Abstract
The invention relates to a handle starting device of the internal combustion engine. The invention comprises a starting axle, a ratchet wheel, a ratchet pawl, a ratchet pawl pin, a casing body, a shifting fork, a clutch axle and a spring. One end of the clutch axle is connected with the starting axle in a cross way, and the other end is connected with the handle in an overdrive clutch way, after the internal combustion engine normally starts, the clutch is separated from the handle, if the reverse rotation occurs when the internal combustion engine starts, the clutch axle is separated from the starting axle under the function of the ratchet wheel structure and the shifting fork, and thereby eliminating the human damage caused by the reverse rotation force as well as the revere rotation of the internal combustion engine.
Description
Technical field
Combustion engine handle starting device of the present invention relates to the engine starting technical field, particularly the combustion engine hand lever starting technical field.International classification number is F02N1/02.
Background technique
Adopt the internal-combustion engine of hand lever starting, the counter-rotating that produces during often because of starting causes personal injury accidents, and the internal-combustion engine of the employing hand lever starting of selling in the market, its hand lever starting system does not all have Safeguard, exists potential safety hazard.
Summary of the invention
The potential safety hazard that exists when solving combustion engine hand lever starting, ensure user's personal safety, the invention provides a kind of combustion engine handle starting device, it is by starting shaft, shell, ratchet, shift fork, reverse clutch shaft, shifting fork pin, the shifting fork pin support, detent pin, ratchet, spring is formed, it is characterized in that: ratchet is assembled into one with reverse clutch shaft, be installed in the housing and and cooperate with housing is movable, starting shaft is that the cross activity connects with reverse clutch shaft one end, oppositely the clutch shaft the other end connects with the overdrive clutch form with handle, spring, detent pin is fixed on the housing base plate, ratchet one end and ratchet are slidingly matched, one shifting block is arranged on the ratchet, shifting fork pin support and housing are fixedly connected, shifting fork pin and shifting fork pin support are fixedly connected, and shift fork connects with the shifting fork pin activity, and housing is fixed on the internal-combustion engine.
Concrete implementing measure
Accompanying drawing 1 is structural representation of the present invention.
Accompanying drawing 2 is ratchet schematic representation of the present invention.
One 9 shifting blocks are arranged on 10 ratchets among Fig. 2.
2 ratchets and 4 reverse clutch shafts are assembled into one among Fig. 1, be installed in 3 housings and and cooperate with 3 housings are movable, 1 starting shaft is that the cross activity connects with 4 reverse clutch shaft one ends, the 4 reverse clutch shaft the other ends connect with the overdrive clutch form with handle, on 11 springs, 8 detent pin stuck-at-s, the 2 housing base plates, 10 ratchets, one end and 2 ratchets are slidingly matched, there are one 9 shifting blocks, 7 shifting fork pin supports and 3 housings to be fixedly connected on 10 ratchets, 6 shifting fork pin and 7 shifting fork pin supports are fixedly connected, 5 shift forks connect with 6 shifting fork pin activities, and 3 housings are fixed on the internal-combustion engine.
In the time of need carrying out hand lever starting to internal-combustion engine, handle connects with the overdrive clutch form with 4 reverse clutch shafts, handle with sleeve is also exerted oneself slightly to 1 starting shaft direction, 4 reverse clutch shafts cooperate with 1 starting shaft, firmly shake handle, obtain starting as internal-combustion engine, handle separates with 4 reverse clutch shafts, and 4 reverse clutch shafts separate with 1 starting shaft under 11 spring actions, as producing the starting counter-rotating, 2 ratchets promote the motion of 10 ratchets, 9 shifting blocks on 10 ratchets are stirred 5 shift forks, and 5 shift forks make 4 reverse clutch shafts separate with 1 starting shaft, and handle no longer reverses with 1 starting shaft, unsafe factor when eliminating counter-rotating ensures operator's personal safety.
12 housing base plates among the present invention can save, and spring, detent pin are fixed on the internal-combustion engine.
Claims (2)
