper half shell 21 and lower half shell 22, and the upper half shell 21 and lower half shell 22 are fastened each other
And be sheathed on outside air hose 10, it is folded with the first sealing ring between the bottom surface periphery of upper half shell 21 and the bottom surface periphery of lower half shell 22
30, the second sealing ring 40 is folded between the both ends of leak stopping tube body 20 and air hose 10, the second sealing ring 40 is stuck in corresponding annular
In locating slot 11.
In the present embodiment, first sealing ring 30 is located at the bottom surface inner peripheral of upper half shell 21 and the surface of lower half shell 22
Between inner peripheral.Also, it is recessed that the surface inner peripheral of the bottom surface inner peripheral of the upper half shell 21 and lower half shell 22 is recessed with arc
