Positioning accuracy when gas manifold is installed.
Invention content
The purpose of this utility model is to provide a kind of New positioning mechanisms, it is intended to solve in the prior art how to protect
Under the premise of demonstrate,proving quality, reduces cost and make the more accurate technical problem of installation of inlet manifold.
To achieve the above object, the utility model use a kind of detent mechanism, the detent mechanism include be set into
It positioning convex platform on gas manifold mounting surface and is set on cylinder head mounting surface and location hole corresponding with positioning convex platform.
Wherein, the positioning convex platform includes the first positioning convex platform and the second positioning convex platform, first positioning convex platform and the
Two positioning convex platforms are symmetrically disposed on inlet manifold mounting surface,
Wherein, the location hole includes two, is symmetrically disposed on cylinder head mounting surface,
Wherein, first positioning convex platform is " ten " font, and second positioning convex platform is " I " font,
Wherein, four ends at the top of first positioning convex platform are equipped with arc-shaped transition section, the second positioning convex platform top
Both ends be equipped with arc-shaped transition section,
Wherein, the positioning convex platform is integrally formed with inlet manifold,
A kind of detent mechanism of the utility model, by the mutual cooperation of the positioning convex platform and location hole, to realize
While additionally need not increase additional device, keep each branch pipe gas outlet of inlet manifold and the cylinder-head port air inlet accurate
Contraposition connection.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, other drawings may also be obtained based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model detent mechanism；
Fig. 2 is the scheme of installation of the positioning convex platform of the utility model detent mechanism；
Fig. 3 is the enlarged drawing of the first positioning convex platform of the utility model detent mechanism；
Specific implementation mode
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
In the description of the present invention, it should be understood that term " length ", " width ", "upper", "lower", " preceding ",
The orientation or positional relationship of the instructions such as " rear ", "left", "right", "vertical", "horizontal", "top", "bottom" "inner", "outside" is based on attached
Orientation or positional relationship shown in figure, is merely for convenience of describing the present invention and simplifying the description, rather than indicates or imply
Signified device or element must have a particular orientation, with specific azimuth configuration and operation, therefore should not be understood as to this
The limitation of utility model.In addition, the meaning of " plurality " is two or more in the description of the present invention, unless separately
There is clearly specific restriction.
It please refers to Fig.1, Fig. 2 and Fig. 3, the detent mechanism 100 include the convex being set on inlet manifold mounting surface
It platform 10 and is set on cylinder head mounting surface and location hole corresponding with positioning convex platform 10 11.
In the present embodiment, the positioning convex platform 10 is inserted into corresponding location hole 11, to realize inlet manifold
Gas outlet and cylinder-head port air inlet mutual contraposition, prevent gas port from shifting, then again by bolt pass through set
The mounting hole being placed on inlet manifold mounting surface carries out installation with the registration holes of cylinder-head port air inlet mounting surface and is fixedly connected.
Further, the positioning convex platform 10 include the first positioning convex platform 101 and the second positioning convex platform 102, described first
Positioning convex platform 101 and the second positioning convex platform 102 are symmetrically disposed on inlet manifold mounting surface,
Further, the location hole 11 includes two, is symmetrically disposed on cylinder head mounting surface,
In the present embodiment, the positioning convex platform 10 and with its corresponding to location hole 11 be disposed as two be in order to
Prevent the gas outlet of cylinder-head port air inlet and inlet manifold along mounting surface horizontal sliding.
Further, first positioning convex platform 101 is " ten " font, and second positioning convex platform 102 is " I " font,
In the present embodiment, when inlet manifold is installed, first positioning convex platform 101 is first inserted into corresponding positioning
Hole 11, then second positioning convex platform 102 be inserted into corresponding location hole 11, first positioning convex platform 101 and second
It is for convenience when positioning insertion, if vertical side that positioning convex platform 102, which is respectively set to " ten " font and the purpose of " I " font,
To there are deviations, can be adjusted by second positioning convex platform 102 of " I " font.
Further, four ends at first positioning convex platform, 101 top are equipped with arc-shaped transition section 12, second positioning
The both ends at 102 top of boss are equipped with arc-shaped transition section 12,
In the present embodiment, the effect of the arc-shaped transition section 12 is the positioning in order to when inlet manifold is installed
In location hole 11 corresponding to the more convenient insertion of boss 10, because the positioning convex platform 10 is in 12 position of arc-shaped transition section
Width be less than location hole 11 diameter, so when vertical direction position occur deviation when, inlet manifold can be in a certain range
It is interior laterally to be finely tuned along mounting surface, to make positioning convex platform 10 be aligned with corresponding location hole 11.
Further, the positioning convex platform 10 is integrally formed with inlet manifold,
In the present embodiment, the positioning convex platform 10 is using integrated form plastics positioning convex platform 10, the positioning convex platform 10
It is integral type with inlet manifold, directly uses injection molding, without additionally uses positioning pin, installation cost to reduce, position simultaneously
Boss 10 and air inlet discrimination can have a simple advantage that makes together by mold injection molding, the positioning convex platform 10 with into
Gas manifold is installed together, and positioning pin installation procedure is saved compared to using positioning pin, has the simple advantage of assembly.
Above disclosed is only a kind of the utility model preferred embodiment, cannot limit this practicality with this certainly
