Further, the outer surface of the cylindrical shell is circumferentially arranged multiple annular grooves.
Further, the annular groove is zigzag annular groove.
Further, the endoporus is the closed blind hole in one end.
Further, the diameter of bore is less than steel ball sphere diameter.
Further, the difference in diameter of diameter of bore and steel ball sphere diameter is 0.2~0.3mm.
Further, the difference in diameter of diameter of bore and steel ball sphere diameter is 0.25mm.
Compared with the existing technology, the utility model achieves following advantageous effect：
1, a kind of novel ball of the utility model rises plug, and the oral area of the endoporus of cylindrical shell is provided with isometrical with steel ball
Arc neck, steel ball are embedded in arc neck, and arc neck and steel ball face paste are filled the span of a man's arms steel ball, and contact area is big, and connection can
It leans on, steel ball can be effectively prevent to fall off, reliable in quality, qualification rate height.
2, a kind of novel ball of the utility model rises plug, the outer surface of cylindrical shell it is circumferentially arranged there are one or it is multiple
Annular groove, in use, steel ball is completely forced into the endoporus of cylindrical shell, steel ball makes cylinder outwardly against the side wall of cylindrical shell
Shell swells, and coordinates the annular groove on the outer surface of cylindrical shell, makes the complete swelling of plug, good airproof performance；Specially designed sawtooth
Shape annular groove, dilatancy performance is good, can further increase ball and rise the sealing performance of plug.
Description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings.
Fig. 1 is that the ball of the utility model rises the structural schematic diagram of plug.
Fig. 2 is the structural schematic diagram of cylindrical shell.
In figure：1, cylindrical shell；2, steel ball；3, endoporus；4, arc neck；5, annular groove.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, the technical solution in embodiment is carried out it is clear, complete
Ground describes.Obviously, described embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.
Based on the embodiments of the present invention, institute that those of ordinary skill in the art are obtained without creative efforts
There is other embodiment, shall fall within the protection scope of the present invention.
As shown in Fig. 1~2, a kind of novel ball rises plug, including cylindrical shell 1 and steel ball 2, the cylindrical shell 1 it is interior
Portion is provided with endoporus 3, and the oral area of the endoporus 3 is provided with the arc neck 4 isometrical with steel ball 2, and the steel ball 2 is embedded in circular arc
In card slot 4.
Diameter is slightly less than 2 diameter of steel ball at the notch of arc neck 4, and steel ball, which can consolidate, to be embedded in arc neck 4, circle
Arc card slot 4 and 2 face paste of steel ball are filled the span of a man's arms steel ball 2, and contact area is big, and connection is reliable, steel ball 2 can be effectively prevent to fall off, quality
Reliably, product qualification rate is high.
Preferred scheme, the outer surface of the cylindrical shell 1 is circumferentially arranged multiple annular grooves 5.In use, by steel ball 2
It is completely forced into the endoporus 3 of cylindrical shell 1, steel ball 2 makes cylindrical shell 1 swell outwardly against the side wall of cylindrical shell 1, cooperation
Annular groove 5 on the outer surface of cylindrical shell 1 makes the complete swelling of plug, good airproof performance.
