Abstract
The utility model relates to a spark plug lag sets up at the valve cage shroud and takes between the cylinder cap of spark plug, including the spark plug sleeve pipe, a spark plug sheathed tube tip is inserted and is established on the cylinder cap with the protection spark plug, and the other end and the butt joint of valve cage shroud, this spark plug sleeve pipe and cylinder cap are provided with the sealing washer on for clearance fit and fitting surface. The utility model provides a spark plug lag structure that sealing performance is better, can effectively avoid the valve cage in the engine working process in the leakage of machine oil.
Description
Technical field
This utility model belongs to technical field of automobile components, is specifically related to a kind of spark plug boots structure.
Background technology
Spark plug boots is the important safety parts of gas engine, and existing spark plug boots mainly uses spiral shell
Stricture of vagina seals, and when gas engine works, the machine oil in valve cage can be revealed, and spark plug is with high-voltage line even
Meet place and immersion oil, the as easy as rolling off a log high-voltage line cold run that causes occur, even damage spark plug and high-voltage line.
Utility model content
Technical problem to be solved in the utility model is can for a kind of sealing property of above-mentioned prior art offer
The spark plug boots structure leaned on, prevents lubricating oil leakage.
The technical scheme in the invention for solving the above technical problem is: a kind of spark plug boots, is arranged on
Between the cylinder cap of valve cage cover cap and band spark plug, including ignition plug sleeve, the one end of described ignition plug sleeve
Dividing and be plugged on cylinder cap to protect spark plug, the other end docks with valve cage cover cap, this ignition plug sleeve and cylinder cap
For being provided with sealing ring on matched in clearance and cooperation face.
Specifically, described ignition plug sleeve periphery forms the positive stop lug boss offseted with cylinder cap, outside ignition plug sleeve
Separately it is arranged with pressing plate, described pressing plate and aforementioned positive stop lug boss compression fit week.
Preferably, one end that described ignition plug sleeve coordinates with valve cage cover cap is provided with seal cover board, described close
Capping plate is provided with sealing ring with coordinating of described valve cage cover cap on face, improve ignition plug sleeve and valve cage cover
Sealing between lid.
Compared with prior art, the utility model has the advantage of: provide a kind of more preferable spark of sealing property
Plug protecting jacket structure, can be prevented effectively from the leakage of valve cage inner engine oil in engine working process.
Accompanying drawing explanation
Fig. 1 is the structural representation of spark plug boots in this utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
As it is shown in figure 1, the spark plug boots in the present embodiment, it is arranged on valve cage cover cap 1 and band spark plug
Between the cylinder cap 8 of 7, including ignition plug sleeve 4, one end part of ignition plug sleeve 4 is plugged on cylinder cap 8
Filling in protection spark 7, the other end docks with valve cage cover cap 1, and this ignition plug sleeve 4 is gap with cylinder cap 8
Coordinate and be provided with sealing ring 6 on cooperation face.
Ignition plug sleeve 4 periphery forms the positive stop lug boss 4.1 offseted with cylinder cap 8, ignition plug sleeve 4 periphery
Separately it is arranged with pressing plate 5, pressing plate 5 and aforementioned positive stop lug boss 4.1 compression fit.
One end that ignition plug sleeve 4 coordinates with valve cage cover cap 1 is provided with seal cover board 3, seal cover board 3 with
It is provided with sealing ring 2 on the cooperation face of valve cage cover cap 1, and then improves ignition plug sleeve 4 and valve cage cover cap
Sealing between 1.
The spark plug boots sealing property of said structure is the most reliable, can be effective in engine working process
Avoid the leakage of valve cage inner engine oil.
In addition to the implementation, this utility model also includes other embodiments, all employing equivalents or
The technical scheme that equivalence substitute mode is formed, within all should falling into this utility model scope of the claims.
