Description
Technical field
The present invention relates to technical field of engines, more particularly to a kind of new work engine oil rule.
Background technology
Oil level gauge of engine is a kind of common parts, for determining engine crankcase inside oil level.
In the prior art, conventional oil rule is divided into chi core and chi set, and chi core inserts chi set, footpath by the jack that chi covers
To the elastic seal ring on compression ruler core.Elastic seal ring is usually rubber, and its elastic force produces friction on chi set surface
Power, to fasten chi core, prevents chi core from not inadvertently departing from chi set.But due to the easy problem of aging of rubber, elastic seal ring
Meeting is aging with rubber, and gradually loses locking effect.
Secondly, increasingly strict with automobile emission regulation, vehicular engine has generally employed enclosed and has forced crankcase
Oil gas imperfect combustion in crankcase, is introduced inlet manifold by ventilating system, returns to combustion chambers burn, to reduce discharge, is carried
Economy high.However, because the northern area of China winter temperature is often less than -40 DEG C, derived deep fat gas, is entering from crankcase
At gas manifold river conjunction, because air gathers, it is easily caused and freeze herein and block crankcase bleed pipe, causes engine crankshaft
Oil gas cannot be discharged in time in case, and long-play can cause engine introversion axle box hypertonia, and excessive pressure difference will cause
Engine oil seal oil leak, or even come off, have a strong impact on the safe operation of engine.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of new work engine oil rule, to provide
The locking scheme of oil rule of permanent stabilization and reliable crank case pressure control scheme, so that it is guaranteed that the safety fortune of engine
OK.
The present invention is achieved by the following technical solutions：
A kind of new work engine oil rule, including handle, lock, oil rule core and guide pipe,
Lock is cased with the handle end, the lower end of the lock left and right sides respectively opens up a locking slot, the guiding
Pipe top each side sets a short pin, and two short pins are engaged the self-locking for realizing guide pipe and lock with corresponding locking slot；
The handle bottom center is provided with a vertical blind hole, is fixed with oil rule core in blind hole, the oil rule core from
On down sequentially pass through the cavity in lock and be oriented to tube hub, is provided with ball valve above the oil rule core in the blind hole
With deflation valve spring, ball valve is pressed in oil rule core upper surface, seals the centre bore of oil rule core by the deflation valve spring；Institute
State handle side and be provided with the passage connected with blind hole top, in its natural state, the ball valve is located at passage lower section,
When air pressure is too high in oil rule core centre bore, air pressure overcomes the elastic force of the deflation valve spring in oil rule core centre bore, to
Upper compression deflation valve spring, makes the ball valve move up opening passage so that in the passage and the oil rule core
The connection of heart hole upper end is deflated, and after oil rule core centre bore internal pressure declines, ball valve is taken a seat again, in sealing oil rule core
Heart hole；
Baffle plate is provided with the cavity of the lock, baffle plate is pressed in the guide pipe top by the lower pressing spring above baffle plate
Face；
The locking slot is in inverted L-shaped and end is provided with groove, and the short pin of the guide pipe upper end is inserted upwardly into corresponding lock
Tight groove is simultaneously entered in the groove of locking slot end by horizontally rotating handle to short pin, then release handle, will by lower pressing spring
Short pin on guide pipe is pressed in the groove of locking slot end, realizes the self-locking of guide pipe and lock.
As the preferred embodiment of above-mentioned technical proposal, the baffle plate lower surface be oriented to the seal of tube at be provided with annular
Groove, sealing ring is fixed with the annular groove.
Used as the preferred embodiment of above-mentioned technical proposal, the locking slot of the lock left and right sides is with the lock
The heart is centrosymmetric setting.
Used as the preferred embodiment of above-mentioned technical proposal, the cavity inner wall stage casing of the lock is provided with annular spacing groove,
The annular spacing groove is used to install spacing back-up ring, and the spacing back-up ring is located under the baffle plate for limiting baffle plate
Position.
Used as the preferred embodiment of above-mentioned technical proposal, the lower pressing spring is dish-shaped-spring stack.
