Description
Technical field
This utility model relates to general small-size gasoline engine technical field, particularly to little between 35mL to 50mL of discharge capacity
The easy starter of type gasoline engine.
Background technology
General small-size gasoline engine is made up of cylinder body, crankcase combination, moving parts, magneto, starter, spark plug etc.,
Starting of gasoline engine needs could normally be worked by the effect of external force, drives moving parts to revolve when starting by tractive starter
Turning, and then drive the piston up-down in moving parts compressed mixed gas, after ignition by magneto, gasoline engine runs well.
In starting process, owing to piston produces bigger resistance when pumping, operator during traditional startup, is needed to use
Large force quick tractive starter, could start machine, and easily the starting principle of starter is, starting up gasoline engine needs bigger
Moment of torsion, first the whole flat spring of process power stores the moment of torsion of driving wheel, then moment of torsion outburst is driven and starts thumb wheel and revolve rapidly
Turning, thus drive gasoline starting, strong owing to starting explosive force, the advantage extremely users such as comfortableness is good favor, but put down power
The fatigue strength of spring requires the harshest, owing to the fatigue life of the easiest starter is poor, becomes the bottleneck of easy starter development,
Therefore a kind of easy starter guaranteeing that power flat spring anti-fatigue ability is strong, the flat spring of power is not easy locking it is badly in need of.
Summary of the invention
In view of this, this utility model purpose is to provide and a kind of starts the easy starter that thumb wheel is eccentric structure, by right
Start the improvement of thumb wheel, and then the Curvature varying that the flat spring of power changing easy starter is when starting up gasoline engine, thus improve dynamic
The fatigue life of the flat spring of power, make the more robust of easy starter；Can strengthen the installing space of the flat spring of power, anti-stopping power is put down simultaneously
The locking phenomenon of spring.
The technical scheme that this utility model is taked is as follows:
A kind of easily starter, including starter housing, the flat spring of return being hooked in starter housing, driving wheel, successively
Being arranged on the pad within driving wheel, the flat spring of power, start thumb wheel, and one ends wound is on driving wheel, the other end is from starter
Housing passes with starter hands the stay cord being connected, it is characterised in that: described driving wheel is provided with driving wheel groove one, described
Dynamic thumb wheel is provided with starting thumb wheel groove, and the two ends of the flat spring of described power are hooked on driving wheel groove one respectively and starting thumb wheel is recessed
On groove；Described starting thumb wheel is eccentric structure, causes the inner side patch in the outside starting thumb wheel groove and power flat spring initiating terminal
Tightly, the gap of the opposite side and the flat spring of power that simultaneously start thumb wheel groove becomes big.
The one side of described starting thumb wheel is provided with starting pusher dog, and another side is provided with circular bosses, is provided with interior logical in circular bosses
Hole, described circular bosses is the most concentric with inner via hole.
Being provided with starting thumb wheel groove at the outside cylinder of described circular bosses, it is recessed that starting thumb wheel is inserted in described power flat spring one end
Groove, other parts are wrapped in the outside cylinder of circular bosses.
The beneficial effects of the utility model are, starting up gasoline engine needs bigger moment of torsion, and the whole flat spring of process power is first
Store the moment of torsion of driving wheel, then drive starting thumb wheel to rotate rapidly moment of torsion outburst, the therefore fatigue strength of spring flat to power
Require the harshest.This utility model provides a kind of eccentric structure starting thumb wheel, i.e. starts the circular bosses center of circle and the circle of thumb wheel
When the boss inner via hole center of circle is not the same center of circle, cause the inner side patch in the outside starting thumb wheel groove and power flat spring initiating terminal
Tightly, the Curvature varying after power flat spring stress can be changed, improve the fatigue life of the flat spring of power, improve the reliable durable of starter
Property；The flat spring of power is arranged in the middle of driving wheel and circular bosses, after using the eccentric structure starting thumb wheel, starts thumb wheel groove
Opposite side becomes big with the gap of the flat spring of power, increases the installing space of the flat spring of power, brings after preventing the quick tractive of starter
The locking phenomenon of the flat spring of power.
