Description
Technical field
The utility model belongs to exhaust field, is specifically related to a kind of breather plug.
Background technique
Breather plug Main Function is when transmission internal temperature raises, inner oil gas is discharged into air by breather plug, the discharge of fluid is stopped by filtrating equipment, maintain the balance of inner and outer air pressure, and though existing breather plug can meet ventilation, dirt exclusion capabilities and the discharge of restriction fluid, but drenching with rain for a long time, the complex working condition such as extra torrential rain time, its waterproof ability this problem weak is just completely exposed.
Model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of breather plug, to drench with rain for a long time or extra torrential rain time, still can prevent rainwater from entering operating mechanism inside by gearbox vent plug.
In order to achieve the above object, the utility model comprises the ventilation stopper rod matched, ventilation gag and ventilation cock cap, one end of ventilation stopper rod is provided with the Liu Fangtai being convenient to assemble and dismantle, ventilation cock cap is fixed on ventilation stopper rod, and opening is towards the ventilation end of ventilation stopper rod, ventilation gag is set on ventilation stopper rod, and be placed in breather plug cap, ventilation gag and ventilation cock cap interlock setting, and form U-shaped vent slot, ventilation stopper rod offers the vent covered in ventilation gag perpendicular to axial direction, ventilation stopper rod is provided with baffle plate, baffle plate is perpendicular to breather plug rod axis, ventilation gag, the first filtrating equipment is provided with between ventilation cock cap and baffle plate, the second filtrating equipment is provided with between ventilation gag and ventilation stopper rod.
Described ventilation gag is horn mouth shape, and bell-mouthed edge has the groove of ventilation.
The ventilation end of described ventilation stopper rod offers outside thread.
Compared with prior art, the utility model is provided with two filtrating equipments, after temp. of gear-shifting box raises, inner oil gas, air pressure are attracted on filtrating equipment, can not be easy to flow to air, can be attracted on filtrating equipment when the dust in the breather plug external world enters breather plug, breather plug inside cannot be entered, both decreased pollution of atmosphere, and ensured again in gearbox and can not enter excess dust; Perpendicular to breather plug rod axis direction, baffle plate is increased between ventilation cock cap and ventilation gag, this baffle plate is welded on breather plug and covers, baffle plate leaves gap with ventilation cock cap, the skirt section of ventilation cock cap is lengthened simultaneously, make rainwater enter breather plug, prevent the corrosion of operating mechanism inner body, avoid lubricant pollution.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
See Fig. 1, the utility model comprises the ventilation stopper rod 3 matched, ventilation gag 2 and ventilation cock cap 4, one end of ventilation stopper rod 3 is provided with the six side's platforms 6 being convenient to assemble and dismantle, the ventilation end of ventilation stopper rod 3 offers outside thread, ventilation cock cap 4 is fixed on ventilation stopper rod 3, and opening is towards the ventilation end of ventilation stopper rod 3, ventilation gag 2 is set on ventilation stopper rod 3, and be placed in breather plug cap 4, ventilation gag 2 and ventilation cock cap 4 interlock setting, and form U-shaped vent slot, ventilation stopper rod 3 offers the vent covered in ventilation gag 2 perpendicular to axial direction, ventilation stopper rod 3 is provided with baffle plate 5, baffle plate 5 is perpendicular to ventilation stopper rod 3 axis, ventilation gag 2, the first filtrating equipment 1 is provided with between ventilation cock cap 4 and baffle plate 5, the second filtrating equipment 7 is provided with between ventilation gag 2 and ventilation stopper rod 3, ventilation gag 2 is horn mouth shape, bell-mouthed edge has the groove of ventilation.
After temp. of gear-shifting box raises, inner oil gas, air pressure enter from ventilation stopper rod 3 internal port, the first filtrating equipment 1 is entered by the vent on ventilation stopper rod 3, gas is after the first filtrating equipment 1, flow out from the U-shaped vent slot ventilation gag 2 horn mouth, then discharged by the second filtrating equipment 7, baffle plate 5.Oil gas is attracted on filtrating equipment, can not be easy to flow to air.The dust in the breather plug external world can be attracted on filtrating equipment when entering breather plug, cannot enter breather plug inside.Because its ventilation cock cap 4 skirt section of the new breather plug of the utility model is longer, ventilation gag 2 is horn mouth shape, ventilation cock cap 4 and ventilation gag 2 are buckled together mutually, add baffle plate 5 simultaneously, rainwater ventilated cock cap 4, ventilation gag 2 and baffle plate 5 intercept outside filtrating equipment, make rainwater enter breather plug.The assembling of this breather plug and convenient disassembly, structure is simple, good manufacturability, excellent performance.
