Description
Technical field
The present invention relates to a kind of carburetors, more particularly, to a kind of carburetor throttle angle lock mechanism.
Background technique
Carburetor is the machinery that mixes with air a certain proportion of gasoline under the vacuum action that engine operation generates
Device.A kind of mechanical device of the carburetor as precision, it utilizes the atomization of the kinetic energy realization gasoline of sucking air stream.It is right
The important function of engine can be referred to as " heart " of engine.Carburetor can be according to the different working condition need of engine
It asks, automatic mixing goes out corresponding concentration, exports the gaseous mixture measured accordingly.Currently, general carburetor is at work, air door
State is all two states, i.e. full trrottle state and air door full-shut position, and when engine is in just starting, needs hand
The dynamic state for pulling air door bracing wire to open damper, such practical utilization process is set more troublesome, angle of air door
Adjust have limitation, therefore we it is necessary to be improved.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of carburetor throttle angle lock mechanism, and structure is simple, uses
Flexibly, the angle that can automate damper can make air door be respectively at full-gear, half-open in different working environments
State and full-shut position.Simultaneously after engine heat engine, the suction of breather valve declines, and this structure is also possible to prevent air door and returns
Turn.
The technical solution adopted by the present invention to solve the technical problems is: a kind of carburetor throttle angle lock mechanism, packet
Ontology and air door bracing wire are included, air inlet is provided on the ontology, the air inlet is provided with air door, and the air door, which is fixed on, to be turned
On axis, the shaft rotation connection on the body, is provided with the driving air door towards closed state in the shaft
Torsional spring, air door bracing wire one end are connected with breather valve, and when engine start, the air door bracing wire pulls the shaft rotation,
So that the air door is rotated towards full-gear, it is additionally provided with limit plate in the shaft, positioning is provided on the limit plate
Hole further includes the driving mechanism that the locating rod matched with the location hole and the driving locating rod are inserted into the location hole.
Original state, air door are in close state, engine cold-start, pull air door to rotate towards opening state by air door bracing wire,
When reaching the angle limited, driving mechanism driving locating rod is inserted into positioning hole, realizes the angle locking of air door, air door is determined
Position is in half-open angle, and after a period of time runs, engine temperature is increased, and it is described that driving mechanism drives the locating rod to leave
Location hole, air door continue to rotate under the action of bracing wire, and when reaching full-gear, driving mechanism is corresponding in driving locating rod insertion
Positioning hole, maintain the full-gear of air door.When engine cutoff, driving mechanism driving locating rod leaves location hole, air door
Closed state is restored under the action of torsional spring.Whole process fully achieves automation, is not necessarily to manual intervention.Simultaneously in engine
After heat engine, the suction of breather valve declines, and due to the restriction effect of locating rod, is also possible to prevent air door revolution.
In above-mentioned technical proposal, it is preferred that the driving mechanism is solenoid valve, and the locating rod is on the solenoid valve
Valve rod.
In above-mentioned technical proposal, it is preferred that there are two the solenoid valves.In this way, under different operating conditions, it can
The locking of the different angle of air door is realized to be inserted into location hole by different locating rods.The electromagnetic valve structure of selection is small, is convenient for
Installation.
In above-mentioned technical proposal, it is preferred that be arranged with spring on the valve rod, the spring drives the valve rod to hold out against
The limit plate.
In above-mentioned technical proposal, it is preferred that the solenoid valve is located at the lower section of the limit plate.In this way, solenoid valve
Installation is easily facilitated, overall structure is simplified.
In above-mentioned technical proposal, it is preferred that there are three the location holes.In this way, under different operating conditions, it can
Realize that air door is in fully closed, half-open and standard-sized sheet three states to be inserted into different location holes by different locating rods.
The beneficial effects of the present invention are: original state, air door is in close state, and engine cold-start is drawn by air door
Line pulls air door to rotate towards opening state, and when reaching the angle of restriction, driving mechanism driving locating rod is inserted into positioning hole,
Air door is located in half-open angle by the angle locking for realizing air door, and after a period of time runs, engine temperature is increased, and is driven
Motivation structure drives the locating rod to leave the location hole, and air door continues to rotate under the action of bracing wire, when reaching full-gear,
Driving mechanism is inserted into corresponding positioning hole in driving locating rod, maintains the full-gear of air door.When engine cutoff, driving machine
Structure driving locating rod leaves location hole, and air door is restored to closed state under the action of torsional spring.Whole process fully achieves automatically
Change, is not necessarily to manual intervention.Simultaneously after engine heat engine, the suction of breather valve declines, due to the restriction effect of locating rod,
It can prevent air door from turning round.
