Abstract
The utility model provides a water-proof ventilation plug assembly, which comprises a ventilation plug main body, wherein a shaft neck part on the tail part of the ventilation plug main body matched with an axle housing is provided with taper threads through processing; the head part of the ventilation plug main body has an outer hexagonal structure or an inner hexagular structure; the inside of the ventilation plug main body is provided with a blind hole which extends from the tail part to the head part; the shaft neck at the lower end of the ventilation plug main body is provided with a radial outlet communicated with the blind hole; the junction between the radial outlet and the blind hole is provided with a separation blade which inclines to the center line of the blind hole; the radial outlet is coated with a rubber joint; a connector of the rubber joint is provided with a zigzag structure; and a rubber hose is connected to the connector of the rubber joint and is clamped tightly through a pipe clamp. When the water-proof ventilation plug assembly is used in an axle housing, the separation blade prevents lubricating oil in a case from entering the outlet so as to avoid oil leakage and ventilation influence; and the longer rubber hose is exposed, so that under the condition of not influencing the ventilation, the water-proof ventilation plug assembly can effectively prevent external water and dust from entering to avoid the blocking of an air outlet.
Description
Technical field
The utility model relates to the breather stem vent plug assembly that uses in a kind of vehicle bridge.
Background technology
At present, the breather stem vent plug assembly that uses in vehicle bridge mostly is the through type Rubber Parts greatly, adopt polished rod directly to insert in the axle housing unthreaded hole, and the outer end portion of exposing axle housing does not have the dust and water protection device, breather stem vent plug get loose leakage of oil, water inlet often appear in the vehicle bridge use like this, situation about stopping up influences the use of vehicle bridge.
For this reason, need a kind of performance-oriented waterproof breather stem vent plug of new design, can stop the lubricating oil in the axle housing to spatter seepage outward, also can prevent outside water and dust go into to incline, in order to avoid stop up vent.Just under this design concept, we are newly developed a kind of breather stem vent plug assembly that is different from conventional confguration fully can play the effect of anti-water inlet and anti-leakage of oil simultaneously.
Summary of the invention
The utility model proposes a kind of waterproof breather stem vent plug assembly, to have solved in the vehicle bridge traditional breather stem vent plug easily get loose leakage of oil, water inlet, blocking problem, can stop the lubricating oil in the axle housing to spatter seepage outward, also can prevent outside water and dust go into to incline, in order to avoid stop up vent.
The technical solution adopted in the utility model is: a kind of waterproof breather stem vent plug assembly, comprise the breather stem vent plug body, taper thread is processed at breather stem vent plug body afterbody and axle housing engage journal position, breather stem vent plug body head is outer hexagonal structure or interior hexagonal structure, the breather stem vent plug body interior is provided with the blind hole of extending to head from afterbody, it is characterized in that: end journal is provided with radially to export and communicates with blind hole under the head of breather stem vent plug body, and radially outlet is provided with to blind hole line of centers bevelled catch with the blind hole intersection; Radially the exit is surrounded by rubber nipple; The connector of rubber nipple is provided with zigzag structure, and a rubber tube is connected on the connector of rubber nipple, clamps by a pipe clamp.
To further improvement in the technical proposal, be to be connected with the cone rubber shaft clevis at breather stem vent plug body afterbody.
Beneficial effect: the utility model applies on the axle housing, and catch stops the interior lubricating oil of bridge to enter the exit, in order to avoid leakage of oil and influence ventilation; Because it is longer that rubber tube exposes, under the situation that does not influence ventilation, can effectively play like this and prevent entering of outside water and dust, in order to avoid stop up air extractor duct.The cone rubber shaft clevis can make things convenient for the breather stem vent plug assembly to be assemblied on the axle housing.

The specific embodiment
As shown in Figure 1, 2, 3, description the utility model is as follows: a kind of waterproof breather stem vent plug assembly, comprise breather stem vent plug body 1, taper thread 5 is processed at breather stem vent plug body afterbody and axle housing engage journal position, breather stem vent plug body head 2 is outer hexagonal structure, the breather stem vent plug body interior is provided with the blind hole 6 of extending to head from afterbody, and end journal is provided with and radially exports 3 and communicate with blind hole under the head of breather stem vent plug body, and outlet and blind hole intersection are provided with to blind hole line of centers bevelled catch 4; The exit is surrounded by rubber nipple 7; The connector of rubber nipple is provided with zigzag structure 8, is connected with cone rubber shaft clevis 9, one rubber tubes 10 at breather stem vent plug body afterbody and is connected on the connector of rubber nipple, clamps by a pipe clamp 11.
Breather stem vent plug body head 2 is outer hexagonal structure, is the convenient wrench turn, and outer hexagonal structure also can substitute with interior hexagonal structure.
Cone rubber shaft clevis 9 is set, and is to make things convenient for the breather stem vent plug assembly to be assemblied on the axle housing.Cone rubber shaft clevis 9 also can be cancelled.
