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 utility model provides a kind of carburetor throttle angle lock mechanism, and structure is simple,
Use flexibly can automate the angle of damper, different working environments can make air door be respectively at full-gear,
Half-open position and full-shut position.Simultaneously after engine heat engine, the suction of breather valve declines, and this structure is also possible to prevent wind
Door revolution.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of carburetor throttle angle locking machine
Structure, including ontology and air door bracing wire are provided with air inlet on the ontology, and the air inlet is provided with air door, and the air door is solid
It is scheduled in shaft, the shaft rotation connection on the body, is provided with the driving air door towards closing in the shaft
The torsional spring of state, air door bracing wire one end are connected with breather valve, and when engine start, the air door bracing wire pulls the shaft
Rotation is additionally provided with limit plate in the shaft, is provided on the limit plate so that the air door is rotated towards full-gear
Location hole further includes the driving machine that the locating rod matched with the location hole and the driving locating rod are inserted into the location hole
Structure.Original state, air door are in close state, engine cold-start, pull air door to turn towards opening state by air door bracing wire
Dynamic, when reaching the angle of restriction, driving mechanism driving locating rod is inserted into positioning hole, the angle locking of air door is realized, by wind
Door is located in half-open angle, and after a period of time runs, engine temperature is increased, and driving mechanism drives the locating rod to leave
The location hole, air door continue to rotate under the action of bracing wire, and when reaching full-gear, driving mechanism is in driving locating rod insertion
Corresponding positioning hole maintains the full-gear of air door.When engine cutoff, driving mechanism driving locating rod leaves location hole,
Air door is restored to closed state under the action of torsional spring.Whole process fully achieves automation, is not necessarily to manual intervention.It is sending out simultaneously
After motivation 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 utility model are: original state, air door is in close state, and engine cold-start passes through wind
Door bracing wire pulls air door to rotate towards opening state, and when reaching the angle of restriction, driving mechanism driving locating rod is inserted into positioning
In hole, the angle locking of air door is realized, air door is located in half-open angle, after a period of time runs, engine temperature liter
Height, driving mechanism drive the locating rod to leave the location hole, and air door continues to rotate under the action of bracing wire, reach standard-sized sheet shape
When state, driving mechanism is inserted into corresponding positioning hole in driving locating rod, maintains the full-gear of air door.When engine cutoff,
Driving mechanism driving locating rod leaves location hole, and air door is restored to closed state under the action of torsional spring.Whole process is completely real
It now automates, is not necessarily to manual intervention.Simultaneously after engine heat engine, the suction of breather valve declines, due to the restriction of locating rod
Effect is also possible to prevent air door revolution.
