Abstract
The utility model relates to a carburetor which can close a choke valve automatically and comprises the choke valve and an air throttle, wherein a choke valve regulating arm and an air throttle regulating arm are respectively fixed on the upper ends of a choke valve shaft and an air throttle shaft, a connecting bar is connected between the choke valve regulating arm and the air throttle regulating arm and takes an arc shape with a section of connecting bar which takes the connecting end of the air throttle regulating arm as an initial point. A petrol engine which is provided with the carburetor does not need a special operation that the choke valve is closed when in starting, which enables the starting operation of the petrol engine to be more convenient.
Description
Technical field
The utility model relates to a kind of Carburetor that is installed on the general gasoline engines.
Background technique
The Carburetor that is complementary with petrol engine is installed on the general gasoline engines, have chock plate and closure on the Carburetor, chock plate and closure are installed on the Carburetor body by Air strangler spindle and throttle plate pin respectively, can rotate with respect to the Carburetor body, rotate thereby drive chock plate and closure, to realize the open and close of carburetor air mouth and oil-feed (mist) mouth.Air strangler spindle and throttle plate pin upper end are fixed with chock plate regulating arm and throttle adjustment arm respectively, chock plate regulating arm and throttle adjustment arm all are positioned at the Carburetor top, when it is rotated, just can drive chock plate and closure rotation by Air strangler spindle and throttle plate pin.
Chock plate regulating arm and throttle adjustment arm on the existing Carburetor are to be installed in the Carburetor top independently of each other, do not have any annexation between the two.Before gasoline engine starting, chock plate and closure all are in opening state, in order to guarantee that petrol engine can normally start when the cold machine state, before gasoline engine starting, must earlier chock plate be closed, so existing petrol engine is when starting, an act of operation that chock plate is closed must be arranged, and this brings certain trouble for the start-up operation of petrol engine.
The model utility content
The purpose of this utility model provides a kind of Carburetor that can close chock plate automatically, need not close the operation of chock plate when starting petrol engine specially.
The Carburetor that can close chock plate automatically described in the utility model, comprise chock plate, closure, it is installed on the Carburetor body by Air strangler spindle and throttle plate pin respectively, can rotate with respect to the Carburetor body, Air strangler spindle and throttle plate pin upper end are fixed with chock plate regulating arm and throttle adjustment arm respectively, be connected with connecting rod between chock plate regulating arm and the throttle adjustment arm, the connecting rod two ends are hooked on chock plate regulating arm and the throttle adjustment arm by the through hole that is opened on chock plate regulating arm and the throttle adjustment arm, with with throttle adjustment arm connecting end be that one section connecting rod of starting point is circular-arc, this plane, arc section place of connecting rod is vertical with throttle plate pin, and it is consistent apart from the distance of throttle plate pin axis to be used for the through hole of hook connecting rod on the radius of this arc section and the throttle adjustment arm.
When starting petrol engine, being used to regulate the speed regulating mechanism (it is connected with the throttle adjustment arm) of controlling closure folding degree on the petrol engine will be with closed throttle.Closure from opening state to the closed condition rotation process, originally, the throttle adjustment arm rotates and can not promote connecting rod along the arc section of connecting rod, connecting rod can not move in this process; And when the throttle adjustment arm when connecting rod goes to connecting rod arc section terminal, at this moment, the throttle adjustment arm is rotated further again, and then the throttle adjustment arm will promote connecting rod and move, then make connecting rod pass through the chock plate regulating arm and drive the chock plate rotation, thereby chock plate is closed.
Connecting rod and throttle adjustment arm connecting end have an arc section, this plane, arc section place of connecting rod is vertical with throttle plate pin, and the through hole that is used for the hook connecting rod on the radius of this arc section and the throttle adjustment arm is consistent apart from the distance of throttle plate pin axis, can make the throttle adjustment arm can not promote connecting rod when originally rotating moves, thereby when petrol engine (the return unlatching of chock plate this moment) in running, speed regulating mechanism on the petrol engine is when regulating control closure rotation folding, the throttle adjustment arm just can not exert an influence to the state of connecting rod, just can the folding degree of chock plate not exerted an influence yet.
The pairing central angle of the arc section of described connecting rod can guarantee like this before closure is closed fully that less than 90 ° chock plate is in closing closed procedure.
The connecting rod two ends are hook solid, make connecting rod easily hold-down hook hang on chock plate regulating arm and the throttle adjustment arm.
The utility model is equipped with the connecting rod with arc section between chock plate regulating arm and throttle adjustment arm, when starting petrol engine, can automatically chock plate be closed, and in the petrol engine running, can the control of closure folding degree not exerted an influence, for the start-up operation of petrol engine has reduced the action of closing chock plate, thereby make the start-up operation of petrol engine convenient.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is the schematic top plan view that can close the Carburetor of chock plate automatically described in the utility model;
Fig. 2 is the plan view of connecting rod;
Fig. 3 is the plan view of connecting rod shown in Figure 2.
Embodiment
As shown in Figure 1, this Carburetor that can cut out chock plate automatically comprises chock plate, closure, and chock plate and closure are installed on the Carburetor body 1 by Air strangler spindle 5 and throttle plate pin 2 respectively, can rotate with respect to Carburetor body 1.Air strangler spindle 5 and throttle plate pin 2 upper ends are fixed with chock plate regulating arm 6 and throttle adjustment arm 3 respectively, be connected with connecting rod 4 between chock plate regulating arm 6 and the throttle adjustment arm 3, connecting rod 4 two ends are hooked on chock plate regulating arm 6 and the throttle adjustment arm 3 by the through hole that is opened on chock plate regulating arm 6 and the throttle adjustment arm 3.As shown in Figures 2 and 3, with with throttle adjustment arm 3 connecting ends be that one section connecting rod of starting point is circular-arc, these arc section 7 pairing central angles of connecting rod 4 are less than 90 °, this plane, arc section 7 place is vertical with throttle plate pin 2, and the through hole that is used for hook connecting rod 4 on the radius of this arc section 7 and the throttle adjustment arm 3 is consistent apart from the distance of throttle plate pin 2 axis, connecting rod 4 two ends are hook solid, can make connecting rod 4 easily hold-down hook hang on chock plate regulating arm 6 and the throttle adjustment arm 3.
