For HRC39-42 ° of screw.
As a kind of preferred scheme of automobile hub throat taps, the two ends of the pipe plug screw body are equipped with bevelling angle knot
Structure.
As a kind of preferred scheme of automobile hub throat taps, one end diameter of the pipe plug screw body is more than the other end
Diameter.
As a kind of preferred scheme of automobile hub throat taps, major diameter one end of the pipe plug screw body offers six
Corner apertures.
As a kind of preferred scheme of automobile hub throat taps, the hole depth T values of the hexagon ring are 6mm-12.8mm.
As a kind of preferred scheme of automobile hub throat taps, the length L values of the pipe plug screw body are 11mm-
24mm。
It is used as a kind of preferred scheme of automobile hub throat taps, the bevelling angle of major diameter one end of the pipe plug screw body
Structure concaves 1-5 °.
It is used as a kind of preferred scheme of automobile hub throat taps, the bevelling angle of minor diameter one end of the pipe plug screw body
Structure concaves 0.3-2 °.
As a kind of preferred scheme of automobile hub throat taps, the pipe plug screw body is forged and pressed by multistation cold forging machine
Shaping.
The beneficial effects of the utility model are：
The utility model proposes a kind of automobile hub throat taps, the pipe plug screw body of the automobile hub throat taps is in positive round
Platform shape, the taper angle of positive truncated cone-shaped is 3 ° of 34 ˊ, and pipe plug screw body is to aoxidize film process by surface black and be heat-treated hard
The screw for HRC39-42 ° is spent, therefore, screw intensity and precision are high, stability, the assembling for effectively improving automotive hub operating are suitable
With property, security and long-acting usability, and ponding can be played, effectively prevent air pressure leak case after assembling.

Embodiment
To make the utility model technical problem solved, the technical scheme used and the technique effect reached clearer,
The technical scheme of the utility model embodiment is described in further detail below in conjunction with accompanying drawing, it is clear that described reality
It is only a part of embodiment of the utility model to apply example, rather than whole embodiments.Based on the embodiment in the utility model,
The every other embodiment that those skilled in the art are obtained under the premise of creative work is not made, belongs to this practicality new
The scope of type protection.
As depicted in figs. 1 and 2, present embodiment proposes that a kind of automobile hub throat taps includes pipe plug screw body 1, throat taps
Screw body 1 is in positive truncated cone-shaped, and the taper angle of positive truncated cone-shaped is 3 ° of 34 ˊ, and pipe plug screw body 1 is aoxidized by surface black
