Description
Technical field
The utility model is related to a kind of cylinder head cover Pcv valve installation structures, belong to cylinder head cover technical field.
Background technology
In gasoline engine with supercharger, gasoline engine naturally aspirated engine research and development manufacturing process, for the PCV on cylinder head cover
Valve assembles, and typically Pcv valve is located on cylinder head cover using the modes such as interference fit or threaded connection, the assembly method
Pcv valve can be dismantled arbitrarily, and the situation that PCV leakages occurs in certain probability is ressembled after dismantling.
Invention content
Shortcoming in for the above-mentioned prior art, the utility model are intended to provide a kind of cylinder head cover Pcv valve installation knot
Structure makes Pcv valve be fitted close with cylinder head cover, and Pcv valve is prevented arbitrarily to dismantle, and then avoids Pcv valve through lack of standardization
The caused leakage situation of dismounting, installation.
To achieve the goals above, the technical solution of the utility model：A kind of cylinder head cover Pcv valve installation structure comprising
Cylinder cap cover body and the mounting base for being used to install Pcv valve thereon, it is characterised in that：The mounting base includes to be shaped in institute
State the pedestal on cylinder cap cover body, on the pedestal have the mounting post with axially extending bore and with the matched buckle closure of the mounting post,
The Pcv valve is through at the centre bore of the buckle closure, and the positioning to the Pcv valve is realized by the mounting post, buckle closure, wherein
The mounting post free end has the ladder shaft part to match with the buckle closure, and is circumferentially provided in the ladder shaft part outer wall and is in
The stuck point of wedge structure, and be provided with and can coordinate with the stuck point and for being limited to the stuck point in the buckle closure side
Limit hole.
Further, the stuck point quantity at least two is uniformly arranged on the ladder shaft part circumferential position, and
The stuck point is integrally formed with the pedestal.
Further, the axially extending bore in the mounting post is poroid in interior multi-diameter shaft, with buckle closure cooperation realization pair
The axial limiting of the Pcv valve.
The beneficial effects of the utility model：Coordinated by mounting post and buckle closure, by the stuck point and buckle closure in mounting post
Limit hole forms non-collapsible stuck so that Pcv valve is fitted close with cylinder head cover, and PCV valves is prevented arbitrarily to dismantle, and then is kept away
Pcv valve is exempted from through the caused leakage situation of dismounting lack of standardization, installation.
Description of the drawings
Fig. 1 is the structure chart of the utility model；
Fig. 2 is the sectional view of cylinder head cover Pcv valve installation structure in Fig. 1；
Fig. 3 is the decomposition diagram of Fig. 2.
Specific implementation mode
The utility model is further described with reference to specific embodiment and attached drawing.
One kind cylinder head cover Pcv valve installation structure as described in Fig. 1-Fig. 3 comprising cylinder cap cover body 1 and thereon for installing
The mounting base of Pcv valve 2, the mounting base include the pedestal 10 being shaped on cylinder cap cover body 1, have band on the pedestal 10
The mounting post 11 of axially extending bore and with the 11 matched buckle closure 14 of mounting post, Pcv valve 2 is through at the centre bore of buckle closure 14, and by
Mounting post 11, buckle closure 14 realize the positioning to Pcv valve 2, wherein 11 free end of mounting post has the rank to match with buckle closure 14
Terraced shaft part 13, and it is circumferentially provided with the stuck point 12 of wedge shaped structure in 13 outer wall of ladder shaft part, and be arranged in 14 side of buckle closure
There is the limit hole 15 that can coordinate with stuck point 12 and be used to limit the stuck point 12.
The positioning to Pcv valve 2 is realized by 10 medial surface of buckle closure, and the axially extending bore in mounting post 11 is in interior ladder axis hole
Shape coordinates the axial limiting realized to Pcv valve 2, to ensure 2 stable position of Pcv valve on cylinder cap cover body 1 with buckle closure 14.
With stuck point 12 and limit hole 15, realize that the locking between buckle closure 14 and mounting post 11 coordinates, and the buckle closure 14
Non-dismountable between mounting post 11, except the stuck point 12 on non-damaging buckle closure 14 or mounting post 11, in other words Pcv valve 2 can not
Arbitrarily dismounting, pull-off, unless carrying out destructive dismounting.Specifically, 12 quantity at least two of stuck point, for example, two, three, four
It is a etc., it is uniformly arranged on 13 circumferential position of ladder shaft part, and the stuck point 12 is integrally formed with pedestal 10.
The technical solution provided above the utility model embodiment is described in detail, used herein specifically
A example is expounded the principle and embodiment of the utility model embodiment, and the explanation of above example is only applicable to help
Assistant solves the principle of the utility model embodiment；Meanwhile for those of ordinary skill in the art, implementing according to the utility model
Example, the there will be changes in specific implementation mode and application range, in conclusion the content of the present specification should not be construed as
Limitations of the present invention.
