Description
Technical field
This utility model auto parts and components field, the specifically purge cock on a kind of automobile oil pan.
Background technology
In the lubricating system more oil change of the various internal combustion engines such as automobile engine and other machinery equipment, typically all
Used lubricating oil is released using the purge cock for being located at oil sump or tank bottoms.Its process is：Purge cock is first opened, will
Used oil in oil sump or fuel tank is released, and then screws and make purge cock to seal, then adds new machine oil.Due to spiral shell of draining the oil
The effect of plug is very simple, is exactly mainly the sealing after draining the oil and drain the oil when changing machine oil, therefore uses on the above-described equipment at present
Purge cock, its structure is a simple bolt plus sealing ring, or a magnetic core is added in plug screw is used for adsorbing
Iron filings in machine oil.Such working effect is poor, not with store function, while sealing ring can not well contact plug screw peace
Discharge hole, sealing is not up to optimization.
Utility model content
The purpose of this utility model is to provide one being capable of the dirty plug screw of oil in reserve bottom shell.
To realize such purpose, this utility model is provided：
A kind of purge cock on automobile oil pan, the purge cock include purge cock body, purge cock nut and
The plug screw screw thread being located on purge cock body, described purge cock is arranged in the spiro pluging hole of fuel tank, described plug screw screw thread
With spiro pluging hole screw-internal thread fit and screw, the end of described purge cock body is provided with for storing the dirty groove of dirty storage.
It is described to store up dirty groove bottom for inclined plane.
The dirty groove of the storage is provided with mesh screen, mesh screen area less than the dirty groove area of storage, the mesh screen be located at the dirty groove location of storage compared with
Low side top.
Store up dirty groove inwall to be provided with for the flat thin magnet of adsorbing metal impurity.
The section of the nut is polygon.
The nut is provided with for controlling the inside groove that plug screw is installed and dismantled, and inside groove is hexahedron.
Sealing ring is applied mechanically on the purge cock body, one end of sealing ring contacts with nut.
The sealing ring is set to frustum, near nut one end with diameter greater than the diameter near purge cock body end portion.
The sealing ring is provided with the transition face of taper near the one end in purge cock body end portion.
The nut contacts side with sealing ring and is provided with concave groove for placing sealing ring
Beneficial outcomes of the present utility model：
This utility model stores up dirty groove can be to one storage of the impurity such as the iron filings of precipitation in machine oil, carbide, greasy filth offer
Place, prevents from being again sucked into oil duct, and the impurity in oil sump can be made to be more easy to be discharged cleaning, Er Qieke when machine oil is discharged
To mitigate weight.

Specific embodiment
A kind of purge cock on automobile oil pan, the purge cock includes purge cock body 1, purge cock nut 2
With the plug screw screw thread being located on purge cock body 1, described purge cock is arranged in the spiro pluging hole of fuel tank, described plug screw spiral shell
Stricture of vagina is with spiro pluging hole screw-internal thread fit and screws, and the end of described purge cock body 1 is provided with for storing the dirty groove 4 of dirty storage.
Used as preferred, it is inclined plane that dirty groove 4 is stored up in this utility model for bottom surface, the dirty groove of the storage that such setting makes
4 one end are higher than the other end, and the relatively low side of the dirty groove 4 of storage can be slipped to due to the impact of gravity when there is the dirty dirty groove 4 into storage,
The optimization to storing up the dirty space of groove 4 is realized, optimization the biggest is provided with mesh screen 5 on dirty groove 4 is stored up, and the area of mesh screen 5 is dirty less than storage
The area of groove 4, the mesh screen 5 is located at the relatively low side top in the dirty position of groove 4 of storage, and such setting can partly stop dirty in storage
The foul of groove 4 is taken out of by fluid, improves the dirty ability of storage.As preferred, the inwall of dirty groove 4 stored up in this utility model and is set
Have for the flat thin magnet of adsorbing metal impurity, can adsorb can be by the metal impurities of magnet adsorption to some.
Used as preferred, the section of nut 2 is polygon in this utility model, and the placement of convenient wrench prevents the nothing of nut 2
Spanner clamping position.
Used as preferred, nut 2 is provided with and installs inside groove 21 with dismounting, inside groove for controlling plug screw in this utility model
21 is hexahedron, not only facilitates and opens, while such setting is the increase in a kind of opening ways, it is possible to use different works
Tool is opened to plug screw, enhances replaceability.
As preferred, sealing ring 3, one end and the nut 2 of sealing ring 3 are applied mechanically in this utility model on purge cock body 1
Contact, sealing ring 3 is set to frustum, near the one end of nut 2 with diameter greater than the diameter near the end of purge cock body 1, so
Setting enhance the sealing of sealing ring 3 because sealing ring 3 can part enter in installing hole with plug screw so that itself with
Installing hole contact is more tight.
Used as preferred, sealing ring 3 is provided with the transition of taper near one end of the end of purge cock body 1 in this utility model
Face 31, such setting has certain taper, facilitates sealing ring 3 to enter in installing hole, and then can realize sealing effectiveness.
As preferred, projecting point is increased in the outside of nut 2 in this utility model, it is convenient to open for increasing friction.
Obviously, above-described embodiment is only intended to clearly illustrate example, and not to the restriction of embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description other multi-forms change or
Change.There is no need to be exhaustive to all of embodiment.And the obvious change thus extended out or
Among changing the protection domain created still in this utility model.
