Abstract
The utility model provides a OCV valve bolt clamping structure, structure and its edge that the mounting hole design is three sharp zigzag connections on three circular arcs make its marginal maximum gauge be less than the pitch of bolt through setting up the oblique angle to when making the set assembling of OCV valve, need not bolt fastening cover and bolt pad, the cost is reduced has retrencied installation procedure, makes on more convenient, more practical and its overall structure of installation simplyr.
Description
Technical field
This utility model relates to engine oil path and controls parts OCV valve, is specifically related to a kind of OCV valve bolt card locking structure.
Technical background
Existing OCV valve, when being assembled to installing hole, there is following shortcoming in bolt:
1) bolt fixed cover and two parts of bolting pad need to be increased；
2) bolt fixed cover needs die sinking to make, and installation procedure is complicated and increases cost；
3) when spiral shell pad is expressed to installing hole, easily cause shell position of mounting hole to deform, make OCV valve install impacted.
Summary of the invention
For problems of the prior art, this utility model provides a kind of OCV valve bolt card locking structure, installing hole is designed as structure that three-arc three straight line is cross-linked and its edge makes the maximum gauge pitch less than bolt at its edge by arranging oblique angle, so that during the assembling of OCV valve assembly, without bolt fixed cover and bolting pad, reduce cost, simplified installation procedure so that installation process is more convenient, more practical and simpler in its overall structure.
For solving above-mentioned technical problem, the technical solution adopted in the utility model: a kind of OCV valve bolt card locking structure, including shell, bolt, shell is provided with installing hole, bolt is provided with external screw thread, installing hole is cross-linked to form by three-arc three straight line and the minimum diameter of this installing hole and the female thread that can match with external screw thread equivalently-sized, and the maximum gauge at installing hole edge is less than the pitch of bolt, and bolt is screwed into installing hole.
Preferred as such scheme, installing hole edge is provided with oblique angle.
The beneficial effects of the utility model are: installing hole is designed as structure that three-arc three straight line is cross-linked and its edge makes the maximum gauge pitch less than bolt at its edge by arranging oblique angle, so that during the assembling of OCV valve assembly, without bolt fixed cover and bolting pad, reduce cost, simplify installation procedure, making installation process more convenient, more practical and simpler in its overall structure, this programme Assembly part is less, assembles more convenient and integral installation formula formula is the most reasonable.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model；
Fig. 2 is the top view (bolt is not drawn into) of Fig. 1.
In figure: 1, shell, 2, bolt, 3, installing hole.
Detailed description of the invention
In conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of OCV valve bolt card locking structure, including shell 1, bolt 2, shell 1 is provided with installing hole 3, bolt 2 is provided with external screw thread, installing hole 3 is cross-linked to form by three-arc three straight line and the minimum diameter of this installing hole and the female thread that can match with external screw thread equivalently-sized, the maximum gauge at installing hole 3 edge is less than the pitch of bolt 2, bolt is screwed into installing hole 3 by the principle utilizing external screw thread to match with female thread, in this programme, installing hole 3 edge is provided with oblique angle, so that the thickness at installing hole 3 edge is less than the pitch of bolt 2.
The above; it is only preferred embodiment of the present utility model; not in order to limit this utility model, every any trickle amendment, equivalent and improvement made above example according to technical spirit of the present utility model, within should be included in the protection domain of technical solutions of the utility model.
