Description
Technical field
The utility model relates to a kind of carburetors, more particularly, to a kind of carburetor throttle Anti-jamming structure.
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, being commonly equipped with solenoid valve damper angle
Carburetor during operation, be all by the locating rod socket joint on solenoid valve on limit plate come the angle of fixed throttle.
Such setting, it may appear that the excessive situation of the frictional force between location hole in locating rod and limit plate causes to work as solenoid valve
Locating rod is unable to retracted downward when receiving signal, and due effect is not achieved.Due to the presence of problem above, we have must
This is improved.
Summary of the invention
In view of the deficiencies of the prior art, the utility model provides a kind of carburetor throttle Anti-jamming structure, and structure is simple, can
To ensure that the valve rod of solenoid valve will not be stuck on limit plate, carburetor throttle regulating system can run well.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of carburetor throttle Anti-jamming structure,
Including ontology and air door bracing wire, air door is provided on the ontology, the air door is fixed in shaft, the shaft rotation connection
On the body, the torsional spring for driving the air door towards closed state, air door bracing wire one end are provided in the shaft
It is connected with breather valve, when engine start, the air door bracing wire pulls the shaft rotation, so that the air door is towards standard-sized sheet shape
State rotation, the shaft are equipped with limit plate, are provided with location hole on the limit plate, further include matching with the location hole
Locating rod and drive the locating rod to be inserted into the driving mechanism of the location hole, be provided with tension spring in the air door bracing wire, institute
Stating tension spring drives the air door to rotate towards full-gear, and the elastic force of the tension spring is greater than the torsion of the torsional spring.In this way,
The elastic force and torsional spring opposite direction active force of tension spring, can prevent locating rod stuck on limit plate.
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.The electromagnetic valve structure of selection is small, is easily installed.
The beneficial effects of the utility model are: being provided with tension spring in the air door bracing wire, the tension spring drives the air door
It is rotated towards full-gear, the elastic force of the tension spring is greater than the torsion of the torsional spring.In this way, the elastic force of tension spring and torsional spring are anti-
Direction active force can prevent locating rod stuck on limit plate, and carburetor throttle regulating system can run well.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the total schematic diagram of structure of the utility model.
Fig. 2 is the structure top view of the utility model.
In figure, 1. ontologies, 2. air door bracing wires, 3. tension springs, 4. torsional springs, 5. shafts, 6. limit plates, 7. valve rods, 8. solenoid valves,
9. air door, 10. location holes.
Specific embodiment
In Fig. 1-2, a kind of carburetor throttle Anti-jamming structure, including ontology 1 and air door bracing wire 2,1 is set on the ontology
It is equipped with air door 9, the air door 9 is fixed in shaft 5, and the shaft 5 is rotatably connected on the ontology 1, is set in the shaft 5
It is equipped with the torsional spring 4 for driving the air door 9 towards closed state, described 2 one end of air door bracing wire is connected with breather valve, engine start
When, the air door bracing wire 2 pulls the shaft 5 to rotate, so that the air door 9 is rotated towards full-gear, sets in the shaft 5
There is limit plate 6, be provided with location hole 10 on the limit plate 6, further includes the valve rod 7 matched with the location hole 10 and driving
The valve rod 7 is inserted into the solenoid valve 8 of the location hole 10, and tension spring 3 is provided in the air door bracing wire 2, and the tension spring 3 drives institute
Air door 9 is stated to rotate towards full-gear, the elastic force of the tension spring 3 is greater than the torsion of the torsional spring 4, the elastic force of the tension spring 3 with
4 opposite direction active force of torsional spring, can prevent valve rod 7 stuck on limit plate 6, carburetor throttle regulating system can be transported normally
Turn.
