Abstract
The utility model relates to a breather plug for an automotive drive axle. The improved breather plug structure enables connection between a breather plug cap and a plug body to be firmer, simpler and more reliable, and production cost is lowered. The breather plug for the automotive drive axle comprises a breather plug cap and a breather plug body. At least two grooves are formed in the outer wall of the breather plug cap, and each groove is provided with an inward-bent edge; the breather plug body is made of plastics, a step face is arranged on the top of the breather plug body, and the bent edges are fixedly clamped on the step face. The grooves are preferably two in number and opposite formed in the outer wall of the breather plug cap in the circumferential direction.
Description
Technical field
The utility model relates to a kind of improvement of cock body structure, particularly a kind of automobile drive axle breather stem vent plug.
Background technology
As shown in Figure 1, the total Chengdu of breather stem vent plug of the prior art is steel structure, between ventilation cock cap and ventilation cock body, uses welding manner to connect, its complex process, and cost is high.
Utility model content
For deficiency of the prior art, the utility model provides a kind of improved ventilation plug structure, makes the connection of ventilating between cock cap and cock body more firmly with simple and reliable, has reduced productive costs simultaneously.
In order to address the above problem, this kind of automobile drive axle breather stem vent plug, comprises ventilation cock cap and ventilation cock body, and the outer wall of this ventilation cock cap is provided with at least two grooves, and each groove is provided with the flanging of inside bending; This ventilation cock body is made of plastics and its top is provided with step surface, and described flanging fixes on this step surface.
Preferably, described groove is two and is circumferentially oppositely arranged along the outer wall of described ventilation cock cap.
The utility model is for the shortcoming of existing ventilation plug structure, a kind of new breather stem vent plug is provided, screw mating part changes non-threaded structure into, material changes sizing material into by rigid body, prevent the generation of fuel injection event, ventilation cock cap, by the improvement of structure, designs lock bolt structure, realize the connection of two parts by mechanical mode, reduced process costs.
